Problem solving skills are very important in supporting social development. Children with problem solving skills can build healthy relationships with their friends, understand the emotions of those around them, and see events with other people's perspectives. The purpose of this study was to determine the implementation of playing unplugged coding programs in improving early childhood problem solving skills. This study used a classroom action research design, using the Kemmis and Taggart cycle models. The subjects of this study were children aged 5-6 years in Shafa Marwah Kindergarten. Research can achieve the target results of increasing children's problem-solving abilities after going through two cycles. In the first cycle, the child's initial problem-solving skills was 67.5% and in the second cycle it increased to 80.5%. The initial skills of children's problem-solving increases because children tend to be enthusiastic and excited about the various play activities prepared by the teacher. The stimulation and motivation of the teacher enables children to find solutions to problems faced when carrying out play activities. So, it can be concluded that learning unplugged coding is an activity that can attract children's interest and become a solution to bring up children's initial problem-solving abilities.

Sharenting is a habit of using social media to share content that disseminates pictures, videos, information, and parenting styles for their children. The purpose of this article is to describe the sharenting phenomenon that occurs among young parents, and the importance of parenting programs, rather than protecting children's privacy. Writing articles use a qualitative approach as a literature review method that utilizes various scientific articles describing the sharenting phenomenon in various countries. The findings show that sharenting behaviour can create the spread of children's identity openly on social media and tends not to protect children's privacy and even seems to exploit children. Apart from that, sharenting can also create pressure on the children themselves and can even have an impact on online crime. This article is expected to provide benefits to parents regarding the importance of maintaining attitudes and behaviour when sharing and maintaining children's privacy and rights on social media.

ABSTRAKSaat ini wisata syariah yang biasa dikenal dengan wisata religi sedang menjamur, khususnya di Jawa Timur. Sosok yang dianggap wali oleh sebagian orang itu berada di Surabaya, Gresik, dan Tuban, namun saat ini berkembang di kabupaten Jombang, yakni makam Presiden ke-4 Abdurrahman Wahid yang disebut Gus Dur. Penelitian ini bertujuan untuk mengetahui pemahaman masyarakat dalam memanfaatkan peluang wisata religi makam Gus Dur dalam meningkatkan perekonomian masyarakat sekitar pondok pesantren Tebuireng khususnya di dusun Jalan Seblak gang III. Penelitian ini dapat dicermati melalui perubahan kehidupan ekonomi, pemanfaatan peluang usaha dan faktor penghambat bagi kepentingan usaha. Penelitian ini menggunakan metode deskriptif kualitatif dengan teknik pengumpulan data wawancara dan dokumentasi. Hasil penelitian ini menunjukkan bahwa masyarakat setempat mengalami perubahan ekonomi dengan memanfaatkan peluang untuk membangun warung di atas tanah mereka dan menyewakannya kepada pedagang luar. Ini memberikan nilai ekonomi tambahan. Namun, penjualan warung-warung tersebut dinilai tidak mencukupi, sehingga mengharuskan mereka untuk membuka usaha sampingan. Terdapat peluang yang sangat baik bagi masyarakat untuk memilih menyewakan lapaknya karena faktor penghambat yaitu keluarga, tenaga kerja, permodalan, dan rasa empati yang tinggi terhadap pedagang pendatang. Saran bagi Pemerintah Kabupaten Jombang adalah memfasilitasi masyarakat dengan pengetahuan kewirausahaan dengan mengadakan seminar agar memiliki pengetahuan dan motivasi yang tinggi untuk menjalankan bisnis.Kata Kunci: Wisata Religi Makam Gus Dur, Peningkatan Ekonomi, Peluang Usaha. ABSTRACTCurrently, sharia tourism, commonly known as religious-friendly tourism is proliferating, especially in East Java. The figure, who is considered a guardian by some people, is located in Surabaya, Gresik, and Tuban but currently developing in the Jombang district, namely the tomb of the 4th President Abdurrahman Wahid, who is called Gus Dur. This study aims to determine the understanding of the community in taking advantage of religious tourism opportunities in Gus Dur's tomb in improving the community's economy around the Tebuireng Islamic boarding school, especially in the hamlet of Street Seblak street alley III. This study can be observed through changes in economic life, utilization of business opportunities and inhibiting factors for business interests. This study uses a qualitative descriptive method with interview and documentation data collection techniques. The results of this study show that the local community is experiencing economic changes by taking advantage of the opportunity to build a warung on their land and rent it out to outside traders. It provides added economic value. However, the sales of the stalls are considered insufficient, so they require them to open a side business. There is an excellent opportunity for the community to choose to rent out their stalls because of the inhibiting factors, namely family, labour, capital, and a high sense of empathy for migrant traders. The suggestion for the Jombang Regency Government is to facilitate the community with entrepreneurial knowledge by holding seminars to have high knowledge and motivation for business interests.Keywords: Religion Tourism of Gus Dur Tomb, Economic Improvement, Business Opportunity.

Abstract Background: The “unit” for “enzymic activity” (U = 1 μmol/min) was recommended by the International Union of Biochemistry and Molecular Biology (IUB) in 1961 and is widely used in medical laboratory reports. The general trend in metrology, however, is toward global standardization through defining units coherent with the International System of Units (SI). Approach: Several proposals were advanced from the IFCC, International Union of Pure and Applied Chemistry, and IUB regarding the definition for enzymic activity as well as the terms for kind-of-quantity, units, symbol, and dimension. In 1977, international agreement was reached between these bodies and WHO that “catalytic activity” (z), of a catalyst in a given system is defined by the rate of conversion in a measuring system (in mol/s) and expressed in “katal” (symbol, kat; equal to 1 mol/s). The katal is invariant of the measurement procedure, but the numerical quantity value is not. Gaining support for the katal from the final arbiter, the General Conference on Weights and Measures, was slow, but Resolution 12 of 1999 adopted the katal (symbol, kat) as a special name and symbol for the SI-derived unit, mol/s, used in measuring catalytic activity. Conclusions: Laboratory results for amounts of catalysts, including enzymes, measured by their catalytic activity can now officially be expressed in katals and are traceable to the SI provided that the specified indicator reaction reflects first-order kinetics. The conversion from “unit” is: 1 U = 16.667 × 10−9 kat. Further derived quantities have coherent units such as kat/L, kat/kg, and kat/kat = 1.

On December 3-4, the Faculty of Humanities and Social Sciences of the People’s Friendship University of Russia (RUDN University), in cooperation with Al-Farabi Kazakh National University and the University of Texas at San Antonio, held the 7th International Conference Bilingualism, Multilingualism, Translingualism and Language Education. This unique research and practice project on bilingualism in post-Soviet countries takes place under the guidance of the International Association of Teachers of Russian Language and Literature (IATRLL). The initiators and hosts of the Conference are professors of the RUDN University U. M. Bakhtikireeva and V. P. Sinyachkin. The Conference opened with the speeches of A. V. Dolzhikova (Institute of Russian Language, RUDN University), N. S. Trukhanovskaya (Ministry of Science and Higher Education), S. Kellman (University of Texas), E. D. Suleimenova (Kazakhstanian ATRLL), L. G. Balasanian (Armenian ATRLL). Plenary papers concerned the issues of language crosscultural development, bilingualism, translation in intercultural communication. One of the key topics was the transformation of the institutional language discourse and its impact on education policy. Thematic sessions elaborated on these problems and covered the history and reality of group and individual bilingualism, theory and practice of language teaching and translation. Participants of the Knowledge Transfer workshop discussed possibilities of a systemic approach to teaching Russian for native and non-native speakers. Researchers and language teachers had a great opportunity to share their academic and practical expertise on language education and intercultural communication. In line with the previous conferences, theoretical issues of bilingualism, the study and description of its features attracted considerable attention. The Conference attracted specialists in numerous fields and served as a venue for cooperation: bilingualism today needs further discussion and searching for new answers to the long-standing questions.

The present study was carried out to assess the effect of methanol leaf extract of Uvaria chamae using Gas Chromatography-Mass Spectrum (GC-MS) to determine the phytochemicals present and its effect on the histology of midgut of maize weevil, Sitophilus zeamais. Insects were administered with 10 mg/kg of the plant extract using diffusion method where insects were put in a petri dish containing various concentrations and observed to see the stage they begin to die due to toxicity and observed for 5 min. They were collected into foil processing paper and fixed in Bouins fluid for 24 h, repacked after 24 h and folded in fresh foil immersed in buffered formalin for histopathological studies. Result revealed that a severe degeneration de-arrangement of the respiratory tract epithelial lining, secretory lining cells and gastrointestinal layers with the destruction of the muscular layer when compared with the control. The methanol leaf extracts of U. chamae were preliminary screened for the phytochemicals. The extract shows the presence of cardiac glycosides, saponin, steroids/terpenes, flavonoids, alkaloids and phenols. GC-MS analysis of the extract showed the presence of 2-nitrobenzaldehyde (4.00), malic acid (2.04), L-aspartic acid (2.00), 1, 1, dimethylhydrazine (1.86), Cedrandiol (1.75), 2-amino-4-(2-methylpropenyl)-pyrimidin-5-carboxylic acid (1.56), thiirane (1.54), mercaptoethanol (1.11) and some minor compounds. The findings indicated that methanol extract of U. chamae is rich in phyto-compounds having biological activities on the midguts’ histology of S. zeamais. Therefore, it is recommended as an alternative for the synthetic insecticide used by farmers for the preservation of stored grains. © 2021 Friends Science Publishers

The uniform scattered fields of the cylindrical wave from a parabolic surface are obtained with the theory of the boundary diffraction wave (TBDW). The non-uniform diffracted field is calculated with the regenerated vector potential and rearranged by considering the Fresnel function to obtain the uniform solution. The uniform scattered fields are calculated as the sum of the diffracted and the geometrical optic fields. The numerical analyses of the diffracted and scattered fields in both uniform and non-uniform solutions are in harmony with the literature. Full Text: PDF ReferencesBaker, B. B., Copson, E.

The idea of an adjustment to model test procedures in order to improve ship powering predictions was initially introduced many years ago as a roughness allowance because it was recognized that the basic methodology involved in predicting power from model tests yields powering estimates for ships whose hulls are smooth. Thus an increment to the smooth ship resistance was added to account for the ships’ roughness and this increment was called the roughness allowance. Later on it was recognized that the difference between the predicted and measured power was due to roughness as well as other factors and the concept of a correlation allowance coefficient designated by the symbol CA was developed for engineering and design purposes in order to obtain the most accurate ship powering predictions. The value of the correlation allowance for a specific ship is determined from the analysis of ship and model powering data. The correlation allowances for specific ships forms a database or experience factor that helps guide the powering prediction for a proposed new design. In the years following WWII, the U.S. Navy ships still had riveted hull plating or a combination of riveted and welded plating and many ships used a hot plastic finish which resulted in a relatively rough ship hull. Paints with smoother finishes were just being introduced. Hadler et al [1] discussed the impact of paint type and construction method on CA and showed that in the 20 years leading up to 1960 there was a general decrease in the CA. It was common practice at the time to assume a constant value of CA equal to 0.0005 for all ship sizes. By the early 1980' s the common ship construction practice was an all welded ship with a relatively smooth paint finish such as the Navy Milspec vinyl. The Navy ship-model correlation data was reassessed and summarized by Hagen et al [2]. The earlier data with hot plastic 205 were purposefully disregarded and a correlation allowance instruction which is a function of ship length, see Fig. 1 , was issued by Naval Sea Systems Command (NAVSEA) [3] and defined for U.S. Navy powering predictions according to the standard David Taylor Model Basin (DTMB) powering prediction method documented by Grant and Wilson [4] . The primary purpose of this paper is to examine the ship-model correlation data gathered since the early 1980' s and to see if there is a need to modify the NAVSEA CA curve. Other purposes are to examine the accuracy of the RPM prediction using the David Taylor Powering Prediction method, and to discover if there are any ship or model characteristics in addition to length that could influence the selection of CA.

This paper examines the symbolic kinematic modeling of a general 6-P-U-S (prismatic-universal-spherical) parallel kinematic manipulator (PKM). The base location of actuators has been previously shown to lead to: (i) reduction of the (motor) weight carried by the legs; (ii) elimination of the actuation transmission requirement (through intermediary joints as in the case of the Stewart-Gough platform); and (iii) most-importantly absorption of reaction-forces by the ground. We focus on using the symbolic equations to derive the conditions for type I and II singularities of this class of parallel manipulators. Based on these conditions, this system of equations is specialized to a specific configuration of the platform that has superior structural design and comparatively minimal singularities within its workspace. A series of studies were conducted to investigate the quality of workspace as well as estimate the actuation requirements for a unit payload carried over their workspace using the symbolic Jacobian model for this specialized configuration.

Abstract Introduction Cancer is the leading cause of death worldwide with elderly patients being predominantly affected. There seems to be a bias against administering chemotherapy to elderly patients with fewer elderly patients receiving chemotherapy as compared with their stagematched younger patients because of concerns about their capacity to endure treatment. To make personalized treatment decisions and to anticipate serious adverse effects, a toxicity prediction tool that can be computed at the bedside is the need of the hour. This well-validated score has not been tested in the Indian population. So, we decided to test the same score in our patients and try to correlate the score with the observed toxicity. Objectives This study was aimed to determine geriatric functional status by means of a standardized geriatric score and to correlate geriatric score with observed chemo toxicity. Materials and Methods Fifty consecutive elderly patients (age > 60 years) with a diagnosis of cancer and scheduled for chemotherapy were recruited. These patients were evaluated using the geriatric assessment tool which is based on functional, nutritional, and psychological status. After that patient’s pretherapy, chemo toxicity score or geriatric score was calculated using a published well-validated tool that consisted of 11 prechemotherapy variables as follows:a) Age of patient,b) Cancer typec) Planned chemotherapy dose,d) Planned number of chemotherapy drugse) Hemoglobin,f) Creatinine clearanceg) Geriatric questions like -i. How is your hearing?ii. Number of falls in past 6 months?iii. Can take your own medicines?iv. Does your health limit you in walking one block ? during past 4 weeksv. How much of time has your physical health or emotional problems interfered with your social activities (like visiting with friends, relatives etc.)The patients were then followed from the beginning to the end of six cycles of their chemotherapy regimen. Toxicities were noted after each clinical encounter by using the NCI-CTCAE, version 3.0.25. Results General characteristics: the mean age of participants was 66 years (standard deviation [SD] = 4.6 and range: 60–85 years). Of them, 60% received polychemotherapy and 82% received standard doses of chemotherapy. The mean score on activities of daily living was 66.7, comorbidity score was 2.7, the psychological scale was 63.8, the social-activity scale was 54.3, and social-support scale was 64.1. The mean pretherapy toxicity score is 7.24 according to the toxicity calculator. At least one grade 3 to 5 toxicity occurred in 30% of the patients (66% of grade 3, 20% of grade 4, and 13.3% of grade 5). The correlation between the predicted score and observed graded toxicity score by Pearson’s scale (α = 0.05) was 0.63. Conclusion The prediction model is easy to use, thus increasing the feasibility of incorporation in daily practice is important. It may enable oncologists to better assess the risk/benefit ratio and to adjust the treatment accordingly.

Concurrent different histopathological types of gynecologic tumors arise rarely. We present ovarian serous and cervical squamous cell carcinoma formed synchronously. A 51-year-old woman with a poor general condition was admitted with gradual distension of abdomen for 1 year with gradual loss of weight and appetite for the last three months and pain in the abdomen and irregular vaginal bleeding for the last two months. There was no family history of malignancy of genital tract, breast or colon. On examination she was cachexic, pale, dehydrated, tachypnoeic and had edema over feet. Per abdomen examination revealed solid, non-mobile palpable mass arising from pelvis. Per vaginal examination revealed large mass in pelvis and uterus can not be felt separately on per speculum examination there was small endocervical erosion, hypertrophied cervix. On per rectal examination bilateral parametria were free. Her tumor marker were evaluated and CA-125 was found to be raised (CA 125: 915.6 u/ml U/mL); rest tumor markers were normal. Cervical punch biopsy was suggestive of moderately differentiated carcinoma and pap smear was also suggestive of cervical cancer. MRI findings revealed a mass of altered signal intensity 2.5 × 1.5 × 2.2 cm with diffusion restriction and post contrast enhancement in the anterior lip of cervix and another large, lobulated predominantly solid mass, hypo intense on T1, intermediate on T2 with diffusion restriction and post contrast enhancement in the right adnexal region abutting the small bowel and sigmoid colon optimal debulking surgery with standard protocol was done. Histopathology report revealed squamous cell carcinoma of cervix, grade III and high grade serous cystadenocarcinoma of ovary. Tumour deposits from ovary were seen on right fallopian tube and right parametrium. Squamous cell carcinoma cervix involved ectocervix, endocervix and infiltrated near full thickness of cervical stroma, endomyometrium, vaginal cuff, paracervical tissue omentum and appendix were free of tumour. Twenty five right pelvic lymphnodes dissected were free of tumour, (00/25). One out of fifteen lymphnode dissected were involved with extra capsular extent, 01/15 and thirteen para aortic lymph node dissected were free of tumor. Immunohistochemistry markers: Ovarian mass-tumour cell expressed ck, vimentin, wt-1 with focal Ck positivity, no expression of ck20, p63, ck5/6 and CEA seen. Cervical tumour-tumour cells expressed ck, ck7, p63 and ck5/6 no expression of ck20, wt-1. Based on our case report we need to keep in mind that even if patient presents with symptoms pertaining to a single malignancy; still the rare possibility of synchronous malignancies should be looked for by doing proper investigations. In our case, patient had symptoms pertaining to ovarian malignancy; whereas cervical malignancy was diagnosed after investigating the patient. Histologic examination should be done properly as the prognosis depends on the malignancies being metastatic or synchronous one appropriate management should be offered in all such cases. Long term follow up of such patients should be maintained to determine the prognosis.

The emergency action level (EAL) scheme for a modular high temperature gas-cooled reactor (HTR) plant refers to the generic EAL development guidance for pressurized water reactors (PWR) with HTR modification due to its design issues. Based on reactor’s accidents analysis and consequence assessment, EAL scheme of HTR is established through the steps of category and classification. Four emergency classes are set for HTR consisting of U (Emergency Standby), A (Facilities Emergency), S (Site Area Emergency) and G (General Emergency). The Recognition Category of Initiating Condition (IC) and EAL contains A - Abnormal Rad Levels / Radiological Effluent, F - Fission Product Barrier, H - Hazards and Other Conditions Affecting Plant Safety, S - System Malfunction. The methodology for development of EALs for HTR on Fission Product Barrier and System Malfunction has some differences from PWR’s due to differences on operating mode, inherent safety features and system characteristics.

A computational framework is proposed to path follow the periodic solutions of nonlinear spatially continuous systems and more general coupled multiphysics problems represented by systems of partial differential equations with time-dependent excitations. The set of PDEs is cast in first order differential form (in time) u˙ = f(u,s,t;c) where u(s,t) is the vector collecting all state variables including the velocities/time rates, s is a space coordinate (here, one-dimensional systems are considered without lack of generality for the space dependence) and t denotes time. The vector field f depends, in general, not only on the classical state variables (such as positions and velocities) but also on the space gradients of the leading unknowns. The space gradients are introduced as part of the state variables. This is justified by the mathematical and computational requirements on the continuity in space up to the proper differential order of the space gradients associated with the unknown position vector field. The path following procedure employs, for the computation of the periodic solutions, only the evaluation of the vector field f. This part of the path following procedure within the proposed combined scheme was formerly implemented by Dankowicz and coworkers in a MATLAB software package called COCO. The here proposed procedure seeks to discretize the space dependence of the variables using finite elements based on Lagrangian polynomials which leads to a discrete form of the vector field f. A concurrent bifurcation analysis is carried out by calculating the eigenvalues of the monodromy matrix. A hinged-hinged nonlinear beam subject to a primary-resonance harmonic transverse load or to a parametric-resonance horizontal end displacement is considered as a case study. Some primary-resonance frequency-response curves are calculated along with their stability to assess the convergence of the discretization scheme. The frequency-response curves are shown to be in close agreement with those calculated by direct integration of the PDEs through the FE software called COMSOL Multiphysics. Besides primary-resonance direct forcing conditions, also parametric forcing causing the principal parametric resonance of the lowest two bending modes is considered through construction of the associated transition curves. The proposed approach integrates algorithms from the finite element and bifurcation domains thus enabling an accurate and effective unfolding of the bifurcation and post-bifurcation scenarios of nonautonomous PDEs with the underlying structures.

The mission of the Office of Hazard Identification and Reduction at the U. S. Consumer Product Safety Commission (CPSC, Commission) drives the Division of Human Factors to evaluate corrective action plans and propose redesigns of consumer products. Human factors studies and research focus on consumer product-related injuries, including assessing system design hazards for the general United States consumer population, ranging from newborns to seniors. These assessments include: usability, safety features, choking hazards, and evaluation of potential misuse of a product that could lead to injury or death. This paper will provide an overview of human factors work conducted at the CPSC and discuss how this specialized work contributes to reducing risk to the American public.

For many nuclear power plants worldwide the operation period will be extended from 40 to 60 years in the coming years. As the operation period increases the importance of knowledge of ageing mechanisms like fatigue increases. Knowlegde of the influence of the environment is crucial, since environmental fatigue is a relatively new development which is a modification to the existing assessment method and has to be projected to 60 years as well. This paper contains the results of a literature survey of environmentally assisted fatigue in nuclear power plants. It describes the current status and developments in the world. The main regulatory rules, guidelines and methods from the US, Germany, Japan, Finland and France are presented. At this moment different approaches for incorporating the effect of the coolant water environment exist, although the general trend is towards a more uniform approach worldwide. The most common approach is the incorporation of an environmental fatigue correction factor (Fen) in the fatigue derivation of the cumulative usage factor. The Fen formulas and the S-N fatigue curves differ but the general equations are: Fen = N air / N water and CUF = Σ U partial * Fen partial Alternatives like using fatigue curves including the environmental effects, using threshold criteria and calculation of an allowable Fen based on testing, are described. Research and material tests are still on-going and subject of international development. An overview of the current international state-of-the-art is presented.

U. S. commercial reactor plants are installing spent fuel storage facilities formally called Independent Spent Fuel Storage Installations (ISFSI) to provide needed storage space for spent nuclear fuel assemblies. Although this might be a primary objective for the utility that owns the plant, the U.S. Nuclear Regulatory Commission (U.S. NRC) has other priorities as addressed by ISFSI regulations in Title 10 of the Code of Federal Regulations, Part 72. These regulations establish a number of criteria that ensure that above all, the storage of spent nuclear fuel does not adversely affect the health and safety of the public or the environment. There are 3 primary ISFSI design activities that ensure the health and safety of the public and protection of the environment: site selection, storage system selection, and storage facility design. The regulatory requirements that address ISFSI site selection are found in 10 CFR 72, Subpart E, “Siting Evaluation Factors.” This section requires that potential ISFSI sites be assessed for impacts such as site characteristics that may affect safety or the environment, external natural and man-induced events, radiological and other environmental conditions, floodplains and natural phenomena, man-made facilities and activities that could endanger the ISFSI, and construction, operation, and decommission activities. All of these potential impacts must be carefully evaluated. First, the ISFSI capacity requirements should be determined. Potential sites should then be evaluated for siting impacts to ensure the site has adequate space, it can be licensed, it will minimize radiological doses to the general public and on-site workers, and construction, operation, and decommissioning won’t have a major effect on the environment or nearby population. The regulatory requirements that address storage system selection are found in 10 CFR 72, Subpart F, “General Design Criteria.” This section requires that the storage system be designed to withstand environmental conditions, natural phenomena, fires and explosions and that it includes confinement barriers, retrievability measures, and criticality safety. In order to be licensed by the U. S. NRC, all spent fuel storage systems must be evaluated to show how they meet these requirements. U.S. NRC approval of the system ensures that the requirements have been met and therefore ensure the health and safety of the public and environment are protected. The regulatory requirements that address the ISFSI design are also found in 10 CFR 72, Subpart F as well as 10 CFR 72, Subpart H, “Physical Protection.” Like the storage systems, the ISFSI site must be designed to withstand environmental conditions, natural phenomena, fires, and explosions. But the design must also include security provisions. Security features protect the spent fuel from attack or sabotage and therefore protect the health and safety of the public and the environment. The primary potential impact of spent fuel storage is radiation dose. The key regulatory requirement that addresses radiation dose is found in 10 CFR 72.104. This section requires that the dose to any individual member of the public not exceed 0.25 mSv (25 mrem) to the whole body, 0.75 mSv (75 mrem) to the thyroid, and 0.25 mSv (25 mrem) to any other organ, from exposure to direct radiation from the ISFSI, radioactive liquid or gaseous effluents, and radiation from other nearby nuclear facilities. Design features of the storage system and ISFSI include shielding by the cask enclosure, distance, berms as required, etc. to attenuate direct radiation, and confinement provisions to prevent radiological effluent leakage. The ISFSI must be located such that the cumulative doses from the ISFSI and reactor plant do not exceed regulatory requirements. Thus it can be seen that ISFSI site selection, storage system selection, and storage facility design all work together to ensure the health and safety of the public and environment are protected.

An intergranular stress corrosion cracking (IGSCC) growth model for unirradiated, thermally sensitized stainless steels and a methodology for assessment of through-wall crack growth in horizontal weld heat affected zones (HAZs) of boiling water reactor (BWR) core shrouds has been developed. This empirical model accounts for the variability of important IGSCC parameters such as coolant conductivity, stress intensity factor, K, temperature and electrochemical corrosion potential (ECP) in providing a conservative, yet realistic assessment of the crack growth rate. Data from various sources were used to derive the empirical crack growth correlation, including work from Electric Power Research Institute (EPRI)-sponsored research, work sponsored by the U. S. Nuclear Regulatory Commission (NRC) and in-plant crack arrest verification system (CAVS) data as well as laboratory data developed by the General Electric Nuclear Energy (GENE). The combined database from all the sources was evaluated to ensure that only relevant data was used in the model development. This refined database was used to derive the crack growth correlation using pattern recognition and multivariate modeling tools. For practical application to crack growth evaluation of stainless steel components, three approaches were developed for dispositions of flaws, i.e., a K-independent approach, a conservative 95th percentile K-dependent approach and a plant specific approach using actual BWR water chemistry data. An example problem representing actual BWR shroud conditions is presented that demonstrates how the current crack growth model, the weld residual stress and K can be used to perform a plant-specific evaluation of flawed shrouds. The results of this example demonstrated that significant operating periods are likely for most flawed conditions in BWR core shroud welds before ASME Code Section XI core shroud safety margins are challenged.
