Abstract:
Abstract With the rapid development of nanotechnology and its applications, a wide variety of nanomaterials are now used in commodities, pharmaceutics, cosmetics, biomedical products, and industries. The potential interactions of nanomaterials with living systems and the environment have attracted increasing attention from the public, as well as from manufacturers of nanomaterial-based products, academic researchers and policymakers. It is important to consider the environmental, health and safety aspects at an early stage of nanomaterial development and application in order to more effectively identify and manage potential human and environmental health impacts from nanomaterial exposure. This will require research in a range of areas, including detection and characterization, environmental fate and transport, ecotoxicolgy and toxicology. Nuclear analytical techniques (NATs) can play an important role in such studies due to their intrinsic merits such as high sensitivity, good accuracy, high space resolution, ability to distinguish the endogenous or exogenous sources of materials, and ability of in situ and in vivo analysis. In this paper, the applications of NATs in nanotoxicological and nanoecotoxicological studies are outlined, and some recent results obtained in our laboratory are reported.

Abstract:
Objective.To provide a clinically relevant overview of the analytical interference by contrast agents (CA) in laboratory blood test measurements.Materials and Methods.The effects of five CAs, gadobutrol, gadoterate meglumine, gadoxetate disodium, iodixanol, and iomeprol, were studied on the 29 most frequently performed biochemical assays. One-day-old plasma, serum, and whole blood were spiked with doses of each agent such that the gadolinium agents and the iodine agents reached concentrations of 0.5 mM and 12 mg iodine/mL, respectively. Subsequently, 12 assays were reexamined using1/2and1/4of these CA concentrations. The results were assessed statistically by a paired Student’st-test.Results.Iodixanol produced a negative interference on the bicarbonate (p=0.011), lactate dehydrogenase (p<0.0001), and zinc (p=0.0034) assays and a positive interference on the albumin (p=0.0062), calcium (p<0.0001), ionized calcium (p=0.0086), iron (p<0.0001), and potassium (p=0.0003) assays. Iomeprol produced a negative interference on the bicarbonate (p=0.0057) and magnesium (p=0.0001) assays and a positive interference on the calcium (p<0.0001) and potassium (p=0.0012) assays. Gadoxetate disodium produced a negative interference on the iron (p<0.0001) and zinc (p<0.0001) assays and a positive interference on the sodium (p=0.032) assay.Conclusion.CAs cause analytical interference. Attention should be given to the above-mentioned analyte-CA combinations when assessing laboratory blood test results obtained after CA administration.

Abstract:
Due to the nuclear testing, reentry and disintegration of nuclear powered satellites, nuclear reactor accidents, uranium nuclear fuel cycle and nuclear weapons production, actinides have been introduced into the environment. Proposed disposal of high-level radioactive waste in mined repositories in geologic formation as well as the storage and disposal of uranium and plutonium from weapons dismantlement are further possible sources for actinide releases to the environment. The mobilization of radionuclides in the environment has been studied for many years with the prime objective of tracing the routes by which they accumulate in the food chain and become available for human consumption. Therefore, it is necessary to have available accurate, reliable and precise analytical methods to determine actinides and fission products in environmental samples as well as their isotopic ratio. These procedures should also be as fast as possible in order to give results in radiological emergency cases to take decision for radiation protection of the environment and human beings.

In this Ph.D. thesis, different kinds of phases for liquid chromatography have been tested to achieve the separation of the interfering elements and isotopes before the mass spectrometry and -spectrometry measurements. UTEVA and TEVA extraction resin (Eichrom Industries, USA) have been packed in chromatographic column as stationary phases and used for the separation of tri, tetra and hexavalent actinides and for the separation of trivalent lanthanides (La-Eu) and actinides, respectively. IonPac CS5A and CS10 (Dionex, Sunnyvale, USA) ion chromatography column were used for the simultaneous separation of actinide and lanthanides elements and for the actinides separation. The columns were coupled on-line to an Inductively Coupled Plasma Mass Spectrometer (ICP-MS) to solve isobaric interferences between actinide and lanthanide elements and off-line to a -spectrometer to solve the energy interferences between the analytes. Moreover, an investigation on the use of the UTEVA resin and IonPac Trace Cation Concentrator II column (TCC-II from Dionex, Sunnyvale, USA) as preconcentrator columns for actinide and lanthanide elements has been carried-out.

The analytical measurements have been made by mass spectrometric as well as by radiometric techniques. ICP-MS has been used for the characterization of spent nuclear fuels in terms of actinides and lanthanides content and burn-up calculation as well as for the determination of the long-lived actinides and lanthanides in environmental samples. - and -spectrometry have been used for 241Am determination in sediments and soils samples. -spectrometry and Liquid Scintillation Counting (LSC) have been used to analyze the eluted fractions from on-batch experiments.

The results obtained with the analytical procedures developed, for spent nuclear fuel solutions as well as for environmental samples, were always compared to those obtained by other independent techniques and good agreements have been always achieved.

Abstract:
Semen analysis remains the most important diagnostic tool for the study of male infertility to date. For this reason, and because of the ease of carrying out this analysis, examination of seminal fluid should be among the first diagnostic steps in cases of suspected infertility, prior to subjecting the man’s partner to long and complex diagnostic tests. The efficacy of an examination of seminal fluid depends on the experience and ability of the seminologist, who must first undertake a subjective analysis of fundamental parameters such as motility and morphology. Moreover, laboratories specialized in such analyses may apply different criteria to the evaluation of sperm parameters, making it extremely difficult to compare tests carried out in different laboratories (1). In an attempt to resolve these problems of inconsistency, and in order to standardize laboratory techniques, a committee of experts from the WHO established guidelines for semen analysis in 1980 (an updated version was published in 1999) (2). In recent years, numerous other methods of semen analysis capable of providing in-depth diagnostic information on the fertilising capacity of spermatozoa have become available. The computer-aided sperm analysis (CASA) system is a technique for sperm analysis designed to provide objective data on sperm motility (3). Because of persisting difficulties in software set-up (4), it should not be used for routine analysis, but rather as a research tool. At the same time, significant advances have been made in the study of sperm morphology through the use of scanning and transmission electron microscopes (5). Finally, within the past decade several tests capable of evaluating the integrity of sperm components, such as the membrane, acrosome, DNA, and nuclear protein, have been developed and put into use. These more complex and costly analytical tools should be considered of secondary or tertiary importance, and are to be carried out in specific cases only after standard semen analysis. Standard semen analysis remains the first and fundamental diagnostic tool.

Abstract:
Fluorescence spectrometry is the most extensively used optical spectroscopic method in analytical measurement and scientific investigation. During the past five years more than 60000 scientific articles have been published in which fluorescence spectroscopy has been used. The large number of applications ranges from the analytical determination of trace metals in the environment to pH measurements in whole cells under physiological conditions. In the scientific research laboratory, fluorescence spectroscopy is being used or applied to study the fundamental physical processes of molecules; structure-function relationships and interactions of biomolecules such as proteins and nucleic acids; structures and activity within whole cells using such instrumentation as confocal microscopy; and DNA sequencing in genomic characterization. In analytical applications the use of fluorescence is dominant in clinical laboratories where fluorescence immunoassays have largely replaced radioimmunoassay techniques. There are two main reasons for this extensive use of fluorescence spectroscopy. Foremost is the high level of sensitivity and wide dynamic range that can be achieved. There are a large number of laboratories that have reported single molecule detection. Secondly, the instrumentation required is convenient and for most purposes can be purchased at a modest cost. While improvements and advances continue to be reported fluorescence instrumentation has reached a high level of maturity. A review of the physical principles of the fluorescence phenomenon permits one to understand the origins of the information content that fluorescence measurements can provide. A molecule absorbs electromagnetic radiation through a quantum mechanical process where the molecule is transformed from a ‘ground’ state to an ‘excited’ state. The energy of the absorbed photon of light corresponds to the energy difference between these two states. In the case of light in the ultraviolet and visible spectral range of 200 nm to 800 nm that corresponds to energies of 143 to 35.8 kcal mol-1. The absorption of light results in an electronic transition in the atom or molecule. In atoms this involves the promotion of an electron from an outer shell orbital to an empty orbital of higher energy.

Abstract:
The CPF had 4 laboratories (operation room A, laboratory A, laboratory C and analysis laboratory) in connection with reprocessing technology. The main laboratory, operation room A, has 5 hot cells. Since equipments in the main cell had been designed for small-scale verification of existing reprocessing steps, it was hardly able to respond flexibly to experimental studies on advanced technology. It was decided to remodel the cell according to the design that was newly laid out in order to ensure the function and space to conduct various basic tests. The other laboratories had no glove boxes for conducting basic experiments of important elements in the advanced reprocessing, such as actinides except U and Pu, lanthanides and so on. In order to meet various requirements of innovative technologies on advanced fuel cycle development, one laboratory is established more for study on dry reprocessing, and glove boxes, hoods and analytical equipments such as NMR, FT-IR, TI-MS are newly installed in the other laboratories in this renovation. After the renovation, hot tests in the CPF will be resumed from April 2002.

Nowadays, modelling and computer simulation are used in structure design to reduce the use of experimental investigations and laboratory tests required in a real layout structure. Using the potential-flow theory, the hydrodynamic pressure deduced from sea wave’s propagation has been computed based on the non linear theory of Stocks. The extension to the vertical breakwater (fixed bottom and floating breakwater) behaviour due to such excitations is indicated in this paper. Analytical expressions for functional performance variables of wave reflection by vertical breakwater, and stress analysis inside the breakwater have been obtained. These expressions have been numerically verified to demonstrate the capability of this analytical model.

Full text
Abstract:
Welding is an essential process in many industries and is used for both the production and repair of nuclear plant, notably pressure vessels and piping. However, traditional welding processes can cause large amounts of residual stress to be generated within the structure. Current methodology for evaluating fracture toughness from specimens containing residual stresses, e.g. BS7448, relies heavily on engineering judgement. This can result in inaccurate, albeit generally conservative, values of fracture toughness being used in defect assessments. The aim of the work presented in this paper is to investigate the use of constraint based fracture mechanics to quantify ‘unique material fracture toughness’ from laboratory specimens containing residual stresses using the ‘apparent fracture toughness’ values derived from standard fracture toughness testing. This is achieved using an analytical knowledge of the effect of residual stress on crack-tip constraint and, if incorporated into fracture toughness methodology, remove the need for unreliable residual stress relaxation methods when using weld coupons for fracture toughness assessments. A novel mechanical method for generating residual stresses in single edge notch bend specimens has been assessed analytically. In this paper, computational analysis of low and high constraint bend specimens, each with and without residual stress, is used to demonstrate the principle and validity of the proposed method.

Abstract:
The Nuclear Nonproliferation Programs Design Authority is in the design stage of the Waste Solidification Building (WSB) for the treatment and solidification of the radioactive liquid waste streams generated by the Pit Disassembly and Conversion Facility (PDCF) and Mixed Oxide (MOX) Fuel Fabrication Facility (MFFF). The waste streams will be mixed with a cementitious dry mix in a 55-gallon waste container. Savannah River National Laboratory (SRNL) has been performing the testing and evaluations to support technical decisions for the WSB. Engineering Modeling & Simulation Group was requested to evaluate the thermal performance of the 55-gallon drum containing hydration heat source associated with the current baseline cement waste form. A transient axi-symmetric heat transfer model for the drum partially filled with waste form cement has been developed and heat transfer calculations performed for the baseline design configurations. For this case, 65 percent of the drum volume was assumed to be filled with the waste form, which has transient hydration heat source, as one of the baseline conditions. A series of modeling calculations has been performed using a computational heat transfer approach. The baseline modeling results show that the time to reach the maximum temperature of the 65 percent filled drum is about 32 hours when a 43°C initial cement temperature is assumed to be cooled by natural convection with 27°C external air. In addition, the results computed by the present model were compared with analytical solutions. The modeling results will be benchmarked against the prototypic test results. The verified model will be used for the evaluation of the thermal performance for the WSB drum. Detailed results and the cases considered in the calculations will be discussed here.

Full text
Abstract:
Motivated by many design considerations, several conceptual designs for advanced reactors have proposed that the entire reactor building and a significant portion of the steam generator building will be either partially or completely embedded below grade. For the analysis of seismic events, the soil-structure interaction (SSI) effect and passive earth pressure for these types of deeply embedded structures will have a significant influence on the predicted seismic response. Sponsored by the US Nuclear Regulatory Commission (NRC), Brookhaven National Laboratory (BNL) is carrying out a research program to assess the significance of these proposed design features for advanced reactors, and to evaluate the existing analytical methods to determine their applicability and adequacy in capturing the seismic behavior of the proposed designs. This paper summarizes a literature review performed by BNL to determine the state of knowledge and practice for seismic analyses of deeply embedded and/or buried (DEB) nuclear containment type structures. Included in the paper is BNL’s review of the open literature of existing standards, tests, and practices that have been used in the design and analysis of DEB structures. The paper also provides BNL’s evaluation of available codes and guidelines with respect to seismic design practice of DEB structures. Based on BNL’s review, a discussion is provided to highlight the applicability of the existing technologies for seismic analyses of DEB structures and to identify gaps that may exist in knowledge and potential issues that may require better understanding and further research.

Abstract:
The Japan Nuclear Energy Safety Organization/Nuclear Power Engineering Corporation (JNES/NUPEC) large-scale piping test program has provided valuable new test data on high level seismic elasto-plastic behavior and failure modes for typical nuclear power plant piping systems. The component and piping system tests demonstrated the strain ratcheting behavior that is expected to occur when a pressurized pipe is subjected to cyclic seismic loading. Under a collaboration agreement between the U.S. and Japan on seismic issues, the U.S. Nuclear Regulatory Commission (NRC)/ Brookhaven National Laboratory (BNL) performed a correlation analysis of the large-scale piping system tests using detailed state-of-the-art nonlinear finite element models. Techniques are introduced to develop material models that can closely match the test data. The shaking table motions are examined. The analytical results are assessed in terms of the overall system responses and the strain ratcheting behavior at an elbow. The paper concludes with the insights about the accuracy of the analytical methods for use in performance assessments of highly nonlinear piping systems under large seismic motions.

Abstract:
A new 3D fuel behavior solver is currently under collaborative development at the Laboratory for Reactor Physics and Systems Behaviour of the École Polytechnique Fédérale de Lausanne and at the Paul Scherrer Institut. The long term objective is to enable a more accurate simulation of inherently 3D safety-relevant phenomena which affect the performance of the nuclear fuel. The current implementation is a coupled three-dimensional heat conduction and linear elastic small strain solver, which models the effects of burnup- and temperature dependent material properties, swelling, relocation and gap conductance. The near future developments will include the introduction of a smeared pellet cracking model and of material inleasticities, such as creep and plasticity. After an overview of the theoretical background, equations and models behind the solver, this work focuses on the recent preliminary verification and validation efforts. The radial temperature and stress profiles predicted by the solver for the case of an infinitely long rod are compared against their analytical solution, allowing the verification of the thermo-mechanics equations and of the gap heat transfer model. Then, an axisymmetric model is created for 4 rods belonging to the Halden assembly IFA-432. These models are used to predict the fuel centerline temperature during power ramps recorded at the beginning of life, when the fuel rod performance is still not affected by more complex high burnup effects. Finally, the predictions are compared with the experimental measurements coming from the IFPE database. This first preliminary results allow a careful validation of the temperature-dependent material properties and of the gap conductance models.
