Abstract:

This document gives an overview of the proposed MSc study. The main goal of the study is to model the cases listed in the code benchmark study of the International Atomic Energy Agency CRP–6 fuel performance study (Verfondern & Lee, 2005). The platform that will be employed is the GETTER code (Keshaw & van der Merwe, 2006). GETTER was used at PBMR for the release calculations of metallic and some non–metallic long–lived fission products. GETTER calculates the transport of fission products from their point of fission to release from the fuel surface taking into account gas precursors and activa

Abstract:

The releases of hazardous substance from pressurised pipelines are of particular interest due to the different scenarios that may occur following the loss of containment. These may have different causes, as accidental release, corrosion, etc. In such cases the release of flammable substances can lead to different scenarios as Fires, Explosions and Environmental pollutions. The severity of such scenarios can increase due the "Domino Effect" that will affect also other equipment or near unit operations, potentially causing a cascading event. For these reasons an accurate methodology is necessary

Abstract:

Decision-making models have, m the recent years, been developed to provide systematic and comprehensive tools to analyse, evaluate and manage freight movement. Freight transport models developed thus far have not precisely defined risk agents brought by travelling vehicles, which lead to indistinct risk types. Instead, most of the models developed discussed the risks mainly related to direct impacts by traffic accidents. On the other hand, transport efficiency, which is of more and more concern, has not been sufficiently emphasised in the previous models. This thesis studies the factors in

In the last decade, extraction of unconventional oil and gas (UOG) has rapidly increased in Canada.

Flowback water is stored on site before being transported for treatment, reuse or disposal. It is stored in containment pond, above ground walled storage s

Abstract:

Previous experiments demonstrated that the accidental release of high pressure hydrogen into air can lead to the possibility of spontaneous ignition. It is believed that this ignition is due to the heating of the mixing layer, between hydrogen and air, caused by a shock wave that is driven by the pressurized hydrogen during the release. Currently, this problem is poorly understood and not amenable to direct numerical simulation. This is due to the presence of a wide range of scales between the sizes of the blast wave and the very thin mixing layer. The present study addresses this fundamental

Multi-criteria decision aid has emerged from the operational research field as the answer given to a couple of important questions encountered in complex decisions problems. Firstly, as decision aiding tools, such methods do not replace the decision maker with a mathematical model, but support him to construct his solution by describing and evaluating his options. Secondly, instead of using a unique criterion capturing all aspects of the problem, in the multi-criteria decision aid methods one seeks to build multiple criteria, representing several points of view. <p>This work explores the appli

<p>Small modular reactors (SMRs) are expected as a suitable candidate to fulfill energy needs in the future. The regulation of the emergency planning zone (EPZ) has been a controversial issue. The possibility of smaller EPZs because of their small core size and passive safety functions is still under discussion. The major emergency responses to radiological incidents in the early phase are evacuation from the area and shelter-in-place within a building. Comparison between the dose incurred during evacuation and that with shelter-in-place is necessary to consider the proper protective actions.

For this final paper, I chose a rather serious topic that is very topical in our society. Hazardous chemical substance ? ammonia ? is used very widely at present. Ammonia is used as a coolant in various plants. I have compiled a list of all plants in South Bohemia that work with ammonia, including ice rinks. I characterized the properties of ammonia, what damage it causes to the human organism and the environment. I noted a list of accidents during which there have been ammonia leakages of ammonia and I analyzed one accident using a software programme called TerEx. I chose the building of the

Many petroleum and petrochemical companies are now required to regularly involved in preparing safety reports in the emergency response planning. In order to complete the safety reports, a number of calculations must be completed, including fluid release rate in case of vessel or pipe failure, and subsequent evaporation and dispersion of a toxic or flammable vapor

碩士<br>淡江大學<br>化學工程學系<br>85<br>Safety has become one of the major concerns in the chemical process industry today. How the chemical company manages safety within the plant directly affects the well-being of the entire community. To help ensure safe plant operations, we must understand and manage the hazards associated with toxic and flammable chemicals. For the protection of plant personnel and the surrounding community, emergency preparedness and response pro

Abstract:

In the light of almost daily media reports of accidents and incidents of violence in South African schools, it can be assumed that most South African schools are unsafe. This study investigates the manner in which rural public schools implement the school safety regulations prescribed by the South African Schools Act to ensure learner safety. This qualitative study investigates the implementation of the Schools Act’s safety regulations at four public schools situated in the rural areas east of Pretoria in Gauteng. Data was gathered using interviews with the principals of these schools as well
