Conceptual Design Of The Modular Transuranic Shipping Cask Mts-54, Vojislav Banjac Dec 1992

Conceptual Design Of The Modular Transuranic Shipping Cask Mts-54, Vojislav Banjac

Nuclear Engineering ETDs

The storage, transportation, and disposal of radioactive waste has become a problem of immense proportions in the United States. This Thesis focuses on the transportation of defense transuranic (TRU) waste to the Waste Isolation Pilot Plant (WIPP) repository near Carlsbad, New Mexico. The objective of the cask conceptual design was based on the following:

  • Taking into account the latest available data on TRU waste drum mass, investigate the possibility of increased drum capacity per shipment over the current design;
  • Present a new TRU cask design with increased drum capacity and the potential for transporting both Contact-handled (CH and Remote-handled (RH ...


Risk Estimation And Expert Judgment: The Case Of Yucca Mountain, Kristin Shrader-Frechette Sep 1992

Risk Estimation And Expert Judgment: The Case Of Yucca Mountain, Kristin Shrader-Frechette

RISK: Health, Safety & Environment (1990-2002)

Professor Shrader-Frechette discusses factors responsible for acute disagreement between the federal government and Nevada citizens over potential Risks at Yucca Mountain and focuses on the use of expert judgment, concluding that some of them appear to exemplify "bad science." That aside, she argues that 1,000 year predictions cannot be made from current knowledge of geology or, e.g., institutional behavior and concludes that permanent disposal of radioactive waste is currently impossible.

Non-Linear Dynamics Of A Once-Through Steam Generator, Lamartine Nogueira Frutuoso Guimaraes Aug 1992

Non-Linear Dynamics Of A Once-Through Steam Generator, Lamartine Nogueira Frutuoso Guimaraes

Doctoral Dissertations

This dissertation presents a new analytical model for the Once-Through Steam Generator (OTSG) which is a component responsible for the primary coolant heat removal and the generation and supply of superheated steam to the turbine of the Pressurized Water Reactor (PWR) manufactured by Babcock & Wilcox (B&W) Co. This new analytical model provides the explanation of the oscillatory phenomenon observed in all PWRs manufactured by B&W that uses the OTSG as part of the steam supply system. It was found that the oscillatory behavior is related to the friction pressure drop caused by the reduction in flow area due ...


Analysis Of A Hypothetical Criticality Accident Involving Damp Low-Enriched Uo2 Powder, Benan Basoglu Aug 1992

Analysis Of A Hypothetical Criticality Accident Involving Damp Low-Enriched Uo2 Powder, Benan Basoglu

Masters Theses

In this work, we report on the development of a computer model for predicting the excursion characteristics of a postulated criticality accident involving a homogeneous mixture of low-enriched UO2 powder and water contained in a cylindrical blender. The model uses point neutronics coupled with simple lumped-parameter thermal feedback. The reactivity feedback coefficients, reactivity driving force function, and the mean generation time are computed a priori using Criticality Safety Analysis Sequences No.1(CSASlX) and No.2(CSAS25) in the SCALE-IV system. The temperature of the system is calculated using a simple time-dependent energy balance where two extreme conditions for ...

Knowledge Base Expert System Control Of Spatial Xenon Oscillations In Pressurized Water Reactors , Serhat Alten Jan 1992

Knowledge Base Expert System Control Of Spatial Xenon Oscillations In Pressurized Water Reactors , Serhat Alten

Retrospective Theses and Dissertations

Nuclear reactor operators are required to pay special attention to spatial xenon oscillations during the load-follow operation of pressurized water reactors. They are expected to observe the axial offset of the core, and to estimate the correct time and amount of necessary control action based on heuristic rules given in axial offset control strategies;Current control methods of axial xenon oscillations are knowledge intensive, and heuristic in nature. An expert system, ACES (Axial offset Control using Expert Systems) is developed to implement a heuristic constant axial offset control procedure to aid reactor operators in increasing the plant reliability by reducing ...


Nuclear Power Plant Status Diagnostics Using A Neural Network With Dynamic Node Architecture, Anujit Basu Jan 1992

Nuclear Power Plant Status Diagnostics Using A Neural Network With Dynamic Node Architecture, Anujit Basu

Retrospective Theses and Dissertations

The safe operation of a nuclear reactor in a power plant is of utmost importance to the nuclear engineering community and quite vital to creating a positive attitude towards nuclear energy among the rest of the society. This thesis is an attempt to demonstrate how Artificial Neural Networks (ANNs) can increase the operational safety of nuclear reactors by being the basis of a fault diagnostic system in a power plant. It is hoped that neurocomputing, as the science of neural networks is sometimes called, will provide a better approach to recognizing and classifying operational transients at a nuclear power plant.


The Importance Of Input Variables To A Neural Network Fault-Diagnostic System For Nuclear Power Plants, Terry L. Lanc Jan 1992

The Importance Of Input Variables To A Neural Network Fault-Diagnostic System For Nuclear Power Plants, Terry L. Lanc

Retrospective Theses and Dissertations

This thesis explores safety enhancement for nuclear power plants. Emergency response systems currently in use depend mainly on automatic systems engaging when certain parameters go beyond a pre-specified safety limit. Often times the operator has little or no opportunity to react since a fast scram signal shuts down the reactor smoothly and efficiently. These accidents are of interest to technical support personnel since examining the conditions that gave rise to these situations help determine causality. In many other cases an automated fault-diagnostic advisor would be a valuable tool in assisting the technicians and operators to determine what just happened and ...


An Artificial Neutral Network Fault-Diagnostic Adviser For A Nuclear Power Plant With Error Prediction, Keehoon Kim Jan 1992

An Artificial Neutral Network Fault-Diagnostic Adviser For A Nuclear Power Plant With Error Prediction, Keehoon Kim

Retrospective Theses and Dissertations

Since the accidents at the Three-Mile Island (TMI) and m Chernobyl nuclear power plants (NPPs), the safety of NPPs has become an even more important concern to both the nuclear power industry and the general public. The demand for safer plants has ever since. Responding to the demand, many scientists increased have investigated augmenting NPP safety in various ways. For m example, innovative reactor designs, better safety system R designs, human factor studies, stricter safety regulations, and so on, have been developed and implemented in the years since the above-mentioned accidents.
