Allocation of spent nuclear fuel transport casks
The selection of the form of spent nuclear fuel disposition, currently under debate, will precipitate an immediate requirement for spent-fuel transport regardless of the disposition alternative chosen. In this study, a constrained transportation model of the spent fuel cask scheduling problem is …

Cosmic ray muons for spent nuclear fuel monitoring
<p>There is a steady increase in the volume of spent nuclear fuel stored on-site (at reactor) as currently there is no permanent disposal option. No alternative disposal path is available and storage of spent nuclear fuel in dry storage containers is anticipated for the near future. In this …

Spent Nuclear Fuel Disposal Liability Insurance (Environmental Economics)
This thesis examines the social efficiency of nuclear power when the risks of accidental releases of spent fuel radionuclides from a spent fuel disposal facility are considered. The analysis consists of two major parts. First, a theoretical economic model of the use of nuclear power including the …

Radioisotope Inventory Of Spent Nuclear Fuel In Mathematica
While nuclear reactors in the United States have produced economy-driving power for several decades, they have also left behind a significant amount of spent nuclear fuel. The federal government, ultimately responsible for this spent fuel, has a history just as long in attempting to effectively …

Determination of economic shelf life of spent nuclear fuel
… is to determine the constituents of value in spent nuclear fuel and integrate these results into an economic time dependent model of a spent fuel assembly. The value of the constituents in the spent fuel is balanced against the cost of the various nuclear fuel cycle services. BWR and …

A dynamic multi-criteria analysis of spent-nuclear-fuel alternatives
… decisions is developed for the analysis of the spent-nuclear-fuel management problem. The generalized model is decomposed into two subproblems. First is a multiple-objective R&D capital budgeting problem and second is a multiple-objective fuel allocation problem. Goal programming is selected as …

Waste characteristics of spent nuclear fuel from a pebble bed reactor
… comparative assessment is made of the spent fuel characteristics and disposal aspects between a high-temperature, gas cooled, reactor with a pebble bed core (PBR) and a pressurized water reactor (PWR). There are three significant differences which impact the disposal characteristics of …

Optimization of time and location dependent spent nuclear fuel storage capacity
In this study a linear spent fuel storage model is developed to identify cost-effective spent nuclear fuel storage strategies. The purpose of this model is to provide guidelines for the implementation of the optimal time-dependent spent fuel storage capacity expansion in view of the current …

An optimal withdrawal policy for spent nuclear fuel from on-site storage
The need to extend light water reactor spent-fuel on-site storage requirements and the future need to relieve resulting stockpiles necessitates the determination of optimal spent-fuel-withdrawal patterns under various end-use scenarios. End-use scenarios include no-economic- return throwaway and …

Alteration mechanisms of spent nuclear fuel and characterization of potential uranium secondary phases.
… progresses along two pathways, alteration of spent nuclear fuel and identification of said alteration. The relative abundance of uranium as an energy resource, coupled with the high costs of spent nuclear fuel reprocessing and the associated risks of nuclear proliferation make a strong case …

Improving heat transfer in spent nuclear fuel disposal packages using metallic void fillers
Disposal packages containing high heat generating spent nuclear fuels (SNF) require improved heat transfer to keep the peak cladding temperature from going above the tolerance limit. Filling the accessible void spaces between the container and the SNF with a high heat conducting metal is a …

Thermal stress analysis of thermally sprayed coatings on a spent nuclear fuel waste package
… of applying a thermal sprayed coating on a spent nuclear fuel waste package is to prevent moisture contacting the spent nuclear fuel for tens of thousands of years. This thesis studies some of the thermal effects that a coated waste package may experience. Residual stress from the thermal …

On selection and operation of an international interim storage facility for spent nuclear fuel
Disposal of post-irradiation fuel from nuclear reactors has been an issue for the nuclear industry for many years. Most countries currently have no long-term disposal strategy in place. Therefore, the concept of an intermediate nuclear spent fuel storage facility has been introduced as a method of …

Electrochemical and Modelling Studies on Simulated Spent Nuclear Fuel Corrosion under Permanent Waste Disposal Conditions
… models for the deep geological disposal of spent nuclear fuel require a fundamental understanding of the corrosion of spent fuel in a failed waste container. The overall research goal of this project is to investigate the corrosion of simulated spent fuel under permanent disposal conditions, …

Physics and engineering aspects of South Africa's proposed dry storage facility for spent nuclear fuel
… electricity generation sources. Civilian use of nuclear power dates back to the 1950s. The United States of America and France are currently leading with the highest nuclear power generation in the world, generating 101 GWe and 63 GWe, respectively. Several countries such as China and the United …
