Evaluation of nuclear spent fuel dry storage casks and storage facility designs
Koeberg Nuclear Power Station (KNPS) is the only nuclear power station in Africa and it stores its spent nuclear fuel (SNF) onsite in the spent fuel pool (SFP). Additional aged SNF assemblies are stored in dry storage casks in a facility located on the KNPS site. This minor research dissertation …

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 …

Analytical Separation of Zirconium-95 and Niobium-95 from Uranium Irradiated by Thermal Neutrons
The presence of zirconium and niobium in nuclear spent fuel is undesirable, both because these metals interfere seriously with later Fuel reprocessing steps, and because of the high level of penetrating gamma radiation emitted by radioactive zirconium and its daughter niobium. In this thesis, after …

Spent Nuclear Fuel Self-Induced XRF to Predict Pu to U Content
The quantification of plutonium (Pu) in spent nuclear fuel is an increasingly important safeguards issue. There exists an estimated worldwide 980 metric tons of Pu in the nuclear fuel cycle and the majority is in spent nuclear fuel waiting for long term storage or fuel reprocessing. This study …

Target Design and Optimizations for Spent Fuel Transmutation
… fission products (LLFPs) identified in nuclear spent fuel, which account for at least 99% of the long-term radiotoxicity once actinide recycling is completed. This thesis examines the feasibility of using proton beams to transmute LLFPs into shorterlived or stable isotopes. While …
