The factors influencing the level of U‐232 contamination in U‐233 are examined for heavy‐water‐moderated, light‐water‐moderated and liquid‐metal cooled fast breeder reactors fueled with natural or low‐enriched uranium and containing thorium mixed with the uranium or in separate target channels. U‐232 decays with a 69‐year half‐life through 1.9‐year half‐life Th‐228 to T1–208, which emits a 2.6 MeV gamma ray upon decay. We find that pressurized light‐water‐reactors fueled with LEU‐thorium fuel… Expand
Production of Pa-U Fuel with Proliferation Resistance by 14 MeV Neutron for Long-life Core
Protactinium-231 has an attractive potential to reduce the initial excess-reactivity and to be effectively converted to the fissile nuclide 233U through 232U. Thus 231Pa serves as the burnableExpand
Characterising U-232 and Tl-208 Buildup and Decay on Thorium-fuelled RGTT200K
Thallium-208 (Tl-208), a decay daughter of uranium-232 (U-232), is a strong 2.6 MeV gamma emitter present in significant amount in thorium fuel cycle. Its existence enhances the anti-proliferationExpand
Investigation on the effect of 238U replacement with 232Th in small modular reactor (SMR) fuel matrix
Abstract Effect of 238U replacement with 232Th in small modular reactor fuel matrix was studied. Four different 235U enrichment levels (10, 13.8, 16.5 and 19.8 wt%) were used in a pairwise manner forExpand
Minimization of the fission product waste by using thorium based fuel instead of uranium dioxide
Abstract This research discusses the neutronic characteristics of VVER-1200 assembly fueled with five different fuel types based on thorium. These types of fuel based on mixing thorium as a fertileExpand
Evaluation of multiple, self-recycling of reprocessed uranium in LWR
The multiple recycling of uranium in light-water reactors is evaluated to understand its sustainability in multiple recycling scenarios and to evaluate its impact on fuel design and the fuel cycle.Expand
The effects of U-232 on enrichment and material attractiveness over time
Abstract The effect of 232U on enrichment and material attractiveness provides a significant firewall against proliferation. Mixing 232U with natural uranium creates major obstacles to theExpand
Analysis of thorium and uranium fuel cycles in an iso-breeder lead fast reactor using extended-EQL3D procedure
Abstract Use of thorium in fast reactors has typically been considered as a secondary option, mainly thanks to a possible self-sustaining thorium cycle already in thermal reactors and due to theExpand
Comparison of the radiological hazard of thorium and uranium spent fuels from VVER-1000 reactor
Abstract Thorium fuel is considered as a viable alternative to the uranium fuel used in the current generation of nuclear power plants. Switch from uranium to thorium means a complete change ofExpand
Fuel cycle modelling of open cycle thorium-fuelled nuclear energy systems
In this study, we have sought to determine the advantages, disadvantages, and viability of open cycle thorium–uranium-fuelled (Th–U-fuelled) nuclear energy systems. This has been done by assessingExpand
Measurement of (233)U/(234)U ratios in contaminated groundwater using alpha spectrometry.
A technique for quantifying both (233)U and (234)U from alpha spectra was investigated and it was found that IPF with identification of three peaks followed by interference correction on the combined peak and a weighted average activity calculation gave satisfactory agreement with the AMS data across the ( 233)U/( 234)U activity ratio range.

Thorium fuel for light water reactors—reducing proliferation potential of nuclear power fuel cycle
The proliferation potential of the light water reactor fuel cycle may be significantly reduced by utilization of thorium as a fertile component of the nuclear fuel. The main challenge of thoriumExpand
Characteristics of a Mixed Thorium-Uranium Dioxide High-Burnup Fuel

Radiological safety experience in the fabrication of alloy plate fuels bearing 233U/Pu
The first incidence of [sup 233]U-bearing fuel fabrication in India was the production of aluminum-clad Al-[sup 233]U alloy fuel for the Kamini research reactor. The reactor physics experiments forExpand
Dose rate estimates from irradiated light-water-reactor fuel assemblies in air
It is generally considered that irradiated spent fuel is so radioactive (self-protecting) that it can only be moved and processed with specialized equipment and facilities. However, a small, possiblyExpand
