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

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.
TLDR
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.
