Material and Method: Thorium oxide fuel burn up calculation of a simulated research reactor cooled heavy water has been proposed in the present work using MCNPX 2.6 code.

India has chalked out a nuclear power program based on its domestic resource position of uranium and thorium. The first stage started with setting up the Pressurized Heavy Water Reactors (PHWR) based on natural uranium and pressure tube technology. In the second phase, the fissile material base will be multiplied in Fast Breeder Reactors using the plutonium obtained from the PHWRs. Considering ...

Thorium, in this case, 232Th has a higher thermal neutron capture cross-section than 238U, which means that more fertile isotopes can be transmuted and could lead to fissile isotope 233U. In addition, 233U good performance the spectrum. Theoretically, nuclear reactor using thorium fuel also last longer one uranium fuel. The use of TRISO duplex is predicted produce better neutronic behavior pebb...

Neutronic analysis on the Molten Salt Reactor FUJI-12 using fissile material 235U in LiF-BeF2-UF4 has been carried out. The problem faced use of thorium-based fuel is that amount 233U small and not available nature. was produced through 232Th breeding at a cost $46 million/kg. That very high price when compared to enrichment, which only $100/kg. MSR used this study generation IV reactor with mi...

In this paper, I will explore China's possible position in upcoming FMCT negotiations, China’s major security concerns, the kind of verification provisions that could be accepted by China, and the factors that might facilitate China’s participation in the treaty.

Nuclear proliferation risks from fusion associated with access to weapon-usable material can be divided into three main categories: 1) clandestine production of fissile material in an undeclared facility, 2) covert production of such material in a declared and safeguarded facility, and 3) use of a declared facility in a breakout scenario, in which a state begins production of fissile material w...

France ended fissile material production for military purposes in the 1990s and has started to decommission and dismantle its production facilities at Marcoule and Pierrelatte. This paper provides an overview of the French production complex and presents new estimates of historic fissile-material production, which include neutronics calculations for the production reactors at Marcoule. The anal...
