HYPER (HYbrid Power Extraction Reactor) is the accelerator-driven transmutation system developed by KAERI (Korea Atomic Energy Research Institute). HYPER is designed to transmute long-lived transuranic actinides and fission products such as Tc and I. HYPER adopts a fast neutron system and Pb-Bi is used as core coolant and target material. Pb-Bi corrosion is one of the main factors considered to...

spring 1944. Work at Los Alamos, Oak Ridge, and Hanford to design, build, and provide fissionable material for the first atomic bombs was shifting into high gear. In stark contrast, initial bomb project studies on the nuclear chain reaction and plutonium were winding down at the Chicago Metallurgical Laboratory, Argonne National Laboratory’s wartime predecessor. Even as others zeroed in on the ...

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...

The source of all liquid, gaseous and solid radioactive waste in the pressure water reactor (PWR) nuclear power plant (NPP) originate from leakage of fission products out of the fuel rods into the primary coolant and neutron activation of materials within and around the primary coolant system and reactor vessel. The source term design used to determine the concentrations of radionuclides in the...

Small modular reactors (SMRs) are those nuclear fission reactors with electrical output powers of less than 300 MWe. Due to its inherent safety features, the modular high temperature gas-cooled reactor (MHTGR) has been seen as one of the best candidates for building SMR-based nuclear plants with high safety-level and economical competitive power. Power-level control is crucial in providing grid...

Advances in computational methods have given rise to the study and simulation of different aspects reactor behavior. As such, topics associated with high costs become feasible candidates for further investigation one them is space-time kinetics (STK). Until recently, STK point approximation were limited deterministic codes, Monte Carlo codes being too costly start with. However, recent developm...
