Preliminary study on plutonium and minor actinides utilization in thorims-nes minifuji reactor

Preliminary study on weapon grade uranium utilization in molten salt reactor miniFUJI

“…The molten salt reactor miniFUJI has a core height and diameter of 2 m and 2 m, respectively [1]. The original thermal power output of miniFUJI is 10 MWe.…”

“…THORIMS-NES miniFUJI reactor is a small power MSR which originally considers Th/ 233 U or Th/Pu as main fuel. Study on plutonium and minor actinides utilization in THORIMS-NES miniFUJI reactor has also been carried out [1]. In this paper, we will report a preliminary study on weapon grade uranium utilization in MSR miniFUJI in order to evaluate the capability of miniFUJI reactor to burn highly enriched uranium from dismantling of nuclear weapon.…”

A comparative analysis of the neutronic performance of thorium mixed with uranium or plutonium in a high‐temperature pebble‐bed reactor

“…The heterogeneous design concept, also known as the seed and blanket (S&B) concept, uses the driver fuel in the seed region and thorium in the blanket region, while the homogeneous design uses a mixture of the driver fuel and thorium. 9 In addition, research into the use of thoriumbased fuels has progressed beyond traditional water reactors to include molten salt reactors (MSRs), [10][11][12] breeder reactors (BR), [13][14][15] and high-temperature gas reactors (HTGRs). 16 The HTGR concept is one of six concepts for the fourth generation of nuclear reactors.…”

Comparative Studies on Plutonium and Minor Actinides Utilization in Small Molten Salt Reactors with Various Powers and Core Sizes

“…Since this reactor works in continuous mode with the liquid fuel, the difference of the power density can be assumed to be adjusted by changing the the flow rate of the fuel salt. By supposing that the thermal efficiency of miniFUJI reactor is about 40%, these two thermal outputs can be regarded as 10 MWe and 20 MWe, respectively [5].…”
