Depletion Calculations For An Integral Small Molten Salt Reactor With Serpent

Abstract The molten salt reactor (MSR) concept is among the Generation IV designs considered feasible for providing clean, safe, sustainable, and economical energy supplies to world's population. depletion of fuel a small modular fluoride (sm-FMSR) with closed cycle based on integral (IMSR) has been investigated using Serpent. Three fueling schemes control Serpent cycles have simulated compared: step (SF), continuous all fission products (FPs) accumulating in system (CFA), insoluble FPs separated from (CFS). Sm-FMSRs SF CFA require similar quantities "top-up" fuel, consume (fissile) amounts, result isotopic concentrations if keff kept within range. However, separation circulating CFS gains large reactivity worth due removal FP poisons. This allows reduction enrichment both initial total top-up leads savings considerable fissile quantity MSR spent fuel. calculations manual arithmetic adjustment built-in settings before start every calculation three schemes. Implementation additional flow features changing material volumes constants would facilitate simulation process allow more realistic simulations circulation.
