NUCLEAR CHARACTERISTICS OF MULTIREGION-LOADED REACTOR CORES

Technical Report ·
OSTI ID:4337468
Multiregion cylindrical reactor cores are studied in which new fuel is loaded into oniy one annular region with the other regions being occupied by fuel in different stages of burnup. Fuel utilization, power distribution, and control requirements are determined for a model in which the region-averaged thermal fluxes are used to determine the fuel characteristics as a function of time. Results are compared with those obtained for reactor cores which are loaded uniformly and burn out at a rate determined by the region averaged fluxes. (auth)
