Calculation of temperature coefficients of reactivity for EBR-II kinetic analyses

Conference ·
OSTI ID:6346308
;

Temperature coefficients of reactivity for use in coupled neutronics-thermohydraulics kinetics codes, as for example the EROS code used for Experimental Breeder Reactor-II (EBR-II) kinetic analyses, are both loading and problem-modeling sensitive. To enable appropriate temperature coefficients to be calculated for differing loading configurations and differing subassembly groupings in the kinetics analyses, an addition ((TEMCO) has been made to the EBRPOCO code. EBRPOCO calculates detailed axially-delineated contributions of the linear and Doppler components of the power-reactivity-decrement (PRD) for every subassembly and control rod location in an EBR-II configuration. This paper provides the results of the EBR-II kinetics analysis and lists the temperature coefficients of reactivity for varying subassembly types and conditions.
