[1J11] Verification of FRBurner module of CBZ code system: fast reactor core burn-up calculation based on OECD/NEA benchmark report.
キーワード：Verification, fast reactor, burn up calculation, doppler coefficient, sodium void worth
New module for fast reactor burn-up calculation of CBZ code system has been implement recently. Our verification work is based on one OECD/NEA benchmark report. In this report, we introduce FRBurner module briefly and show the result of burn-up calculation with FRBurner module.
Last meeting we only introduced one core(MET-1000). This time we are going to summarize 4 cores result and analyze the differences which caused by different model/method on keff, βeff, Δρvoid and Δρdoppler. Particularly, we separate sodium void reactivity into non-leakage part and leakage part therefore we can know how these differences affect reactivity respectively.
