[2M22] Study on the effectiveness of SP3 method in a fast reactor

*Shota Ushihara1, Takanori KItada1, Satoshi Takeda1 (1. Osaka University)

Keywords:calculation code, SP3 equation, diffusion equation, fast reactor, void reactivity

Currently, for the analysis of a new type of fast reactor with high heterogeneity being developed, we developed a code using the diffusion equation and SP3 method, and calculate a transport equation for these two,we used the SN method code as the reference solution and evaluated the calculation accuracy.
