Nuclear characteristics of Pu fueled LWR and cross section sensitivities Takeda, Toshikazu [Osaka Univ., Suita (Japan). Faculty of Engineering] 21 NUCLEAR POWER REACTORS AND ASSOCIATED PLANTS; MIXED OXIDE FUELS; PWR TYPE REACTORS; BWR TYPE REACTORS; CRITICALITY; SELF-SHIELDING; DOPPLER EFFECT; SENSITIVITY ANALYSIS; GROUP CONSTANTS; PLUTONIUM OXIDES The present status of Pu utilization to thermal reactors in Japan, nuclear characteristics and topics and cross section sensitivities for analysis of Pu fueled thermal reactors are described. As topics we will discuss the spatial self-shielding effect on the Doppler reactivity effect and the cross section sensitivities with the JENDL-3.1 and 3.2 libraries.
