Abstract

Abstract

To study the applicability of utilization of Inert Matrix fuels（IMF） in PWR, the variations of infinite multiplication factor k_inf, fuel temperature coefficient D_c, moderator temperature coefficient M_TC with PuO₂ volume fractions in two typical IMF fuels, PuO₂+ZrO₂+MgO and PuO₂+ThO₂, are calculated and analyzed. And the preliminary acceptable design regions of IMF fuels composition to satisfy the negative D_c and M_TC are obtained.
- Inert Matrix Fuel（IMF）,
- Fuel temperature coefficient,
- Moderator temperature coefficient,
- Acceptable design region
