FAST REACTOR Russian patent published in 1999 - IPC

Abstract RU 2142169 C1

FIELD: nuclear reactors. SUBSTANCE: according to invention, moderator such as B^II4C is introduced in fast reactor so as to soften neutron spectrum. Growth in activity occurring in case of coolant loss is reduced in this way at all points of reactor. Moderating element may be mixed up with nuclear fuel or with material other than that in homogeneous form or placed in heterogeneous form in special needle members mounted among needle members containing nuclear fuel or other material. EFFECT: reduced space factor and improved Doppler constant. 6 cl, 3 dwg
