ABSORBING CORE OF NUCLEAR REACTOR CONTROL ELEMENT Russian patent published in 1998 - IPC

Abstract RU 2119199 C1

FIELD: nuclear engineering. SUBSTANCE: in order to maintain initial absorption efficiency, to reduce rate of decrease of efficiency, and to improve radiation resistance and heat conductance of absorbing core, loose n,α neutron absorber having volume fraction of 10-50% is introduced in loose n,γ neutron absorber. Used as n,α absorber is boron carbide powder and as n,γ absorber, dysprosium titanate powder or grit (Dy₂O₃•TiO₂), dysprosium hafnate (nDy₂O₃•mHfO₂), or their mixtures. EFFECT: enlarged service life of control elements. 4 cl
