摘要
FIELD: nuclear physics.;SUBSTANCE: invention relates to nuclear reactor control rod. Mid spacer (3) of neutron transparent material is arranged between the jacket and column of pellets made of B4C neutron absorbing material, over at least the height of said column. Said spacer is composed of the structure (3) of increased heat conductivity and exposed porosity. Note here that said structure can be deformed at compression over its depth. Besides, this invention discloses the appropriate fabrication processes.;EFFECT: prevented interaction between absorber and jacket, possibility of release of gaseous products of neutron absorption reactions.;21 cl, 3 dwg
