FIELD: nuclear power engineering.
SUBSTANCE: proposed fuel assembly affording supercritical neutron-physical state under normal operating conditions of nuclear reactor and subcritical state of fuel assembly during loss-of-coolant and boiling accident has vertical process channel accommodating fuel elements mounted on supporting blocks which are alternating with absorbing blocks of which at least some of them are provided with cavity communicating with process channel space and filled with absorber in the form of boron powder enriched by boron-10 isotope conveyed in emergency situations by boiling coolant into process channel. Some of absorbing blocks accommodate combustible absorber.
EFFECT: enhanced inherent ability of self-protection and safety of pressurized-tube reactors.
