ARTICLES: long-ting-time neutron-temperature dynamics of fast-neutron systems in supercritical emergency regimes

摘要

The results of experimental and computational investigations of the long-time (≤60 h) behavior of the BIR-2M and BIGR pulsed reactors with abrupt transfer into a supercritical state under conditions with no externally initiated reactivity changes are presented. These conditions simulate possible incidents when all mechanisms for regulating reactivity and emergency protection fail.
