CALCULATION OF EMERGENCY SITUATIONS OCCURRING DURING THE CONVERSION OF THE RESEARCH REACTOR AT THE INSTITUTE OF NUCLEAR PHYSICS OF THE ACADEMY OF SCIENCES OF THE REPUBLIC OF UZBEKISTAN

摘要

Calculations of emergency situations occurring during the conversion of the WR-SM reactor at the Institute of Nuclear Physics of the Republic of Uzbekistan are presented. Results are presented for the following situations: motion of a compensating rod (two cases), loss of electric power, and obstruction of a fuel assembly. It is shown that safety is maintained for all the emergency situations which were analyzed and the behavior of all zones which were analyzed is actually identical. The computational results will be used for the conversion of VVR-SM to low-enrichment fuel.
