COMPUTATIONAL EVALUATIONS AND REGULATION OF RADIOACTIVE FISSION PRODUCT SOURCES DURING ANALYSIS OF RADIOLOGICAL CONSEQUENCES FOR ACTIVE AND PLANNED NUCLEAR POWER PLANTS WITH VVER

摘要

The principles and approaches to evaluating a source of fission products when analyzing radiological consequences are described. Some of them were developed by adjusting previously used approaches. The most important and fundamental of these adjustments is an approach to regulating the number of leaky fuel elements for normal operation regimes in the calculation of the operational limit on the activity of fission products in coolant, for which the maximum admissible radioactive emissions and the irradiation dose due to them to the population living near a plant are not exceeded.
