Description

The development of nuclear power engineering with closing of a fuel cycle and the use of fast reactors must ensure a higher level of ecological safety of the population and the environment. The highest ecological effect is achieved by recycling of spent fuel and isolation of long-lived radionuclides (90Sr, 137Cs and 99Тс) and transmutation of 99% of americium. In normal operation of CNFC facilities exposure doses to the population are formed via different critical pathways: for a rector plant – due to inhalation intake of 3Н, for fabrication and refabrication module – due to inhalation of Pu aerosols, for SNF recycling module – due to external radiation from the soil and ingestion in case of surface contamination of plants. The use of nitride fuel generates large amounts of 14С (270 g per 1 ton fuel). Insolubilizing most of 14С ensures compliance with the project standards for the population exposure to the gas phase of release.
