Description

If the fuel rods of nuclear reactor are damaged, the fission gases such as 131I will be released to the reactor building, increasing the risk of internal exposure to personnel. The analysis on CRP1000 unit showed that it can lead to the internal exposure risk to personal even if only one of the fuel rods is damaged. As the fuel damage increased to 0.25% of operation limitation, protective measures are required even if the purify system is turned on. The radioiodine hazard control and protection measures of 131I are discussed with reference to the practical nuclear power plant operation experience. (authors)
