T/CERS 0036-2024 VVER nuclear power plant power-rating condition internal fire probability safety analysis (FPSA) technical requirements
Basic Information
Scope
Main technical content: The purpose of this standard is to standardize the implementation process of fire PSA in power operation mode of VVER nuclear power plants, clarify various technical elements, and provide technical requirements for the main objectives, contents, and interrelationships of these technical elements, so as to ensure the standardization of fire PSA development and guarantee the quality of its implementation. By implementing fire PSA in power operation mode of VVER nuclear power plants, important information about fire risks in this type of nuclear power plants, such as critical equipment, important cables, unfavorable equipment layouts, fire protection arrangements, and post-fire accident mitigation, can be identified. Through targeted protection or modification, the unit's ability to defend against internal fires can be enhanced.
