Safety design criteria for spent fuel off-reactor storage pools

This technical document establishes comprehensive guidelines for the safety design of storage pools used for spent fuel at off-site facilities within the nuclear energy sector. It defines critical technical requirements and safety principles necessary to ensure the secure containment and management of irradiated nuclear fuel materials after their removal from the reactor site. The standard addresses various aspects including pool structural integrity, thermal-hydraulic behavior, radiation shielding effectiveness, and emergency cooling systems. It provides detailed specifications for material selection, water chemistry control, and monitoring instrumentation to maintain stable conditions during long-term storage. The document also outlines procedures for ensuring isolation from potential external hazards and internal failure scenarios. By adhering to these technical criteria, operators can mitigate risks associated with decay heat removal and neutron shielding. This framework serves as a foundational reference for engineering teams designing new storage infrastructure or upgrading existing facilities. The provisions cover both normal operation and anticipated off-normal events. All design calculations and safety assessments must align with the parameters set forth in this document to guarantee public and environmental protection throughout the fuel storage lifecycle.
