Proposed Models for Plant-Specific Adoption of Technical Specifications Task Force Traveler TSTF-426, Revision 5, “Revise or Add Actions To Preclude Entry Into LCO 3.0.3-RITSTF Initiatives 6B & 6C”
The U.S. Nuclear Regulatory Commission (NRC) is requesting public comment on the proposed model safety evaluation (SE) for plant- specific adoption of Technical Specifications (TS) Task Force (TSTF) Traveler TSTF-426, Revision 5, ``Revise or Add Actions to Preclude Entry into [Limiting Condition for Operation] LCO 3.0.3RITSTF Initiatives 6B & 6C.'' The proposed change revises the Standard Technical Specification (STS), NUREG-1432, ``Standard Technical Specifications Combustion Engineering Plants.'' Specifically, the proposed change revises various TSs to add a Condition for loss of redundant features representing a loss of safety function for a system or component included within the scope of the plant TSs. It would replace Required Actions requiring either a default shutdown or explicit LCO 3.0.3 entry with a Required Action based on the risk significance for the system's degraded condition.
Retrievability, Cladding Integrity and Safe Handling of Spent Fuel at an Independent Spent Fuel Storage Installation and During Transportation
The regulations for packaging and transport of spent nuclear fuel are separate from requirements for storage of spent nuclear fuel. Because these regulatory schemes are separate, there is no requirement that loaded storage casks also meet transportation requirements. Integration of storage and transport regulations could enable a more predictable transition from storage to transport by potentially minimizing future handling of spent fuel and uncertainty as to whether loaded storage casks may be transported from the storage location. As part of its evaluation of integration and compatibility between storage and transportation regulations, the U.S. Nuclear Regulatory Commission (NRC) staff is reviewing its policies, regulations, guidance, and technical needs in several key areas, such as: retrievability, cladding integrity, and safe handling of spent fuel; criticality safety features and requirements for spent fuel transportation; and aging management and qualification of dual-purpose canisters and components after long- term storage. The NRC staff is reviewing the potential policy issues and requirements related to retrievability, cladding integrity, and safe handling of spent fuel as the lead issue for evaluating compatibility of storage and transportation regulations. As part of its evaluation of integration and compatibility between NRC's storage regulations and transportation regulations, the NRC is issuing this request for comment (available in the NRC's Agencywide Documents Access and Management System (ADAMS) under Accession No. ML12293A434) as the staff begins its review of NRC policies, guidance, and technical needs related to retrievability, cladding integrity, and safe handling of spent fuel.
