AGENCY:

Nuclear Regulatory Commission.

ACTION:

Notice of availability.

SUMMARY:

The Division of Spent Fuel Storage and Transportation (SFST) of the Office of Nuclear Materials Safety and Safeguards (NMSS) is issuing its Interim Staff Guidance Document No. 25 (ISG-25) “Pressure and Helium Leakage Testing of the Confinement Boundary of Spent Fuel Dry Storage Systems.” This ISG supplements standard review plan guidance for evaluating the helium leakage testing and ASME Code required pressure (hydrostatic/pneumatic) testing that is specified for the cask confinement boundary. It specifies the acceptance tests that are necessary to clearly demonstrate that the cask has been fabricated in accordance with the design criteria, and that the operation of the cask complies with the intended safety bases of the confinement system and regulatory requirements. The final ISG-25 is available in the NRC's Agencywide Documents Access and Management System (ADAMS) under the Accession No. ML101970493.
