NUCLEAR REGULATORY COMMISSION

[NRC-2009-0448]


Notice of Availability of Final Interim Staff Guidance Document 
No. 25 ``Pressure and Helium Leakage Testing of the Confinement 
Boundary of Spent Fuel Dry Storage Systems''

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.
