Dry Cask 101 – Radiation Shielding – U.S. NRC Blog

2016/6/16This includes measuring both gamma and neutron radiation at various points around each spent fuel storage cask, including the vents in the concrete overpacks for canister-based storage systems. The amount of radiation coming through the vents varies with the storage cask design, and the fuel stored in the canister, but all canister-based systems are designed to minimize the radiation

IMPACT ANALYSIS OF SPENT FUEL DRY CASKS UNDER

The dry cask system consists of a transfer cask, used for handling and moving the multi-purpose canister OLIIpC that contains the fuel, and a storage cask, used to store the MPC and fuel on a concrete pad at the site. This paper describes the analyses of the

Westinghouse Teams with Holtec to Fortify U.S. Dry Cask

2015/9/16Westinghouse and Holtec have signed a 10-year teaming agreement to provide pool-to-pad services to U.S. nuclear sites using Holtec's dry cask spent fuel storage technology. PITTSBURGH – September 16, 2015 – Westinghouse Electric Company and Holtec International today jointly announced they have signed a 10-year teaming agreement to provide pool-to-pad services to U.S. nuclear sites

Summary of Design Criteria for Dry Cask Storage Systems for ISFSI

Point-1 is in dry storage at the ISFSIs on those sites and these two spent fuel pools (SFP)s have been decommissioned. Millstone-1 UNF is all in wet storage in the spent fuel pool at that unit. For the purposes of this report all twenty shutdown reactors with

Spent nuclear waste burial halted at San Onofre until

2018/8/24The trouble began at about 1:30 p.m. Aug. 3, as workers for a subcontractor moved the loaded spent fuel storage canister into its storage vault in the Holtec HI-STORM UMAX dry storage system, according to an Aug. 17 NRC memo.
