[Global] [EXTERNAL] Dry Cask Campaign Exposure

Wed Sep 28 11:14:52 EDT 2022

TMI recently completed an ISFSI campaign in which we loaded 47 NAC MAGNASTOR casks in one continuous campaign working 24/7.  We normalized the per cask exposure to a standardized Gamma Figure of Merit (GFOM) to compare each cask on the basis of exposure while factoring in the various burn-up, heat load, enrichment, age, etc.  See below.

Figures include the neutron component in addition to gamma.

Some of the fuel had been stored for just two years following permanent shutdown.  I also attached additional information in a Power Point presentation.

What is the exposure per canister everyone is averaging when performing Dry Cask?
