Operational facets of a dry spent fuel cask. [Dryout and cooldown of NLI /sup 1///sub 2/ Legal Weight Truck cask]
There are several operational activities unique to a ''dry'' spent fuel cask. During loading, it is necessary to rapidly displace water and dry out the fuel cavity. During unloading, it is necessary to ''cooldown'' the hot fuel and cask internals prior to placing the cask in a spent fuel pool. Techniques for rapidly and efficiently performing dryout and cooldown were developed for the NLI /sup 1///sub 2/ Legal Weight Truck (LWT) cask at the Barnwell Nuclear Fuel Plant (BNFP). The results of this testing are reported. The techniques developed can be utilized equally well for larger dry casks such as the NLI 10/24 rail cask. The test results indicated that these dry cask operations should not cause problems during loading and unloading in excess of that experienced with a wet cask. In fact, elimination of coolant sampling and the need to meet coolant activity limits is a distinct advantage.
