Pased on the infonnation provided in tha SAD and ny review, I conclude that the containaent recuirc ents of 10 CFR 471.51 are satisfied.

A containc.ent criteria is established based on conservatively assuning that all of the'fr-F.5 fron the fuel having the raxirur inventory of The al{mtable release rate is established and a leakarJe test of 1x10 gen those considered is released into the cask cavity under nornal condit atr-crf /s is specified.

The 1x10~U ate-cr /s leck test is to be satisfie.1 usinq a balonen detector test. The test shotil1 Fe perfomed periodically; the period for testing should he specified as no rore than one year prior to shitnent (i.e.,

freauency of no less than annually).

The onoratine procedures (Segtion 7) call for a leak test having a sensitivity of lx10~" at ren /s prior to each shipnent. A hubble test is specifie! in the S/#. to satisfy the specified sensitivity. The test should Le perforned prior to each shionent.
