Question:
Y'our submittal indica tes that dropping a fuel assembly within a storage cell could cause the bottom plate welds to fail.
Please provide a statement as to whether the spent fuel pool liner would be perforated as a result of this accident.
Response
We have determined the fuel assembly velocity required to perforate the stainless steel liner using methodology developed for tornado missile impact analysis.
Using the submerged weight of a fuel assembly dropped from 30 inches above the top of the rackI but neglecting all drag forces due to water or impact with cell walls or bottom plate<
the velocity of the fuel assembly on impact is not sufficient to perforate the liner.
