Dear Mr. Barnhart:

The recent discovery of cracks in the fuel basket of the CASTOR V/21 cask used in the Virginia Electric and Power Company / Department of Energy (VEPC0/00E) dry j h < spent fuel storage cooperative demonstration program is of great interest to  !

l us. We recognize that these cracks were discovered after the cask had been i

! involved in a demonstration under conditions exceeding the design basis set  !

4 forth in your "Tcpical Safety Analysis Report For the CASTOR V/21 Cask [

l Independent Spent Fuel Storage Installation (Dry Storage)," Revision 1. However,

i in view of these developments since our approving the topical report and considering potential impacts on the licensed use of the CASTOR V/21 cask, we [

l request you provide us with an analysis and evaluation of the cause(s) of the  ;

j cracking found in the demonstration cask. Also, please assess the need, if  !

j any, to' revise your Topical Safety Analysis Report and provide any necessary  ;

changes along with the appropriate analysis. Because the use of a CASTOR V/21 i

cask at an independent spent fuel storage installation requires a site-specific i i safety evaluation and a license, we intend to hold in abeyance any supplemental I action on our approval of your Topical Safety Analysis Report of the CASTOR s

V/21 cask pending receipt and review of your analysis.  ;

i . t

We are coordinating with VEPC0 and DOE on this matter. As more information [

l becomes available we may contact you with more specific requests. However, in t i the mean time, if you have any questions or if we can be of any assistance to  !

l you, please contact me or John Roberts at (301) 427-4205. j l Sincerely, [

i  !
