NORTH ANNA UNITS 1 AND 2 RE: BURNUP IN LEAD FUEL RODS (TAC NOS. MA5269 AND MA5270)

Dear Mr. O'Hanlon:

This letter is in response to your request to exceed 60,000 MWD /MTU lead rod burnup in a small number of fuel rods in North Anna Unit 2. The small number of lead rods will be included in a reconstituted fuel assembly to be inserted into the core for one cycle. The intent is to obtain data on fuel and material performance to support a goal of extending the current burnup limits.

i The NRC staff has no objection to your requested use of such rods in a reconstituted fuel

]

assembly.

i By letter dated April 16,1999, and supplemented July 28,1999, you requested approval to exceed a 60,000 MWD /MTU lead red burnup limit for a small number (8) of lead fuel rods within a reconstituted fuel assembly. Although there are no NRC regulations or plant technical

{

specifications which impose a lead rod burnup limit, a limit of 60,000 MWD /MTU was stated by us in a letter dated December 14,1993.

The staff has reviewed your proposal and, as set forth in the enclosed safety evaluation, has no objecJion to it. Accordingly, it is acceptable to exceed 60,000 MWD /MTU for a small number of lead rods.

In addition, you asked that certain terminology be clarified. In particular, you would like the optional replacement of non-failed fuel rods by filler rods to be included in the term,

" reconstituted fuel assembly." We have reviewed yourjustification and agree that this l

interpretation should not impact compliance with NRC requirements on the use of reconstituted fuel and is acceptable.

This concludes our effort on this issue and we are closing TAC Nos. MA5269 and MA5270.

Sincerely, Original signed by:
