SUBJECT:

NRR CONTACTS FOR AE0D RECOMMENDATION TRACKING As requested in your memorandum of January 15, 1986, we have reviewed the AE0D recommendation status sumaries you sent us. NRR staff contacts for the programs in which the recomendations are being addressed have been updated and are indicated on the enclosed marked-up copies of the status. sumary sheets. Per the telephone conversation between K. Seyfrit of your staff and M. Caruso of mine, we are forwarding the information regarding corrected contacts to you now- ?

and will send over any very recent updates to the status of the recommendations following review by the Division of Safety Review and Oversight (DSR0). It is our understanding that the status of recomendations was updated by your staff in December 1985.

l In addition, I am enclosing a copy of my December 30, 1985 memorandum to NRR Division Directors which will help you in the future to identify NRR contacts for generic issues being resolved.
