Cook Nuclear Plant Unit 2 NRC BULLETIN 96-01:

CONTROL ROD INSERTION PROBLEMS The purpose of this letter is to provide additional information regarding NRC Bulletin 96-01.

NRC Bulletin 96-01 was sent to all holders of pressurized water reactor operating licensees to alert them to problems encountered during recent events in which control rods failed to completely insert upon a scram signal and to request an assessment of the operability of control rods, particularly in high burnup fuel assemblies.

Our initial response to Bulletin 96-01 was transmi,tted to the NRC via letter AEP:NRC:1249 dated April 8, 1996.

Donald C.

Cook Nuclear Plant Unit 2 is currently operating in its eleventh fuel cycle.

Information regarding assembly burnup for this cycle is contained in the attachment to this letter.

As discussed in our initial response, this information was not available in April 1996, when the available requested information was transmitted.

Sincerely, SWORN TO AND SUBSCRIBED BEFORE ME THIS ~~tg DAY OF 1996 E.
