SUBJECT:
MILLSTONE NUCLEAR POWER STATION, UNIT 3, FACSIMILE TRANSMISSION, DRAFT REQUEST FOR ADDITIONAL INFORMATION (RAI) TO BE DISCUSSED IN AN UPCOMING CONFERENCE CALL (TAC NO. MB4556)
The attached draft RAI was transmitted by facsimile on June 3, 2002, to Mr. Ravi Joshi, Dominion Nuclear Connecticut, Inc. (DNC). This draft RAI was transmitted to facilitate an upcoming conference call in order to clarify certain items in the licensees response dated April 2, 2002 to NRC Bulletin 2002-01, regarding reactor pressure vessel head degradation and reactor coolant pressure boundary integrity. Review of the RAI would allow DNC to determine and agree upon a schedule to respond to the RAI.

DRAFT REQUEST FOR ADDITIONAL INFORMATION Reactor Pressure Vessel Head Degradation and Reactor Coolant Pressure Boundary Integrity (TAC NO. MB4556)
- 1. Your 15 day response to Bulletin 2002-01 stated that Millstone Unit 3 had one leak that could have resulted in boric acid reaching the reactor pressure vessel (RPV) head. Discuss whether or not there was any evidence that the boric acid did, in fact, reach the RPV head. Discuss the magnitude of the leak and the amount of boric acid deposits that were found on the insulation.
- 2. Clarify whether or not the bare metal visual inspection for Millstone Unit 3 will include 100%
of the vessel head penetrations (and the corresponding surface area of the RPV head).
