September 24, 2004 Mr. Jay K. Thayer Site Vice President Entergy Nuclear Vermont Yankee P.O. Box 0500 185 Old Ferry Road Brattleboro, VT 05302-0500 RE:
Information for Presentation to ACRS
Dear Mr. Thayer:
Pursuant to 30 V.S.A. § 206, this letter requests that information be provided to the Department. The documents and information are needed by the Department to prepare a presentation to the Advisory Committee on Reactor Safeguards (ACRS) regarding Entergy's request for extended power uprate.
On September 17, 2004, as part of our ongoing responsibilities related to oversight of Vermont Yankee, we asked the ACRS to allow us to make a presentation on Entergy's request to change Vermont Yankee's design basis to take credit for containment overpressure to demonstrate the adequacy of emergency core and containment cooling pumps. In order to properly make this presentation, we need a number of Vermont Yankee documents and related information. Although we believe that Nuclear Regulatory Commission (NRC) power uprate review staff should also review this information as part of their review, we are not aware that you have provided this information to the NRC review staff. Therefore, these documents are not in our possession.
- 1. Please provide us with a copy of the following documents. When calculations are requested, the request includes the latest revision and all applicable calculation change notices (CCN's).

- 2.
Please identify whether it is feasible to replace RHR and CS spray pumps with pumps which do not require crediting containment overpressure for NPSH adequacy. If you have determined that such replacement is not feasible, please identify the reasons for such a determination.
- 3.
Please identify the highest uprated power level possible for Vermont Yankee for which Vermont Yankee would not have to request changing its design basis to take credit for containment overpressure to demonstrate NPSH adequacy for any of the events: large and small break LOCAs, SBO, ATWS, Appendix R fires, and 2
,~./
Mr. Jay K. Thayer Information for Presentation to ACRS September 24,2004 stuck open SRVs. Please provide copies of the calculations you have used to determine this highest uprated power level without taking overpressure credit.
In addition, if Entergy intends at ACRS to support its overpressure credit design basis change request with risk and probabilistic information, we would request to meet with you to discuss your probabilistic modeling and assumptions related to containment overpressure credit.
In order to prepare for the ACRS meeting, the information above is requested by October 15,2004.
Sincerely, David O'Brien, Commissioner NRC State Liaison Officer
