Re: NPSH for BWR Extended Power Upgrades (EPU)

Paul, Bill Ruland forwarded your email to me since I am the NRR Vermont Yankee project manager.

The NRC plans to review the Vermont Yankee Extended Power Uprate (EPU) amendment request using NRC Review Standard RS-001. A copy of RS-001 can be found on our website at:

http://www.nrc.gov/reactors/operating/licensing/power-uprates.html#relatedregs RS-001, Section 2.6.5 discusses the specific review criteria we will use to evaluate the effects of the EPU on NPSH.

As discussed in the attached letter from the NRC to Entergy dated 12/15/03, the staff has requested Entergy to provide further information related to the CPPU topical report you referenced as well as providing the technical information needed to support the review areas contained in RS-001.

Please let me know if you have any questions.

Bill:

During my search of ADAMS I came across a letter authored by you addressed to General Electric dated March 31, 2003. This letter is titled "REVIEW OF GE NUCLEAR ENERGY LICENSING TOPICAL REPORT NEDC-33004P, REVISION 3, "CONSTANT PRESSURE POWER UPRATE" I also noted NEOD-33090 dated September 2003 titled "SAFETY ANSAYSIS REPORT FOR VERMONT YANKEE NUCLEAR POWER STATION CONSTANT PRESSURE POWER UPRATE" I note that both of these documents discuss the requirements for the NPSH for the ECCS pumps however, the specific review criteria seems to be missing from my copy of these documents.

If my memory serves me correctly, I recall that there are specific criteria for post LOCA NPSH contained within Regulatory Guides 1.1 and 1.82 and also Generic Letter 97-04. Could you please explain to me why these criteria are apparently not part of the acceptance criteria for

the Vermont Yankee upgrade? It may be possible that I have only reviewed the non-proprietary copies of these documents and the proprietary version contains the missing information. If this is the case, please confirm this.

I would also appreciate a list of other BRW upgrades where these criteria may not have been specifically addressed during the NRCs review process.
