May 31, 2012 Mr. Adrian P. Heymer, Executive Director Strategic Programs Nuclear Energy Institute 1776 I St NW, Suite 400 Washington, DC 20006-3708
SUBJECT:
ENDORSEMENT OF ELECTRIC POWER RESEARCH INSTITUTE (EPRI)
DRAFT REPORT 1025286, SEISMIC WALKDOWN GUIDANCE
Dear Mr. Heymer:
On behalf of the Nuclear Regulatory Commission (NRC), I am responding to the Nuclear Energy Institutes (NEIs) letter1 of May 29, 2012, Final Draft of Industry Seismic Walkdown Guidance (EPRI 1025286), which requested NRCs endorsement of Draft 7 of EPRI Report 1025286, Seismic Walkdown Guidance, dated May 2012 (hereafter, EPRI guidance document). NEIs letter was submitted to support licensee responses to Enclosure 3 of the March 12, 2012, information request2 that was issued pursuant to Title 10 of the Code of Federal Regulations (10 CFR), Section 50.54(f) (hereafter, 50.54(f) letter). The 50.54(f) letter was issued in the course of implementing the lessons learned from the accident at the Fukushima Dai-ichi nuclear facility.
The NRC staff would like to acknowledge that this document was the product of significant interaction between the NRC, NEI, and other stakeholders at numerous public meetings. These interactions and the insights gained from them allowed for the development of this document in a very short time-frame.
The NRC staff confirmed that the EPRI guidance document directs licensees to perform walkdowns in a manner that will address the Requested Information items 1.a through 1.g in the 50.54(f) letter. Additionally, the NRC staff finds that Section 8, Submittal Report, of the EPRI guidance document delineates the appropriate information to be submitted in response to Requested Information items 2.a through 2.f. of Enclosure 3 of the 50.54(f) letter.
As described above, the NRC staff has reviewed the EPRI guidance document and finds that performance and reporting of seismic protection walkdowns in accordance with this document would be responsive to the 50.54(f) letter. In addition, the EPRI guidance document also incorporates the suggestions made by the Advisory Committee on Reactor Safeguards during a subcommittee meeting on May 22, 2012.
1 The Agencywide Documents Access and Management System (ADAMS) Accession No. of NEIs May 29, 2012, letter was not available at the time this letter was issued.
2 The 50.54(f) letter is available in ADAMS under Accession No. ML12053A340.
The NRC requests that EPRI publish a final version of the guidance document within one month of receipt of this letter. The final version should incorporate this letter between the title page and the first section and remove the draft markings from the document. If you, or your staff, have additional questions, please contact myself or Mr. Christopher Gratton at 301-415-1055, or by email at Christopher.Gratton@nrc.gov.
Sincerely,
/RA/
