SUBJECT: MILLSTONE POWER STATION - NRC INTEGRATED INSPECTION REPORT I'
05000336/2010003 AND 05000423/2010003 II'
Dear Mr,
Heacock:
On June 30,2010, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at I
your Millstone Power Station Unit 2 and Unit 3. The enclosed inspection report documents the inspection results, which were discussed on July 21, 2010, with Mr. A. J, Jordan and other members of your staff.
The inspection examined activities conducted under your license as they relate to safety and I
compliance with the Commission's rules and regulations, and with the conditions of your I license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
This report documents one Severity Level IV non-cited violation (NCV). This report also documents four self-revealing findings of very low safety significance (Green). Two of these findings were determined to involve a violation of NRC requirements. However, because of the very low safety significance and because they have been entered into your corrective action program, the NRC is treating these violations as NCVs, consistent with Section VI.A. 1 of the NRC Enforcement Policy. If you contest any NCV in this report, you should provide a response within 30 days of the date of this inspection report. with the basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator. Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Senior Resident Inspector at Millstone. In addition, if you disagree with the cross-cutting aspect assigned to any finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region I, and the NRC Senior Resident Inspector at Millstone. In accordance with Title 10 of the Code of Federal Regulations (CFR) Part 2.390 of the NRC's
"Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRC's document system {ADAMS}.
ADAMS is accessible from the NRC Web Site at http://www.nrc.gov/reading~rm/adams.html (the Public Electronic Reading Room).
