UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE ROAD, SUITE 210 LISLE, IL 60532-4352 July 22, 2009 Mr. Timothy J. OConnor Site Vice President Monticello Nuclear Generating Plant Northern States Power Company, Minnesota 2807 West County Road 75 Monticello, MN 55362-9637
SUBJECT:
MONTICELLO NUCLEAR GENERATING PLANT - NOTIFICATION OF NRC INSPECTION AND REQUEST FOR INFORMATION
Dear Mr. OConnor:
On January 25, 2010, the NRC will begin inspection of refueling and other outage activities (NRC Inspection Procedure 71111.20) prior to the next refueling outage scheduled for the Monticello Nuclear Generating Plant. This inspection will utilize NRC Operating Experience Smart Sample: (OpESS) FY 2007-03, Revision 2, Crane and Heavy Lift Inspection, supplemental guidance for IP-71111.20, issued September 12, 2008. This inspection will focus on the impact of load handling activities on the reactor core and its cooling and plant support systems. Specifically, this inspection will review applicable design and licensing bases, engineering design and analysis, procedures, and surveillances associated with the reactor vessel head removal and installation during refueling outages including: (1) Reactor building crane preventative maintenance, inspections and testing; (2) reactor vessel head rigging equipment; (3) reactor vessel head drop analysis (or single failure proof crane or equivalency);
and (4) reactor vessel head safe load paths. The on-site inspection is scheduled to take place on January 25-29, 2010, and February 8-12, 2010.
Experience has shown that inspection of these activities is resource intensive both for the NRC inspector and licensee staff. In order to minimize the inspection impact to the site and to ensure a productive inspection for both parties, we have enclosed a request for information needed for the inspection. This information should be available in Region III by January 18, 2010, (preparatory week). It is important that all of these documents are up to date and complete in order to minimize the number of additional documents requested during the preparation and/or the on-site portions of the inspection.
We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Mr. Ron Baumer, of your organization. If there are any questions about this inspection or the material requested, please contact the inspector, Mr. J. Bozga, at (630) 829-9613.
T. OConnor In accordance with 10 CFR 2.390 of the NRC's Rules of Practice, a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of 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).
Sincerely,
/RA/

CRANE AND HEAVY LIFT INSPECTION DOCUMENT REQUEST Inspection Dates: January 25-29 and February 8-12, 2010 Inspection Procedures: IP 71111.20, Refueling and Other Outage Activities Lead Inspector: John V. Bozga (630) 829-9613 I. Information Requested for In-Office Preparation Week The following information (paper copy if practicable, unless otherwise indicated) is requested to be available in Region III on January 18, 2010. If you have any questions regarding this information, please call the inspector as soon as possible.
A copy of the following documents related heavy load control during removal or installation of the reactor vessel head:
(1) Monticello submittals as a result of NRC December 22, 1980, unnumbered Generic Letter (GL) (now NRC numbered as GL 80-113) and GL 81-07, Control of Heavy Loads regarding NUREG-0612, Control of Heavy Loads at Nuclear Power Plants, six-month response (Phase I) and nine-month response (Phase II). Final Supplement to Safety Evaluation Report related to NUREG 0612, Phase I and Phase II, if applicable.
