UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE ROAD, SUITE 210 LISLE, IL 60532-4352 May 3, 2012 Mr. Michael J. Pacilio Senior Vice President, Exelon Generation Company, LLC President and Chief Nuclear Officer (CNO), Exelon Nuclear 4300 Winfield Road Warrenville, IL 60555
SUBJECT:
DRESDEN NUCLEAR POWER STATION, UNITS 2 AND 3 - NOTIFICATION OF NRC INSPECTION AND REQUEST FOR INFORMATION
Dear Mr. Pacilio:
On July 23, 2012, the U. S. Nuclear Regulatory Commission (NRC) will begin inspection of refueling and other outage activities (NRC Inspection Procedure 71111.20) prior to the next refueling outage scheduled for the Dresden Nuclear Power Station. 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 shield plugs, drywell head, reactor pressure vessel head, steam separator, steam dryer lifting devices; (2) reactor vessel head safe load paths; and (3) reactor building crane preventative maintenance, inspections and testing. The on-site portion of the inspection will take place during July 23-27, 2012, and August 13-17, 2012.
Experience has shown that inspection of these activities is resource intensive both for the NRC inspector and the licensee staff. In order to minimize the inspection impact on the site and to ensure a productive inspection for both parties, we have enclosed a request for documents needed for the inspection. This information should be available in Region III by July 16, 2012, (preparation 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 Ms. Paula OBrien, of your organization. If there are any questions about this inspection or the material requested, please contact the inspector, Mr. V. Meghani at (630) 829-9751 or via email at Vijay.meghani@nrc.gov.
