SUBJECT:

CLINTON POWER STATION - NOTIFICATION OF NRC SUPPLEMENTAL INSPECTION (95001) AND REQUEST FOR INFORMATION

Dear Mr. Pacilio:

In a telephone conference on June 23, 2014, your staff at the Clinton Power Station informed the U.S. Nuclear Regulatory Commission (NRC) that the Clinton facility was ready for the NRC to perform a supplemental inspection using NRC Inspection Procedure (IP) 95001, Supplemental Inspection for One or Two White Inputs in a Strategic Performance Area.

On July 7, 2014, the NRC will begin the IP 95001 supplemental inspection. This on-site inspection is scheduled to be performed July 7 through 11, 2014. The purpose of this inspection is to provide assurance that the root causes and contributing causes of the performance issues associated with the White performance indicator for Unplanned Scrams per 7000 critical hours are understood, the extent of condition and extent of cause of the failures are identified, and your corrective actions are sufficient to address the root and contributing causes to prevent recurrence.

To minimize the impact to your onsite resources and to ensure a productive inspection, we have enclosed a request for documents needed for this inspection. It is important that all of these documents are up to date and complete, thereby minimizing the number of additional documents requested during the preparation and/or the onsite 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. Jim Patterson of your organization.

If there are any questions regarding our schedule or the materials being requested, please contact Robert Ruiz at 815-357-8611. He may also be reached electronically at robert.ruiz@nrc.gov.

M. Pacilio 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 System (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

/RA/
