SUBJECT: FORT CALHOUN STATION - NOTIFICATION OF INSPECTION NRC INSPECTION REPORT (05000285/2009005) AND REQUEST FOR INFORMATION
Dear Mr. Bannister:
On November 9, 2009, reactor inspectors from the Nuclear Regulatory Commission's (NRC) Region IV office will begin baseline inservice inspection activities at Fort Calhoun, using NRC Inspection Procedure 71111.08, "Inservice Inspection Activities," and TI 2515/172, "Reactor Coolant System Dissimilar Metal Butt Welds." Experience has shown that this inspection is a resource intensive inspection both for the NRC inspectors and your staff. In order 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. These documents have been divided into two groups. The first group (Section A of the enclosure) identified information to be provided prior to the inspection to ensure that the inspectors are adequately prepared. The second group (Section B of the enclosure) identifies the information the inspectors will need upon arrival at the
site. 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 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. Erick Matzke of your licensing organization. The tentative inspection schedule is as follows:
Preparation Weeks: November 2 - 9, 2009 Onsite weeks: November 9 - 20, 2009
Our inspection dates are subject to change based on your updated schedule of outage
activities. If there are any questions about this inspection or the material requested, please contact the lead inspector Gerond George at (817) 276-6562 (Gerond.George@nrc.gov) or Isaac Anchondo at (817) 860-8152 (Isaac.Anchondo@nrc.gov).

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/
