PALISADES NUCLEAR PLANT NOTIFICATION OF NRC TI-172 INSPECTION AND REQUEST FOR INFORMATION

Dear Mr. Schwarz:

On May 19, 2008, the NRC will begin the inspection for Temporary Instruction 2515/172, Reactor Coolant System Dissimilar Metal Butt Welds, at the Palisades Nuclear Plant. This on-site inspection is scheduled to be performed May 19 through May 23, 2008, and June 2 through June 6, 2008.

In order to minimize the impact to your on-site resources and to ensure a productive inspection we have enclosed a request for documents needed for this inspection. These documents should be available to the inspector 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 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. B. Dotson, of your organization. If there are any questions about this inspection or the material requested, please contact the lead inspector Mr. D. Jones at (630) 829-9622.
