Findings in the Sandbed Region During 1R22 SU*e IATFOO SPVV0ORS Findings in the Sandbed Region During 1R22 FROM: Tim Rausch, Site Vice President DATE: Monday, Nov. 17, 2008 INSTRUCTIONS: Please review the following information with all employees.

We have sent a memo to the NRC Commissioners that informs them of the results of our epoxy coating inspections of the drywell shell during the 2008 refueling outage.

Thethree items outlined in the memo are:

• The condition of the epoxy coating

• The condition of the moisture seal

• The water found in three bays The memo updates a previous communication to the Commissioners from November 6 in which we described a dime-sized blister that was found in one location in the epoxy coating on the outside surface of the drywell in the sandbed region.

The dime-sized blister was caused by a small amount of salt left on the drywell shell before the coating was originally applied in 1992. That small, blistered area has been repaired.

The epoxy coating remains in good shape and the drywell continues to meet all safety standards, with margin. AmerGen's aging management program for the drywell remains solid. We are going to continue to fulfill our inspection commitments to the NRC.

V The moisture seal continues to perform its designed function. AmerGen has repaired a few areas of the moisture seal that became cracked over the past two years. We did identify an area of uncured caulk in Bay 3. That caulk has been in an uncured condition since it was installed in 1992, and it has not, and will not have any adverse impact on the integrity-of the drywell shell.

We found some water entering three of the bays in the sandbed region. The source of this water is the reactor cavity, and that is only filled with water during a refueling outage, so we know this will not occur when the plant is operating. There is no concern that water will enter the sand bed region during normal operations because the reactor cavity is drained and closed at those times.

Throughout the entire license renewal process, we have been open, honest and forthcoming with the NRC, and everything that we found supports our projections that the integrity of the epoxy coating and the continued safe operation of the drywell is accurate.

Please remember that we expect the NRC to issue our plant a renewed license before it is set to expire in April 2009. If for some reason the NRC has not granted us a renewed license by April, we can nevertheless continue to operate beyond April while the Commission's review continues, and we plan to continue providing New Jersey with this clean electricity that the state needs."

While the issue of the license extension is being resolved, let's stay focused on our job at hand: The safe operations of Oyster Creek. Let's continue to demonstrate our industry-leading performance.
