Subject:

STP Conference Call PEB has arranged a conference call to briefly discuss the status of the unresolved items from the 2002 triennial fire protection inspection. The objective of the discussion is to determine if the issues have evolved as the licensee has been working on them, and to assure that there continues to be an interim basis to safely operate the plants until the inspections can be completed. Background material is attached.

The call will be held in the DRMA conference room at 3:30 pm CST (4:30 EST) today. The bridge number for callers is (817) 276-4475. There is no pass code necessary.

Background:

During the May-June 2002 triennial fire protection inspection, the team identified concerns that the licensee's fire safe shutdown analyses did not appear to directly support their procedures. Also, the manual actions necessary to accomplish a safe shutdown during a fire were mostly not located in approved procedures, and were not understood by operators. The licensee agreed to clarify the documentation to allow completion of the inspection within a few months. Subsequently, a new fire response procedure was issued with all the required manual actions, and a new thermal-hydraulic analyses was created to support the control room evacuation scenario as the bounding case. This analysis identified that the procedural limit for cooldown rate would not allow the plant to meet the performance requirements of Appendix R,Section III.L.

Objective: To understand any changes to the scope of the issues that have evolved since the conclusion of the inspection as a result of the licensee's investigation, analyses, and procedure changes. This is intended to assure there continues to be an interim basis for assuring the safe operation of the plant until the remaining issues can be inspected, as well as supporting the prioritization of scheduling inspection resources.
