Subject:

LaSalle County Nuclear Power Station Response to Generic Letter 94-02 (BWR Stability)

NRC Dockets 50-373 and 50-374

Reference:

1) September 9,1994 letter from John C. Brons to William T.

Russell, Comed BWR response to Generic Letter 94-02 (BWR Stability).

2) July 11,1994 NRC Generic Letter 94-02, "Long-Term Solutions and Upgrade of Interim Operating Recommendations for Thermal-Hydraulic Instabilities in Boiling Water Reactors".

3) June 6,1994 letter from L. A. England to M. J. Virgilio, "BWR Owners' Group Guidelines for Stability Interim Corrective Action".

Guidelines identical to those in BWROG-94078 letter to all BWR owners dated June 6,1994.

The Reference 1 letter transmitted the LaSalle County Station response to NRC Generic Letter 94-02 concerning BWR stability (Reference 2). The letter responded to Reporting Requirement 1 of the generic letter; informing the NRC of the licensee's plans and status with respect to the actions requested by the generic letter. The generic letter also included Reporting Requirement 2, which requires informing the NRC upon completion of the generic letter actions. The purpose of this letter is to inform the NRC that Requested Action 1 to Generic Letter 94-02 has been completed.

Requested Action 1 to Generic Letter 94-02 requested the licensee to review their current procedures and training programs and modify them as appropriate to strengthen the administrative provisions intended to avoid power oscillations or to detect and suppress them if they occur prior to implementation of the long-term solutions. In response to Requested Action 1, LaSalle County Station implemented actions consistent with or more conservative than the BWROG Interim Corrective Actions (ICAs) guidelines described in Reference 3. The procedure changes and training required to implement these guidelines were completed on December 28, 1994. These guidelines are intended to be used only until the long-term stability solution is implemented. At that time, appropriate procedure changes will be made which recognize the automatic protection and operator warning features of the long-term solution.
