In accordance with the criteria established by 10 CFR 50.73 entitled Licensee Event Re ort S stem the following report is being submitted:

LER 315/99-019-00, "Victoreen Containment High Range Radiation Monitors Not Environmentally Qualified to Withstand Post-LOCA Conditions."

The following new commitments were identified in this LER.

A permanent solution for the susceptibility of the HRRMs to moisture intrusion will be developed to support HRRM operability in Modes 1'-4. Options for the permanent solution are currently under review and will be implemented prior to Mode 4 for each unit.

An evaluation of the as-built configuration for other low signal current application EQ equipment is being performed to identify additional electrical equipment that may be susceptible to moisture intrusion due to a LOCA or pipe break condition.

The evaluation will include a review of the current EQ Program documentation regarding requirements for leaktight electrical enclosures. This evaluation will be by September 30, 1999. Based on results of the evaluation, appropriate'ompleted corrective actions will be taken to address any identified EQ discrepancies.

Sincerely, 4A M. W. Rencheck
