. %r f SAFETY EVALUATION'BY THE OFFICE OF NUCLEAR REACTOR. REGULATION RELATED TO AMENDMENT NO. 56 TO FACILITY OPERATING LICENSE NO. NPF-38 LOUISIANA POWER AND LIGHT COMPANY WATERFORD STEAM ELECTRIC STATION, UNIT 3 DOCKET NO. 50-382 L

1.0 INTRODUCTION

By application dated June 12, 1989, Louisiana Power and Light Company (LP&L or the licensee) requested chances to the Technical Specifications (Appendix A to Facility Operating License No. NPF-38) for Waterford Steam Electric Station, Unit 3. The proposed changes would increase the

~

frequency of channel calibrations from quarterly te monthly on the waste gas holdup system explosive gas monitoring system.

2.0 DISCUSSION The gaseous waste. management system is designed to prevent or preclude explosive mixtures. The gas analyzers used to detect potentially explosive mixtures and alert the operators depends upon oxygen and hydrogen monitors. The original plant equipment has proven to be unreliable'and the licensee has replaced the original system with one that meets or exceeds the requirements of the old system. The new system operability, however, depends upon channel calibrations performed on a monthly basis as opposed to quarterly as currently required by the Technical Specifications. We have reviewed the proposed change to the Technical Specifications and discussed the comparisons between the old and new analyzers. The new analyzers are sufficient to provide the needed protection of the gaseous waste management system and the. proposed change to the Technical Specifications are to the vendors requirements to check operability by a monthly' channel calibration. We agree with the licensee's actions and with the proposed Technical Specification change.

3.0 CONTACT WITH STATE OFFICIAL The NRC staff has advised the Administrator, Nuclear Energy Division, Office of Environmental Affairs, State of Louisiana of the proposed determination of no significant hazards consideration. No comments were received.
