UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 1.0 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.

1 TO FACILITY OPERATING LICENSE NO. NPF-63 CAROLINA POWER 5 LIGHT COMPANY NORTH CAROLINA EASTERN MUNICIPAL POWER AGENCY SHEARON HARRIS NUCLEAR POWER PLANT UNIT 1 DOCKET NO. 50-400 INTRODUCTION By letter dated Hay 14, 1987, the Carolina Power

& Light Company (CP8L or the licensee) submitted an amendment to the Technical Specifications (TS) for the Shearon Harris Nuclear Power Plant, Unit 1 (SHNPP).

This sub-mittal requested changes in the Technical Specifications which will permit operation of SHNPP with continuous discharges of liquid effluent from releases currently permitted by the TS.

This change would permit greater operational flexibility, particularly during periods when high volumes of liquids are required to be processed.

The licensee has also proposed

- changes to the monitoring and surveillance requirements appropriate for operation in the proposed manner.

2.0 EVALUATION The FSAR for SHNPP indicates that the maximum expected effluent from the Secondary Waste System (SWS) is 25,000 gallons per day.

This effluent flows from the SWS Tank past the radioactive effluent monitor designated REN-3542 to the cooling tower blowdown line where it becomes mixed with the blowdown flow before flowing into Lake Harris.

In the current mode of operation, batches of secondary system liquid waste are discharged in this way, with monitor REMI-3542 set to alarm and terminate flow if radioactive concentrations exceed the limits specified in 10 CFR 20, Appendix B, Table II, Column 2.

The changes to the TS proposed by the licensee would permit continuous releases.

These releases would be monitored for flow and radioactivity with provisions for alarm and release termination should the activity levels of the effluent exceed the limits specified in 10 CFR 20, Appendix B, Table II, Column 2.

The change in the mode of operation will affect parts of the Offsite Dose Calculation Manual which concern adjusting the setpoints of radioactive liquid effluent monitors to maintain concentra-tions less than those stipulated in 10 CFR 20, Appendix B, Table II, Column 2 to address tha case of simultaneous releases and for lower-limit radioactivity detection.

Other parts of the ODCM must also be corrected to address procedures for continuous releases and the accounting of all radioactive quantities in liquid effluents.

A revision to the ODCM, containing the necessary corrections, must be submitted with the next semi-annual radioactive effluent report.

No changes are being made in the daily volume released; nor will the concentration of the effluent exceed the limits of 10 CFR 20, Appendix B, Table II.

Therefore, the dose limits of 10 CFR 50, Appendix I, Section II.A will not be exceeded, based on the analysis in the Final Environ-mental Statement Related to the Operation of Shearon Harris Nuclear Power

Plants, Units 1 and 2, NUREG-0972, October 1983.

Thus, the discharge of radioactivity can be maintained as low as is reasonably achievable.

3.0 ENVIRONMENTAL CONSIDERATION

This amendment involves a change in the'nstallation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes in surveillance requirements.

The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumu-lative occupational radiation exposure.

The Commission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such find-ing.

Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).

Pursuant to 10 CFR 51.22(b) no environmental impact statement or enviromental assessment need be prepared in connection with the issuance of this amendment.

4.0 CONCLUSION

The Commission made a proposed determination that the amendment involves no significant hazards consideration which was published in the Federal Re ister (52 FR 20797) on June 3, 1987, and consulted with the state oF ort arolina.

No public comments or requests for hearing were

received, and the state of North Carolina did not have any comments.

The staff has concluded, based on the considerations discussed

above, that:

( 1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed

manner, and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
