UNITEDSTATES NUCLEAR REGULATORY COMMISSION WASHINGTON, O. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.
87 TO FACILITY OPERATING LICENSE NC.
NPF<<14 AND AMENDMENT NO. 53 TO FACILITY OPERATING LICENSE NO. NPF-22 PENNSYLVANIA POWER 5 LIGHT COMPANY ALLEGHENY ELECTRIC COOPERATIVE INC.
DOCKET NOS. 50-387 AND 50-388 SUSQUEHANNA STEAM ELECTRIC STATION UNITS I AND 2 1.0
2.0 INTRODUCTION
By letter dated November 9, 1988, Pennsylvania Power 5 Light Company requested an amendment to Facility Operating License Nos.
NPF-14 and NPF-22 for the Susquehanna Steam Electric Station (SSES),
Units 1 and 2.
The proposed amendments would delete the Technical Specifications relative to the drywell floor drain sump flowrate monitor of the Reactor Coolant Leakage Detection System.
The sump level monitors will continue to remain in the Technical Specifications.
EVALUATION The licensee, in its November 9, 1988 application, indicates that the flowrate monitoring system is not a part of the original design basis of the SSES Reactor Coolant Leakage Detection System but was vo'tuntarily installed by the licensee as a redundant system to the floor drain sump level monitors.
The flowrate monitoring system was included in the Technical Specifications by Amendment No. 36, dated April 12, 1985.
The licensee states that the flowrate monitors have never provided accurate leakage measurements.
The current Technical Specifications permit continued operation of the plant when both the level monitoring channels are inoperable, but the inaccurate flowrate monitors are operable.
The licensee has concluded that such an action is non-conservative and the removal of the flowrate monitors from the Technical Specifications would make the action statement of the level monitors more conservative such that the continued operation of the plant will be prevented when both drywell floor drain sump level channels are inoperable.
By removing the flowrate monitors from the Technical Specifications and applying the Action Statement to the level monitors, the licensee is re-establishing the conservatism intended in the design basis of the SSES.
The staff agrees with the licensee's assessment and finds the proposed changes acceptable.

- 3. 0 ENVIRONMENTAL CONSIDERATION These amendments involve changes to a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes to the surveillance requirements.
The staff has determined that these amendments involve no significant increase in the amounts, and no significant change
<n the types, of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure.
The Commission has previously issued a proposed finding that these amendments involve no significant hazards consideration and there has been no public comment on such finding.
Accordingly, these amendments meet the eligibilitycriteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement nor environmental assessment need be prepared in connection with the issuance of these amendments.
4.0 CONCLUSION
The Coamission made a proposed determination that these amendments involve no significant hazards consideration which was published in the Federal
~Re ister (53 FR 58334) on December 14, 1988 and consulted with the Sta7eeo Pennsylvania.
No public comments were received, and the State of Pennsylvania did not have any cooeents.
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 Cmeission's regulations and the issuance of these amendments will not be inimical to the common defense and security nor to the health and safety of the public.
