UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 175 TO FACILITY OPERATING LICENSE NO.
DPR-23 CAROLINA POWER & LIGHT COMPANY H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 DOCKET NO. 50-261
1.0 INTRODUCTION
By letter dated December 10, 1995, as supplemented August 1, 1996, and September 4, 1996, the Carolina Power & Light Company (licensee) submitted a request for changes to the H. B. Robinson Steam Electric Plant, Unit No. 2 (HBR), Technical Specifications (TS). The requested changes would revise TS Section 3.5.1 and Tables 3.5-2, 3, and 4 concerning the reactor trip system (RTS), engineered safety feature actuation system (ESFAS), and isolation function. The TS would be revised to (1) specify actions to be taken when an instrument channel becomes inoperable, (2) add an "Applicable Conditions" column that defines the applicability and/or mode of operation of each functional unit, and (3) make editorial enhancements. The August 1, 1996, and September 4, 1996, letters provided administrative changes to the TS pages that did not change the initial proposed no significant hazards consideration determination.
The current TS at HBR were implemented prior to the development and issuance of NUREG-0452, Revision 3, "Standard Technical Specifications for Westinghouse Pressurized Water Reactors," dated Fall 1981.
As such, many of the operator actions specified in NUREG-0452 for inoperable equipment were not contained in the HBR TS. The proposed changes will upgrade the RTS, ESFAS, and isolation function instrumentation to more closely agree with NUREG-0452, Revision 3.
Currently, the TS Section 3.5.1 and Tables 3.5-2, 3, and 4 do not specify discrete operator actions whenever an instrument channel becomes inoperable and do not clearly define the applicability for each functional unit.
2.0 EVALUATION The current TS Section 3.5.1 and Tables 3.5-2, 3, and 4 describe the limiting condition during which RTS and ESFAS instrumentation may be inoperable. The TS section requires that when the number of channels of a particular subsystem in service falls below the limits given in the table columns entitled "Minimum Operable Channels," or the "Minimum Degree of Redundancy" cannot be achieved, operation shall be limited according to the requirement shown in column 3 of the tables. The proposed changes make editorial enhancements, delineate discrete actions whenever an instrument channel becomes inoperable, and add an "Applicable Conditions" column that defines the applicability and/or mode of operation of each functional unit.

-2 The NRC staff has reviewed the proposed changes and has concluded that the changes are acceptable because they clarify the applicability of RT and ESFAS requirements and agree with the action statements described in NUREG-0452, Revision 3.
The NRC staff finds the proposed changes, therefore, acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the State of South Carolina official was notified of the proposed issuance of the amendment.
The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC 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 cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (61 FR 5812). Accordingly, the 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 environmental assessment need be prepared in connection with the issuance of the amendment.
5.0 CONCLUSION
The Commission 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, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
