.c SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AltENDitENT NOS. 132 AND 8 TO FACILITY OPERATING LICENSE N05. DPR-66 AND NPF-73 DUQUESNE LIGHT COMPANY OHIO EDISON COMPAln PENN5YLVANIA POWER COMPANY THE CLEVELAhD ELECTRIC ILLUMINATING COMPANY THE TOLEDO EDI5ON COMPANY BEAVER VALLEY POWER STATION, UNITS 1 AND 2 DOCKET N05. 50-334 AND 50-412 INTP000CT10N By letter dated June 22, 1988 Duquesne Light Company (the licensee, acting as agent for the above-listed utilities), requested changes to the Technical Specifications (TS) of Beaver Valley Power Station, Units 1 and 2 to correct certain errors and inconsistences. We have evaluated the application as follows.
DISCUSSION AND EVALUATION (1) Table 4.3.1, "Reactor Trip System Instrumentation Surveillance Requirerents" (botn units)
As previously written, a non-cor.servatism existed in Table 4.3-1.
Table 3.3-1 requires the source range trip channels tu be operable in Modes 2 (below P-6),
3, 4 and 5.
However, Table 4.3-1 only required source range trip channels surveillance in Modes 2 3 4 and 5 with the reactor trip breakers closed.
This impliedthatnosurveillanc,ewasrequiredonthesourcerangechannelswith the reactor trip breakers open.
The channel operability requirement with the reactor trip breakers open ensures that the source range channels are operable for protection against RCS boron dilution events.
To remove the non-conservatism, the licensee proposed to eliminate the qualifying statement regarding MoJes 3, 4 and 5 such that survei1~ance of the source range channels will be performed regardless of the position of the reactor trip breakers.
This administrative change makes tie subject specification store cunservative and is thus acceptable.

2-(2) Specification 3.1.3.3 Regarding Rod Position Indication (Unit 2 only)
The ACTION statement contains a typographical error: "group demand" should be "digital roo".
The error was introduced when the Unit 2 TS was written by modifying the Unit 1 TS; "group demand" correctly reflects the Unit 1 design but is incorrect for Unit 2.
TP. proposed correction of the error is acceptable.
l (3) Pege 3/4 3-6 (Unit 2 only)
ACTION 5 should read "... 2CHS-91 is...." instead of "... 2CHS-91 are....".
The correction is editorial and is acceptable.
ENVIRONPENTAL CONS 10ERATION These amendments change surveillance requirements and make editorial changes.
The staff has determined that the amendments involve 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 indivioual or cumulative occupational radiation exposure. The staff has previously issued i
a proposed finding that these amendments involve no significant hazat ds e asidera-i j
tion and there has been no public coment on such finding. Accordingly, these amendments Etet the eligibility criteria for Categorical exclusion set forth in 10 CFR 51.22(c)(9) and (10).
Pursuant to 10 CFR 51.22(b) no environmental impact statemeitt or environmental assessment need be prepared in connection with j
j the issuance of these amendments.
CONCLUSION 1
We have 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 corrpliance with the Conunission's regulations, and (3) the issuance of these amendments will net be inimical to the comon defense and security or to the health and safety of the public, i
