UNITED STATES NUCLEAR REGULATORY COMMISSION PENNSYLVANIA POWER & LIGHT COMPANY ALLEGHENY ELECTRIC. COOPERATIVE, INC.
DOCKET NO. 50-387 NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE AND PROPOSED N0 SIGNIFICANT HAZARDS qg CONSIDERATION DETERMINATION AND OPPORTUNITY FOR HEARING The U. S. Nuclear Regulatory Commission (the Commission) is ccnsidering issuance of an amendment to Facility Operating License No. NPF-14, issued Lto Pennsylvania Power &. Light Company and Allegheny Electric Cooperative, Inc.
(the licensees), for operation of the Susquehanna Steam Electric Station, Unit 1 located. in Luzerne County, Pennsylvania.
The amendment would change Technical Specification Table 4.8.1.1.2-2 to
'nodify the start time sequence of two Emergency Service Water (ESW) pumps from 53 and 57. seconds to 44 and 48 seconds, respectively, in accordance'with the
-licensee's application for an amendment dated October 20, 1983, as modified by licensee letter dated November 7,1983.
The change is proposed to support two unit operation and prevent the potential concurrent starts of the Residual c.
Heat Renoval (RHR) or Core Spray.(CS) pumps with.the ESW pumps 'due to incorporation of the low vessel pressure interlocks required on the RHR and CS pump initiation signals in order to prevent a LOCA - false LOCA condition during two unit operation.

Before. issuance of the proposed license amendment, the Commission will have made findings required by the Atcmic Energy Act of 1954, as arended (the Act) and the Commission's regulations.
The Commission has made a proposed determination that the amendment request involves' no significant hazards ccnsideration.
Under the Commission's regulations in 10 CFR 50.92, this means that operation of the facility in accordance with the prepcsed amendment would_ not (1)-involve a significant increase in the probability or conscquences_ of an accident previcusly evaluated; j
or (2) create the_ possibility of a new or different kind of accident from any' accident previcusly evaluated; or (3) involve a significant reduction in a
- rargin of safety.
- The licensee in his letter of October 20, 1983, stated thaf'the propese'd
-change does not involve a significant increase in the probability or con-spquences of an accident previously evaluated.
The licensee has-re-evaluated the twu' unit diesel generator load sequence study 'and the two unit offsite pcuer supply voltage study and stated that the~ studies are not affected by the
-proposed' change.
The ESW pump start time sequence was previously changed to the current values in order to stagger start the pumps to mitigate. water effects in the system.
The licensee believes the effects of water hammer willJ be mitigated by the proposed action.
The licensee stated that the proposed change does. not create the possibility of a new or different kind of accident frcm any-accident previously evaluated because each area of potential concern has been determined to be within the constraints of previous design and safety.
analyses.
The licensee also stated that the proposed change does not involve d
-,N (7590-01) a significant.' reduction in a margin of safety because the.two unit offsite power supply voltage study and the two unit diesel genera' tor lcad sequence study are not adversely affected by the proposed change, water hammer loads are minimized by-the prcposed chang'e, and no other margin of safety as defined in the basis for any other Technical Specification is adversely affected by the proposed change. The staff agrees with the licensee's evaluation, in this regard and, accordingly, the NRC staff proposes to find that the amendment request involves no significant hazards consideration.
g The Commission has determined that failure to act in a timely way would result in delaying the startup of Unit 1 follcwing the tie-in outage for Unit 2 and delaying the fuel load of Unit 2.
Therefore the Commission has
. insufficient time to issue its usual 30-day notice of the propcsed action
'for public' comment.
If the proposed determination becomes final, an opportunity for a-hearing will be published in the Federal Register at a later date and any hearing request will not delay the effective date of th& amendment.
If the Conmission decides in its final determination that the amendment does involve a significant hazards consideration, a notice of opportunity for.a prior hearing will be published in the Federal Register-and, if a hearing is granted, it will be held before any amendment is issued.
