SAFETY EVALUATION AMEND)1 t N

C S A UN, UNIT 1 C

N Introduction The licensee proposed an amendment to license condition 2.C.(9) to the operating license for Susquehanna Steam Electric Station, Unit 1 to utilize the Susquehanna Final Safety Analysis Report (FSAR), as amended through Amendment 49 to conduct the post-fuel-loading initial test program as set forth in Section 14 of the Susquehanna FSAR.

Evaluation In Amendment 49 to the FSAR, Section 14, the licensee revised the "Shutdown from Outside the Main Control Room" test description to state that the test would be initiated by a reactor trip and main steam isolation valve (MSIV) closure from within the control room.

The staff position, as stated in Regulatory Guide 1.68.2, is that the hot shutdown demonstration portion of the test including all initiating actions, be accomplished from outside the control room.

While tripping the reactor, and shutting of NSIV's prior to control room evacuation may be a more likely and realistic event, and is consistent with written emergency procedures, the emergency procedures include alternate instructions for tripping the reactor and shutting the tlSIVs from outside the control room.

The staff positfon is that testing should be performed to demonstrate the capability to perform these actions from outside the control room.

In a letter, dated August 26, 1982, the licensee committed to modify start-up test procedure ST-28, "Shutdown from Outside the Main Control Room" to include verifying that the r eactor can be scrammed and the MSIVs can be closed from outsfde the main control room.

On this basis, the staff finds the requested changes in Amendment 49 to Section 14 of the FSAR consistent with the criter ia in the Standard Review Plan, Section 14.2.

Amendment 50 to the Susquehanna FSAR was provided by PP&L letter, dated Duly 13, 1982.

Amendment 50 made no changes to Section 14 of the FSAR, but is incorporated into the amended license condition 2.C.(9) for administrative purposes only.

Therefore, the change to license condition 2.C.(9) to the operating license for Susquehanna Steam Electric Station, Unit 1, to utilize the Susquehanna FSAR, as amended through Amendment 50 is accceptable.

Environmental Consideration He have determined that this amendment does not authorize a change in effluent types or total amount nor an increase in power level and will not result in any significant environmental impact.

Having made this determination, we have further concluded that this amendment involves action which is insignificant from the standpoint of environmental impact, and, pursuant to 10 CFR Section 51.5(d)(4), that an environmental impact statement or negative declaration and environmental impact appraisal need not be prepared in connection with the issuance of thi s statement.

Conclusion He have concluded, based on the considerations discussed above, that:

(1) because the amend[vent does not involve a significant increase in the probability or consequences of accidents previously considered, does not create the possibility of an accident of a type different from any evaluated previously, and does not involve a significant decrease in a safety margin, the amendment, does not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be endanagered by operation in the proposed

manner, and (3) 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.
