SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 1 TO FACILITY OPERATING LICENSE NO. DPR-75 PUBLIC SERVICE ELECTRIC AND GAS COMPANY, PHILADELPHIA ELECTRIC COMPANY, DELMARVA POWER AND LIGHT COMPANY, AND ATLANTIC CITY ELECTRIC COMPANY SALEM NUCLEAR GENERATING STATION, UNIT N0. 2 DOCKET N0. 50-311 The proposed Technical Specificatior change provides that during control rod drop measurements, testing, and position indication calibration, either the rod position indicator is operable during withdrawal of the rods or k-effective is maintained less than er equal to 0.95.
This applies in Modes 3, 4, and 5.
The change consists of ddition of control rod testing and position indication calibration and maintaining k-effective less than or equal to 0.95.
The original purpose of the specification was to ensure that the position of the rods being moved was known, in order to preclude the remote possibility that the reactor inadvertently would be made critical.
Substitution of the require-ment that k-effective is maintained less than or equal to 0.95 is also an acceptable method for avoiding inadvertent criticality of the rector.
This criterion is one of the options specified for refueling (to avoid inadvertent criticality).
We therefore find the proposed Technical Specification change will have no adverse effect on the safety of the power plant, and is acceptable.
Environmental Consideration We have determined that the amendment does not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact. Having made this determination, we have further concluded that the amendment involves an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR 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 this
. amendment.

2-Conclusion We have concluded, based on the considerations discussed above, that:
(1) because the amendment does not involve a significant increase in the probability or consequences of accidents previously considered 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 endangered by operation in the proposed manner, and (3) such activities will be con-ducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the connon defense and security or to the health and safety of the pubitc.
