SUMMARY

OF CHANGES, TESTS, AND EXPERIMENTS FOR THE SALEM UNIT 2 GENERATING STATION MONTH: August 1999 The following items completed during August 1999 have been evaluated to determine:

1. If the probability of occurrence or the consequences of an accident or malfunction of equipment important to safety previously evaluated in the safety analysis report may be increased; or

2. If a possibility for an accident or malfunction of a different type than any evaluated previously in the safety analysis report may be created; or

3. If the margin of safety as defined in the basis for any technical specification is reduced.

The 10CFR50.59 Safety Evaluations showed that these items did not create a new safety hazard to the plant; nor did they affect the safe shutdown of the reactor. These items did not change the plant effluent releases and did not alter the existing environmental impact. The 10CFR50.59 Safety Evaluations determined that no unreviewed safety or environmental questions are involved.

Design Changes - Summary of Safety Evaluations Modification 2EC-3654, Pkg. 1, Auxiliary Annunciator (AAS) Replacement Project This modification implemented design changes to the AAS to address Year 2000 concerns. The modification included replacement of Rochester Instrument Systems (RIS) 3800 series equipment and replacement of an existing typewriter/printer unit.

Review of this modification under 10CFR50.59 was required because the replacement of the AAS equipment constituted a change to the facility as described in the UFSAR. This evaluation concluded that this change would not increase the probability or consequences of an accident previously analyzed.

Additionally, this change did not increase the probability or consequences of a malfunction of equipment important to safety. This change would not create any new accidents or malfunctions since no new failure modes were introduced. In addition the Technical Specification Bases were not affected and no changes to the Technical Specifications were required.

Temporary Modifications - Summary of Safety Evaluations There were no changes in this category implemented during August 1999.

Procedures - Summary of Safety Evaluations There were no changes in this category implemented during August 1999.

UFSAR Change Notices - Summary of Safety Evaluations UFSAR Change Notice SCN99-048, Reactor Coolant System Chemical Degassing Operation During Shutdown This UFSAR change involved the addition of hydrogen peroxide to the Reactor Coolant System (RCS) following plant shutdown and cooldown for the purpose of chemically depleting RCS dissolved hydrogen inventory. Chemical degassing will occur only in operational Mode 5 and below.

Review of this temporary modification under 10CFRS0.59 was required because chemical degassing of the RCS constituted a change to the facility as described in the UFSAR and constituted a change to procedures as described in the UFSAR. The evaluation concluded that this change would not increase the probability or consequences of an accident previously analyzed. Additionally, this change did not increase the probability or consequences of a malfunction of equipment important to safety. This change would not create any new accidents or malfunctions since no new failure modes were introduced. In addition the Technical Specification Bases were not affected and no changes to the Technical Specifications were required.

Deficiency Reports - Summary of Safety Evaluations There were no changes in this category implemented during August 19~9.

Other - Summary of Safety Evaluations There were no changes in this category implemented during August 1999.
