ATTACHMENT TO LER 79-13 Revision 1 Event Descri tion and Probable Conse uences During refuel outage, three Instrument Surveillance Procedures, Nl-ISP-

.25.3, Containment Spray/Raw llater Heat Exchanger Leak Rate Test, Nl-ISP-24.2, Type B Leak Rate Test Drywell Mechanical Per Double Gasket, Nl-ISP-25.2, Primary Containment Isolation Leak Rate Tests, were implemented before the requi red temporary procedure-change signatures were obtained. Also, Nl-ISP-25.3 and-Nl-ISP-24.2 were not reviewed by the Site Operations Review Committee within the required seven days.

Since no violations of approved Operating Procedures were involved and knowledgeable Senior Reactor Operators were consulted in each case, there were minimal safety implications as a result of these instances.

Cause Descri tion and Corrective Actions Review of the temporary changes indiciated in this report has been made by authorized personnel and subsequent approvals have been obtained from supervisors who should have documented the approvals at the time of im-plementation. Regular procedure changes have been reviewed by the Site Operations Review Committee and approved by the General Superintendent Nuclear Generation.
