dated September 12, 1984 j
Gentlemen.
l The referenced letter committed that eight of s'ixteen-leakage reduction surveillance tests to be performed to satisfy the program described in the Limerick-Generating Station (LGS) Final' Safety Analysis Report (FSAR).Section 6.2.8 would be
-completed prior to fuel load for each unit and that the results would be submitted for your review. Attachments 2 and 3 provide the surveillance ~ test results for Unit 2 as total system leakage and for each component, respectively.. The Scram Discharge Volume Contaminated Piping Inspection procedure, ST-1-047-700-2,.will be performed
-)
again when the system is pressurized to operating reactor pressure prior to initial criticality.
'I i
The remaining eight surveillance test procedures will be completed after fuel load and the test results will be submitted in accordance with the schedule provided in the referenced letter. Leakage limits will be established after all l
sixteen surveillance tests (See Attachment'1) have been completed.
