2.0 Licensee Action on Previous NRC Findings 2.1 (0 pen) Inspector Follow-up Item (50-278/86-10-01): Licensee Not Performing Type B and C Testing Results Comparison to 0.6 La for As-found Condition During Non-CILRT Outage This item dealt with the method of recording the results for type B and C leakage tests. The method used by the licensee now masks the running total for the LLRT criteria. The licensee agrees with the inspectors' concern, but as of this inspection, has not made any changes.

Technical Specification 4.7. .2 Scope of Review The inspectors reviewed the above listed documents to determine compliance with the regulatory requirements of 10 CFR 50, Appendix J, technical specifications and applicable industry standards. The inspectors held discussions with the licensee regarding the documen-tation of test results, the repair and retesting following failed tests, and the relationship of these items to the "as-found" and

"as-left" conditions of the containmen .3 LLRT Procedure Review The inspectors reviewed specific LLRT procedures being used during the current outage. These procedures were determined to be techni-cally accurate and in conformance with the regulatory requirement The procedural valve lineups and associated instructions were ade-quate to allow for the proper venting and draining of test boundarie No unacceptable conditions were identifie .4 LLRT Instrumentation Calibration Records The inspectors reviewed the calibration records for the pressure gages and rotameters in the LLRT test boxes. The calibrations were current. The standards used also had current calibration and were traceable to the National Bureau of Standards. No unacceptable *

conditions were identifie .5 LLRT Test Box Calibration The inspectors witnessed the calibration of two local leak rate test boxe The test personnel were familiar with the test equipment and the use of the procedure. The calibration was conducted in accord-ance with an approved procedure (RT 7.0, Revision 5). The inspectors verified the documentation of the test result. No unacceptable conditions were identifie .6 LLRT Test Results Evaluation The inspectors reviewed individual LLRT results and the running leakage total. The inspectors also discussed analysis of the test results and the status of repairs and retests with the license All "as-found" and "as-left" local leak rates are individually item-ized and incorporated into two running totals, one "as-found" and one "as-left." This documentation method is being used for CILRT onl During non-CILRT outages, the licensee uses a different method

The final version is also planned to be reviewed by the inspectors prior to the upcoming ILR .4 CILRT Instrumentation The inspectors reviewed the ISG calculation. It was.found to be appropriate only for the case where all instrumentation is operable for the duration of the test. 'It is possible to have one or more sensors (total pressure, drybulb and dewpoint temperature) fail during the tes In this case, to meet ISG criteria, the test will have to be run for a longer duration. The licensee agreed to include an instrument failure analysis in their calculation. The inspectors had no further questions at this tim .0 QA/QC Involvement in LLRT and CILRT .

LLRT and CILRT activities are monitored by plant QC personnel. QC selects a sample of LLRT's to be monitored from the outage schedule. These LLRT's are then reviewed in accordance with a " Detailed Monitoring Checklist" (DMC) which is' specific to the type of test being performed. The CILRT is also monitored with a DMC which is specific to the CILRT procedures. The DMC's were found to be comprehensive and technically useful from a QA/QC
