          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 Outages.
                      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. This item will remain open.

                      -

              -
                    Technical Specification 4.7.A.f
        3.2 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 containment.
        3.3 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 requirements.
              The procedural valve lineups and associated instructions were ade-
              quate to allow for the proper venting and draining of test boundaries.
              No unacceptable conditions were identified.
        3.4 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 identified.
        3.5 LLRT Test Box Calibration
              The inspectors witnessed the calibration of two local leak rate test
              boxes.  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 identified.
        3.6 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 licensee.
              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
              only.  During non-CILRT outages, the licensee uses a different method

                    conditions were identified.
        .4.0 . Containment Integrated Leak Rate Test (CILRT)
              4.1 Documents Reviewed
                    -
                          Surveillance Test Procedure ST-12.5-1,. Revision 5, Integrated
                          Leak Rate Tes' draft version

                    -
                          CILRT Volume Fraction Calculation
              4.2 Scope of Review
                    The inspectors reviewed the above listed documents for technical
                    adequacy and to determine compliance with requirements of technical
                    specifications,10 CFR 50, Appendix J, and applicable industry
                    standards.
              4.3 Procedure Review
                    ILRT Procedure ST-12.5-1, Revision 5, was reviewed in its present
                    draft stage. The final version is also planned to be reviewed by
                    the inspectors prior to the upcoming ILRT.
              4.4 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 test.    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 time.
      5.0 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

          6.0 Facility Tours
              The inspectors made several tours of the facility including the control
              room, turbine floor and secondary containment. General housekeeping of
              the facility was good. No unacceptable conditions were identified.
        7.0 Exit-Meeting
              A meeting was held on October 4, 1985, to discuss the scope and findings
              of the inspection as described in this report (see Section 1 for
              attendees). At no time during the inspection were written inspection
              findings provided to the licensee.
