PT-20.5 Integrated Primary Containment Leak Rate Test (IPCLRT). Of particular concern was meeting the test requirements of 10 CFR Part 50 Appendix J for proper venting and draining of systems and meeting the acceptance criteria of Appendix J BN-TOP-1, and ANS-4 , Periodic Test PT-20.5 meets these requirements and acceptance criteri Violation Item 325/81-13-01 a close ' (Closed) Unresolved Item 325/81-13-02, Review of the June 1981 Unit 1 t Type A Test Results. The Type A test is considered a failed test  : because it did not meet the acceptance criteria in Appendix J Paragraph III. A.1(a), which states that during the performance of the l test no repairs or adjustments shall be made so that the containment l can be tested in as close to the "as is" condition as possibl The licensee identified and isolated a leakage path through the CAC system  ; after the test was starte Since this constituted an adjustment to  : the containment, subsequent to the inspection, the Itcensee determined i this was a fatted test. Unresolved Item 325/81-13-01 is close , (Closed) Unresolved item 325, 324/85-21-01, Complete Review of LLRT Valve Alignments to Determine if Procedure is Adequate. The inspectors I reviewed Engineering Procedure: ENP-16.4 Use of Local Leak Rate Test i Equipment and 121 periodic tests: (PT-20.3.54-PT-20.3.175) local Leak  ; Rate Test for Containment Isolation. The valve alignments in all the procedures reviewed were in the proper test position and a vent path r for each penetration was estabit sbed. The valves tested in the reverse i (Non-LOCA) direction were identified in CP&L letter, serial i number: BSEP/84-161 This letter is addressed in paragraph 5. I Unresolved Item 325, 324/82-21-01 is close ! i (Closed) Unresolved Item 32S, 324/82-38-01, Verify Testing of Isolation I Valves in the Reverse Direction is Conservative. The licensee has i committed to preparing a report to NRR including an evaluation and i justification for testing isolation valves in the reverse (Non-LOCA) l direction. This item is addressed in paragraph 7.c. Unresolved Item ' 325, 324/82-38-01 is closed, r Unresolved Items i Unresolved items were not identified during this inspectio .

The inspectors examined Type C local leak rate testing procedures and the local leak rate test apparatus. During review of the procedure t, the  ! inspectors determined which valves were tested in the reverse direction, and verified that the identification of these valves was documented. Acceptance criteria utilized by the inspectors appear in 10 CFR 50 Appendix . i

, i a. Local Leak Rate Test Apparatus i l The inspectors reviewed the construction of the licensee's local leak i j rate test apparatus with the following observations-

       '

! '

 (1) The flow meters on the test rig were within the range for normally  ;

expected valve leakag ' l l (2) A potential leakage path (via valve V-8) exists such that high j pressure make-up could bypass the flow meters during the t performance of local leak rate testin This would result in a j nonconservative leak rate calculatio The licensee will review j the construction of the test apparatus and make adjustments if

appropriat I j (3) The test apparatus employs the upstream test method which will i detect seat, stem and packing leakage (except as noted in section j on valves tested in the non-LOCA direction).

 (3) Globe Valves. These globe valves are pressurized from beneath the  i disc during the local leak rate test. This is a more conservative  l j  direction because test pressure would try to lif t the disc from its seat. However, testing from this direction leaves the packing  >

Two globe valves, numbers E11-F027A and E11-F0278 are installed in l

{ lines open to primary containment atmosphere and would require i J extensive modification to test in the LOCA direction. Since the  ! packing on these valves is normally exposed to drywell pressure , only and the valve is cycled only for testing, total packing , l failure is unlikely. An additional conservatism is that LLRTs are  ; j conducted by pressurizing between the two isolation valve ;

. 10 Type A Test Sequence and Description (61719) (90713) Pressurization of containment commenced at 2049 hours on September 23, 198 At 2230 hours the Personnel Airlock outer door seal was found to be leakin The seal was repaired at 0305 hours on September 24 and pressurization continue Containment test pressure was attained at 0511 hours on September 24, 1985, at which time the stabilization period bega During pressurization, stabilization and the next several hours an extensive leakage investigation revealed only minor seat or packing leakage on the following valves: E41 - F012 Ell - F027A At 1130 hours on September 24, 1985, the licensee met the containment stabilization criteria as established in BN-TOP-1 1972 Revision 1, Section 2.3.A.1, which states: "The 4 rate of change of average temperature is less than 1.0 F/ hour averaged ohr the last two hours".

At 1200 hours on September 24, 1985 the licensee began the ILRT. The reactor vessel level had been dropping at approximately 0.6 inches per hour, at 1435 hours the Control Rud Drive cooling water pumps were isolated in an attempt to stop the leakage. The leak continued and the licensee sub-sequently determined that the leakage path was into containment and would not effect the test results. At 1610 hours on September 24, 1985, the licensee halted the test and increased the reactor vessel leves to 211 inche The test was restarted at 1645 hours on September 24, 198 At 0600 hours on September 25, 1985, the ILRT met all the acceptance criteria established in BN-TOP-1 Section 2.3.8, for test termination as noted below: Criteria The trend report based on total time calculations was less than miximum leakage rate allowable (Note: BN-TOP-1 Section 2.3.B.1, indicated the maximum allowable leakage is L However, 10 CFR 50 Appendix J, which was issued subsequent to BN-TOP-1, reduces this to 0.75La. In cases where there is conflict between test methods and the regulations, the regulations govern).

Seventy-five percent of the maximum allowable leakage rate (0.75 La) for Unit 1 is 0.375 % weight / day. The preliminary test results indicated the leakage rate calculated to be 0.3635% weight / day which was obtained by adding the Type C penalty of 0.008*. weight / day to the mea >ured leak rate of 0.3555*. weight / da Criteria The end of the test upper confidence limit for the calculated leak rate based on total time was less than 0.75La (note discussion in Criteria B.1) including the as-found leakage and the type B and C leakage penaltie . - . -. - . . . _ _ - _ - . .- - .- . _ . - . _ ._. _ _ - _ _ - _ - - . _ l i

Miscellaneous leakages, not identified or quantified during Type C testing, were identified while performing the Type A testing.

In a letter to NRC Region II, serial number: 85EP/82-1988, the licensee performed a review and has taken or committed to corrective actions to quantify or eliminate these leakage path IFI 325, 324/82-21-02 is close (Closed) IFI 325, 324/82-38-02, Changes to Pipe Supports and Restraints.

(Closed) IFI 324, 325/84-28-01 Review of the September 1984 Unit 2 Type A Test Results and the Licensee's Proposed Test Schedule. The Type A test is considered a failed test becuase it did not meet the acceptance criteria in Appendix J paragraph III. A.1.(a), which states that during the performance of the test no repairs or adjustments shall be made so that the containment can be tested in as close to the "as is" condition as possible. The licensee identified and isolated a water leak path from the RHR pump suction and discharge lires to the RH4 sump through 4-inch drain valves. This failure was the third consecutive Unit 2 Type A failure. The licensee acknowledged that the subsequent test dates must be in accordance with Appendix J paragraph III.A.6.(b) which states that if two consecutive Type A tests fail to meet the applicable test criteria, a Type A test shall be performed at each plant shutdown for refueling or approximately every 18 months, whichever occurs first, until two consecutive Type A tests meet the acceptance criteria.
