10 CFR Part 50, Appendix J; ANS N45.4-1972; Bechtel Topical' Report BN-TOP-1,~ Revision 1; and ANSI /ANS 56.8-1981 requirements. The inspector's' comments were discussed with the applicant prior.to the issuance"of Revision ~1 to the procedure. With the exception of the '
below open items and deviation, the.CILRT procedure was adequate for the preoperational CILR During the performance of the Type A test, the inspector noted the CILRT procedure'did not require the trending-of sensors throughout the test as the testing methodology they were using (BN-TOP-1)
required. The applicant trended the sensors, at the inspector's suggestion, throughout the test duration, as per requirements. This is considered an open item-(461/85060-01(DRS)) pending the inspector's review of the procedure prior to the performance of the next Type A tes Additionally, the inspector noted that after the successful Type A measured leakage phase of the test, test personnel following the procedure would have terminated the verification test at four hours, if the inspector had not informed them of the BN-TOP-1 requirement for running the verification test for half the duration of the Type A test (9.25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> /2). The inclusion of this requirement into the procedure's acceptance criterion will be tracked as an open item (461/85060-02(DRS)).
During several of the discussions with the applicant pertaining
'to the inspector's CILRT procedure review, the inspector noted to the applicant that the procedure appeared to call for the use of a shortened test methodology (less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />), as described in Bechtel Topical Report BN-TOP-1. The inspector inquired where the applicant had committed to perform the BN-TOP-1 short duration test methodology; as generally, plants that use the BN-TOP-1 method for preoperational tests request specific permission from the office of Nuclear Reactor Regulation to do so. The applicant stated they had committed to perform this methodology in the CILRT procedure. WI.ile reviewing Clinton's Final Safety Analysis Report, the inspector noted that FSAR Chapter 6.2.6.1 states, in part, that Containment Integrated Leak Rate Tests (CILRT) will be performed in accordance with the-requirements for Type A test outlined in ANS N45.4. Additional guidelines will be extracted from ANSI /ANS 56.8. ANS N45.4-1972 is endorsed by the NRC and is the standard referenced in 10 CFR Part 50, Appendix J for the express. purpose of performing the CILRT or Type A tes Additionally, ANS N45.4 requires that Type A tests be of 24-hour duration. ANSI /ANS 56.8-1981 has not been endorsed by the NR The performance of the preoperation CILRT of less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> using the Bechtel Topical Report, BN-TOP-1, is in direct conflict with the FSAR commitment to ANS N45.4 for a 24-hour tes Failure by the applicant to perform the Type A test in accordance with the FSAR is considered a deviation from a commitment (461/85060-03(DRS)).

In addition to matters discussed elsewhere in this report, the following requirements of Appendix J and Bechtel Topical Report, BN-TOP-1 were discussed in reference to Type A, B and C testing with
' the applicant to ensure a common understanding of the regulations:
(1) Whenever penetration configurations during a CILRT deviate from the ideal, the results of LLRTs for such penetrations must be added as a penalty to the CILRT results at the 95% ccnfidence level. This penetration leakage penalty is determined using the." minimum pathway leakage" methodology. This methodology is defined as the minimum leakage value that can be quantified through a penetration leakage path (e.g. , the smallest leakage of two valves in series). This assumes no single active failure of redundant leakage barriers. Additionally, aryy increase in containment sump, fuel pool, reactor water,'or ,
suppression pool level during the course of the CILRT must be taken as a penalty to the CILRT result If penalties exist, they must be added (subtraction is never permitted) to the j upper confidence level of the CILRT result (2) The Type A test length must be 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or longer to use the mass point method of data reduction. If tests of less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> are planned, the Bechtel Topical Report, BN-TOP-1, must be followed in its entirety, including the trending of sensors, except for any section which conflicts with Aapendix J requirements. For either methodology, the acceptance t:riterion is that the measured leakage at the 95% upper confident:e limit
, must be less than 75% of the maximur allowable leak rate for the pressure at which the test was performe (3) For the supplemental test, the size of the superimposed leak rate must be between 0.75 and 1.25 times the maximum allowable leak rate La. The higher the value, the bette The supplemental test must be of sufficient duration to demonstrate the accuracy of the tes The NRC looks for the results to stabilize within the acceptance criteria, rather than the results being within the acceptance criteria. Whenever the BN-TOP-1 methodology is being used, the length of the supplemental test cannot be less than approximately one-half the length of the CILR (4) An acceptable method for determining if the sum of Type B and C test exceeds the 0.60 La Appendix J limit is to utilize the
" maximum pathway leakage" method. This methodology is defined as the maximum leakage valve that can be qualified through l t penetration leakage path (e.g., the larger, not total, leakage of two valves in series). This assumes a single active failure to the better of two leakage barriers in series when performing Type B or C test (5) Future periodic Type A, B, and C tests must include both as found and as left results. In order to perform Type B and C test rerairs prior to a Type A test, an exemption from

Data rejection criteria should be developed and used so that tne applicant would have a consistent, technical basir. for data rejection. One example of an acceptable method for data outliers is described in an appendix to ANSI /ANS 56.8-1981. Sensor data rejection criteria should be plant specific and based upon a sensor's trend relative to the average scatter, slope, and/or absolute output of the senso ' Local Leak Rate Tes_t Procedure (s) Review >

Revision 1, entitled Local Leak Rate Tests, for Conformance with Regulatory Requirements and ANSI /ANS 56.8, which the applicant had committed to. The main body of the procedure appeared to be technically adequate and concis The appendices of the procedure which not!ir.cd specific tests on the different penetrations wsre eumned on a sampling basis and as such, approximately 25% were reviewed. While the,ir ector noted a large number of exceptions and discrepancies, the ppendices were generally well written and accurat ,
One section of each appendix that was deleted in Revision 1 to the procedure was the isometric of each penetration. The inspector felt inclusion of the isometrics would be helpful for future local leak rate test No violations or additional deviations were identifie . PrSoperatjona_1_

_ Instrumentation The inspector reviewed the calibration data and verified that all of the instruments used in the test had been calibrated and that the correct weightings were placed into the computer program as required. The inspector noted the relatively good quality of the data, but also noted the small number of instruments in the containment, specifically the drywell . The inspector recommended the number of sensors in the drywell be, as a minimum, doubled for the first periodic Tyse A test to better monitor the heat loads in the drywell that were not present for the preoperational test. No sensors or data sets were rejected during the Type A tes _

The following instrumentation was used during the test:
Type Quantity Resistance Temperature Detectors 22 Humidity Sensors 9 fi Pressure Manometers 2 Rotameters 2 b. Pretest Requirements The inspector performed a pretest containment inspection, including the drywell, to ensure the proper placement of test instrumentatio Prior-to this inspection, the applicant noted several humidity sensors that became saturated during containment depressurization from the Structural Integrity Test (SIT). The inspector witnessed the applicant's inspection of several of the sensors, along with the drying of one sensor with bottled nitrogen. Overall, the placement and number of test instrumentation was adequate for the preoperational CILRT due to the lack of heat load The applicant had performed a containment liner inspection as required bysAppendix J prior to the performance of the CILRT. The subsequent discovery of a hole in the containment ~ liner 16 days after the performance of the CILRT puts the adequacy of the applicant's liner inspection in questio Details regarding the hole and the applicant's inspection are contained in Section 7.a of this repor The inspector witnessed the pressurization of containment for the CILRT, and verified that additional procedural prerequisites had been satisfied as noted by the applicant's procedural sign-off c. Valve Lineup Verification To ensure that no fluid could enter the containment atmosphere and

Test Witnessing Upon completion of the SIT, the applicant kept the containment at a pressure that was 85% of the Type A test pressure for a duration of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> as required by ANS/ ANSI 56.8-1981. Subsequently, the applicant repressurized containment and was at test pressure at 5:45 p.m. on December 31, 1985. Upon the satisfactory completion of the required stabilization period, the applicant began the measured leakage phase of the test at 10:00 p.m. that evening. After the successful completion of the 9.25 hour2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> short duration test, the applicant imposed a leak and began the verification portion of the te:;t at 8:30 a.m. on January 1,1986. The supplemental verification test was declared successful after five hours with acceptable agreement between the predicted and ;neasured leakage rat No violations or deviations were identifie . CILRT Da_ta Evaluation Measured Phase Data Evaluation -
The short duration CILRT was performed with data being co!!ccted and reduced by the applicant every 15 minutes. The inspector independently" monitored and evaluated leak rate data using the Bechtel Topical Report, BN-TOP-1, Revision 1, total time formulas to verify the applicant's calculations of the leak rate. There was acceptable agreement between the results of the inspector and applicant as indicated by the following sumary (units are in weight percent per day):

- - Local Leak Rate Testing had not been completed for these area After taking these local penalties into account, the upper confidence value for containment leakage is equal to 0.298 weight percent / day, still well within the acceptable value of 0.4875. While all of the leakage penalties have not been calculated to date (denoted by *),
it is not anticipated that these vaiues will have a marked effect on the containment leakage rate. However, it is the applicant's responsibility to ensure the results of any local leak rate tests (LLRTs) that are performed between the CILRT and plant operation and the two remaining tests required above do not cause the containment to leak _ in excess '? the allowable leak rate prior to the plant requiring containment integrit _

Drywell Bypass Test Results Review After the completion of the CILRT, the applicant performed the required Low Pressure Bypass Leakage Rate Test on the drywell structur The test consisted of the pressurization of the drywell to above 3 psig and measuring the leak rate of the drywell structur The inspector reviewed the results of this test to determine if the applicant met the Technical Specification (TS) limit of 3600 SCFM at the above test condition The resultant leakage rate measured by the applicant was approximately 275 SCFM, well below the TS allowable of 3600 SCF No violations er deviations were identifie . Review of Work on Containment Liner In previous discussions with the applicant, the inspector stated that after the performance of the SIT and CILRT, work on the containment liner should be controlled in'such a manner as to not invalidate the SIT or CILRT results. To make a determination as to the adequacy of the applicant's control of work performed on the containment liner, L.he inspector looked at three different areas. The first area centered around the discovery of a hole in the containment liner. The second entailed a direct inspection of the containment liner to identify work performed on tht liner since the CILRT. The third consisted of the quantification of the work on the liner and inside the containmen Followup of Events Surrounding Discovery of a Hole in the Liner On January 18, 1986, a hole through the liner of dimensions 7/8 x 1/2 inch was discovered by a Quality Assurance representative who was performing an inspection of a nearby area where a temporary attachment had recently been removed. The inspector questioned the applicant as to whether the hole had existed during the CILRT or had
c
. -
been created afterward. The applicant stated that they had a foreman on the job who knew the hole had been there as long as he had been working at Clinton, specifically a period of two years. Upon hearing this, the inspector, in conjunction with Region III management, identified the following concerns:
(1) What effect did the hole have on containment integrity?
(2) Did the presence of the hole invalidate the CILRT results?
(3) Why the required CILRT pretest inspection did not identify the hole?
(4) Why had the hole remained undiscovered for a period in excess of two years?
Further investigation revealed the leakage through the hole appeared to be attenuated by the concrete portion of the containment structure, which had been poured using the containment liner as the inner form. As a result, the leakage through this hole, as apparently(measured leak rate see Paragraph by 4). the earlier CILRT, A preliminary wasby evaluation less the than the allowab inspector as to what effect the hole would have on containment integrity revealed that if leakage through the hole was not atienuated, the hole would cause the containment to leak app.oximately an order of magnitude greater than the maximum allow 0bl Several questions must be answered to determine if the hole, taken by itself, could have invalidated the preoperationt' CILRT results. They are:
(1) The liner, not concrete structure poured around the liner, is the containment leaktight barrier. Did the CILRT test pressure equalize (due to air leakage through the hole) across the liner, thus leak testing the concrete structure, not the liner?
(2) The applicant performed a 9.25 hour2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> short duration CILRT instead of the normal 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> CILRT. Would a longer CILRT (i.e. 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />) have identified any additional leakage through the hole?
To determine if pressure equalized across the liner, the inspector questioned personnel in IP startup and reviewed test resul ts . The inspector found that prior to the SIT, test personnel identified areas on the liner that when tapped, had a hollow sound, indicating that there were spaces between the liner and surrounding concrete structure. During the pressurization portion of the SIT, people entered the containment and tapped on the areas which had previously emitted a hollow sound. These areas no longer sounded hollow, indicating the pressure was pushing the steel against the concrete structure as designed. This means that pressure was felt on only
. .
one side of the liner indicating that at these locations the pressure had not equalized across the liner due to the hol Due to the short duration CILRT, questions about the acceptability of the CILRT as it related to the hole being a potentially unrealized leak path were generated. The entire CILRT duration was approximately 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />; whereas, the duration of a normal CILRT would be approximately 33 hours3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> (this would include stabilization and verification portions). This question does not appear to be a plausible one because the time at pressure for the SIT and CILRT was in excess of 33 hour3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> Further proof could have been obtained if the applicant had chosen to perform a diagnostic leak test on the hole. The applicant chose not to, citing the potential for liner degradation should the hole be pressurized to leak rate test pressur The fact that the applicant did not identify the hole during the required pre-CILRT liner inspection indicated that this inspection was not of sufficient depth. Interviews with
_
applicant personnel indicated that approximately 74 man-hours of inspection time was put into inspection of the liner. The position taken at the time of this report by the applicant was that the time spent on the inspection was far in excess of what is normally spent on these inspections by other utilities, and the hole was not readily visible and could have easily been missed. The inspector noted the applicant's position, but disagreed with their position that the hole was difficult to see. During the portion of the inspector's inspection performed after the hole was discovered, the inspector noted the hole was readily visible with binoculars (an inspection tool the applicant had available) from two separate elevation Failure by the applicant to identify the hole in the liner during the required pre-CILRT general inssection is an example of a violation (461/85060-04.a(DRS)) of t7e 10 CFR Part 50, Appendix B, Criterion II requirement for control of activities affecting qualit The hole remaining undiscovered for a period in excess of two years was of great concern to the inspector because it represented an undocumented / uncontrolled work activity that was never inspected. The fact that it was discovered by a planned Quality Assurance inspection of a nearby modification is fortuitous, in that if the modification had been in a different location, the plant may have began operation without ever discovering the hole. Failure by the applicant to identify the hole in the liner in a timely fashion is indicative of a breakdown in the applicant's Quality Assurance program and is a second example of a violation (461/85060-04.b(DRS)) of the 10 CFR 50, Appendix B, Criterion II requirement for control of l
activities affecting quality.

. .
To date, the applicant has proceeded with the processing of the deviation report on the hole and the subsequent repair work required by the disposition of the deviation repor At the conclusion of the inspection, the applicant had prepared the area for weldin Evaluation of Post CILRT Control of Work To make a determination as to the adequacy of the applicant's control of work on the containment liner, the inspector performed a containment liner walkdown to find out how the work on the liner had been controlled since the CILR The inspector, along with personnel provided by the applicant, walked down approximately 25% (11,000 ftz) of the liner between elevations 737 and 856 and identified five areas where there were indentations or gouges in the liner which exceeded the maximum allowable depth specified in inspection documents. Additionally the inspector identified approximately 30 areas where work appeared to have recently (since the ILRT) been performed on the liner and requested the applicant provide documentation showing how the work had been controlled. Of these 30 requests for information, the applicant was able to provide documentation for all but six areas showing that either IP's Nuclear Station Engineering Department had concurred with the work prior to it being performed or that the work had been performed prior to the CILRT. IP had no firm position why the s_ix areas had no paperwork, just conjecture that perhaps painters had cleaned the areas, removing the paint to base metal. To determine if the painters had done this, the inspector questioned a painter foreman who stated that when painters were repairing paint damage, they would cover the entire area, not just one distinct poin The undocumented areas were generally in out-of-the-way places and were only one of several in the area. These areas also had places with paint damage or deterioration closeby. In addition, the inspector noted that when painters prepared an area for painting, the area was generally square or rectangular. The areas in question were not typical of the way the painters worked. These observations gave credence to the inspector's position that these areas had not been worked on by.the painters. These observations indicated that the applicant did not have sufficient controls to ensure that work inside containment did not adversely affect the containment line Another area of concern to the inspector centered around the removal of attachments. Specifically, while interviewing the applicant's personnel, the inspector discovered that at least one temporary attachment had been removed by the craft using a cutting torc This was contrary to the applicant's guidance on how to remove temporary attachments (grinding only) and was of particular concern to the inspector, because the hole in the containment resulted from the use of a cutting torc __

During the inspector's walkdown, the inspector noted the large workforce in the containment (200-300 people) approximately 20 of
.,. them welding and another 30-40 grinding inside the containment,
+
although all of them were not working on the line The inspector also noted there was no access control to the containment, so the applicant could not control the number of people or the type of work they were performing inside the containmen c. Review of Post CILRT Work in Containment The inspector requested that the applicant identify how many modifications had been performed on the containment liner since the performance of the CILRT so the inspector could evaluate the level of effort on the line The following is a summary of what the applicant provided:
- 397 work documents were generated for liner work / inspection
- 45 attachments were removed from the liner
- 32 attachments were added to the liner
- Five travelers were issued for safety-related work on the liner As denoted above, a large number of hangers were removed and installed since the performance of the CILRT,which is indicative of a high level of construction effort. When the inspector requested the above information prior to the performance of the CILRT, the applicant supplied a status of Structural Travelers for the containment building which did not identify the above informatio In addition, the inspector requested the applicant supply a list of the work yet to be performed inside the containment structure. The punchlist they supplied identified approximately 850 punchlist items for work items remaining to be performed inside the containmen This indicated that there would continue to be a high level of construction effort inside the containment structur d. Summary When taken by themselves, the information in the preceding three paragraphs may appear to be unrelated. Taken together, it is clear that since the performance of the CILRT, there had been a high level of effort expended on the containment liner. Also, there would continue to be a high level of effort in the containment structure for months to come. To date, the applicant appears to have had some control of the work performed on the containment liner. However, the control has not been sufficient to ensure that containment integrity is being maintained at a level to support the CILRT results as being representative of the containment's leakag . _ . . - - . _ _ _

The~ inspector reviewed the regulatory requirements contained in 10 CFR 50, Appendix J to determine if the activities performed since the CILRT did, in fact, impact on the acceptability of the CILRT as the "Preoperational CILRT." The applicable regulatory requirements out of Appendix J are as follows:
