Subject:

Request for Schedular Exemption From Type A Integrated Leak Rate Test (ILRT)

Requirements (TAC No. M91530)

Gentlemen:

Nonh Atlantic Energy Service Corporation (Nonh Atlantic) hereby requests a one time schedular exemption from the testing nequirements of 10 CFR 50, Appendix J, Section Ill.D.l(a). This request for schedular exemption is submitted pursuant to the provisions of 10 CFR 50.12(a)(1).

On January 25,1995, North Atlantic submitted License Amendment Request 94-08 [ Reference (b)] which requested a change to Seabrook Station Technical Specification 4.6.1.2.a to replace the prescriptive "d0 i 10 month" Type A test requirement with the requirement " intervals as specified in 10 CFR 50, Appendix J". This request is for a one-time schedular exemption from the requirements of 10 CFR 50 Appendix J that would allow the second Type A test of the first 10-year service period for Seabrook Station to be performed approximately nine months beyond the "approximately equal intervals" requirement of Section Ill.D.l(a). If granted, this exemption request will result in the deferral of the next scheduled Type A test from the founh refueling outage, which is currently scheduled to begin on November 4,1995 to the fifth refueling outage, which is projected to begin in September 1997.

Nonh Atlantic has performed an extensive evaluation and determined that based on the excellent performance of the Appendix J test program and companion programs, this exemption will not result in undue risk to the health and safety of the public and that the exemption is warranted. The enclosure contains an evaluation, exemption request and the 10 CFR 50.12 Special Circumstances in support of this request. In addition to meeting the general standards of 10 CFR 50.12(a)(1) the proposed changes meet the criteria for special circumstances as described in 10 CFR 50.12(a)(2)(ii), (iv), and (v). North Atlantic requests NRC review and approval of this one-time schedular exemption request by June 30,1995.

l-Executive Summary The purpose of this letter is to request a one time schedular exemption from the requirements of 10 CFR 50, Appendix J as it relates to the scheduling of Type A tests. If granted, this exemption will result in a test interval of approximately 59 months between the last Type A test performed during Refueling Outage 2 and the next desired Type A test which wou!d be performed during Refueling Outage 5. This represents an extension of approximately 9 months' from the requirement to perform a set of three tests at approximately equal intervals during each 10 year service period. In this request, North Atlantic provides site specific leak rate test data and conclusions from a PRA analysis to demonstrate that performing 3 Type A tests at "approximately equal intervals" is a requirement that is marginal to safety.

North Atlantic performed a thorough evaluation of the programs and practices at Seabrook Station related to containment leakage. The results of this evaluation demonstrate that based on the consistent superior leakage performance of the containment system, the deferral af the Type A test from the fourth to the fifth refueling outage will not have a significant impact to the her lth and safety of the public. This conclusion is based on several factors which are summarized here:

The combination of the Type B and C local leak rate test programs and the North Atlantic companion programs ensure that the leakage from the containment system is as low as reasonably achievable. The Type A test rarely detects additional containment system leakage beyond what is detected during local leakage rate tests. North Atlantic provides examples of permanent improvements that were completed on the facility to improve the leakage performance of the containment system in section 3.2 of this exemption request.

It has been the consistent experience at Seabrook Station during the three Type A tests conducted from 1986 to date, that any significant leakage paths are detected by the Type B and C testing. The Type A test results have only been confirmatory of the Type B and C test results.

North Atlantic conducts 148 local leak rate tests on 106 containment penetrations. This exemption request will not affect the local leak rate testing frequency or methodology. The superior results of the Seabrook Station local leak rate testing program are put into per:pective by the following:

The minimum pathway leakage rate for all 148 containment penetration tests is less than the strict Technical Spe:ification limit of 0.05 L, for any one penetration, and; The maximum pathway leakage rate for all 148 containment penetration tests is less than the same strict Technical Specification limit for any two penetrations.

A Seabrook Station specific Probabilistic Risk Assessment (PRA) analysb was performed by North Atlantic to detennine the affect on any risk factors associated with extending the Type A test interval by approximately 9 months. The analysis concluded that based on the Seabrook Station specific analyses and similar EPRI analyses, the risk increase from extending the time between Type A tests is imperceptibly small. This is valid for the 59 month duration in addition to longer test intervals.

' Dividing 3 tests into a 120 month period results in 40 month test intervals. Applying a 25%

grace period results in a 50 month maximum test interval.

4 a

The details of each of these points are presented in the body of the exemption request and provide a clear justification for deferring the next Type A test from the fourth refueling outage to the fifth refueling outage.

As presented in the body of the request, this exemption request meets the requirements of 10 CFR 50.12 paragraphs (a)(1), (aX2)(ii), (a)(2)(iv) and (v) for the following reasons:

Based on the excellent performance of the Appendix J Type B and C test program and companion programs, this exemption will not result in undue risk to the health and safety of the public.

The Type A test results as set forth in the exemption request demonstrates that Seabrook Station has a low leakage containment. Three Type A tests have been performed at Seabrook Station without a single test failure, and the highest leakage rate of 0.07092 percent per day is well below the acceptance limit of 0.1125 percent per day and the design of 0.15 percent per day.

An assessment of the risk impact in the exemption request concludes that there is no undue risk to the public health and safety as a result of the proposed schedular extension of the Type A test.

Resources now being expended on meeting the requirements of Appendix J for the fourth refueling outage Integrated Leak Rate Test (ILRT) could be better utilized to prepare for and execute other functions with a higher impact on safety during the remainder of Cycle 4 and during the refueling outage.

The proposed exemption only extends the ILRT from the fourth refueling outage to the fifth refueling outage. North Atlantic is requesting a one time exemption from Section Ill.D.l(a) of Appendix J that refers to performing ILRTs "... at approximately equal intervals" during each 10 year service period.

In view of the infonnation contained in this exemption request, we believe that our request for a one-time schedular exemption from the Type A test isjustified under 10 CFR 50.12.

The estimated savings from not performing a Type A test during the upcoming outage in November 1995 exceeds $2,180,000. This includes equipment and contractor costs, in-house person-hours and the replacement power costs associated with lost generation.

l

i 1.0. PURPOSE AND BACKGROUND 1.1 Purpose i

Nonh Atlantic i equesting a one-time schedular exemption from the requirement of Section III.D.1 (a) of Appendix J to 10 CFR 50, if granted, this exemption would permit North Atlantic to perform the second Type A test of the first 10 year service period during the fifth refueling outage, OROS, instead of the fourth refueling outage, ORO4.

To meet Appendix J requirements, the next Type A test would be performed during the fourth refueling outage which is scheduled to begin in November 1995. This would occur approximately 37 months afler the October 1992 Type A test. Moving the Type A test to the fifth refueling outage, which is scheduled for September 1997, would result in an interval of approximr.tely 59 months between the two Type A tests. The actual outage stan dates depend on cycle performance.

In addition, to this schedular exemption request, North Atlantic has proposed a change to Technical Specification Surveillance Requirement 4.6.1.2.a to revise the specific requirements for the frequency of Type A tests from "40 t 10 months with "at intervals specified in 10 CFR 50, Appendix J". This license amendment request was submitted on January 25,1995, via NYN-95005.

I.2 Baekcround North Atlantic has implemented a containment leakage test program as required by Appendix J,10 CFR 50 and the Seabrook Station Technical Specifications. This program is described in North Atlantic's "Seabrook Leakage Test Reference Manual"(SLTR).

The purpose of the Type A test, as discussed in Appendix J,10 CFR 50, is to assure:

1.

leakage through the primary reactor containment and systems and components penetrating the primary reactor containment shall not exceed allowable leakage rate values as specified in the Technical Specifications or Updated Final Safety Analysis Report, and 2.

periodic surveillance of reactor containment penetrations and isolation valves is performed so that proper maintenance and repairs are made during the service life of the containment, and systems and components penetrating primary containment.

As discussed in Nonh Atlantic's SLTR, the Type A test is considered as a double check on the existing work control and surveillance programs. In addition to the Type A, B and C testing, other companion programs are implemented to ensure that only authorized activities are perfonned and that proper maintenance and repairs are promptly made during the service life. Some of these activities include other surveillance tests, general walkdowns of equipment during plant operation, design control, and work control measures. The North Atlantic Companion Programs are descrhed in Section 5.0 of this exemption request.

North Atlantic performed the preoperational Type A test in March 1986. Due to delays in obtaining the Operating License, commercial operation did not commence until August,1990. During this delay, the containment integrity program was maintained. Because systems were in service and the plant was maintained in a state of readiness, periodic Type B and Type C tests were performed. In November, 1989, approximately 45 months after the preoperational Type A tem another Type A test was performed.

Pagei

In October 1992, approximately 35 months after the 1989 Type A test, a third Type A test was performed during the second refueling outage (ORO2).

The results of the three ILRTs performed to date have been consistent and are well within the limits prescribed in 10 CFR 50, Appendix J.

In this exemption request, North Atlantic demonstrates that d ferring the ILRT from the fourth refueling outage to the fifth refueling outage does not result in a s gnificant increase in risk to the public.

This exemption request involved approximately 250 hours0.00289 days 0.0694 hours 4.133598e-4 weeks 9.5125e-5 months preparation time. It was prepared by NAESCO's Engineering Depanment, Component Performance personnel that have responsibility for Nonh Atlantic's 10 CFR 50, Appendix J Program.

1.3 Hasis for Exemption North Atlantic has evaluated the proposed change against the criteria for specific exemptions as described in 10 CFR 50.12.

The NRC has historically recognized that there are circumstances where on balance it would not be equitable or in the public interest to require literal adherence to regulation. This has been particularly true in situations where expending plant resources to satisfy the literal adherence of a requirement would not result in a commensurate improvement in overan safety or a commensurate reduction in risk to the public.

This assessment, as presented in this exemption request, clearly demonstrates that literal adherence to the regulation would not serve the underlying purpose of the rule. This assessment will also show that North Atlantic has consistently maintained a very high containn'ent integrity standard since the preoperational ILRT was completed in 1986. Since that time, North Atlantic has consistently upgraded and made changes to its programs. These changes include imp ovements in test procedures, addressing Code jurisdictional boundary overlap issues, and impicmenting lesign changes to improve leakage rate performance. These t.ctivities, as part of an on-going program, clearly demonstrate that North Atlantic has developed a technically sound and proven method for achieving and exceeding the underlying purpose for accomplishing the regulatory purpose of the rule.

As stated in North Atlantic's SLTR, the Type A test is a proof test that measures the effectiveness of the Station's work control and su <eillance test control programs. Nonh Atlantic has instituted a program that includes other companion programs to ensure that only authorized activities are performed, and that proper maintenance and repairs are promptly made during the service life. Therefore, the Type A test is simply the confirmation test of the Type B & C testing and the other companion programs.

Recent industry analysis ofILRT reports has concluded that the Type A tests rarely detect leakage paths not readily identified by the Type B or Type C Programs.

This analysis validates the conclusion that local leakage rate testing (LLRT) can detect essentially all potential degradations of containment integrity.

The database used was a compilation of LERs, FSAR revisions, ILRT repons, exemption requests, technical specification changes, etc. from June 1987 through April 1993. Of specific interest were 166 ILRT repons covering 97 individual plants at 68 sites. In all of the cases studied, LLRTs did not and could not detect excessive leakage in three of the cases identified as a failure.

Page 2

l These results indicate that:

Type A testing detected approximately 3% of all failures to meet the current leak-tightness requirements.

]

Type B and Type C testing can detect a very large percentage of containment leakages.

The percentage of containment Isakages detected only by Type A testing is very small.

+

The ILRT failures that were not detected by Type B and Type C testing had very small leakages rates, only marginally above the current leak-tightness requirements.

North Atlantic currently has a comprehensive leakage test program in place. The program, which is described in the following sections, not only meets, but exceeds the underlying purpose for accomplishing the regulatory purpose of the rule. Performing an ILRT during the founh refueling outage places a j

regulatory burden on Nonh Atlantic, because an ILRT:

1) has been recognized in the industry as "a requirement that is marginal to safety" (ILRT only detects 3% of the failures) 2)

is not effective in detecting degradation of the containment system (LLRTs plus other measures detect 97% of the failures) 3)

does not acknowledge the effectiveness of other programs that are more efficient in detecting degradation (closed system testing, work control program, design control program, leakage reduction program, health physics & operations walkdowns that are currently in place at North l

Atlantic)

~

4) requires scheduling that requires:

i) 3-4 days of critical path time with additional scheduling pressures to re-sequence cenain activities that normally would either be done in parallel, or at a later time in the stanup, ii) additional outage time for preparation and recovery, and iii) significant plant resources to perform, approximately 3000 person hours.

2.0. NORTH ATLANTICILRT RESULTS AND ANALYSIS-1989 AND 1992 ILRTs 2.1 1LRT Results The following discussion penains to the 1992 and 1989 ILRT result summaries that are included in this section. This data is extracted from North Atlantic's 1989 and 1992 ILRT reports that were prepared and submitted in accordance with Appendix J,10 CFR 50. Both the 1989 and 1992 ILRTs test results J

presented in this section use the mass point method. The 1992 ILRT was a 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months reduced duration test j

that used the Bechtel Topical Report, BN-TOP-1, Rev.1.

The fol'owing total reponed As-Found ILRT leakage rates are based on USNRC Information Notice 85-71. This technique, which is referred to here as the repair improvement method, calculates the As-Found ILRT (test result if ILRT was done at the beginning of the outage) results. This is done by using the As-Left ILRT (done at the end of the refueling outage after repairs to the LLRT boundaries have already been performed) results and adding the minimum pathway repair improvement for all of LLRT boundaries.

The minimum pathway leakage rate is the minimum leakage rate that can be attributed to a penetration leakage path (e.g., the smallest leakage of two valves in series). The maximum pathway leakage rate is the maximum leakage rate that can be attributed to a penetration leakage path (e.g., the larger, not the total leakage of two valses in series). This generally assumes a single active failure of the better of two leakage barriers.

2.2 North Atlantie ILRT Analysis

[

t From a performance-based approach, the following ILRT Analysis - 1989 and 1992 ILRTs discussion demonstrates that North Atlantic:

i has completed two successful (As-Found) ILRTs (e.g., the 1989 and 1992 Type A tests) in addition to the successful 1986 preoperational ILRT, has since 1986, consistently made repairs and modifications to the containment isolation system 2

The results of the three ILRTs performed to date have been consistent and are well within the limbs i

prescribed in 10 CFR 50 Appendix J.

j 3.0 NORTH ATLANTIC LLRT RESULTS AND ANALYSIS 3.1 North Atlantie's LLRT Program Results Since 1986 This section contains a summary listing of North Atlantic's Local Leakage Rate 'I est (LLR1) Prog am results since the preoperational Type A test which was performed in 1986. Recen. industry analysis of ILRT Reports has concluded that the Type A tests rarely detect leakage paths not res : lily identified by t he Type B or Type C Program. Given a through understanding of the purpose t f each test and he boundaries that they challenge, this is not an unexpected result.

' The test result of the preoperational ILRT performed in 1986 was 0.058 percent / day.

Page 5

A review of the LLRT Program results is very important in the decision to extend the ILRT from the fourth refueling outage to the fifth refueling outage.

There are two parts to this section. Subsection 3.1.1, presents the Maximum and Minimum pathway totals for 4 different time periods. Subsection 3.1.2, presents the individual penetration leakage rate results which include the as-found data, the as-left data, and any applicable remarks such as repair summaries, changes to the test method, design changes, etc. The Maximum and Minimum Pathway Summaries and the Individual Penetrations are contained in Attachment 1.

3.1.1 LLRT Maximum and Minimum Pathway Summaries The Maximum and Minimum Pathway results are presented below to allow for comparison and to show the improvement that has been achieved. The total allowable leakage for Type B and Type C tests and for combined bypass leakage is 0.60 La'.

De La equivalent is also shown with each total. North Atlantic has an individual penetration limit of 0.05 La or 37 standard cubic feet per hour (SCFil). The two Containment On-Line Purge penetrations have a limit of 0.01 La or 7.4 SCFIL CONCLUSION:

1.

The Maximum and Minimum pathway leakage total have been steadily reduced since the date of the Preoperational ILRT in 1986.

2.

There are currently 81 Type C tests and 67 Type B tests in the North Atlantic LLRT Program.

The 1994 minimum pathway analysis for 148 LLRTs is less than the strict Technical Specification Limit for ONE penetration.

Page 6 contains LLRT As-Found and As-Left LLRT results for each penetration that is in the 1

LLRT Program. Each sheet shows one boundary, including the inside and outside reactor containment isolation valve, designated as IRC or ORC, respectively.

Also shown is the component tested, the Maximum Pathway calculation bases, the minimum pathway j

bases, the applicable Technical Specification Limit for the penetration, and the maintenance improvement summary when a repair to a component was performed 3.2 LLRT Analysis i

The LLRT component test program is described in Seabrook Station's Leakage Test Reference (SLTR)

Manual. This manual contains not only the components included in the Type B and Type C leakage program, but also the components not included and the reason for their exclusion.

Type B Program i

North Atlantic's Type B Program tests electrical penetrations, fuel transfer tube (bellows and flange),

equipment hatch (flange O-ring, and airlock), personnel airlock, two rnechanical spare penetrations with Ranged closures (0-rings), hydrogen analyzer trains, and two ventilation penetrations with flanged closures (0-rings).

These tests are conservative because the Type B LLRTs test between the two barriers (e.g. between two 0-rings, seals, airlock doors, or bellows), whereas the leakage path during a loss of coolant accident (LOCA) would cross through both barriers. The equipment hatch, which is approximately 28' in diameter, is a spherical dish that extends into containment. This means that internal containment pressure will help seat the equipment hatch versus unseating.

As a point of interest, one of the few industry failures that an ILRT did detect was a BWR containment head flanged connection. The LLRT did not detect the problem since the pressure in the test channel volume is not equivalent to the pressure exerted by the ILRT on the interior surface of the entire spherical surface. The BWR containment head in the cited failure is a large spherical dish that extends away from containment. His, as noted above, is different than the Seabrook Station equipment hatch which extends into the containment.

Type C Program North Atlantic's Type C Program tests 39 penetrations. All except three of the valves associated with these penetrations are leakage tested in the same direction as that when the valve would be required to perform its safety function (e.g., the forward direction). The three valves that are reverse tested (e.g.,

tested in the opposite direction) provide either more conservative or equivalent leakage test results. One of the valves is a relief valve that would have accident containment pressure seat the valve. Because the outlet connection is a welded end, the LLRT is performed by putting test pressure under the valve seat.

This provides conservative test results. The remaining two valves are POSI-SEAL butterfly valves with a T-Seal ring and provide equivalent results. The vendor states that these valves are capable of bi-directional sealing and this conclusion is supported by the leakage test results.

The LLRTs essentially duplicate the ILRT test challenge. The LLRT program does not benefit from performing an ILRT.

Page 7

i These LLRT summaries were extracted from the Inservice Test (IST) Program liistory Logbooks. The IST logbooks will be maintained to show the history, however the test result review and trending features i

that are performed as part of the 10 CFR 50, Appendix J Program will become part of the Maintenance Rule Program.

Several improvements to the Containment Isolation Systern have been made to resolve problems i

encountered with containment isolation valves. Some of these improvements are:

i a.

The largest piping penetrations, HVAC1 and liVAC2, were modified to use blank flanges with testable O-Rings versus 36 inch butterfly valves during Modes 1-4.

l h.

Reactor Make-up Water valve, RMW-V30 was replaced as a conservative measure as a l

result of a minor problem identified in the 1989 ILRT.

I c.

Several Primary Component Cooling Water (PCCW) block valve refurbishments occurred which reduced the leakage assigned to the associated containment isolation valve (s).

d.

The replacement of containment air handling valve Call-V12 with a difTerent style of valve (e.g., soft seat) to improve leakage performance, j

e.

Rework of combustible gas control valve CGC-V4 to restore dimensions of the internals in order to improve leakage performance.

In some cases, the test methods were changed to permit individual testing of components. In particular, several penetrations were modified in 1992 including the IIVAC penetrations. Also several poetrations were modified to permit the penetration relief valve to be individually tested in place. Other improvements include the addition of Combustible Gas Control (CGC) penetrations to the LLRT Program j

to track and maintain integrity of the hydrogen analyzer closed systems outside of containment, and several changes in test method to allow individual valve leakage assessment, or to test in the accident direction versus testing in the reverse direction.

4.0 SEABROOK STATION SPECIFIC RISK ANALYSIS A Seabrook Station specific Probabilistic Risk Assessment (PRA) analysis was performed by North Atlantic to determine the affect on any risk factors associated with extending the Type A test interval by approximately 9 months.

i The first affect of extending the Type A test has been addressed in research and analysis directed by the i

Electric Power Research Institute (EPRI'). Seabrook Station matches up well with Zion, based on similarities in containment design (large, dry high-strength structure). In addition, the EPRI representative l

plant also included a PWR with a large, dry containment. Thus, these two cases support North Atlantic's case. The Seabrook Station specific analysis that was also performed, used the same methodology, and is summarized below.

From the Seabrook Station specific analysis, the risk from extending the duration of the Type A test may affect two important risk indexes, early health effects (also termed, large early release frequency - LERF) and latent health effects (cancers or person-rem exposure).

' EPRI TR-104285, " Risk Impact Assessment of Revised Leak Rate Testing Intervals," Final Report, August 1994.

Page 8

The results from the current Seabrook Station PRA update (SSPSS-1994) show a very low frequency for large early release (LERF = 1.4E-8/yr). One of the contributors to this is large pre-existing leaks, the type that would likely be found by the Type A test, or as North Atlantic maintains, that the companion programs would likely also find. Even if this probability were to increase by an order of magnitude due to extended duration of testing (a bounding assumption), the LERF would still be very small, more than two orders of magnitude below the core damage frequency, (CDF) of 7.2E-5/yr.

It is the " intact containment" case that EPRI modeled for the impact of containment leakage. Using risk results from the "Seabrook Station Risk Management and Emergency Planning Study"(RMEPS)', the risk (person-rem exposure) from an "S5" release (Seabrook Station intact containment case, with Technical Specification allowved leakage given core damage event) is 1.lE-4/yrx273 person-rem = 3.02E-2, or 0.041% of the totall person-rem risk (-78). (While the estimated total CDF has decreased from the time of the RMEPS study, the relative contributions are expected to be reasonably constant. Also, note that Table D-5 repotts cancer fatalities; the conversion to person-rem is SE-4 cancers per person-rem, from RMEPS, Table 5-1.)

The following analysis parallels Section 5.1 of the referenced EPRI analysis for the PWR Risk Impact.

The time between tests is 37 months for the base case and 59 months for the extension. Note: These time periods are expecteddurations. Assuming a constant failure rate for leakage, the average time that a leak is undetected is 18.5 months and 29.5 months (one-half the duration between tests), or an increase in time of about 1.6. Thus, the increase in the probability ofleakage is 1.6x3% = 4.8% (That is, assuming that containment leaks occur at random, but at a constant rate, the extension of the time between Type A testing by a factor X increases the probability of leaks that a Type A test could detect by Xx3%)

Consistent with the EPRI analysis, the assumption that the leakage rate due to the extended testing is 2 x La, or twice the TS allowed leakage. The consequences, assuming linearity with leakage rate, increase by a factor of two (273 person-remx2 = 546). Thus, the risk due to the extension in testing duration is:

1.lE-4/yr x 546 person-rem /yr x 4.8% increase in leakage = 1.lE-4x546x1.048 =

6.3E-2 person-rem, or (6.3E-2) + 78 = 8.lE-4 = 0.081% of the total risk.

Based on EPRI and Seabrook Station specific analysis, the risk considerations demonstrates that the risk increase from extending the time between Type A tests is imperceptibly small. This statement is valid for the ~59 month duration that would result from performing the ILRT during the fifth refueling outage.

It is also valid for an extension up to 10 years between Type A tests.

i North Atlantic performs the ILRT at the end of the outage, in Mode 5, and the test is on critical path.

1 To minimize the risk of a substantial, unexpected delay during the performance of the Type A test, the North Atlantic test group has developed and maintained cenain test functions as well as coordinate related activities. These companion programs help ensure that only authorized activities are performed, and that proper maintenance and repairs are promptly made during the service life.

As discussed previously, LLRTs detected a very large percentage of the failures (e.g., approximately 97%)

while ILRTs detected less than 3% of the failures. Even though ILRTs provide marginal benefits to improving safety, their performance presents a real challenge to each plant. Besides dealing with the

{

conduct of the LLRTs and preparing for the ILRT, the plant's test group is also concemed with other

~

issues that can cause substantial delays in the performance of the ILRT. Certain activities have to be re-l sequenced to be complete prior to the ILRT when normally they would be done later in the plant stanup.

By addressing these issues, Nonh Atlantic not only achieves the near leak tight containment isolation system, but also minimizes the risk for delays during scheduled ILRTs.

The purpose of the ILRT or Type A test is to measure the overall integrated leakage rate from the reactor l

containment system. The overall integrated leakage rate is the total leakage through all potential leakage paths (e.g., liner welds, valves, mechanical joints, fittings, electrical penetrations, closed systems, and other penetrations). Since the ILRT is the only program that measures all of the leakage, it is considered as a double check of all the LLRT test program and the other companion programs. A brief description of each of the companion programs and how North Atlantic uses the programs to maintain the containment isolation system and are discussed below:

5.1 Eneincered Safety Features Engineered Safety Features systems serve to limit the potential radiation exposure to the public and to plant personnel following an accidental release of radioactive fission products from the Reactor Coolant i

System, particularly as the result of a loss-of-coolant-accident (LOCA). The safety features addressed in i include:

Containment Structure I

Containment Enclosure Building Containment Enclosure Emergency Air Cleaning System (CEEACS)

Containment Enclosure Bypass Leakage LOCA Radiological Consequences 5.2 Closed System Inteerity Program North Atlantic addressed "the closed system boundary" issue as a potential for delays in the performance I

ofILRTs. This issue deals with discovering a communication path between the containment atmosphere and outside environment during the ILRT. This discovery can take several hours to predict the leakage magnitude, and several hours to detect the potential boundary. In some cases the boundary is not isolable and would require containment depressurization to find the problem and to correct the condition.

The two closed systems identified by Nonh Atlantic were the PWR secondary side boundary and the hydrogen analyzer loops.

i l

l Page 10 N-r-

Secondary Side Because of the complexity of the steam generator secondary side closed system boundary, a separate periodic surveillance test was developed to detect potential communication paths, and to initiate corrective maintenance well before the performance of the ILRT. This test pressurizes the secondary side boundary with air, and then performs a detailed exa.nination of all the accessible mechanical joints (e.g., bolted joints, threaded connections, flanges, packing, etc.)

This surveillance duplicates the walkdowns some plants perform as a part of the normal startu,; (e.g.,

steam leakage checks as system temperature is increased), however damage to equipment can occur if this is the only check. In addition, some leakage paths are not as easily detected as they are with a pneumatic test. The important issue is when these other walkdowns are performed. They are usually performed after the ILRT.

To avoid ILRT delap of up to 4-5 days, or delays in plaat startup, and to avoid major damage to equipment (e.g., steam cutting) North Atlantic performs the secondary-side I. & age test e ery refueling outage.

Ilydrogen Analyzers Per the Seabrook Station UFSAR, the manual containment isolation valves on the Combustible Gas Control (CGC) hydrogen analyzer lines are not required to be Type C tested. These lines form a closed system outside of containment. The integrity of the closed system was to be periodically verified by opening the manual isolation valves and exposing the closed system outside containment to the ILRT test pressure.

Since testing the manual containment isolation valves required containment entry, and since the potential existed for periodic maintenance of the analyzer unit (e.g., sometimes involving system breech during plant Modes 1-4). both the manual ccatainment isolation valves and the entire hydrogen analyzer loops were added to the LLRT Program.

This modification now permits maintenance during Modes 1-4, and the option of isolating the hydrogen analyzers during the Type A test and adding their leakage contribution to the measured Type A test results. This testing practice readily identifies any potential leakage paths and prompt corrective action.

5.3 Leakace Reduction Programs There are two refueling outage interval programs involved in leakage reduction. They are the TMI lil.D.I.1, Integrity of Systems Outside Containment Likely to Contain Radioactive Material Program and the Generic Letter 88-05 Program.

5.3.1 TMI Leakace Reduction Procram The purpose of this program is to comply with North Atlantic Technical Specification 6.7.4 a, Primary Containment Sources Outside Containment, by periodically inspecting and measuring leakage in portions i

of safe shutdown and post-accident monitoring systems that are located outside containment. The systems included in this program are Residual lleat Removal (RH) i Containment Building Spray (CBS)

5.4 Desien Contml Procram As discussed in Attachment 4 Engineered Safety Features, under the containment structure section, North Atlantic's containment structure was designed using the technical provisions of ASME Section 111, Division 2. The applicable Code Edition / Addenda as discussed in 'UFSAR 3.8.1.2 is the 1975 ASME Boiler and Pressure Vessel Code, Section 111, Division 2, Code for Concrete Reactor Vessels and Containments, Edition (1976 Winter Addenda used for liner allowable stresses).

North Atlantic is monitoring the USNRC's proposed rule on Codes and Standards for Nuclear Power Plants: Subsections JWE and IWL and the requirements as they relate to modifications to the containment j

system. Any new requirements as they relate to the containment structure will be addressed in North Atlantic programs.

There are no currently approved plans for containment liner or containment penetration modifications that would require an ILRT.

Page 12 1

North Atlantic adheres to the requirements of 10 CFR 50, Appendix J, Paragraph IV.A regarding "any major modification, replacement of a component which is part of the primary reactor containmetit boundary.. shall be followed by a Type A, Type B or Type C test, as applicable for the area affected by the modification".

COMMITMENT 1 To help emphasi:e this requirement, North Atlantic will reference the portion of10 CFR 50, Appendix J in the Design Control Afanual " Preparing, Processing. and Closeout of Design Coordination Reports" (DCRs), Figure 5.1, Design input Guide.

5.5 Work Control Maintenance performed on the components affecting the containment boundary would require compliance with North Atlantic's Maintenance Manual. In particular, the " Post-Maintenance Testing" and "ASME Section XI Repair and Replacement Program" would apply, i

The " Post-Maintenance Testing" procedure references the Station Leakage Test Reference Manual (SLTR) and contains a listing of Type B and Type C components that are included in the 10 CFR 50, Appendix J test program. The SLTR, Special Testing Requirements section also discusses the requirements of 10 CFR 50, Appendix J. Paragraph IV.A regarding "any major modification, replacement of a component which is part of the primary reactor containment boundary... shall be followed by a Type A, Type B or Type C test, as applicable for the area affected by the modification".

The "ASME Section XI Repair and Replacement Program" requires a Section XI traveler be prepared to augment the work document. Work on the Containment Liner or on a piping system connected to the containment would require a Section XI traveler, North Atlantic adherrs to the requirements of 10 CFR 50, Appendix J, Paragraph IV.A regarding "any major modification, replacement of a component which is part of the primary reactor containment boundary... shall be followed by a Type A, Type B or Type C test, as applicable for the area affected by the modification" COMMITMENT 2 To help emphasi:e this requirement, North Atlantic will reference this section of10 CFR 50, Appendix J in the Post Afaintenance Test procedure and the ASAfE Repair and Replacement Program (e.g., to highlight liner work, Type B work or a reference to the SLTR).

5.6 Containment and Containment Enclosure Buildine Surface Examination in accordance with Seabrook Station's Technical Specifications,4.6.1.6, Containment Systems, Primary Containment, Containment Vessel Structural Integrity and 4.6.5.3, Containment Systems, Containment Enclosure Building Structural Integrity, visual inspections of the exposed accessible interior and exterior surfaces of the containment and containment enclosure building are performed during shutdown for each j

Type A test.

The purpose of these inspections is to detennine if there are any apparent changes in the appearance of the surfaces or other abnormal degradation. The containment structure is passise. Under normal conditions there is no significant environmental or operational stress which could contribute to its Page 13

degradation. Passive failures resulting in significant containment structural leakage are therefore extremely unlikely to develop between Type A tests. No such failures have ever occurred at Seabrook Station.

North Atlantic will continue to perform these inspections every other outage and when a Type A test is scheduled.

COMMITMENT 3 North Atlantic will perform a containment and containment enclosure surface inspection per the procedure: " Containment and Containment Enclosure Surface Inspection" during thefourth refueling outage, even of the one time schedular exemption to perform the Type A test during thefifth refueling outage is approved.

6.0 10 CFR 50.12 ANALYSIS 50.12(a)(1)

North Atlantic believes that the proposed changes are not in violation of any applicable law, will not present an undue risk to the public health and safety and will be consistent with the common defense and security. In section 4.0 of this exemption request, North Atlantic demonstrates a minimal increase in risk of less than 1/10th of one percent as measured in person-rem as a result of extending the Type A test interval.

In addition to meeting the general standards of 10 CFR 50.12(a)(1) the proposed changes meet the criteria for special circumstances as described in 10 CFR 50.12(a)(2)(ii), (iv), and (v).

50.12(a)(2)(ii)

The interval requirements specined in Appendix J are not necessary to achieve the underlying purpose of the rule. The stated purpose in Appendix J of 10 CFR 50 for containment leakage rate testing is:

i 1) to assure that leakage through the primary reactor containment and systems and components penetrating primary containment will not exceed allowable leakage rate values a., specified in the technical specifications or associated bases 2) to assure that periodic surveillance of reactor containment penetrations and isolation valves is performed so that proper maintenance and repairs are made during the service life of the containment and systems and components penetrating primary containment North Atlantic's assessment, as presented in this exemption request, demonstrates that North Atlantic has developed a technically sound and proven method for achieving and exceeding the underlying purpose for accomplishing the regulatory purpose of the rule. As presented in section 2.1 of this exemption request, the As-Found Type A test results were well within the regulatory limit specified in 10 CFR 50, Appendix J. In fact, the results of the 1989 and 1992 Type A tests were very consistent at 0.0601 percent / day and 0.07092 percent / day, respectively. In addition, the 1986 preoperational ILRT yielded results of 0.058 percent / day. The consistent, successful As-Found results of the Type A tests conHrrns that the test does not contribute a benefit to safety over and above that provided by the Type B, Type C and companion test programs.

Page 14

f-The programmatic controls associated with the North Atlantic leakage testing and companion programs as described in this exemption reques provide protection equivalent to the prescriptive requirements of Appendix J while allowing for signiGcant reductions in cost and increases in efficiency. The negligible change in risk provides equivalent assurance that allowable leakage rates will not be exceeded. Valves that are required to close for containment isolation and that are not maintained closed at all times during power operation are stroke tested in accordance with ASME Section XI, subsection IWV. These requirements are at least as restrictive as those of Appendix J. This ensures that proper maintenance and j

repairs can be performed as required by the rule.

$0.12(aM2Miv)

The proposed exemption will, on balance result in a benefit to the public health and safety. The change l

in risk and safety is negligible and essentially neutral as shown earlier. Resources now being expended l

on meeting the requirements of Appendix J for the fourth refueling outage could be better utilized to prepare for other functions with a higher impact on safety during the remainder of Cycle 4 and during the l

refueling outage. For example, the North Atlantic staff responsible for preparing for and executing the i

Type A test would be able to better prepare for and execute activities such as comprehensive check valve

)

inspections and flow tests, Engineered Safety Features (ESP) testing, and Type B and C testing. Directing resources to these types of activities, as opposed to less safety significant Type A testing would result in a benefit to the health and safety of the public. North Atlantic has a demonstrated commitment to safety and will continue to commit resources as necessary to fulfill that commitment.

50.12(aM2Mv)

The proposed exemption only extends the ILRT from the fourth refueling outage to the fiflh refueling outage. North Atlantic is requesting temporary relief from the applicable regulation of Appendix J that refers to performing ILRTs "... at approximately equal ir.tervals" during each 10 year service period.

North Atlantic has completed two successfulILRTs with over 5 years remaining in the 10 year Service period. As presented in this exemption request, North Atlantic has demonstrated good faith efforts to comply with the regulation.

7,0

SUMMARY

AND CONCLUSIONS North Atlantic concludes that the request for an exemption from the requirements of Section Ill.D.1 (a) of Appendix J to 10 CFR 50 are justified pursuant to 10 CFR 50.12(a)(1) and 10 CFR 50.12(a)(2)(ii), (iv),

and (v).

In addition to this schedular exemption request, North Atlantic has proposed a change to Technical Specification Surveillance Requirement 4.6.1.2.a to the requirements for the frequency of Type A tests l

from "40 i 10 months" to "at intervals specified in 10 CFR 50, Appendix J".

This license amendment

{

request was submitted on January 25,1995, via NYN 95005.

]

This assessment, as presented in this exemption request, clearly demonstrates that the strict application of the regulation would not serve the underlying purpose of the rule. This assessment also shows that North Atlantic has consistently maintained a very high containment integrity standard since the preoperational ILRT was completed in 1986. Since that time, North Atlantic has consistently upgraded and made changes to station programs. These changes included making improvements in test procedures, and completed design changes to improve leakage rate performance. These activities, as part of an on-going program, clearly demonstrate that North Atlantic has developed a technically sound and proven method for achieving and exeeding the underlying purpose of the rule.

i 1.

The Maximum and Minimum pathway leakage total have been steadily reduced i

since the date of the Preoperational ILRT in 1986.

2.

Several improvements to the Seabrook Containment Isolation System have been made to address problem valves:

a.

The largest piping penetrations, HVACI and HVAC2, were modified to

[

use blank flanges with testable 0-Rings versus 36 inch butterfly valves during Modes 1-4.

b.

Reactor Make-up Water valve, RMW-V30 was replaced as a conservative measure as a result of a minor problem identified in the 1989 ILRT.

c.

Several Primary Component Cooling Water (PCCW) block valve refurbishments occurred which reduced the leakage assigned to the associated containment isolation valve (s).

d.

The replacement of containment air handling valve CAH-V12 with a different style of valve (e.g., soft seat) to improve leakage performance.

e.

Rework of combustible gas control valve CGC-V4 to restore dimensions of the intemals in order to improve leakage performance.

3.

Addition of CGC penetrations to the LLRT Program to track and maintain integrity of the Hydrogen Analyzer Closed Systems outside of containment.

As-Found and As-Left Penetration Test Results

ATTACHMENT 2 INDIVIDUAL PENETRATION - AS FOUND AND AS LEFT LLRT IIISTORY FROM 1986 TO PRESENT This Attachment demonstrates that Seabrook has been testing, repairing, and maintaining the containment isolation system boundaries since 1986, despite the fact that Commercial Operation did not occur until August,1990.

The following sheets contain LLRT As-Found and As-Left LLRT results for each penetration that is in the LLRT Program. Each sheet shows one boundary (e.g., the inside/outside containment isolation valve designated as IRC or ORC).

Also shown is the component tested, the Maximum Pathway calculation bases, the minimum pathway bases, the applicable Technical Specification Limit for the penetration, and the maintenance improvement summary when a repair to a component was performed.

In some cases, the test method was changed to permit individual tests of components. In particular, several penetrations were modified in 1992 to permit the penetration relief valve to be individually tested in place in other cases, the penetration was modified, e.g. the IIVAC penetrations.

These LLRT summar:e were extracted from the IST Program liistory Logbooks. The IST Logbooks will be maintained to show the history, however the test result review and trending features that are performed as part of the 10 CFR 50, Appendix J Program will become part of the Maintenance Rule Program.

ATTACIIMENT 3 TO NYN-95019 North Atlantic Engineered Safety Features (ESF)

Related to Containment Leakage

?

l

.P e

ATTACHMENT 3 ENGINEERED SAFETY FEATURES Engineered Safety Features serve to limit the potential radiation exposure to the public and to l

plant personnel following an accidental release of radioactive fission products from the Reactor Coolant System, particularly as the result of a loss-of-coolant-accident (LOCA). The safety features discussed in this section deal with containment leakage and include:

I 1.

Containment Structure 2.

Containment Enclosure Building

~

3.

Containment Enclosure Emergency Air Cleaning System (CEEACS) 4.

Containment Enclosure Bypass Leakage 5.

LOCA Radiological Consequences This discussion is a capsule summary ofinformation contained in Seabrook's Updated Final Safety Analysis Report (UFSAR). In particular, UFSAR Sections 1.2,3.8,6.2,6.5, and 15.6.5 were summarized.

Containment Structure i

General The containment, Figures 1.2-5 and 1.2-6 (attached),is a Seismic Category I reinforced concrete dry structure, which is designed to function at atmospheric conditions. It consists of a vertical cylinder topped with a hemispherical dome, supported on a reinforced concrete foundation mat.

The containment structure was designed using the technical provisions of ASME Section Ill, Division 2 code.

A welded steel liner plate, anchored to the inside face of the containment, serves as the leakage

~

membrane.

Technical data Containment Net Free Air Volume As Tested 2,704,024 cubic feet Design Pressure 52 psig i

Calculated Peak Accident Pressure 49.6 psig Containment Design Temperature 296*F l

Maximum Allowable Leakage Rate, La 0.15 %/ day 0.75 La 0.1125 %/ day 4

-m.- -->

--+w- - -.

Dome The dome is a reinforced concrete shell 3' 61/8" thick and 69' 117/8" in radius. Due to the change in concrete thickness, the discontinuity of concrcte (at the springline) is on the outer surface.

The dome liner is 1/2" thick and is flush with the outside face of the cylindrical liner.

Cylinder The cylinder has an inside diameter of 140' and is nominally 4' 6" thick except in thickened areas around large openings (e.g., equipment hatch, or personnel airlock), near the cylinder / dome interface, ano at the cylinder /basemat interface. It has a height of 149' 0" (from the top of the foundation to tue springline).

The liner plate in the cylinder is 3/8" thick in all areas except at penetrations and at the junction of the base mat which is 3/4" thick. The liner is provided with an anchorage system to assure that it can withstand accident loadings while maintaining leak tightness.

Base Mat The reinforced concrete basemat is 153' in diameter and 10' thick. It is designed to carry all loads from the containment and internal structures.

The mat liner plate is 1/4" thick. A 4' thick fill mat covers the mat liner plate.

Steel Comnonents Steel components that resist pressure that are not backed by structural concrete, and that penetrate the lower portion of containment are:

1.

Equipment Hatch (28'in diameter) l 2.

Personnel Airlock (7' 1 1/4" in diameter) 3.

High Energy piping penetrations 4.

Moderate Energy piping penetrations 5.

Electrical penetrations 6.

Fuel Transfer Tube Assembly 7.

Instrumentation penetrations 8.

Ventilation penetrations

i 9

Containment Enclosure Building The Enclosure building is a Seismic Category I reinforced concrete right cylindrical structure l

with a hemispherical dome. It surrounds the containment structure. The inside diameter is 158'.

l The vertical wall varies in thickness from 36" to 15", and the dome is 15" thick. The inside dome is 5' 6" above the top of the containment dome.

7 i

Containment Enclosure Emergency Air Cleaning System The Containment Enclosure Emergency Air Cleaning System (CEEACS) is designed to maintain l

a negative pressure within the containment enclosure following an accident, to remove and retain airborne particulates and radioactive iodine, and to exhaust filtered air to the unit plant vent.

The CEEACS is designed to maintain a negative pressure of greater than or equal to 0.25 inches j

of water following a design bases accident, in the annular region defined by the containment structure and the containment enclosure, as well as in the electrical penetration areas, mechanical penetration area, and in the engineered safeguard equipment cubicles, so that any fission products t

leaking from these systems and from the primary containment will be retained in these areas and eventually processed through these filters.

The exhaust capacity is based on a conservative leak rate of 0.20 percent / day of the containment air mass at maximum internal pressure following a design basis LOCA as given in UFSAR Table 6.5-8.

The time required to reduce the containment enclosure volume and the additional building volumes to a negative pressure of at least 0.25 inches of water is calculated to be 3.64 minutes after signal initiation.

The sizing of the high efficiency particulate air filters (HEPA) and charcoal absorbers is based on the volumetric flow rate required to maintain the negative pressure in the containment enclosure annulus and connected penetration and engineered safeguard areas, and for fission product removal capability employing the conservative inventories given in UFSAR Section 15.6.5.

The CEEACS is a seismic Category 1, Safety Class 2 system.

Containment Enclosure Bypass Leakage The maximum allowable leakage form the containment structure following an accident is 0.15 t

percent of the mass ofits atmosphere per day. This would occur at maximum internal pressure.

During the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months following a Loss-of-Coolant-Accident (LOCA), the containment heat l

removal systems reduce the pressure, the driving force behind the leakage, to less than one-half the maximum value.

Although, the CEEACS has been provided to minimize leakage to the environs, a significant number oflines penetrate the containment and terminate in areas not treated by this cleanup system. Therefore, all leakage attributed to penetrations and to isolation valves, requiring Type B and Type C leakage testing per 10 CFR 50, Appendix J,is conservatively assumed to bypass l

the cleanup system.

l The total allowable leakage fbr Type B and Type C tests and for combined bypass leakage is 0.60 La.

LOCA Radiological Consequences i

The Fission Product Release. Conservative Analysis is discussed in UFSAR 15.6.5.4.a.4.(a).

The primary containment structure is assumed to leak at 0.15 percent / day ofits volume for the first day following the accident, and at 0.075 percent / day thereafler.

Primary containment leakage (with the exception of the 60 percent bypass fraction) is to the I

annulus region between the primary containment and the containment enclosure building.

Tlic doses from this phase of the loss-of-coolant accident are presented in UFSAR Table 15.6-21.
