O 1.0 :umary n reactnr builuirc contairment inte. rated leak rate test (ClLRT) was mncuct oa on Jequoyan duclear Flant unit 1 March 13-16, 1979 Tne measured leak rate for the reduceu-pressure ClLRT was 0.00264 percentace of containment air tass per day, while the upper confidence limit was 0.00S76 percentage of containm2nt air mass per dry. The measurcu leak rate for the full-pressure CILRT was 0.03804 percentage of contairment ai nass per day, while the observed upper confidence limit was 0.0L008 Lercentage of containment air mass per day. This value repre,en% less than 22 percent of the allowable 0.1672 percentage of conta r ent air ra ss per day (0.75 L;1). An analysis of the anta clearly indicates that fully satisfactory results can be obtained for test durations significantly less than 24 hours. E.O Int ro :uction Ar prer rited in bequoyah technical specification 4.o.l.2, the leakr7e ci air f rcm t.ne bouncary forming the reactor building primary containment is limiteu to 0.25 percent by weight of the containment air mass per

           . hours at a pressure of F3 , 12.0 psig. In conformance with Title 10, de of f eueral Regulations, Part 50, Appendix J, Sequoyah technical "pecifications require that reactor building integrated leak rate tests o

performed as a part of the startup and the surveillence programs to memenstrate the continuin; leak-tight integrity of the reactor buildin6 grimary contair=ent. preeperational reactor building ClLRT was successfully completed cn Eequoyan unit 1 b; personnel of the Tennessee Valley Authord ty on March lo, l$) . This test was conducted in accordance with a plant-approved p rure rn io:: 21 test instruction, TVA-2A, which is on file at the plant site. This test instruc tion i=plements the requirements of Sequoyah unit 1 technical specifications end Alpendix J to 10CFR50. The American National o t,a n ua r; for Containment Testin6, ANSI N45.4-1972, r.ud the proposed American nuclet > Society Standard for Containment Testing. 3-274, provided guidance for the crocedure implemented ( the preoperational test instruction. Jesuoyan unit 1 is a 3,411-Ed, pressurized-wat<r reactor employing an ice condenser suppression containment. The Final Safety Analysis Report defines

      *
          .e eniculateu peak accident pressure, -a, to be 12.0 psi6 . The reactor m m ainc contaircent is divided into four major compartments--the lower ice ec+ denser ccanartment which houses the energy-absorbin6 ice beds, the upper ice concenser compartment which encloses the support equipment for the ice concenser cycten, the lower compartrent which contains the reactor and the main pipim systems, anu the upper compartment which provides for a large work aren within contairment and also can accommodate the displaced air m ra from the otner compartments in the unlikely event of a loss-of-coclant

accident (LOCA). These four compartments are connectea by means of olowout panels located between the lower compartment and the lower ice condenser cogartment and between the upper compartment and upper ice concenser ecmpartment. In the event of a LCCIs, steam flows from the lower cc:partment through the ice condenser compartments and through to tne uner compartment. The uprer compartment is sealed from the lower compartorit to ensure that any steam released in an accident will be forces through tne energy-absorbing ice beds. For the performance of this CILHI, the lower and upper compartnents were not sealed in order to allow the free flow of air in containment as would exist in a post LOCA con di tion. Tnis report outlines the objectives, principal events, special equipment used, ani analysis of the test results for the CILhT cocpleted on March 16 on Sequoyah unit 1. 3.0 Test zurpoce aM nesults 3.1 Tect lurpose ihe cojective of the preoperatior.al CILRT performed on Sequoyah unit 1 rac fivefold. The principal objective was to demonstrate the lea.<- Lignt integrity of the reactor buildin6 contaircent for power operation. For Sequoyah u11t 1, the leak-tight integrity is defined by technical specification 4.6.1.2 to be that leakage of air from containment not to exceed 0.0078 percentade per hour (0.1872 percentage per day) of contair. ment air cass at a pressure of Pa-

c. probler. unique to preoperational CILRT's is that of possible incomplete construction. Therefore, the second objective was to verify that there were no unidentified openings in the containment vescel.

Jhe third ocjective of this CILRT was to evaluate a technique of mocelinc a ralticompartment ice condenser pressure suppression ecn:airment. '"his was accomplished by usin6 a computer-based data acquicition system that collected data from a number of sensors A.ich sampled containment atmosphere in each of the four compartments. Jhe fourth objective was to evalue.te the possibility of accurately censuring the contairment leak rate in a shorter period of time. Lince temperature effect on con ainment curing a CILRT coulc have a

              ,ignificent bearing on test results, th-   fifth objective was to exanine the effects of day / night cycle emperature differences on the results of the CILRT.

32 Test Results TP. leakage rate measured durin the reduced-pressure CILdT was 0.00011 percentnge of contairment air mass per hour (0.00264 percentage per day) at a pressure of P (3.0 psig). The observed 9y-percent upper confidence limit (UCL for this measured leak rate wuc 0.00024 percentage of containment air mass per hour (0.00576 h() percentage per cay). 44/ 008

After completion of the reduced-pressure CIMT, a supplemental forced leakage verification test was conducted to check the results of the CI MT. n forced leakage rate of 0.00494 percentage of containment rass per hour was imposed on the contaiament. The leak rate measured for the 4.8-hour verification test was 0.00570 percentage of containment air rass per hout. The leakage rate measured in the 24-hour full-pressure CIMT was 0.00162 percentage of containment air mass per hour (0.03864 percenta6e per day) at a presrure of P (12.0 psig). The observed 95-percent upper confidence limit (UCLIforthismeasuredleakrate was 0.00167 percenta6e of containment air cass per hour (0.04008 percenta6e per day). This measured leak rate represents less than 22 percent of that allowed under technical specification 4.6.1.2. These values include the leakage measured from types B and C tests from testable lines that were in service during the CIMT. Table 1 lists the lines that were in service during the test. After the coupletion of the full-pressure CIMT, a supplemental forced leakage verification test was conducted to check the results of the CILhT. A forced leaka6e rate of 0.00677 percentage of containment mass per hour (0.16248 percentage per day) was imposed on the cont,ainment. The leak rate measured for the 4 90-hour verification test was 0.00769 percentage of containment air cass per hour (0.17112 percentage per day). Agreement as prescribed by Appendix J between the CILRT and the verification test was -0.0668 Lg , which is well within tha 30.250 La required by technical specifications.

          .io leakage paths other th.n those identified as part of the types B and C test program were found in the performance of the CIMT or the supplemental verification test, ovaluation of the CILRT performed on Se ,aoyah unit 1 conclusively mmonstrates tha t accurate results can be obtained while reducing the time requireu to conduct the test. The technique of using a multi-corpartment model for the ice condenser suppression accurately ccacured the leak rate. The < y.puter-based instrumentation provided reliable and immediate calculations of test results. Section 6.4 of inta Analysis suggests that, for a test duration of considerably less than 24 hours, the teet results are essentially unchanged.

ricure 1 indicates that there were no significant fluctuations in ne containment vessel cetal teg erature. The total O fference in temperature for the 24-hour period during the test was approximately 10F. This small temperature difference of the vessel metal temperature sucgests that the day / night cycle has a negligible effect on the test results of tne CIIaT. L.0 Conduct of Iest i riar to tne pressurication of 'ne reactor building containment for the ctruc tural integrity test (CIT), local leak rate tests (ILRT's) were rerfor" in accoracnce with section 6.2 of the Sequoyah Iiuclear Plant FSM. @ 44/ 009

                                    @ All tests were concucteu using T/a-prepared and plant-approved preoperational test procecures--T'/A-2B for testable penetrations, T/A-2C for testable containment isolation valves, and TVA-3 for the containment personnel air locks.

Ali LLET's were performed prior to the start of the SlT with the exception of those noted in table B.2 of Appendix B.

  .ulvec 3J-26i, 22-2')7, and 32-377 were not installed prior to the performance of the SlT. Since only the outboard valve on each penetration serveu as the isolation boundary, 02e valve alignment was conservative.

Cince the conclusion of the test program, these valves have been installed, testea, and all acceptance criteria met. r'icure 2 depicts the sequence of events for the test program.

_7_ 5.0 . 'surements ani Calculations S.1 lest Cquipment I.a ice condenser reactor containment is unique in the fact that containment uesign pressure is only 12 psig. Tais low pressure requires more accurate instrumentation to detect leakage to the same degree as for conventional containments with design pressures of 50 to 60 psig. For the Sequcyah unit 1 CILRT, the instrus.cntation consisted of a larce number of sensors used to measure containment parameters that were used to ca k ulate the final leaka6e rate. Table 2 identifies the parameters meac r i and the sensor specification, l'ressurination for t! e Sequoyah unit 1 CILRT was accomplished by portt. ele high-capacity air compressors, hated at 3,500 SCFM of dry, oil-free air, these compressors brought the containment to t e r. t pressure in less than o hours.

             . rior to the start of the CILRT, all special test equipment was calibrated by the Tennessee Valley Authority Central Iaboratories,
              ;raceable to the National Bureau of Standards. After the installation ol' special test sense      in the containment, each sensor was checked for functional operation. Upon test completion and depressurization, eacn cenror was again checked to ensure adherence to the calibration.

O 9.c Censor location F or the CIL'iT performed on Sequoyah unit 1, the temperature and dew point sensoi lccations were selected so as to equalize the volume fraction of centainment-free air represented by each measurement. Go single sensor for te.~perature measurement represented more than lu percent of the containment-free air volume. Appendix C lists the volu .etric we]Ehting factor for the vapor pressure, pressure, a: . terperature seIsors. Figures 3-8 identify sensor locations. 5.3 Conruter-Based Acquisition and lata Reduction System Co:.tainment parameter measurements for the Sequoyah unit 1 CILRT were maue and collected by a microprocessor-based data acquisition system. This raw data was automatically presented to a portable dnico. puter system for correction to calibration curves and reduction to containment leaka6e rate. Statistical confidence levels of the calculated results were reported automatically to the tert uirector as the data was acquired. Figure 9 depicts the functional relatianship of the acquisition and data anal'/ sis system. AJl calculations performed t,y the minicomputer system were in co.;forcance with the procedures outlined in AUS N-274 (draft). Cource listings for all computer programs are on file with the

      '; . 4 heactor building Ccntainment Mouel an ice condencer pressure cuppression containment presents special problem not normally encountered in ae leak testing of dry containment structures. The pressure suppression design feature requires the reactar buildin6 containment to be divided into distinct compartments, where vastly different temperatures and tapor precsures may exist. While each compartment is vented to the containment atmosphere during the performance of the CILRT, the direct circulation of air it very limited.

Jince an ice condenser conteinment typically exhib' ts a 400F temperature differential between compartments, it it necessary to compensate for compartmentalization so the leak rate is accurately measured. For Sequoyah unit 1 CILRT, a 4-compartment containment model war used to measure the leak rate. The free air mass is calculated individually for each compartment, and containment leak rate is calculated from the st n of the compartmental masses. Each cencor within a compartment is volume weighted for the calculation of coq,artment average tempert ture and vapor pressure. Figure 10 cepicts the four compartments used in the Sequoyah unit 1 reactor buildinc containment model.

 ..C nnalycic of Test Lata The previous sections of this report have identified the principal test oojectivec and results, cutlined cignificant events, and described the cpecial test instrumentation. In this section, problems that influenced tect recul* c are discussed.

           .uulity Accurance V.anual, requires that all tests performed with an instrument be reviewed if that instrument is found out of calibration. Af ter completion of the CILRT, all special test instrtmentation was checked for adherence to the pretest calibration.

Cne precision quartz manometer (PT-3) was found to be out of tolerance. iost test examination of the data revealed erratic behavior of one of the dewcellc, LFE-7. Consequently, the data collected from rT-3 and LPE-7 was rejecteu. /111 results, data, and graphs in this report are the corrected values which do not include the data fro 4 there two instruments.

     .uri:q; the o-psig CILRT, the ice condenser air-handling units were inadvertently tripped, lata from tables 7 and 6, at about cample 80, reflect the correspondin6 temperature increase in the upper and lower it.a condenser compartments. The temperature increase continued until approximately sample 92 in tables 7 anu 8, at which time the air-handling units were placed cacx in service. Howecer, the temperature in the upper and lower ice condenser compartments did not reach the lower initial temperatures. This suggests that the air-handlin6 units did not completely defrost once put back in service.

There were no detectable leaks found during a soap test of all accessible penetrations during the 6-psig CILRT.

c. 12,0-Ecic CILHT rigure 11 $r a graphical representation of the calculated containment leak rate for the 12.0-psig CILRT expressed as a percentage of containment mass.

The craph axes are percentage of air mass 1, waCe per hour versus time. The slope of the least squares fit '. i 2 to these data is the measured containment leak rate. 2igure 12 is a graphical representation of the total mass loss from containment during the 12.0-psig CILRT. The graph axes are containment dry air mass versus time. Figures lj and 14 graphically depict two alternate methods of determining containment leakage--the point-to-point and the total time methods. In reviewing the graphs for the 12.0-psig CILRT, figures 15 and 16 reveal an increase in total mass in the upper and lower ecgartments, while ficures 20 and 23 show a decrease in mass in the upper and lower ice conlenser compartments. Since the reactor building containment was set up to prevent mass influx to containment, a definite flow path within containment is e vi de nt . The slopes of the different mass plots indicate that eis flow pa Lh exists from the lower and upper ice condenser conpartments to the upper compartment and finally to the lower compartment. Simply stated, the mass is going from an area of reater censity (the ice condenser compartments) to one of 1mter density (the upper and lower compartments). adnation of the compartment vapor pressure plots, figures 16, 1), 21, and du, shows that the vapor pressure in all the connartments e;' cept the upper compartment increases. These 21crences are due to the sublimntion of the ice in the ice conlenser compartments and to the water levels of the containment sumps in the lower compartment. @

h une consideration unique to an ice bea suppression containment is the defrost cycle of the air-handlire units for the ice

            <oncenser. Peaks in the graphs correspond to the cycling of 17e air-hancling units. Luring the Sequoyah unit 1 CILRT, the air-handling units on the endwalls of the upper ice condenser cog artment were set on 6-hour cycles. The effects of these cycles can be seen on the graphs but are most evident in figure 21. The four najor peaks correspond to the defrost cycles of the air-handlin6 units.

Figures 22 and 24 sr.bstantiate the assumptic1 of the iceal Cas relatienship for purposes of leak rate ca'culations. o.3 siscuccion of /creement (Verification Test) Appenaix J to lOCFR50 and AIISI N45.4 specify different techniques for the calculation of agreement between the CILRT and its subsequent verification. Appendix J requires the absolute value of the difference Letween the measured containment leak rate with a superimposed leak and the sum of the imposed leak and the measured containment leak rate Le less than 0.25 LA or 0.25 Iq, as applicable. AIISI 45.4 requires his difference be less than 0.25 of the measured containment leak rate with the irposed leak. Common test practice is to set the imposed leak at between 75 and 125 percentage of the maximum allowable leak rate. a preoperational reduced-preccure CILRT presents a unique case since the maximtml allowable containment leak rate is not determincd until both the reuuced- and the full-pressure test sequences are completed. Similarly, since Appenlix J specifies agreement based on the mim' lsnk rate, it is not possibl<+ to dei r,mine whether agreement between the reduced-pressure CILRT and tne subsequent verification is obtained until the full-pressure CILRT is completed. U2rirg the re .tced-pressure CILff, all accessible penetrations were found to be leak tight when tested with a soap solution. All accessible penetrations were acain soap-solution tested during the full-pressure test. Penetration X-ll8, used for a temporary containment depressurization point, was observed to be leaking at 12 psic. Since this penetration did not leak at 6 psig, the ratio of L tm to Ljgt was significantly less than 0.7. The calculated Iq, when used for agreement specified by Appendix J, results in agreement not being obtained between the reduced-pressure CILh"I and the subsequent, verification test. By the procedure recommended in e d.01 545. 4, ocreement between the reduced-pressure CILRT and the subsequent verification test was obtained. lippenuix D details the methods of cgreement calculations. Table 24 compares the agreecent by each method of calculation for the reduced- and full-pressure tests. @ AAl 016

After completion of the test, TVA concluded that the extremely low Iq (0.00008 percent of containment air mass per hour) was an imoractical limit to attempt to meet for the Sequoyah unit 1 surveillance program. Technical specifications for unit 1 have been modified to require that only full-pressure CIMT's may be conducted for future inservice surveillance testing. A subsequent type B test after the CIMT on the permanent flange Ior penetration X-ll8 verified that the leakage from this penetration met all the acceptance criteria set forth in TVA-2B. o.4 Instrumentation Performance One of the prirery objectives of this CILHT was to evaluate the accurate measurement of 9 e leak rate for test durations less than 24 hours. The comparisons in table 25 show that, for test durations less than 24 hours, the leak rate is conservative. This conclusion is further supported by table 24, a comparison of agreement between different lengths of data collection for the full-pressure CI M T. In all cases considered, the agreement was well within the 10.25 required. For future CIMT's, TVA vill seek to further demonstrate the reliability of the techniques outlined in this report while evaluating the possibility of decreasing the time required to perform a CIMT. 7.0 Conclusions The Sequoyah unit 1 preoperational test series results yielded an allowable @ unit leakage limit for reduced-pressure inservice testing lower than practical for conducting inservice reduced-pressure CIMT's. Therefore, all future CI MT's on this unit will be performed at full pressure, Pa. The results of the full-pressure CIMT clearly demonstrate the leax-tight integrity of Sequoyah unit 1. The total leak rate was less than 22 percent of the allowable leak ra.te under Sequoyah technical specifications. The technique of nodeling a culticompartmrat ice condenser pressure suppression containment using a co7 uter vased data acquicition system yielded i=ediate results that accurately measured and displayed containmcnt leak rate. ata analysis shows that, for Sequoyah uit 1, the temperature effects of a day / night cycle cause no significant changes in test results.

          & analysis of the data for this test clearly demonstrates that the test results remain essentially unchanged for test durations of considerably less than 24 hours.

A!+EiklX d ILJtL LEAK RATE TEST C3LiY A. L/p.: + Tests Une nethou .'.ts used to perform the type b tests--the absolute method (prassure uccay). Using air or nitrogen as a test medium, the testable c o lu~.e van pressurized to the designated test pressure. The leakace rate was then determined by a measured pressure drop during a set time specifieu in the applicable preoperational procedures, TVA-2b, Containmenu iescel Pressure and Leak Test - Testable Ienetrations, and T/A-3, containment
.eccel cressure and Leak Test - Ferconnel Air Lock, all testable penetrations, with the exception of those listed in this appendix, ,;ere testeu prior to the perfurmance of the CILRT. These penetraticnn were tested following the completion of the CII2f, and the Irakace rates were added to the total leak rate.
itny p. atrations or hatch covers opened after the completion of the CILnT cill be testea prior to unit startup under the applicable plant-approved surveillance instruction.
i. m = a: of all type B test data is included in this appendix.
B. Wye : Tests
?.co me nous were usea to perform the type C tests--an airflow method and m tater <lisplacemen t method. The airflow method consists of a rotameter flow facility in line with the testable valve through a test connection.
an air supply is connected to the rotaneter facility, which mcacures the flow of air necessary to replace the air leakage past the valve being testeu. Fror this, a leaka6e rate is determined, ihe ' n ter uisplacement method consists of a calibrated water test tank equipp"1 with a siE ht class. A timed water level drop is measured to calculate the leakage past the valve (s) being tested. A separate air cource is used to maintain the water pressure at the prescribed test nressure. Fifty valves were tested with water or a water-glycol mixtt.re am conrcrted to air leaka6e for the first fuel cycle for reasons stateu in table u.2-35 cf the FSAR. The results of these tests and the correspcnainc nir lea:uule rates are noted in the summary of type C cata in this appendix.

The internals of Oe inbcard ccntrol air valves were replaced and, at the time of the CILRT, were no; on site. Therefore, for the performance of the CIIRf, a concer= t i ce vulve lineup using only the outboard isolation valves was used. 9 44/ 10 9
Any raintenance action or repairs on containment isolativn valves subject t.o type C tests which wculd affect leakage from primary containment will ue retectect under the applicable plan;-approved surveillanco instruction terare unit startup.
