1.0 Introduction

The first periodic Integrated Leak Rate Test (ILRT)for the Donald C.Cook Nuclear Plant-Unit 2 reactor containment was successfully completed on May 4, 1981 by personnel of Indiana 8 Michigan Electric Company (18M).The ILRT was performed as specified in surveillance test procedure 12 THP 4030 STP.202, Rev.3 and in compliance with American National Standard-ANSI N45.4-1972,'Leakage Rate Testing of Containment Struc-tures for Nuclear Reactors'nd Code of Federal Regulations 10 CFR 50 Appendix J-'Primary Reactor Containment Leakage Testing for Hater Cooled Power Reactors'. The absolute test method was used on the 3 com-partment containment model developed for both the Unit 1 and Unit 2 Preoperational Integrated"Leak Rate Tests.Data was collected at half hour intervals over a 24 hour test period.This data was used to.calculate the normalized weight of the initial dry air mass remaining in the containment at each half hour interval.The measured Type A leakage rate, Lam, is the slope of a straight line determined for a linear least-squares fit of the calculated normalized weight vs.time.2.0 ILRT Acce tance Criteria The Unit 2 Technical Specifications and Section 5 of the Final Safety Analysis Report (FSAR)define the containment allowable leakage, La, as 0.25 percent by weight of the containment air per 24 hours at a pressure, Pa, of 12.0 psig.The measured leakage rate.Lam, must be demonstrated to be less than 0.75 La, (0.1875'A wt/day)as required by 10 CFR 50 Appendix J.In addition, the accuracy of the leakage measurement must be verified by performing a supplemental test, the results of which are acceptable provided the difference between the supplemental test results and the Type A results is within'.25 La'(0.'0625/ wt/day).As specified in Section 5.0 of D;C.Cook Plant Surveillance Test Procedure 12 THP 4030 STP.202 and in accordance with 10 CFR 50 Appendix J Section III-A,'Leakage Test-Requirements, Type A'ests', the test was considered acceptable when the following criteria had been met: 2.1 The leak rate, as determined by the 95%upper confidence limit of the least squares line, Lam/955 has converged to an'acceptable level: 'Lam/95K (0.75 La-Type C Leakage Penalty}2.2 The duration of the ILRT has exceeded the minimum of 12 hou'rs and the difference between the 954 upper confidence leakage limit and the leakage rate itself does not exceed ,0.0625/wt/day in the most recent data set.Page 1

2.3 The upper confidence level leakage and the measured leakage do not show a negative trend over the last four data runs.The Supplemental Test was considered acceptable when the'following criteria were met: 2.4 The duration of the Supplemental Test meets or exceeds the minimum of 6 hours.-2.5 The sum of the imposed leak, L , and the leakage measured~during the Type A test, L , i3 within+0.25 L of the composite leakage, L , meNured in the supplemental test.(L+L-0.25 L)<L<(L+L+0.25 L)The criteria used for this Integrated Leak Rate Test is more stringent than that specified in 10 CFR 50 Appendix J.These criteria incorporate additional test commitments made by D.C.Cook to the Nuclear Regulatory Commission. These.additional commitments are embodied in a response to guestion 22.14 of Appendix g o'f the D.C.Cook Nuclear Plant Unit 2 FSAR.3.0 ILRT Results 3.1=Leakage Rate Summary: Duration of Type A Test: 24 hours Duration of Supplemental Test: 6 hours A.ILRT'Type A'eak Rate, Lam B.ILRT'Type A'55 Upper Confidence Limit Leak Rate, Lam/95%C.Type C Leakage Penalty Neasured Leakage*'wt 24 hours-0.05287-0.05748-0.015975 Allowable Leakage*X wt/24 hours-0.1875**0.75 La-Type C Leakage Penalty++=-0.1875-(-0.015975) =-0.17153 N/A D.Imposed Leak Rate, Lo-0.2006 0 5 La<Lo<La-0.125<Lo<-0.25 E.Suppl cmental Test=Composite Leakage, Lc-0.24631 N/A F.Supplemental Test-Correlation am (Lc Lo)0.00716 Lam-(Lc Lo)<.25 La**Lam-(Lc" Lo)<~0625 Page 2

The slope of the linear regression line computed for weight remaining in the containment as a function of time is negative since weight remaining in the containment decreases as a function of time.Hence leakage out of the containment is shown as negative in the-table.**10 CFR 50 Appendix J criterion++Test criterion specified by plant procedure 12 THP 4030 STP.202+Guideline proposed by ANS 274 Draft No.1.Item A, L , is the measured containment leakage after 24 hours of tBing data in one-half hour intervals.

Department Interfaces -Contacted as required to complete test requirements. 4.2 Lo of Times and Events Having satisfactorily completed the installation and checkout of all test instrumentation, a successful containment inspection, the valve line-up.initial conditions, and all other test pre-requisites, pressurization 'of the containment was initiated. Pressurization of the Unit 2 reactor containment began at 0530 hours on May 1, 1981.Containment temperatures, pressures,'nd vapor pressures, and ambient temperature and barometric pressure were logged on an hourly basis.Each data set collected were assigned a'Run Number'tar ting with Run 81 at 0600 hours.At 0130 on May 2, 1981 pressurization was terminated at a pressure of 12.4932 PSIG (Run 25 P).During the pressurization period two separate entries were made into the containment instrument room to work on dew point hygrometers. Rewiring of the hygrometer readouts corrected the hygrometer problems on all hygrometers except VPL-2.It was decided just prior to the end of the pressurization period to run the test without this redundant hygrometer.

• Throughout the remainder of the test YPL-I was used alone for lower volume dew point.The stabilization period was initiated at 0200 on May 2.After the minimum period of 4 hours, containment temperatures were monitored closely to determine when the stabilization criteria had been met.Stabilization criteria defined by procedure 12 THP 4030 STP.202 are: a.The duration of the stabilization period has exceeded the minimum 4 hours.b.The containment has been maintained at a pressure of 12.0 (+0.5,-0.0)psig for a minimum of 2 hours.c.The weighed average temperature in the Upper, Lower, and'Ice Condenser compartments has not varied more than 0.1'F/hr over the last four (4)hour period.d.No single Upper, Lower or Ice Condenser compartment temperature reading has changed more than 0.5'F during the last hour of the stabilization period.Page 8 ij At approximately 0300 it was discovered that a heater was energized on HV-CUV-2 which was running.This heater was secured and all ventilating units in the containment were started to try to circulate air to improve the temperature distribution.

tlost of the fans tripped off due to thermal overload after about one hour and were left off.All fans were secured at about 0530.After 15 hours all of the stabilization criteria were met and the stabilization period was declared over at 1700 on Hay 2, 1981 (Run 31S).The'Type A'est was begun at 1730 on Hay 2, 1981 with a containment pressure of 12.3799 psig.Preliminary leakage cal-culations performed for the stabilization period had indicated that the'Type A'est criterion had already been satisfied. It was now just a matter of continuing the half-hour data collection intervals until the minimum 24 hour time requirement and other self imposed criteria had been met.After 24 hours of data collection the'Type A'est was declared successfully complete.(Run 49T).After Radiation Protection drew a sample of the containment air for analysis, air was bled from the containment through a cali-brated rotameter. This leak rate was established at 3.1 scfm (.2006 wt I/day)which is in accordance with the Unit 2 Technical Specifications (quantity greater than 255 of total measured leakage at Pa)and the guidelines of ANS 274 Draft 1 (.5 L L<L).At the completion of the minimum 6 hours of dat3 c8lleciion the supplemental test and the ILRT was declared successfully complete.The supplemental test showed a correlation between the measured leak and the imposed leak of.03 L , well within the requirement of less than.25 L.The contaikment was subsequently depressurized and sy'stems were restored to normal as required by plant operations.

5.2 Instrument

S ecifications The instrumentation used during the ILRT is shown in Table 5.1.Each of the instruments shown here was supplied with calibration performed within 6 months of the test and traceable to the National Bureau of Standards. Calibration conversion formulas and corrections were preprogrammed into the ILRT computer program to allow direct input of all pressure, temperature and dew point instrument readings.Two precision t3ensor quartz manometers were used for redundant measurement of the pressure in each of the upper, lower, and ice condenser compartments of the containment. A seventh was used to moni tor atmospheric pressure during the test.The three containment compartments were instrumented with a total of forty-six.(46) 100 platinum RTD sensors.The upper, lower, and ice condenser compartments contained 16, 23 and 7 sensors respectively. Each sensor is located to represent the temperature of a unique sub-volume within its compartment. The sub-volumes collectively represent the total volume of their respective compartment. Each RTD reading is converted in the leak rate computer program to temperature in degrees Fahrenheit. Each temperature is weighed by the fraction of the total compartment volume contained in the sub-volume the RTD represents. The sum of the weighed temperatures in each compartment is the weighed average temperature of that compartment. Page ll

Six Cambridge Dew Point Hygrometers were used for monitoring compartment dew point temperatures for the determination of vapor pressure in the leak rate computer program.They provided redundant measurement of dew point in each of the lower containment, upper containment and ice condenser. The Unit 1 and Unit 2 preoperational tests used only 4 hygrometers, 2 i n the lower volume and one in both the upper and ice condenser volumes.For this test, two hygrometers were added for the upper and ice condenser volumes.The original 4 hygrometers are the t1odel 8992 dew point hygrometers used in the Unit 1 and Unit 2 preoperational tests.The new)1odel 8660 hygrometers are improved and more compact than the Nodel f992.They all operate on the same principle. The air sample is drawn through instrument lines across a mirrored surface of which the temperature is controlled by an optical feedback circuit to precisely the point at which a dew (or frost)appears.The mirror temperature is measured by a platinum RTD imbedded in the body of the mi rror.The sensor and control units were located inside the lower containment volume so that the samples would be maintained at the containment pressure.The er ror associated with each individual dew point measurement is+0.5 F.The addition of redundant measurements did not significantly affect the error of the overall dew point temperature measurement system.Page 12 1J A Brooks rotameter was used in the supplemental test to measure and maintain a constant flow rate for the imposed leak.It was calibrated in the range of 0.6 to 6 scfm at 14.7 psia and 70 F with an accuracy of+1.05 of Full Scale.The actual inlet temperature and pressure for the supplemental test were 63.7 and 18.8 psia.The temperature was measured using ETR-133 which is in close proximity to the end of the rotameter inlet line inside the lower containment. Pressure was measured at the inlet to the rotameter itself using a 0-30 psia Heise gage.The temperature and pressure readings were used to correct the indicated rotameter readings to standard conditions using the following relationship: Wcorr=Wind X+T ETR-133 X Gage atm 14.7 Wcorr Wind ETR-133 atm Corrected rotameter flow in path Indicated rotameter flow in cfm Rotameter inlet temperature,'Atmospheric pressure, psia 5.3 Sensor Locations The locations of the sensors used for this test were identical to the locations originally specified for the Unit 1 and Unit 2 preoperational ILRT's, Figure 5.2.1 (MSK-78C)shows the location in section views of the containment. 5.4~A The inaccuracies associated with the use of the test instrumentation package used in the Unit 2 Preoperational ILRT in measurement of the containment leakage rate was determined to be+0.076 L.A copy of the analysis calculation is contained in the Unit 2.Preoperational Integrated Leak Rate Test Report.In terms of the impact on this error analysis only insignificant differences exist between the instrumentation package used in the Unit 2 Preoperational-ILRT and the package used, in this test.The error analysis and the+0.076 L result obtained for the Unit 2 Pre-operational ILRT Ts considlred to be also representative of the modified instrumentation package used in this test.Page 13

5.5 Containment

Pressurization A aratus As in the Unit 1 and Unit 2 Preoperational tests, the plant air system, in conjunction with test pressurization filters and driers, were used for pressurizing the containment. The air enters the containment at approximately ambient temperature and a dew point of approximately -20'F.The air enters the con'tainment through a spare penetration in the upper volume.A valve is provided at the penetration outside the containment, where the air line can be isolated and closed with a blank flange.6.0 Containment Model and Leak Rate Calculation The containment leak are performed by the'absolute'ethod on a'total time's described in AHS-N45.4-1972. The containment design pressure is 12.0 psig and allowable leakage (0.75 La)is 0.18755 wt/day.The containment model and leakage calculations used to perform this test-are essentially the same as the ones used in the Unit 1 and Unit 2 preoperational tests.A 3-compartment model is employed for the calculation of the containment leak rate.It was developed to accommodate the distinct and widely varied envi ronmental condi tions existing in each of the Upper, Lower and Ice Condenser Volumes.The normalized fraction of the initial containment dry air mass, W , is calculated on a compartmental basis by ratioing the sum ofnthe product of each compartment's dry air density and compartment volume fractions as determined from data collected at time t , to the same value deter-mined from the initial data collected atntime t.0 Expressed in equation fons: 1 Wn=K WF un Un+VWF Ln Ln+VWF P-VP P-VP u Tun L T PIn-VPIn TIn 1 R VWFU Uo Uo+VWF Lo L+VWF Uo Lo Io-VPIo TIo Page 14 Ip li Where: W=normalized weight remaining in containment at time t (dimensionless) n f t-1 bs R=gas constant for dry air=53.34 ibm-'R (The terms cancel)VWF=Volume Weighing Factor (Each compartment volume is ratioed to the Lower Compartment Volume)(dimensionless) P=Compartment Total Pressure (psia)VP=Compartment Vapor Pressure (psi)T=Compartment Weighed Average Temperature (degrees Rankine)Upper Compartment Lower Compartment Ice Condenser Initial Time time at nth data collection

Containment Tem eratures Containment temperatures are used to compensate the weight remaining calculation for total pressure changes caused by the thermal expansion or contraction of the containment atmosphere. It is recognized that temperature gradients exist in the containment and temperature changes will not necessarily be uniform throughout the containment. Therefore the containment Page 17 is instrumented with 46 temperature probes, located such that each monitors a fraction of the total containment volume.In the establishment of temperature sub-volume boundaries and temperature probe location, consideration was given to the location of physical thermal barriers and heat sources and sinks.The sub-volumes are generally different in size as well as shape, thus, in determining average containment temp-erature, temperature readings are weighed as a function of the volume fraction they represent. The weighing of temperature readings occurs on a compartmental basis.The weighted average temperature in a compartment is given by the following expression.

Referring to Table 6.5.1, the value K of the t-distribution, as determined from the point at which the cumulative dis-tribution of the t-distribution has the normalized value~/2, defines a two sided interval about the mean of o(nu)independent measurements the entire population of measurements exist to a confidence of 1n.The t-distribution is normalized such that its mean is zero and the standard deviation is one.This allows K(v,a)to be applied directly to the mean, x, and standard deviation s, of any sample U independent measure-ments representing a normally distributed population. The confidence limits are expressed as x+K(u,a)S.In the application of this statistical method to the leak rate test, the slope of the least-squares line, b, is the'mean'a/ue of the leak rate and the variance of the'mean', S , is given by: n S=E (W.-(bt.+a))b i=1 n where, t=E t.l=l Page 20 t I, Oh>>)Oa>>TABL~6,$, l DISTR!St TIOlS OF g O>>Sr>>ca of freeclocn K o K 0.10 Probabilicy o 0.0$I 0.0l l 0.001 I 2 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 60 120 6314 2.920 nM3 2.132 XOI5 1.943 1 JL95 1.860 I JU3 1.8'12 1.796 1.782.1.771 I 761 1.753 1.746 I 740 1.734 1.729 1.725.1.72l 1.717 1.714 1.711 1.708 I.r06 1.703 1.701 I.&99 1.697 1.684 1.671 1.658 1.645 12.706 4305 3.182 2.776 5571 2.447 2365 2306 2262 222S LAI 2.179~2.160 2.14$2.131 2.120'.110 2.101 2.093 2.086%080 2.074 2.069 2.064 2960 2.056, 2.052 2.048 2.045 2.042'.021 2.000 I.980'.960 &3.657 9.925 5.841 4.604 4.032 3.'707 3.499 3355 3250 5.169 5.106 3.055 3.012 2.977 2,947 2.921 23198 2.S78 2.S61 2445" X$31 ZSI9 2307 2.797 5787 2.779 Z.r 7I 2.763~2.756 L750 2.704 2.&60 2.617 Zi76 636.619.31398 IÃ941 8.610 6.859$.959 5;405 5.041 4.781 4387 4.437 4318 4221'.140 4.073 4.015 3.965 3.922~3.88)~3.850 3.819 3.792 3.767 3.745 3.725 3.707 3.690 3.674 3.659 3.646 3851.3.460)373 3491 icua mblc Sires the>>aloes of c corresponding to>>ccsnus>>aloes o(the prooabiiicy o 0>>eel of silnifceancel ofa random eaciablc iaUin9 cnsccte che shaded areas inthe Rlscre.for a ci>>cn number of dryrees of free dom raeaihblcforcheccticnacicm of error.For a onnudcd tcs chcennfcdcncc0rnftsareobtaincd for ocr ihistablciscahcnfromiaoic ill of Fisher fs Yaccsc Sccruoorf i>>kkc j>>r Bi>>f>>fcrcf.

Hence, v=n-2.1 1 The value of a used is that which corresponds to a 90/two-sided confidence interval which is equivalent to a 1-a/2 or 95Ãone-sided interval.The value of a is therefore 0.1.Now, the upper confidence limit of the leak rate, b, is expressed as: b-K(n-2, O.1)=Sb The negative sign defines the upper limit since the value of b is negative.The Leak Rate Com uter Pro ram'LRTEST'he leak rate computer program,'LRTEST', has replaced earlier versions of the two programs used in the Unit I and Unit 2 preoperational test, know as'CCVDREP'nd 'CCVREPT'. 'LRTEST'ncorporates the revised statistical analysis discussed in Section 6.5 and an added degree of flexibility that its predecessors lacked.'LRTEST'ccommodates the operator input of certain'fixed-data': the calibration conversion and correction coefficients of the present instrumentation system, and the volume and temperature weighing factors., The fixed data represents that which is fixed for the duration of one ILRT, but will vary from one ILRT to the next.'LRTEST'eceives test data from a card reader.The raw test data collected for each test interval is coded onto input data coding sheets and punched on to computer cards.The data includes the data run number, the elapsed decimal time from run 81 in hours, the 46 containment temperatures in millivolts, seven pressures (6 containment, 1 barometric) in psia, and dew point temperatures in millivolts. The data cards are accumulated in a deck in the order of the run numbers.The program establishes a file for the raw data and computes values expressed in the proper engineering units.The program computes the average compartment and containment pressures, the containment pressure relative to atmospheric, the weighed average compartment temperatures, and the average compartment dew point temperatures. From the average dew point, the vapor pressure is calculated using the Goff-Gratch formulas for saturation vapor pressure over water or over ice.Page 22

For each run of the computer program, the raw input data and the above computed values are summarized for the most recent data run.This is a valuable aid to input data error checking and analysis.Also, at the option of the program operator this summary may be printed for an operator-specified range of runs ending with the last data run.A separate summary of average compartment pressures, temperatures and vapor pressures is also printed for either all the runs entered into the program, or for all the runs in a range specified by the operator.The elapsed time printed for both the individual run summaries and the overall summary is controlled by the starting point of the range.After three data runs have been made or three runs are available in the user specified range, (a minimum of three runs is required to perform the least-squares and statistical analysis)the program calculates the leak rate and 95%upper confidence limit of the leak rate.In addition, the program calculates the remaining weight of the containment, and of each compartment. The remaining weights in a compartment 'c', is given by the following: .P-PV cn cn cn cn P PV co The individual compartment remaining weights are used only as an aid to data interpretation.

8.0 Data Anal sis and Summaries This section of the report contains graphical analysis of data obtained during the conduct of the ILRT.The'ILRTEST'rogram summaries of average containment temperatures, pressures, and vapor pressures, and leak rate calculations appear in Section 8.2 of this report.Past test experience has shown that the instrumentation package used for this'est is quite capable of measuring the leak rate accurately, as evidenced by the rapid convergence of the 95Ãupper confidence limit of the leak rate and the excellent correlation of results between the'Type A'nd the Supplemental Test.The error analysis for the instrumentation system predicts+0.0195 wt/day, and this test correlates well within that interval.8.1 Gra hical Anal sis Figure'8.1.1 is a plot of containment weight remaining vs.time for the Type A Test, the slope of the least-squares line is the calculated leak rate.A second line is drawn using the vertical intercept of the least-squares line and a slope corresponding to the 955 upper confidence limit leakage.A line corresponding to the allowable leak rate (0.75 L)is also shown to illustrate the relatively wide margin 5y which the leakage criterion was met.Figure 8.1.2 is a plot of the containment weight remaining vs.time for the Supplemental Test.The slope of the least-squares line is the composite leakage rate (L).Using the vertical intercept of this least-squares line, two additional lines are drawn corresponding to the Supplemental Test correlation limits[(L+L+.25 L)>L>(L+L-.25 L 0].Page 32 4 I.f>ik I tooooo k.~<<t-I 4 4 J I~D.CICooK Pcrrur Vivre 2'/RT,/Ay/'78/Tr<E 8'@sr Cavrwurrzur Wester Re~we vs.7i~r'0 8-k-!JO!O 0 0 8 8 i I 1 0499/"!0 PMEJ9 lrAK'-I I'~00 Co/vrrortacs';',.RArr0 00 Lrwsr Sovt9zrs 4'J're Twas R'rsr.78'0 99)DO/0 IE ECSWun 7ine-h'49'o Page 33 1I 4!li)O 4~1 4 4+4 1 O.C.CoOA PSAAIr.UkIT c Z'I,RT,.PAT I'IBI!Surr Zenana>P.riSI!COPITAIAlnEP7 LVEIGk QEftAIIJIIIJI'4 VS.7IIIII 4j.!JJJ i g 4 4 0[->==PP t l 1 4, 4 4~o E/M (MIISS IITA J~4!x~0 V 4'4-.1 PL EnEA(Th CoZASJ!4 4 I-, 4'4,'4 IO/8'ZuerwcaXuia's ., Page 34 'f I y 8.2'LRTEST'ro ram Summaries D.C.Cook Unit 2, Integrated Leak Rate Test April 30-May 4, 1981 8.4.1 Fixed Pro ram Information ~Pa e 8.4.2 Pressurization Runs 1P-25P Summary of Averages 8.4.3 Stabilization Runs 1S-31A Summary of Averages Preliminary Leak Rate Analysis 8.4.4'Type A'est Runs 1T-49T Summary of Averages Type A Leak Rate Analysis 8.4.5 Supplemental Test Runs 1Su-13Su Summary of'verages Supplemental Leak Rate Analysis Page 35 THIS IS A CHLCV, OF T>(j IHOIJT l)ATA PTn HILLI-vOLI I(>I'Af<<F<>><f.

Leak Test Pro ram 9.1 Past Test Results Summar Local leak tests have been conducted periodically on Unit 2 in accordance with guidelines specified in 10 CFR 50 Appendix J, the FSAR, and the Plant Technical Specifications. Testing is performed under plant procedure 12 THP 4030 STP.203,'Type B and C Leak Rate Test'.The program consists of'Type B'ests designed to determine leakage through the containment electrical and pipe penetrations, air lock door seals and overall air lock leakage, and'ype C'ests designed to determine leakage through containment isolation valves.Table 9.1.1 summarizes the test results for Type B and C testing performed since the Unit 2 Preoperational test.The leakage detection instrumentation used in the conduct of the'Type B and C'ests is certified, traceable to NBS, and calibrated pr ior'to the tests.The instruments consist of 4 cali brated flow meters, of different ranges, connected in parallel.A test is performed by isolating a test volume bound by the containment isolation barriers under examination. The test volume is pressurized to 12.0 psig.A regulator in the air supply line to the leak rate monitor maintains the test volume pressure at 12.0 psig while the flowmeters measure the air flow required to maintain this pressure.This flow is equivalent to the leakage out of the test volume.Exact test pressure and temperature is recorded and used to convert the measured leakage to standard conditions.

I nition S stem DI S Instrument Room Isolation Our review of the communication paths between the instrument room and the lower volume subcompartments has revealed that limited communication exists through several small openings and a number of pipe sleeves which are not sealed.Therefore, the DIS design described in Attachment No.2'o our AEP:NRC:00500A letter has been modified to include two'additional igniters (one per train)in the instrument room.These two additional igniters will be installed~,}n Unit 1 during the current refueling outage and in Unit 2 during the next ice weighing surveillance shutdown (late 1981)(See Section 3.0 below for a discussion of Clasix results).Thus, the Cook Plant DIS will employ a total of seventy (70)igniters per Unit.1.2 DIS Technical S ecifications, 2.0 Proposed Technical Specification Table 3.6-1A, submitted by our AEP:NRC:00500C letter dated May 29, 1981, has been modified to reflect the addition of two igniters (one per train)in the instrument room.Revised pages reflecting this change for each Unit of the Cook Plant are contained in Attachment No.4.Ice Condenser Insulation s The ice condensers in Cook Units 1 and 2 are very similar to those in McGuire and Sequoyah-. ,However,, instead of polyurethane foam, fiber-glass encapsulated in polyethylene bags is'mployed in the Cook Units for insulation purposes.The insulation is'ocated between the con-tainment wall and the crane wall and the air handling ducts, and is covered by galvanized steel sheets with joints between panels sealed to prevent vapor penetration. Fiberglass exhibits very stable material characteristics even at high temperatures. Existing data indicate that fiberglass begins to'soften(1) at about 1350oF, and that significant decomposition is not expected except at much higher temperatures. The other component which makes up the insulation assemblies is polyethylene sheets.The thickness of these sheets is about 6 mi ls.Review of existing literature on the thermophysical properties of polyethylene shows that.significant degradation (greater than a few percept per hour)has been observed at temperatures in excess of 700oF<).The energy content of polyethylene is reported to be about 1.3x104 BTU (3f P~J~At 1 I 0 Recent analysis performed for the Cook Units using the modified CLASIX code predicts upper plenum temperatures of approximately 1100oF for short durations (see Attachment No.2).Burns in the upper plenum exist for no more than 10 seconds.The shortest interval between burns is approximately 60 seconds.The Cook temperature profile of the upper plenum generated by CLASIX is similar to that of Sequoyah.Using the CLASIX results at the upper plenum as temperature inputs, TVA has calculated the heat-up rate of equipment, such as igniter assembly box and cable within condui ts, in the region and found that the inside surface temperature of the metal casing does not exceed 270oF.Therefore, it is reasonable to believe that, due to the similarity between th'e transient temperature input data for Cook and Sequoyah, the results obtained by TVA can be used as a good approximation for the inside surface temperature of the galvanized steel cover on the insulation. Given these conditions at the upper plenum, the insulation behind the steel covers is not expected to be exposed to temperatures which might lead to sub-stantial amount of polyethylene degradation. Calculation of the energy content for all the polyethylene in the upper plenum reveals that there would be about 7x106 BTU re-leased into the containment even in the unlikely event of its complete decomposition. This amount of energy is.less than forty percent of the energy calculated by Duke Power for the'ntermediate deck doors and is less than ten percent of the energy generated from hydrogen combustion for a typical CLASIX analysis.Moreover, based on the heat transfer calculations performed on insulation heat-up in the ice-bed region by Duke Power for the McGuire Plant, the temperature of the surface adjacent to the insulation is estimated to be about 370oF.Due to the similar configuration of the Cook and McGuire ice condensers, the heat transfer results reported by Duke are applicable to Cook.Hence, the polyethylene in the ice-bed region of the ice condenser is not likely to experience substantial degradation under these predicted conditions. Therefore, despite the fact that a different type of insulation is used at the Cook ice condensers, it appears that the potential impact of insulation degradation on the containment is similar to that of McGuire and Sequoyah.3.0 CLASIX Code Results Attachment No.2 to this submittal contains the preliminary results of a Cook-specific CLASIX analysis utilizing passive heatsinks, a fan flow/head curve and a separate nodal volume representation ~I V@I (p~I.of the ice condenser upper plenum.This analysis indicates that the peak pressure due to hydrogen combustion remains below the containment design pressure.As expected, no combustion occurred, in the upper volume, the fan/accumula'tor rooms, or'he dead-ended volume.A total of thirty seven (37)burns are predicted; seven i.n the lower volume and thirty in the upper plenum.Slightly less than one million pounds of ice remain at the completion of the transient.

4.0 Containment

Air Recir culation/dro en Skimmer (HYS)Fans V The results of the CLASIX analysis mentioned in Section 3.0 indicate that maximum differential pressure between the fan/accumulator room and upper volume'of 2.5 psi;with the higher pressure existing in the upper volume.In the cours'e of our investigation of the fan survivabi li ty,'e have identified a potential failure'echanism due to the possible development of a differential pressure across the'fan housing when the upper compartment pressure is greater than the fan/accumulator room pressure.In such case the fan housing could collapse.l<e are investigating various modifications to the HYS fans which would eliminate this concern and will report to you on the schedule for the completion of the selected modifications in a later submittal.
