1.0 INTRODUCTION

The Pre-Operational Integrated Leakage Rate Test (ILRT) for the Donald C. Cook Nuclear Plant - Unit 2 Reactor Containment was successfully completed on October 2, 1977 by members of the Indiana and Michigan Power Company and the American Electric Fover Service Corporation. As per FSAR and Technical Specifications the containment allowable leakage rate L is limited to 0.25 percent by weight of the a containment air per twenty-four hours at a pressure F f 12.C a FSIG. In conformance with the criteria specified in Appendix 'J' of 10CFR 50 this allowable leakage is reduced to C.75 L which is a equivalent to -C.lc75 percent by weight per day. The ILRT was performed as specified in the I&M approved Fre-Operational Test Procedure 2 F0-c33-33' written by AIFSC. The American National Standard - ANSI UL5.'+-1972-Leakage Rate Testing of Containment Structures for Nuclear Reae:crs and 1CCFR 50; appendix 'J ' were used as guidelines for the procedure as well as for the associated leak rate calculations. The absolute test method was used to calculate the leakage rate using data taken every thirty minutes for thirty-one and one-half hours. The normalized weight of-original air remaining in the containten determined from these calculations was plotted agains: time and a statistically averaged leakage rate in per cent by weight per day vas obtained by a linear least-squares fit to the resulting graph. Following the thirty-one and.one-half hour test, a Supplemental Test was performed by imposing a known leak on the centainnen: Oc verify the validity of the original measurements. O

2.0 IUTEGRA.TED iEAK RATE (TYPE '.'i TEST ACCEFTAUCE CRITERIA 2.1 as spec;fied in Section 6.C of D. C. Cook Nuclear Plant Fre-Operational Test Frocedure 2 FO-c33-334 and in accordance with 10CFR 50; Appendix 'J' requirements for Type 'A' leak tests, the test was considered acceptable when the following had been verified: 2.1.1 The measured leakage rate (LAM), as determined by a linear least-squares fit to a graph of calculated points, proves to be less than 0.75LA as specified in the D. C. Cook Nuclear Flant - Uni: No. 2 Technical Specifications. 2.1.2 The accuracy of this test has been verified by performance of the Supplemental Test. The measured leakage rate (LAM) is validated when the difference between the leakage rate L'AM, determined from the Supplenental Test, and the leakage rate LAM, determined frem the linear less:- squares fit to the graph cf calculated peints, is within = 0.25 L. n . a

C. Cook Nuclear Plant FSAR and Technical Specifications. The containment integrated leakage rate reported here was determined frem data recorded during the September 3C . I

i 32 Discussion of Type 'A' Test Results (Cont'd' through October 2, 1977 performance of I&M Pre-Operational Test Frocedure 2 F0-033-334. A discussion of the mathematical and statistical treatment of this data to yield the containment leakage rate may be found in Section 6.0 of this report. Item 'A' of the Leakage Rate Summary is the measured containment leakage determined after thirty-one and one-half (31.") hours of data taking, recorded at thirty j minute intervals. The measured containment leakage rate was calculated using the " Absolute Method" en a "Tetal Time" basis as described in American National Standard N45.4 - 1972. In accordance with 10CFR 50; e.ppendix 'J ' the accuracy of the Type 'A' leak test was verified by the performance of a Supplemental Test. The Supplemental Test was conducted for eight (8) hours while a metered leakage cf 2 77 SCFM (C.1779 % wt./24 hrs equivalent; was imposed on the containment. Thus, Item 'B' of the Leakage Rate Summary represents the composite leakage measured for the containment, that is, containment leakage plus the ~ imposed leak. When the known value of the imposed leak is deducted.fren the measured composite leak the resultant is the contain-ment leak rate L'AM =easured during the Supplemental Test. _y_ C i

32 Discussicn of Type 'n' Tes: Results (Cont'd) This is represented as Ite 'D' on the Leakage Rate Summary. The results of the Supplemental Test, that is, the correlation between ILRT Type 'A' leak rate (LAM) and the resultant containment leak rate (L'AM) is indicated as Item 'E' on the Leakage Rate Summary. Here the difference between the contain=ent leak rate measured during the Type '4' test and during the Supplemental Test is shcwn to be -C.0061 % vt./24 hrs. As stated in Section 2.0 "ILRT Acceptance Criteria", the maxitum allouable difference between these ceasurements shall be within = 0.25 L which is equivalent tc = 0.0625 % wt./24 hrs. a As can be seen frem the Leakage Rate Su=rary, excellen: correlation has been achieved. 33 Discussion of Type 'c' Leak Rate Penalty Frior to the performance of the Unit 2 Pre-Operational ILRT, the ::RC imposed a prerequisite that required the draining and venting of additional systems or per: ions of systems not specified in the test procedure. In the event this could not be implemented, the results of the isolation valve local (Type 'O') leak tests fcr these ~ systets eculd have to be added to the ceasured contain-cent (Type 'n') leak rate. i A review of the affected services revealed'that it uas not practical, due to the existing piping configurations. -5

33 Discussion of Type ' ' Leak Rate Fenalty (Cont'd, to ec= ply with this prerequisite for all cases. '.lhere possible, the test procedure was revised to implenent the aferementioned prerequisite. For the remaining services, the associated containment isclation valve local leak rate test data was taken from Fre-Operational Test Procedure 2 PO-C33-332. As a result of the measurements made during the local valve leak rate tests, the total Type 'C' leak rate penalty was calculated te be -C.C294 is w:./2L hrs. Thus, the total reper:atie containment leak rate is increased to (-C.CC425) + (-0.0294) er -0.03365.fe' wt./ 24 hrs. (0.14 L ) which is-still well below the acceptance C criteria of -0.1575 5 wt./2L hrs. (C.75 L_}. a O P 4 4 4.0 COI: DUCT OF TEST 4.1 Organica icn cf Test The D. C.

This was a visual inspection intended to uncover any evidence of deterioration or systen de-ficiencies that would violate the integrity of the containment pressure boundary. The inspection did not uncover any adverse conditions. Therefore, after having verified the co=pletion of the valve line-up and all of the c her test prerequisites and initial conditions, containment pressurization was initiated. Fressurizaticn of the Unit 2 reae:cr centainmen; began at 0114 hours on Septe=ber 30, 1977 Data ecllection for this period consisted of an hourly log of containment average temperatures, pressures, vapor pressures, and ~ ambient temperature and pressure. .it 1200 en Septenber 30, a pressure cf 12 5 FSIG was-achieved and pressuriza-tion was terminated. This tarked the beginning of the stabilizatien period. O

4.2 Log of Times and Events (Cont'd) All test parameters were recorded in half hour intervals for a preliminary determination of the containment leak rate and the establishment of stability criteria. The stabilization period was terminated at 0600 on October 1, when stability criteria had been demonstrated. The pressurization spool piece was removed, a blank flange installed and bubble tested for leak tightness. The Integrated Leak Rate Test data collection began at 0600 on October 1. Data was collected in half hour intervals fer 31.5 hours, 7 5 hours in excess of the 24 hour requirement. At 133C. October 2, the test peried was declared over and a leakage of 2 77 scfm was established as the " imposed leakage" for the Supplemental Test period. The " imposed leakage" was allowed to stabili:e for a half hour and data collection for the supplemental Test began at 14C0 en October 2. The test data was collected in half hour intervals for 6 hours, 2 hours in excess of the 6 hour requirement. The test was declared complete at 2200 on October 2. The containment was subsequently depressurized and systems were restored to normal as required by plant Operations. During the performance of ILRT. repeated proble=s with the en-site method of processing ra.: data proved to be a

i l 4.2 Log of Times and Ever.:s (Cont'd) too overwhelming, due to the large volume of data, to calculate up to the minute leakage rates.

Ecreover, because of the ever increasing back1cg of data, the continued use of the on-site programmable calculators was eventually abandoned.

The collection of data continued, however, based upon the trend of leak rate calculations performed early in the test which indicated a leak-tight containment. Thus, the final hcurs of data collection for the Type 'a' Test and all eight hours f.or the Supplemental Test were conducted without the benefit of on-site knowledge Of the final measured leakage rate. It was for these reasons that the Type 'A' Tes and Supplemental Test were extended beycnd the original twenty-four hour and six hour test periods, respectively, to provide additional data for subsequen analysis. Upon termination of the Supplemental Test, a second attempt was made :: present on-site leakage rate calcu-lations to the :30 inspector fcr his review. In place of the programmable calculators, the original ec=puter programs used for the Unit 1 Pre-Operational Il3T vere accessed free the American Electric Power Service Corpcration's cc=puter disc s:Orage. .4 cc puter punch card deck was assembled frc: the Uni 2 Il?.T data and transmitted to the I!ew York computer facility via micro-wave.

50 TEST INSTRU?EI:TATIOE AI'D E.UTF"T 51 Test Instrumentation Specifica:icns The best state of the art pressure, temperature, and vapor pressure instrumentation was employed during the ILRT test. The ice condenser reactor containment is unique ~in the fact that containment design pressure is limited to 12 PSIG. This low pressure requires more accurate instrumentation to detect leakage to the same degree as for conventional containments with design pressures of 50-60 PSIG. Six precision Menscr Quartz'Mancmeters were used to measure containment absolute pressure. Two sensed 1cwer volume pressure, two upper volume, and two ice condenser pressure. A seventh Manometer measured ambient pressure i during the test. Each instrument was supplied with an 1 j UBS certified standard calibraticn ccrrection chart. These instrument corrections were pre programmed into 1 I the leak rate computer program to allow direct input cf i the manometer readings. When the aforementioned instrumen corrections are applied the manometer accuracy is specified as

• 0.01% full scale _with manometer resolution specified as C.0001 PSIA.

The three containment ecmpartments were instrumented with a total of forty-six (46) precisien RTD sensors. The number of. sensors for the Upper,' Lower and Ice Condenser. ccmpartments was sixteen (16), twenty-three (23) and..

e 1 5.1 Test Instrumentation Specifications (Cont'd) seven (7) respectively. Unlike the Unit 1 Fre-Operational ILRT, platinum RTD's with stainless steel probe bodies were selected. The sensors temperature coefficient was specified as 0.00385 ohms / ohm /*C with a resistance of 100J3. = 0.2% at 0*C. The 100.CL platinum RTD's were found to be much more durable and as accurate as the 2330 J2. copper sensers used during the Unit 1 ILRT. Each~ platinum sensor was calibrated with a linearized bridge amplifier as a matched set. Both the sensor and its associated bridge amplifier carried the same serial number so that matched' calibration would be maintained. .411 RTD sensor / bridge calibrations are certified traceable to NES. The 0-50 mV bridge output was connected.to a digital printout device pregra=med to accept a linear 0-50 mV output fer i an output of 0-100 F. Overall temperature monitoring system accuracy is =.0.C78oF. Four Cambridge Dew Point Hydrometers were used to sense containment humidity during'the. test. Two units sensed-l lower volume dew point, one Ice Condenser and one in the i upper volume. Each unit is complete with its own samtle pump which draws the. sample through the tirror surface sensor. The sensor is. cooled until vapor is formed en1 1 .the mirrer surface ~and electronic circuitry is used to. maintain an equilibrium conditien on the sensor..The l

3.1 Test Instrumentaticn Specifications (Cont'd) sensor temperature is measured by the use of a platinu= RTD. Each RTD had certification te I;BS. The overall des: point temperature sensing accuracy is =.5'F. A rotameter was used during the Supplemental Test to measure and maintain a constant flow rate for the imposed leak. The rotameter has a calibrated range of 0 56 to 5.86 SCFM air at one atmosphere and 70*F and an accuracy of = 1.0% of full scale. J.s all test instrumentation associated with the leak rate test, the 'otameter has its calibration traceab1'e to I!.S.S. s i s-The chart shown in Table 5 1.1 lists the specifications of test instrumentation used during the test in tatqlar form.

The spool piece was removed after stabilization of the containment had be achieved. A blank flange was installed and leak tested to prevent out leakage from the penetration.

' ~ 6.0 CONTAINMENT MODEL' AfiD LEAK R ATE CALCULATIONS 6.1 Discussion of Containment Free Volume The reactor containment is designed to insure that acceptable limits for leakage to the environment of radioactive materials are not exceeded under conditions resulting from the Design Basis Accident for doses dictated by the 10CFR 100 criteria. The steel-lined, reinforced concrete containment structure, including foundations, access hatches, Ond penetrations is designed and constructed to maintain full containment integrity when subjected to' accident forces. The containment design pressure is twelve (12) PSIG. The reactor containment is divided into three compart-ments; a lower compartment which houses the reactor and Reactor Coolant System, an intermediate compartment housing the energy absorbing ice bed and an upper compartment which accommodates the air displaced from the other two volumes during the unlikely event of a loss-of-coolant accident. A detailed tabularization of the individual free volumes which comprise the three containment compartments is listed on Table Q.P.1-1 of the D. C. Cook Nuclear Plant FSAR. The free volume study was originally compiled in response to Question Q.P.-l concerning the input para-meters used in the ECCS evaluation model and may be found in FSAR Appendix 'P ' ( Amendment 60). o

6.1 Discussion of Containment Free Volume (Cont'd) The following is a summary of FSaR Table Q.F.1-1 on a compartmental basis: TABLE 6.1.1 COMPARTMENT FREE VOLUME (FT.3) Upper Volume 734,829 Lower Volume 365,614 Ice Condenser 163,713 Total Free Volume 1,264,156 As was previously mentioned, the free volume study was originated for ECCS model evaluation and therefore, while the total free volume figure is correct, the compartment breakdown does not reflect the true contain-ment configuration during the Integrated Leak Rate Test. Structural barriers within the containment result in a normal operating containment configuration with the following free volume distribution: TABLE 6.1.2 COMPARTMENT FRER VOLUME (FT.3) Upper Volume 687,819 Lower Volume 365,614 Ice Condenser 210,723 Total Free Volume 1,264,156 l 'Th'e differences between Table 6.1.1 and Table 6.1.2 lie l i

6.1 Discussion of Containment Free Volume in the fact that in Table 6.1.1 the upper volume includes the free volume (47,010 Ft.3) of the ice condenser upper plenum which, under normal circumstances, is physically separated from the upper volume. It is also important to note at this time that the ice condenser free volume i 4 in both Table 6.1.1 and Table 6.1.2 include the free volume that would normally be displaced after ice basket loading. Thus, to obtain the actual free volume for this compartment the volume of ice resident in the ice baskets must be deducted. Prior to the performance of the Unit 2 Pre-Operational ILRT, ice basket weighing data was collected from which the average weight per basket and the total volume of ice was calculated. These values were found to be 1481 lbs./ basket and 51,412 Ft.3 total ice volume based upon an ice density of 56 lbs./Ft.3, During the performance of the Unit 2 Pre-Operational ILRT, i the missile shield normally located directly above the i reactor cavity was removed. The reactor cavity, which is identified as Volume XIV in FSAR Table Q.P.1-1, has a free volume of 16,lL7 Ft.3 and is normally associated as part' 6f the lower' volume. With the missile shield removed, however, direct communication with the upper volume is established. ~1. When Table 6.1.2 is adjusted to reflect the reduction-in O

~ 6.1 Discussion of Containment Free Volume (Cont'd) ice condenser free volume due to the displacement of ice and the re-distribution of Volume No. XIV, the following free volume distribution thus represents the actual ILRT values: TABLE 6.1.3 COMPARTMENT FREE VOLUME (FT.3) Upper Volume 703,966 Lower Volume 349,467 Ice Condenser 159,311 Total Free Volume 1,212,744 6.2 Volume Weighting Factors Volume weighting factors (VWF) are used in the compart-mental calculation of the containment air fraction. The definition of a volume weighting factor is the ratio of the free volume for a given containment compartment, ie, Upper Volume, Lower Volume or Ice Condenser, with respect to a " Base Volume". For purposes of the Unit 2 Pre-Operational ILRT the Lower Volume was selected as the " base volume".

Thus, for the containment free volume distribution of Table

~~ 6.1 3 the free volume ratio for each containment compart-ment using the Lower Volume as a " base volume" results in the following volume weighting factors: 1 -

6.2 Volume Weighting Factors (Cont'd) TABLE 6.2.1 CONTAINET COMpARTIE!!T VWF Upper Volume 2.0144 't Lower Volume 1.0000 Ice Condenser O.4559 A discussion of how the volume weighting factors (VWF) are applied in the leak rate calculations is presented in Section 6.4 of this report. 63 Temperature sensor (RTD) Weighting Factors A parameter of importance concerning the determination of containment leak rate is the containment air tempera-ture. Assuming an isovolumic relation exists within the containment pressure boundary, by definition of the perfect gas law the pressure of a gas varies directly with temperature. Therefore, it is necessary to f temperature compensate the pressure measurement (s) made 1 i for each compartment with its associated average air temperature. Due to large free volumes of air' under consideration, it would require an infinite number of-sensors per compart-8 ment to determine the average air temperature by the simple arithmetic average of all associated measurements. Being a finite number of sensors must be used, a i' weighted average" is computed for each of the three S - O

~ l 63 Temperature Sensor (RTD) Weighting Factors (Cont'd) containment compartments. The weighted average temperature for each compartment is i computed by summing the products of sensor reading and its associated temperature sensor (RTD) weighting factor for all sensors located in that particular containment compar tment. This may be expressed mathematically by: 1=n ][3 K T Tavg. = 1 1 i=1 Uhere: T = the measured temperature 4 for sensor 1. the associated sensor K1 = weighting factor. The temperature sensor (RTD) weighting factors are derived by a volumetric analysis of each compartment to determine each sensor's " representative volume". Representative volumes are constructed by imaginary and/or physical boundaries separating the various temperature sensors within a particular containment compar tment. The volume contained within these boundaries is calculated using approved scale drawings for the ~ D. C. Cook Nuclear Plant. Once all the representative volumes have been determined, the individual temperature '? sensor (RTD) weighting factors are computed on a compartmental basis using the formula: i. O

63 Temperature Bensor (RTD) Weighting Factors (Cont'd) Representative Volume (Ft.3) Weighting Factor = 1[3RepresentativeVolumes(Ft.3) The total of all temperature sensor (RTD) weighting factors for each containment compartment is equal to one. 6.4 Containment Leak Rate Equations As indicated earlier in this report, the American National Standard - ANSI N45 4 - 1972; Leakage Rate Testing of Containment Structures for Nuclear Reactors was used as a guideline for leak rate calculations. The following is the deriviation of the equations used in the calculation of containment leak rate. From the ideal gas law: IY N RT, and PV = W RT o 1 1 1 o I Where: P = total absolute pressure in containment o at the first test interval. 4 total absolute pressure in containment P1 = at the end of test interval 1. i T = weighted average absolute temperature at start of test (*F + 459 7). ~ T1 = weighted average absolute temperature at the end of the test interval 1. V = internal volume of containment assumed to remain constant. W = original weight of air in containment at first test interval. 9

6.4 Containment Leak Rate Equations (Cont'd)

Where, VP

= vater vapor pressure at the g start of the test. VP1 = vater vapor pressure at the end of test interval 1. Thus, equation 6.4.1 may be used to compute the normalized weight of air within a containment, of total volume V, at the end of any time interval (1) during the test, Due to the physical separations between containment compartments and the distinct differences in their associated environmental conditions, inherent in an ice condenser containment, the calculation for the normalized weight of air is best determined on a compartmental basis. Thus it is assumed the total mass of air in the entire containment is equal to the sum of the individual air masses for the three containment compartments. On this basis equation 6.4.1 is revised as, (VWF ( E ) VWF ( T ) + VWF ( T -) + T Ui t1 71 y = n VWF ( @ ) VUF (E) VWF ( T ) + + T Uo Lo 70 Eauntion 6.4.2 1. . o.

6.4 Containment Leak Rate Equations (Cont'd) Where: VWF = Volume Weighting Factor U = In subscript indicates Upper Volume parameters. L = In subscript indicates Lower Volume t parameters. I = In subscript indicates Ice Condenser parameters. 0 = In subscript indicates parameters at start of test. 1 i = In subscript indicates parameters at end of test interval 1. As can be seen above, equation 6.4.2 is actually the normalized weight equation 6.4.1 calculated three times, once for each containment ecmpartment. The fractional amount of air for the three compartments are proportion-ately combined by the volume weighting factors (VUF) which are computed as described in Section 6.2 of this report. i 65 Statistical Treatment of Data The resulting values of the normalized weight of air W, calculated as described in Section 6.4 of this report, n are plotted on a graph whose axis are W versus time. A n least-squares analysis of the resulting graph-yields a ~' straight line. The slope of the regression line represents the change in .the normalized weight of air per unit of time, thus it is the fractional leakage per hour. This is converted to - 3 5-

Treatment of Data (Cont'd) ~ From the above prerequisite calculations, the confidence limits on leakage rate (slope b) are expressed as B = KS, where the value of 'K' is dependent upon the b desired level of significance and the appropriate number of degrees of freedom. The value of 'K' is taken from Table 6 5 1 of this report showing the distribution of 'K' with respect to the level of significance and the [ number of degrees of freedom. The level of significance (et) is the term used to describe degree of possible error associated with all points on the regression line. For a ninety-five (95) per cent confidence level the level of significance is i five (5) per cent. Thus, those values of 'K' listed g under a level of significance (e() of 0.05 are applicable, depending upon the existing degree of freedom. l Two constraints determine the regression line; the centroidal point (t, E ) and either the slope (b) or n intercept (a). Therefore, if n is the number of readings for W, the number of degrees of freedom (9 ) is given by, n i) = n - 2 During the ILRT, readings are taken at time intervals of one half hour with time t equal to zero for the first reading.

Kennedy was used as a reference for the statistical analysis. 6.6 Discussion of Computer Program The computer calculations performed for the containment leak rate analysis is implemented by two separate programs. The first program creates a data file from which the second program for linear regression and confidence I limits draws its information. The data file is established by first constructing a deck of computer punch cards containing the run number, elapsed time, and the corresponding temperatures, pressures and dew l points as recorded at the end of each time interval during the test. All calculations and printout formats 4 for each of the measured parameters are executed on a compartmental basis. The data file program takes the millivolt values ~~ representing air temperature and, from the instrument calibration data, converts them to the corresponding *? temperature. Each *F air temperature is then multiplied f by its corresponding RTD weighting factor and summed to g _

6.6 Discussion of Computer Program (Cont'd) provide the weighted average temperature in

• F.

To express the weighted average temperature in absolute units, 459 7 is added. Finally the data file program prints out the individual millivolt input values, the corresponding unweighted temperatures and a " Summary of Weighted Average Temperatures" expressed in both 'F and *R. The data file program determines the dew point, and hence vapor pressure, by taking the hygrometer millivolt output and, from the instrument calibration data, converts this initially to dew point expressed in 'F. The re-sulting dew point is then converted to vapor pressure (PSIA) based on the Goff-Gratch formulas for saturation vapor pressure over water or over ice. The data file program prints out the individual millivolt input values, l* the corresponding dew point, resultant vapor pressure and summarizes these parameters for each compartment. The portion of the data file program dedicated to con-tainment pressure reads a total of seven input values of uncorrected absolute pressure, two per containment compartment and one for the prevailing ambient condition. The program corrects che input values from instrument ca7,1bration data and averages the two associated pressures for each compartment. An average of all three containnent . compartments is taken thus representing the mean contain-ment absolute pressure. The ambient reading is subtracted 9 -r-

6.6 Discussion of Computer Frogram (Cont'd) from the mean containment absolute pressure to yield the mean containment gage pressure. The program then prints each uncorrected and corrected pressure as well as a " Summary of Corrected Average Pressures". The establishment of a data file serves several useful functions. As mentioned before, its primary function is to provide weighted and/or corrected information to the linear regression and confidence limits program for ultimate leak rate computations. As can be seen in the accompanying Table 6.6.1 it also provides a comprehensive and highly organized hard copy of measured parameters for documentation purposes, from which test personnel may easily perform aninput error check of the data.

Moreover, through the convenience of the parameter summaries, on the spot confirmatory calculations may be easily per-i*

formed by the site NRC Inspector as well as the test supervisor. Once the data file is complete and verified to be free ~ of input error, the second program for linear regression and confidence limits is executed. The program calculates the amount of air in each compartment, using the equations presented in Section 6.4 of this report, as based on the original amount of air ';in each compartment at the start of the test 4 + O

6.6 Discussion of Computer Program (Cont'd) (Computer Run #1). The fractional amounts of air in each compartment are then combined to yield the fractional amount of air for the entire reactor contain-ment. The program computes the leak rate at a given time from input values of pressure, temperature and vapor pressure stored in the data file. The leak rate, on a per cent per 24 hour basis, is determined by the least-squares method a: described in Section 6 5 of this report. i j The program is designed to allou evaluation of test results every half hour after the first 3 sets of data. A print out for all sets of data up to and including the data just submitted is provided in the form of a tabulated i summary. Included are fractional air reports for each compartment, for the containment as a whole, as well as the 24 hour leak rate at the time the last set of data i was taken. In addition, the upper and lower leakage bounds associated with the 95% confidence limits are printed out. Reproductions of the aforementioned tabulated summary for the Integrated Leak Rate Test and Supplemental Test may i be found in Section 8.0 of this report. Y ~. '.. '

~ 70 ANALYSIS AND INTERPRET!, TION The previous sections of this report described the method of measuring and compucing the containment leakage rate. This section will be dedicated to a discussion of the observations and conclu-sions drawn from the performance and subsequent analysis of this containment ILRT. Also included in this section is a presentation on the error analysis related to the test instrumentation. 71 Discussion of Graphical Test Data Figures 7 1.1 and 7 1.2 are the graphical representations of the Integrated Leak Rate Test and Supolemental Test data respectively. The axis of these graphs are the normalized weight of original air versus time. The slope of the regression line is the leakage rate. Examination of Figure 7 1.1 reveals the dispersion of data points, representing the normalized weight (W ) I n containment air, results in exceptionally horizontal regression line. A regression line of this nature over the indicated 31 5 hour test period is indicative of an extremely leak-tight containment which is confirmed in the fact that the average change in W Per tui

• time, n

hence leak rate, is -0.00428 %/24 hrs. when expressed on a daily basis. The dispersion of data points yields a variance (mean square deviation) in the leak rate of = 0.00422 % wt./24 hrs. The variance is computed on a 95% confidence level which results in a lower leakage li'it of -0.008'50 % wt./24 hrs. The 95% confidence level m 4

71 Discussion of Graphical Test Data (Cont'd) lower limit is still well within the specified allowable leak rate of -0.1875 % wt./24 hrs. The graphical representation of the Supplemental Test may be found on Figure 71.2 of this report. As illustrated, with the supplemental leak rate imposed on the contain-ment, the change in the normalized weight (W ) I n containment air per unit time is much more pronounced than in Figure 7 1.1 as would be expected. It is interesting to note, however, that because the measured containment leak rate was extremely low, the change in W Per unit time as shown for the Supplemental Test is n only 1 5 per cent greater than the Technical Specification limit for containment leak rate and, thus, may be viewed as a dramatic comparison with the measured containment 1eak rate shown in Figure 7 1.1 For ease of comparison the portion of the regression line from run 1 to 17 of Figure 7 1.1 has been superimposed on Figure 7 1.2. Figure 713 is a plot of the average absolute pressure (PSIA) for each containment compartment. As indicated, each containment compartment generally exhibits the same steady decay in pressure during the 31 5 hours of the ILRT. A calculation on-the measured change in the average absolute pressure over runs,1 to 64 for the Upper, Lower and Ice Condenser Compartments results in A' & P of 0.08'68, 0.0887 and 0.0870 PSI respectively O e.- - - w,

71 Discussion of Graphical Test Data (Cont'd) with an overall average change in absolute pressure of 0.0875 PSI. When the standard deviation is computed for the average absolute pressure measurements tre standard error is found to be

• O.00085 PSI.

As can be seen in Section 7 3, the ILRT instrument error analysis uses the very conservative value for standard error of

• O.003 PSI.

Figure 7 1.4 is the graphical representation of the average vapor pressure (PSIA) for each containment com-partment as measured during the ILRT. This graph clearly 3 demonstrates the contrasting environmental conditions 4 experienced in the three containment compartments. As shown on Figure 7 1.4 the Upper and Ice Condenser com-partments demonstrate relatively stable moisture content s throughout the test while the Lower compartment experiences an appreciable " drying out". The steady decrease in the ~ partial pressure of the water vapor present in the Lower compartment air is probably brought on by a migration of relatively colder drier air from.the Ice Condenser com-i partment which, in turn,' promotes condensation therein. i The weighted average temperatures for.the three contain-ment compartments have been plotted on the graph of "*-ure 7 1.5 The Lower and Upper containment volumes exhibit -about the same steady decreasing trend in temperature. ' 1.~ Both compartments experienced sul approximate 15 *F drop i -l E. ..._,.....s

^ l i 71 Discussion of Graphical Test Data-(Cont'd) in temperature over the 31 5 hours or 0.05 *F/hr.

Thus, it may be concluded from this observation that the Upper and Lower containment compartments will stabilize in temperature and tend to maintain their stability through-out the coarse of the leak rate test.

The plot of Ice Condenser compartment average temperature, however, illustrates that stabilization here is quite another matter. While the overall change in temperature from Run 1 to Run 64 is an increase of only 0.68 *F for the 31 5 hours, much larger *F/hr. changes are experienced because, unlike the Upper and Lower compartments, the trend is not constant but rather tends to cycle. The cyclical variations in Ice Condenser average temperature, whose magnitude is typically 0.06 *F/hr. and as much as 0.23 *F/hr. are caused by the periodic defrosting of the Ice Condenser air handler cooling coils. This was also a problem on the Unit 1 Pre-Operational ILRT and steps were taken during this test to minimize this affect by manually actuating defrost on selected air handlers. While the defrost affect *on average temperature was somewhat reduced by this effort, compared to the Unit 1 " I test, its affect on temperature stability makes compliance with the 0.1 *F/hr. stabilization criteria impracticable. A revised stabilization criteria for the' Ice Condenser Spmpartment is,under consideration for use in future i containment perodic re-tests. t

1 53 Pressurization Apparatus The Plant air system was used to pressurize the contain-ment for the Integrated Leakage Rate Test. A three state centrifugal air compressor located in the turbine room supplies compressed air to the plant air system. ~ The compressor is designed to provide 1500 cfm of oil free compressed air at a discharge pressure of 100 PSIG-continuously. Air discharged from the plant air compressor retains the third stage heat of compression. An after-I cooler installed in the discharge line, is designed to cool the air to within 10 F of its inlet cooling water temperature. The condensed moisture resulting from the j cooling is removed by a cyclone-type separator installed immediately downstream of the aftercooler. The air discharged from the moisture separator is fsd through the plant air system to the containment test pressurization filters and dryers. In order to avoid condensing water vapor during the test the plant air supplied is dried' l to a dew point that is below the coldest temperature anticipated in the ice condenser. Two parallel, 100 percent capacity strings of prefilters prevent contam-ination of the drying dessicants from mositure carryover i or scale. Two afterfilters in parallel protect the containment from dessicant dusting. J The dried and filtered air is fed through a three inch test line, spool piece, and valve to penetration #CPN-57 l This valve was used to throttle' the air flow during pressurization and depressurization. ~ {

72 Discussion of Parametric Study A parametric study was performed using the test data collected during the Unit 2 Pre-Operational ILRT to determine the affect varying the volume of ice resident in the Ice Condenser compartment would have on the leak rate calculations. Ihe parametric study was comprised of three conditions of ice basket loading, i.e., Case I maximum ice load, Case II minimum ice load allowed by current Technical Specification and Case III actual ice load. In the case of maximum ice load, the entire internal volume of each ice basket was assumed to be occupied by ice. The ice volumes for the actual and Technical Specification lower limit were calculated based on 1481 and 1220 lbs. per basket respectively. By varying the volume of ice in the Ice Condenser the associated net free volume is so affected. The resultant Ice Condenser free volume for the three cases is reflected accordingly in the Volume Weighting Factors (VWF) used in the calculation of normalized weight of containment air. A detailed discussion on VWF is presented in Section 6.2 of this report. The results of the parametric study has been tabularized

• Leak Rate expressed in % wt./24 hrs.; - denotes out leakage.

Using the actual weight of ice as a basis for comparison Table 7.2.2 illustrates the change in the calculated leak rate: TABLE 7.2.2 Comparison Containment ILRT Supplemental Test Actual With: 4 vt./2k hrs.* T $k 4 wt./24 hrs.* C $k Maximum Ice +0.00698 163 1 +0.00829 4.36 Minimum Ice -0.00280 65.4 -0.00336 1 77

• - Denotes increase in out leakage.

A review of the above Table 7 2.2 indicates the affect of varying the ice volume between the extreme condittons of maximu= and minimum ice load conditions is not as significant, in tergs of per cent difference in the overall leak rate, lo

72 Discussion of Farametric Study (cont'd) when the magnitude of leakage closely brackets the ILRT allowable limit of -0.1875 % wt./24 hrs. as it is for relatively smaller leak rates. In the Supplemental Test, where the magnitude of leakage is approximately equal to the ILRT allowable limi t, the difference in the leak rate between the actual leakage and the maximum and minimum ice load leak rates is 4.36 and 1 77 per cent respectively. The overall change in the leak rate for the two extreme ice load conditions is equal to 0.01165 % wt./24 hrs. or 6.2 per cent of the allowable leak rate. Leakage of this magnitude would be significant in the event the acceptance of an ILRT was a borderline case. When the leak rate is small, as shown in Table 7 2.2 for the ILRT results, the affect on the magnitude of the measured leak rate is dramatic. There is, however, little significance at these levels of leakage, in that, even with a 65 per cent increase over the actual leak rate the resultant leakage (-0.00708 % wt./24 hrs.) is still only 3 8 per cent of the ILRT allowable. I It is interesting to note at this time that the difference ~ between the maximum and minimum ice load conditions represents an ice volume of 30,936. cubic feet or 6 1-i?3 x 10 pounds of ice. To incur the 6.2 per cent 8 ! l

72 Discussion of Parametric Study (Cont'd) error in the measured leak rate, as discussed above, due to inaccuracies in the ice basket weighing would require an error in measurement of approximately 890 pounds of ice per basket. The present method of weighing a representative sample of ice baskets and computing the statistical average weight per basket produced a standard deviation of only 35.45 pounds for the measurements taken prior to this ILRT. Thus it may be concluded from the above results, that the i variation in the calculated leak rate, as affected by the extreme conditions of maximum or minimum ice volume is small but would be significant in the acceptance of borderline ILRT's. It may also be concluded that the uncertainties involved in determining the quantity of ice within the ice baskets, and hence the net free volume of the Ice Condenser compartment, are well within the limits of required accuracy. 73 Instrument Error Analysis The following calculation represents the instrument error analysis performed to substantiate the selection of.the test instrumentation utilized to provide input to the j computation of the containment leakage rate.

73 Instrument Error Analysis (Cont'd) may contribute an error of = 0.076 L, to the calculated containment leakage rate. This level of inaccuracy is more than tolerable in as much as the containment allow-able leakage rate L, is reduced for purposes of contain-ment integrated leakage rate testing to a value of 0 75 L,. Moreover, the required correlation between the ILRT and Supplemental Leak Test is established at = 0.25.L,. b OE T- - 6

1 90 LCCAL LEAK TEST PROGRAM A local leak test program was conducted in accordance with guide-lines specified in 10CFR 50 Appendix'J', FSAR, and Technical Specifications, under AEPSC written and I&M approved procedures, 2 PO-033-330 " Containment Penetration and Personnel Lock (Type 'B') Leak Test" and 2 PO-033-332 " containment Isolation valve (Type 'c') Leak Test". These tests were conducted as a prerequisite to the Integrated Leak Rate Test to systematically verify acceptable leakage across each containment penetration and pressure containing boundary. The program consisted of Type 'B' tests designed to determine leakage through the containment penetrations, air lock door seals, lock cover flange seal, ring body flange seal and overall air lock leakage, as well as Type 'C' tests designed to determine leakage across isolation valves. The leakage detection instrumentation used in the conduct of the Type 'B' and 'O' tests were calibrated prior to the tests and are certified traceable to NBS. These instruments (Volumetrics Leak Rate Monitor) are self contained mass flow leak test systems capable of measuring small gaseous leak rates. The monitor pressurized the test volume to a predetermined setpoint (12.0 PSIG). After test pressure is attained precise pressure regulators, internal to the instrument, maintain the pressure setpoint by adding air through a thermal flow sensor. Since the test volume pressure remains constant during the test the amount of air leakage is equal to the amount of air added. This leak rate is electronically converted and displayed on.'a digital rate meter. p -104-t

The origin of this leak was traced to containment penetrations CPN-6 and CPN-51. Examination of these penetrations revealed the expansion bellows, located outside the containment, were cracked in each case. Upon repair, both containment penetrations were re-tested by the local Type 'B' test method and found to have zero leakage. It should be noted that, while repair and re-test of the damaged expansion bellows was performed after performance of the containment ILRT, no action was taken to isolate the affected pene-trations from the containment ILRT-test pressure. Moreover, it is a prerequisite of the ILRT procedure to vent to containment atco-sphere all interval zones of the containment weld channel system. Table 9.4.1 is provided for an individual accounting of the containment isolation valve leak zates reported as total leakage in ~~ Item 9.4 above. In this table each valve is identified by tag number, valve diameter, allowable leakage and actual leakage as measured during the pre-operation leak test. The individual allowable 5eakage values were determined by allocating a p^ortion of t - 106- ) i

~ 90 local isAK TEST FRocRAM (cent'd; the total allowable leakage based on valve size (diameter). The allowable leakage values were determined as a guideline to enable the test engineer to decide which valves should be repaired, if necessary, to meet the total allowable leakage value of 48,827 SCCM (0.443 L ). Referring to Table 9.4.1 it can be seen that for some instances the " actual leakage" measured has exceeded its associated guideline " allowable leakage" limit. The local leak rate test, however, was ? considered acceptable because as per 10CFR 50, Appendix 'J', the cembined leakage for all Type 'B' and 'C' tests must be less than the allowable limit of 0.6 L. A review of the test results a f indicates that the total actual leakage measured for both Type 'B' and 'C' leak rate tests was equal to 0.178 L, or only 129 7 per cent ) j of the allowable limit. i. In addition to the valves and penetrations subjected to the Type 'B' and 'C' local leak rate tests as required in 10CFR 50; Appendix 'J', the spray header check valves associated with the Containment Spray System were leak tested in accordance with FSAR Question 022.15 (4). As specified by the NRC, the acceptance criteria for each check valve is such that the water inventory normally resident in the associated spray header shall not leak out within a thirty (30) day period. In response to this requirement, the volume of vater resident.in the spray headers was calculated from isometric drawings and the leak tests performed with the following results: 9 - 107-t +
