SUMMARY

A reactor building containment integrated leak rate test (CILRT) was I conducted at Sequoyah Nuclear Plant (SNP) unit 2 November 20-21, 1984, in conjunction with the cycle 2 outage. The CILRT was concluded in 25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months and 29.5 minutes and included 120 samples.

The initially measured leakage rate was approximately 0.22 percentage of containment air mass per day (% per day) as calculated by the mass leak rate (MLR) method prescribed in ANS 56.8. Thus the initully measured leakage rate exceeded the SNP unit 2 allowable limit of 0.1875 percentage of containment air mass per day (.75 LA )*

I Packing leaks were found on the root valves of two containment pressure sensing lines located on panels 2-L-188 and 2-L-189 and were subsequently repaired. This resulted in a reduction in the measured leakage rate to below the allowable limit.

I Further discussion is included in the test results section of this report (section 7.0) along with a schedule for the future CILRT testing on unit 2.

The final reportable leakage rate was 0.16026 percentage of containment air mass per day as calculated by the mass leak rate I (MLR) method perscribed in ANS 56.8, and the observed 95% upper confidence limit (UCL) was 0.16191% per day. The above mentioned 95% UCL includes leakage measured from Type B&C tests for testable I lines that were in service during the test. The reportable mass lea'c rate was 85% of the allowable 0.1875% per day (0.75 LA )*

2.0 INTRODUCTION

As prescribed in Sequoyah Nuclear Plant (SNP) unit 2 Technical Specification 4.6.1.2, the leakage of air from the boundary forming I the reactor building primary containment is limited to 0.25 percent by weight of the containment air mass per day at a pressure of Pa ,

12.0 psig. In conformance with Title 10, Code of Federal I Regulations, Part 50, Appendix J, Sequoyah Technical Specifications require that a reactor building CILRT be performed as part of the surveillance programs to demonstrate the continuing leak-tight integrity of the reactor building primary containment.

I The first inservice reactor building CILRT was successfully completed on Sequoyah unit 2 by personnel of Tennessee Valley Authority (TVA) on November 21, 1984. This test was conducted in I accordance with a plant approved surveillance instruction, SNP SI-156, which is on file at the plant site. This surveillance I instruction implements the requirements of Sequoyah unit 2 technical specifications and 10 CFR 50, Appendix J. The American National Standard for Containment Testing, ANSI 45.4-1972, the proposed American Nuclear Society for Containment Testing, ANS 56.8, I and the procedure outlined in Becthel's topical report, " Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants" (BN-TOP-1, Revision 1) provided I guidance for the procedure implemented by the surveillance instruction.

Sequoyah unit 2 is a 3,411 megawatts thermal, pressurized-water reactor employing an ice condenser pressure suppression containment.

The Final Safety Analysis Report defines the calculated peak accident pressure, P , to be 12.0 psig. The reactor building containment is divid$d into four major compartments for the CILRT ,

analysis--the lower ice condenser compartment which houses the energy-absorbing ice beds, the upper ice condenser compartment which l encloses the support equipment for the ice condenser system, the 5 lower compartment which contains the reactor and the main piping systems, and the upper compartment which prcvides for a large work area within containment and also can accommodate the displaced air mass from the other compartments in the unlikely event of a loss-of-coolant accident (LOCA). These four compartments are connected by means of blowout panels located between the lower compartment and the lower ice condenser compartment and between the upper and upper ice condenser compartments. In the event of a LOCA, steam flows from the lower compartment through the ice condenser compartments $

sad into upper containment. The upper compartment is sealed from 5 the lower compartment to ensure that any steam released in an accident will be forced through energy-absorbing ice beds. For the g performance of the CILRT, the lower and upper compartments were not g' sealed from each other to promote the free flow of air in containment.

This report outlines the objectives, principal events, special equipment used, and analysis of the test results for the CILRT completed on November 21, 1984 on Sequoyah unit 2.

3.0 TEST PURPOSE AND RESULTS 3.1 Test Purpose The objective of the inservice Containment Integrated Leak l Rate Test was to demonstrate the continuing leak-tight integrity of the unit 2 reactor building containment for l return-to power operation.

For Sequoyah unit 2, the leak-tight integrity is defined in I,l l Technical Specification 4.6.1.2 to be that the leakage of air !

from containment is not to exceed 0.1875 percent per day g1 (0.0078 percent per hour) at peak accident pressure, P,. g 3.2 Test Results The initial pressurization of primary containment to 12.70 psig was completed at 1439 hours0.0167 days 0.4 hours 0.00238 weeks 5.475395e-4 months on November 17, and the I) l pressurization penetration (X-54) was isolated. I The 4-hour stabilization period was satisfactorly completed at 1918 hours0.0222 days 0.533 hours 0.00317 weeks 7.29799e-4 months on the 17th (see table 7), during which the primary g!

containment boundary was tested for previously undetected leakage using a soap solution. No significant leakage was discovered El other than that found during the type B&C testing. The g temperature and pressure data taken during the stabilization gl' period are shown graphically in figures 10 and 11.

The CILRT sampling period began immediately after stabilization was reached at 1918 hours0.0222 days 0.533 hours 0.00317 weeks 7.29799e-4 months on the 17th. The leakage rate was approximately 0.24% per day and showed a slightly upward trend.

Test engineers noticed that the upper-ice compartment was experiencing a significant and steady temperature increase I above its normal operating range of 19 F to a maximum temperature of 28.97*F at 2108 hours0.0244 days 0.586 hours 0.00349 weeks 8.02094e-4 months on the 17th (shown in figure 12). The shift engineer verified that two glycol I recirculation pumps for unit 2 had tripped off, thereby causing the warming trend in this compartment. SNP operators restarted the two glycol recirculation pumps at 0318 hours0.00368 days 0.0883 hours 5.257936e-4 weeks 1.20999e-4 months on the 18th.

This caused the upper-ice compartment temperature to I immediately begin a rapid cooling trend that lasted for approximately 17 hours1.967593e-4 days 0.00472 hours 2.810847e-5 weeks 6.4685e-6 months until the temperature in the upper-ice condenser compartment stabilized within its normal range (see figure 12). The containment leakage rate subsequently followed i this cooling trend with a slightly downward trend to a value of approximately 0.22% per day at 1953 hours0.0226 days 0.543 hours 0.00323 weeks 7.431165e-4 months on November 18, shown I in figure 13. TVA personnel continued efforts to locate previously unidentified leakage that could cause the leakage rate to exceed the allowable limit of 0.1875% per day (0.75 L )* A Some problems were experienced with the mensor quartz manometer gauges used to measure the containment test pressure during the CILRT. One of the two gauges measuring the I pressure in the upper compartment began malfunctioning and was replaced at 2100 hours0.0243 days 0.583 hours 0.00347 weeks 7.9905e-4 months on the 18th. Next, a small leak in a polyflo tubing connection terminating at the two gauges -

measuring the. upper-ice compartment pressure was found and repaired at 0845 hours0.00978 days 0.235 hours 0.0014 weeks 3.215225e-4 months on the 19th. Finally, at 0755 hours0.00874 days 0.21 hours 0.00125 weeks 2.872775e-4 months on the 20th, another gauge monitoring the pressure in the upper compartment malfunctioned and was disconnected from the I pressure sensing line leaving a single quartz manometer to measure pressure in this compartment.

I The Reactor Coolant System (RCS) Pressurizer water level was continuously monitored by the CILRT data acquisition system throughout the CILRT period so that adjustments could be I accurately made to the containment " free-air" volume calculations. Other component levels in the RCS were monitored via plant instrumentation by plant personnel during the CILRT to account for other " free-air" volume changes not reflected by the pressurizer. With the exception of the RCS, I all other components exposed to CILRT pressure were at 100%

level for the duration of the CILRT and subsequent verification test. Thus, no additional " free-air" volume adjustments were I, necessary. Test engineers requested that operations control the water level in the primary system so that no abrupt level I changes would occur. Earlier on the 18th the RCS pressurizer water level transmitter signal was temporarily lost at two different times because the sensing cable was damaged and in each instance had to be repaired.

TVA personnel made two entries into primary containment on the 20th to search for unidentified leakage paths. The first containment entry was made at 0030 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months , followed by the second entry at 0930 hours0.0108 days 0.258 hours 0.00154 weeks 3.53865e-4 months , with neither entry detecting any significant leakage. 1 Packing leaks were found at 1030 hours0.0119 days 0.286 hours 0.0017 weeks 3.91915e-4 months on the 20th in the unit 2 annulus on root valves of containment pressure sensing l

W lines located on panels 2-L-188 and 2-L-189. The packing was tightened and immediately the leakage rate began to decrease. g The CILRT test period was rebased to sample 67 at 1245 hours0.0144 days 0.346 hours 0.00206 weeks 4.737225e-4 months 3 on the 20th with the leakage rate at approximately 0.1690% per day and following a slightly downward trend.

The CILRT was conducted for 25.49 hours5.671296e-4 days 0.0136 hours 8.101852e-5 weeks 1.86445e-5 months and 120 data samples "

were collected. The leak rate reported by the mass method (MLR) was 0.16026 percentage of containment air mass per day I (0.0067% per hour), and is shown graphically in figure 14. 5 The observed 95 percent upper confidence limit for the measured mass leak rate was 0.16191% per day (0.0067% Per hour). This g.

reportable leak rate represents 85% of the allowed 0.18750 g' percentage of containment air mass per day (0.75L A) as described in Technical Specification 4.6.1.2. The calculated total time leak rate (TTLR) was 0.15692% per day and is shown graphically in figure 15, with a 95 percent upper confidence limit of 0.2207% per day. The higher TTLR confidence limit is due primarily to the different calculation technique used to determine confidence limits in the total time analysis as defined in BN-TOP-1, Revision 1.

After the completion of the CILRT, a supplemental imposed leakage verification test was conducted to check the results of the CILRT. The imposed leakage was measured using a mass g

flow meter technique, utilizing a Hastings Mass Flowmeter. A leakage rate (L ) f 0.9581 L was imposed on the containment E R A building.

The calculated containment mass leak rate (LRM) during the 4.23 hour2.662037e-4 days 0.00639 hours 3.80291e-5 weeks 8.7515e-6 months verification test was 0.36250 percentage of containment air mass per day shown graphically in figure 23. Agreement, g as shown in Appendix B using MLR, between the CILRT and the 3 verification test was achieved and was found to be -0.1546 L which is clearly within the 0.25 L required A

by 10 CFR 50, A Appendix J.

The calculated TTLR dering the 4.23 hour2.662037e-4 days 0.00639 hours 3.80291e-5 weeks 8.7515e-6 months verification test was 0.35692 percentage of containment air mass per day and is l shown graphically in figure 24. Agreement, using TTLR, 4 between CILRT and the verification test was also achieved and was found to be -0.1635 LA*

The leak-tight integrity of Sequoyah Nuclear Plant unit 2 was accurately measured and recorded by computer-based instrumenta-tion. The computer-based data acquisition system provided I reliable, immediate calculations of test data, which allowed test engineers to more easily monitor important test parameters.

I The CILRT and subsequent verification test were completed at 2242 hours0.0259 days 0.623 hours 0.00371 weeks 8.53081e-4 months on November 21, 1984.

4.0 CONDUCT OF TEST I In compliance with Surveillance Instruction SNP SI-157, local leak rate tests were performed on containment closures (hatches and resilient seals), bellows, and electrical penetrations. Local leak rate tests were also performed on valves forming the boundary of the primary containment in accordance with surveillance I instruction SNP SI-158.1. The above mentioned surveillance instructions were performed prior to the CILRT. All valves and penetrations satisfactorily met leakage requirements prior to the performance of the CILRT.

Appendix D shows a complete summary of the LLRT performed on SNP unit 2 since the preoperational CILRT performed in February 1981.

5.0 MEASUREMENTS AND CALIBRATIONS 5.1 Test Equipment Table I lists the range, accuracy, and repeatability of the special test equipment used in the unit 2, cycle 2 CILRT.

Prior to the start of the CILRT, all test equipment was calibrated by the TVA Central Laboratiories or other facilities with standards traceable to the National Bureau of I Standards. After installation of all special test equipment inside containment, each sensor was checked for functional operation. The special test instrumentation interfaces with a portable minicomputer which produces highly accurate remote I scanning of temperature, pressure, and dewpoint sensors.

Upon test completion and depressurization each sensor was again functionally checked to ensure adherence to calibration.

Pressurization for the CILRT was achieved using portable high-capacity air compressors. The compressors were rated at 3,500 SCFM of dry, oil-free air, and brought containment to test pressure in approximately 15 hours1.736111e-4 days 0.00417 hours 2.480159e-5 weeks 5.7075e-6 months , including final

" topping off" stages of presurization.

5.2 Sensor Location Table 2 lists the final volumetric weidhing factor for each temperature and dewpoint sensor based on the 4-compartment model.

Figures 3 through 8 indicate sensor locations. The pressure sensors were divided so that initially two sensors measured

each of the four compartments through penetrations X-27C, X-87D, X-87A, and X-98. Utilizing two pressure sensors per compartment allows the removal of any one malfunctioning pressure gauge during the test and continue to accurately monitor containment pressure. An additional pressure gauge measured barometric pressure at the test station.

5.3 Computer-Based Data Acquisition and Data Reduction The raw test data measured by the special test instrumentation during the Sequoyah Nuclear Plant unit 2 CILRT was scanned and collected by a microprocessor based data acquisition system.

This raw test data was automatically presented to a portable minicomputer system for correction to calibration curves and reduction to containment leak rate. The minicomputer produced 5

immediate statistical and graphical results of the containment test parameters, including temperature, pressure, vapor pressure, mass, and mass leak rate plots.

These calculated results were reported automatically to the '

test director as the data was collected. Figure 2 depicts the functional relationship between the special test instrumentation and the data acquisition and analysis system.

All calculations performed by the minicomputer system were in conformance with the procedures outlined in ANS 56.8, ANSI 45.4 and Bechtel Topical Report (BN-TOP-1, Revision 1).

Source listings for all computer programs are on file with the Division of Nuclear Services, Mechanical Branch, in Chattanooga, Tennessee. Table 3 identifies the principal function of each computer program.

5.4 Reactor Building Containment Model An ice condenser pressure suppression containment presents special problems not normally encountered in the leak testing g of dry containment structures. The pressure suppression 5 design feature requires the reactor building containment to be divided into distinct compartments, where vastly different a temperatures and vapor pressures may exist. While each g compartment is vented to the containment atmosphere during the performance of the CILRT, the direct circulation of air is limited.

Since an ice condenser containment typically exhibita a 40'F temperature differential between the ice compartments and g others, it is necessary to compensate by compartmentalization g so the leak rate is accurately measured. For Sequoyah unit 2 l CILRT, a 4-compartmen;. containment model was used to measure a<

the leak rate. The free air mass is calculated individually g, for each compartment, and containment leak rate is calculated 1 1

from the sum of the compartmental masses. Each sensor within a 1 compartment is volume weighted for the calculation of com-partment average temperature and vapor pressure. Figure 9 depicts the four compartments used in the Sequoyah unit 2 1 reactor building containment model.

6.0 ANALYSIS OF TEST DATA The. previous sections of this report have discussed the general test conduct, calibration methods, and test equipment. In this I section events and problems that influenced the test results are discussed and are used to formulate conclusions on the performance of the Sequoyah unit 2, cycle 2 CILRT.

6.1 Instrument Check The data presented in this section reflects the test results r

i following recalibration and deletion, if necessary, of the special test equipment used during the test.

Two humidity sensors were deleted prior to the start of the l CILRT due to erratic readings. DPE-8, as shown in figure 3, was deleted and its volume weight was set equal to zero, with the volume weights for DPE's 7 and 9 adjusted I accordingly. DPE-10 was also deleted and the vol. wts. for DPE's 11, 12, and 13 were adjusted to account for the loss.

Two temperature sensors, RTD's 19 and 26 were deleted following recalibration of the instruments by TVA's Cent,ral Laboratory. The recalibration indicated that the RTD's were slightly out of tolerance for the 0*F calibration point.

RTD-19, located in the upper-ice compartment, was volume weighted equal to zero, with the volume weights for RTD's 15, 16,17,18, and 20 properly adjusted. RTD-26, located in the I lower compartment, was also volume weighted to zero and the remaining 24 RTD's measurit.g the compartment were adjusted to account for the loss of RTD-26.

One of seven Mensor Quartz Manometer pressure gauges was found to be slightly non-conservatively out of tolerance in the range of pressure used during the CILRT when the gauges were recalibrated following the CILRT. The calibration report provided by TVA's Central Laboratory indicated that the I manometer was producing readings slightly higher than the actual pressure. Test engineers corrected each pressure reading taken by the manometer, which was one of two measuring 3 the lower compartment, during the CILRT and subsequent g

I verification test.

The corrections made to the final CILRT and verification test data did not effect the success of the CILRT performed on unit 2. In addition, all final test results and reported data in this report reflect the above mentioned corrections.

p

I The instrumentation error analysis of Appendix A indicates that the instrumentation used in the unit 2, cycle 2 CIET was accurate to 0.0057 L in determining the containment leak rate A

for unit 2, far surpassing the recommendations of ANS 56.8 g which states that the measuring system be capable of detecting 5 0.25 L g.

6.2 Discussion of Graphical and Tabular Results The November 20-21, 1984, CILRT that was performed on unit 2 at Sequoyah Nuclear Plant was concluded after 120 samples were taken in 25.491 hours0.00568 days 0.136 hours 8.118386e-4 weeks 1.868255e-4 months of testing. Figure 14 is a graphical representation of the liLR and figure 15 is a graphical representation of the TTLR, expressed as a percentage of g containment air mass per day, during the CILRT. Tabulated data 3 accumulated during the CILRT is shown in Table 4.

During the CILRT there were four noticable pressure drops in the lower compartment. The magnitude of the pressure drops was approximately 0.004 psi and were between 4 and 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months apart as shown in figure 16. These pressure drops resulted in corresponding changes to the mass points in the lower compartment at the same intervals (see figure 17). Efforts were made by test engineers both during the test and in the g weeks thereafter to determine the cause of the pressure drops, 5 but no exact reason was discovered.

The temperature trends in the upper-ice compartment were cyclic in nature (see figure 18). The reason for the trends is directly related to the defrost cycles of the ice condenser air handling units. These temperature trends resulted in corresponding mass trends in the upper-ice compartment as h=

shown in figure 19.

Figures 20 through 22 show graphical representations of average temperatures, pressures, and masses during the 25.491 hour0.00568 days 0.136 hours 8.118386e-4 weeks 1.868255e-4 months CILRT. Table 4 is a tabular listing of important g

. measured parameters and corresponding results for the unit 2 5 CILRT.

Final results indicate a MLR of 0.16026 percent per day and a TTLR of 0.15692 percent per day. The associated 95 percent upper confidence limits for the Sequoyah unit 2, cycle 2 CILRT i were 0.16191 percent per day for MLR and 0.22071 percent per l day for TTLR. Wj 1

After instrumentation received post-test calibrations, the g calibration reports indicated that all instrumentation used in 5 the unit 2 CILRT and subsequent verification test was in proper tolerance, with the exception of items already mentioned.

6.3 Discussion of Agreement (Verification Test)

Appendix J to 10 CFR 50 specifies the technique for the calculation of agreement between the CILRT and its subsequent -

verification. Appendix J requires the absolute value of the difference between the measured containment leak rate with a

{ superimposed leak and the sum of the imposed leak and the measured containment leak rate be less than 0.25 L A*

The verification test was concluded at 2242 hours0.0259 days 0.623 hours 0.00371 weeks 8.53081e-4 months on November 21, 1984.

( After collecting 51 samples in approximately 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months , agreement, as prescribed by Appendix J of 10 CFR 50, between the CILRT (Lg) and the imposed leak rate (L,) was reached at

-0.1546 L using MLR, which is well within the 1 0.25 L A A allowable limit.

( Agreement was also reached using TTLR and was found to be

( -0.1635 LA. Appendix B details the methods of agreement calculations.

( Tabulated data collected during the 4 hour4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months verification test is shown in Table 5.

At 0.583 hours0.00675 days 0.162 hours 9.63955e-4 weeks 2.218315e-4 months into the verification test (sample 15), a temperature drop of approximately 0.03*F was experienced in the lower compartment followed by increases of approximately 0.02*F and 0.01*F for samples 16 and 17 as shown in figure 25.

The temperature changes resulted in a corresponding increase of approximately 2.0 lba followed by decreases of approximately 3.0 and 2.0 lhe in the lower compartment (see figure 26).

Similar to the four pressure drops previously discussed that occurred in the lower compartment during the CILRT, a pressure drop of 0.004 psi occured at 3.315 hours0.00365 days 0.0875 hours 5.208333e-4 weeks 1.198575e-4 months into the verification test. The pressure in the compartment increased the following sample by 0.003 psi and then resumed a more normal rate of desent in figure 27. The result was a drop in compartmental

{-, .

mass of approxistely 8.0 lbe'at sample 47._ The lower compartment mass then followed the subsequent pressure increase by increasing approximately 6.0 lbe after which the

-mass-in the compartment normalized.

Figures 23 through 24 shows the mass and total time leak rate hl plots'during the 4 hour4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months verification test,.while Figures 28 through 30 show graphical representations of average temperature and pressure and mass.

7.0 CONCLUSION

S

( The reactor building containment integrated leak rate test l, : performed on Sequoyah Nuclear Plant unit 2, cycle 2 November 20-21, 1984,' recorded a MLR of 0.16026 percentage of containment air mass

{ .

M g

per day, which clearly demonstrates the leaktight integrity of unit 2. The total leak rate of 0.16191 percent per day was less than the allowable 0.1875 percent of containment air mass per day as prescribed under Sequoyah Technical Specifications. .. I The technique of multicompartment modeling coupled with a computer-based data acquisition system yielded immediate results E that accurately measured and displayed the unit 2 containment leak g rate.

The next Sequoyah unit 2 CILRT is scheduled to be performed during the cycle 4 refueling outage approximately 9/87 followed by another after cycle 6. This schedule complies with the normal schedule as outlined in Appendix J to 10 CFR 50 and plant technical specifications.

SUMMARY

ll g

l A. Type B Tests Two methods were used to perform the type B tests - the absolute a method (pressure decay) and the volumetrics mass flowmeter method. 5 Both methods use air or nitrogen as the test medium, with the testable volume pressurized to a designated test pressure. The absolute method determinen the leakage rate by a measured pressure drop during a set time specified in Sequoyah's surveillance instruction, SNP SI-157, for testable penetrations and SNP SI-159 for the personnel air lock test. The Volumetrics mass flowmeter g makes a direct mass flow measurement with readings given in standard g cubic centimeters per minute (SCCM).

All testable penetrations were tested prior to the performance of the CILRT.

Any penetrations or hatch covers opened after the completion of the CILRT will be tested prior to unit startup under the applicable plant-approved surveillance instructions.

A summary of all type B test data since the unit 2 preoperational CILRT conducted in February 1981 is included in this appendix (see Table D-2 and Table D-5).

B. Type C Tests Three methods were used to perform the type C tests--an airflow method, a water displacement method, and the volumetrics mass flowmeter method. The airflow method consists of a rotameter flow facility in line with the testable valve through a test connection. E An air supply is connected to the rotameter facility, which measures 5 the flow of air necessary to replace the air leakage past the valve being tested. From this, a leakage rate is determined.

The water displacement method consists of a calibrated water test tank equipped with a sight glass. A timed water level drop is -

measured to calculate the leakage past the valve (s) being tested. l W

A separate air source is used to ' maintain the water pressure at the prescribed test pressure. A special " water inventory test" is conducted on containment spray, applicable only to valves FCV-72-2 h and FCV-72-39 and the remainder of test utilizing the water displace- 5 ment method are the ERCW discharge isolation valves.

The Volumetrics mass flowmeter is also used to conduct type C tests.

All testable containment isolation valves were tested prior to the performance of the CILRT. The results of these tests are noted in the summary of type C data in this appendix (see Tables D-1 and D-4).

I I

I l I

i Any maintenance action or repairs on containment isolation valves l subject to type C tests which would affect leakage from primary containment will be retested under the applicable plant-approved surveillance instruction before unit startup.

A summary of the data for all type C tests since the unit 2 pre-operational CILRT is included in this appendix. Penetrations in I water-sealed systems subject to inventory restrictions and penetra-tions whose leakage might bypass the shield building emergency gas treatment system are identified in table D-1 and table D-4 of I this appendix.
