pjTRODUCTION The reactor containment building Integrated Leakage Rate, Type A, Test, is performed to demonstrate that leakage through the primary reactor containment and systems and components penetrating primary containment does not exceed the allowable leakage rate specified in the Plant Technical Specifications.

The successful periodic Type A and supplemental verification tests were performed according to the requirements of the E.

I.

Hatch Nuclear Plant, Unit 1 Technical Specifications and 10CFR50, Appendix J.

The Plant Hatch Type A test method is the absolute method des-cribed in ANSI N45.4-1972, " Leakage Rate Testing of Containment Structures for Nuclear Reactors" and ANS N274, " Containment System.

Leakage Testing Requirements", Draft No.

2, Rev. 1 - April 5, 1978.

Leakage rate was calculated using formulas from ANSI N45.4-1972 and BN-TOP-1, Rev. 1. " Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants" (Total. Time) and ANS N274 (Mass-Point) modified for varying contain-ment free air volume during the Type A and verification tests.

The free air volume in calculations was varied to account for changes in reactor vessel water level, and thus changes in free air volume, caused by reactor vessel water temperature changes.

Type A and veri-fication test durations were according to the criteria of BN-TOP-1.

1 The test results are reported in accordance with the requirements of 10CFR50, Appendix J, Section V.B.3 i

II.

TEST SYNOPSIS Containment pressurization was stopped at a containment pressure of 59.5 psig at 1930, 4/6/78.

Thirty minutes later containment pres-sure dropped below 59 psig and was increased to 59.5 psig.

By 2030 the pressure had dropped below 59 psig and was again increased to 59.5 psig.

The pressure again decreased at the same high rate.

An external survey of potential leak paths was initiated due to the repeated high pressure-decrease rate.

Leak survey personnel dis-covered gross leakage through the drywell head flange, but no other significant leakage.

As the drywell head leakage could not be stopped safely with the containment pressurized, the containment was depres-surized to O psig and the head bolts were detensioned.

The drywell head bolts were then retensioned per HNP-1-6705, flange gap measure-monts were taken, and successful local leakage rate test on the dry-well head gasket was performed.

The containment was repressurized and reached test pressure at 1600 on 4/8/78.

During the required stabilization period, two of the four drywell cooler f ans modified to operate during the ILRT tripped and were not restarted.

One half hour into the Type A test, a third drywell cooler fan tripped and was not restarted.

At 0745 on 4/9/78, the Type A test was terminated with a calculated leakage rate at the 4

95% confidence level of 0.217+0.054%

per day, well below the allow-able.

The verification flow Was then started at an initial. flow rate of 0.900% per day.

The verification test commenced at 1100 on 1

.~

1 4/9/78 after completion of reactor vessel fill and cooldown operations.

(Note: During Type A and verification test data acquisition, the RHR system shutdown cooling flow was aligned to bypass the RHR heat ex-changer thus allowing a slow, relatively constant reactor vessel water heat-up.)

After five hours of test, the verification test leakage rate, 0.488%

per day, was not within the allowable limits and was also less than the average induced flow rate of 0.896% per day.

The Type A and verification test data and calculations were then rechecked, with no errors found in data entry or calculations.

(See Appendix A for Type A and verification test reports. )

Proper operation of the veri-I fication flow measurement system was verified during the data and calculation review.

A calibration check, in accordance with vendor procedure, of the twelve drybulb temperature measurement channels of the data acquisition system was then performed.

During this check, temperature channels 7 and 8 were both displaying 115 F with the system preamplifier at normal gain setting.

At half-normal gain setting the two ghannels displayed 74 and 75 representing temperatures of 148 F and 150 F respectively.

All other channels displayed the expected half-normal gain setting values.

It was therefore con-cluded, after consultation with the system vendor, that the outputs of these two temperature sensor (RTD) linear bridge networks were caturating the output of the system preamplifier at normal gain set-ting and had been doing so during most of the Type A test and all of the verification test.

Test personnel concluded that the high con-tainment temperatures at the sensor locations were due to insufficient cooling air flow caused by inoperation of three of the drywell cooler fans, and the Type A test should not continue without operating addi-tional fans.

Larger overcurrent devices were installed in the four drywell cooler fan breakers, and the four f ans were restarted.

Simul-taneous two mode (full and half-gain) temperature data acquisition continued for seven hours after fan restart.

From that time through Type A and verification test completion, two mode temperature data acquisition was used only wgen the full-gain temperature read-ing for any channel exceeded 112 F.

Following completion of reactor vessel fill and cooldown operations, the Type A test was restarted at 0530 on 4/10/78.

After eleven hours of test, the measured Type A leakage rate was steady at 1.4% per day.

As this value was 0.5% per day greater than the test allowable leakage rate, a second external survey of poten-tial leak paths was initiated.

During this survey, leakage was detected through the external containment vent path (required to subject the containment isolation valves to test differential pres-sure) for penetration No. 46, Demineralized Water.

A flowmeter type local leakage rate test on this vent yielded a leakage rate, with a 3/8" flowmeter bypass open, of at least 0.34% per day.

The vent isolation valve was shut stopping the leak.

No other leak paths were discovered.

l 2

The Type A test was restarted following reactor vessel fill and cooldown operations.

At 0715 on 4/LY78, the Type A test was term-inated with a calculated leakage rate at the 95% confidence level of 0.420+0.138% per day (Total-Time Method) and 0.427+0.029% per day (Mass-Point Method.)

Following reactor vessel fill and cool-down operations and a final calibration check of the drybulb temp-erature measurement system, a verification test flow rate of 0.917%

per day was established.

Three hours and twenty minutes into the verification test, a drywell cooler fan tripped and could not be restarted.

The verification test calculated leakage rate just prior to f an trip was 1.567% per day (Tctal-Time) and 1.509%/ day (Mass-Point), both within allowable limits.

After a forty-five minute stabilization period, the verification test was restarted with the same verification flow rate continuing through the stabilization period.

The verification test was successfully completed at 1830 on 4/11/78.

Following the verification test, the containment was de-pressurized through the standby gas treatment system.

III. DISCUSSION A.

Variable Volume Leakage Rate Calculations The residual heat removal (RHR) system could not be operated, in shutdown cooling mode, to maintain constant reactor coolant temperature.

The tests were therefore performed with RHR system flow bypassing the RHR heat exchanger allowing a slow steady reactor coolant tempera-ture increase during the data acquisition periods.

The containment free air volumg used in legkage rate calcula-tions was decreased 5.5 ft for each 1 F reactor coolant temperature rise.

Required reactor vessel fill and cool-down operations were performed prior to Type A and veri-fication test data accumulation.

The only mass transfer across the containntnt boundary including the closed RHR system extension of containment was therefore due to water or air leakage.

Both water and air leakage is accounted for in the integrated leakage rate calculations.

B.

Temperature Measurement System In Section II the malfunction of temperature measurement channels 7 and 8 during the initial Type A and verifica-tion test data acquisition periods was described with the corrective action taken to prevent a later similar occur-rence.

This malfunction resulted in the understatement of:

1) the containment average temperature at any given time, and 2) the rate of change of containment average temperature over the Type A and verification test data intervalc.

Both phenomena, but particularly the latter, resulted in a calculated leakage rate value that is less than the actual leakage rate.

The supplemental verification test, which is performed folicwing a Type A test to detect such a 3

system malfunction, yielded leakage rate results lower than the known imposed leakage rate.

The unacceptable verification test results thus led to detection of the temperature measurement system malfunction.

C.

Corrections to Type A Test Results Immediately following containment depressurization to atmocphere, the internal demineralized water system piping at Penetration No. 46 was inspected to determine the cause of excessive leakage during the failed Type A test.

A i

normally closed drain valve, not shown on the system P&ID, was found open.

The valve would have been closed during the test but as it was not shown on the system P&ID it was not included on the ILRT system valve lineup.

The external system was vented inboard of the outboard contain-ment isolation valve to preclude draining the demineralized water system outside containment.

This conservative line-up provided only one isolation barrier, the inboard iso-lation valve.

The open drain valve is installed inside containment between the inboard locked closed containment isolation valve and the containment penetration, thus establishing the leak path which had to be blocked to allow successful Type A test completion.

The drain valve was closed and a Type C test was performed on the penetration containment isolation valves.

The Type C leakage rate of 0.016% per day is added to the Type A test results.

Refer to Section IV.C.ll. for a tabulation of corrected Type A tact results.

No corrections to Type A or verification test calculations are required as a result of the post-test calibration verification, traceable to the National Bureau cf Standards, performed on the twelve resistance temperature detectors by the vendor.

The pressure suppression chamber (torus) atmosphere was saturated during the tests.

At saturation, the atmcsphere drybulb, dewpoint and wet-bulb temperatures all take on the same value.

Therefore, the more stable and accurate torus atmosphere drybttib temperature values (frca RTD channels ll&l2) were taken as dewpoint read-ings.

The devpoint temperature channels in the torus were monitored during the test for centinued evidence of torus atmosphere saturation.

GENERAL m

C.1e of the conditions of all operating licenses for water-cooled power reactors is that primary reactor containments shall meet the ccntainment leakage test requirements set forth in the Appendix J to ICCFR50 and the project tech specs.

The purposes of the tesis (Type A, B, and C) are to assure that (a) the leakage through the primary reactor containment and systems and components penetrating primary containment shall not exceed allowable leakage rate values as specified in the tech specs or associated bases and (b) periodic surveillance of reactor containment penetrations and isolation valves is performed so that proper maintenance and repairs are made during the service life of the containment,.and systems and components penetrating primary containment.

The satisfactory completion of Type B and C leak rate tests allows the discovery and elimination of leak paths thru the containment without pressurizing the entire containment

' structure as is done in an Integrated Leak Rate Test (ILRT).

Three Type 8 and C local leak rate test (LLRT) programs were satisfactorily performed during the time inter. val between the pre-operational ILRT and the first ' periodic ILRT.

Due to the long duration of the first operating. cycle, one LLRT program had to be performed prior to the first refueling shutdown in order to comply with the 2 year surveillance frequency set forth in Tech Specs.

The second and third LLRT programs were completed during.the first and second R/F Dutages respectively.

II. DISCUSSION The procedure used to perform local leak rate tests (LLRT's) on primary containment boundary components employs the air flow method.

This method determines the leakage rate by measuring the amount of makeup flow required to keep the test volume at a pre-set pressure which is maintained by a pressure regulator.

Following the completion of an LLRT, the measured leakage rate is

'he test adjusted as required to account for any differences between t

Pressure and/or temperature and the pressure and tempera ture at which the instrumentation was calibrated.

The following equations are used to determine the pressure and temperature correction factors:

= Atmospheric pressure (14.7) atm Rotameters are used to determine Type B and C leakage rates and are calibrated to i 1% (Full Scale) accuracy traceable to the National Bureau of Standards.

The rotameters used are of the following ranges:

22-220 ACCM, 220-2200 ACCM and 4-40 SCFH.

Efforts are made to measure leakages with the correct range rotameters to prevent obtaining inaccurate leakage rate readings.

Occasionally during the performance of a Type C LLRT it is difficult to determine which valve is leaking in a two or more valve boundary.

One method for determining this is by checking vents on the outboard side of each boundary valve as this is helpful in directing maintenance activities.

III. DETERMINING TCIAL CONTAINMENT LEAKAGE In order to detor-s.c3 atal containment leakage, it is initially required to detesmine t..e TYPE B and C leakages for each penetration.

Once penetration leakages are determined, the overall leakage for components penetrating the primary containment may'be determined by summing the Type B and C penetration leakages.

Penetration leakage is determined as follows:

Type B penetration leakages are determined directly from the test leakages when the penetration invoives only one test.

Wiien the penetration involves an inboard and an outboard component; however, the penetration leakage is equal to the greater of the two test values.

I

4 I

Type C penetration leakages include three types of tests:

~

a.

For containment isolation valves in series, tested individually, the renetration leakage is equal to tire i

measured test leakage of the isolation valve with the highest leak rate.

b.

For containment isolation valves tested simultaneously, the penetration leakage is equal to the total leakage measured.

c.

For containment isolation valves tested individually that are in parallel, the penetration leakage is the sum of the individually measured test leakages.

IV.

ACCEPTANCE CRITERIA The acceptance criterion for Type B and C local leak rate tests is set forth in 10CFR50 Appendix J and the project Tech Specs as being 60% La for all containment penetrations and isolation valves subject to Type B and C testing.

Specific acceptance criteria exist only for Main Steam Isolation Valves (11.5 SCFH/ valve) and the Drywell Airlock Inner Space (5% La).

Due to the fact that the 60% La is an overall limit, the possibility exists in that the majority of the containment leakage could be leaking through one highly degraded valve and still be within the 60%

limit.

Although the uniformity of leakage through the containment penetrations is relatively unimportant, it is not desirable lo have a case where the majority of containment leakage is being emitted through one penetration.

Because of this, an effort is made to limit the leakage through penetrations by assigning an expected value for each test.

This value is not a limit but serves as a guideline to prevent the aforementioned condition.

INTRODUCTION Section V.B.3. of 10CFR50, Appendix J requires a summary report of Type A test leakage rate results that failed to meet test acceptance criteria, which includes an analysis and interpretation of test data, the instrumentation system error analysis and a description of con-tainment conditions causing test failure.

The following information is reported in response to this requirement.

DISCUSSION The initial Type A test f ailed because of excessive leakage through two separate leaku, the drywell head flange and an open drain valve in the demineralized water system inside containment, between the containment penetration and the inboard containment isolation valve.

The drywell head leakage was the result of insufficient torque ap-plied to the head bolts during installation just prior to the start of the Type A test.

A Type B test, indicating no leakage, had been performed following drywell head installation and prior to contain-ment pressurization for the Type A test.

The drywell head leak was detected during an external containment leak survey performed after initially reaching test pressure in the containment.

The leakage was excessive enough to cause containment pressure to decay at a 1 psi per hour rate.

No leakage rate calculations were performed due to the obvious excessive leakage and the high pressure decay rate.

No other leaks were detected during this initial survey.

The containment was depressurized to atmospheric pressure and the head bolts were detensioned.

The drywell head bolts were then tensioned por the drywell head ins tallation procedure, HNP-1-6705.

The pro-cedure included applied torque measurements and head flange gap measurements.

A Type B test was again performed,. indicating no leakage following the head bolt tensioning procedure.

The contain-ment was repressurized to test pressure anc no leakage was detected through the drywell head flange.

The open drain valve in the demineralized water system was not shown on the system P&ID and resultantly was not included in the system lineup for the Type A test.

The valve would have been shown closed on the valve lineup and therefore positioned and tagged ac-cordingly.

The actual valve lineup which contributed to initial Type A test failure is shown in Sketch 1 below.

The system containment isolation valves are locked closed valves P406 inside containment rnd F353 outside containment.

The system was drained inboard of F353 and vented to containment and outside atmospheres through valves F343 and F407 respectively.

This con-servative lineup, which includes the use of only one (F406) of the two available containment isolation valves for containment isolation, was used for the Type A test to preclude draining the external de-mineralized water system.

Drain valve F3002 was the open valve which provided the leakage path from containment atmosphere through the penetration and valve F372 to outside atmosphere through external system vent at valve F407.

The leakage was stopped.by closing valve F407.

The final lineup with F407 closed included the use of F353 as the only isolation barrier but did not provide an external system vent.

The leakage rate from a Type C test performed on the pene-tration after Type A test completion, with valve F3002 closed, was therefore added to the successful Type A test results.

This leakage rate was 800 ACCM at a test pressure of 59 psig or 0.016% per day.

The Type A test data and data analysis showing the excessive leakage rate prior to finding and stopping the leak are shown in Table C-1.

Valve F3002 has been added to system drawings to prevent a similar ruture occurrence.

The instrumentation system error analysis is based on the Instru-4 I

montation Selection Guide (ISG) formula from ANS N274, Draft No.

2, Revision 2 - May 15, 1973 " Containment System Leakage Testing i

Raquirements".

The formula is:

The error acacciated with the instrumentation system, ISG, is

+ 0.037% per day.

A::S N274 requires that the ISG shall not exceed i

The comparison below shows the ISG is much less than the l

As stated in ANS N274 the ISG forrtula is not based on a statistical analysis of the actual leakage rate data and is not added to the leakage rate value.

The ISG value is used only for instrument selection and loss of sensor criteria.

It is reported per the speci-fic requirements of 10CFR50, Appendix J, Section V.B.3.
