4.1' CONTAINMENT INTEGRATED 'rRUCAGE RATE TEST (CILRT):

The Unit Two 1991 CILRT was successfully completed on May 27, '1991.

The final upper confidence limit (UCL) leakage,. including the required penalties, was.041887 wt

%/ day.

The test results demonstrated that the integrity

.of the containment structure satisfied the criteria set forth in 10CFR50, Appendix J, Paragraph III. A.5. (b). (2).

As part of preparations for the CILRT, component cooling water to the containment air recirculation fans was secured approximately 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months prior to pressurization.

Securing component cooling water causes containment air temperature at the start of the CILRT to be close to the containment' structural temperature thereby reducing the containment stabilization time.

1 A one point in-situ calibration check performed on the temporary moisture analyzers (5) installed in containment r e v e a l e d ~ t h a t - o n e -~ m o i s t u r e analyzer (#8) was reading erratically.

It was decided to remove the moisture analyzer computer point from the CILRT computer program.

The CILRT computer program ' automatically reassigns the weight factor for the rejected analyzer to the other moisture. analyzers in that zone.

As-required by Attachment 2

of 02-NPT-CT-101, Reactor Containment Building Integrated Leak Rate Test, a Instrumentation i

Selection Guide (ISG) recalculation was performed to determine the minimum test duration.

The minimum CILRT duration, minus.the one rejected sensor, was 11.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months .

As part of the containment leakage rate test program, an air test is performed every refueling on the service water side of the Recirculation Spray Heat Exchangers (RSHX).

Air tests are performed to verify integrity of service water piping and components associated with each RSHX.

The test of the "C"

RSHX revealed excessive leakage from a Service Water (SW) check valve gasket located inside containment. A replacement gasket was not i

available at the time to pressurization for CILRT), so the lines were(prior blanked in Safeguards outside containment and a vent was opened inside contaihment. No CILRT penalty was added.for blanking these lines because the RSHX ' Service Water piping and components inside containment are considered a closed system.

Because it Tis a closed system, the valves associated with these penetrations are not required to be Type C tested.

Following completion of the CILRT, the check valve gasket was replaced and a satisfactory air test was performed to i

verify leak tight integrity of "C" RSHX SW piping and components prior to unit startup.

SUMMARY

(CQl(TINUED) :

On May 24,

1991, a

final containment walkdown was performed at 0045 hours5.208333e-4 days 0.0125 hours 7.440476e-5 weeks 1.71225e-5 months .

Containment pressurization commenced at 0220 hours0.00255 days 0.0611 hours 3.637566e-4 weeks 8.371e-5 months on May 24, 1991 and continued i

until 1311 hours0.0152 days 0.364 hours 0.00217 weeks 4.988355e-4 months on May 24, 1991 with a peak containment I

pressure of 61.366 psia.

During pressurization, the "C" containment air recirculation fan tripped off line on high current overload at 0300 hours0.00347 days 0.0833 hours 4.960317e-4 weeks 1.1415e-4 months . The "B" containment air' recirculation -fan and the "A"

containment air i

recirculation fan were secured prior to exceeding 200 amps, at 0321 hours0.00372 days 0.0892 hours 5.30754e-4 weeks 1.221405e-4 months and 0530 hours0.00613 days 0.147 hours 8.763227e-4 weeks 2.01665e-4 months respectively.

After j

the "A" containment recirculation fan was secured, a i

remote fire watch for containment.was established in i

accordance with Attachment 14 of 02-NPT-CT-101.

p i

The containment. temperature stabilization criteria in I

L of 02-NPT-CT-101 was met at 1749 hours0.0202 days 0.486 hours 0.00289 weeks 6.654945e-4 months . The CILRT started at 2330 hours0.027 days 0.647 hours 0.00385 weeks 8.86565e-4 months on May 24, 1991.

During the course of the pressurization

period, stabilization period, and throughout the CILRT, extensive leak checks were performed by incpecting potential leakage paths such as the mechanical -penetration area in the Auxiliary Building, the electrical penetration area, the personnel and equipment air locks, safeguards, safeguards Valve

Pit, Fuel Building-area and Containment Purge MOV's located outside containment. Two electrical penetrations indicated a small increase in pressure and minor leakage observed ' through the inside of Containment Purge was Supply MOV's using an LMC located outside conteinment.

No other'significant leakage paths were discovered.

The CILRT leakage test was successfully completed at 2400 hours0.0278 days 0.667 hours 0.00397 weeks 9.132e-4 months on May.25, 1991 with a UCL leakage of.041452 wt l

%/ day.

With the Type.C test penalties added to the test l

result, the final leakage was 0.041887 wt 4/ day.

In accordance with 0-NPT-CT-107, Data Collection During Type A Test, the levels of tanks and vessels associated l

with systems in containment were monitored hourly during the entire CILRT.

Overall change in containment volume

.was an increase of approximately 279 ft3 due to changes in tank / vessel / sump levels during the CILRT.

This l

equates to having to subtract.000155 wt 4/ day from the CILRT results which results in a final leakage of.041732 wt %/ day. Taking a conservative approach, this change in not free volume was not factored into the final CILRT results.

4.2 SlifERIEQSED VERIFICATION TEST:

I l

The superimposed verification test was started at 0039 hours4.513889e-4 days 0.0108 hours 6.448413e-5 weeks 1.48395e-5 months on May 26, 1991 with a leakage of approximately 5.00 SCFM on the flow meter.

The stabilization period for the. superimposed verification test ended at 0239 hours0.00277 days 0.0664 hours 3.95172e-4 weeks 9.09395e-5 months on May 26, 1991.

At that

time, leakage l

calculations were started. The superimposed verification l

test then continued for approximately 17.75 hours8.680556e-4 days 0.0208 hours 1.240079e-4 weeks 2.85375e-5 months .

The final superimposed leakage rate value was.114287 wt

%/ day and satisfactorily met the acceptance criteria of 02-NPT-CT-115, Superimposed CILRT Verification Test.

Depressuri".stion of containment commenced at 2250 hours0.026 days 0.625 hours 0.00372 weeks 8.56125e-4 months on May 26, 1991 and was completed at 0752 hours0.0087 days 0.209 hours 0.00124 weeks 2.86136e-4 months on May 27, 1991.

The post CILRT containment inspection was completed at 1238 hours0.0143 days 0.344 hours 0.00205 weeks 4.71059e-4 months on May 27, 1991.

4.3 JACAL TMKAGE RATE TESTS (r T.RT) :

6.0 TEST DESCRIPTION:

I 6.1 EOUIPMENT USED The containment was pressurized utilizing a temporary air I

pressurization rig which tied into the containment purge ventilation duct.

The ri oil-free air compressors, g consisted of 8 diesel driven 2 aftercoolers and 1 air dryer.

j The rig was capable of supplying up to 10,000 SCFM of air to containment during the pressurization phase.

Cooling water for the aftercoolers and air dryer was supplied by the station's chilled component cooling system.

The l

pressurization rig was satisfactorily checked out prior j

to pressurization in accordance with Attachment 4.0 of l

02-NPT-CT-101.

l l

Containment temperature was monitored throughout the Type A Test by the use of 22 permanently mounted Resistance Temperature Detectors (RTD's) whose output is fed to the P250 computers.

The normal span of these RTD's was changed for the test by utilizing a temporary resistance bridge that was installed on the P250 computer. The span was narrowed to 60-120 degrees Fahrenheit to allow for j

greater sensitivity in recording containment temperature.

l l

Station computer input calibration procedure, 2-CAL-753, was performed on each RTD input signal to each units P250 l

computer.

A decade box was temporarily installed on the P250 computer which simulated the resistance reading for each RTD inside containment.

The computer was then checked to ensure that the proper output for each RTD was l

obtained when the resistance was varied.

A three point calibration at 60 degrees, 90 degrees, and 120 degrees Fahrenheit was performed within 6 months on the RTD's to

[

l ensure their accuracy.

A one point local verification check of the RTD's using a standard traceable to NIST was l

performed prior to the CILRT using station procedure O-NPT-CT-103, Calibration Check For RTD's and Moisture Analyzers".

6.1 EOUIPMENT USED (CONTINUED)

Containment dewpoint temperature was monitored by five (5) Ondyne moisture analyzer probes located throughout containment.

Readout devices with a-tie-in to the P250 computers were located in the electrical penetration area.

The Ondyne analyzers use the principle whereby the temperature.of the detecting surface on the probe is cooled by a thermoelectric device-to the point where condensation forms.

When condensation' is detected, cooling is controlled to hold 'the surface at the condensation temperature and then the surface temperature is measured using a

platinum RTD.

This surface

' temperature is the dewpoint temperature of the air next to the probe.

i The moistura analyzers were calibrated within six months of the CILRT by the vendor and > their accuracy was certified as being traceable to NIST.

An additional one point check was performed for each analyzer using station procedure 0-NPT-CT-103.

Containment pressure was monitored by the use of two (2)

Mansor Quartz manometers.

These manometers use the Containment Leakage Monitoring (LM) system through leakage monitoring connections on the 13' level of the Auxiliary Building. The signal from these manometers was fed into the.P250 computers.

The manometers were' calibrated within six months of the CILRT by the original manufacturer with the accuracy being certified as being i

traceable to NIST.

'l i

l A Hastings linear mass flowmater was used to monitor flow

~

for the superimposed verification test which followed the Type A Test.

The flowmater measures flow without any corrections being needed for pressure and temperature.

Flow is displayed and totalized at the flowmeter which is installed in the LM system on the 13' level of the Auxiliary Building.

The LM piping then ties into the service Air (SA) piping penetration which is vented inside containment.

The flowmeters accuracy was l

certified as being traceable to NIST by the original manufacturer within six months of the CILRT.

l Attachment 6.1 lists pertinent information - for the i

instrumentation that was used during the CILRT.

i 6.2 a-

6.2 CILRT PROGRAM - P250 COMPUTrE The ILRT program on the P250 computer gathers and logs the required data during the CILRT..The data is. printed

- out.in log format every 10 minutes and is then input into the PC ILRT program.

The ILRT program on.the P250 computer consists of three l

sub-programs.

The programs are run on both units P250 computers during the Type A Test.

The program on Unit One's computer would be used as backup if Unit Two's computer falls.

The three programs are

ILRTMANO, ILRTDAT2, and ILRTPRT2.

The ILRTMANO program is used to convert the BCD output of the quartz manometers into floating point numbers.

The ILRTMANO program reads six BCD digits for. each quartz manometer via a direct channel read and converts these i

l BCD signals into' floating point values which are'placed l

in calculated points.U0962 and UO963 of the-P250 computer.

Each quartz ' manometer is scanned on a two second frequency.

.The ILRTDAT2 program uses the 22 containment RTD readings, 5 moisture analyzer readings and 2 pressure readings to apply the appropriate weight factors and to perform sensor validity checks.

These values are obtained from.the P250 Average and Integrate (A&I)

I program which calculates a simple average for each of the twenty-nine (29) sensors by summing the instantaneous.

readings taken during a ten minute period and dividing the totals by the number of readings taken.

The RTD's and moisture analyzers are scanned every 20 seconds by the A&I program.

The ILRTDAT2 program also performs sensor checks by l

checking the difference between the ten minute averages l

of sensors within the same zone against a maximum limit.

l When the maximum limit is exceeded, the program notifies the operator via an error message printed out on the alarm typewriter to check the zone.

If a sensor has l

malfunctioned, the operator can direct the program to stop scanning the faulty sensor and to reassign the failed sensors weight factor to the remaining sensors in its zone.

6.3 t

l-1

a 6.2 CTLRT PROGRAM - P250 COMPUTER (CONTINUED)

ILRTDAT2 prints three sets of containment data every ten minutes.

First, the instantaneous value of each sensor is printed on the trend typewriter.

These data points are. used by the Test Engineers for trend evaluation.

Second, the containment averaged parameters based on the ten minute averages of sensor readings are printed to the i

alarm typewriter.

Third, the containment averaged i

i parameters based on instantaneous sensor readings are i

printed to the alarm typewriter.

The containment averaged parameters (those based on instantaneous sensor readings) and time are input to the PC ILRT for the actual leak rate calculation. These data are also stored 1

on the P250 disk drive for up to 25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months .

l The ILRTPRT2 program prints a formatted log of the containment averaged data that is calculated and stored

'on disk by ILRTDAT2.

ILRTPRT2 is executed automatically by ILRTDAT2 either after 25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months of data are collected or when a print request flag has been set.

ILRTPRT2 can also be executed manually from the P250 programmer's console.

The log contains containment averaged data based on both time averaged sensor readings and instantaneous sensor readings.

6.3 CILRT PROGRAM - PC COMPUTER

~

The CILRT program on the PC computer is used to calculate and plot the change in containment air mass versus time.

Input data for the program is obtained from the plant process computer (P250) data collection program.

The variables which are input into the PC program are time, containment

pressure, dewpoint temperature and containment temperature.

An auxiliary PC program (CONVERT) is used to transfer the PC ILRT input data automatically from the P250 printed output.

CONVERT reads the captured alarm typewriter output.

It discards all information except the tabular listing of containment averaged data based on instantaneous sensor values.

The containment data is then reformatted and stored in a data file suitable for input to PC ILRT.

PC ILRT has options for performing various functions which enable the user to calculate results, list data set

members, input additional data seta members, modify existing data set members and to delete data set members which are not needed.

6.3 CILRT PROGRAM - PC COhruTER (CONN nuzD)

In the~ calculation mode, the user-has the option of i

performing either mass - point, total time or point-to-

{

point analysis.

Mass point was used for this test because Amendment No. 120 to Technical-Specifications,

)

which was approved by the NRC on May 24, 1988 modified Section 4.4 to reflect-the use of the Mass Point method for calculating containment leakage rates.

1 The Mass Point method calculates the air mass at a series of points in time, and plots.it against time.

The' air-mass in containment was -calculated using pressure, temperature, and dowpoint data which was collected by the -

P250 computers.

Air mass is calculated using the ideal gas law formula.

The formula is as follows:

M = 144 V (P-Pv)

R T

l

\\

Where:

M = air mass, lbm l

P = total' pressure, psia PV = vapor pressure, psia R = 53.35 ft-lbf/lba 'R (for air)

T = average containment temperature, R V = containment free volume, 1.8 x 10 CU FT j

After the mass is calculated, the results are correlated as a function of time by using a least-squares-curve fit J

of the form:

M = At+B Where:

M = estimated mass A = least' squares slope - dM/dT B = least squares y - intercept - Mo The slope (A) and y-intercept (B) are used to calculate the leak rate.

The~ leakage rate is calculated after the muss is plotted as a; function of time using a least-square fit to determine the slope, A = dM/dT.

Leak rate r

is expressed as the fre.ction of mass lost pet-24 hours out of containment:

Leakage Rata = (dM/dT)/Mo x (-2400)

Where dM/dT is the slope-of the mass least-square curve and Mo is the y-intercept.

6.3 CILRT DROGRAM - PC COMPUTEx (CONTINUED)

The sign convention is such that a positive leakage rate value is an indication of outward leakage.

The units for this value are in wt 4/ day.

A 95 percent confidence limit is calculated for each value using a Student's T distribution.

The sum of the 95 percent confidence limit and leakage rate is the Upper Confidence Limit (UCL).

The output from the program will then print out the time, mass, maasured leakage, estimated leakage, confidence limit and the Upper Confidence Limit for each data set.

4 7.0 TEST RESULT ANALYSIS i

7.1 CILRT i

i The CILRT was satisfactorily completed at 2400 hours0.0278 days 0.667 hours 0.00397 weeks 9.132e-4 months on May 25, 1991.

The Mass Point method was used to analyze the data to ensure that containment integrity met the requirements of 10CFR50, Appendix J.

Figure 7.1 and 7.2 show the trends of containment mass and UCL leakage during the CILRT..5 lists the final CILRT results along with the required Type C penalties.

.1 and 7.2 list the input data and mass point i

CILRT results using instantaneous data from the plant 4

process computer (P250).

7.2 SUPERIMPOSED VERIFICATION TEST i

The supplemental verification test was satisfactorily performed using 2-NPT-CT-115, " Superimposed Verification Test".

Figure 7.3 shows a plot of leakage versus time for the verification test.

Included on the plot are the upper and lower limits for the verification test results.

l The equation used to ensure that the verification test 1

was acceptable is:

j (Lam + Lo

.25La) S Lc 5 (Lam + Lo +.25La)

Where:

Lam = Type A calculated leakage

,~

Lo = Superimposed leakage rate on containment Le

= Leakage during verification test (computer)

La

= Maximum allowable leakage.3 and 7.4 has a listing of the input data and test results for the verification test.

i Substituting actual test results, the above equation

{

turns out to be:

(. 039545+. 0981. 025) $.114287 s (. 03954 5+. 0981+. 025) i

.112645 5 114287 s.162645 As shown above, Lc falls within the upper and lower limits of the equation.

8.0 IDCAL T.RAK RATE TESTS (TYPE B AND C)

Type B and C tests were performed on containment penetrations l

prior to the CILRT.

The As-Found and As-Left test results for these penetrations are shown in Attachment 8.1.

If any j

repairs were required, a description is included.

Also included in Attachment 8.1 are Type B and C test results for tests which were performed since the last CILRT in November 1986.

l The total As-Found Type B and C leakage value, using maximum L

pathway leakages, during the 1991 Refueling Outage was 680.99 l

SCFH which is above the maximum leakage of 0.6.L, (180 SCFH) as specified in 10CFR50, Appendix J, Section III.B.3.(a).

The majority of the As-Found leakage can be attributed to two penetrations.

These two penetrations each had an inboard i

containment isolation valve leakage of 305 SCFH.

The l

penetrations / valves were Penetration 38 (02-DA-TV-200A) and Penetration 33 (02-DG-TV-208A).

The outboard containment isolation valves for these two penetrations (02-DA-TV-200B and 02-DG-TB-208B) had an As-Found leakage rate of 0.045 SCFH and 0.56 SCFH respectfully.

Therefore, the maximum leakage that could have passed through these penetrations using the minimum pathway. leakage criteria was 0.605 SCFH.

The total As-Found Type B and C leakage value during the 1991 Refueling Outage was 20.38 SCTH when using the minimum pathway leakage criteria.

The corrective action taken to reduce the Type B and C leakage below the 0.6 L value was to repair and/or replace valves which had leak, age above the maximum allowable leakage specified in 02-OPT-CT-201, " Containment Isolation Valve Local Leakage Rate Testing" (Type C Containment Testing).

Following these repairs the final As-Left Type B and C leakage, using the maximum pathway leakage criteria, was 26.17 SCFH which is well below the 0.6 L, value of 180 SCFH.

9.0 AS-POUND CILRT ANALYSIS i

t.

l An As-Found analysis has.been performed on the CILRT.

The L

. purpose is to determine what the actual CILRT leakage rate would be if the CILRT had been performed at the beginning of the outage prior.to any repairs to Type B and C penstrations.

)

i The.As-Found analysis is-performed using-the following criteria:

1)

The leakage savings was -calculated for each penetration that was repaired and/or replaced.

2)

The leakage savings is the difference between the pre-repair minimum pathway and post-repair minimum pathway leakages.

3)

Minimum pathway leakage is the ' lowest leakage of the inside or outside valve grouping for the penetration in question.

i 4)

If there were no repairs or replacements, a zero leakage savings'is assessed to the penetration.

5)

If the post-repair minimum leakage is greater than i

pre-repair minimum pathway' leakage, a' leakage savings of zero is assigned to the penetration.

6)

The not leakage savings (wt 4/ day) is added to the I

final CILRT test results.

An analysis ' was performed on those penetrations that are considered cred3b3 t leakage paths during the first hour of the j

accident, pricc to the

. containment returning to 1

subatmospheric pressure.. The penetrations identified by note 1 through 4 in Attachment 9.1 are excluded as credible leakage sources.

The analysis and technical justification for excluding these specific penetrations was approved by the NRC in correspondence dated November 21, 1988 (serial #88-787).

As noted in Attachment 9.1,'the as-found CILRT leak rate was 0.045299 wt %/ day which satisfies the acceptance criteria of 10CFR50, Appendix J.

SUMMARY

i NOTES:

1)

This line is from the charging pump header and is used to supply the loops.

The charging pumps are used as the high head safety injection pumps and this line (penetration) remains pressurized during post accident conditions.

The cycS system

valves, piping and components have been designed to permit essentially zero leakage.

Periodic surveillance is performed to verify that leakage is within specifications.

This line is from the low head safety injection pump header and is used to supply the loops and this line (penetration) remains pressurized during post-accident conditions.

The safety injection system valves, piping and components have been designed to permit essentially zero leakage.

Periodic surveillance is, performed to i

verify that leakage is within specification.

3)

The recirculation spray system is designed to operate after the DBA LOCA to depressurize the containment to i

subatmospheric pressure.

The sump lines are filled with l

water and would prevent atmospheric out. leakage either through operation and/or static head.

Periodic surveillance is performed to verify that leakage is within specifications.
