1.0 PURPOSE The purpose of this report is to present a description and an analysis of the results from the Type A test that was performed on Surry Unit 1 in July 1986 as required by Paragraph V.B of 10CFR50 Appendix J.

Included in the report are the results from Type Band C tests that were performed since the last Type A test in April 1983.

SUMMARY

TYPE A TEST The CILRT which was performed on Unit 1 is considered to be a complete success.

The test results demonstrated that the integrity of the containment structure satisfied the criteria in 10CFR50 Appendix J, Paragraph III.A.5.(b).(2).

The calculated leakage for the test was.055951 wt%/day which is below the acceptance criteria of.075 wt%/day.

The success in this test was a result of the ongoing improvements that are being made to the station's Type A, Band C testing program following the successful CILRT on Unit 2 in June 1985.

The CILRT commenced on July 2, 1986 with containment closeout occurring at 0645 hours0.00747 days <br />0.179 hours <br />0.00107 weeks <br />2.454225e-4 months <br />.

Prior to the start of pressurization, MOV-CS-101A (Penetration 64) was removed and the line blanked due to excessive valve seat leakage following As-Left Type c testing and because the amount of time required to repair the valve would have impacted the start of the CILRT.

The valve seat had been damaged following limit switch adjustments.

The valve was reinstalled after the CILRT and its leakage following repairs(l.4 SCFH) was added to the final results.

Testing of the personnel hatch prior to the start of pressurization indicated that a significant amount of leakage was occurring past the emergency escape hatch which is located on the inner door of the personnel hatch.

The station, immediately initiated repairs to try to reduce the leakage.

The post repair test results on the personnel hatch was 15.13 SCFH.

Checks made by test personnel verified that none of the leakage was occurring past the outer door of the personnel hatch into the Auxiliary Building.

All the leakage from this test was past the emergency escape hatch o-rings into containment.

A decision was made to continue on with the CILRT with the emergency escape hatch in its existing condition and to repair it following the CILRT.

As a part of procedure ENG-70.2 "Data Collection During Type A Test", a pressure gage was installed on the personnel hatch to monitor its internal pressure during the CILRT.

Containment pressurization commenced at 2041 hours0.0236 days <br />0.567 hours <br />0.00337 weeks <br />7.766005e-4 months <br /> on July 2, 1986 and continued until 0654 hours0.00757 days <br />0.182 hours <br />0.00108 weeks <br />2.48847e-4 months <br /> on July 3, 1986 with a peak containment pressure of 61.248 psia.

Containment temperature stabilization criteria as stated in 1-PT-16.3 were met at 1204 hours0.0139 days <br />0.334 hours <br />0.00199 weeks <br />4.58122e-4 months <br /> but the actual start of the CILRT test period was delayed until 1754 hours0.0203 days <br />0.487 hours <br />0.0029 weeks <br />6.67397e-4 months <br /> on July 3, 1986.

This was due to the continued decline of average containment temperature and dewpoint temperature.

In addition, B Containment Air Recirculation fan tripped off line lengthening the stabilization period.

2.1

The CILRT was started at 1754 hours0.0203 days <br />0.487 hours <br />0.0029 weeks <br />6.67397e-4 months <br /> with the calculated containment leakage slowly declining from an initial.14 wt%/day.

At approximately 2230 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.48515e-4 months <br />, average containment dewpoint became unstable.

This was due to the oscillation of moisture analyzer No. 7.

It was not until approximately 0020 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> on July 4, 1986 that average dewpoint temperature had become stable again.

If the CILRT had been run from the initial start time of 1754 hours0.0203 days <br />0.487 hours <br />0.0029 weeks <br />6.67397e-4 months <br /> on July 3, 1986 until 0026 hours3.009259e-4 days <br />0.00722 hours <br />4.298942e-5 weeks <br />9.893e-6 months <br /> on July 5, 1986, the calculated containment leakage would have been.068 wt%/day which is below the acceptance criteria of.075 wt%/day.

The CILRT was restarted at 0024 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> on July 4, 1986 due to this fluctuation in average dewpoint temperature.

The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> CILRT which then ran from 0024 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> on July 4, 1986 through 0024 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> on July 5, 1986, can be broken down into three segments according to the varying slopes of the leakage line(See Attachment 5.2).

The first part of the CILRT which ran from 0024 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 0324 hours0.00375 days <br />0.09 hours <br />5.357143e-4 weeks <br />1.23282e-4 months <br /> on July 4, 1986 had an average leakage of.102 wt%/day.

This leakage value was calculated by determining the mass lost during the time period and converting its units to wt%/day.

During the next nine hours, which ran from 0324 to 1224 hours0.0142 days <br />0.34 hours <br />0.00202 weeks <br />4.65732e-4 months <br />, containment leakage averaged.088 wt%/day.

It was during the last twelve hours of the test, from 1224 to 0024 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> on July 5, 1986 that leakage averaged.024 wt%/day.

During the nine hour period when leakage averaged.088 wt%/day, an extensive effort was made to identify and quantify all possible leakage paths.

Leakage from penetrations that were vented during the test totalled approximately 2.5 SCFH or.00084 wt%/day.

The personnel hatch was pressurizing during the CILRT due to the leaking emergency escape hatch on the inner door, but leakage into the hatch averaged a relatively stable 3.86 SCFH or.0013 wt%/day throughout the test.

The leakage from these two sources totaled approximately.002 wt%/day which was only a small part of the total leakage during that time period.

Other possible leakage paths were checked with no leakage being identified.

A review of previous CILRT results indicates that the test performed in 1981 exhibited similar leakage characteristics as the 1986 test.

During the last 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> of that test, leakage averaged.09 wt%/day for nine hours then changed to approximately.04 wt%/day for the next 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />.

It appears that this leakage trend may be an inherent characteristic of Unit 1 containment during CILRTS.

This could be due to the amount of time that it takes for ingassing(air filling voids within insulation,concrete or piping) to occur.

2.2

During the CILRT, walkdowns of control room indications identified various containment isolation valves that had indications other than the required closed position.

Valves TV-SS-104A and TV-SS-lOlA were indicating open while TV-SS-lOOA and TV-DA-lOOA indicated in the intermediate position.

Following the CILRT, an investigation was made to determine the cause for the intermediate or open indication of these valves.

For the Sampling valves, the problem was found to be with the limit switch.

The limit switches, which are Microswitch brand, actuated without any actual movement of the valves.

It was determined following the CILRT that containment pressure during the CILRT was pressurizing the space between the limit switch head and the flexible seal which is between the head and switch body.

This then caused the seal in each limit switch to flex, thereby pressing against the electrical contacts assembly and actuating it, thus giving the faulty valve indication. To correct this problem, it is planned to replace these valve/limit switch assemblies with Target Rock valves during the next outage of sufficient length.

The problem with TV-DA-lOOA was found to be with the actuator.

The actuator was removed from the valve following the CILRT and sent to the manufacturer for a determination of the problem.

It was completely disassembled without any problems being identified.

Later inspections of the installed actuator by station personnel revealed that the nut holding the limit switch arm had worked itself loose thereby not allowing it to make proper contact.

It is thought that this could be the cause for the faulty indication during the CILRT.

To prevent this limit switch arm from working itself loose again, flats will be machined on new limit switch arms to prevent their movement even if the nuts do come lose.

In addition, the new valves have experienced higher seat and packing leakages than expected when Type c testing following the CILRT was performed.

It was determined by the manufacturer that the cause of this leakage was galling of the valve's ball.

The galling occurred because the tolerances of the trunion bushings were not tight enough, thereby allowing excessive movement of the valve stem.

It is also suspected that the slack in the stem translated back to the packing, thereby causing the packing gland follower nuts to work themselves lose.

This is the reason why the valves had excessive packing leakage when Type c tested.

To resolve these problems, the trunion bushings will be machined on both the valves currently installed in Unit 1 and the new valves to be installed in Unit 2.

A locking device will also be installed on the packing gland follower nuts to prevent them from working lose.

2.3

e VERIFICATION TEST The superimposed verification test commenced at 0026 hours3.009259e-4 days <br />0.00722 hours <br />4.298942e-5 weeks <br />9.893e-6 months <br /> on July 5, 1986 with stabilization being complete at 0230 hours0.00266 days <br />0.0639 hours <br />3.80291e-4 weeks <br />8.7515e-5 months <br />.

The actual verification test then ran for 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> until 0930 hours0.0108 days <br />0.258 hours <br />0.00154 weeks <br />3.53865e-4 months <br /> on July 5, 1986.

The test period was greater than the minimum of 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> that is required for a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> CILRT.

Due to the significant change in leakage during the CILRT, as mentioned previously, the composite leakage (L) during the verification test could not meet the acceptanceccriteria using the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> test results.

See.1 for an example of the verification test acceptance criteria using 24 and 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> CILRT results. _

When the test results from the last 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of the CILRT are used in the verification test acceptance criteria, L easily falls within the limits.

The basis for the decis!on to use the last 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is that it is felt that the leakage

In addition, the leakage trend from the 1981 CILRT provides support to this.

Containment depressurization'started at 1215 hours0.0141 days <br />0.338 hours <br />0.00201 weeks <br />4.623075e-4 months <br /> and was completed at 2210 hours0.0256 days <br />0.614 hours <br />0.00365 weeks <br />8.40905e-4 months <br /> on July 5, 1986.

CONCLUSION Since all applicable acceptance criteria were met,the normal CILRT schedule as specified in paragraph III.D.1.(a) of 10CFR50 Appendix J should continue.

LOCAL LEAK RATE TESTS (TYPE BAND C)

Local leak rate testing was conducted on containment penetrations in accordance with the stations approved Type B and C test procedures..1 summarizes all the local leak rate tests that were performed since the 1983 refueling on Unit 1.

In addition, an AS-FOUND Type A test analysis is included in this section which analyzes the effects that repairs to containment penetrations had on the final CILRT results.

4.1

TEST EQUIPMENT AND INSTRUMENTATION The containment air pressurization system consisted of eight portable compressors producing oil-free air which was piped through two aftercoolers lined up in parallel and through a refrigerated air dryer.

Miscellaneous instrumentation and control valves were used to monitor and control the containment air pressurization system while the system was in service.

The air flow rate for the containment air pressurization system was approximately 10,000 SCFM.

The following.special test equipment was used to monitor various plant parameters which were needed to perform calculations of containment leakage during the Type A test:

A)

Absolute pressure quartz manometers B)

Moisture analyzers C)

Resistance temperature detectors D)

Hastings flow meter Calibration and/or functional test results of the test instrumentation listed above are shown in Attachment 4.2..3 shows the locations of the RTD's used during the CILRT..4 shows the locations of the moisture analyzers used during the CILRT~

All instrumentation except the flow meter have inputs into the plant's P-250 computer for data trending and calculations.

CILRT PROGRAM -

P-250 COMPUTER The integrated leakage rate testing program is loaded on both Units' P-250 computers.

The P-250 gathers and analyzes data received from the instruments used during the CILRT.

The CILRT program enables the P-250 to scan all analog inputs in a pre-programmed review, changes the values of the inputs into engineering units and keeps these values in memory for retrieval by the plant engineers and the CILRT program.

The following instrumentation was monitored by the P-250 computer during the CILRT:

INSTRUMENTS 24 Resistance Temperature Detectors 5 Moisture Analyzers 2 Quartz Manometers SCAN RATE (SEC) 20 20 2

The P-250 digital trend function was used to record the instantaneous values of the CILRT instrumentation.

The trend function ran every 5 minutes.

The P-250 Average and Integrate

• .program was used to calculate a ten minute average of the instrumentation readings.

4.2

'~

These averages were used as input into the CILRT programs.

The

cILRT program then calculates weighted averages for containment temperature, vapor pressure, dewpoint temperature and air mass.

The program runs every ten minutes and also performs sensor validity checks.

CILRT MAINFRAME COMPUTER PROGRAM The output from the P-250 computer is manually entered into the mainframe computers CILRT program.

The mainframe computer CILRT uses these values to perform the necessary leak rate calculations.

-The analysis performed can either.be mass point or total time.....

CILRT RESULTS -

MASS POINT ANALYSIS Upon completion of the CILRT, the mass point method of analysis was used to demonstrate that the containment leak rate was less than the allowable limit of 0.75 La.

The air mass in containment was calculated using pressure,

. temperature, and dewpoint data which was collected by the P-250 computers.

Air mass is calculated using the ideal gas law formula.

The formula is as follows:

M =

144 V (P-Pv)

R T

Where:

M=airmass,lbm P=total pressure,psia Pv=vapor pressure,psia R=53.35 ft-lbf/lbm R (for air)

T=average containment temperature,deg R V=containment free volume,l.8xE6 cu FT After the mass is calculated, the results are correlated as a function of time by using a least-squares-curve fit of the form:

Where:

M=At+B M=estimated mass A=least squares slope -

dM/dT B=least squares y - intercept -

Mo 4.3

The slope (A) and y-intercept (B) are used to calculate the leak

• • ,*rate.

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

Leak rate is expressed as the fraction of mass lost per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> out of containment:

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

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

The units for this value are

i.n wt%/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).

6.0 TYPE BAND C LEAKAGE TESTS.1 summarizes the Type Band C tests that have been performed since the 1983 refueling.

Included in these Tables are the As-Found,As-Left leakages for each penetration and a description of repairs if they were performed.

The Type C test method which was used prior to May 1985 was the downstream method.

At that time though, it was identified that the test results were not conservative.

Subsequent Type C testing was performed using the makeup method where it was feasible.

The total As-Found Type Band C leakage value during the 1986 refueling was 1221.19 SCFH which is above the maximum leakage of.6La (180 SCFH) as specified in 10CFR50, Appendix J, Section III.B.3.(a).

The corrective action taken to reduce the Type Band C leakage below.6La was to repair/replace valves which had leakages above the maximum allowable leakages as specified in the Type C test procedure.

Those penetrations which were repaired are listed in Attachment 6.1.

Included in the repairs that were performed during the outage was the replacement of the containment sump valves(TV-DA-lOOA and TV-DA-lOOB) with a design that is more suitable for its

• duty.

Its anticipated that the problems that were encountered previously with this penetration have been eliminated.

Following these repairs, the final As-Left Type Band C leakage was 78.437 SCFH which is below the.6La value of 180 SCFH.

A major part of the As-Left leakage can be attributed to Penetration 28 (HCV-1200's).

Due to the piping arrangement which makes identification of a faulty valve difficult and the valves location, a final As-Left value which is higher than the maximum allowable value in the Type c test procedure was accepted.

The basis for the acceptance of this leakage was that with the outside trip valve taken into account, the maximum leakage that could pass through this penetration is o SCFH.

6.1

To possibly alleviate problems with this penetration in the future, a study has been initiated to determine the feasibility of installing a trip valve downstream of the HCV-1200's and inside containment wall, thereby replacing the 1200's as the inside containment isolation valve.

If the results from this feasibility study are favorable, the project would be turned into a design change which would then be completed at some future outage..2 contains results of an As-Found Type A test analysis as requested by the NRC.

ATTACHMENT 6.2 1986 "AS-FOUND" LI.RT LEAKAGE

SUMMARY

During the 1986 Surry Power station Unit 1 refueling outage,certain containment isolation valves were repaired and/or replaced following the As-Found Type C tests.

The total leakage savings from these repairs or replacements was added to the Type A test results to determine the "AS-FOUND" condition of the containment.

Each penetration was evaluated using the following criteria:

1)

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

2)

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

3)

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

4)

• rf the post-repair minimum leakage is greater than pre-repair minimum pathway leakage, a leakage savings of zero is assigned to the penetration.

5)

6)

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

The net leakage savings (wt%/day) is added to the final Type A test results.

SUMMARY

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.

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

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

Reference Surry UFSAR Section 6.2.3.10, External Recirculation Loop Leakage.

2)

An earlier test of this penetration recorded a leakage of greater than 300 SCFH.

A retest was performed following a verification of the test valve lineup and the flowing of water through the line.

A minimum pathway leakage of 35 SCFH was recorded during the retest.

This retest was performed following the closing of both penetration valves (TV-DA-lOOA and B) in the normal manner, and without any external adjustments or repairs to the valves.

Therefore, 35 SCFH is being listed as the "pre-repair" leakage.

The basis for assigning this "pre-repair" leakage is discussed below.

These valves, and the corresponding valves on Unit 2, have been Type C tested at each cold shutdown since 1983.

When high leakage has been found, it has generally occurred during refueling outages, rather than during shorter maintenance outages.

This can be attributed to the extensive containment decontamination efforts which are now routinely performed at the start of each refueling outage prior to Type C testing.

These efforts have the effect of depositing additional debris in the containment sump, potentially leading to deposition of debris on the valve seat and the resulting failure of the valve to close completely.

These valves had been previously tested on 1/27/86 (TV-DA-lOOA) and 2/2/86 (TV-DA-lOOB) with leakages of 0.6 and 3.6

SCFH, respectively.

Thus it is likely that the high leakage seen at the start of the 1986 refueling outage can be attributed to debris from the decontamination effort, rather than being indication of actual containment condition prior to shutdown.

This is further supported by the significant reduction in leakage *following a flush of the valves.

Both valves were replaced during the outage with an improved design that should provide more suitable for this application.

This replacement was scheduled as a result of continuing leakage problems with these valves in previous outages.

Therefore, suitable corrective action has been taken to address the as-found condition of this penetration.

3)

This line is from the low head safety injection pump header and is used to supply the loops.

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

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