Page 4 1,0 (-INTRODUCTION This report contains the summary. technical analysis of the Reactor Containment 1 Building Integrated Leak Rate Test (C1LRT) conducted on Sequoyah Nuclear Plant (SQN) Unit 2 April 27-29.

As prescribed in SON Unit 2 Technical Specification 4.6.1.2, the leakage of air from the boundary forming the reactor primary Containment Building is limited to 0.2$ percent by weight of the containment air mess per day at a pressure of 12.0 psig.. This test.was conducted in accordance with the requirements"of Title 10, Code of Federal Regulations, Part 50, Appendix'J, which is implemented by SON Jurveillance Instructions (SI) 2-SI-SLT-088-156.0; the American National Standard for Containment Testing, ANSI 45.4-1972; the proposed American Nuclear Society for Containment Testing, ANS 56.8; and the procedure outlined in Bechtel's

. Topical Report, " Testing. Criteria'for Integrated Leakage Rate Testing of Primary _ Containment Structure for Nuclear Power Plants" (BN-TOP-1, Revision 1),--provided guidance for the procedure implemented by the SI.

SON Unit 2 is a 3,411-megawatt thermal,cpressurized-water reactor employing an ice condenser pressure suppression containment.

The Final Safety Analysis Report-defines the celculated peak accident pressure, Pa, to-be_12.0 psig. The Reactor Building containment is divided into four

~ major compartments for the CILRT analysis--the lower ice condenser

compartment which houses the energy-absorbing lae beds, the upper ice condenser compartment which. encloses the support equipment for the ice condenser system, _the lower compartment which contains the reactor'and

~

the main piping systems, and the upper compartment which can accommodate Ltne displaced air mass from the other compartments in the unlikely event of-a loss-of-coolant accident (LOCA).

These four compartments are 1904C

=. _ __ _

, _.~.

Fage 5 connected by means of blowout panels located between the lower compartment and lower ice condenser compartment and between the uppet compartment and upper ice condenser compartment.

In the eve et of a LOCA, steam flows from the lower compartment through the ice condenser compartments and into upper containment. The upper compartment is sealed from the lower compartment to ensure that any steam released in an accident will be forced through energy-absorbing ice beds.

For the performance of the CILRT, the lower and upper compartments were not 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 April 29, 1992, on SON Unit 2.

A summary of local leak rate tests (LLRTs) conducted since the previous CILRT are included in Appendix L.

In addition, results of an incident investigation conducted to determine the root cause and appropriate recurrence controls for excess leakage through a locally tested leak, age path (penetration X-47A) are included in Appendix M.

SUMMARY

The SON Unit 2 CILRT was conducted from April 27 to 29, 1992, in conjunction with the Cycle 5 refueling outage.

The CILRT was successfully completed in 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months and 10 minutes and included 56 data samples.

The calculated total time leak rate (TTLR) for the CILRT was 0.06161 percent per day (%/ day).

The associated reportable "as found" l

95 percent upper confidence limit (UCL), which includes Type B and C l

-accounted for_by the CILRT computer system, was 0.42122 %/ day.

,The."as left" 95 percent UCL value of 0.15154 %/ day includes Type B and C leakage for testable. penetrations in service during the CILRT and

- compensation. for water. level changes not accounted for by the CILRT computt.r system.

The calculated "as found" mass leak rate (MLR) for the CILRT was 04739 %/ day.- The associated reportable "as found" 95 percent UCL was

'O.32822.%/ day,~and the reportable "as left" 95 percent UCL was

.O.05854'%/ day.

These values reflect the adjustment provisions as described for the TTLR.

'3.0 TEST P1fRPOSE AND RESULTS 3.1 ' Test Purpose The objective of the inservice CILRT was to demonstrate the continuing' leak tight integrity of the Unit 2 Reactor Building containment for-return to power operations, For! Unit'2, the lesk tight integrity is defined in Technical (Specification 4.6.1.'2-to be the leakage of air from containment is I

Pressurisation to 12.,69373 psig was completed at 0647 on April 28, J

4 1492, and the pressurisation header was isolated from the air comp Asors.

l The criteria for temperature stabilisation phase was met at 1114 on April 28, 1992 (see Appendix A for stabilization graphs and tabular

'o data).

Although the pressurization rate had be**

limited to

-minimize destabilising-the containment parameters and the rate of chang' ' in containment temperature met the BN-TOP-1 requirement, the data was undtable beyond the initial four hours.

f The pressurization rate had been controlled to ach,leve test pressure in about 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months . 'This was done to limit gross changes in f

o containment vapor _ pressure and temperature which was experienced on 7

the pres

. Unit 1 CILRT when full test pressure was reached after only 6 1/i nours using maximum flow.

However, there was a temperature inversion with-tu.1 crease in humidity in the 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months imm6diately preceding pressurization:for-the Unit 2 CILRT.

This i

inversion _was partially countered by limiting the pressurization rate; however, the stabilization-phase had to be extended so that

.the totax stabilisation time was 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and 10 minutes, i

The increase-in stabilization time allowed humidity and temperature to' settle sufilciently so that equilibrium data could be realized.

pressure-in compartments 1 and 2.

The initial values (during the l

6 hour6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and 10 minute stabilisation phase) were on the order of l

double the magnitude experienced for stable test conditions. There was also a temperature fluctuation in. compartment 1 at the start of 7

tae temperature stabilisation phase which served to destabilize conditions, but it is not certain whether the temperature

(

fluctuation was due to stabilisation or another influencing factor.

When the test-related parameters became relatively stable (i.e.,

linear trend) the TTLR assumed an expected proffic.

At approximately four hours into the C1LRT, several test equipment Y

hardware failures occurred.

Initially, a Monsor pressure gauge measuring lower ice condenser pressure spontaneously began to oscillate (this type of pressure gauge uses a null and feedback system to track pressure changes). This incident was fellowed by the redundant pressure ga,ge in the lower ice compartment overranging with a subsequent error displayed on the data logger.

Ultimately, the overranging instrument was " failed" in the data base which-removed all readings from-it in the calculations.

During the recovery.from the initial error condition, another alarm came in on

?the data logger display panel.- In this case, the RS 232 serial port to the primary com' uter had failed, thus data was being collected l -

c f

and processed only on the backup computer system.- No further failures occurred and the CILRT, as well as the verification test, a

was completed with the backup computer and with one Mensor pressure O

gauge' removed from the' data base.

The associated figures 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 pressute gauge during the '.est while continuing to accurately monitor containment pressure.

5.4 Rtpits.t_Dn1141ng._CrnLainetat_lics111 An ice condenser pressure suppression containment presents special problems not normally encountered in the leak testing of dry a

containment structures. The pressure suppression design feature requires the Reactor Building containment to be divided into distinct compartments, where vastly different temparatures and vapor pressures may exist. While each compartment is vented to the containment atmosphere during the performance of the CILRT, the direct circulation of air is limited.

1904C

Page 14 l

i Since an ice condenser containment typically exhibits a 40'F tenperature differential between the ice compartments and others, it la necessary to compensate by compartmentalization so the leak i

rate is accurately measured.

For SQN linit 2 CILRT, a 4. compartment containment model was used to measure the leak rate.

The free air mass is calculated individually for each compartment, and containment leak rate is calculated from the sum of the j

compartmental masses.

Each sensor within a compartment is volume i

weighted for the_ calculation of compartment average temperature, vapor pressure, and' absolute pressure.

6.0 AMMJSis OF TEST DATA L

The previous sections of this report have discussed the general test conduct and test equipment.

In this section, events and problems that J

influenced the test results are discussed and are used to forrulate conclusions on the performance of the SQN Unit 2 Cycle 5 CILRT.

6.1 Ingtrument Check The instrument complement for SON Unit 2 was 49 RTDs (temperature instruments), 13 Dewcells (measure vapor pressure), 1 flow meter

.I (for verification test),-and 9 Mensor quartz pressure gauges (8 containment pressure and one atmospheric prossure gauge).

J e

1904C

. _ _ _. -. ~, ~ -

pago 15 l

Prior to the start of the test, 1 RTD was removed from the data base.

The mode of failure was the extension cable frem the signal conditioner to the sensor. This RTD had to be removed from the i

data base due to the unavailability of a replacement extension

. cable of sufficient length to reach the required RTD location.

During the test, one Monsor pressure gauge monitoring lower ice condenser pressure was also removed from the data base. The instrumentation analysis conducted in accordance with ANSI 50.8 1987 demonstrated that the measurement system provided excellent capability regarding determining the leak rate without those instruments included the data base.

6.2 Discussions of Graphical and Tabular Results of the CILET Upon conpletion of pressurization, the relevant parameters began to achieve equilibrium conditions. The vapor pressure in the two largest compartments, upper compartment and lower compartment comprising 87 percent of the total volunie, was higher by a f actor of approximately 1.8 over that which is normally expected when near equilibrium conditions exist. The condition may be an inherent tendency of an ice condenser containment following pressurizing to elevated pressures but this condition was also intensified by the temperature and humidity inversion which occurred prior to the test (i.e., the temperature dropped approximately 15*F and it rained 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months before the test and remained cloudy throughout pressurization). The ice condenser compartments are not as i

1904C l

page 16 susceptible to changes in vapor pressure and temperature due to pressurization since the temperature is controlled and is near the frost point most of the time.

In addition, the upper compartment temperature early in the stabilization phase (first 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ) did not follow the other three compartment temperature patterns. There was a sharp decrease then an increase with a delta in temperature of approximately 1*F followed by a transition to a linear trend in temperature pattern.

With the exception of extending the stabilization period and reverting to the backup system for data acquisitlon processing the CILRT progresse_ satisfectorily to completion in accordance with

(

the requirements of BH-TOP-1, Revision 1.

6.3 Discussion of Agreement (Verification Test)

Verification flow was allowed to stabilize far over an hour prior to the official start of the verification test.

The stabilization of verification flow was performed in accordance with the requirements of BH-TOP-1, Revision 1, and the subscraent verification test was completed without significant trends or events which affected test results.

6.4 Discussion of "As Found" Leak Rate Exceeding Technical Specifications Applications of " leakage savings" per IE Notice 85-71 resulted in a technical failure of the CILRT before the test was performed.

A single penetration (X-47A), in the ice condenser glycol system was 1904C

l page 17-j i

responsible for this failure. During performances of LLRTs on i

Isolation valves FCV 61-191 (the outboard containment barrior), and FCV 61-192 and its associated thermal relief check valve CV 61-533 (the inboard containment barrier), it was discovered that both the i

Inboard and outboard air operated diaphragm valves (FCV 61-191, FCV 61-192) talled to fully closo. The resulting minimum path leak rato'of 211.1943 SCFH was greator than the acceptanco critoria of

]

160.75 SCFH for the CILRT. An Incident Investigation, II No. 5-92-30, was conducted to.dotermine the cause and extent of the problem, the. history of those and similar valves,;and appropriato recurrence control. Results of IT Ho. S-92-30 are included in Appendix M.

As can be seen from this investigation, these type valves have an excellent leakage history on both units at SQN.

Additionally, stroke timing is performed quarterly to ensure their operability. Valvos FCV 61-191 and FCV 61-192 were stroke testod

{

satisfactorily as recently as February _22, 1992, which was only three weeks prior to the refueling outage (LLRTs were performed.

April 1, 1992).

Howevo,r, since valvo-stem lubrication frequency may have contributed-to tho failure of those-particular.valvos-to closo, the proventive maintenance instructions for the Unit 1_and.

i Unit 2 glycol containment isolation valves have boen revised to I

include monthly lubrication of the valve stems.

7.0, CONCLUSIONS The SQN UnitT2_ Cycle.5 CILRT'was conducted with a total "as'found" leak I

-rato of 0.42122 %/ day (TTLR) ~ and a total "as-left" leak rate of 0.10154 %/ day (TTLR).- The "as found" failure was due to-the LLkT failure of penetration-X-47A which had a'leakago savings of

'O.23404 %/ day.

The MLR in comparison was 0.32822 %/ day for'the total "ns'found" and 0.05854 \\/ day for the total "as left."

1904C

i Page 18 l

t l

The TTLR "as found" was 0.18718 %/ day excluding the "3eakage savings" from glycol penetration X.47A.

This value is less than 75 percent La.

[

dhts on leakage through penetration X-47A and penetrations Historica) ernploying like valves demonstr ates that f ailure of these isolation valves to close was a random occurrence.

Corrective action has been Implemented to reduce the chance of a recurrence. The SON Ur.it 2 containment demonstrated its leak-tight integrity during the CILRT.

Corrective actions taken on the two previous CILkT failures on this unit have been demonstrated to be effective and are unrelated to the leakage.

i experienced through penetration X-47A during performance of the LLRTs.

Although this test represents the third failure nn this unit, the causes are unrelated and have been fully addressed.

Performlng future CILRTs 1

-on an accelerated schedule would serve no technical purpose.

We I

therefore propose to continue tho' norinal test schedule for SQN Unit 2.

The next regularly scheduled performance is during the Cycle 7 refueling

(

outage currently scheduled for April 1995.

PE0HIEN On April 1, 1992 ouring the performance of Surveillance Instruction (SI) 158.1, local leak rate testing of containment isolation valves, the valves in path X-47A were found to have excessive as-tound leakage rates. 2-FCV-61-191 (outboard) nad a leakage rate of S26.6563 Standard Cubic Feet per flou r ( SCFil) and 2-FCV-61-192/2-CV-61-533 (inboard) had a leakage rate of 211.1943 SCFil. The minimum path leakage may Le used for Labulating the as-tound leakages when figuring the margin of improvement that must be added on to the final containment integrated leak rate as required by I.E. Bulletin 85-71. Since the acceptance criteria for SI-156, the Containment Integrated Leak Rate Test (CILRT), is less than 168.75 SCfd, the minimum path leakage of X-47A (211.1943 SC Flf ) caused the leakage to exceed the allowable thus failing the CII.RT befvre it was actually performed. II. }[O_OT_Eb us e f ) Personnel statements irdicate that a smali nut (approximately 1/4 *) was found under the valve utem nut on 2-FCV-61-191 that prevented the valve from going fully closed. '1 h i s a ppea r s to have come troc unrelated work in the immediute vicinity of the valve. There was not a subsequent test on the valvt atter the nut was ren.oved and prior to maintenance. 4 Maintenance was perfotmed using Work order (WG) 92-08413-00, as planned for Work Request ( WR ) C04 6 t$ 15. The only maintenance performed was the lubrication of the stem on each of the FCVs. It cannot to ascertained ~ if the leakage on 2-FCV-61-191 was cauued unialy by the smail nut or if the stem was also a problem. In any case the-stem was lubricated. Both FCVu were utroked a number of times and were then retested and had 0.0 leakage tateu. Uased on these observations, there are two posuible causes; the first would be foreign material that prevented

t. 5 e out bo srd value from clouing alI the way and the second would be hardware related (e.g.

valve utems uticking). III.
