I. INTRODUCTION AND SUNMARY A periodic Type,"A" Integrated Leakage Rate Test (ILRT) was successfully conducted on the primary containment structure of the Florida Power 5 Light Company St. Lucie Plant Unit No. 1 Pressurized Water Reactor. This test was performed at full pressure in accordance with the facility Technical S peci f ications.

This ILRT test was performed using the "Absolute Nethod" of testing in accordance with the Code of Federal Regulations, Title 18, Part 58 Appendix J, 'Primary Reactor Containment. Leakage Testing for Water-Cooled Power Reactors," in accordance with ANSI N45.4 1972, American National Standard, "Leakage Rate Testing of Containment Structures for Nuclear Reactors," and the methodology and calculational requirements of Topical Report BN-TOP-1, Revision 1, "Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants." The ILRT was performed at a pressure in excess of the calculated peak containment internal pressure related to the design basis accident as specified in the Final Safety Analysis Report (FSAR) and the Technical Speci f ications.

This report describes and presents the results of the periodic Type "A" leakage rate testing, including the supplemental test method utilized for verification. In addition, Florida Power 5 Light Company performs types "B" and "C" testing in accordance with the requirements of 18CFR58, Appendix J, and the Technical Specifications. The results of types "B" and "C" testing performed since the last ILRT are provided in this report ~

The resulting reported "as-found" Type "A" containment leakage at 48 2 pslg

is 8.195 percent of the contained mass per'ay. This value includes the difference between the as-found and as-lef t, minimum pathway Types "B" and "C" local leakage measurements as required by the NRC I&E Information Notice 85-71. The resulting reported "as-lef t" Type "A" containment leakage at 48.2 psig is 8.181 percent of the contained mass per day. The acceptance criteria for this test as contained in the facility Technical Specifications is that leakage cannot exceed 8.375 percent of the contained V

air mass per day at 39.6 psig for either the "as-found" or "as-lef t" case.

II. TEST DISCUSSION A. Descri tion of the Containment The containment vessel completely encloses the entire reactor and reactor coolant system to ensure no leakage of radioactive materials to the environment in the unlikely event of a loss of coolant accident.

The containment system design incorporates a free-standing containment vessel surrounded by a low-leakage concrete shield building. A four-foot annular space is provided between the outer wall of the containment vessel and the inner wall of the shield building to allow filtration of containment vessel leakage during accident conditions to minimize of f-site doses ~

The free-standing containment vessel is a two-inch thick right circular cylinder with a one-inch thick hemispherical dome and two-inch thick el lip-soidal bottom. The overal 1 vessel dimensions are 148-foot diameter by 232-foot high. The vessel wall thickness is increased to a minimum of four inches adjacent to all penetrations and openings. The vessel is fabricated of ASIDE-SA 5i6 Grade 7$ ful ly killed pressure vessel quality steel plate.

The net free volume of the containment vessel is 2.5 x 1$ 6 cubic feet.

The containment vessel structure includes one personnel airlock, one emergency escape lock, one fuel transfer tube, one equipment maintenance hatch'nd one seal-welded construction hatch. All process piping and electrical penetrations are welded directly to the containment vessel nozzles with the exception of the main steam, main feed water, and fuel transfer tube penetrations. These penetrations are provided with testable II multiple ply expansion be}lows to allow for thermal growth or building differential motion.

I I

The containment vessel is designed and constructed in accordance with the requirements for Class NC vessels contained in Section II I of the ASNE Code (1971 Edition) . The containment vessel is code stamped for a design internal containment pressure of 44 psig at a temperature of 264 F. The containment vessel and al 1 penetrations are designed to limit leakage to less than 8.5 percent by weight of the contained air per day at the above design conditions. The calculated peak accident pressure for the design basis accident for the St. Lucie Plant No. 1 is 39.6 psig, in accordance with Technical Specification 3.6. 1.2.a. 1.

B. Descri tion of ILRT Instrumentation The containment system was equipped with instrumentation to permit leakage rate determination by the "absolute method." Utilizing this method, the actual mass of dry air within the containment is calculated.

The leakage rate becomes the time rate of change of this value. The mass of air (9) is calculated according to the Perfect Gas Law as follows:

0= (P-Pv) V RT where: P Containment Total Absolute Pressure Pv Containment Water Vapor Pressure (Average)

V Containment Net Free Volume R Gas Constant T Containment Absolute Temperature (Average)

The primary measurement variables required are containment absolute pressure, containment relative humidity, and containment temperature as a function of time. During the supplementary verification test, containment bleed-off flow is also recorded.

Average containment absolute temperature is determined by measuring discrete local temperatures throughout the containment and applying a mass and volume weighted averaging technique.

The volume fraction for each sensor is determined based upon solid geometrical calculations:

where: T Containment Absolute Temper ature (Average)

T.1 Local Temperature for sensor i Vf; Volume Fraction for sensor i Average containment water vapor pressure is determined by measuring discrete local relative humidities throughout the containment, converting these to local vapor pressures using local group temperatures and applying a mass and volume weighted averaging technique. The volume fractions for

temperature. The location of the temperature detectors in the containment is depicted in Figure 1. Each RTD sensor was supplied with a calibrated resistance versus temperature curve accurate to +8.5 F. The sensitivity and repeatability of each RTD sensor is less than +8.8126 F.

C The signal conditioning circuit and readout for the RTD sensors was a Fluke 2288B data logger o'perating in a constant, cur rent mode. The operating parameters for the RTD constant current card are accurate to

+8.16 F and have a resolution of +8.81 F.

Each RTD was in-situ calibration checked after installation to verify correct operation. The data logger operating as a total loop with an RTD in the circuit has a repeatability of +8 81 F'nd a resolution of

~

+8 81 oF

2. Humidi t 'Instrumentation Ten Resistance Humidi ty Detectors (RHDs were located throughout the I

containment to al low measurement of the weighted average containment vapor pressure. The location of the RHDs in the containment is depicted in Figure 2. The calibrated accuracy of the RHDs is +2.5 percent RH, the repeatability of the RHDs is +8. 1 percent RH, and the sensitivity of the RHDs is +8.81 percent RH.

The readout dev'ice used for the RHDs was a Fluke 2288B data logger operating in a voltage measurement mode.

Each RHD was in situ calibration checked af ter instal lation to verify correct operation. The repeatability of the loop is +8.1 percent RH while the resolution of the device is +8.81 percent RH.

3. Pressure In s trumen ta tion Two Volumetric precision pressure moni tors were used to determine containment absolute pressure. The arrangement of tubing connections 5

between the monitors and the containment is sho~n in Figure 3. Ei ther monitor could be used as the primary pressure sensor for leakage rate calculations with the remaining sensor considered as a backup. The calibrated accuracy of the monitor is +8.815 percent of reading. The sensitivity, repeatability, and resolution of the monitor is +$ .881 psi.

Binary Coded Decimal <BCD) output from both monitors was connected to the Fluke 2288B data logger.

4. Flow Instrumentation A variable area float-type rotameter was used to superimpose leakage during the supplementary CLRT. The piping connection between the rotameter and the containment is shown in Figure 3. The accuracy, repeatability, and sensitivity for the rotameter in units of SCFN and converted to equivalent leakage values is given below:

Peak Pressure Rotameter, Equi va 1 en t SCFN L~a~acae Accuracy +8.28 +8.8831 %/day Repeatability +8.85 +8.8888 %/day Sensitivity '+8. 85 +8.8888 //day

5. Instrument Selection Guide ( ISG) Calculation The Instrument Selection Guide is a'ethod of compiling the instrumen-tation sensitivity and resolution for each .process measurement variable used during the ILRT and evaluating the total instrumentation system's ability to detect leakage rates in the range required. The I SG formula is described in American National Standard ANSI/ANS 56.8-1987. Although the ISG is a very conservative measure of sensitivity, the general industry practice for this test has been to require sensitivity at least four times better than the containment allowable leakage or ISG < $ .25La.

The calculated ISG for the instrumentation used for this test was 8 8883 ~

percent per'day, for an 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months test. The allowable value for this test is 8.25La or $ .125 percent per day, for an 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months test. The ISG calculation met all recommended criteria and demonstrated the ability of the ILRT instrumentation system to measure containment leakage with a sensitivity t

I I

exceeding that required by the appr opriate industry standards.

C. Containment Pressurization E ui ment The equipment used to pressurize the containment. is shown in Figure 4 ~

The thirteen oil-free industrial diesel-driven air compressors had a total nominal capacity of l2,988 SCFM. The compressed air was then routed to water-cooled af ter-coolers, moisture separators, and refrigerant air dryers. This equipment assured that clean and dry air was used to pressurize the containment.

D. Descri tion of the Com uter Pro ram The Ebasco ILRT computer program is an interactive program written specifically for fast, easy utilization during all phases of the ILRT and CLRT. The program is wri tten in a high-level, compiled, structured language and is operated on a portable NS-DOS personal computer. The program has been verified and meets all requirements of the Ebasco and Florida Power & Light Quality Assurance Programs.

As necessary, data entry and modifications are readily accomplished by the data acquisition team. In addition to extensive data verification routines, the program calculates, on demand, total time and mass point leak rates as wel 1 as the 95 percent Upper Conf idence Level for these leakage rate calculations. Calculations and methodology of the program are derived from American National Standard ANSI N45.4-1972 and Topical Report, BN-TOP-1, Revision l.

Input data may be deleted for a given instrument in the case of a sensor malfunction. The deletion of a given instrument is performed on all samples in the data base. Weighing factors, if applicable, are then recalculated for the remaining instrument sensors of that type (see section III.A).

Data evaluations are enhanced by the flexible display of either sensor variables or various computed values in tabular or graphical form on the computer screen or printer. Data are recorded on magnetic media to prevent

I I

I

loss during the testing. Al 1 data are stored on the computer system in use, with retrieval capability to any desired data base throughout the testing .

Ancillary portions of the program assist the user in determining temperature stabilization, determining the ILRT termination criteria, performing ISG calculations, performing in situ instrument loop performance calculations and determining acceptable superimposed CLRT leakage veri-f ication.

Temperature, pressure and humidity data are transmitted from the ILRT instrumentation system to the computer via an RS-252 link at 28 minute intervals (see Figure 5). Computer verification and checking routines supplement data verification by the data acquisition team. Modifications can be promptly made if errors are det'ected.

structure; installation and check out of the ILRT instrumentation; Types "B" and "C" Local Leakage Rate Tests; alignment of valves and breakers for test conditions; and the installation and check out of the temporary pressurization facilities. These preparations were completed on April 5, 1998.

Al 1 ILRT instrumentation was declared operable with performance within manufacturers'o)erances. Pressure sensor No. 1 was selected to be the primary pressure instrument, as it had exhibited better repeatability and stability during the in situ testing.

Three penetrations were required to be in service during the ILRT and were not lined up to simulate accident conditions; P-52D ( ILRT Pressure Sensing Line), P-52E ( ILRT Controlled Bleed-of f Line), and P-54 ( ILRT Pres-

I I

I

surization Line) . The three ILRT penetrations are used to conduct the test. The minimum pathway leakage for those penetrations, determined during Type "C" local testing, is added to the measured ILRT leakage to account for these penetrations being in service during the test.

Pressurization of the containment started at 8314 hours0.0962 days 2.309 hours 0.0137 weeks 0.00316 months on April 5, 1998. Figure 6 pictorially depicts the sequence of testing. The pressurization rate was maintained at 4 psi/hr. Early in the pressurization mode, the Assistant Nuclear Plant Supervisor (ANPS) requested that, the test be stopped due to PDIS-25-1B (Containment dP sensor) failing low, which caused FCV-25-8 ( Con t a inmen t Vacuum Breaker) to open on high vacuum. The fuses for FCV-25-8 were pulled, shutting the valve, and pressurization was restarted. Subsequent to completion of the ILRT the PDIS was repaired.

The target pressure of 55. 165 psia was achieved at 138S hours on 4/5/89.

This target pressure was 8.865 psi above the minimum test pressure to account for the expected pressure decrease due to temperature stabilization and to allow for some leakage margin during the test sequence. Data acquisition and analysis during the temperature stabilization phase began at 1318 hours0.0153 days 0.366 hours 0.00218 weeks 5.01499e-4 months at 28 minute intervals.

The containment temperature stabilization criteria was met at 1718 hours0.0199 days 0.477 hours 0.00284 weeks 6.53699e-4 months on April 5, 1998, af ter acquisition of four hours of data. During this period, the temperature and pressure decreases followed predictable trends, and the trend of vapor pressure was stable.

Six hours into the ILRT hold time, leakage had increased to greater than

.375 //day in magnitude. Two valves were found to be leaking) MV 87 2A MV-87-2B (Containment Sump Valves) . Both of these valves are in service and covered with water during the design basis accident. They are boundary valves for the ILRT (see sect. I II.C) . These valves were checked shut, MV-87-2A received 'wo turns and MV-87-2B received three turns. The ILRT hold time was restarted at 2318.

The 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months period of leakage measurements started at 2318 hours0.0268 days 0.644 hours 0.00383 weeks 8.81999e-4 months on April 5, 1998, and was successful ly terminated at 8718 hours0.101 days 2.422 hours 0.0144 weeks 0.00332 months on April 6, 1998, all other acceptance criteria contained in Bn-Top were met and the ILRT was shown to be successful. The data accumulated displayed the following leakage rates:

Simple BN-TOP-1 Leakage Rate = 8.8694 %/day Fitted BN-TOP-1 Leakage Rate = 8.$ 826 //day 95% Upper Confidence Level (UCL) = 8.1B18 //day Since leakage plot had-a negative skew ( tending to decrease) af ter 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months , the leakage rate was not extrapolated linearly to 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , using the last 28 data points. The acceptance criteria for this test is 8.75 La or 8.375 %/day.

To verify the results of the ILRT, a verification Controlled Leakage Rate Test (CLRT) was conducted. Using the variable area full-pressure rotameter, a superimposed flow of 19.0 SCFN was'dded to the leakage already present in the containment. This superimposed flow is equivalent to leakage of 8.299 percent per day. A one-hour stabilization period was allowed to lapse after addition of this leakage in accordance with the requirements of Topical Report BN-TOP-1. Data accumulation for the CLRT was started at 8818 hours0.102 days 2.449 hours 0.0146 weeks 0.00336 months on April 6, 1998 and the CLRT was conducted for a four-hour period. The measured CLRT leakage rates for this period were:

Simple BN-TOP-1 Leakage Rate = 8.3290 %/day Fitted BN-TOP-1 Leakage Rate = 8.3336 %/day The target CLRT leakage for this test was 8.382 +8.125 percent per day, or within the criteria as measured. The ILRT and CLRT were declared successful at 1218 hours0.0141 days 0.338 hours 0.00201 weeks 4.63449e-4 months on April 6, 1998.

At 1216 hours0.0141 days 0.338 hours 0.00201 weeks 4.62688e-4 months on April 6, 1998, depressurization of the containment was initiated at a rate of 6 psi/hr. Containment entry for post-test inspection purposes occurred when the containment pressure was approximately $ .5 psig at. 2$ $ $ hours on April 6, 199$ . The post-test V

III . ANALYSIS AND INTERPRETATION A. Instrumentation S stem Performance All of the forty temperature detectors performed as expected with no anomalous behavior detected by data trend analysis or by the Ebasco ILRT computer program error checking routines. The computer program also determines, the in situ temperature loop repeatability which consists of process measurement variations as wel l as sensor noise. The average in situ loop repeatability for the forty operating temperature sensors was 8.813 0 F. This performance compares well with the vendor-claimed temperature sensor loop repeatability, excluding process variations, as given in Section I I . 81.

Ten relative humidity sensors were installed in the containment for the ILRT. All operated as expected with no anomalous behavior detected by data trend analysis or by the ILRT computer program error checking r outines.

The average in situ loop repeatability for the relative humidity sensors was 8.1 percent RH. This performance compares well with the vendor-claimed humidity sensor loop repeatability, excluding process variations, as given in Section I I . B2.

11

I Two pressure sensors were installed for the ILRT, with one utilized for testing and one considered as a spare. Prior to containment pressurization, analysis demonstrated that pressure sensor 1 was more stable over an eight hour period than the other sensor. During the ILRT, the in situ pressure loop repeatability for both sensors was 8.881 psi ~

This performance compares well with the vendor-claimed pressure sensor loop repeatability, excluding process variations, given in Section II.B.3-The variable area rotameter performed as expected with no evidence of unstable reading, float sticking, or moisture in the float tube.

In summary, all of the ILRT test instrumentation performed in an adequate manner to al low dete'rmination of containment leakage rates to the sensi tivity required.

B. Tem erature Stabilization Phase Prior to pressurization of the containment, the atmosphere was very stable with an average temperature of 82.1 F and a maximum spread of'em-perature from the highest reading sensor to lowest reading sensor of 3-9 F. During pressurization, the heat of compression of the air occurs mainly at the top of the containment with colder pressurization air being added at the bottom. At the end of pressurization, the average temperature was 96.4 F with a maximum spread of temperature from the highest reading sensor to lowest reading sensor of 24.4 F.

The results of the four-hour temperature stabilization phase are presented in Appendix B.l. The acceptance criteria given in Topical Report BN-TOP-1, Revision 1, are described in Note 2 in that appendix. The data pr esented shows that a smooth and predictable temperature stabilization occurred. At the end of stabilization, the average temperature was BB-B F and the maximum spread of temper ature f rom the highest reading sensor to the lowest reading sensor was 13. 1 F. This demonstrates that the heat sinks of concrete and steel in the containment, were quickly r eturning the containment atmosphere to a stable condition.

12

I C. Leaka e Surve Phase Leakage in excess of .375 La was noted af ter the temperature stabi li-zation phase criteria'had been met. Leakage survey teams were dispatched to investigate the source of leakage. Leakage was found on penetrations 32 and 33 (Containment Sump Suction). Nhile checking the boundary valves shut it, was noted that NV-87-2A required two ful l turns and NV-87-2B required three full turns to be ful ly closed. These two isolation valves are not considered as potential leakage barriers in the Final Safety

'Analysis Report (FSAR) sec tions h. 2. 4. 2 and 6. 2. 4. 4 and thus are not subject to type C or Bypass leakage testing as they will be water covered in a loss of coolant accident and open during the recirculation phase of the transient. Any water leakage through these valves in the closed position wil 1 be returned to the containment. by the Safety Injection System pumps. No potential containment leakage or off-site dose is credible due to seat leakage of these valves in the closed position. Leakage rate measurements on the containment were restarted after the leakage survey phase using the total time leakage rate methods of Topical Report BN-TOP-1, Revision 1. As an additional diagnostic tool, mass point leakage rate measurements, as described in ANSI/ANS 56.8-1981, were conducted in parallel. The mass point leakage calculations are not sensitive to the starting point of the test and wil l detect changes in containment leakage more rapidly than the total time method.

D. Inte rated Leaka e Rate Phase Leakage measurements were started at 2318 hours0.0268 days 0.644 hours 0.00383 weeks 8.81999e-4 months on April 5, 1998. The total time BN-TQP-1 results for eight hours of leakage measurements are presented in Appendix B.3. A summary of the measur ed leakage af ter eight hours is:

BN-TQP-1 Total Time Simple Leakage Rate 8.869 %/day Fitted Leakage Rate 8.883 %/day Upper Conf idence Level 8. 181 %/day The higher Upper Conf idence Level of the BN-TOP-1 measurements is due

to the nature of performing regression analysis on simple leakage rates instead of regression analysis on masses and the more conservative statistics utilized by BN-TOP-I.

As all acceptance criteria for a Reduced Duration BN-TOP-l ILRT were met at. eight hours as presen ted in Appendix B. 2, the ILRT was dec ared 1 acceptable.. Appendix A presents the corrections to the measured ILRT leakage rates for local leakage rate measurements for both the "as-found" and "as-left" cases.

E. Uerification of Controlled Leaka e Rate Phase Subsequent to the acceptance of the ILRT results, a superimposed leakage equivalent to 8.2'P9 percent per day was added to the existing containment leakage using the variable area rotameter. A one-hour stabilization period was allowed to lapse after addition of this leakage in accordance with the requirements of Topical Report BN-TOP-i.

Leakage measurements were initiated to verify the r esults of the ILRT.

The minimum duration for the Controlled Leakage Rate Phase was determined to be four hours in accordance with Topical Report BN-TOP-I. As presented in Appendix B.3, the leakage measur ements met the acceptance criteria for the veri f ication phase.

TABULATION OF "AS-FOUND" AND "AS-LEFT" ILRT RESULTS A. Correction of ILRT Results for "AS -FOUND" Case In accordance with NRC 18cE Information Notice 85-71, additions are required to the ILRT results due to repairs and/or adjustments made due to Local Leakage rate testing during an outage in which an ILRT is conducted.

The corrections include only repairs or adjustments made to containment leakage boundaries which were made prior to the ILRT. These corrections are the difference between the pre-repair.and post-repair leakages calculated in the minimum pathway case and corrected for uncertainties in the measurements.

LOCAL LEAKAGE RATE PROBLEMS SINCE LAST ILRT On February 18, 1988 Containment Radiation Monitor isolation valve FCV-26-1 was found to have a leakage rate of approximately 188 scfm. This value was in excess of the plant' Technical Specif ication limit of 8.27 La (245,153 sccm) . This was reported on Licensee Event Report ¹335-88-$ 82. The valve was repaired and the as-left leakage was 458 sccm. The outside valve on this penetration was 1188 sccm, thus the as-found as well as the minimum pathway leakage for this penetration was 1188 sccm. 81
