I. INTRODUCTION AND PURPOSE A periodic Type "A" Integrated Leakage Rate Test (ILRT) was successfully conducted on the primary containment structure of the Florida Power and Light's Turkey Point Nuclear Power Plant Unit No.

4 Pressurized Water Reactor.

This test was performed in accordance with the Plant's Technical Specifications, and the Code of Federal Regulations, Title 10, Part 50, Appendix J, titled: "Primary Reactor Containment Leakage Testing for Water Cooled Power Reactors".

This report describes the test method used, and presents the results of the test, including the Supplemental Test (also known as the Controlled Leakage Rate Test, or CLRT), used for verification.

Summaries of the types "B" and "C" Local Leakage Rate Tests (LLRT) performed since the last ILRT are also included.

Turkey Point Nuclear Plant Operating Procedures OP 13100.1, 13100.4 and 13404.1 provided necessary guidance during the performance of these Tests.,

I

II. TEST DISCUSSION A. Description of the Containment The containment structure completely encloses the reactor and reactor coolant system.

It is the last barrier between fission materials and the environment.

Containment pressure retention is achieved by concrete walls that are post tensioned by a steel tendon system.

Leakage prevention is achieved by a 0.25 inch steel liner on the xnside of the containment wall.

Under accident conditions, leakage out of containment is not expected to exceed a predetermined amount.

A periodic Leak Testing Proqram of the containment penetrations and structural xnspections help assure containment leakage will not exceed the expected amount.

Inside diameter

= 116 ft.

Inside height = 169 ft.

I Approximate free volume = 1,550,000 cubic feet Calculated peak accident pressure

= 49.9 psig Analyzed Leakage

= La = 0.25 4 Per day of air mass inside Containment at 49.9 psi.

Acceptance Criteria for the ILRT = 0.75

La

= 0.1875 4 Per day of air mass inside Containment at 49.9 psi.

During the performance of the ILRT, the containment penetrations and isolation valves were aligned per OP-13100.4 to simulate as closely as 'possible the post Accident Containment Configuration.

Adjustments to the test's results were made for any valve lineups not representative of post LOCA configuration, and for any level increases noted during the test for vessels located inside Containment.

B. Description of the ILRT Instrumentation The Containment Building was instrumented to permit leakage rate determination in accordance with the Code of Federal Regulations, Title 10, Part 50, Appendix J, "Primary Reactor Containment Leakage Testing for Water Cooled Power Reactors".

The ILRT instrumentation provided a sufficient quantity of sensors of each type to aqcommodate instrument failures during the test without je'opardizing acceptability of the test's results.

The instrumentation allowed leakage rate determination by the Mass Point Analysis.

This method calculates the actual mass 2

~

0 of d~ air within the Containment.

The leakage rate becomes the tame rate of change of the calculated air mass.

Air Mass (M) is calculated according to the Ideal Gas Law as follows:

M 144 * ((P Pv)*V)/R*T M = Containment Air Mass (Lbs)

P = Containment Total Absolute Pressure, Psia T = Containment Absolute Temperature, Deg R Pv= Containment Vapor Pressure, Psig, at Temp.

T.

V = Containment Net Free Volume, Ft R = Universal Gas Constant.

(Ft*Lbf/Lbm*Deg R)

(Pv and T are weighted average values.)

The primary measurement variables required for the calculation of Containment air mass are absolute pressure, relative humidity and temperature as a function of time.

During the Supplemental

Test, a controlled Containment bleed off flow is also a measured variable.

The average Containment absolute temperature is determined by measuring specific local temperatures thxoughout the Containment and applying a mass and volume weighted averaging technique.

The volume fraction for each temperature sensor is determined based upon geometrical calculations.

Average Containment water vapor pressure is determined by measuring specific local relative humidities throughout the Containment.

This is converted to local vapor pressure using local group temperatures, a steam table, and a mass and volume weighted averaging technique.

The volume fractions for the relative humidity sensors are determined in the same manner as for the temperature sensors.

Wherever possible, Temperature and Relative Humidity Sensors were placed adjacent to each other.

Twenty One (21) Platinum Resistance Temperature Detectors (RTDs) located throughout the Containment allowed measurement of the weighted average air temperature.

Figure 1A through 1E depict the location of the RTDs in the Containment.

Each RTD sensor has a calibrated resistance versus temperature curve accurate to less than +0.5'F.

The sensitivity and repeatability of each RTD sensor is less than +0.054 F.

2.

~Humid t Instrumentation Ten (10)

Phys-Chem Relative Humidity Detectors (RHDs) located throughout the Containment allow measurement of the weighted average Containment vapor pressure.

Figure 1A through 1E depicts the location of the RHDs in the Containment.

The RHDs connect to two, five,channel Humeter amplifiers located outside the Containment.

'The calibrated accuracy of the RHDs is +2.0 4

~Pressu e I strumentation Two direct read out, Texas Instruments precision pressure monitors measured Containment absolute pressure.

Figure 2

depicts the arrangement of the tubing connections between the monitors and the Containment.

Only one pressure monitor was used for leakage rate calculations, with the second monitor as back-up in the event of failure.

The monitors had a

repeatability of +0.002 Psia.

4. Flow Instrumentation A variable area float-type rotometer is used to superimpose a

leakage during the Supplemental Test.

Figure 5 depicts the pipinq configuration between the rotometer and the Contaanment.

The rotometer has a +1.04 accuracy, and a +0.54 repeatability.

Two other instruments were used during the Supplemental Test.

A local pressure

gauge, and a

PRTD were installed in the Containment vent pipzng, to allow for compensation in the event of substantial pressure or temperature deviation from the Rotometer's calibration point.

The PRTD was connected to a Fluke 8520A/PRTD located in the same area as the test computer.

Ambient atmospheric conditions were monitored during the course of the test.

Barometric pressure, temperature, wind speed and direction were obtained from Homestead Air Force Base Meteorological Facility. A summary of the information is contained in Appendix C.

6. Instrument Selection Guide ~ISG Calculation The Instrument Selection Guide (ISG) compiled the instrument sensitivity and resolution for each process variable and evaluates the total instrumentation system's ability to detect leakage in the range required.

The ISG for this test was calculated by the Computer Program used to compute the ILRT results.

The calculated ISG for the instrumentation operable during this test (21 temperature

sensors, 9 relative humidity sensors, and 1 pressure sensor) was 0.0054 4 per day, which was verified to be less than

.25 La as speczfied in ANSI 56.8.

C. Description of the Computer Program Florida Power and Light utilized software developed by Ebasco Plant Services Inc. for leakage rate calculations during the course of the test.

The Program is an interactive program written specifically for fast, easy utilization during all phases of the ILRT and Supplemental Test.

The program is written in a high level, compiled, structured language and

- operates on a MS-DOS personal microcomputer.

Besides providing extensive data verification routines, the program offers the flexibilityof calculating leakage rates and the 4

A given instrument may be deleted from the calculations if a sensor malfunctions.

The deletion of a given instrument is performed on all samples in the data base.

Volume fractions for the remaining instruments of that type are then recalculated based upon the placement and the amount of Containment volume sensed by these instruments.

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 is recorded on magnetic media to prevent loss during the test.

In addition, two hard copies of the data are also made throughout the test by a printer attached to the test

computer, and by the Datalogger's built in printer.

All data is stored on the computer system in use, with retrieval capability to any desired data base throughout the testing.

Ancillary portions of the computer program assist the user in determinatxon of temperature stabilzzation, determining the ILRT termination criteria, performing ISG calculations, and determination of acceptable Supplemental Test leakage verifications. It also allows the user to monitor instrument repeatability error, to aid in the identification of any malfunctioning sensors.

During the test, temperature, pressure and humidity data was automatically transmitted from the ILRT instrumentation system to the computer at approximately 20 minute intervals.

Figure 3 illustrates the connection between the ILRT instrumentation system and the computer analysis system.

D.

Containment Pressurization equipment.

The equipment used to pressurize the Containment is shown in Figure 4.

The eight oxl-free industrial diesel driven air compressors had a total nominal capacity of 11,100 SCFM.

The compressed air was processed by a water cooled after-cooler, a moisture separator and a refrigerant air dryer.

E.

Description of the Testing Sequence.

Preparations to pressurize the Containment for the conduct of the ILRT included internal and external inspections of the Containment structure; installation and checkout of the temporary ILRT instrumentation system; Types "B" and "C" Local Leakage Rate Testing of the Containment penetrations; alignment of the necessary valves and breakers for test conditions; the installation and checkout of the temporary Containment pressurization facilities; removal of plant instrumentatxon that could be damaged by the test pressure; venting of any permanently installed tanks that could be damaged by the test pressure; and the removal or depressuri-zation of any pressurized gas sources inside Containment.

II tt

Containment pressurization started at 17:40 Hrs, 10-17-91, and was secured at 05:03 Hrs on 10-18-91 at a peak Containment pressure of 67.583 psia.

The average pressurization rate throughout this time period was approximately 4.4 psi per hour.

Appendix Al illustrates the testing sequence.

The temperature stabilization phase began at 05:04 Hrs on 10-18-91. External leakage surveys were initiated with no significant leakage found.

The Mass Point temperature stabilization criteria was met at 10:04 Hrs on 10-18-91, and ILRT measurements were initiated.

Appendix A2 contains the temperature stabilization results.

During the test, Containment vapor pressure and relative humidzty were found to be higher than expected.

This was attributed to a leak discovered, after the test, in a valve associated with the water cooled after-cooler.

This higher than expected humidity caused fluctuations in containment pressure which in turn caused substantial deviations in calculated containment air mass.

These deviations statistically would not support a short duration test as described in Bechtel Corporation's Topical Report BN-TOP-l, Revision 1, "Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants."

At 10:04 Hrs, 10-19-91, all acceptance 'criteria for a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months test was met, with Mass Point Upper Confidence Limit of 0.0540 4

The fitted Mass Point leakage rate was 0.0480 4 per day.

These values are well below the test acceptance criteria of 0.18754 per day.

Appendix A3 contains the ILRT data and test results.

At 10:08 Hrs on 10-19-91, the Supplemental Test was started, and subsequently stopped due to condensation noted in the rotometer.

The rotometer was disassembled for cleaning /

drying, and the vent piping was insulated to allow the piping and Containment temperatures to equalize.

At 13:30 Hrs, 10-19-91, with the vent piping temperature stabilized, the Supplemental Test was re-started with an imposed leakage rate of 14 scfm.

The fitted Supplemental Test leakage rate was 0.336 4 per day.

Appendix A4 contains the Supplemental Test data, results and acceptance criteria.

The Supplemental Test was completed at 17:35 Hrs on 10-19-91 with all acceptance criteria satisfied.

Data analyses showed that RH Sensor 410 exceeded 100% relative humidity during the Supplemental Test.

RH Sensor 510 was deleted, the remaining volume fractions recalculated, and all of the data for the ILRT and Supplemental Test re-analyzed.

The other relative Humidity or temperature sensors in this group did not exhibit any unusual behavior and followed the expected process trend.

The Data and the test results remained satisfactory for the recalculated values.

Containment de-pressurization was initiated at 18:04 Hrs on 10-19-91, and was completed at 02:45 Hrs on 10-20-91.

Average de-pressurization rate was 6.75 psi per hour.

Figure 6 illustrates the de-pressurization piping configuration.

Containment entry for post-test inspection was at 03:30 Hrs, 10-20-91.

The post-test inspection detected no major anomalies or damage to the equipment or structures of the Containment.

1990-1991 LOCAL LEAKAGE RATE SUMKARY ANALYSIS The as found ILRT, by analysis, is used to show what the results of performing an ILRT at the beginning of the outage would have

been, before any repairs or adjustments were made to the penetrations.

The as found minimum pathway leakage, the repairs performed and the as left minimum pathway leakage for each boundary or penetration were reviewed.

The net leakage contribution for each penetration was determined utilizing the following criteria:

1.. A leakage rate add-on equivalent to the repair improvement is assigned to each penetration.

2.

The net equivalent leakage assigned to the penetration is the lowest leakage of the valve grouping (e.g. simulates minimum pathway leakage).

3. If a repair was not performed on a containment isolation valve, and a reduction in leakage is noted between the as found and as left test, no penalty is required to be assessed.

4.

No leakage credit is taken if the as left leakage rate is higher than the as found leakage rate.

Only those penetrations where repairs were made to the isolation valves are included in this attachment.

5. For series isolation valves tested together (i.e. combination tests),

the penetration net equivalent leakage is half the difference between the as found and the as left leakage rates when both valves are repaired at the same time.. If only one valve is repaired or both valves are repaired at different times, subsequent analysis of test results may be performed to determine the penalty to be assessed.

6.

When the summation of the leakage equivalent and the leakage measured during a successful Type A test is greater than L, the penetration(s) with excessive leakage(s) will be analyzed Co determine the cause of the failure and/or corrective action taken to prevent recurrence.

7. All measured leakage rate values are in units of cubic centimeters per minute (CCM) at 50 psig.

Based on the above criteria and the values tabulated on the next

page, the net equivalent leakage of 0.036 percent/day, when added to the results of this ILRT (0.057 percent/day mass point UCL plus corrections),

indicates that the as found ILRT test result, determined by analysis (0.093 percent/day) is below the plant's maximum allowable leakage rate of 0.25 percent/day.
