1.0 Introduction As prescribed in Browns Ferry Nuclear Plant unit 3 technical specification 4.7.A.2, the leakage of air from the boundary forming the reactor building primary containment is limited to 2 percent of containment air mass per day at the calculated peak accident pressure P

In conformance with Title 10, Code of Federal Regulations, Part 50, Appendix J, Browns Ferry technical specifications require that reactor building integrated leak rate tests be performed as part of the startup and the surveillance programs to demonstrate continuing leak-tight integrity.

An inservice reactor building containment integrated leak rate test

{CILRT) was successfully completed on Hrowns Ferry unit 3 by personnel of the Tennessee Valley Authority on November 25, 1979.

This test was conducted in accordance with a plant approved surveillance instruction, BP SI 4.7.A.2, which is on file at the plant site.

This surveillance instruction implements the requirements of Browns Ferry unit 3 technical specifications and Appendix J to 10 CFR 50.

The American National Standard for Containment Testing, ANSI N45.4-1972 and the proposed American Nuclear Society Standard for Containment

Testing, N-274

, provided guidance for the procedure implemented by the surveillance instruction.

Browns Ferry unit 3 is a boiling-water reactor employing a steel pressure suppression containment and rated 3,293 megawatts thermal.

The Final Safety Analysis Report defines the calculated peak accident pressure P

to be 49.6 psig.

The reactor building containment is divided into two ma]or compartments the drywell, enclosing the reactor and the

'I I

i

forced recirculation system, and a pxessure suppression pool chamber.

These two compartments are connected by blowdown pipes that terminate below the suppression chamber pool level.

Vacuum breakers are provided to ensure that the suppression chamber is never pressurized with respect to the drywell.

For the performance of this CILRT, these vacuum breakers were mechanically locked open to ensure pressure equalization between the drywell and the suppression chamber.

This report outlines the obgectives, principal events, and special equipment used and provides analysis of the test results for the CILRT completed on November 25 on Browns Ferry unit 3'.

2.0 Test Purpose and Results A.

Test Purpose The objective of the inservice CILRT performed on Browns Fexry unit 3 was threefold.

The principal objective was to demonstrate the leak-tight integrity of the reactor building containment for return to power operation.

For Browns Ferry unit 3, the leak-tight integxity is defined by technical specification 4.7.A.2 and the preoperational CILRT to be that the leakage:of air from containment not exceed 0.04437 percentage per hour (1.06488 percent per day) of containment air mass at a reduced pressure of P. /2.

The second ob)ective of this CILRT was to determine if any degradation of the structure forming the containment may have occurred since the performance of the preoperational CILRT.

A pretest inspection of the containment surface was performed to identify the presence of any gross deformities of the structure.

I

The final objective was to evaluate several significant changes of the equipment used to conduct the test.

These changes included additional compressed air capacity for containment pressurization and the revision of all test instrumentation to provide for the computer-directed automatic acquisition and reduction of test data.

Previously used for the unit 2 CILRT conducted in June

1978, these changes were implemented by the Tennessee Valley Authority to determine whether test accuracy could be improved substantially while reducing the time required to conduct future tests.

B.

Test Results The leakage rate measured in the 24-hour CILRT was 0.00709 percentage of containment air mass per hour (0.17014 percentage per day) at a reduced pressuxe of 25 psig.

The observed 95-percent upper confidence limit for this measured leak rate was 0.00718 percentage of containment air mass per hour (0.17236 percentage per day).

This measured leak rate renresents 15.98 percent of that'..al'lowed under t

technical specification 4.7.A.2.

k After the completion of the CILRT, a", supplemental forced leakage verification test was conducted to check the results of the CILRT.

A Forced leak of D.S6936 percentage of containment mass per day was imnosed on the containment.

Ttce leak rate measuxed for the 4-1/3-hour vertification test was 0.95442 percentage of containment air mass per day.

Agreement as prescribed by Appendix J between the CILRT and the verification test was -0.0544LT which is wel:l..

within the +0.250 L required by technical specification.

4.0 Measurements and Calculations A.

Test Equipment The test equipment used for the CILRT at Browns Ferry unit 3 was acquired for its improved accuracy over previous CILRT equipment.

Table 1 lists the equipment,

range, accuracy, and repeatability.

All test equipment was calibrated by'he Tennessee Valley Authority

V P'

Central Laboratories or other facilities with standards traceable to the National Bureau of Standards.

After the installation of all special test equipment inside containment, each sensor was checked for functional operation.

Upon test completion and depressurization, each sensor was again checked to ensure adherence to calibration.

B.

Sensor Location Table 2 lists the final volumetric weighting factor for each temperature and dewpoint sensor based on a 2-compartment model.

Figures l through 7 identify sensor locations.

The pressure sensors were divided up so that two sensors measured drywell oressure through pressure transmitter line PT 64-50 and two sensors measured torus pressure through pressure transmitter line PT 64-20.

A fifth pressure sensor measured the barametric pressure at the test station.

C.

Computer-Based Acquisition and Data Reduction System Containment oarameter measurements for the Browns Ferry un t 3

CILRT were made and collected by a microprocessor-based data acquisition system.

This raw data was automatically presented to a portable minicomputer system for correction to calibration curves and reduction to containment leak rate.

Statistical confidence levels of the calculated results were reported auto-matically to the test director as the data was acquired.

Figure 8

depicts the functional relationship of the acquisition and data analysis system.

All calculations performed by the minicomputer system were in conformance with the procedures outlined in ANS N-274'draft).

Source listings for all computer programs are on file with the Division of Nuclear Power, Controls and Test Branch, in Chattanooga, Tennessee.

Table 3 identifies the principal function of each computer program.

D.

Instrument Rejection The data presented in this report reflects the test results following the deletion of certain sensors due to equipment failure.

The following table lists the sensor deleted by location, as shown in figures 1 through 7, and the reason for the sensor being deleted.

Sensor Location RTD-4 and RTD-6 RTD-23 Discussion Due to damage to signal cables following the CILRT, a calibration check in place could not be accomplished.

Initial calibration check was out of tolerance and the sensor was deleted at the beginning HE-1, HE-7 and HE-8 of the CILRT.

Instrument response was erratic compared with known conditions in the initial stages of I

the CILRT.

The HE-7 sensor was found inoperative Pressure in post test calibration.

The HE-8 sensor was found to have a loose wire in the post test calibration.

It was suspected that the dewcell solution was disturbed on the HE-1 sensor.

During the CILRT, pressure sensor number 1

Sensor No.

1 indicated low with a continuous rising value

throughout the test.

This erratic behavior was duplicated during post test calibration at the TVA Central Laboratories.

5.0 Data Analysis The previous sections of this report have described the general test conduct, calculation methods, and test equipment.

In this section the events and problems that influenced the test results are discussed and used to dew conclusions on the performance of the Browns Ferry unit 3 CILRT.

A.

Discussion of Craphical Results Figure 9 is a graph of the calculated containment air mass for the CILRT.

The graph axes are absolute air mass versus test time.

The slope of the least squares fit line to this data is the reported leak rate.

Figure 10 is a graph of the calculated containment air mass leak rate versus test time for the CILRT.

Figure 11 is a graph of containment average pressure versus test time, and figure 12 is a graph of containment average temperature versus test time.

An abrupt change in test conditions is shown in the graphs approximately 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> after the start of the CILRT.

(The test was started at approximately 1230 hours0.0142 days <br />0.342 hours <br />0.00203 weeks <br />4.68015e-4 months <br /> on November 23.)

The official test log recorded at 8:30 p.m.

on November 23 that a level change in the reactor pressure vessel was noted.

The shift engineer was contacted and he stated that the loss of a 500-KVA feeder line and a slow transfer to a backup had caused the loss of shutdown cooling and the reactor water temperature had increased accordingly.

This was reflected by the unstable containment leak rate at this point in the test and resulted in an extended test period to a,}.;low restahilization.

The graphs indicated that stabilized containment conditions and a stabilized leak rate were being approached when the effect of the loss of shutdown cooling and reinitiation of shutdown cooling created unstable conditions.

After an extended stabilization period, the containment mass 3eak rate approached a stabilized level closely approximating that observed after 6 to 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> (approximately the time of loss of shutdown cooling).

8.

Instrumentation Performance The instrumentation error analysis of appendix A indicates that the instrumentation used in the unit 3 CILRT was extremely accurate in the determination of the containment leak rate, abd it far surpassed the recommendation of N27A that the measuring system be capable of detecting 0.25 L.

Using the ISG,.guidelines as t

developed in appendix A, the CILRT duration could be reduced to I

8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> without imoact if stable conditions were present.

The loss of 3 RTD's, 3 dewcells, and 1 pressure sensor had no significant effect on the ISG due to the number of sensors employed initially (see paragraph 4.0.D).

1. 0 Introd uc tion Appendix J to 10CFR50 and Browns Ferry technical specifications require that the total leakage.from all penetrations subject to types B and C

testing be less than 0.60 La for return to power operations. Technical specification 4.7.A.2.i requires that the leakage through each main-steam isolation valve be less than 11.5 SCFH, in addition to the total leakage requirement. This appendix presents a summary of all local leak rate testing performed on Browns Ferry unit 3 since the completion of the preoperational CILRT. An analysis and interpretation of conditions contributing to the failure of meeting either the acceptance criteria of technical specifications or Sections III.A.5(b), III.B.3, and III.C.3 of Appendix J are included. 2.0 Summary Tables B-l, B-2, B-4, and B-5 lists the type B and type C testing performed on Browns Ferry unit 3 since the preoperational tests. Testing was performed in accordance with plant approved surveillance instruc-tions BF SI 4.7.A.2.g-l, BF SI 4.7.A.2.g-2, and BF SI 4.7.A.2.g-3 which are on file at the plant site. Table B-3 summarizes cycle 1 test results and Table B-6 summarizes cycle 2 test results. Four out of eight of the main steam isolation valves required rework to meet the 11.5 SCFH limit during cycle 1 testing. And five out of eight of the main steam isolation valves required rework to meet the 11.5 SCFH limit during cycle 2 testing. The total as left leakage was 180.2821 SCFH during cycle 1 testing and 106.3427 SCFH during cycle 2

testing. Both as left totals were well below the 60 percent La limit of 655.9216 SCFH. The total leakage of isolation valves that terminate below the suppression chamber water level was 1.5043 CFH for cycle 1 tests and 1.2972 CFH for cycle 2 tests. The total leakage for isolation valves that are located in closed loop seismic class 1 lines that are water sealed was 2.9566 CFH for cycle 1 tests and 7.3845 CFH for cycle 2 tests. 3.0 Analysis of Data To facilitate testing and prevent the draining of large volumes of contaminated water to the drain sumps, TVA proposed testing certain non-water sealed valves with water and converting the measured leakage to an equivalent air leakage (reference J. E. Gillelands letter to James P. O'Reilly, Office of Inspection and Enforcement, dated August 14, 1978). This was accomplished during cycle 1 testing on those valves noted in Table B-l. It was felt that the total leak rate penalty for using the water to air conversion was more severe than TVA should accept, therefore a technical specification change was submitted requiring all valves that are not water sealed during a DBA be tested with air. The cycle 2 testing reflects this change. The total type B and C leakages prior to the return to power was significantly below the 60 percent L limit even though the total leakage is derived from the largest leak of the two isolation valves for type C leak tests.

The main steam isolation valves are tested with air applied between the inboard and outboard isolation valves. This tends to lift the inboard main steam isolaion valves off the seat. Three out of four outboard main steam isolation valves were less than 11.5 SCFH during initial cycle 1 tests and two out of four outboard main steam isoltion valves were less than 11.5 SCFfl during initial cycle 2 tests. Ilow-

ever, one out of four inboard main steam isolation valves was less than 11.5 SCFH during cycle 1 and during cycle 2 tests.

It is believed the direction the test pressure is applied to the inboard main steam isolation valves contributes to the increased failure
