1.0 - ABSTRACT This report provides the details of the Byron Unit Two Preoperational Containment Integrated Leakage Rate Test (ILRT) performed on July 2 - July 18 of 1986. The_ test was performed in accordance with 10CFR50 - Appendix J, ANSI N45.4-1972 and the Byron Station Final Safety Analysis Report (FSAR).

The report includes information about 8 phases of the Byron Unit 2 Containment Leakage Rata Test Program which are defined as follows:

Phase 1 - Unit 2 Structural Integrity Test (SIT)

Phase 2 - Type B & C Local Leakage Rate Testing Phase 3 - ILRT Plant Equipment Lineup Phase Reduced Pressure ILRT Phase 5 - Full Pressure ILRT Phase 6 - Full Pressure Supplemental ILRT Phase.7 - Post ILRT Restoration Phase 8 - Type B and C Retesting Phase 2 testing took place in February - July of 1986. A brief discussion of the Phase 2 Local Leakage Rate Test Methodology and a summary of the leakage rates can be found in section 9. Phase 3 started on July 2 and Phase 8 concluded on August 7, 1986.

Phase 8 was necessary because a number of penetrations were blocked or sealed during the ILRT.. Their leakage rates were obtained subsequent to the ILRT and added to the Overall Integrated Leakage Rate determined for Unit 2 Containment.

2.2 Acc:pttnca Criteria for tha Typa B & C Tsats.

2. 2. l _ Acceptance Criteria #1 stated that the combined leakage rate, including the measurement error for all penetrations and valves 6 , subject to Type B & C tests shall be less than 0.60 L a at a minimum pressure of aP . For Byron Unit 2 containment L ais equal to 0.1 weight percent per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of tHe containment free air mass pressurized to Pa (44 4 Psig). Therefore 0.60 La is equal to 0.060%/ day or 277.76 SCFH.

The combined leakage rate including the measurement error for all performed Type B & C tests including retests is 126 1 1 SCFH. This. measured combined leakage rate of 127 SCFH falls below the acceptance' criteria limit of 277.76 SCFH.

2.2.2 Acceptance Criteria #2 for Containment Air Locks, stated that the Equipment Door Airlock and the Emergency Personnel Airlock shall each have a leakage rate of less than or equal to

0.05 Laat a minimum pressure of Pa (44.4 psig), where 0.05 La = 23.15 SCFH.

Two 4-bolt, blind flanged test ports are included on each airlock. One of these test ports on each lock was used as the' pressurization path. The individual leakage rate for the 4-bolt, blind flange removed during pressurization must be added to the respective airlock's leakage rate. 'However, each individual test ports' blind flange was found to have a leakage rate of 0.4 SCFH. The leakage rates for the Equipment Door Integral Personnel Lock and the Emergency Personnel Lock are as

.follows:

Equip. Door Integral Personnel Lock 1.8 i .053 SCFH

+ Blind Flange #1 0.4 i .053 SCFH l 2.2 1 075 SCFH Emerg. Personnel Lock 0.4 .053 SCFH

+ Blind Flange #1 0.4 + .053 SCFH 0.8 i .075 SCFH The leakage rates for the Equipment Door and Emergency Personnel Airlock, 2.2 i .075 SCFH and 0.8 1 075 SCFH, respectively, fall below the acceptance criteria limit of 23.15 SCFH.

3.0 - TEST PREPARATIONS-3.l' Type A Test Procedure a . The Unit 2 Preoperational Containment ILRT was performed in accordance with Byron Startup Manual, Revision 26 and Preoperational Test Procedure 2.58.61, Revision 2. During the performance of the test 10 Test Change Requests (TCR's) were written to change the 2.58.61 procedure. The majority of the TCR's were of a minor nature.

The ILRT~ procedure (2.58.61, Rev. 2) was written to comply with Appendix J of 10CFR50 and ANSI N45.4-1972. Although much of the methodology employed was that of ANSI 56.8 - 1981, Containment System Leakage Testing Requirements.

3.2 Type A Test Instrumentation Attachment 10.1 (ILRT Sensor Placement) shows the physical locations of the temperature (RTD or T) and humidity (DEW or D) sensors within the Containment. -RTD's and DEW cells located below the 426' level and above the containment basement floor at 377' were placed in one of two subvolumes. Either Inside the Missile. Barrier (IMB) or Outside the Missile Barrier (OMB) at the location indicated at the bottom of Attachment 10.1.

' Twenty-Five RTD's, ten Dew Cells and two absolute pressure gauges connected to a Volumetrics Dual Multiplexor Scanner and Data Acquisition System (DAS) were the main instrumentation used in the Byron Unit 2 ILRT. Additional instrumentation used included an ambient pressure transducer, ambient temperature RTD, and a flowmeter used to measure the superimposed leakage of the supplemental verification test.

Attachment 10.2. contains specifications for the aforementioned equipment including values for accuracy, repeatability, sensitivity and resolution for RTD, Dew Cell and pressure sensors. The quality and quantity of sensors chosen were such that the Instrument Selection Guide (ISG)* value would still be less than 0.25 La for a test duration of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> assuming failure of several RTD's or Dew Cells and one pressure sensor. x_

• ISG is defined in ANSI 56.8 - 1981.

Attichment 10.3 dipicts ths gsnsral arrangim:nt ralttiva to thm c:ntsinment _ wall cf cantoro, Multiplexor Sctnnar End tha Data Acquisition System (also known as the Integrated Leakage Rate Monitoring System). The two quartz bourdon tube absolute

. . pressure gauges were physically located outside containment within the DAS console. They were connected to Containment by a short run of poly-flo tubing. The flowmeter, also located near-the DAS console, was connected to containment by an independent run of poly-flo tubing. All electrical interconnection between the Multiplexor Scanner and the DAS was made through permanent Electrical Penetration E-13.

l 3.3 Type A Test Data Processing Leakage rate data was acquired by the DAS every 15 minutes.

This included Time, Julian Date, RTD Temperatures, Dew Cell Temperatures and Absolute Pressure sensor readings. The data was sent electronically to the Prime Computer through a RS232 format as shown in Attachment 10.4. The Prime Computer placed the incoming data into a permanent file from which it drew one data set at a time to compute the leakage rate. From the Prime Computer User Terminal the-data was reviewed for completeness -

and accuracy and then entered into the leakage rate program.

Leakage rates, raw data and calculation summaries could be printed as desired for review and later permanent storage. The multicolor plotting of leakage rates and other data on both hard copy (H.P. Plotter) and the RAMTEK CRT was available to facilitate trending parameters such as containment leakage rate, dry air pressure, vapor pressure and containment _ average temperature.

3.4 Type A Test Subvolume Determination The containment was divided into 5 discrete subvolumes.

Subvolume demarkation, size and weighting factors are indicated on Attachment 10.1. Subvolume calculations are shown for subvolumes 1, 2 and 3. Subvolumes 4 and 5 were arrived at by totalling subcompartment volumes used in the LOCA nodal analyses by Sargent and Lundy (plant architect-engineer). Subvolume 4 is defined as the annulus between the outermost containment wall and the Missile barrier below the 426' level. Subvolume 5 is the volume inside the Missile Barrier below the 426' level, not including the reactor cavity.

Two dew cell sensors were distributed to each subvolume so that loss of any one sensor would.not leave a subvolume uncovered.

RTD sensors were placed so that each sensor had a weighting factor of 3-5% and loss of any one sensor would not result in an RTD weighting factor of greater than 10% for any single sensor.

F~ 3 3.5- ILET P1rnt Equipment Lintup The valve and equipment lineups were detailed and specific, i.e.

component-by component with individual signoffs. This ensured

• * - containment integrity conditions as close as possible to those which would exist af ter a design basis Loss of Coolant Accident (LOCA). It also assured penetrations were properly drained and vented.

3.6 Structural Integrity Test The Structural Integrity Test (SIT) of Unit 2 containment preceded the Integrated Leakage Rate Test by approximately one year During the SIT the containment was pressurized to 57.5

-psig or 115% of its design pressure of 50 psig. A post-SIT.and another pre-ILRT inspection of' accessible interior and exterior containment surfaces indicated no significant deterioration of the containment structure.

3.7 Type A Test Pressurization One 7000 CFM and two 1800 CFM electrical " oil free" air compressors were used to pressurize containment.

The compressors were located outside on the west side of the Puel Handling Building. Pressurization was accomplished through a six inch header pipe which penetrates containment at penetration P-4. (See Attachment 10.5 for a general arrangement).

4.0 - TEST METHODOLOGY 4,.1 Reduced Pressure ILRT During this 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> test, pressure, temperature, and humidity data were taken to determine the statistically averaged containment leakage rate Ltm (weight percent /24 hours). The test was conducted at a nominal pressure of Pt (24 psig),

above the required minimum of 22.2 psig (0.5 P a). Reactor Containment Fan Coolers were not operated during this test. The purpose was to obtain data which can be compared to the Full Pressure ILRT data and future Reduced Pressure ILRT results.

4.2 Full Pressure ILRT During this 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> test, pressure, temperature, and humidity data were taken to determine the statistically averaged containment leakage rate Lam (weight percent /24 hours). The test was conducted at a nominal pressure of 45 psig, above the required minimum of Pa (44.4 psig) the Design Basis Accident containment pressure. Reactor Containment Fan Coolers were not run during this test. The purpose of this test was to determine a 95*4 Upper Confidence Limit value of L am for a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period.

4.3 Temperature Stabilization Periods Prior to the start of each ILRT a Temperature Stabilization Period of a minimum duration of 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> was employed. The criterion for temperature stabilization was as follows:

The latest rate of change of the weighted average containment air temperature averaged over the last hour does not deviate by 4 more than 0.5 *F/hr from the average rate of change of the weighted average containment air temperature averaged over the.

last 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

4.4 Supplemental Verification Test Following the Full Pressure ILRT, a deliberate leak of known magnitude was superimposed on the existing containment leakage through a calibrated flowmeter. The superimposed leak was maintained between 0.75 La and 1.25 La (5.79 and 9.64 SCFM). s The duration of the test was defined as a minimum of 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and -

10 sets of data. The acceptance criterion for the test was as follows: The statistically averaged Composite Leakage Rate (Lc) is within 0.25 La (1.93 SCFM) of the sum of the statistically averaged Full Pressure ILRT leakage rate (Lam) and the average flowmeter induced leakage rate (L o).

(1079M/0123M)

4.5 Method ef L-*kaga Ratt Ditsemination The leakage rate is assumed to be constant during the testing period, ideally yielding a straight-line plot with a negative o . slope. However, sampling techniques and test conditions are not perfect; consequently, the measured values will deviate from the ideal straight-line situation.

A least squares fit statistical analysis was performed to determine a regression line for mass versus time after each set of data was acquired. The slope of this regression line was designated to be the statistically averaged leakage rate (Lam) for the Full Pressure ILRT.

Associated with the statistically averaged leak rate was the 95%

upper confidence limit leakage rate (Lucla). The calculation of this upper limit was based upon the standard deviations from the regression line and the one-sided T Distribution function.

An expanded discussion of the Least Squares Fit ~ Statistical techniques used can be found in Attachment 10.6.

8.0 Intsrpr2tetion cf Tsit Raults 8.1 Reduced Pressure Test The statistically averaged containment leakage rate Ltm (weight percent /24 hours) was 0.025%/ day after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and 97 data sets. The 95% Upper Confidence Limit of Ltm (Lucir) was 0.029%/ day. The certainty of these results is substantiated by the fact the statistically averaged containment leakage rate Ltm held relatively steady for the last 14 hours1.62037e-4 days <br />0.00389 hours <br />2.314815e-5 weeks <br />5.327e-6 months <br /> of data. The 95% Upper Confidence Limit value during this same period was steady er decreasing slightly.

8.2 Full Pressure Test The statistically averaged containment leakage rate Lam (weight percent /24 hours) was 0.0217%/ day after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and 97-data sets. The 95% Upper Confidence Limit of Lam (Lucla) was 0.0253%/ day. The addition of required Local leakage Rate values and comparison to acceptance criteria is done in section 2.1. The validity of the results~is demonstrated by observing the decreasing behavior of Lucla between 1200 and 2400 test time. During this 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> period Lucla decreased quite steadily from 0.0444 to the final value of 0.0253.

Containment dry air temperature, containment dry air pressure and containment dewcell temperature all trended downward. These are all effects of a cooling containment with no major heat source, i.e. the Reactor Containment Fan Coolers were off. The data of this test in c'mparison o to the Reduced Pressure test was slightly lower. This can be attributed to better seating of check valves at higher pressures.

8.3 Full Pressure Supplemental Test After 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, 0415 real time on July 16, 1986 the statistically avereaged composite leakage rate (Lc ) was verified within 0.25 La (1.93 9CFM) of the sum of the statistically averaged Full Pressure leakage rate L am and the average flowmeter induced leakage rate (L o). A detailed comparison to acceptance criteria may be found in section 2.1.

8.4 Summary The Reduced Pressure Test was completed in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> without any significant events. The Full Pressure Test was restarted twice due to leaking airlock shaft seals. In the first instance the outer door was closed to orovide additional normal isolation.

In the other airlock *he laaking seals were pumped full of silicon and were inclosed as post ILRT penalties. After the ILRT the vendor was consulted and a representative disassembled and inspected the seals. It was determined that'several years of static storage causes inconsistencies in seals. Also the seals were replaced with an upgraded type having a higher spring rate. The "As Left" test on the new seals demonstrated no-leakage.

r 8.0 Int rpestition cf Tcat R;ults 8.4 Summary (Continued)

'- - One of the two pressure sensors was sticking and was deleted from the Full Pressure Test. The other sensor however tracked smoothly and gave good test results. Also the prime computer entered one RTD data point incorrectly. Once the entry was corrected the Leak Rate calculation was consistent.

The confidence of the Containment Integrity was demonstrated by the fact that the Full Pressure Test leak rate was one third of

~

the'. acceptance criteria. -In addition the Instrument Selection Guide was less than the limit required. The results of the

~ Supplemental Induced Leak Rate Test were well within the acceptance criteria proving the accuracy of the test results.

'9.0 - TYPE B & C TEST RESULTS 9.1 Local leak rate methodology - Type B and C tests were conducted in accordance with Appendix J to 10CFR50 and ANSI N45.4-1972.

.- .. The test volume was pressurized and regulated with air or

,#  : nitrogen to nominally 45 psig*. The flowrate necessary to

. maintain the test volume at 45 psig was measured after a proper stabilization period. This value was used as the test volume leakage rate.

• Personnel lock door gaskets were pressurized to 10 psig.

10.6 Leasc Squares Fit' Statistical Technique

.In order to comply with the intent of ANSI /ANS-56.8-1981 and 10CFR50, Appendix J, it was necessary to perform a least squares fit of the ILRT data. The method for "Least L T uares" is a statistical procedure for finding the best fitting regression line for a set of measured data. The criterion for the best fitting line to a set of data points is that the sum of the squares of the deviations:of the observed points from the line must be a minimum. When this criterion is met, a unique best fitting line is obtained based or,all of the data points. The value of the leak rate based on the regression is called-the statistically averaged leak rate.

Based on this statistical process, the calculated sta .ical leak rate is cbtained from the equation W = At + B Where W = contained dry air mass at. time t B = calculated contained dry air mass at time t=0 A = calculated leak rate t = test duration f

The values of the constants A and B such that the regression line is best fitting to the IPCLRT data are:

A .= {N[(ti )(Wi - {({ti )([Wi }} = (({t i-t)(Wi-5)} {N[(ti )2 - (Et i)2} 2(t-t)2 i B = {Wi - Alti =([ti 2)({wi)-([t i)({wit i) - N N{(t)2-(lti)2 i

                                                                                                         ~

By definition, leakage out of the primary containment is considered positive. leakage; therefore, the statistically averaged leak rate in weight percent per day is given by: L3 = -2400 (A)/(B) (weight %/ day) (1079M/0123M)
