INTRODUCTION
-s This report presents data, analysis, and conclusions pertaining to the Calvert Clif fs Nuclear Power Plant, Unit 2, Integrated Leakage Rate Test (ILRT) performed in November, 1985. The Integrated Leakage Rate Test (Type A) is performed periodically to demonstrate that the combined leakage through the reactor containment and those systems penetrating the containment does not exceed the allowable leakage rate specified in the Plant Technical Specifications.
The successful periodic Type A and supplemental verification tests were performed according to the requirements of the Calvert Clif fs Nuclear Pbwer Plant, Unit 2, Technical Specifications and 10CFR50, Appendix J.
The Calvert Clif fs Type A test method is the Absolute Method described in ANSI N45.4-1972, " Leakage Rate Testing of Containment Structures for Nuclear Reactors" and ANSI /ANS 56.8-1981,
" Containment System Leakage Testing Requirements." The leakage rate was calculated using formulas f rom the above ANSI Standards and BN-TOP-1, Rev. 1, " Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants."
Type A and verification test durations were according to the criteria of EN-TOP-1.
A 95% upper confidence level was calculated for leakage rate data as required by Reference 6.
This is to ensure a 95% probability that the calculated leakage rate value is within the acceptance limits. All
('53 calculations were done with Bechtel's ILRT computer program described K/
in Appendix A.
The temperature and pressure history and the containment air mass variations were plotted by the computer program and are contained in Appendix E.
II.
TEST SYNOPSIS Valve line-ups were conducted on all systems to establish post-accident conditions except for shutdown cooling, demineralized water, and three penetrations necessary to conduct the ILRT. The inspection of the containment's accessible interior and exterior surf aces was conducted prior to pressurization.
No evidence of structural deterioration was noted which would have af fected containment integrity or leak tightness.
Containment pressurization commenced at 12: 25 a.m., November 23, 1985.
The containment coolers and fans were stopped at 12:00 noon. Te st prensure of 50.1 psig was reached at 1:00 p.m., November 23, 1985, and the pressurization line was vented. The temperature stabiliza-tion criteria were satisfied suring the four hours f rom 12:00 midnight to 4:00 a.m.

Collection of data' to determine the integrated leakage rate commenced
( ])
- at 4:00 a.m., November 24, 1985, and was completed at 12:30 p.m.
The verification flow test was initiated at 12:30 p.m., November 24, 1985.
l The verification flow test was completed satisfactorily and depressur-ization of the containment commenced at 11:15 p.m., November 24, 1985.
i Af ter the containment was completely 'depressurized, a containment i
entry was made. Determination was made that no measurable water level changes requiring corrections to the measured leakage rate had occurred during the test. A summary of test phases follows:

Temper-ature sensor 17 f ailed when pressurization began at 12:25 a.m.,
November 23. The sensor was destroyed by pressurization air flow turbule nc e.
Sensor 17 volume fraction was reassigned equally among sensors 10,15, and 16, all below elevation 45 f eet. Temperature sensors 2 and 3 decreased about 3*F at 1:00 a.m., November 24, which
, ()
was inconsistent with adjacent sensors.
Sensors 2 and 3 were declared inoperable and volume f ractions reassigned to sensors 1, 4, 7,.8, 9,
11, and 13, all in the open volume above elevation 69 feet. Temper-ature sensor 6 consistently indicated temperatures 5 to 8'F higher than adjacent sensors.
Sensor 6'was declared inoperable and its volume f raction reassigned to sensor 14, also at elevation 50 feet and outside the steam generator cavities. Dewpoint sensors 1, 2, 3, and 6 j
were not operational until 12:00 midnight November 24 The stabil-ization period was longer than the minimum-required because the dew cell power was inadvertently turned off. When the power was turned on, a dramatic jump in calculated air mass was observed, shown clearly in the airmass plot of Appendix E.
The reassigned volume fractions were used to calculate the containment dry air mass during the entire j
teat.
Plots of sensors are in Appendix I.

ANALYSIS AND INTERPRETATION O
The Integrated Leakage Rate Test resialts at the upper 9'5% confidence level are 0.60%/ day (Mass Point analysis) and 0.104%/ day (Total Time analysis). The local leakage rate for penetrations not in postLOCA lineup is 0.001%/ day.
The sums of the ILRT upper 95% confidence level and LLRT leakage rates, 0.061%/ day (Mass Point analysis) and 0.105%/ day (Total Time analysis), satisfy the acceptance criterion that the. sum must be less than 0.75 La = 0.150%/ day.
Local Leakage Rate Test, repair, and adjustments of containment isolation valves were performed prior to the ILRT. The minimum pathway leakage improvement due to repairs and adjustments is 140,591.24 seem or 0.081%/ day. The as found containment leakage rat e s, the sum of the minimum pathway leakage improvement and ILRT upper 95% confidence levels, 0.185%/ day (Mass Point analysis) and 0.186%/ day (Total Time analyste), satisfy the as found acceptance
- criterion. that the sum must be less than La = 0.200%/ day.

APPENDIX A DESCRIPTION OF BECHTEL ILRT COMPUTER PROGRAM A.
Program and Report Description 1.
The Bechtel ILRT computer program is used to determi.4e the inte-grated leakage rate of a nuclear primary containment structure.
The program is used to compute leakage rate based on input values of time, free air volume, containment atmosphere total pressure, drybulb temperature, and dewpoint temperature (water vapor pressure).
Leakage rate is computed using the Absolute Method as defined in ANSI /ANS 56.8-1981, " Containment System Leakage Testing Requirements" and BN-TOP-1, Rev 1, " Testing Criteria for Integrated Leakage Race Testing of Primary Containment Structures for Nuclear Power Plants".
The program is designed to allow the user to evaluate containment leakage race test results at the jobsite during containment leakage testing. Current leakage rate values may be obtained at any time during the testing period using one of two computational methods, yieldfng three different report printouts.
2.
In the first printout, the Total Time Report, leakage rate is coa-puted from initial values of free air volume, containment atmosphere fs x i
(
)
drybulb temperature and partial pressure of dry air, the latest values of the same parameters, and elapsed time.
These individually computed leakage races are statistically averaged using linear re-gression by the method of least squares.
The Total Time Method is the computational technique upon which the short duration test criteria of BN-TOP-1, Rev 1, " Testing. Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plant," are based.
3.
The second printout is the Mass Point Report and is based on the Mass Point Analysis Technique described in ANSI /ANS 56.8-L981,
" Containment System Leakage Testing Requirements." The mass of dry air in the containment is computed at each data point (ti=e) using the Equation of State, from current values of containment atmosphere drybulb temperature and partial pressure of dry air.
Contained mass is " plotted" versus time and a regression line is fit to the data using the method of least squares.
Leakage rate is determined from the statistically derived slope and intercept of the regression line.
4 The third printout, the Trend Report, is a summary of leakage rate values based on Total time and Mass Point computations presented i
as a function of number of data points and elapsed ti=e (test dura-t io n ). The Trend Report provides all leakage rate values required for comparision to the acceptance criteria of BN-TOP-1 for conduct of a short duration test.
5.
The program is written in a high level language and is designed for use on a micro-computer with direct data input from the data acquisition system.
Brief descriptions of program use, formulae A-1
g
(
used for leakage rate computations, and program logic are provided in the following paragraphs.
B.
Explanation of Program 1.
The Bechtel ILRT computer program is written, for use by experi-i enced ILRT personnel, to determine containment integrated leakage rates based on the Absolute Method described in ANSI /ANS 56.8-1981 and SN-TOP-1.
2.
Information loaded into the program prior to or at the start of the test:
a.
Number of containment atmosphere drybulb temperature sensors, dewpoint temperature (water vapor pressure) sensors and pressure gages to be used in leakage rate computations for the specific test b.
Volume f ractions assigned to each of the above sensors c.
Calibration data for above sensors d.
Test title e.
Test pressure g.
Maximum allowable leakage race at test pressure 3.
Data received from the data acquistion system during the test, and used to compute leakage rates:
a.
Time and date b.
Containment atmosphere drybulb temperatures c.
Containment atmosphere pressure (s) d.
Containment atmosphere dewpoint temperatures e.
Containment free air volume.
4.
After all data at a given time are received, a Summary of Measured Data report (refer to " Program Logic," Paragraph D, " Data" option command) is printed.
5.
If drybulb and dewpoint temperature sensors should fail during the i
test, the data from the sensor (s) are not used. The volume frac-tions for the remaining sensors are recomputed and reloaded into the program for use in ensuing Leakage rate c'omputations.

Program Logic 1.
The Bechtel ILRT computer program logic flow is controlled by a set '
of user options.
The user options and a brief description of their associated function are presented below.
OPTION COMMAND FUNCTION Af ter starting the program execution, the user either enters the name of the file containing previously entered data or initializes a new data file.
DATA Enables user to enter raw data. When the system requests values of time, volume, temperature, pressure and vapor pressure, the user enters the appropriate-data. After completing the data entry, a summary is printed out.
The user then verifies that the data were entered correctly.
If errors are detected, the user will then be given the opportunity to correct the erro rs.
Af ter the user verifies that the data were entered correctly, a Corrected Data Summary.Repo t of time, data, average temperature, partial pressure of dry air, and water vapor pressure is printed.

COMPUTER REPORT AND DATA PRINTOUT MASS POINT REPORT The Mass Point Report presents leakage rate data (wt%/ day) as deter-eined by the Mass Point Method. The " Calculated Leakage Race" is the value determined from the regression analysis. The " Containment Air Mass" values are the masses of dry air in the containment (Iba).
These air masses, determined from the Equation of State, are used in the regression analysis.
TOTAL TIME REPORT f
The Total Time Report presents data leakage rate (wt%/ day) as deter-
\\
mined by the Total Time Method. The " Calculated Leakage Rate" is the value determined from the regression analysis.
The " Measured Leakage Rates" are the leakage rate values determined using Total Time calcu-lat ions. These values of leakage rate are used in the regression analysis.
TREND REPORT l
The Trend Report presents leakage rates as determined by the Mass Point and Total Time methods in percent of the initial contained mass of dry air per day (wt%/ day), versus elapsed time (hours) and number of' data points.
SUMMARY
DATA REPORT The Summary Data report presents the actual data used to calculate leakage rates by the various methods described in the " Computer Program" section of this report. The six column headings are TINE, DATE, TEMP, PRESSURE, VPRS, and VOLUME and cantain data defined as follows:
1.
TIME:
Time in 24-hour notations (hours and minutes).
2.
DATE:
Calendar date (month and day).
3.
TEMP:
Containment weighted-average drybulb temperature in absolute units, degrees Rankine (*R).
A-9
l)T 4
PRESSURE:
Partial pressure of the dry air component of the con-
\\--
tainment accosphere in absolute units (psia).
5.
VPRS:
Partial pressure of water vapor of the containment atmosphere in absolute units (psia).
6.
VOLUME:
Containment free air volume (cu. ft.).
F.
SUMMARY
OF MEASURED DATA AND
SUMMARY
OF CORRECTED DATA The Summary of Measured Data presents the individual containment atmosphere drybulb temperatures, dewpoint temperatures, absolute total pressure and free air volume measured at the time and date.
1.
TEMP 1 through TEMP N are the drybulb temperatures, where N = No. of RID's.
The values in the right-hand column are temperatures (*F), cultiplied by 100, as read from the data acquisition system (DAS).
The values in the lef:-hard column are the corrected temperatures expressed in absolute units
(*K).
2.
PRES 1 through PRES N are the total pressures, absolute, were N = No.
of pressure sensors. The right-hand value, in parentheses, is a number in counts as read from the DAS. This count value is converted
(N to a value in psia by the computer via the instrument's calibration
\\_sl table, counts versus psia.
The left-hand column is the absolute total pressure, psia.
3.
VPRS 1 through VPRS N are the dewpoint temceratures (water vapor pressures), where N = No. of dewpoint sensors.
The values in the right-hand colu=n are te=peratures (*F), multi-plied by 100 as read from the DAS.
The values in the left-hand column are the water vapor pressures (psta) from the steam tables for saturated steam corresponcing to the dewpoint
( s a tu ra t io n) temperatures in the center column.
The Sum =ary of Corrected Data presents corrected temperature and pressure values and calculated air mass determined as follows:
1.
TEMPERATURE (*R) is the volume weighted average containment atmosphere drybulb temperature derived f rom TEMP 1 through TEMP N.
2.
CORRECTED PdESSURE (psia) is the partial pressure of the dry air cocconent of the containment atmosphere, absolute.
The volume weighted average containment atmosphere water vapor pressure is subtracted from the volume weighted average total pressure, yielding the partial pressure of the dry air.
O
3.
VAPOR PRESSURE (psia) is the volume weighted average contain-ment atmosphere water vapor pressure, absolute derived f rom VPRS 1 through VPRS N.
A-10
4 VOLUME (cu. ft.) is the containment free air volume.
5.
CONTAINMENT AIR MASS (lba) is the calculated mass of dry air in the containment. The mass of dry air is calculated using the containment free air volume and the above TEMPERATURE and CORRRECTED PRESSURE of the dry air.

APPENDIX H LOCAL LEAKAGE RATE TESTING EVALUATION During refueling outages, local leakage rate testing (LLRT) is commenced at the beginning of the outage and completed in approximately six to eight weeks. The ILRT, if scheduled for that outage, is conducted after the completion of the LLRT.
During the.LLRT, repairs and adjustments are made to some systems which may change that penetration's leak rate. The term "As Found" indicates the leak rate before repairs and adjustments and the term "As Left" is'the leak rate after repairs and adjustments. An evaluation of the difference between "As Found" and "As Left" can give only some indication of what the ILRT results would be if conducted prior to repairs and adjustments.
Table 1 is a comparison of the "As Found" and "As Left" data for those penetrations which had repairs and adjustments performed during'the LLRT.
Units of measured leak rate are standard cubic centimeters per minute (sces).
