I. INTRODUCTION This report presents data, analysis, and conclusions pertaining to the Calvert Clif fs Nuclear Power Plant Unit 1 Integrated Leakage Rate Test (ILRT) performed in May 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 Cliffs Nuclear Power Plant, Unit 1, Technical Specifications and 10CFR50, Appendix J. The Calvert Cliffs 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 from 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 BN-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 i
calculated leakage rate value is within the acceptance limits. All calculations were done with Bechtel's ILRT computer program described in Appendix A.
The temperature and pressure history and the containment air mass f variations were plotted by the computer program and are contained in Appendix E.
1 II. TEST SYNOPSIS Valve line-ups were conducted on all systems to e tablish post-accident conditions except for shutdown cooling, steam generator aanways and manholes and three penetrations necessary to conduct the ILRT. The inspection of the containment's accessible interior and exterior surfaces was conducted prior to pressurization. No evidence of structural deterioration was noted which would have affected containment integrity or leak tightness.
Containment pressurization commenced at 1:00 pm, May 18,1985. At 3:30 pm, pressurization was stopped to investigate an observed 100 inch water level decrease (approximately 3000 gal.) in the pressurizer. At 5:25 pm the pressurizer was refilled and pressurization restarted. At 7:45 pm the sumps were drained due to a high sump water level reading.
O-SU-084 1
Test pressure of 50.5 psig was reached at 2:44 am, May 19,1985. The O) i s
pressurization line was vented and the containment coolers and fans were stopped in stages between 3:00 am and 6:40 am. Containment pressure continued to increase due to increasing containment temperature. In order to satisfy procedural requirements on the test pressure, the upper limit on the test pressure was raised from 50.5 psig to 52.0 psig. The temperature stabilization criteria were satisfied during the four hours f rom 9:30 am to 1:30 pm.
Collection of data to determine the integrated leakage rate commenced at 1:30 pm, May 19,1985 and was completed at 11:30 pm. The verifica-tion flow test was initiated at 0:30 am, May 20, 1985. The verifica-tion flow test was completed satisf actorily and depressurization of the containment commenced at 7:40 am, May 20, 1985. After the containment was completely depressurized at 10:30 pm, May 20,1985, a containment entry was made. Determination was made that no measurable water level changes requiring corrections to the measured leakage rate had occurred during the test. Summary of test phases were as follow:
Time Duration hr. Date Test Phase 1300 - 0244 14.73 May 18-19 Pressurization 0245 - 1315 10.5 May 19 Stabilization 1330 - 2330 10.0 May 19 ILRT

Temperature sensor 13, located in ill steam generator cavity indicated a decreasing temperature starting at 9:30 am on May 19. Since all other temperature sensors indicated an increase in temperature, sensor 13 was judged to be malfunctioning and its volume fraction assigned to temperature sensor 6, located in #12 steam generator cavity. Tempera-ture sensor 14 consistently indicated temperatures approximately 6 to 7'F lower than adjacent sensors which was inconsistent with the tem-perature survey. Sensor 14 was judged to be malfunctioning and its volume fraction assigned to temperature sensor 12, located at the same elevation. The reassigned volume fractions were used to calculate the containnent dry air mass during the entire test. Plots of temperature sensors 13 and 14 are in Appendix I.

-- APPENDIX A DESCRIPTION OF BECHTEL ILRT COMPUTER PROGRAM A. Program and Report Description
- 1. The Bechtel ILRT computer program is used to determine 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 Rate Testing of Primary Containment Structures for Nuclear Power Plants".
The program is designed to allow the user to evaluate containment leakage rate 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, yielding three different report printouts.
- 2. In the first printout, the Total Time Report, leakage rate is com-puted from initial values of free air volume, containment atmosphere
~
drybulb te'mperature and partial pressure of dry air, the latest
('
( values of the same parameters, and elapsed time. These individually computed leakage rates 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 56.8-1981,
" Containment System Leakage Testing Requirements." The mass of dry air in the containment is computed at each data point (time) using the Equation of State, from current values of containment atmos phe re 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 as a function of number of data points and elapsed time (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.

E. COMPUTER REPORT AND DATA PRINTOUT MASS POINT REPORT The Mass Point Report presents leakage rate data (wt%/ day) as deter-mined by the Mass Point Method. The " Calculated Leakage Rate" is the valce determined from the regression analysis. The " Containment Air Mass" values are the masses of dry air in the containment (Ibm).
These air masses, determined from the Equation of State, are used in the regression analysis.
TOIAL TIME REPORT The Total Time Report presents data leakage rate (we%/ day) as deter-mined by the Total Time Method. The " Calculated Leakage Race" is the
[
N~s -
value determined from the regression analysis. The " Measured Leakage Rates" are the leakage rate values determined using Total Time calcu-lat io ns . These values of leakage rate are used in the regression analysis.
TREND REPORT 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 l
of data points.

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 f ree air volume measured at the time and date.
- 1. TEMP 1 through TEMP N are the drybulb temperatures, where N = No . o f RTD' s . The values in the right-hand column are temperatures (*F), multiplied by 100, as read from the data acquisition system (DAS). The values in the left-hand column are the corrected temperatures expressed in absolute units
(*R).
- 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
(,g) table, counts versus psia. The left-hand column is the absolute total pressure, psia.
- 3. VPRS 1 through VPRS N are the dewpoint temperatures (water vapor pressures), where N = No. of dewpoint sensors. The values in the right-hand column are temperatures (*F), multi-plied by 100 as read from the DAS. The values in the left-hand column are the water vapor pressures (psia) from the steam tables for saturated steam corresponding to the dewpoint (saturation) temperatures in the center colu=n.
The Summary 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 from TEMP 1 through TEMP N.
- 2. CORRECTED PRESSURE f psia) is the partial pressure of the dry air component of the containment atmosphere, absolute. The solume weighted average containment atmosphere water vcpor pressure is subtracted from the volume weighted average total pressure, yielding the partial pressure of the dry air.
- 3. VAPOR PRESSURE (psia) is the volume weighted average contain-fN atmosphere vater vapor pressure, absolute derived from ment
() 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 l
the containment free air volume and the above TEMPERATURE and '
CORRRECTED PRESSURE of the dry air.

G 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 af ter 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 Lef t" is the leak rate after repairs and adjustments. An evaluation of the difference between "As Found" and "As Lef t" 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 Lef t" data for those penetrations which had repairs and adjustments performed during the LLRT.
Units of measured leak rate are standard cubic centimeters per minute (secm).
