SUMMARY

i 1.1 ' INTRODUCTION r .i o Consumers-Power Company's_ Big Rock Point Nuclear Plant completed .its' eleventh (in a series from 1962) reduced pressure Containment LIntegrated' Leak' Rate Test (Type A). A summary of all Type A tests is given in Table A.. The results of all Local Leak Rate i Tests (Types B and C), conducted since the previous Type A test -(October'1985) are liste'd in Table B. The containment enclosure has a net free volume of 912,891 cu ft designed for 27 psig with a calculated accident peak pressure of, ~ 23 psig. The' vessel-is made-of carbon steel plate ranging from 4 1/2" to 3/4" thick with 3/8" of mastic exterior coating; an additional'1-1/2" of polyurethane insulation.is on the top half of ? containment. The containment structure is susceptible to changes in atmospheric conditions. The weather conditions during the hold ' test were hazy, hot and humid on July-26, 1989, cloudy with rain .the_ morning of July 27, 1989, and clearing skies on the aftsrhoon of July 27, 1989. Clear: skies prevailed during thenverificatior period with cooler temperatures than the' previous two days. Outside temperatures ranged from 61'F to 85'F during the entire -- ( test. i 1.2-RESULTS = In order to fulfill the requirements of Reference 4.2, a Type A test began with pressurization on July 25, 1989 and concluded with depressurization on-July 28, 1989. The pressure at the end of the 28-hour hold test was 13.61 psig. The containment integrated leak rate at the upper 95% confidence limit was 0.00137 wt %/ day. The total as-found containment leak rate was.01768 %/ day, following additive corrections for repairs 'MI1189-0566A-BT01 4 ,-e.

A controlled leak ,;, ), (L,) of 0.355 wt %/ day was~1mposed on L,. Reference 4.4 states-g the'. measured composite leak rate (L ) shall be bound by L,+ L, ^ c g I 0.25 Lg.:1e.0.257-5 L 5 0.434 (wt %/ day), where L is,the maximum c g allowable leak 1 rate.at test pressure. The measured-composite leak rate over the verification test period was 0.273 we %/ day which met the requirements of Reference 4.3 and Reference 4.2, Section l .III.A.3.b.'and thus confirmed the Type A test measured leak rate. l. 'For a reduced test pressure of 13.65 psig, the maximum acceptable 1 leak rate for a Type A test is 0.2669 we %/ day (0.75 L ) per t Reference 4.2, Section III.A.S.b.1, including additions made fron u valve repairs prior to the Type A test, non-vented systems and water level / pressurized container corrections. Having met this acceptance: criterion, the Big Rock Point Plant-wes able to resume power = operation without further= repairing any containment penetrations and-re-performing the Type A test. l !- l-Only one plant modification affecting containment integrity ~ was completed since the 1995 Type A test. Penetration H-77 was p t dedicated for.ILRT blowdown. The applicable Type C test procedure m is TR-390. Preceding the Type A test, no post shutdown repairs or changes l' l were made to any of the containment's Type B penetrations, permitting all Type B penetrations to be tested in their true "as-found" condition.

Rock Point Type A test'have verified ' the integrity of the containment ' building and confirmed the effectiveness o'f the' Type B/C testing program. Therefore, the e ,next Type A test has been-tentatively-scheduled for the 1992 ?g refueling outage. e t$ A; compilation of all Type A test measured data and' calculations of . required Type C corrections have been filed with the working. copy of the CII.RT procedure (Reference 4.4). 1 2.0 DISCUSSION' ~ 2.1' 'ANALISIS TECHNIQUES The weighting factors used to calculate the average containment dry bulb temperatures and humidity have been calculated based on the number. of sensors within a sub-volume. The containment vapor i pressure is computed by converting.the relative humidity readings to vapor pressure and applying the appropriate weighting factors. The containment; vapor pressure is subtracted from the absolute pressure to give the containment dry air _ partial pressure.. The partial pressure of dry-air and the weighted average containment-temperature are then used to calculate the-leak rate in wt %/ day. I i L The absolute method'of-determining the leak rate.was used for this-g test and measurements were recorded every 15 minutes. The leak 7 . rate was computed using the mass point method of analysis which is l endorsed by Reference 4.1. i 'In the mass point method of analysis, data from an absolute system is. reduced to a contained mass of dry air by application of the ideal gas law. The test data consists of a time series of independent values of contained air mass. If the assumption is .MI1189-0566A-BT01 f g

w jy ( * ; ;g; i.< ,llO, (.' t e Ng1 ~ 3 E 3 i i made that the leak rate is! constant with time, the data lends "O 'itself to analysis by the method of linear least squares._ The 4 slope of.this line. represents the rate of change of air mass with l respect to time, which is the leak rate. Because of its p' independent nature, a measurement error will result in only one bad; data _ point and not materially affect the test results'. Although no data was rejected in this test, the data' rejection criteria found in Appendix D of Reference 4.1 was used by the computer program t'o' check for anomalous data. 2.2l DATA ACQUISITION-JThe. test procedure employed was the' absolute method as endorsed by Reference 4.1, Section 5. ' The instrumentation system consisted of ? _ twenty' (20), Resistance Temperature Detectors (RTDs), ten (10). . humidity (sensors land two (2) pressure sensors. The weighting- -factors used to calculate the average containment air temperature q. L vere determined on the basis of the number of' sensors within a sub-volume. 'An in-situ calibration check of all sensors was performed; n.- The sensitivities =of the RTDs,' humidity sensors and pressure- ' gauges are within the requirements established by Reference 4.1, -Section 4.2.1. The calculated Instrument Selection Guide (ISG) for the~ instrumentation system-is.019% per day which meets the requirements of Reference 4.1, Section 4.1.2. Adjustments to this calculation were not required as no sensors were lost during the test. '5 Q Sensor data was collected by a data logger (Acurex Autodata Model H. 10/10), scanned (Acurex Netpack), and transferred to a Commodore PC-compatible computer.

SUMMARY

OF TEST EVENTS 3 I The' average containment' temperature fulfilled the stabilization requir'ements of Reference 4.1, Section 5.3.1.3 and Reference 4.4,

  • Section 5.3.1, approximately six hours after pressurization was complet ed..The stabilization period was extended an additional nineteen hours in order to begin' the hold test at a specified time

.of day conducive to the BN-TOP-1 test. The hold test portion of i a the leak rate test was sta'rted at 16:00 on July 26, 1989. Approxi- } mately 8 hours into the test, ILRT personnel felt a successful short duration test was unlikely and the hold test defaulted to a minimum 24-hour duration. ' Containment parameters have been plotted to illustrate the average conditions throughout the 28-hour hold test as shown in Figures 1 through 4. The sine wave shape of the temperature, humidity pressure and containment mass profiles is exemplary of the diurnal MI1189-0566A-BT01 ..... ~
