1. Introduction  ;

i 1.1 Pumose of Containment Leakage Test y , As stated in 10 CFR 50, Appendix J, primary containment leakage tests j are conducted to assure that. , i i a) leakage through tb primary reactor containment and systems and  ! components penetrating primary containment shall not exceed i allowable leakage rate values as specified in the Technical 4 Specifications or associated Bases. (, j b) Periodic surveillance of reactor containment penetrations and i isolation valves is performed so that proper maintenance and

repairs are made during the service life of the containment, and ,

j systems and components penetrating primary containment. l ! Results of containment leakage tests are' reported to the Directorate

of Licensing, USAEC, following each periodic containment integrated i

{ 1eakage test (Type A test). This report must include. l - I 3 a) Analysis and interpretation of the Type A test results. l b) Results and analysis of the supplemental verification test employed l to demonstrate the validity of the leakage rate test measurements. l i i 1.2 Testing Requirements i i

1.2.1 Frequency of Testing I Type / tests are scheduled in accordance with Paragraph 4.7.A.2 (d) l
of the hbnticello Technical Specifications. Testing is required at 1 the following intervals

i

a) During the first refueling outage.

) b) Within 24 months of the test in (1) above. \ l c) Within 48 months of the test in (2) above and every 48 months l thereafter. In the event that any testing (local or integrated) yields a leak rate l ~ in excess of Lt =-1.2 weight percent of the contained air per 24 hours , at the test pressure P t" 41 Psig, the condition must be corrected and j the testing schedule reverts to. i l a) At the first refueling outage following the retest made (local or l ! integrated) to correct the excess leakage.  ! 2 j l 3 b) Within 24 months of the test in (1) above. l c) Within 48 months of the test in (2) above and every 48 months thereafter. 1 1

A block valve was provided in the solenoid valve exhaust port and the containment was re-pressurized to 42 usig. Conditions were determined to be sufficiently stable for meaningful and consistent data by 1520. Data was logged hourly and a point-to-point calculation of leakage rate was plotted to detect possible spurious readings. At 2120 on May 14, 30 hours of usable data had been collected and the integrated containment leakage rate test was considered complete. ' The controlled bleed verification of the test accuracy was begun at 2125. At 0425 on May 15, sufficient data had been collected to verify the accuracy of the integrated leakage rate test within the allowable accuracy of 10 CFR 50, Appendix J. The containment was depressurized through the dr well 'and torus 2-inch vent lines to the Standby Gas Treat aent System. At 1715 on May 15, depressurization was compleved and the , containment was inspected. No damage was discovered.

4. Summarv of Test Calculations, 4.1 Containment Volume Calculations The containment volume calculation was based on detemination of pressure rise resulting from introduction of a measured quantity of air into the containment during pressurization to 42 psig. The calculation utilized the perfect gaslaw as corrected for the water vapor present.

1 l . The purpose of the hourly calculations was to construct a plot of point-to-point leakage rate (Figure A-1). This plot was , useful in detecting trends or possible anomalies. The actual  ! containment leakage rate, however, was taken as the average of data comparisons from six 24-hour intervals. The first six hours of data following stabilization of the containment atmosphere and the last six hours of data were used for this purpose. All data and calculations for the integrated containment leak rate test are tabulated in Appendix A. 4.3 Calculations for Verification of Type A Test Accuracy seven hrs of useful data were taken with a controlled leakage rate established in addition to the nomal containment leakage rate. The integrated leakage rate test validity was established by comparing Ly' and L y, where: L'=L y c ~l o Ly= bbasured integrated leakage rate (wt %/ day) Lc= Leakage measured during controlled bleed (wt%/ day) Lg= Controlled bleed rate (wt%/ day) As described in 10 CFR 50, Appendix J, results from the controlled leak testLare acceptable provided y L ' allowl

2. The volumes of the toroidal spaces in the double-gasketed seals are uncertain due to' the presence of flexible rubber, and in any case are quite small. For all seals except the drywell head, the volume of the test rig was used as the test volume. For the drywell head,

, twice the volume of the test rig was used as the test volume. The expansion bellows penetration similarly have a small volume and the volume of the test rig was used as the test volume.

3. The Technical Specification for double-gasketed seals is that the total leakage not exceed 34.4 scfh/hr 0 41 psig. No specification is given for an individual double-gasketed seal.
4. The "as left" leak rate for these penetrations was the leak rate measured imediately prior to the integrated leakage rate test. All Type B penetrations opened for the outage were retested when closed.
  • Refueling outage valve leakage problems and corrective measures are summarized in Mr. L.O. Mayer's letter to Mr. J.F.0' Leary dated May 20,1974.
