leak rate calculations are presented in A ?pendix C. The measurcd ccinbined leakage during perfomance of the verification test was 0.4262 wt l/ day as ccupared to a predicted value of 0.5023 wt 1/ day.
This comparison is well within the required accuracy prescribed in 10CTR 50, Appendix J. Data and leak rate calculations for the !
supplemental verification test are included in Appendix D. l 2.2 LpeBandTypeCTestResults_
11uring Novanber 1974 and January 1975, local Icak rate tests were conductcd on selected testable penetrations, gasketed seals, doors, i
and isolation valves. Results of all tests were reported in Smi-Annual Reports No. 8 and No. 9, July 1,1974 to Decmber 31, 1974 ,
and January 1,1975 to June 30, 1975, respectively, to the USN'RC. t Ihring September, O'tober and Novmber,1975, local leak rate tests '
were conducted on all testable penetrations, gasketed seals, doors and isolation valves. Results of all tests were tabulated ir Appendix A and stmari:ed in Tabic 1.
A separate stmary report of all Type C tests which falla! to meet the leakage acceptance criteria of the Technical Specifications and a discussion of the repairs acccuplishcd is includcd in Appendix B.
All isolation valves with Icakage in excess of the individual valve ,
leakage limit were restored to acceptable leak tightness. Total leakage for double gasketed seals and total Icakage for all other penetrations and isolation valves following repairs satisfied the Technical Specification limits.
- 3. Descrigtion of Test prceedures 3.1 Type B ard Type C Test procedure All tecto vere conducted with air or nitrogen usire the precoure deeny or rotmeter methcds. The rotameter method was also used to estinate gross leakage. The voltrne between redundant isolation valves, the center of double gasketed seals, or the voltrne of an expansion bellows, electrical penetration, or hot fluid piping penetration was pressuri:ed slightly above test pressure. Conditions were allowat to stabilize and the pressure decay or rotameter indicated flow was measured. In tests ,
usir.g the pressure deeny ::ethod, the decay rate at Pt was cbtair,ed by interpolation of the test data and used in conjunction with the known test volume to calculate the leakage rate. Tmperature corrections were not made because of the difficulty of positioning a tmperature sensor in the test voltrne. In addition, it is dmonstratcd in the error analysis that these corrections are small cmpared to other uncertainties in the testing procalure. Rotameter tests were vented to the atmosphere. Temperature and :
pressure corrections were made based upon rotameter calibration.
Isolation valves were tested either singly or several in the same line were testod simultaneously depending upon the location of installcd test L r-- -

Result s fran leakage test s cornlucted using nitrogen were cor7 Wted to equivalent air leakage rates.
3.2 Type A Test Procalute 3.2.1 Type A Test instrtnentr. and rguipent The integrated contairnent leahage rate test was conducted using the reference vessel methcd specifini in ANSI " 45.4 1972. The principal measuring instrtnents consistal of a reference chamber systan, a 36 inch U tube mananeter, a 0 60 psin Wallact Tiernan gauge, 20 tanperature trans-mitters with platinum resistance tenperature sensors, and six Foxboro dewcels.
The reference ch:nber (Figure il consistal of three sections sized in pro;ortion to the containment vohene represented by each. All sections were fabricatal frm 2-inch thin wall cop?er pipe connected by 1/4 inch copper tubing. Prior to the integratal leatage test the reference syston was evacuated and filled with dry nitrogen. The reference systan and all instm-ment piping was then subjectal to a 24-hour leak test at 50 psig using the absolute method specificd in ANSI N-45.41972. The reference systan leak test was also conductcd at the conclusion of the integratal leakage rate test. In both instances, the reference system was verified to have essen-tially zero Icakage under test conditions.
The U tube mananeter (Figure 2) was usal to measure reference chxnber-containnent differential pressure. Pressure gauge PI 1 was used to insure that reference chxnber pressure vas higher than containment pressure when the mananeter was placed in service. Yalves E, F and G were opencd first to pennit a sml] anount of dry nitrogen to flow frm the reference systan into contairnent thereby equalizing pressures. This procedure prevents the introduction of moisture into the reference system.
Closing valve E then places the mananeter between reference system and containnent atmospheres. Valve E is leak tested as part of the initial 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> reference systan leakage test.
The Wallace Tiernan Model 1500 pressure gaum, PI-2, was usal to indicate contairnent pressure. This gauge was certified by the manuf acturer's cmparison with a calibrating startlard traceable to Natural P.ureau of Standards.
Rosanaant Mcdel 442A ALPittLINE Tanperature Transmitt ers were plaeal through-out the contairnent to monitor tmperature. The tunperature sensing systun consistal of twenty individaal 2- wire temperature transmitters each cannectal to a platinton resistance tunperature sensor and a regulated IC power supply. Each resistance tanperature detector was assigncu a weight-ing f actor proportional to the voltrne monitored for use in calculat ing the average contairnent temperature. Tables 2 and 3 list the resistance tanperature detector Itcations and assigned weighting factors. The RID signals were transmittal to the plant process conjuter where a ten minute average of the tunperature at eacn ic.c9 was printed by the couputer typer in degrees F.

.S.
- Foxboro Fbdel 2701 RPG deweels were used to monitor containment vapor pressure. Each dewcel was assigncd a weighting factor proportimal to the containnent volme monitored for calculation of average vapor 3ressure. Tables 2 and 3 list the deweel locations and assigned weigiting factors. The deweel signals were transmittcd to the plant process canputer via resistance to current converters arxi a ten minute average of the vapor pressure at each locale was printed in inches of water by the cmpster typer. Readin a the dewcel resistance and conversion to vapor pressure was accceplismi by entering the requircd calibration curves into the cunputer mencry.
Calibr:..' ion was checked using a certified resistance decade lox to simulate each deweel RTD.
Addi'.lonal data on the integrated leakage rate test inst rtunent s are sternarind in Table 4 The containment was pressurized using 3 750 cfm portable diesel air compressors (Figure 3). The air was cooled using an air treat-ment pressurizing skid. The air was supplicd and meter (d to the drywell through a flange connection on the nitrogen purge system.
Contalment ventilation was providcd by a two spe(d drywell ventilation fan operating at low speed arxi six portable 10,000 cfm electric fans equippcd with oversi:cd motors to prcnote mixing of the air.
3.2.2 Type A Test Stemary of Events The pre test containment inspection was canpletod on Novanber 1Cth with r.a visible structural deterioration found. !bjor preliminary steps were cunplet(d and incitdcd:

Derivation of the leakage rate equation may be found in ANSI N 45.4-1972 Appendix B.
The purpose of the hourly calculations was to construct a plot of point to-point Icatage rate (Figure C-1). This plot was useful in detecting trends or possible anmalies. The actual containment Icabge rate however, was taken as the average of data comparisons from five 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> intervals. The first five hours of data following stabili:ation of the contalment atmosphere and the last five hours of data were used for this pirpose. All data arwl calculations for the integrated containment leak rate test are tabulated in Appendix C.

- 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 voltne of the test rig was used as the test volume. For the drys: ell head, twice the voltne of the test rig was used as the test volume.
The expansion bellows penetration similarly have a small voltne and the voltne of the test rig was used as the test volume.
- 3. The Technical Specification for doubic-gasketed seals is that the total leakage not exceed 34.4 scfh/hr 9 41 psig. -
No specification is given for an individual double-gasketed seal.
- 4. The "as left" Icak rate for these penetrations was the leak rate measured i.nediately prior to the integrated leakage rate test. All Type B penetrations opened for the outage were retested when closed.
- 5. Drywell head "as found"is"as left"Icakage from previous outage. Could not test due to bad test connection.
After maintenance, seals were tested after re-installation. l 1

APPINDIX B SU5tARY REPORT OF ALL TYPE C TESTS FALLING TO MiET~ TIE LEAkTLETCCIWARCE CRITERIA Fall 1975 Local leakage tests were conducted on all testable isolation valves during the Fall 1975 hbnticello refueling outage. Of the 76 valves tested,12 failed to meet applicable individual Icakage limits. The following is a sunnary of the causes of leakage and corrective actions taken for these valves: a) bhin Steam Isolation YaIves Three MSIV's were found to exceed the Technten1 Cpecification leakace 'mit and the initial tert result o for or.e addit ior.nl PCIV were quert ionnble. All were dirassembled. L defeetr> rarh as cracks, chips, or ceratchec could be observcd. The pilot valve and main poppet seats were lappcd on all four valves and they were renscembled. All valves exhibited zero leakare fol10wir1c :epnier, b) Core Spray Isolation Check Valves Both core check valves, A014-13A and A014-13B, were disassenbled and the valve internals examined. The cause of Icakage was detennined to be an accunulation of scale on valve seating surfaces of both valves. The valve seats were cleaned and valves reassembled, with satisfactory leak testing following reassanbly. c) Drywell Equipnent Drain Stop Isolation Valves Both drywell equipnent drain strnp isolation valves, A0 2561A and A0 2561B, were separately disassanbled and examined. A piece of flexitallic gasket from maintenance work on an upstream valve was found lodged in the seat of A0 2561A. Valve seats in both valves were c1 caned and the valves were reassenbled. The valves were subsequently satisfactorily tested, d) Standby Liquid Control Isolat ion Check Valve The SBLC Isolation Check Valve, XP-6, was disassembled and examined, reveal-ing scale acctraulation on the valve seating surface. The valve seat was cleaned and lapped anl the valve reassembled and satisfactorily tested. e) Control Rod Drive Isolation Check Valve CRD-31 was disassenbled and found to have scale accunulations on the valve seat ing surface. The valve seat was cleaned and lapped, valve reassunbled and satisfactorily tested, f) Shin Steam Inboard Drain Isolat ion Valve Leak testing between the nain steam line drain isolation valves, SD 2373 and 2374, showed that the inboard valve, N 2373, was leaking excessively.
25 - APPINDIX B (contd) Due to high contact exposure rate, the valve seating surface and valve intemals were not inspected. The valve was replaced with a similar valve and both isolation valves were then satisfactorily leak testod. g) HPCI 'Ibrbine Exhaust Check Valve The llPCI Turbine Exhaust Check Valve, HPCI-9, was disassembled and examined. Scratches were found on the valve seating surface. The valve seat was cleaned and lapped and the valve was reassanblal. A satisfactory leak test followed maintenance on the valve. i \ l i l l l l
