UNIT 2 INITIALS 4.3 Staging and pretest of Volumetrics test rig.

4.3.1 Station the Volumetrics test rig in an area not subject to draft or cold weather.

4.3.2 Route P-tubing from the test rig to the 2RM-211/212 cubicle at valve 2RM-3200Y but do not connect to 2RM-3200Y.

4.3.3 Install a Swageloc cap at the extreme end of the tubing.

4.3.4 Adjust the pressure regulator of the test rig for a supply pressure of 15 psig and pressurize the test rig and P-tubing.

4.3.5 When a stable test system leak rate is achieved: l

a. Correct any substantial leak paths in the test system. The l leakage at the end fitting of the P-tubing should be zero.

l

b. Record the as-left baseline test system leak rate on the test '

data sheet for the 15 psig test.

4.3.6 Adjust Volumetrics test pressure for 4.0j psig in preparation for the low pressure test.

4.4 Permission to Perform Test The conditions required by this test are consistent with required plant conditions including equipment operability. Permission is granted to perform this test. ,

DSS Time Date I 5.0 PROCEDURE 5.1 Place the control switch for 2P-707B, containment forced air blower, to

" PULLOUT."

NOTE: Ifunit is atpower, LCO entrypoint.

4 5.2 Secure 2P-707A sample pump.

5.3 Position the " MODE SELECTOR" on 2C-20 for the containment air sampling system to the " CONTAINMENT" position.

{

5.4 Align the system per Attachment A.

5.5 Connect the Volumetrics test rig to 2RM-3200Y, septum SA purge test connection.

,

  • CAUTION
  • THE TEST PRESSURE OF 65 PSIG PER OI-58 DOE'S NOT APPLY TO THIS TEST. DO NOT EXCEED 5 PSIG l TEST PRESSURE, THE DESIGN PRESSURE OF THE i, MYLAR WINDOW OF 2RE-211&212.
5.6 Open 2RM-3200Y and raise the system pressure to 4.0 psig per 01-58.

5.7 When a stable pressure and leak rate condition is achieved, record data on the test data sheet.

i 5.8 When the 4 psig test is complete, position the " MODE SELECTOR" on '

2C-20 to the " SEPTUM" position.

, 5.9 Shut the following valves:

1 2RM-1,2P-707A bypass regulator inlet isolation

. 2RM-3200K,2RE-211&212 inlet manual isolation 4

i 5.10 Slowly unscrew the glass bowl of the 2RE-211/212 bypass line filter to i vent 2RE-211/212 to atmosphere. When 2RE-211/212 is depressurized,

then remove the bowl to protect 2RE-211/212 from an overpressure condition in the subsequent test.

( INITIALS 5.11 Using the Volumetrics test rig, raise system pressure to 15 j psig per OI-58. l 5.12 When a stable pressure and leak rate condition is achieved:

i i 5.12.1 Check with Snoop and correct any leakage to atmosphere at mechanicaljoints, fittings, valve bonnet and packing gland, etc.

within the test volume.

5.12.2 Record data on the test data sheet.

5.13 If the corrected leak rate, as determined by subtracting the baseline l leakage of Step 4.3.5.b, is >10 scem, then locate the source of the leakage

by systematically isolating portions of the system using l valves 2RM-3200W,3200Z,3200J,3200L,3200JJ and 3200LL. Record

6.0 ACCEPTANCE CRITERION The leakage criteria of the Leakage Reduction and Preventive Maintenance Program are used to evaluate the leakage from the post-accident atmospheric sampling system. The check against Criterion 1 or Criterion 2 does not apply for this system as it is not located in the auxiliary building. The total post-accident system leakage from all areas of the plant is limited by Criterion 3. Thus, the acceptance of these test results require their evaluation together with the results of the other post-accident system leakage tests.
