Note 5.0 Test Equipment 5.1 Flashlight 5.2 Hot-wire anemometer 5.3 Ladder 5.4 Tape Measure 6.0 Limits and Precautions 6.1 Follow HP guidelines for entry into operating filter package.

6.2 Use caution during testing to avoid placement of ladders, personnel, etc. such that velocity readings would be affected.

7.0 Required Unit Status None d

8.0 Prerequisite System Conditions Initial /Date

/ 8.1 The Unit 1 VA F' tered Exhaust Package is running in filter mode (keyswitch tui . .i TEST) with both Unit 1 VA supply fans on.

9.0 Tept Method A traverse of the vertical entry and exit slots for the VA carbon adsorber bed will be performed with an anemometer. Ten data points will be recorded for each of the upstream and downstream flow paths in order to analyze flow distribution.

! Initial /Date NOTE: IV means independent verification is required.

/ 12.1 Prerequisites are met and Limits and Precautions have been reviewed.

/ 12.2 Record VA filtered exhaust flow rate as read by i IMVAPG9370: cfm.

/ 12.3 Enter VA filtered exhaust package between the downstream KEPA face and carbon adsorber bed, and ensure door is closed.

]

/ 12.4 Complete all data blanks as required by Enclosure 13.1.

/ 12.5 Exit filter housing, beir.g sure to remove all test equipment.

/ 12.6 Enter filter housing between the carbon adsorber bed and the j downstream isolation damper.

CAUTION: At this point in the filter housing, the only components between personnel and the exhaust fans are the l downstream isola *. ion dampers. Use care such that personal protective equipment and test equipment is not drawn into fans.

/ 12.7 Ensure access portal is closed.

/ 12.8 Complete all data blanks as required by Enclosure 13.2.

/ 12.9 Exit filter housing, being sure to remove all test equipment.

l / 12.10 Ensure all VA filter package doors, entry ports and sample l / IV ports are properly sealed.

/ 12.11 Perform calculations as required by Enclosure 13.3.

Last Calibration Calibration Due

2. Divide each of the 20 vertical inlet slots into 10 equal sections, using the tape measure. Perform velocity measurements with the anemometer at the center of each

of these 10 sections for each of the vertical slots. Record readings in the

, corresponding blanks below.

i NOTE: Vertical inlet slots are numbered from left to right, as viewed facing downstream. Data is recorded from the 10 equal sections from top to bottom.
