/

1.0 Purpose To determine air flow velocity profile for prefilter entry and HEPA exit in the VA filtered exhaust package.

2.0 References 2.1 ANSI N-510, Rev. 1980 2.2 ANSI N-510, Rev. 1975 2.3 TP/0/A/1450/02 3.0 Time Required One test coordinator and technician for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

4.0 Prerequisite Tests None 5.0 Test Equipment 5.1 Flashlight 5.2 Hot-wire anemometer 5.3 Ladder 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 8.0 Prerequisite System Conditions Initial /Date

/ 8.1 The Unit 1 VA Filtered Exhaust Package is running in filter mode (keyswitch turned to TEST) with both Unit 1 VA supply fans on.

9.0 Test Method A traverse of the upstream face of the VA filter package prefilters and the downstream face of the KEPA filters will be performed with an anemometer. Thirty-five data points will be recorded for each plane in l

I order to analyze flow distribution.

TT/1/A/9100/101A Page 2 of 3 10.0 Data Required 10.1 VA filtered exhaust system flow rate (as read by in place instrumentation).

10.2 Air flow velocity readings as specified by enclosures (as read by anemometer).

10.3 Average velocities and worst case high and low percent deviations as calculated on Enclosure 13.3.

11.0 Acceptance Criteria 11.1 Results of velocity distribution data will be evaluated by Design Engineering to determine effects on residence time and representative carbon sampling per MCC-1211.00-00-0096, Acceptance Criteria for Supplemental Filte Testing.

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

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

/ 12.6 Enter VA filtered exhaust package between the downstream HEPA l

face and carbon adsorber bed, and ensure door is closed.

/ 12.7 Complete all data blanks as required by Enclosure 13.2.

/ 12.8 Exit filter housing, being sure to remove all test equipment.

/ 12.9 Ensure all VA filter package doors, entry ports and sample

/ IV ports are properly sealed.

/ 12.10 Perform calculations as required by Enclosure 13.3.
