IR 96-006, NRC Inspection Report; NRC Commitment for Operations procedures PMT/QC reviews.

3.0 PRECAUTIONS AND LIMITATIONS 3.1 Previous tests have shown that dust accumulation in the spray header when air is cut in is minimal. SA supply should be throttled to the minimum required to cause streamer response.

3.2 Ensure adequate fall protection is used when performing nozzle air flow checks from polar crane.

I 4.0 INITIAL CONDITIONS s

4.1 Plant in refueling or cold shutdown.

4.2 The reactor vesselis not open to containment atmosphere, or a debris screen is installed.

4.3 Service air available for test connections in containment.

4.4 Polar crane available for access to spray nozzles.

4.5 20' reach pole with streamers available Ql

4.6 Open end wrenches and sockets sizes 1-1/16" and 1-1/4" are available.

l' 4.7 Torque wrench (es) available for torqueing bolts to 60 Mbs and 165 Mbs.
