3.5*

Per Technical Specification 15.3.8.7, the containment purge supply and exhaust system shall be demonstrated operable by verifying isolation occurs on both high radiation trips and manual initiation within four days prior to and at least once per seven days during refueling operations.

3.6*

The containment parsonnel hatch doors shall be capable of being closed which means that other than the hatch door 0-ring protectors, no other equipment can be placed in or run

Certain steps of thisprocedure may be commenced at any time as i

long as they do not adversely affect the overallsequence NOTE:

Certain steps ofRP-1B request level changes be made to the refueling cavity and reactor vessel These level changes shall be made byperforming the appropriate steps of OP-4D.

51 Verify the fuel transfer system gate valve is shut and CL-lE updated.

5.2 Position the fuel transfer cart per 01-53.

5.3 Lower refueling cavity water level per OP-4D, Pan 3 or 4 to that desired for upper internals installation, ~60.5 A. cavity level.
