CONTAINAENT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

4. Verifying that the torque required to keep each door from closing R135[ ;

is greater than 78 inch pounds when the door is 40 degrees open. 1 This torque is defined as the " door closing torque" and is equal i to the nominal door torque minus a frictional torque component. R135 l

5. Calculation of the frictional torque of each' door tested in accordance with 3 and 4, above. The calculated frictional )

torque shall be less than or equal to 40 inch pounds.

4.6.5.3.2 Intermediate Deck Doors - Each ice condenser intermediate deck door shall be: j

a. Verified closed and free of frost accumulation by a visual )ction at least once per 7 days, and

b. Demonstrated OPERABLE at least once per 18 months by visually verifying R135 no structural deterioration, by verifying frce movement.of the vent I i assemblies, and by ascertaining free movement when lifted with the I applicable force shown below:
