. demonstrate the operability of valves VQ2A, VQ3B, VQ15B and VQ16A. The following information.is provided to supplement the previous submittal.

As noted;in'.the September 5,1984 submittal, all four valves were supplied with'Rotork; electric. motor. operators set at 45 ft-lbs of' output torque.

This -torque is.'more than adequate' to assure valve closure against accident.
