information:

• What cues are provided to personnel that manual action(s) is/are required?

• What cues are provided to personnel that the proposed action(s) is/are no longer required?

• What administrative controls exist to assure that, when the action(s) is/are no longer required, the plant configuration is put in the correct configuration for the plant status? 2. Please describe any changes to operating procedures needed to support the proposed license amendment. 3. If the Emergency Operating Procedures are affected, describe any changes that were required of the Control Room task analysis that was done as part of your Detailed Control Room Design Review. If no update to the task analysis was necessary, describe how task requirements were developed. 4. Please describe any changes to controls or displays (including annunciators and alarms) needed to support the proposed license amendment. 5. Please describe any changes to training and the simulator needed to support the proposed license amendment. 6. Please describe any changes to staffing or qualification needed to support the proposed license amendment.
