ATTACHMENT 3-7B MANUAL ACTIONS REQUIRED FOR HOT SHUTDOWN IN APPENDIX R III.G.3 FIRE AREAS/ZONES (NOTE 1)
SHEET 7 Rev. 27 Column Heading Notes:
(1) Condition which requires action (Equipment Failure):
This is the condition that requires compensatory action to achieve safe shutdown. Some actions are performed based on an observed equipment failure but some are proactive.
Proactive actions are performed based on the condition described. The reason for the action (potential equipment failure) may be identified in parentheses.
(2) Applicable Fire Areas / Zones:
List all of the fire zones where this manual action (item 3) is required for a successful safe shutdown strategy.
(3) Action Required:
This is a single action or group of actions, which are performed together if the condition exists. For example, cross tie DC buses is a single line item because these steps would be done together for a single common purpose.
(4) Fire Area/Zone of Action Location (Description):
List the Fire Areas (or Zones) where the actions are performed. A more detailed description may be identified in parentheses.
(5) Time Requirement:
Describes the maximum acceptable time for completion of the action. The starting time is the condition in column (1) unless otherwise noted.
(6) Time Requirement Basis:
References the technical basis or document for the time requirement.
(7) Emergency Light(s):
The lights required at the location where the action is required are identified. Pathway lighting to a component is not included.
NOTES:
(1) The table includes action taken inside and outside of the control room. No exemptions are required for these actions.
(2) For all MOVs, it is assumed that the breaker for the locally operated valve will be opened prior to valve operation. This is part of the required manual action.
(3) Control Room Evacuation Analysis 86-9101191-001 provides the basis for the action time. This time has additional conservatism because the analysis is based on RCS inventory loss rate with Westinghouse RCP seals.
(4) Technical Evaluation 352410-33 provides the basis for the action time. This time has additional conservatism because the analysis is based on RCS inventory loss rate with Westinghouse RCP Seals.
(5) ECR 07-00702 provides the basis for the action time. This time has significant conservatism because CO-V-111A is now normally closed.
