RAI-]
With the removal of option 'b' from TS surveillance requirement 3.5.2.1, what changes will be made to Emergency Operating Procedure 5.8.14, 'Suppression Pool Make Up Systems,' or other procedures?
NPPD Response Procedure 5.8.14 provides makeup to the suppression pool from the CST and other sources.
Removal of option b from Technical Specifications does not affect providing makeup to the suppression pool using Procedure 5.8.14; therefore Procedure 5.8.14 does not require any changes.
Removal of option b from Technical Specifications will affect two other procedures. Procedure 2.2.9, Core Spray (CS) System, Revision 75, and 2.2.69.1, Residual Heat Removal (RHR) Low Pressure Coolant Injection (LPCI) Mode, Revision 26, were revised to specify that RHR and CS are inoperable when the pump's suction is aligned to CST A.
RAI-2. 1 Ident~ify any operator actions that will be changed, deleted, or added in support of this LAR? If actions will be changed or added, will any of these actions be time critical? If yes, discuss.
NPPD Response This LAR removes an option to align RHR and CS suctions to CST A and remain OPERABLE.
This option was used infrequently and only while the plant was shutdown. The procedures that contain this guidance are still in place but have been revised to specify that RHR and CS are inoperable when their suctions are aligned to the CST. No time critical operator actions are involved.
NLS20 15086 Attachment Page 2 of 2 RAI-2.2 Identify any affected procedures by number, title, revision, and a brief summary of the change(s) necessary to support this LAR.
NPPD Response Procedure 2.2.9, CS System, Revision 75, and 2.2.69.1, RUR LPCI MODE, Revision 26, were revised to specify that RHR and CS are inoperable when their suctions are aligned to the CST.
RAI-2. 3 Identfify any changes to training that are required to support this LAR.
NPPD Response As part of the license amendment implementation, the training lesson plans for CS and RHR systems will be revised to remove reference to operability when the system is aligned to take suction from the CST. Also, the lesson plan for Technical Specifications Section 3.5 will be revised to remove the reference to CST water level >14 feet, taking credit for CST suction during Operations with the Potential to Drain the Reactor Vessel, and reference to the CST as a suction path for operability.
RAJ-2. 4 Will any changes to the control room displays, controls, alarms, or annunciators, or the Safety Parameter Display System be required to support this LAR?
NPPD Response None required. This alignment is not mimicked on any Control Room display, has no controls in the Control Room, is not alarmed in the Control Room, and is not in the Safety Parameter Display System.
RAI-2. 5 Will validation of the feasibility and reliability of new or changed operator actions be performed? If not, why not?
NPPD Response No, no operator actions were changed.
