LCSR POSLTION FOR REMOTE SHUTD0E'i CAPABIllTY FOR WATERFORD 3 To Meet GDC-19 (As interpreted in SRP Section 7.4)
- 1) The design should provide redundant safety grade capability to achieve and maintain hot shutdown from a location or locations, remote from the control room, assuming no fire damage to any required sy' stems and equipmnt and
~
assuming no accident has occurred.
Credit may be taken for manual actuation (exclusive of continuous control) of systems from locations that are reasonably accessible from the Remte Shutdown Panel.
Credit may not be taken for manual actions involving jumpering, rewiring or disconnecting circuits.
2)
The design should provide redundant safety grade capability for attaining subsequent cold shutdown through the use of suitable procedures.
_To Meet Appendix K (ECCS Requirements)
- 3), The design should be such that the manual transfer of control to the remte location (s) should not disable any automatic actuation of. ESF functions while the plant is attaining or maintained in hot shutdown, other than where ESF features are manually placed in service to achieve or maintain hot shutdown.
It is permissible to disable automatic LPCI actuation in this manner only when necessary in order to enabl.e control of the RHR system from the remte location and while operating this system to effect cold shutdown from hot shutdown.
To Meet Appendix R (Fire Protection Requirements)-
4)
The design should provide, as a minimum, non-redundant non-safety grade systems necessary to achieve and maintain hot shutdown from either the control room or i
from a remote location (s) assuming a postulated fire in any fire area, including the control room or the Re. note Shutdown Panel.
Credit may be taken for manual actuation (exclusive of continuous control) of systens fmm locations that are reasonably accessible from the control room or the Remte Shutdown Panel, as applicable. Credit may not be taken for manual actions involving jumpering, rewiring'or disconnecting circuits.

- 5) 'Ti.te d: sign should provide, as a minimum non-redundant'non-safety grade systems e
necessary to ' achieve and maintain cold shutdown from either the control room or from a rerote location (s).. The design should be such that in the event of fire damage in any fire area, systems could be repaired or nade operable within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> if required for cold shutdown.
