ENCLOSURE A The following questions are based on the applicant's response dated December 8, 1981 to the staff position on remote shutdown that was transmitted to the applicant on August 17, 1981.
(1)
The staff is questioning the use of the ADS valve controls located in the upper and lower relay rooms since they share a
common HVAC system with the control structure.
We request
" additional information concerning procedures 'for access to these areas during a control room evacuation.
These pro-cedures should include a method of isolating either of these relay rooms from the control structure HYAC system or of isolating the control room from the HYAC system and a
discussion of the smoke detectors in. the relay rooms.
(2)
The applicant's response to our position 'was incomplete.re-garding instrument indicators needed for hot and cold shutdown.
We require. that a single failure analysis be provided for these indicators along with the locations for the alternate indications.
(3)
The Redundant Path shown in Attachment A tabulates the systems or functions required to achieve a redundant or diverse method of shutdown where the controls and indicators are not necessarily on the Remote Shutdown Panel.
- However, we require that locations be shown for the redundant systems or functions and these locations must be reasonably accessible from the Remote Shutdown Panel.
(4)
Provide an analysis for using the Reactor Core Isolation Cooling (RCIC)
System to reduce the reactor pressure.
This analysis should be per-formed with the use of the RCIC system as a path for reducing reactor pressure during remote shutdown assuming SRVs and the ADS to be un-I'vailable, and should include verification that the RCIC turbine steam flow is sufficient to reduce reactor pressure to achieve cold shutdown.
The time to reach cold shutdown should also be provided.
