NUREG-1537, Part 2 - NRC

REAC =COOLAT SYSTEM
* The secondary coolant system design should provide for any necessary
chemical control to limit corrosion or other degradation of the heat
exchanger and prevent chemical contamination of the environment.
* . The applicant should identify operational limits, design parameters, and
survillances to be included in the technical specifications.
Review Procedires .
The reviewer should verify that all reactor conditions, including postulated
accidents, requiring transfer of heat from the primaiy coolant system to the
secondary coolant system have been discussed. The reviewer should verify that
the secondary coolant system is capable of removing and dissipating the amount of
heat and the thermal power necessary to ensure fuel integrity. The reviewer
should also confirm the analyses of secondary coolant system malfunctions
including the effects on reactor safety, fuel integrity, and the health and safety of
the public.
Evaluasion Findngs
This section of the SAR should contain sufficient information to support the
following types of conclusions, which will be included in the staffs safety
evaluation report:
Design features of the secondary coolant system and components will allow
the transfer from the primary coolant system the necessary reactor heat
under all possible reactor conditions.
* Locations and design specifications for secondary coolant system
components ensure that malfunctions in the system will not lead to reactor
damage, fuel failure, or uncontrolled release of radioactivity to the
'environment.
* Secondary coolant system instrumentation and controls are designed to
provide all necessary functions 'and to transmit information on the'
operating status to the control room.,,
* The secondary coolant system is designed to respond as necessary to such
postulated events as a loss-of-pnimary-oolant accident and a loss of forced
coolant flow in the primazy coolant system.
* The technical spediflcations, including testing and surveillance, provide
reasonable assurance of necessary secondary coolant system operability for
normal reactor operations.
