NUREG-1537, Part 2 - NRC

-.... - . INSTRUMENTATION AND CONTROL SYSTEMS
Reactor operation should be prevented and not authorized without use of a
key or combination input at the control console.
Review Procedures
The reviewer should coordinate the review of this section with all other applicable
chapters of the SAR because the control console and other display instruments in
the reactor control room could be linked to numerous systems and subsystems in
the reactor facility. The reviewer should compare the design bases and functional
requirements of other reactor systems with those for the control console
equipment. The reviewer should also compare the design of the console system
-with the acceptance criteria. The reviewer should study the arrangement of
parameter displays, control devices, and the planned operator station to determine
whether the operator can quickly understand information and take proper action.
The reviewer should obtain the assistance of experts in the I&C Branch to review
computer systems. The reviewer should note the discussion in the format and
content guide about digital operator information display systems or operator aids.
Evaluation Findings
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:
The applicant has shown that all nuclear and process parameters important
to safe and effective operation of the (insert name offacility) non-power
reactor will be displayed at the control console. The display devices for
these parameters are easily understood and readily observable by an
operator positioned at the reactor controls. The control console design and
operator interface are sufficient to promote safe reactor operation.
d The output instruments and the controls in the control console have been
designed to provide for checking operability, inserting test signals,
performing calibrations, and verifying trip settings. The availability and use
of these features will ensure that the console devices and subsystens will
operate as designed.
* - The annunciator and alarm panels on the control console give assurance of
the operability of systems important to adequate and safe reactor operation,
even if the console does not include a parameter display
* The locking system on the control console reasonably.ensures that the
reactor facility will not be operated by unauthorized personnel.
