NUREG-1537, Part 2 - NRC

CHAPrER 10
Areas of review should include the following:
Design of the experimental faicility: the facility design aspects to contain or
withstand any postulated pressure pulse, temperature change, or reactivity
effect to preclude any inadvertent primary coolant leakage or facility
collapse; facility materials of fabrication and compatibility of materials with
projected radiation and chemistry requirements; physical size, including all
dimensions; and simplified engineering drawings or schematics, if used,
especially for more complex facilities.
* Incorefin-reflector experimental facilities, including important design and
operating parameters and specifications: location of the facility in relation
to the core, safety systems, core support, neutron detectors, coolant system
components, and other in-pool structures; and reactivity effects of these
facilities.
* Features of the experimental facility that prevent interference with safe
reactor shutdown or with adequate core cooling.
* Radiological considerations associated with the design and use of the
experimental facilities: generation of radioactive gases (including
argon-41), release of fission products or other radioactive contaminants,
and exposure of personnel to neutron and gamma beams, in relation to any
ficility-related technical specifications; direct radiation streaming from the
experimental facilities and the effect of scattered (sky shine) radiation; any
radiation monitors specifically designed and placed to detect experiment
radiation and to monitor personnel; and any physical restraints, shields,
beam catchers or beam stops, temporary and permanently installed, used to
restrict access to radiation areas associated with experimental facilities.
* Experiment safety system and the fimctional interface between this system
and the reactor protection system: the experimental facility safety
instrumentation, including the location and finction of sensors, readout
devices, and scram or interlock capabilities, and all permanently installed
instrumentation and control systems.
* The need for experiment cooling and the source of coolant and any
dependence on or interaction with the reactor coolant system. The
reviewer should refer to Chapter 5, "Reactor Coolant Systems," of this
review plan.
* Proposed technical specifications for the experimental facilities.
