A device used to provide information on the flow of nuclear or
other material, or on the status of a nuclear facility or
equipment. Examples of monitors include:
- Core discharge monitor (CDM) - A
radiation monitoring system that monitors the charging and
discharging of irradiated fuel bundles to and from the core of an
on-load refuelled power reactor.
- Spent fuel bundle counter - A
radiation monitoring system that counts irradiated fuel bundles as
they are discharged to the spent fuel storage bay of an on-load
refuelled power reactor.
- Reactor power monitor - Neutron
monitoring system placed outside the reactor biological shield to
monitor the power level of the reactor.
- Radiation passage monitor - A device
used to detect, by the radiation emitted, the passage of nuclear
material through openings in a containment. For example,
dosimeters, such as thermoluminescent dosimeters, can be used as
'yes/no monitors' to confirm the absence of irradiated fuel
removals.
