Process-Monitoring Instrumentation

Process monitoring instrumentation refers to those systems outside the neutron-monitoring group which indi­cate, record, and control all operational systems within a nuclear reactor facility A channel includes the primary sensor, the interconnecting conductors, the measuring circuit, and displays The primary sensors are located at a point in the process system The measuring-circuit instru­mentation (amplifier, recorder, power supply, etc ) is […]

Test — and Inspection-Equipment Engineering

Test equipment and measurement systems are generally sufficiently complex to require a special engineering group to provide measurement hardware The requirement for test equipment is set by the quality-control engineer. The test — and inspection-equipment engineers, who are basically design oriented, take the quality-control engineer’s require­ments and provide the hardware that will be used by the process-control engineer in implementing […]

Quality Control at the Reactor Site

(a) Verification of Condition on Receipt. All nuclear instruments, associated panels, sensors, wire, and coaxial cable should be inspected by Receiving Inspection for signs of damage on receipt at a reactor site. Receiving documents should then be checked to verify that the requirements of the purchase requisition have been fulfilled. The purchase requisition will contain specifications or refer to specifica­tions […]
