Self-check

The safety principles and criteria used ia the design and constmction of the faciUties which implement the nuclear fuel cycle are analogous to those which govern the nuclear power plant. The principles of multiple barriers and defense-ia-depth are appHed with rigorous self-checking and regulatory overview (17,34). However, the operational and regulatory experience is more limited. 

Small monobloc burners usually have a proprietary control box/photo cell amplifier system. Larger burners may have a dedicated system specific to the application and may utilize self-checking photocell systems.

Some important gas and vapor detection system features to consider when selecting a system are self-checking, auto-calibrating or self-diagnosing capabilities with sensor out-of-service, or malfunction alarming. 

Error checking The complementarity of shape and electrostatic field of subunits constituting the assembly forms the basis for the recognition process. It provides for self-checking and excludes defective subunits thus correcting occasional synthetic errors.

FIDs are used to measure total hydrocarbons at low concentrations such as for pollution, leakage, or safety monitoring. In the FID analyzer, the H2 flame ionizes the carbon atoms, and the resulting ionic current is an indication of the hydrocarbon concentration. In microprocessor-controlled hydrocarbon analyzers, up to eight channels can be obtained for simultaneous analysis of eight samples. These units also have the capability for remote calibration and automatic self-checking.

System self-checks and enumerates hardware resources. Each machine has a different startup routine, called the POST (power on self-test), which is executed by the commands written to the motherboard of the computer. Newer Plug-and-Play boards not only check memory and processors, they also poll the systems for other devices and peripherals.
