180 NAC 9-007. PARTICLE ACCELERATOR CONTROLS AND INTERLOCK SYSTEMS

007. PARTICLE ACCELERATOR CONTROLS AND INTERLOCK SYSTEMS. Particle accelerator control and interlocks must meet the following requirements. 007.01 CONTROL CONSOLE. Instrumentation, readouts and controls on the particle accelerator control console must be clearly identified and easily discernible. 007.02 ENTRANCE. Each entrance into a target room or other high radiation area must be provided with a safety interlock(s) that shuts down the machine under conditions of barrier penetration. 007.03 MANUAL RESET. When a safety interlock system has been tripped, it must only be possible to resume operation of the accelerator by manually resetting controls at the position where the safety interlock has been tripped, and lastly at the main control console. 007.04 INDEPENDENT CIRCUIT. Each safety interlock must be on a circuit which must allow its operation independently of all other safety interlocks. 007.05 DESIGN. All safety interlocks must be designed so that any defect or component failure in the safety interlock system prevents operation of the accelerator. 007.06 CUTOFF SWITCH. A scram button or other emergency power cutoff switch must be located and easily identifiable in all high radiation areas. The cutoff switch must include a manual reset so that the accelerator cannot be restarted from the accelerator control console without resetting the cutoff switch.
