The Radiation Monitoring System (RMS) at the NIST Center for Neutron Research (NCNR) Reactor (National Bureau of Standards Reactor – NBSR) has demonstrated reliability issues due to outdated hardware and lack of vendor support. The existing radiation monitors communicate to a controller in the control room, which then displays an LCD segmented display to operators. If the value is over its pre-defined threshold, the machine actuates an annunciator to indicate an unsafe condition. Over time, multiple RMS devices have gone out of commission, being unable to communicate with the centralized controller, and localized monitors had to be used to monitor area radiation safety. The original manufacturer of the system has since gone out of business and attempts to repair and replace broken components have been fruitless. It is due to these reasons that a new system has been engineered using modern control and communication systems integrated into the NBSR Control Console Upgrade.
