摘要

Government regulations require the measuring and reporting of radioactive effluent from nuclear power plants. In addition to effluent reporting based on laboratory analyses, continuous monitoring during a postulated design-basis accident is also required. Wide-range gas monitors for satisfying regulatory requirements for post-accident radiation monitoring typically have been very complex, and costly to operate and maintain. This paper describes recently developed solid-state detectors that can be mounted directly in the vent stack of a nuclear power plant for monitoring gaseous effluent during normal and postulated accident conditions and also for providing real-time isotopic analysis of the gaseous plant effluent. A stack-gas monitor system using these detectors is also described, including anticipated signal levels based on calculations for an actual operating nuclear power plant (a pressurized-water reactor).
