The SGLM 202K has been designed to detect and quantify leaks between the primary and the secondary circuits of a steam generator in a nuclear power plant. It operates on the principle that radioactive nitrogen produced in the reactor core during operation crosses into the secondary circuit through a steam generator tube.
• Spectrum stabilization against temperature and aging drifts. • 16 selectable windows over the range covered. • 1024 channels analysis. • Available with or without display and local signaling. • Seismically qualified. • More than 800 SGLM channels in operation worldwide.
The SGLM 202K can only withstand temperatures between -5°C to +55°C .
The NaI(TI) detector for the SGLM 202K is enclosed inside a 2 p / 5 cm (2”) thick lead shielding to ensure protection against the ambient gamma background noise. As a result, this detector has no thermal insulation.
