Description
The N16M-504 monitor is designed to measure the volumetric gamma activity of nitrogen-16 and quantify leaks from the primary to secondary circuits in the steam generators of nuclear power plants.
During reactor outages or operation at low thermal power levels, the total gamma activity of radionuclides in the main steam line is measured. Nuclide-specific activities can also be measured and displayed.
Product design and specifications are subject to change without prior notice or obligation.
