Description
The GEMS-401 system is designed for measurement of noble gases and sampling of particulates and iodine after the LOCA accidents. The air sample is taken from the containment of nuclear facilities.
The main components are:
- heated stainless steel routes with valves to distribute the measured air,
- two parallel shielded chambers for sampling particulates and iodine (each chamber is equipped with a particulate filter and an iodine cartridge), including dose rate detectors,
- the NGD-14 detector for measuring the volume activity of radioactive noble gases,
- redundant pumps,
- a purge system with a separate pump,
- a processing and display unit with 10 “touch screen,
- a steel frame, ensuring seismic resistance of the system.
Product design and specifications are subject to change without prior notice or obligation.
