R981/C981 System Camera for Nuclear Surveillance

Description

Mirion Technologies is the world’s most experienced supplier of large turnkey television surveillance systems to the world’s nuclear industry. Major multi-camera radiation tolerant system installations are an essential part of the process monitoring requirements for nuclear power stations and waste handling facilities. New safety requirements relating to plant life extensions and new power plant construction demand the use of television systems to continuously monitor machinery and key plant areas within secondary containment.

The R981/C981 camera range has been specifically designed to suit these large multi-camera configura­tions. Alternatively, single camera channels can be supplied as ideal inspection and surveillance tools.
