Radiation tolerant equipment

James Fisher Nuclear (JFN) appreciates that the nuclear environment spans a wide variety of plants and facilities from background radiation and minimal contamination to highly active waste handling facilities. We understand that equipment should be selected and specified in accordance with the local environmental requirements.

JFN has extensive experience in designing and building systems for operations in high radiation environments. Recent experience includes manipulators and tooling including size reduction equipment, mechanical handling systems, camera systems and NDT systems.

Electrical connectors and distributors

To facilitate remote installation and maintenance in highly active environments JFN has developed a wide range of radiation tolerant accessories to service the needs of highly active facilities.

Distribution equipment

JFN provides a range of radiation tolerant electrical distribution equipment working from "clean side" supplies and controls though the shield wall to distribution boxes and on to individual hardware systems. All the equipment is able to be deployed and recovered remotely using a combination of manipulators and cranes. Such equipment has been used in the Vitrification and SDP plants at Sellafield.

Connectors

JFN supply a range of radiation tolerant connectors. The connectors are fabricated from stainless steel with PEEK inserts to give a radiation tolerance of 1000 MRads. The connectors are designed for operation with large power manipulators or master slave manipulators (MSMs) and are "scoop proof" – they are designed to prevent potential damage to pins or sockets due to mishandling during the connection.
