Magnox work

An installer reports major – and long-lasting – project work with Magnox, particularly in relation to decommissioning security.

Quadrant Security Group (QSG) reports new project work with nuclear management and operations contractor Magnox Ltd, including what is said to be a UK first in decommissioning.

QSG’s existing contract with Magnox Ltd, sees it provide and maintain a range of security systems across Magnox sites, one still generating electricity, besides those undergoing decommissioning. This involves the design, supply, installation and maintenance of integrated systems across the Magnox fleet.

QSG has extended this contract from six to eight Magnox sites, and is also working with the firm to find and test appropriate security for two places on a ‘decommissioning fast track’ that will see them become the first of their type in the UK to move into a ‘Care and Maintenance’(C&M) phase.

How the C&M phase is managed at the two sites, including the security control and management measures employed, is likely to form a nuclear industry blueprint.

Also, QSG is also working on a £1.3m ‘site separation’ project for Magnox. Some sites operate on a twin station basis, historically sharing a central security system. As the sites move further towards their end of life, separating such systems becomes essential. The first separation project is due for completion in June 2013.

Magnox, the generic term, is the name of the first generation of commercial nuclear power stations to operate in the in the world, 11 of which are now in various stages of decommissioning under the auspices of the Nuclear Decommissioning Authority (NDA). One is still operational. Operating under contract for the NDA, Magnox Ltd is responsible for the operation and decommissioning of the eleven sites.

As for taking sites through the decommissioning process in a highly-regulated sector, QSG points to over 20 years’ experience in the nuclear sector, and its Nuclear Skills accreditation from the National Skills Academy. During the next 10 years, the Nuclear Decommissioning Authority (NDA) expects all Magnox-type sites to have been defueled and most of them to have entered the C&M phase, reaching final site clearance between 2080 and 2120.
