James Fisher Nuclear has many years of experience in reactor segmentation and packaging and is widely recognised as a world leader in this important discipline.
James Fisher Nuclear (JFN) has cemented its position as a leading project and technical integrator, taking on large scale multi-discipline projects. With a focused decommissioning mindset and technical expertise built over many years decommissioning success, JFN has become a supplier of choice and industry leader in this complex, but vital, specialism.
Magnox SGHWR Winfrith
JFN is currently working to decommission The Magnox Steam Generating Heavy Water Reactor (SGHWR), located near Winfrith in Dorset. This is the first commercial reactor to be decommissioned in the UK. The ultimate goal for Magnox is to be able to return the site to publicly accessible heathland.
JFN's task is to formulate 8 distinct but integrated decommissioning campaigns supported by a suite of over 40 different MOTS and COTS tools, manipulators, cranes and robots, that will remotely dismantle the reactor and safely package and dispose of the waste through 3 defined waste streams.
The first reactor to be decommissioned from within the NDA estate was the Windscale Advanced Gas-cooled Reactor (WAGR), with JFN playing a significant role in the decommissioning of the reactor internals, the pressure vessel and insulation. Optioneering & feasibility Studies were carried out by JFN, with design and manufacture of tooling and electrical control systems and the development of systems and techniques. This was supported by test rigs, trials and comprehensive training to ensure that once on site the project operated, safely and efficiently through to successful completion.
Reactor decommissioning is a complex and involved process, where nothing can be left to chance and safety is paramount. JFN delivers tried and tested solutions to complex decommissioning questions. So you can be confident our specialist engineering teams will deliver the most economic and advantageous solutions for the nuclear decommissioning industry in a safe, environmentally and socially responsible manner.
