Nuclear Decommissioning at Winfrith
Remote Segmentation and Export of the SGHWR Upper Neutron Shield
Winfrith was a 350 acre prototype reactor site for civil nuclear power operating up to nine reactors and numerous other facilities.
James Fisher Nuclear (JFN) working with Magnox have designed and built remotely operated tooling and developed techniques to segment, size reduce, and package the Steam Generating Heavy Water Reactor (SGHWR) Core for long term storage / disposal. The Upper Neutron Shield (UNS), weighing in at approximately 35 tonnes, is one of many items that presents technical challenges associated with this complex redundant reactor which will be the first power reactor to be fully decommissioned within the UK on behalf of the Nuclear Decommissioning Authority (NDA).
There is no ‘on the shelf’ design for this type of project and the solutions developed are innovative applications of modified commercially available equipment supported by bespoke variations of nuclear designs from across the NDA estate.

James Page and Ian Smith
Engineers - James Fisher Nuclear Ltd.
James Page BEng (Hons) CEng MIMechE
A professional within the nuclear industry for 18 years, James joined BNFL in 2001 as a graduate mechanical engineer following his degree course at the University of Newcastle upon Tyne. His early career focused on the delivery of MOX fuel production plant within both the design office at Risley and onsite support office at Sellafield. Whilst at BNFL/Sellafield Ltd James followed the MPDS scheme and was successful in his application for chartership and full membership of the IMechE in June 2006.
Moving to a more senior position at BNS he delivered the detail design of the heavy shield doors for BEP Product Store Comprehensive Import/Export Facility (BEPPS/CIEF) at Sellafield. James then transitioned to a decommissioning role with Magnox at the Trawsfynydd site in North Wales successfully delivering the design and on site removal of ILW from three Ion Exchange Resin storage vaults, a vacuum retrieval system for the Main Sludge Vault and the early installation works for the FEDER project. Following an 8 month role working as a nuclear specialist for the UK governments ‘Civil Nuclear Sharing in Growth Scheme’, James moved to James Fisher Nuclear working on a major project for Sellafield before commencing the role of Engineering Integration Manager for the SGHWR core segmentation project.
The collaborative Magnox and JFN team has now progressed the design to a the point where the full detail design acceptance is expected shortly and the commencement of low risk early onsite works within the SGHWR facility.
Ian Smith MEng(Hons) CEng MIMechE
A mechanical engineer with over 15 years nuclear remote handling experience, Ian has designed manipulators for use in some of the UK’s most hazardous nuclear environments, and has been involved in providing decommissioning solutions to many of the industry’s biggest challenges.
Ian graduated from Loughborough University with a degree in Mechanical Engineering in 2007, before joining James Fisher Nuclear as a Mechanical Design Engineer. He was appointed Engineering Manager in 2015, before adopting his current role of Principal Engineer last year. He became a Chartered Engineer in 2012.
Ian’s early work for JFN included supporting the design and development of equipment to recover isotope cartridges from Pile II at Windscale, stuck fuel recovery equipment for Wylfa and a variety of bespoke manipulators and associated tooling.
Ian has since led a number of multi-disciplinary remote handling and decommissioning projects through their entire lifecycle, including the design and build of a containerised waste retrieval system for Bradwell and the development of a six degree of freedom water hydraulic manipulator used to recover dropped fuel rods in the Magnox Reprocessing facility at Sellafield.
For the last two years Ian has led the team responsible for the development of the remote tooling and deployment platforms to be used to segment the core of the SGHWR reactor at Winfrith.
