He has more than 40 years experience in the nuclear sector and is a specialist in waste management and decommissioning. Research is vital – and we need more of it Let me start with a little personal refl ection. Given the scale of UK liabilities (NDA this has been immensely improved by the I started my professional career with 10 liabilities alone are currently estimated at Board and the work of the Nuclear Waste years nuclear energy research. Many around £50 billion in discounted terms), Research Forum. years and roles later I spent 15 years in anything that can be done to improve This new approach for the UK is in line senior positions in waste management and safety and environmental performance and with the conclusions of last year’s hard- decommissioning. So for me it was a great reduce costs is extremely benefi cial. hitting House of Lords report, which pleasure to be invited to chair the NDA’s Research and Development is the key to recommended that more must be done to Research Board, allowing me to bring improvement in each of these areas, and develop a long-term strategy for nuclear these two career ends together. Not only this impacts far more than just clearing R&D, including a roadmap to close that, of course, but R&D in this area is so up the past.

In this context it is important to emphasise We are fully aware of this and are keen that the Research Board, while focused to inspire new blood into R&D, building on the NDA mission, now also takes a a generation of experts who will play wider view across the UK as a whole to an important role in ensuring that the help ensure alignment.

When, after my second period on the UKAEA Board, I left the UK to work with the OECD Nuclear Energy Agency in Stan Gordelier, former Head of the Paris, there was no such linkage. On my Nuclear Development Division of the return, it is a great pleasure to see how OECD Nuclear Energy Agency “Building a generation of experts who will play an important role in ensuring that the UK remains a vital player in the global nuclear industry” INSIGHT OCTOBER 2012 3 Spotlight on Research and Development Sellafield excited by remote possibilities The challenges at Sellafi eld are numerous, complex and hazardous, with environments that often rule out sending in a human taskforce. Instead, solutions must be developed successfully used in both production Dr Melanie Brownridge, NDA Head that allow machines to do the dirty plants and decommissioning operations. of R&D, said: “These examples work and ensure workers remain safe. Typical examples include remotely demonstrate the importance of robust Wherever possible, the approach is to operated vehicles for surveying work, technical underpinning to deliver use tried and tested technology adapted master-slave manipulators (hand-like decommissioning.
