The NDA has announced that Dr Ros Rivaz has been appointed as Chair of the Nuclear Decommissioning Authority, succeeding Tom Smith, whose term as Chair ends on 31 August 2020.
Minister for Business and Industry, Nadhim Zahawi, said:
The UK has unrivalled expertise in nuclear decommissioning, cleaning up the environment, boosting the economy and delivering highly-skilled jobs, so I am delighted by Ros’s appointment as the new Chair of the Nuclear Decommissioning Authority.
Ros is ideally suited to provide the NDA with the leadership to strengthen its culture, build its capabilities, and deliver on its mission safely as we work towards eliminating our contribution to climate change by 2050.
Dr Rivaz said:
I am honoured to accept this role. I have been fortunate to work in some of the most innovative companies in the UK and internationally, in sectors such as engineering, manufacturing and chemicals.
I am to use that experience to support the NDA’s work as it deals with some of the world’s most complex challenges. It is an organisation with a clear vision and strong strategy. I relish the chance to take its mission forward.
Tom Smith said:
It has been a huge privilege to be the Chair of the NDA. The NDA’s work is important to the country as it deals with the UK’s civil nuclear legacy. I wish all the staff of the NDA well. I admire their determination, expertise and sense of public service. And, of course, I also wish Ros every success in her new role.
David Peattie, NDA CEO, said:
I’d like to welcome Ros to the NDA. Our work and achievements is a great source of pride for me and it is fantastic to have her with us. I would also like to pay tribute to our outgoing Chair.
I have greatly enjoyed and valued working with Tom Smith. Together we have brought about significant changes to the NDA’s operating model and culture.
