NWS appoints Seth Kybird as Interim CEO
Nuclear Waste Services (NWS) has announced that Seth Kybird has been appointed as Interim Chief Executive Officer (CEO) of NWS. He succeeds Corhyn Parr who has led NWS as CEO since its formation in 2022.
Seth will take on the role on 1 April, and joins NWS on an 18-month secondment from Nuclear Transport Solutions (NTS).

NWS chair Liz Peace said:
“I am so pleased that Seth is taking on the role of NWS CEO. He has an outstanding track record of leading and developing organisations.
“His experience at Nuclear Transport Solutions will be hugely valuable and means that he’ll be able to hit the ground running as we continue to deliver our vision to make nuclear waste permanently safe, sooner.
“I also want to offer my thanks to Corhyn Parr for her contribution to NWS and for her outstanding leadership. As NWS’ first CEO, Corhyn has played a vital role in establishing NWS since its formation in 2022, and its many significant achievements since then.”
NDA Group CEO David Peattie said:
“I am delighted that Seth is stepping into the role of NWS CEO. During his tenure as NTS CEO, Seth has been a key figure in the NDA group’s leadership team. His extensive experience and knowledge will be invaluable in leading NWS. I want to extend my thanks to Corhyn and wish her all the best as she embarks on new challenges.”
Seth Kybird said:
“It is a huge privilege to be joining NWS as CEO.
“NWS plays a vital role in protecting people and the environment today as well as taking responsibility for future generations. I’m looking forward to working with NWS colleagues, our stakeholders, and communities and building on successes and progress in priority areas, such as the safe operation of the Low Level Waste Repository in Cumbria and delivery of a Geological Disposal Facility.”
Seth Kybird has been CEO at NTS since its formation in 2021. Before becoming CEO at NTS, Seth was Managing Director of International Nuclear Services. He is also a former strategy consultant and chartered accountant, having previously worked at NDA, KPMG, and Deloitte.
Supported by NWS, the nuclear industry already safely manages radioactive waste – and we will enable the UK Government’s net zero ambition by preparing to safely manage future waste.
NWS is part of the NDA group, which has a mission to safely, securely and sustainably decommission the UK’s oldest nuclear sites, leaving them ready for their next use.
