Former National Nuclear Laboratory Account Director heads up new technology company at Rawwater

Business News

 

Kat Lennox, previously employed as account director with the UK’s National Nuclear Laboratory (NNL), has joined Rawwater Applied Technology Ltd as managing director.

A new company within the Rawwater Group, Rawwater Applied Technology Ltd has been established to further exploit the capabilities of the group’s specialist metal alloy seals and application techniques for use in nuclear decommissioning, as well as in other industry sectors.

“This is an incredibly exciting time at Rawwater,” comments group managing director, Professor Robert Eden PhD. “Having successfully created the world’s first ‘anticipated’ 3,000-year-life Bureau Veritas-certified metal seal for oil and gas reservoir plugging and abandonment, we identified further opportunities for our proprietary, low-melting-point bismuth alloys in nuclear decommissioning. Through a programme called Molten Metal Manipulation (M3), we went on to develop a range of alloy classes and application techniques for a host of sealing challenges.

“Such an important technological development required an individual with the necessary skills to convey the capabilities of our M3 programme to both the nuclear sector and wider industry. Having worked with Kat Lennox over a number of years, I knew immediately that she was the right person to take up the mantle and lead Rawwater Applied Technology Ltd.”

Unique perspective of sector

“I am delighted to bring my knowledge of the international nuclear industry to Rawwater,” adds Kat Lennox. “At NNL, I worked with organisations from around the globe on a range of waste management and decommissioning activities. I believe I offer a unique perspective into the requirements of those involved in nuclear decommissioning and the challenges they face. As managing director of Rawwater Applied Technology Ltd, I will apply my nuclear industry expertise to the development, commercialisation and exploitation of the Rawwater Group’s innovative and inspiring sealing technologies for the energy, nuclear decommissioning and high-risk industrial sectors.”

Supporting decommissioning challenges at Sellafield

Rawwater’s specialist M3 alloy seals are being adapted to support decommissioning challenges at the UK’s Sellafield nuclear site in Cumbria. Tokyo Electric Power Company (TEPCO) is also exploring their use across its nuclear facilities. Rawwater M3 alloys can seal large openings or fill micron-sized cracks or pores, preventing fluid leakage. Applied underwater or in the air, M3 alloys can stabilise structures, pipework, flanges, gaskets and other seals. They can be tailored to expand, contract or remain neutral upon solidification, offering reduced recovery costs and extreme longevity.

Rawwater made the transition into the nuclear sector through Sellafield’s Game Changers programme. Game Changers is an innovation programme designed to find solutions and develop technologies to overcome some of the most complex challenges facing the nuclear industry. The programme is delivered by NNL and FIS360, specialists in supporting innovative technologies from concept to commercial production.
