Nuvia wins contract for Dounreay Fast Reactor Residual NaK Removal

Nuvia (UK) has secured a multi-million-pound contract for Dounreay Site Restoration Limited (DSRL) to design, procure, install and commission plant and equipment to remove the residual NaK (Sodium-Potassium) remaining in the Dounreay Fast Reactor’s (DFR) complex piping network.

The NaK is to be removed by using an existing Water Vapour Nitrogen process (essentially steam) that will react with the residue, producing sodium hydroxide, potassium hydroxide and hydrogen. The resultant products will be collected and processed using existing gas filtration systems and the existing Ion Exchange Plant to make them safe for disposal.

The works will be engineered in Nuvia’s design offices, from where the first stage procurement and manufacturing of pipework and equipment will also be managed. Installation and commissioning will be undertaken on the Dounreay site and will be managed utilising Nuvia’s local staff with support from local Caithness and Sutherland supply chain.

The contract underpins Nuvia’s ongoing long-term investment in the region, helping Nuvia to deliver on it’s Community Benefit Plan commitments.

The contract commenced in July 2018, to be delivered over a three-year period.

David Craig, Nuvia’s Dounreay Business Manager said:
This is an important contract win. Over many years Nuvia has a number of decommissioning activities at DFR. We are delighted to continue our relationship. This is an excellent opportunity to pass some of our knowledge and expertise onto the next generation.
