According to the agreement, Studsvik will design and license two advanced facilities for handling radioactive waste. One is based on Studsvik's patented inDRUM technology for managing and reducing the volume of contaminated waste, while the other consists of an interim storage facility with an associated pool for handling intermediate-level waste. The construction and operation of the facilities at Studsvik are contingent upon additional agreements being signed at a later stage.

-        Following the completion of feasibility studies, we have decided to move forward with Studsvik in developing inDRUM and interim storage solution. Studsvik will thereby be a key partner for managing the waste generated at our facility. For example, the inDRUM technology can reduce the volume of certain types of waste by up to 90%. This not only reduces our future environmental impact but also our final disposal costs, says
Helmut Schober, Director General of ESS.
 

-        We are happy and proud that ESS has chosen us as a partner to safely and efficiently manage their radioactive waste. Our new inDRUM technology is generating great interest worldwide, and being selected by ESS strengthens our position in this important field, says Karl Thedéen, CEO of Studsvik.

The order is not expected to have a financial impact of such materiality that it significantly affects Studsvik Groups results during 2025.
