**Studsvik AB and ReNu Industries Inc. will adapt Studsvik’s inDRUM technology for
radioactive waste treatment to Japanese conditions, with the aim of building a pilot
plant in Fukushima. Studsvik’s Japanese subsidiary, Studsvik Japan, Ltd., and ReNu
signed an agreement on technical advisory services at Studsvik’s headquarters in
Nyköping on 21 October 2026.**

NYKÖPING, Sweden, Oct. 23, 2026 /PRNewswire/ — Under the agreement, Studsvik will
provide ReNu with technical information and advice on design conditions for a Japanese
version of inDRUM. ReNu will design a pilot plant adapted to Japan’s seismic and
regulatory requirements and to the characteristics of the waste to be treated.

The partnership is the first step in the model Studsvik has chosen for taking inDRUM
to international markets. Studsvik will build and operate its own inDRUM facilities
in Sweden, while abroad it will license the technology and work with local partners
that design, build and operate the plants.

inDRUM, developed and patented by Studsvik, treats radioactive waste inside sealed
drums. Each drum is placed in a treatment unit and heated under a nitrogen blanket,
which removes free liquids, breaks down organic material and leaves a stable residue
suitable for long-term storage and disposal. Because the drums are neither opened
nor sorted, worker exposure and manual handling are minimised. For spent ion-exchange
resins and similar wastes, volume can be reduced by up to 90 per cent. Studsvik 
operates a full-scale inDRUM demonstration facility in Nyköping and is advancing
the adoption of inDRUM for the treatment of radioactive waste from the European 
Spallation Source (ESS) in Lund.

Decommissioning of the Fukushima Daiichi Nuclear Power Plant is expected to take
30–40 years, and the decommissioning of other nuclear power plants in Japan is gathering
pace. At the same time, Japan is restarting reactors shut down after 2011, which
increases the need for waste treatment and for other services Studsvik provides.
Reducing and stabilising the volume of radioactive waste is a long-term challenge
in this work.

ReNu has been awarded up to JPY 700 million (approximately USD 4.4 million) under
the Subsidy for Projects Promoting Practical Development for Regional Reconstruction,
implemented by Fukushima Prefecture under the Japanese Government’s Fukushima reconstruction
initiative, to develop a radioactive waste treatment pilot plant in Fukushima. ReNu
aims to establish the basic design conditions for the Japanese version of inDRUM
during fiscal year 2026, which ends in March 2027, and, subject to the necessary
agreements, to complete the pilot plant in fiscal year 2028.

Building on the Fukushima project, Studsvik and ReNu will explore deploying inDRUM
elsewhere in Japan and in Asia, as well as broader cooperation in nuclear engineering,
including fusion.

"Fukushima will need radioactive waste treatment for decades. ReNu is based in Okuma,
the town that hosts the plant, and brings the local knowledge needed to adapt inDRUM
to Japanese conditions. Fukushima is our starting point in Japan and in Asia," says
Karl Thedéen, President and CEO, Studsvik.

"Studsvik Japan will coordinate the Studsvik Group’s experts and support ReNu as
it develops the Japanese version of inDRUM," says Masatoshi Yamasaki, President 
and Representative Director, Studsvik Japan.

"Decommissioning Fukushima requires technology proven around the world, re-engineered
to fit Japan’s regulations and site conditions and implemented with local hands.
Through our technical collaboration with Studsvik, ReNu will adapt inDRUM to Japanese
regulatory and site requirements. We intend to build on our experience in Fukushima
to pursue opportunities elsewhere in Japan and overseas," says Ryohei Takahashi,
CEO, ReNu Industries Inc.

The agreement is not expected to have a financial impact of such materiality that
it significantly affects Studsvik Group’s results during 2026–2027.
