Platom is an expert company specializing in nuclear, serving nuclear operators in the fields of nuclear and radiation safety, licensing, nuclear projects and nuclear technology. The company's expertise covers all stages of the life cycle, from uranium recovery to the treatment and final disposal of spent fuel and radioactive waste. Platom has more than 25 years of experience in expert services in the nuclear industry and employs over 30 specialists.

With the acquisition, Sweco's services will be expanded, especially with expertise in nuclear technology, licensing and radiation safety.

"Platom is Finland's leading expert organization in the nuclear industry, and their expertise strengthens Sweco's competitiveness in both lifecycle projects related to traditional nuclear power, and in new-build nuclear power projects such as modular small nuclear power plants. Together, we can provide our clients with an even more compelling service offering that combines Platom’s expertise in nuclear and radiation safety with Sweco’s extensive and diverse engineering resources,” says Tuomas Salminen, Division Director at Sweco.

”In the nuclear energy sector, projects are demanding and require a wide range of experience. Sweco’s extensive expertise, international network, and strong brand in Northern Europe open new opportunities for Platom in international nuclear plant projects," says Kirsi Hassinen, CEO of Platom.

As a result of the acquisition, Platom has been transferred to Sweco's ownership. According to current estimates, the consolidation into Sweco will take place at the end of 2026, when Platom's experts will become part of Sweco's Industry and Energy Division.
