Sweco has signed an agreement to acquire Platom, a Finnish company providing technical consultancy across the full life cycle of nuclear operations. The acquisition makes Sweco the leading nuclear consultancy in Finland and also strengthens Sweco's European capabilities in this growing sector.
Platom is an expert company specialising in the nuclear industry, where it serves nuclear operators in the fields of nuclear and radiation safety, licensing, nuclear projects and nuclear technology. The company has more than 25 years of experience in expert services in the nuclear industry and employs approximately 30 specialists.
"I am excited to welcome Platom's specialists to be an important part of Sweco, which is one of Europe's most experienced consultancies in nuclear infrastructure. Platom is Finland's leading consultancy in the nuclear industry, and their expertise strengthens Sweco's competitiveness both in lifecycle projects related to traditional nuclear power and in new-build nuclear power projects, such as small modular reactors (SMRs)," says Thomas Hietto, Business Area President of Sweco in Finland.
As momentum across the nuclear sector continues to build, the industry is working through factors such as capital requirements, regulatory and permitting timelines, and supply-chain scaling. The rising investment is also driving strong demand for specialised engineering, technical and advisory expertise across Europe.
"Expertise in nuclear projects is highly sought after by our clients, not only in Finland, but across Europe. Sweco has extensive experience from nuclear projects in various countries, including Sweden, Finland, Belgium, Lithuania and Norway. These projects are complex and require specialist skills in a range of fields over long periods of time, and through the addition of Platom, Sweco has further strengthened our capabilities to support clients in this sector," says Thomas Hietto.
