Small Modular Reactor (SMR) technology is presented as part of Europe’s energy transition and decarbonization efforts, but its implementation faces obstacles across various countries. In Romania, despite being an early adopter with a partnership for six SMR units at Doicești, the project has faced criticism regarding high costs and feasibility studies. There are also suspicions surrounding potential real estate interests in the chosen site. Bulgaria is exploring SMR implementation through external evaluations, though concrete steps remain slow, and one state-owned company’s plans have been complicated by financial issues with its partner. Another Bulgarian entity is developing a joint venture to explore BWRX-300 technology, but regulatory approval processes are expected to be lengthy and complex. Greece currently lacks a national strategy for SMRs; while the government views them as a potential long-term decarbonization complement, environmental groups criticize them as unproven technology with unresolved issues regarding cost, waste, and safety. In Czechia, despite a strategy to replace aging coal plants with SMRs by 2033, practical development appears unfeasible due to high costs, lack of experience, and regulatory hurdles. France has strategies involving SMRs and Advanced Modular Reactors (AMRs), such as the Nuward project, but implementation is uncertain; while many projects are in technical development, none have reached operational construction, largely due to financing gaps and the need to transform numerous small projects into bankable ones. Conversely, Austria maintains a strict legislative ban on nuclear energy production or use, including SMRs, despite some public opinion shifting towards greater energy security concerns.

PULSE is an initiative for cross-border collaborative journalism in Europe co-funded by the European Commission under Grant Agreement n. PO 4500158093.

PULSE is an initiative coordinated by OBCT that has been promoting intensive journalistic cross-border collaborations in Europe since 2024. Its main aim is to help strengthen the European public sphere by reporting on and telling stories from new and diverse perspectives.

At the heart of PULSE are 10 leading national news outlets (Delfi – Lithuania, Deník Referendum – Czechia, Der Standard – Austria, EfSyn – Greece, El Confidencial – Spain, Gazeta Wyborcza – Poland, HotNews – Romania, HVG – Hungary, Il Sole 24 Ore – Italy, Mediapool – Bulgaria) and three transnational organisations, including OBCT , n-ost and Voxeurop .

Additional outlets and journalists are involved as associate partners, including EUobserver , Føljeton (Denmark), H-Alter (Croatia), Levila (Estonia), Rubryka (Ukraine), and The Journal Investigates (Ireland).

PULSE is driven by a sort of virtual transnational newsroom made up of journalists from all the publications involved. It collaboratively produces new journalistic content on European issues on a daily basis, coming in many different languages. The editorial output amounts to over a thousand publications per year, mostly in article form.

PULSE also runs 4 thematic networks open to any European journalist interested in crucial issues such as EU enlargement, relations between the EU and other global powers, the EU’s green transition, or media and the information society. These networks function as online communities and periodically publish calls for pitches.
