Summary

Vattenfall Advances Nuclear

Vattenfall is progressing with plans for new nuclear reactors at the Ringhals site, considering GE Vernova and Rolls-Royce SMR as suppliers.
The project targets a capacity of 1,500 MW, utilizing either five BWRX-300 or three Rolls-Royce SMRs, the first nuclear construction in Sweden in over 40 years.
Vattenfall highlights the cost benefits and logistics of small modular reactors (SMRs) due to their simplified designs.
Upcoming actions include applying for state risk-sharing and finalizing supplier selection, with a potential for an additional 1,000 MW capacity.

Summary

Blykalla Innovates SMR

Blykalla and the Research Institutes of Sweden are collaborating to advance lead-cooled small modular reactor (SMR) technology for energy-intensive industries.
The SEALER reactor aims for criticality by 2029 and plans to deploy up to 1,000 SMRs by 2050, producing 500 TWh of clean energy annually.
A partnership with Norway's Institute of Energy Technology focuses on enhancing remote SMR management systems.

History

Historical Context

In 1980, Sweden's Riksdag voted to phase out nuclear power, aiming for a complete shutdown by 2010. This decision led to a significant decline in reactor construction. However, Vattenfall's recent plans for new reactors at Ringhals, targeting 1,500 MW, signal a shift towards small modular reactors (SMRs), which could help meet Sweden's clean energy goals by producing 500 TWh annually by 2050.
