Swedish utility Vattenfall announced today it will be starting work on a pilot study on the feasibility of deployment of at least two small modular reactor (SMR) units at the site of the Ringhals nuclear power station.

Vattenfall said the study is focusing on Ringhals in southern Sweden because more electricity generation is expected to be needed in those areas. Two reactor units are currently in commercial operation at Ringhals-3 and -4.
