Norway’s Halden Kjernekraft said on Monday it has submitted a formal proposal to begin studies for a nuclear power plant and associated waste storage facility in the town of Halden, marking the first formal step in Norway’s evaluation of domestic nuclear energy.

The submission to the ministry of energy outlines a study program to assess the feasibility, benefits, and potential risks of building a nuclear power plant capable of producing up to 10 TWh annually, requiring about 1,200 MW of installed power and equivalent to the needs of roughly 640,000 households.
