This bill proposes changes in Minnesota's laws regarding the expansion of nuclear power. Specifically, it allows the state to issue certificates of need for the construction of new small modular nuclear reactors, as long as these reactors have a maximum capacity of 300 megawatts. This is a modification to the current rule that generally prohibits the building of new nuclear power plants. Additionally, any applications for prolonging the use of existing nuclear facilities by adding more storage for spent nuclear fuel must evaluate the long-term environmental and operational impacts.
