Take steps on SNF and HLW disposal
Matt Bowen
With a new administration and Congress, it is time once again to ponder what will happen—if anything—on U.S. spent nuclear fuel and high-level waste management policy over the next few years. One element of the forthcoming discussion seems clear: The executive and legislative branches are eager to talk about recycling commercial SNF. Whatever the merits of doing so, it does not obviate the need for one or more facilities for disposal of remaining long-lived radionuclides. For that reason, making progress on U.S. disposal capabilities remains urgent, lest the associated radionuclide inventories simply be left for future generations to deal with.
In March, Rick Perry, who was secretary of energy during President Trump’s first administration, observed that during his tenure at the Department of Energy it became clear to him that any plan to move SNF “required some practical consent of the receiving state and local community.”1

The possibility of producing the base load of both electricity and district heat for the Helsinki Metropolitan Area (HMA) utilizing nuclear energy has been investigated since 1968. At every stage of the study, it has been concluded that district heating utilizing nuclear power in combined electricity and heat production is the most economic way of heating the main part of the HMA. The studies have dealt with the economy of energy production and heat transmission as well as nuclear safety. According to the latest results, the optimum of the heat output of a 1000-MW(electric) unit is ∼800 MW if the plant is situated 50 km away from the heat load center. For further studies and realization of the plans, the cities of the HMA and the state-owned power company, the Imatra Power Company, have formed a common company for the nuclear power plant project.
