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 development of district heating systems in Poland up to 1990 is characterized with particular reference to the combined generation of heat and electrical energy in fossil-fired and nuclear heat-and-power plants. The proposed method of an economic evaluation of nuclear heat-and-power schemes consists in comparing them with the equivalent fossil-fired plants and minimizing the total annual costs of heat energy generation. Hence, the optimum value of the so-called combination factor α can be obtained, this factor being defined as the ratio of heat output at the steam turbine outlets to the maximum heating load of the whole heat-and-power plant. As an example of the optimization procedure, three particular values of the maximum heating load Qmax in given areas are considered: Qmax = 1000, 1500, and 2000 MW, and in each case the optimum a values are determined.
