DOE launches UPRISE to boost nuclear capacity
The Department of Energy’s Office of Nuclear Energy has launched a new initiative to meet the government’s goal of increasing U.S. nuclear energy capacity by boosting the power output of existing nuclear reactors through uprates and restarts and by completing stalled reactor projects.
UPRISE, the Utility Power Reactor Incremental Scaling Effort, managed by Idaho National Laboratory, is to “deliver immediate results that will accelerate nuclear power growth and foster innovation to address the nation’s urgent energy needs,” DOE-NE said in its announcement.

A class of discontinuous finite element methods (DFEMs) is proposed for spatially discretizing the SN transport equation in multidimensions. Mesh cells are first subdivided into simplexes. Equations for the angular fluxes in a cell are then generated by computing the linear DFEM SN equations for a simplex on each subelement and assembling the equations over the subelements. The result is a (piecewise) linear continuous finite element method spatial discretization on the cell that is coupled discontinuously to its neighbors through the standard DFEM upwinding technique. The method is presented in two-dimensional Cartesian coordinates. Numerical experiments indicate the method has numerical properties that are suitable for a new SN spatial discretization.
