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.

Mass attenuation coefficient, effective atomic number, and electron density of 12 organic acids, acetic acid (C2H4O2), acrylic acid (C3H4O2), benzoic acid (C7H6O2), butyric acid (C4H8O2), citric acid (C6H8O7), formic acid (CH2O2), lactic acid (C3H6O3), malic acid (C4H6O5), oxalic acid (C2H2O4), salicylic acid (C7H6O3), tartaric acid (C4H6O6), and valeric acid (C5H10O2), were computed in the wide energy range of incident photon energies from 1 keV to 100 GeV. The variation of these parameters has been studied as a function of incident photon energy. Further, a comparative study of two different methods used to compute effective atomic number is completed.
