Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Accurate nuclear data are needed for the development of clean nuclear power systems that employ accelerator-driven technologies. To meet this need for thorium - based on the experimental data of total, nonelastic-scattering, fission, and other reaction cross sections and elastic-scattering angular distributions of 232Th - all cross sections of the neutron-induced reaction, angular distributions, energy spectra, gamma-ray production cross sections, gamma-ray production energy spectra, and number of neutrons per fission are calculated and analyzed for n + 232Th at incident neutron energies from 0.05 to 20 MeV. The analysis includes the double-differential cross section for neutron, proton, deuteron, triton, and alpha emission. Theoretical calculations are compared with existing experimental data and other evaluated data from ENDF/B6 and JENDL-3.
