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.

The possibility of constructing an intense hard-spectrum neutrino source based on the β‾ decay of 8Li (T1/2 = 0.8 s) is studied. Applications of such a source are considered in neutrino investigations. The source can be developed on the basis of a neutron-to-antineutrino lithium converter through (n, γ) activation of 7Li isotopes irradiated by neutrons from the active zone of a reactor. The physical parameters of the lithium converter are compared with those of other neutrino sources. Different geometries for a converter using heavy water are considered. The converter efficiency is calculated as a function of the purity of the 7Li isotope and the expected tritium activity values. The cross section of the neutrino-deuteron reaction increases rapidly in both the neutral ( + d → n + p + ) and the charged ( + d→ n + n + e+) channels as the converter efficiency is improved. The real efficiency is 9%, and the cross sections are enhanced by factors of 2.5 and 5 in the respective channels.
