Researchers from the Department of Energy’s Oak Ridge National Laboratory have created plutonuium-238. This is the first time since 80’s researchers have produced plutonium. The government just gave NASA a huge budget, fortunately. NASA began funding the DOE Office of Nuclear Energy with almost $15 million annual budget to regain the department’s plutonium-238 production. In order to produce plutonium-238, scientists mixed neptunium oxide with aluminum. After mixing neptunium oxide with aluminum, they pressured the mixture into high-density pellets. Then they used High Flux Isotope Reactor to irradiate the pellets, which produce neptunium-238.

Bob Wham, the head of the project for the lab’s Nuclear Security and Isotope Technology Division said “Once we automate and scale up the process, the nation will have a long-range capability to produce radioisotope power systems such as those used by NASA for deep space exploration”.
He continued “With this initial production of plutonium-238 oxide, we have demonstrated that our process works and we are ready to move on to the next phase of the mission”.
