How to make Plutonium

TL;DR

Scientists synthesize plutonium-238 to power spacecraft that travel to distant places too far from the Sun to use solar cells.

Questions & Answers

Q: Why is plutonium-238 used to power spacecraft in distant locations?

Plutonium-238 generates heat through radioactive decay, providing power where solar cells are not feasible due to the distance from the Sun.

Q: How is neptunium converted to a solid oxide powder?

Neptunium, supplied as a solution, undergoes a process involving a rotary kiln to convert it to a low concentration oxide powder.

Q: What is the purpose of pressing neptunium oxide mixed with aluminum powder into pellets?

The pressed pellets serve as fuel for spacecraft, ensuring controlled and efficient power generation during the mission.

Q: How is the quality of the pellets ensured?

The pellets are measured for diameter and length using lasers, and a visual inspection is performed to verify the presence of neutron oxide (dark green color) and plutonium oxide (purplish/magenta color).

Summary & Key Takeaways

• Plutonium-238 is synthesized from neptunium and used to generate heat through radioactive decay, powering spacecraft for missions in remote locations.

• Neptunium, supplied as a liquid solution, is converted to a solid oxide powder through a process involving a rotary kiln.

• The neptunium oxide is mixed with aluminum powder, pressed into pellets, and measured for quality before being used as fuel in spacecraft.
