User:Barr0069/Plutonium-238
In a study reported by SAE International in 1966 described the potential for the use of plutonium-238 in radioisotope power subsystems for applications in space. This study focused on employing power conversions through the Rankine cycle, Brayton cycle, Thermoelectric conversion, and Thermionic conversion with plutonium-238 as the primary heating element. The heat supplied to the Brayton cycle was consistent between the 400° C and 1000° C regime resulting in an efficiency greater than 20% but future technology could reach an upper limit of 2000° C. Thermionic conversion could provide similar efficiencies if proper conditions reached.[1]

If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |
