I couldn't understand from the article what runs a turbine (hot gas?). Can someone explain how electricity is generated?
- asdfadsfgfdda 4y ago>The mobile microreactor would be coupled with a power conversion system that generates approximately 1 to 5 MWe using an open Brayton gas cycle https://www.cto.mil/wp-content/uploads/2022/05/Final-EIS-Vol-1-Distro-A.pdf https://www.cto.mil/wp-content/uploads/2022/05/Final-EIS-Vol... Sounds like an air compressor+turbine, but heated by a heat exchanger instead of burning fuel.
- NickRandom 4y agoNote IANANE (I am not a nuclear engineer) but most probably by using a closed Brayton cycle. The gas is heated which expands and drives the turbine, the hot gas is cooled via a heat exchanger, compressed then fed through the reactor again. https://energy.mit.edu/wp-content/uploads/2017/02/2-3.-HTGR-Brayton-Cycle-YAN-MIT-talk-r1-min.pdf https://energy.mit.edu/wp-content/uploads/2017/02/2-3.-HTGR-... has a diagram on page 2 that explains it better than I can
