WebPM-3A operated at a uranium-235 enrichment of 93 percent. The PM-3A (Portable, Medium-power, 3rd generation) was a plant installed to provide power for the McMurdo Base in Antarctica. During 1970–1971, it achieved a world-record power run. It was one of the first shore-based power plants to use solid-state equipment. WebDec 14, 2024 · HEU, uranium that has been enriched to increase the proportion of the U-235 isotope to over 20%, is required for the construction of a gun-type nuclear device, the simplest type of nuclear weapon. The higher the enrichment level, the less material is needed for a nuclear explosive device.
