Twin HTR-PM reactors will drive a single 210 MWe turbine in China’s high-temperature pebble bed reactor. This new reactor could eventually be mostly factory mass-produced. The higher temperature will make it about 45% thermal efficiency versus 34-40% efficiency for pressure water reactors. 18 more HTR-PM units are proposed at Shidaowan. * pebble bed reactors have 9 grams of uranium in each tennis ball-sized pebble * the pebbles can melt a plug and spread out in a pan so that gravity and physics prevent a meltdown. This makes them walk-away safe. The higher temperature means that the waste heat can be
