Glad they got a high temperature gas cooled reactor up and running! I do dislike the terminology/categorization around 'fourth generation'. The first ever proposed commercial reactor (the Daniels Pile) was a pebble bed gas cooled reactor concept, worked on at Oak Ridge in the 1940s. We've built lots of gas-cooled reactors in the past, including helium cooled ones. Such as: * Peach Bottom * Fort St. Vrain * HTTR * Dragon * HTR-10 * AVR pebble bed * THTR-300 * Ultra-High Temperature Reactor Experiment (UHTREX) Nitrogen-cooled ones, such as ML-1 and GCRE CO2-cooled ones, like EL4, Lucens, AGR, Magnox Air-cooled ones like HTRE Liquid-hydrogen cooled ones like NERVA It's kinda dumb to call this the first 4-th gen reactor.
