The brief, recently produced video below does a reasonably good job of explaining a complex subject in a way that is understandable and digestible.
Unfortunately, there are a couple of minor points that are not accurate. They detract from the video’s value, but should not spoil the overall point. Perhaps the originator will take the time to complete some fact checking and make a corrected version.
(For example, Brian states that the Chernobyl reactor was a “prototype, generation one reactor.” He later claims that “it was the oldest reactor operating, decades obsolete.” Neither of those statements are true. The reactor that blew up was not the oldest reactor, in fact, it was unit number 4 on a station where construction started in the 1970s. The specific unit that blew up was only completed 3 years before the accident, so advanced machinery age was not a factor in the event. The reactor’s RBMK design was not even all that obsolete; it was completed during the second generation of nuclear power plant design using different selection criteria than would have been used in countries outside the Iron Curtain.)
