It's a Molten Salt Reactor in the 1980s. They are good. (And very safe. No Chernobyl for you.)
Now that's understating it a little, Chernobyl was a product of the single least safe reactor design
ever put into serialized construction.
Carbon moderated reactors are built, particularly with gas cooled reactors, and if you make the right choices they can be fairly safe (graphite is still the most dangerous moderator - used mostly as a cheaper alternative to heavy water, since much like heavy water it doesn't absorb as many neutrons as light water), but the RBMK design makes none of those 'right choices'. It was designed about being the absolute cheapest and most easily scaled reactor imaginable (the exception being that they didn't fully utilize the advantage of graphite or heavy water moderators, which is that you can design the reactor to run on completely unenriched uranium), at the cost of everything else (also it wouldn't have been the cheapest if they'd gone ahead with building it a containment building, because RBMKs are huge not only in power output but also in physical dimensions, so a sturdy containment building costs about as much as the entire rest of the powerplant, reactor included).
This is no Chernobyl, no Fukushima,
and no Three Mile Island
(Still don't build the things directly on the coast within fifteen meters of sea level, though - do not taunt Neptune, but rather show adequate respect to his boundaries by building maybe thirty meters above sea level. You never know what the highest recorded tsunami in history will be in forty years time.)
