There is a lot in this interview to absorb and chew over, not least Kemm’s view that it makes sense to dust off SA’s scrapped PBMR programme.

Researchers develop advanced model to improve safety of next-generation reactors

The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown, the likes of which haven t been seen since the Chernobyl disaster in 1986.
