The reactor was shut down a lot due to grid failures (also the bolt in rotor incident and now the problem with the turbine). Eskom have to comply with the regulations set by NERSA and it is illegal to operate a nuclear reactor without sufficient backup power from the grid. So as soon as sync is lost with the grid at the switchgear the reactor has to shut down. It can then be brought online again with the on site Diesel generators. Nothing ever went wrong with either of the nuclear reactors at Koeberg!Ah, my bad.
But still I am not happy with the idea of living upwind of a reactor that had to shut down what was it? Three or four times last year?
PS What do we do with the plutonium produced at Koeberg if I am not mistaken about that as well?
The big problem is that there is only one base-load power station in the Western Cape. The six-packs in Mpumalanga are almost constantly running with only four or five units operating, due to incidents (turbine blade cracks, boiler cracks, turbine blades being shed, coal shortages, etc) and \ or maintenance. The fact Koeberg is nuclear also doesn't help much when the media gets hold of a story.
Koeberg isn't a breeder reactor, so it doesn't produce much Plutonium. Nuclear waste (which includes the entire gamut of nuclear decay products) is stored at Vaalputs in the Northern Cape.
