Refuelling of a unit (900 MW) at Koeberg is significant to the Western Cape as it will affect the stability of supply in that part of the country if something else also goes south.
AFAIK they never refuel both units at the same time. Eskom are currently experiencing problems with about 4000MW of their conventional (read coal) plant. That is more than 4 Koeberg equivalent units or about 7 large coal units (600-700MW/unit). So if everything else was OK, one unit at Koeberg is not a serious issue (The Koeberg process has been in place for decades and never before such a serious issue). But everything is not!

One of the units is being refuelled right now; I guess it's the other one that will be refuelled in 2009?

AFAIK, they are doing manitenance on one reactor and a refuel on the other. ie. Koeberg is down.

Interesting:
The pebble bed reactor (PBR) is a design, revived by the South African utility, ESKOM, near the turn of the century. In the United States, the design and progress toward licensing appears to have slowed. Interest by Exelon, an early proponent, has waned.
Did we actually revive something good? :)

Depleted uranium is very dense and is used for piercing armored vehicles, and is weakly radioactive.

I don't think so. one down being refueled and maintained, other is up and running.
But, what is interesting is that during the bolt episode the refueling was held back for 3 months while a new rotor was obtained.
What is of interest to me is why the hell has Eskom gone ahead with the scheduled maintenance when there's a power crisis instead of delaying it until the wet coal has dried?

I assume they have been putting it off for some time - it is now depleted and needs fuel - it is "dry".

Think our depleted fuels go to a place called Swartklip, somewhere in the Northern Cape, literally between nowhere and nothing, gets buried. ***us did an insert on it not so long ago. Not so sure if my depleted memory recalls the right name now that I typed it!

That was not depleted uranium though, it was pure was it not? As in it leaked out of an operational facility. Different to what Koeberg buries in the ground and what the army puts on their bullets.

Media release 7 August 2007
KOEBERG REFUELING OUTAGE
Tuesday 7 August 2007: Koeberg’s Unit 1 will shut down on Monday 13 August for refueling and maintenance. The outage will last until the final week in October due to the large scope of work that has to be undertaken. During this period, Unit 2 will continue operating.
The Koeberg units have to shut down every 16 to 18 months to undergo refueling and maintenance. Unit 1 has operated since May of 2006 after coming back from having a generator fixed. During the refueling a third of the fuel will be replaced as it is nearing the end of its useable life.
This is a planned outage and has been taken into account within the Generation production plan. The forecast for electricity supply during this time period is traditionally lower and provision has been made to ensure that there will be enough power to supply the Western Cape as well as the rest of the country. The new Open-Cycle Gas Turbines, Ankerlig at Atlantis and Gourikwa at Mossel Bay are fully operational and will help supply power during the peak periods (06:00 till 08:00 in the morning and 17:00 till 20:00 in the evening). Power from Koeberg’s Unit 2, the Open-Cycle Gas Turbines as well as the power that can be transferred in via overhead lines from Mpumalanga will ensure the continuity of supply to the Western Cape.

New storage place for depleted uranium could be Milliwatt Park, Union Buildings. With luck the resultant radioactivity could lead to some beneficial mutation, like maybe growing some brain cells.
