De Ruyter strikes back – blows the lid on ANC corruption

Site were identified decades ago. I can't remember if the land was actually decided on and bought, but in the vicinity of Jeffrey's Bay somewhere was one possibility.

As they use sea water for cooling I think it will have to be in an area with cooler water, so probably on the Cape Coast somewhere.

Sea water temperature is only relevant to cooling equipment sizing, it would not affect the location, as many if not more rely on River or Lake water for cooling than seawater.

And in an earthquake stable place as well , Koeberg is apparently very stable in that respect .

Yes 100% correct.

True, but we are fortunate to have the cold sea current on our doorstep. Of course, it isn't the only important factor.

If you Google "infrastructure overruns" you would be surprised at some massive budget and time overruns on projects in the 1st world. And I mean massive.

Olkiluoto 3 was the first of the new generation of EPR reactors, the Contractor Areva/ Framatome/ Siemens wrote off the losses against tax to R&D as it was first of a kind.

The Eastern Cape site was at Thyspunt.

Thanks. I couldn't remember and was thinking just about every Afrikaans male name - punt. All except Thys!

Saldanah would be a good site, maybe saldannah steel would be able to compete international if it had its own nuclear powerstation

Heck, how would the pay for it?

Thats what you and I are here for......

I will leave that account in your capable hands, thanks.

Remember, Nuclear power is not cheap, it is a massive CAPEX but then FIXED cost for its lifetime, that is its advantage, no price fluctuation for its lifetime which has been a huge advantage for the French, no energy price fluctuation as fossil fuel pricing moves.

I remember watching a video about the costs of nuclear vs coal, gas and renewable. Nuclear is the most expensive until about 25 years but after that it rapidly becomes by far the most economical as the fuel cost per mw/h is so low

Renewable was cheapest and fastest to set up but over 50 years its by far the most expensive as over that time frame it will need to be installed twice and the supply is very unreliable

Same as what I said, Nuclear is a high CAPEX, but then stable costs and supply.

EPR reactors ??? What are they , in comparison to Koeberg .
What about the SMR,'s ?

Sorry Dux, I should have elaborated.

The EPR is the European Pressurised Reactor, or when you want to sell to China or USA, The Evolutionary Pressurised Reactor.

The EPR is essentially just the latest version of Koeberg, it has a lot of new features, some of the main ones are the "passive" safety features, the roof has a massive "fire pool" built in, so the reactor overheating system is not pump driven needing power for the pumps and has fusible plugs not electrically driven valves, so no power related safety systems. There are loads of other upgrades in the detail.

One of the big issues for the constructors, is that the acceptance standards were set years ago, but technology races forwards so the Examination Techniques mean you can find defects which you would historically not found, the safety factors are there to protect for such defects, but the balance between the NDE techniques and the Acceptance Standards are getting blurred as the Codes do not always keep up.
We had a technique called "phased array" used on equipment, where we had a supposed "weld defect" it was picking up the difference in grain structure between the root of the weld done with TIG and the balance of the weld done with Submerged Arc Welding, these can be very expensive discussions if it goes against you.

SMR's are not a reality yet and I am not convinced they will be in our lifetime.

Thank you , yes I would imagine safety being of paramount importance , after all this is not some toy to be played with .

I thought you just wanted to post in stereo.

 

[Cracker]

I was reading about these reactors and their history on Wiki ....................... seems inconceivable that politicians get to decide on these things.

I mean, politician 1, in his wisdom decides nuclear is the future, and of we go, spending billions. Next year, he throws the bones again, and renewables are all the rage.

 

[BuRP]

EPR is

I stopped reading at 'pressurized' ..... which is old fashioned, costly, dangerous and superfluous.
MSR please....
