So what happens to the 20GW used at night? And where do you see the increase by 10 to 15 during the day?? Do you not know how to read a graph?
I know that long Loadshedding will be back though
You know wind picks up when the sun goes down, right?
Does it really?? Wow you keep saying this like it's fact, where do you even get this 'truth' from? Wind doesn't magically pick up at night, in fact it's pretty consistent, examples UK yesterday grid watch shows that it actually starts to drop around 4pm.
They don't specifically list the areas of concern for break-down. They always talk of aging infrastructure but concrete structures can, will and do last hundreds of years. One day when humans are gone the concrete structures will be our legacy.
NEW FRAME ANALYSIS : Retrofitting Koeberg power station is more likely to provoke a catastrophe than preserve energy — the plant should be closed
Concerns have been expressed about staff turnover at the ageing facility. Instead of extending its lifespan, renewable energy should replace it.www.dailymaverick.co.za
Well, we're definitely not putting in the safety features that the french have mandated in their retrofits for the exact same design, so there is a case to be made for both.
I wouldn't rely too much on "concrete structures can, will and do last hundreds of years" as it is only if they are designed with that lifespan in mind (also note that conventional concrete has not really been around in this application for very long, less than one hundred years). What was the design life of the critical Koeberg concrete structures?

Any details, I'm curious
Since my partner is in the construction industry and I'm privy to how this whole process works. A concrete structure has a "lifetime" which is an estimate. After that time they re-evaluate and make repairs assuming any are required. It happens pretty often that buildings after 100 years are extended for another 50 years. Buildings like the Koeberg building would have had incredible thick concrete pads, so it is unlikely the structure has any problems. They do seem to be concerned about corrosion, likely from the ocean, so they are adding galvanic protection.

Their demands contradict each other. They want a core catcher but not extend the life of the plant. Or does that implicitly mean some of the demands are optional. LOLSee #23
The French are mandating core catchers in their PWR retrofits for safety - those are the same design as Koeberg.
Are we mandating core catchers?
How many guesses should I need to give you.
NOT IN MY BACKYARD: Koeberg nuclear power plant rejuvenation: Protesters say silence is a killer
With Eskom on the verge of beginning its R20-billion project to extend the operating life of the Koeberg nuclear power station by 20 years, civil society organisations held a protest to question its safety and call for public participation in decision-making processes. Eskom, in turn, has argued...
The petition calls on André de Ruyter, chief executive officer of Eskom, to:
- Acknowledge that the Koeberg nuclear power station will never be as safe as modern nuclear power station designs;
- Shut down the station in 2024, as originally planned;
- Not run the station after 2024 while it lacks modern safety features, such as a core catcher;
- Avoid the unnecessary load shedding that will result from efforts to extend the station’s life;
- Not spend billions of rand upgrading a station from the 1970s;
- Divert the funds allocated for extending the station’s lifespan to support community-owned renewable energy, and work on a permanent solution for the disposal of over 1,000 tonnes of high-level nuclear waste currently at the Koeberg site.
To reierate the French nuclear oversight will not pass any retrofit PWR (like Koeberg) unless they have core catchers.
Definitely don't agree with this statement. The French designed PWR reactors have stood the test of time. The newer generation reactors haven't been operating that long. A lot of modern reactors are about squeezing out more efficiency. I'd love a list of these safety features this specific plant is missing. Even Chernobyl wouldn't have benefitted from a core catcher, other than preventing people digging tunnels, placing a heat sink and stuff (which has now been proven had no effect and the fuel hadn't molten into the ground).
Thats not my statement, its from the Daily Maverick article.
Not a that many, the Western side perhaps but the Eastern side has had a cool wet summer. Even Durban hasn't really had a hot day from what I can see.
Yours is nonsensical however....
He's gone very quiet over this wind picks up malarkey when I've shown him that it in fact doesn't. It's almost as if wind can do what it wants any hour of the day and you can't guarantee it.
No man, we just need to stop using electricity at night, the 20GW that is used, it can be done with magic and mysticism or with great expense using batteries.
