Title: Finland's EPR delayed again
Post by: dan_b on October 12, 2017, 09:45:08 AM
More delays at Olkiluoto 3, they're now not expecting it to go nuclear until 2019 - a whole 10 years later than planned.

Like the start of the second paragraph in that report "This means that the troubled nuclear enemy project..." - do you think the journalist is biased :hysteria

Probably realistic. The whole EPR saga to date has been an eff-up of ginormous dimensions. I hope we get some good news soon from the Chinese ones. Or Flamanville. (Me, clutch at straws? oh no no no...)

For nuclear supporters there is some good news for Flamanville, in that it will probably start generating before 2022, in order to prevent a UK escape clause om HPC. The bad news though being, that this will require them to use the faulty reactor lid to meet the deadline.  ???

Latest news appears to be Flamanville is going hot the end of next year, and supplying to the grid Q1/2 2019. "Faulty" reator lid is probably overstating it. AIUI it means the service life will probably be reduced from the nominal 60 years to something shorter. I'll be dead by then.

No, EDF is planning to replace it by 2024. Sadly, "faulty" isn't over-stating it: it's been analysed and determined to be unfit for purpose.

But safe to operate.

In fact if you read it, what is says is that a couple of the areas in question cant be inspected, so the safe thing to do is to replace it. Which is a touch different to "unfit for purpose"

When it comes to nuclear should we really settle for  ... "Ahhh she'll be fine"?

I often read comments from nuclear advocates saying that nuclear is only economically non-viable because of all the over-safety regulations. After all, what's the worst that can happen, Fukushima went bang with a little "b" so that's not so bad. So even when the  sh*tfan: it still didn't go big "B" bang, so what's the problem, besides the $200bn clean up bill!

French Nuclear is up the creek without a paddle at the moment.

What it says is that it is known that the material is flawed, and prone to failure. That makes it unfit for purpose, by any sane measure. YMMV.

Finlands EPR reactor pressure vessel forgings were sourced in the Main from Japan Steel Works in Kobe Japan. These are not a problem.

I dont know if the issue of the reactor control system and protection systems been sorted. Apparantly these were all under the control system computer, hence no diversity, redundancy, or segregation.  I heard the Finnish Nuclear regulator had reservations about this years ago, and until Areva dealt with it, the regulator would not grant an operating licence. Typical case of French shoulder shrugging. Finnish regulator is not going to be fobbed off.

Them Russians seem to be able to get their VVER PWRS working well. Selling them to Saudi Arabia last week or so.

Kobe Steel no problem?
