"The latest ultrasonic inspections have detected a substantial number of
new micro cracks in nuclear reactors at the Tihange and Doel power
plants in Belgium since the last study conducted three years ago,
Belgian and German media report"

"At least 70 additional cracks were uncovered at the Tihange 2 nuclear
reactor during an ultrasonic inspection in April of this year, Belga
news agency reports. Some 300 new flaws have also allegedly been
discovered at the Doel 3 reactor tank during a check last November,
according to tagesschau.de"

So? reactor cracks on old plant is why they have the routine statory
outages for inspection.

Yes. I wasn't implying otherwise, just quoting the article, but you
know how the press loves to sensationalise anything to do with matters
nuclear.

Also worth mentioning that the two reactors in question are nearly 35
years old. In that time they will have experienced materials
embrittlement due to radiation, something I understand is not yet fully
understood but is being researched.

The articles also don't make it clear where the cracks are. I read it
as being in the boiler at one (if the boiler pressure vessel let go,
presumably there'd be a lot of steam but no radiation if the primary
coolant didn't escape), and in the other it's the reactor pressure
vessel (quote: "reactor tank") itself.

Of course, in that intervening 35 years, materials science has come on
in leaps and bounds and (hopefully) pressure vessels will be constructed
to a far better standard. I note that Flamanville's pressure vessel has
been passed fit for use despite concerns about excessive concentrations
of carbon creating potential weak spots in the steel.

So nothing. I'm merely quoting an article for intelligent comment from
those interested, which kinda excludes you.

Have you emigrated yet? Perhaps you could give the Belgians the benefit
of your extensive experience in the nuclear industry from the comfort of
your armchair? snerk

Oh dear. So you are claiming you had no ulterior motive whatsoever in
posting that?

Yet when challenged you go into denial and change to a personal attack?

I will leave the readers to work out where that one is at...

At least once, yes.

No. I'll leave that to you.

No, they have to be exaggerated until you get the desired public response.

Worth saying that UK scientists made significant contributions to the
theory of Fracture Mechanics, and its implementation and application to
nuclear plant. Also to radiation embrittlement which has been a live
topic for decades.

Thanks.

The effect of Brexit on membership of Euratom is also a worry:

Well it has to make sense that any material built from atoms has to suffer
degradation when high energy particles are involved for a long time period.
I think the point is that some impurities in steel for example are more
adversely affected making stressed or weak points over time.
I'm sure way back when I was young there were designs using double layer
pressure vessels to allow the particles to dissipate their energies before
they reached the structural part.
