@morris_vincent @Sogn0difarfalla @AvvocatoAtomico @Luizaconlaz La strategia politica deve solo dare i requisiti: serve energia abbondante, low carbon, affidabile ed economica.

Da lì decidere il mix energetico per soddisfare questi requisiti è solo tecnico.
E lì sì che conta essere esperti, altro che.

@morris_vincent @AvvocatoAtomico @Luizaconlaz Ti faresti operare a cuore aperto da Parisi? Dopotutto ha un Nobel per studi rivoluzionari su sistemi fisici complessi, sarà sicuramente un luminare anche nella cardiologia e chirurgia.

@ignaziano @AvvocatoAtomico Che argomento arguto e convincente.

@Jordan_W_Taylor In our shop we make circular welds of 5m diameter of 100mm+ material thickness for steam generators in about two weeks on average. That’s not really the driving factor for the time it takes to perform a circular weld. NDE inspections + PWHT take up way more time.

[Leonardo Mariano @Split_Actinides]

@Jordan_W_Taylor That’s both to minimize the welds done in the shop and also the in service inspections to be performed in a radiologically hot environment. You also reduce weld repairs, deformations and dimensional tolerances are easier to get.
Naturally, big forgings are costly, but worth it.

Today, we released a comprehensive, independent report detailing the significant economic impact of deploying a fleet of 10 AP1000® advanced modular reactors in the United States.

The study found that the construction phase of a 10-unit AP1000 fleet can generate more than $93 billion in GDP for the U.S. and support 44,300 high-paying jobs annually for 13 years. Over its 80-year lifetime, the fleet would create an additional $1 trillion of GDP while supporting 22,500 jobs annually.

Let's get to work!

Europe needs homegrown, low-carbon energy sources.

Nuclear & renewables together have a key role to play

Nuclear energy is available around the clock, providing electricity all year.

Europe has been a pioneer in nuclear technology.
And can lead again ↓ https://t.co/Eg7gl1548K

Goodbye aircraft impact assessment! 👋

[John Fingleton @JohnFingleton1]

Britain needs nuclear power. Our nuclear projects are the most expensive in the world and among the slowest. Regulators and industry are paralysed by risk aversion. This can change. For Britain to prosper, it must.

Earlier this year, the Prime Minister appointed me to lead a Taskforce to set out a path to getting affordable, fast nuclear power Britain.

Our final report today sets out 47 recommendations, among them:

- Creating a one-stop shop for nuclear approvals, to end the regulatory merry-go-round that delays projects at the moment.
- Simplifying environmental rules to avoid extreme outcomes like Hinkley Point C spending £700m on systems to protect one salmon every ten years, while enhancing nuclear's impact on nature.
- Limiting the ability of spurious legal challenges to delay nuclear projects, which adds huge cost and delay throughout the supply chain.
- Approving fleets of reactors, so that Britain’s nuclear industry can benefit from certainty and economies of scale.
- Directing regulators to factor in cost to their behaviour, and changing their culture to allow building cheaply, quickly and safely.
- Changing the culture of the nuclear industry to end gold-plating and focus on efficient, safe delivery.

If the government adopts our report in full, it will send a signal to investors that it is serious about pro-growth reform and taking on vested interests for the public good.

A thriving British nuclear industry producing abundant, affordable energy would be good for jobs, good for manufacturing, good for the climate, and good for the cost of living. And it could enable Britain to become an AI and technology superpower.

Britain can be a world leader in this new Industrial Revolution, but only if it has the energy to power it.

Our report is bold, but balanced. Our recommendations, taken together and properly implemented, will forge a clear path for stronger economic growth through improved productivity and innovation. This is a prize worth fighting for.

[Leonardo Mariano @Split_Actinides]

@Dr_Keefer That would be safe to assume.
I’m eager to see how it will play out in the end.

[Leonardo Mariano @Split_Actinides]

@Dr_Keefer Heavy component fabrication has even more options, Westinghouse has an internal capacity (also in Italy) for it and can definitely rely on the spanish Ensa.

[Leonardo Mariano @Split_Actinides]

@Dr_Keefer To name a couple for the forging capability, Doosan is probably the main supplier, much more so than JSW, and an italian supplier (Forgiatura Vienna) is being qualified and is currently under preparation to deliver the main forgings for the polish AP1000s.

[Westinghouse Nuclear @WECNuclear]

We're thrilled to announce a strategic partnership to accelerate the deployment of nuclear power in the U.S.

At the center of this new partnership is at least $80 billion in new reactors to be constructed across the U.S. using Westinghouse AP1000® and AP300™ nuclear reactor technologies.

☢️ The strategic partnership also involves Brookfield and Cameco, and will hit two of Trump’s goals: being a leader in nuclear power development and in AI

Legal challenges have added over 1,750 days of delay to Hinkley Point C and Sizewell C.

None of them have been successful
