World's second EPR nuclear reactor starts work in China

The two EPR reactors at the Taishan nuclear power plant will be the most powerful in the world when fully completed and can supply five million Chinese users, its owners say

A next-generation EPR nuclear reactor in China has carried out its first chain reaction, French energy giant EDF announced Wednesday, becoming the second using the much-delayed European technology to reach the milestone.

The fission reaction at the Taishan 2 reactor on Tuesday follows the Taishan 1 becoming last year the first of its kind to advance to the operational stage.

"The was authorised and yesterday the Chinese reactor carried out a for the first time," EDF chairman and CEO Jean-Bernard Levy told Europe 1 radio on Wednesday.

EDF, which helped design the European Pressurised Reactor (EPR), is a minority shareholder in the Taishan project, which is a joint venture with China's state-run CGN and regional Chinese utility Yuedian.

The first was loaded into the Taishan 2 reactor in early May in the southern Chinese province of Guangdong.

Levy said that Taishan 1, which in December became the first EPR to enter into commercial service, was "working very well".

The two EPR reactors at the Taishan will be the most powerful in the world when fully completed and will be able to supply five million Chinese users, the companies have said.

EPR reactors—which use a pressurised water design—promise advances in safety and efficiency over conventional reactors while producing less waste.

But EDF has faced serious problems rolling out the technology and has managed to sell just a handful of the reactors as construction problems piled up.

EDF has been building an EPR reactor at Flamanville along the Atlantic coast of northwest France. It was originally set to go online in 2012 but the project has been plagued by and budget overruns.

Levy acknowledged that the "difficulty" of the Flamanville project had been "underestimated."

French President Emmanuel Macron has asked EDF to study the feasibility of building more next-generation EPR nuclear reactors in the country, but will wait until 2021 before deciding whether to proceed with construction.

Most probably due to rampant corruption, as is the case in most such delays.

A pair of entangled EPR reactors, which might be thousands of miles apart, seem to communicate instantaneously. A spin measurement made on one reactor is guaranteed to have the opposite value when measured on the other reactor. The idea for the EPR reactor comes from a paper written by Albert Einstein and collaborators. Einstein famously quipped, "God does not play dice with nuclear energy."

'Seem', but as precisely Einstein showed no signal can go between - both quantum mechanics and relaivity is preserved in quantum particle physics. Entangled spin correlations are seen and broken in many places over indefinite instances, and no one are much bothered these days.

Why mention the reactors, and an incorrect context? If it is a joke, no one are much laughing these days either.

Yes, that was just meant as a dumb joke. But why are no one much laughing these days either? Laughter can be good for the soul.

Well, it was a bit esoteric but I found it funny.
