#EPR nuclear reactors

[lejournaldupeintre]

Flamanville stopped one day after entering production.

The Flamanville EPR reactor had on Monday received authorization from the French Nuclear Safety Authority (ASN) to proceed with divergence operations – the first nuclear fission which allows electricity production to finally begin. EDF teams carried out these first divergence operations of the reactor on Sept. 3 but on the morning of Sept. 4 the reactor automatically stopped, said…

Secondo il Signor Bonelli, il nucleare è una forma insicura e inquinante per produrre energia elettrica, costosa e ormai superata dalle energie rinnovabili.

Diamo una lezione di... Inglese al Signor Bonelli... EDF ha rilevato la flotta nucleare britannica nel 2009 con lo scopo di migliorare le prestazioni, l'affidabilità e la durata dei reattori ancora operativi.

A partire da quella data erano 8 le centrali nucleari ancora con combustibile nei reattori.

Di questi 8 siti, oggi, 5 sono regolarmente in funzione (Sizewell B, Torness, Heysham 2, Heysham 1 e Hartlepool) e 3 in fase di disattivazione (Hunterston B, Hinkley Point B e Dungeness B). Ha rilevato i siti quando ha acquisito British Energy nel 2009.

Vorrei tralasciarlo, ma il dovere di informazione mi impone di riferire che l'azienda sta anche costruendo la nuova centrale nucleare di Hinkley Point C nel Somerset e ci sono piani avanzati per una replica di Hinkley Point C a Sizewell C nel Suffolk; entrambe sono e/o saranno dotate di 2 reattori EPR da 1600 MWe.

EDF ha migliorato le prestazioni delle unità e migliorato la longevità, la maggior parte delle quali del tipo AGR (Advanced Gas Cooled Reactor) con core del reattore realizzato in mattoni di grafite.

Tra i reattori citati, Sizswell B è un'unità di tipo PWR (Pressurized Water Reactor), programmata per un'estensione della vita operativa fino al limite degli 60 anni, fino al 2055. Heysham 1 e Hartlepool opereranno fino al 2027, Heysham 2 e Torness fino al 2030, guadagnando per ogni unità almeno 5 anni rispetto al limite iniziale prefissato. Il limite è dettato dallo stato di usura dei mattoni in grafite e dai danni eventualmente riscontrati/riscontrabili nei canali preposti ad accogliere, sia il combustibile nucleare, sia il passaggio delle barre di moderazione.

Nel 2024 i 5 reattori operativi hanno generato 37,3 TWh, quasi 4 volte di più di quanto prefissato e stimato dalle autorità britanniche, a dimostrazione delle perfette opere di manutenzione e prestazioni mantenute nel tempo. Da dire, UK ha importato energia nucleare dalla Francia per un totale di 21 TWh.

Dall'entrata in servizio delle centrali nucleari in UK, il 1976m le stesse hanno contribuito a generare reddito per 123 miliardi di sterline e centinaia di migliaia di posti di lavoro. Ancora, fino al 2016 sono stati operativi oltre 31 mila addetti per la manutenzione e le operazioni e per ogni posto di lavoro nel settore nucleare ha contribuito a generare 5,1 posti di lavoro in cascata in tutti gli altri settori dell'economia britannica, permettendo le operazioni ad oltre 1500 aziende collegate alla costruzione e alla manutenzione solo in UK.

-------------------------------

quello con le sue idiozie e di quelli come lui ci hanno messo in una situazione fallimentare...dovrebbero pagare loro, per i danni fatti, e invece pagano sempre altri, mentre lui può fare una vita da sultano grazie allo stipendio da parlamentare.

------------------------------

Bonelli è una delle tante rotelline di sinistra che ha contribuito, e vuole continuare a farlo (vedesi TAV e Ponte), per distruggere l'Italia. Ti cito un numero diverso dai 123 miliardi di sterline delle quali ha beneficiato l'economia UK dal 1976 ad oggi. Parlano tanto di ambiente e di CO2? Bene, il nucleare britannico ha contribuito ad evitare 1,1 miliardi di tonnellate di emissioni di CO2, Bonelli non lo dirà mai.

Construction progress, January to December 1976, on the Olkiluoto nuclear power station in Finland. These two units, boiling–water reactors supplied by the Swedish firm ASEA–ATOM, were originally rated at 660 MW each, nowadays at 890, almost equivalent to adding a third unit. And the French–built 1575 MW EPR (PWR) is finally in operation there too.

EPR nuclear reactors are just not performing well at all.

 The French EPR reactor was supposed to be built in 4 or 4,5 years, and toproduce 13 TWh of electricity per year. (As for EDF:s promise, see forexample https://lnkd.in/dFXe5geb point 19.) At 13 TWh/year and operating when planned to do so, the first 4 reactors, in Finland, France and China should have produced about 648 TWh by the end of 2024. According to newdata from the IAEA PRIS they have…

El reciente Programa Indicativo Nuclear (PINC) de la Comisión Europea, con su estimación de 241.000 millones de euros de inversión necesaria hasta 2050, se presenta como un pilar esencial para la descarbonización y la competitividad europea. Sin embargo, tras el lenguaje técnico y las cifras impresionantes, se esconde una estrategia energética plagada de contradicciones, riesgos económicos y una peligrosa distracción de soluciones más eficaces y rápidas. Imagen: El elevado precio del gas ha reabierto un debate antiguo y superado pero recurrente: el de la energía nuclear./ Fernando Valladares La narrativa oficial: Nuclear como complemento necesario La Comisión argumenta que: La nuclear es “descarbonizada”: Por tanto, indispensable para alcanzar el 90% de electricidad limpia en 2040 junto con las renovables. Requiere inversión masiva: Para extender la vida útil de los reactores existentes (cuyo envejecimiento plantea serios interrogantes de seguridad y coste), construir nuevos reactores convencionales (EPR) y financiar tecnologías futuras como los SMRs (Small Modular Reactors) y la fusión (aún en fase experimental). Es cuestión de soberanía y liderazgo: Los Tratados permiten a cada país elegir su mix, y la UE debe mantener su liderazgo industrial en el sector nuclear. La crítica: Una apuesta arriesgada y desfasada Sin embargo, este planteamiento merece un examen crítico profundo: El mito de la “descarbonización rápida”: La nuclear es, en teoría, baja en carbono durante la operación. Pero: Plazos letales: Construir un reactor convencional nuevo lleva 15-20 años o más (véase los retrasos y sobrecostes de Flamanville, Olkiluoto o Hinkley Point). 2050 es la fecha límite para la neutralidad climática, no el punto de partida. La urgencia climática exige soluciones implementables ahora, no en décadas. Coste de oportunidad estratosférico: Los 241.000 millones de euros son recursos finitos. Invertirlos en nuclear desvía fondos cruciales del despliegue masivo y acelerado de energías renovables (eólica, solar), almacenamiento, redes inteligentes y eficiencia energética, tecnologías más baratas, más rápidas de instalar y con menor riesgo. Carbono oculto: La construcción, el minado y enriquecimiento del uranio, y la gestión eterna de los residuos, tienen huellas de carbono significativas, a menudo subestimadas. La quimera de los SMRs y la fusión: SMRs: Promesas incumplidas. Se venden como la panacea: modulares, más baratos, más seguros. Pero ninguno comercial está operativo en Occidente. Su viabilidad económica, la cadena de suministro, la aceptación pública y la gestión de sus residuos específicos son incógnitas gigantes. Apostar fuertemente por ellos hoy es financiar ciencia ficción con dinero real que falta para soluciones probadas. Fusión: Horizonte lejano. Presentada como la energía definitiva, pero ni siquiera se espera que aporte electricidad a la red antes de 2050. Incluirla como parte de la solución práctica para la descarbonización inmediata es, cuanto menos, ilusorio. El elefante en la habitación: Los residuos radiactivos: El PINC habla de inversión, pero ¿dónde está el plan concreto, financiado y aceptado socialmente para el almacenamiento geológico profundo definitivo de los residuos de alta actividad, que perduran durante miles de años? Este problema irresuelto, tanto técnicamente como en términos de gobernanza y responsabilidad intergeneracional, es la losa moral y práctica que la industria y la Comisión siguen evitando abordar con la transparencia y los recursos que merece. Competitividad cuestionable y dependencia: ¿Liderazgo o subsidio eterno? El sector nuclear europeo lleva décadas dependiendo de fuertes inyecciones de capital público (garantías de préstamos, tarifas subsidiadas). La promesa de “liderazgo industrial” choca con la realidad de una tecnología que no ha logrado ser competitiva en el mercado libre frente a las renovables. ¿Es sostenible esta dependencia perpetua del erario público?

France to build 'beyond' planned six new nuclear plants

News 24 January 7, 2024 France is set to build eight new nuclear plants on top of six already announced, the energy minister has said, arguing more reactors are needed to hit carbon reduction targets. A draft law set to be presented soon recognises that “we will need nuclear power beyond the six first European Pressurised Reactors” (EPRs) announced by President Emmanuel Macron in early 2022,…

Engineers, technicians… These profiles that the nuclear industry needs more than ever to revive

The Group of French Nuclear Energy Manufacturers (GIFEN) estimates at 30,000 the number of recruitments necessary for the construction of the six EPRs announced by Emmanuel Macron on Thursday. The announcement Thursday by Emmanuel Macron of the construction of six new EPR reactors – and the launch of a study for eight others – gave a smile to the nuclear industry. But it also poses a colossal…

Departmental week : Energy

Last week, all the students of the Energy Department went on a delightful trip to Normandy.  Not only was it an opportunity to visit companies but also a great opportunity to strengthen cohesion. 

On the first day, we went to La Hague and Flamanville to visit two sites. One was the storage site for nuclear waste, in which waste with medium radioactivity has been buried since 1966. The second was the new European Pressurized Reactor (EPR) located in the nuclear plant of Flamanville, which is supposed to help produce more energy with less waste, but it does not work despite the 21 billion euros invested.

On the second day, we visited the “Cité de la mer”. It was a really nice tourist visit . It was for us the opportunity to visit a nuclear submarine and to relax while watching some fishes. It is one of the favorite visits of the department !

On the third day, we visited Naval Group. It was a once-in-a-lifetime experience! It was the opportunity to see real submarines (which are classified as confidential for the general public). We were welcomed by an executive : Bruno Drant, head of safety in the Naval Group ! 

On the last day, we visited Safran's factory in Melun. It is a factory that produces civil and military aircraft engines. The factory is very modern and is designed to make the work of the workers as easy as possible. We discovered the different Safran projects, their commitments, career prospects and the advantages of working at Safran. Everybody enjoyed this visit !

Around 32 percent of people eligible to vote for the first time told newspaper Helsingin Sanomat (siirryt toiseen palveluun) (HS) they were certain they would be casting their ballot during next month's parliamentary elections.

The HS survey also found that 37 percent of respondents were 'most likely' going to use their democratic right for the first time, while 23 percent said they would 'most likely, or certainly not' be voting.

The newspaper explained that the most significant difference between the attitude of those who were sure to vote and those who were not was linked to the idea of voting as a civic duty. Lack of knowledge about the issues relevant to the election was also one of the reasons behind first-time voter hesitance.

The poll was conducted between January and February by polling firm Kantar and queried more than 600 people who were 18 years old, the legal voting age in Finland.

Aaltola: What is Finland's vision without Russia?

Finland should increasingly prioritise national security and geopolitics as well as reaching self-sufficiency, according to Director of the Finnish Institute of Foreign Affairs, Mika Aaltola.

Tampere-based Aamulehti (siirryt toiseen palveluun) reported on remarks Aaltola made in a discussion about security policy held at Tampere's Nokia Arena on Tuesday.

The paper pointed out that the talk was held less than three weeks away from Finland's parliamentary elections.

Aaltola said that Finland's future relationship with Russia must be based on deterrence.

"Putin despises the weak and exploits them, while he respects the strong. Relations with Russia must be based on national and collective deterrence. Putin sees us as weak. That we are raised with a silver spoon in mouth, far too lethargic to face a challenge like war," Aaltola said.

Russia has the capabilities of fighting a lengthy war, due to its greater capacity of casualties and readiness to switch to a war economy, Aaltola added, the paper explained.

"Putin was counting a lot on winter, but it was much milder than expected. Yet the mark of the war [in Finland] has been felt in electricity bills, at the gas pump, in inflation and in national concern," he said.

At the same time, the war has offered Finland more energy and economic independence, something that Aaltola said he would like policymakers to take into account.

"The elections must have a broad vision of Finland's development. They shouldn't be reduced to a debate about where to make cuts and how much. That is a rather bleak vision," Aaltola said, according to the paper.

"We should think about opportunities, possibilities and infrastructure. Tell people in Finland where this country is going. What is Finland's vision now that it is not built on Russia?"

OL3 soon fully online?

A new round of trials will test the Olkiluoto 3 nuclear reactor at full-scale power output on Wednesday evening, newspaper Ilkka-Pohjalainen (siirryt toiseen palveluun) reported.

Finland's newest nuclear reactor, OL3 has become notorious due to the length and number of delays, as the reactor was originally slated for completion in 2009.

Plant operator Teollisuuden Voima (TVO) announced that the facility was brought back online on Wednesday morning, following months of repair and maintenance work and more delays.

Regular electricity production at the plant is now estimated to begin 17 April, according to TVO, the paper reported.

The 1.6-gigawatt European Pressurised Water Reactor (EPR) was granted a construction permit in 2005 and was originally scheduled to be fully operational by 2009.

Why Jeff Bezos is going nuclear

Why Jeff Bezos is going nuclear

The nuclear new fad of the billionaires? For nearly fifteen years, Bill Gates has been financing TerraPower, an American company which aims to produce small reactors of 200 to 300 megawatts, six to eight times less powerful than an EPR. This time, it’s Jeff Bezos who starts. But not in the same niche as the founder of Microsoft. The boss of Amazon is not targeting the SMR reactor market (small…

The Flamanville EPR nuclear reactor will not be able to deliver its full power without major works.

According to our information, EDF has still not been able to identify the cause of the malfunction of the turbine in the Normandy reactor.  La Tribune Juliette Raynal, 04/07/25 After a doomed construction site, the Normandy reactor of the Flamanville EPR started up on December 21, twelve years behind schedule. Its entry into service does not signal the end of the problems, far from it.…
