Énergie nucléaire : « SMR » (petits réacteurs modulaires)

by Connaissance des Energies, 29 avril 2019

  • Les Small Modular Reactors (SMR) sont de petits réacteurs nucléaires réalisés en usines sous forme de modules.
  • Leur puissance varie généralement entre 10 et 300 MW.
  • Le déploiement des SMR est envisagé pour produire de l’électricité, en particulier dans des sites isolés, mais également pour des applications non électrogènes : chaleur, dessalement, production d’hydrogène, propulsion, etc.
  • Fin 2018, on dénombre une cinquantaine de projets de SMR, avec de nombreuses technologies à l’étude.

Nuclear Power Can Save the World

by J.S. Goldstein et al., April 6, 2019

As young people rightly demand real solutions to climate change, the question is not what to do — eliminate fossil fuels by 2050 — but how. Beyond decarbonizing today’s electric grid, we must use clean electricity to replace fossil fuels in transportation, industry and heating. We must provide for the fast-growing energy needs of poorer countries and extend the grid to a billion people who now lack electricity. And still more electricity will be needed to remove excess carbon dioxide from the atmosphere by midcentury.


Nuclear power excluded from EU’s green investment label

by C. Stam & A. Prager, April 3, 2019 in EurActiv

The text voted in Parliament also excludes fossil fuels and gas infrastructure from the EU’s proposed green finance taxonomy, which aims to divert investments away from polluting industries into clean technologies.

In a bid to prevent “green-washing”, the Parliament text also requires investors to disclose whether their financial products have sustainability objectives, and if they do, whether the product is consistent with the EU’s green assets classification, or taxonomy.

While activists applauded the move, they said the classification voted by the European Parliament was too narrow and applies only to a limited set of recognisable green assets, such as wind and solar power companies.

“Brown list” rejected

An amendment to publish a “brown list” to name and shame investments seen as damaging for the environment was rejected by Parliament.

‘L’impossible équation des écologistes’

by Prof. Ch. Leclercq-Willain, 5 avril 2019 in ScienceClimatEnergie

Depuis plusieurs années un des combats mené par les écologistes dans différents pays européens (Allemagne, France, Belgique, ..) fut et reste celui du nucléaire mené actuellement en parallèle avec celui de la réduction des gaz à effet de serre (GES). Les « verts » allemands ont obtenu la fermeture de presque toutes les centrales nucléaires et l’Allemagne a toujours une exploitation importante de centrales gaz-charbon. L’Allemagne est ainsi le plus grand émetteur de CO2 en Europe. Il en est de même des pays de l’Est et de la Russie qui exploitent essentiellement des centrales gaz-charbon. En Belgique, la fermeture définitive des centrales nucléaires est prévue pour 2025.

China-built nuclear reactors may enjoy home advantage as delays and costs stymie foreign competitors

by Bloomberg, April 2, 2019 in SouthChinaMorningPost

China’s home-grown nuclear technology is gaining favour in the battle for the nation’s next generation of reactors, according to a state-owned developer, as it sought to recover from delays and cost blowouts from imported designs.

China’s reactor, known as the Hualong One, will be faster and easier to repair and maintain than competing foreign designs because it will be made at home, according to Chen Hua, chief executive officer of China National Nuclear Power company (CNNP), which builds and operates nuclear power projects.

“We prefer the Hualong One,” Chen said on Monday at a nuclear energy conference in Beijing.

The global nuclear industry has been awaiting a revival in China after cost overruns and stricter regulation after the 2011 Fukushima disaster in Japan stalled the approval and construction of more units.

Climate Scientists Reject Wind And Solar, Demand Nuclear-Powered Future

by Stop These Things, November 20, 2108 in ClimateChangeDispatch

In the climate alarmists’ worldwide crusade against carbon dioxide gas, only the most delusional still believe that wind and solar power add anything to their arsenal.

As we have said repeatedly, nuclear power is the only stand-alone power generation source which is capable of delivering power on demand, without CO2 emissions being generated in the process.

Perversely, notwithstanding that Australia is in the top three uranium exporters, it’s the only G20 country with a legislated prohibition on nuclear power generation…

Global nuclear power capacity expected to reach 536GW by 2030

by GlobalData Energy, October23, 2018

Nuclear technology is a major base-load power-generating source and accounted for 10.5% of global power generation in 2017 as per GlobalData, a leading data and analytics company.

The nuclear power sector is growing in many countries as demand for electricity increases. The company’s latest report ‘Nuclear Power – Thematic Report’ reveals that some 31 countries are currently operating nuclear reactors for their electricity generation. Countries with significant nuclear power capacity are the US, France, Japan, China, Russia, South Korea, Canada, and Ukraine, with more than ten gigawatts (GW) installed capacity each. Germany, the UK, Sweden, India, Spain, Belgium, and Taiwan have five to ten GW installed nuclear power capacity each.

The global cumulative installed nuclear power capacity in 2010 was 376GW, of which more than 100GW was in the US alone.
