The Stop Nuclear Power Network is a UK-based non-hierarchical grassroots network of groups and individuals taking action against nuclear power and its expansion and supporting sustainable alternatives. We encourage and seek to facilitate nonviolent direct action, as well as more conventional forms of campaigning.

No to nuclear power in Britain

The origin of Britain's civil nuclear programme is closely linked with nuclear weapons. The first reactor - the "Windscale Piles" at Sellafield, began producing plutonium for nuclear weapons 1950. Britain's first commercial reactor - Calder Hall at Sellafield - was a dual-purpose reactor, with the main purpose being the production of plutionum for Britain's nuclear weapons. The same applies to the second commercial reactor at Chapelcross.

Later reactors were primarily built for the production of electricity, and in April 1995 the UK Government announced that all production of plutonium for weapons purposes had ceased.

At its peak in 1997, about 26% of Britain's electricity was generated by nuclear power. This has now gone down to less than 20%, and only 16% in 2009.

At present, the government wants to build new nuclear power stations at eight sites - all of which are existing nuclear sites. However, opposition to nuclear power is again growing. This website provides information for the growing anti nuclear power movement in Britain, with a special focus on nonviolent direct action against nuclear power.

This map gives an overview of nuclear power stations in Britain.

Critics of the atomic phase-out said energy emissions, costs and imports would all rise. They were wrong.

With the UK taking another step towards supporting new nuclear power on Tuesday – at either no extra cost to the consumer if you believe ministers, or substantial cost if you believe most others – it's worth taking a look at what actually happens when you phase out nuclear power in a large, industrial nation.

Questions have been bubbling recently over how safe Japan’s stricken Fukushima Daiichi nuclear plant—in particular the pool atop Unit 4, where some 1,535 fuel rods are stored—would be if another big earthquake hit.

The Nuclear and Industrial Safety Agency and Tokyo Electric Power Co. were aware at least by 2006 that the Fukushima No. 1 nuclear plant was at risk of having its power knocked out by massive tsunami, NISA officials said Tuesday.

It was as inevitable as cherry blossoms blooming in springtime: sooner or later, Japan had to nationalize the Tokyo Electric Power Company (TEPCO), the owner of the ruined Fukushima Daiichi nuclear plant. Today the government announced a ¥1 trillion (US$12.5 billion) plan to bail out the country’s largest utility, and at least temporarily take control.

MOSCOW - More than a year since the catastrophic nuclear and radiation disaster at Japan’s Fukushima Nuclear Power Plant, concerns loom ever larger over the site as experts warn with increasing worry of the unstable condition of the cooling pond at Unit 4, where spent nuclear fuel holds ten times the amount of radioactive cesium that was blown into the atmosphere with the 1986 reactor explosion at Chernobyl. Russia would be well served to join their call for action – will it?
