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.

In July we held a co-ordinated leafletting session at some of the train stations through which trains carrying highly-reactive nuclear fuel rods from nuclear power stations (“nukiller trains”) go. This was moderately successful.

We are calling for a 2nd more extensive such action on September 27th. The aim is to leaflet people in the vicinity of the stations to inform them that such trains go through their local station and the dangers they represent.

It has been 3 ½ years since the triple meltdown in Fukushima, Japan, and the situation
over there is steadily sliding further out of control. The three melted-down reactors are
all leaking out into the environment, and efforts to deal with this constant leakage are
not getting anywhere. The mountains to the west funnel rain and ground water through
the site, and 400 tons of this water a day are estimated to enter the reactor buildings, mix
with the reactor fuel, then head out into the Pacific Ocean – every single day since the

In May 2014 Noam Chomsky gave a lecture at Durham University during which he quoted American General Lee Butler:
'we had so far survived the nuclear weapons era “by some combination of skill, luck, and divine intervention, and I suspect the latter in greatest proportion.”.” (1)

It is now two years since Kick Nuclear and Japanese Against Nuclear [ JAN UK ] started the weekly picket of the Japanese Embassy and TEPCO [ The Tokyo Electric Power Company ]. We will not be celebrating this anniversary.

We repeat exactly what we said last year upon the first anniversary of the picket.
