Let us hope that the people of our country begin to understand the utter greed of the foreign companies that wish to make the UK a formidable nuclear power.
E-on, RWE and EDF you are parasites that wish to lay your eggs in our green and pleasant land.
We as the British people must stand up to you!
I guess nuclear will be off your agenda and now you will wish to develop renewables in the UK?
Japanese authorities have declared a state of emergency at two nuclear power plants, after Friday's devastating earthquake caused malfunctions.
Cooling systems inside several reactors at the Fukushima 1 and 2 power plants have stopped working properly, leading to a build-up of pressure.
Thousands of people have been ordered to evacuate the area near the plants.
Technicians are starting to release vapour to lower the pressure in some of the reactors.
Some of the released gases could be radioactive, but officials insisted the procedure would pose no risk to the public.
Radioactivity levels in the control room of the Fukushima 1 plant were reportedly running at 1,000 times normal.
The earthquake knocked out the power supply to the plants, which then automatically shut down.
But it seems that back-up generators at Fukushima 1 designed to power the plant's basic functions also failed.
Two reactors at the Fukushima 1 plant were left without sufficient cooling.
And officials later said they were unable to control the cooling systems in three reactors at Fukushima 2 plant, 11km (seven miles) south of Fukushima 1.Wind factor
Under Japanese law, an emergency must be declared if a cooling system fails, if there is a release of radiation, or if there is a dangerous level of water in the reactor.
Prime Minister Naoto Kan declared the emergency. He announced the evacuations after visiting the plant.
Defence officials said troops trained in chemical disasters had been sent to the plants in case of a radiation leak.
Earlier, the authorities say they are taking wind direction into account when planning the release of radioactive vapour, which they insist would not be in quantities big enough to affect human health.
"It's possible that radioactive material in the reactor vessel could leak outside but the amount is expected to be small and the wind blowing towards the sea will be considered," Chief Cabinet Secretary Yukio Edano told a news conference.
The six reactors at Fukushima 1 came online in the 1970s; Fukushima 2 has four reactors, built during the 1980s.
All nuclear facilities in Japan are designed to withstand earthquakes.
But experts say there appears to have been multiple failures at the Fukushima facilities, raising serious questions about the safety of Japan's reactors.
The reactors at Fukushima 1 are Boiling Water Reactors (BWR), one of the most commonly used designs, and widely used throughout Japan's fleet of nuclear power stations.
Heat is produced by a nuclear reaction in the core, causing the water to boil, producing steam. The steam is directly used to drive a turbine, after which it is cooled in a condenser and converted back to water. The water is then pumped back into reactor core, completing the loop.
In total, the country has 55 reactors providing about one-third of the nation's electricity.
