EDF are preparing to build new nuclear reactors at Hinkley which could help growth and create 25,000 jobs, but the deal is in the balance.
Google Earth's all-seeing cameras have collected new images of a nuclear test site in North Korea.
Ministers will delightedly make their announcements later. But one question remains - how much subsidy will new nuclear receive?
Police have arrested 47 demonstrators staging a blockade at a naval base in protest against the nuclear missiles stored there, STV reported.
The Scrap Trident coalition wants Scotland to be allowed to "lead the way to a world free of nuclear weapons" and more than 100 of its supporters are demonstrating at Faslane Naval Base, in Argyll, the home of the UK's Trident weapons system.
Around 20 protesters chained themselves to the north gate of the base while sitting or lying on the ground, and eight people are "locked on" to the south gate.
Police issued a warning to the group at the north gate then officers started using cutting equipment to separate them.
Iran has told the UN's International Atomic Energy Agency that an earthquake that hit the country today did not damage the Bushehr nuclear power plant, the IAEA said.
"Iran has informed [the IAEA's Incident and Emergency Centre] of the event, reporting that there has been no damage to the Bushehr Nuclear Power Plant and no radioactive release from the installation," the UN agency said in a statement.
US envoy to the United Nations, Susan Rice, has said that new sanctions against North Korea under consideration by the Security Council are "exceptional" in their breadth and scope.
She said the draft resolution tabled by the US "will significantly impede North Korea's ability to develop further its illicit nuclear and ballistic missile programmes".
She added that the sanctions would target the "illicit activities of North Korean diplomatic personnel", "banking relationships" and "illicit transfers of bulk cash" in addition to "new travel restrictions".
The UN health organisation is due to publish its findings on the health impact of the Fukushima nuclear disaster in Japan today.
The in-depth report will give the World Health Organisation's assessment of risks from radiation exposure to people all over the world, as well as in the immediate vicinity.
Three reactors at Japan's Fukushima Daiichi nuclear plant experienced meltdowns after a 15-metre tsunami cause by a major earthquake disabled the plant's power supply.
No-one has died as a result of the accident, but more than 100,000 people were evacuated to avoid exposure to radiation.
The environmental network Friends of the Earth has responded to Centrica's pullout of the UK's nuclear rebuilding programme, saying new power plants would be a "waste of money":
– Friends of the Earth's Andrew Pendleton
The nuclear dream is becoming an economic nightmare. Centrica's decision to pull out of building new reactors is further evidence of the escalating cost of this form of energy.
Billions of pounds of taxpayers' money has already been spent trying to deal with the nuclear industry's toxic legacy and billions more will be wasted if we press ahead with new nuclear power plants.
Ministers must focus on the real solutions to the energy challenges we face - slashing energy waste and developing the enormous potential for safe, clean British energy from the wind, waves and sun.
EDF says it "respect Centrica's decision" to pull out of new nuclear.
It says the Contract for Difference - in other words, indirect subsidy - is the key to getting new builds.
Centrica pulling out certainly puts more pressure on the government to sweeten the deal for EDF and other potential investors in new nuclear.
The Department of Energy and Climate Change insists the Centrica decision is "nothing to do with government policy". It certainly gives them a policy problem though.
Centrica has released a statement saying increasing costs and delays prompted the company to abandon plans to partner EDF in a UK nuclear rebuilding programme:
– Sam Laidlaw, Chief Executive of Centrica
Since our initial investment, the anticipated project costs in new nuclear have increased and the construction timetable has extended by a number of years.
"These factors, in particular the lengthening time frame for a return on the capital invested in a project of this scale, have led us to conclude that participation is not right for Centrica and our shareholders.
Centrica has withdrawn from the UK's nuclear re-building programme. It's not a surprise, but it's a very big blow for new nuclear.
Sources at the company believe the economics have changed so much that what looked a good deal is not any more.
