A consortium of Western utilities and a nuclear reactor designer have submitted a proposal to the U.S. Department of Energy to build a small nuclear reactor to meet future demand for carbon-free power. The proposal seeks millions of dollars in grant money to walk the project through the vigorous licensing and permitting process.
On 60 Minutes Overtime, producer Graham Messick describes one of his favorite news stories. While on the lookout for a story on nuclear smuggling, the 60 Minutes team stumbled upon an attack at the Pelindaba Nuclear Research Centre in South Africa.
Southern California Edison, operators of the San Onofre nuclear power plant, are laying off 600 employees as the troubled facility begins to shut down for good. The Orange County Register says nonunion employees will begin receiving pink slips in about two months.
A reactor at the Diablo Canyon nuclear power plant has been shut down so crews can perform repairs on equipment after a small leak was detected. Pacific Gas & Electric Co. said the leak was discovered Wednesday in Unit 1 during routine maintenance, and that it was contained within the plant.
Shareholders angry at the utility company behind Japan's nuclear catastrophe peppered executives with questions Wednesday about leaking radioactive water and demanded a phase-out of atomic power. Fifteen such motions from shareholders were defeated at an annual shareholders' meeting.
In a motion filed with the Public Utilities Commission, the state Division of Ratepayer Advocates says California regulators should immediately slash hundreds of millions of dollars from utility customer bills because the San Onofre nuclear power plant is being shut down permanently.
An underground tank holding some of the worst radioactive waste at the nation's most contaminated nuclear site might be leaking into the soil. The U.S. Energy Department said workers at Washington state's Hanford Nuclear Reservation detected higher radioactivity levels under tank AY-102 during a routine inspection.
Taylor Wilson has been dreaming about being a nuclear scientist since the age of 11 when he asked to build a nuclear reactor in his parents' garage. Now 19, Wilson has a number of scientific discoveries under his belt and hopes to revolutionize nuclear power.
Iran's state TV says a site in southern Iran has been selected for a planned new nuclear research reactor. There has been no timetable announced for the proposed plant, which would be similar to a research reactor in Tehran that produces medical isotopes. Iran's lone energy-producing reactor is in the Persian Gulf port of Bushehr.
