• Japan's disaster draws attention to little-known U.S. nuclear insurance plan

    A little-known insurance pool in the United States that would provide insurance coverage for victims of nuclear reactor accidents occurring in the United States; the pool has been around for decades; Created under the Price-Anderson Nuclear Industries Indemnity Act of 1957 (Price-Anderson), the pool provides general liability insurance

  • Fifteen U.S. nuclear reactors are located in an active seismic zone

    There are 104 nuclear plants in the United States, and fifteen of them are located in what is known as the New Madrid Seismic Zone, a region defined by a fault line of the same name; the New Madrid Seismic Zone involves eight states, and it is an active earthquake area in the central United States that follows the Mississippi River between Missouri, Kentucky, Arkansas, and Tennessee; while the U.S. earthquake zone is active, scientists say the ingredients do not exist there for a Japan-style nuclear disaster; should a large seismic event strike this part of the country, seismologists offer Christchurch, New Zealand, rather than Japan as an example of what to expect. In February, Christchurch suffered a 6.3 magnitude quake and billions of dollars in losses

  • Germany's drive to end nuclear power serves as model for others

    Germany’s ambitious plan to wean itself from nuclear power and transition to renewable energy can serve as a valuable model for other countries seeking to do the same; nuclear power provides Germany with 23 percent of its energy; seven of its seventeen nuclear reactors will be taken offline; experts warn that the shutdowns could cause instability in the power grid and even blackouts; economists also say that the transition will be costly and result in higher energy prices for consumers; the government remains optimistic; renewable energy provides 17 percent of Germany’s energy needs and the Environment Ministry says that in ten years renewable energy will constitute 40 percent of all production

  • Zion's nuclear dry-cask storage solution

    In Illinois, 28,588 fuel assemblies, each containing a bundle of 200 rods and weighing about 600 pounds, are cooling in pools on the ground or above reactors — as in Japan; experts say they are “very inviting targets for terrorists”; moreover, “No one has come up with a solution to safely store this waste for 10,000 years into the future”

  • NRC: Not all equipment failures at U.S. nuclear plants are reported

    Companies that operate U.S. nuclear power plants are not reporting some equipment defects that could create safety risks, according to a new report; the Nuclear Regulatory Commission’s (NRC) inspectors found at least twenty-four instances where possible equipment defects were identified but not reported to the agency from December 2009 through September 2010; the NRC inspector general also raised questions in the report about the agency’s oversight, saying reporting guidelines for the nuclear industry are “contradictory and unclear”; unless the NRC takes steps to improve its reporting guidelines, “the margin of safety for operating reactors could be reduced” the report said

  • Nuclear countries glean lessons from Japan's disaster

    Japan’s effort to contain the escalating nuclear disaster reveals a series of missteps, bad luck, and desperate improvisation; what also emerges is a country that has begun to question some of its oldest values: Japanese have long revered the country’s bureaucratic competence, especially when it is contrasted with its political dysfunction; Japan has also proudly often chosen to go its own way and turn down outside assistance; other countries relying on nuclear power generation are trying to see whether the Japanese disaster holds lessons for them

  • Indian Point 50-mile evacuation plan unrealistic

    Located only thirty-five miles north of New York City, the most populous area in the United States, is the Indian Point nuclear reactor; safety officials are questioning the wisdom of operating a plant so close to New York City; a fifty mile evacuation radius around the plant would affect nearly twenty million people and some say evacuating that many people on short notice is a “fantasy”; NRC is currently conducting a thorough safety review of U.S. nuclear plants and the Indian Point reactor is one of seventeen under scrutiny; New York Governor Andrew Cuomo recently called for the plant to be shut down

  • U.S. reconsiders nuclear plant sites amid safety review

    Following the nuclear crisis that occurred in Japan as a result of a massive earthquake and tsunami, the United States is undergoing a thorough safety review of existing plants that may affect where new plants are located; President Obama ordered the Nuclear Regulatory Commission (NRC) to conduct a comprehensive safety review of all nuclear plants in the United States; observers are particularly concerned with the Indian Point nuclear power station located forty miles north of New York City; if an accident were to occur, up to twenty million people, including eight million in New York City, would have to be evacuated

  • New reactor design lessens risks

    One of the major vulnerabilities of the four Japanese reactors which failed as a result of the combined force of the earthquake and tsunami, was that they relied on active cooling systems that require electricity; if there is a power outage, and if diesel back-up generators stop working, water stops flowing into the reactor pool to keep the uranium rods cool; newer reactor design relies on a passive cooling system: water is suspended over the reactor housing, and if pressure within the system drops, this allows the water to fall into the reactor area, submerging it in enough water to keep it cool

  • Germany ends nuclear program

    Last Thursday German chancellor Angela Merkel declared that her government plans to close its nuclear power plants in a “measured exit”; the decision to end Germany’s nuclear power program was a result of the continuing nuclear crisis in Japan; some believe that Chancellor Merkel’s announcement is driven more by politics than safety concerns; recent polls show that 80 percent of voters are opposed to nuclear power; Merkel’s party faces close regional elections in states where nuclear plants are located; Switzerland, Venezuela, and China have also announced that they will suspend or delay plans to build new nuclear plants

  • U.S. nuclear program under greater scrutiny

    The ongoing nuclear crisis in Japan has caused countries around the world to reconsider its nuclear plans; Germany recently announced that it was ending its nuclear program, while Sweden, Venezuela, and China have all announced that they were temporarily suspending their nuclear programs to conduct safety reviews; lawmakers and engineers in the United States are also pushing for greater scrutiny of nuclear power plants; in its latest report the Union of Concerned Scientists sharply criticized the U.S. Nuclear Regulatory Commission (NRC) for not properly enforcing safety regulations at nuclear power plants;

  • Nuclear crisis worsening; growing radiation leaks at reactors nos. 3, 4

    The situation at the Fukushima Daiichi nuclear power plant appears increasingly dire, as efforts to cool overheating reactors have failed; Japanese military fire trucks are now spraying water at the plant’s no. 3 reactor; earlier efforts on Thursday to use helicopters to dump water on the rods have failed; the U.S. Nuclear Regulatory Commission chairman is particularly concerned about reactor no. 4 which houses spent fuel rods; spent fuel rods, placed in cooling tanks, are rapidly overheating as they are boiling away the water they are submerged in; the secondary containment unit at reactor no. 4 has been breached and radiation is now freely leaking out of the plant; high radiation levels are hindering efforts to repair the reactors

  • Cable connected to reactor no. 2, coolant pumps to be restarted

    Tepco, the operator of the stricken reactors, says — and the IAEA confirms — that its engineers have been able to reconnect a power line to reactor no. 2; the 1-km cable connects to the main power grid; restoring power should enable engineers to restart the pumps which send coolant over the reactor and into the pools where radioactive waste is stored; Tepco said the process of reconnecting power could take up to fifteen hours; senior IAEA official Andrew Graham said the situation at Fukushima had not deteriorated, but could yet do so. He described the situation at “reasonably stable”; the head of the IAEA, Yukiya Amano, is heading to Tokyo to be briefed by Japanese officials

  • Japan worst-case scenario unlikely to cause catastrophic radiation release: expert

    Two U.S. nuclear experts — both professors in the No. 1-ranked University of Michigan Department of Nuclear Engineering and Radiological Sciences — say that while exposed spent fuel rods at the failing nuclear reactors in Japan pose new threats, the worst-case scenario would still be unlikely to expose the public to catastrophic amounts of radiation; “The worst thing that could happen now is the fuel rods could be exposed to the air and that could be, then, down to our last barrier,” says one of the experts; “We could not have a recriticality, or a nuclear explosion. It’s physically impossible in this kind of system”

  • Japan's nuclear crisis increasingly dire

    Japan’s ongoing nuclear saga took a decided turn for the worse on Tuesday when a third explosion at a nuclear reactor may have cracked the containment unit protecting it, causing large amounts of radiation to leak out; the government requested assistance from the IAEA on Tuesday and teams were dispatched to help monitor radiation and human health; citizens within a thirteen mile radius of the Fukushima Daiichi power plant were evacuated and 140,000 residents within a twenty mile radius have been advised to stay indoors; officials also established a twenty mile no-fly zone around the power plant; officials in Tokyo reported that radiation levels were ten times their normal levels; experts say that these increased exposure levels do not pose an immediate threat to people, but the long-term effect remains unknown; the Tokyo Electric Power Company is considering using helicopters to pour cold water on top of overheating rooftops covering spent fuel rods; a small crew of fifty technicians at the badly damaged power plant is bravely fighting through high radiation levels and fires to contain the three reactors
