    NUCLEAR NATION: Following a devastating earthquake and tsunami in Japan, one of its nuclear power plants is on the verge of multiple meltdowns. Now, many in this country are asking whether U.S. plants can withstand such a disaster. Chief correspondent Tyler Suiters looks at how American nuclear plants could be vulnerable. THE MIX: HOW DO GOVERNMENTS HANDLE A NUCLEAR CRISIS? Thalia Assuras interviews U.S. Representative Marsha Blackburn (R-TN) for a preview of possible federal action in the wake of Japan's emergency. Blackburn sits on the House Energy and Commerce Committee, and her state is home to three working nuclear reactors as well as the only reactor under construction in the U.S. THE MIX: SAFETY AND REGULATION IN THE NUCLEAR INDUSTRY: Thalia speaks with Jarret Adams, spokesman for nuclear reactor manufacturer Areva, to find out how the nuclear industry can learn from Japan. Peter Bradford, a former NRC commissioner, thinks regulators are under pressure from Congress to keep plants running. And Arnie Gunderson, a nuclear engineer on a Vermont Yankee nuclear plant oversight panel, predicts many older plants wouldn't pass modern seismic evaluations. ENERGY THEN: FIRST NUCLEAR REACTOR: A newsreel from 1957 documents the opening of the nation's first privately-owned nuclear plant, in California, and touts the benefits of "power from a pioneer source." THE NEXT FRONTIER: "Mini nukes:" They're not something out of a spy thriller, they're a new generation of nuclear reactors that can power several thousand homes and might be safer than large reactors. Special correspondent Daniel Sieberg looks at this promising new technology that could make carbon-free energy cheaper, safer, and easier to build. THE HOT ZONE: UNDERWATER NUKES: France, which gets 80 percent of its power from nuclear, is looking at submerging small, modular reactors underwater as a way to increase safety. Some engineers there believe underwater reactors are less vulnerable to earthquakes or other natural disasters.

      Located in Eagle, Idaho The Blackhawk Project, LLC has designed and built a unique prototype wind turbine. The design is a marriage of helicopter roter head technology and wind turbines. The electrical generator was designed from scratch and uses proprietary technology that allows a lot of power to be generated at a very low speed.

                The Wild Horse Wind and Solar Facility, located in Central Washington, is Puget Sound Energy's second wind-powered electric generation facility. It is also the utility's largest wind farm with 149 turbines. Wholly owned by PSE, Wild Horse has the capacity to generate up to 273 megawatts (MW) of electricity. Construction began in October 2005, and was completed in December 2006, with a 22-turbine, 44 MW expansion completed in 2009. According to the American Wind Energy Association, one megawatt of wind power capacity is equal to the electricity needs of 225 to 300 average U.S. homes. Turbines and Towers - 149 wind turbine generators, spanning across 9,000 acres near Ellensburg, Washington. - Towers are 221 ft high at the hub, 13.2 ft wide at the base and 7.6 ft wide at the top. Towers weigh 104 tons. - Each turbine consists of 3-blades, each 129 ft long, 11.62 ft at the widest and 1.6 ft at the tip with each blade weighing 14,300 lbs. The rotor (blades, hub and nose cone) weighs 42 tons. - Turbine generators are V80-1.8 MW and V80-2.0 MW machines manufactured by Vestas, a Danish company. Each generator can produce 690 volts, which is stepped-up to 34,500 volts by an on-board transformer. The generator is housed inside a fiberglass "nacelle." - The generator and nacelle together weigh 69 tons. Total height with a blade fully extended is 351 ft and total weight is approximately 270 tons. These are the largest wind turbine generators in Washington State. - Each tower foundation reaches a minimum depth of 25 ft and a maximum of 32 ft depending on bedrock depth and takes an average of 100 to 260 cubic yards of concrete. - Each foundation requires 120 anchor bolts that span from the surface of the ground to the bottom of the foundation. A single 28 ft anchor bolt weighs approximately 150 lbs. - Rotors turn 15.5 rpm, turning clockwise (front view) with a rotor diameter of 264 ft, larger than a wingspan of a Boeing 747. - Turbines can produce electricity at wind speeds as low as 9 mph, reaching their peak of production at 31 mph and shut down at constant wind speeds of 56 mph. The prevailing winds are from the northwest. - 127 turbines are capable of producing 1.8 megawatts and 22 turbines are capable of producing 2 megawatts, for a total facility capacity of 273 megawatts.
