Westinghouse Electric is expected to sign a multi-billion-dollar deal to build four nuclear reactors in eastern China. That puts China at the forefront of a global trend toward nuclear power. A recent study predicts energy consumption will rise by more than 50 percent over the next 25 years. China is now the world's second-largest energy consumer. It plans to spend $50 billion on nuclear reactors in the next decade. India hopes to ramp up its nuclear power too, if it can finalize a deal with Congress to buy nuclear technology from U.S. companies. But fears about nuclear safety resurfaced last week after an earthquake in Japan caused a radiation leak at the world's largest power plant.
