(UPDATE) JAKARTA, Indonesia — Southeast Asia's only nuclear power plant, completed four decades ago in Bataan, about 40 miles from the Philippine capital Manila, was built in the 1970s but left idle due to safety concerns and corruption. It has never produced a single watt of energy.

Now the Philippines and other countries in fast-growing Southeast Asia are looking to develop nuclear energy in their quest for cleaner and more reliable energy. Nuclear energy is viewed by its proponents as a climate solution since reactors don't emit the plant-warming greenhouses gases released by burning coal, gas or oil. Advances in technology have helped reduce the risks from radiation, making nuclear plants safer, cheaper to build and smaller.
