JAKARTA, Indonesia - Indonesia says four nuclear reactors it plans to build near a volatile fault will be safe and more modern than the Japanese plant critically damaged by an earthquake and tsunami.

Ferhat Aziz, a spokesman for Indonesia's Nuclear Energy, says the nation of 237 million badly needs alternative energy sources.

The four reactors will be built on Bangka island by 2022. Bangka is near Sumatra, the heavily populated island where a 2004 earthquake caused the massive tsunami that killed 230,000 people in a dozen nations.

Aziz insists the Indonesian reactors will be safe, saying they will use technology 40 years more modern than the Fukushima plant leaking radiation in Japan.

Both countries are on the "Rim of Fire," an arc of active faults encircling the Pacific Basin.
