Chinese experts have inspected and declared safe nuclear facilities in the earthquake-devastated south-western province of Sichuan, state media said on Sunday.
The nuclear facilities "were confirmed safe and controllable after careful scrutiny," the official Xinhua news agency quoted government sources as saying, the dpa reported.
Several key military facilities related to nuclear research, plutonium production and warhead production are believed to be close to Sichuan's Mianyang city, which was one of the worst-hit areas after Monday's earthquake.
The environment ministry had ordered monitoring of radiation in case of leaks from the top-secret military nuclear facilities, although international experts believe they are built to withstand powerful earthquakes.
There are no nuclear power plants in Sichuan.
Monday's 7.9-magnitude earthquake destroyed hundreds of thousands of buildings, killed at least 30,000 people, and left tens of thousands of others buried under rubble or reported missing.
Some five million people in Sichuan were left homeless after the quake, and hundreds of dams and rivers were damaged, bringing the risk of flood to many towns and villages.
