The amount of radioactive substances released from the reactor buildings has remained low since February. In November, a maximum of 10 million becquerels were leaking from the No. 1 through No. 3 reactors per hour, only one-sixth the discharge rate in December 2011.

But Fumiya Tanabe, a former chief research scientist at the now-defunct Japan Atomic Energy Research Institute, said persistent danger surrounds the plant's reactors.

"Despite the (officially declared) cold shutdowns of the reactors, the cooling functions have been maintained there with no knowledge of where the melted fuel lies and in what state," Tanabe said. "There is a risk of unforeseen circumstances arising if another major earthquake hits."

The probability of strong earthquakes striking eastern Japan within the next 30 years has markedly increased, according to experts.

The government's Headquarters for Earthquake Research Promotion released a series of upgraded "National Seismic Hazard Maps" on Dec. 21 that chart the probabilities of ground motion reaching lower 6 or higher on the Japanese seismic intensity scale of 7 over the period.

The probabilities rose remarkably from the previous release in 2010.

Ground motions were estimated from long-term earthquake occurrence probabilities along 110 major active geological fault lines across Japan and along ocean trenches.
