Many things have been said about last September's fatal nuclear accident at the JCO Co. uranium processing plant in Tokai, Ibaraki Prefecture.

But six months after Japan's worst nuclear accident, little has actually been accomplished to alleviate public concerns about the safety of atomic energy or to try to pinpoint who may be criminally liable for the accident.

The government set up and revised legislation in December to place more responsibility on the central government and nuclear facility operators for disaster prevention and crisis management, but a specific plan of action has been slow in coming.
