New government restrictions on the publication and broadcast of information about nuclear accidents brought angry criticism from Soviet journalists on the third anniversary of the Chernobyl disaster.

The new regulations released Wednesday appear to be an attempt to control increasing public anxiety initially sparked by the Chernobyl explosion April 26, 1986, and since fanned by a series of nuclear mishaps and near accidents. The Soviets have given it a name: radiation phobia, or radiophobia.The incidents include a Soviet nuclear submarine catching fire and sinking in the Norwegian Sea, a nuclear-powered icebreaker narrowly escaping a meltdown in Murmansk, and Armenia's nuclear power plant closed because it sits astride an earthquake zone.

The explosion of Chernobyl's No. 4 reactor killed 31 people.
