Japan nuke plants ordered to beef up readiness

Reverberations jolted Japan on Saturday hours after the country's nuclear security agency prepared plant operators to beef up their earthquake-preparedness systems to put off a reappearance of the nuclear crisis roiling the county north of Tokyo.

There were no preliminary reports of damage from the magnitude-5.9 reverberations, and there was no risk of a tsunami similar to the one last month that crippled the Fukushima Dai-ichi nuclear plant, causing Japan's worst-ever nuclear plant blow. Japan has been hit by a string of slighter quake since the scale 9.0 earthquake hit the country on March 11.

In the meantime, the newspaper Asahi Shimbun, citing no sources, reported that a top secret plan to take to pieces Tokyo Electric Power Co., which runs the radiation-leaking Fukushima plant, was circulate within the government.
