At a Tokyo job fair for the atomic energy industry on March 4, Kenta Kakitani, a graduate student at the University of Tokyo, hopes to some day become a nuclear plant design engineer.

But Kakitani may be a rare breed in Japan, where nuclear businesses have seen a serious shortage of new talent since the March 11, 2011, meltdowns at the Fukushima No. 1 power plant, the world's worst nuclear disaster since Chernobyl in 1986.

"It seems that the nuclear power industry has lost much of its popularity because it is seen as in decline and is suffering a negative image from having to decommission crippled reactors," said Kakitani, 24, who majors in nuclear engineering.
