Disaster workers are preparing to inject nitrogen into a reactor containment vessel at the Fukushima Daiichi nuclear power facility to prevent stored-up hydrogen from causing an explosion at the plant’s No. 1 reactor. As the nuclear crisis continues to unfold, it has been revealed that the owner of the stricken plant, Tokyo Electric Power Co., proposed building two new reactors at Fukushima just as the crisis spiraled out of control late last month. The proposal was submitted to local officials on March 26 — just two weeks after a massive tsunami set off the world’s worst nuclear crisis in 25 years. Tokyo Electric Power says the proposal was drawn up before the disaster and that company officials forgot to withdraw it.
