Workers of the damaged Fukushima nuclear plant in Japan have alleged its operator Tokyo Electric Power Company (TEPCO) have been lying about the true state of meltdown crisis in the facility.

Apparently, the stricken facility continues to give off manifestations of its crippled state.

"Steam came out of the Reactor 3 building the other day," Fujimoto-san, a 56-year-old decontamination worker at the Fukushima nuclear plant, told ABC News.

What's more worse, TEPCO continues to hide things and information under the blanket. "When it came out, TEPCO didn't even tell us. I found out about it on the TV news after I got home from work," Mr Fujimoto-san said.

On Thursday, Prime Minister Shinzo Abe has been forced to step into the Fukushima nuclear plant meltdown crisis after it has been confirmed that the facility had been leaking 300 tonnes of radioactive water per day into the ocean since it got destroyed by a tsunami in March 2011.

Still, with its alleged lies, the reported 300 tonnes of radicoactive water per day could still be underestimated, the Examiner said. "As a consequence, the entire Pacific Ocean will become uninhabitable for marine life in a few years."

TEPCO, it seemed, had known the leakage all along since that fateful day in March two and a half years ago but refused to tell the truth and continued to hold the world hanging for information.

"I believe it's been leaking into the ocean from the start of the crisis two-and-a-half years ago," Suzuki-san, a former Fukushima site foreman who had worked for TEPCO for 12 years, told ABC.

"TEPCO probably knew this but did nothing because they didn't want to cause an outcry," he said.

Meantime, Mr Fujimoto-san said that apparently, not all reactors at the crippled Fukushima nuclear plant have been tested for safety and efficiency after the incident.

"There are still reactor buildings we haven't gotten into yet," he said.

"So there's always the possibility of another explosion, and if that were to happen, we - the workers - would be the first victims. I fear that a lot," he added.
