Tokyo (cnn) - a brief video clip published Saturday captures the massive tsunami that paralysed Japan Fukushima Daiichi plant, showing the wall of water that slammed shut at the facility and created an ongoing crisis.

The video shows giant wave generated by the earthquake of March 11 historic crashing on the dike of the plant and engulfing the installation, with a sheet of rising higher than buildings spray this House six reactors. Tokyo Electric Power, the factory owner, told journalists that the wall of water was likely 14 to 15 metres (45 to 48 feet) higher than the normal level of the seas - easily an overwhelming seawall of 5 meters of the plant.

The video was shot from high ground approximately 900 metres south of the plant by a worker who evacuated before the shock of the tsunami, the Tokyo Electric Power Company stated by releasing the clip of six seconds.

Photos published by the society showed broken Windows, scattered papers and ceiling tiles that hang in any annex Office now empty factory. Two workers were killed in the basement of the turbine of the No. 4 reactor plant, when the tsunami hit, and their bodies were found only last week.

The tsunami was knocked unconscious generators and pumps needed to cool the three reactors of plant operations after the earthquake of magnitude 9, leaving engineers struggling to prevent a disaster larger than these units of overheating of radioactive nuclei. In response to the earthquake, Japanese regulators has published more stringent standards for the nuclear plants emergency power Saturday.

Plants must have two diesel generators as backup for each unit of reactor power, said Hidehiko Nishiyama, the chief spokesman for the nuclear and industrial safety agency of Japan. Current regulations require that a generator unit.

Plant workers began to lay the pipes at the level of the ground between the reactor units and processing of radioactive waste where engineers hope pump contaminated water which has been build, Sakae MutoDirector of the division of nuclear energy of the utility, said Saturday.

Workers were slope of hundreds of tons of water per day in reactors in an effort to keep them cool until normal traffic systems can be restored. The No. 2 reactor is supposed to be highly radioactive water leaks, of which some were spill in the Pacific until Wednesday, while the basements flooded in turbine of all plants are three units makes it impossible to restore powersaid officials of the company.

And engineers have been added nitrogen in the envelope of primary containment reactor No. 1, a movement to counter a buildup of flammable hydrogen in the unit. Inert nitrogen displaces oxygen that can fuel an explosion, as the explosion of hydrogen which blew apart buildings surrounding units 1 and 3 in the days following the earthquake.

The accumulation of hydrogen is a symptom of fuel rods damaged in the reactor core. But the Tokyo Electric called the chances of the explosion of an another "extremely low". And new equipment allowed engineers to increase the concentration of nitrogen from 98% to 99% Saturday, Nishiyama said.

Workers returned to the factory of Friday following a replica of magnitude 7.1 late Thursday night that forced them to evacuate for about eight hours, said Japanese authorities. Replica not believe have inflicted further damage to the plant, Tokyo Electric and Agency Security reported Friday.Hiroo Saso and Gen Shimada contributed to this report by CNN.
