Violent Aftershocks: New concerns about Japan's nuclear power plants

According to the new address severe earthquake in Japan, the anxious glances at the Onagawa nuclear power plant, in preparing the radioactively contaminated water in a cooling pond care. In the quake of 7.1 strength spilled a small quantity of the highly contaminated water from one basin for fuel rods.

In addition, leaks were found in eight places in the system, as the television channel NHK reported, citing the operator. The radiation around the kiln, 180 kilometers north of the Fukushima nuclear crisis, but is not increased. In several nuclear power plants in the northeast of the country there are problems with the current emergency care but it works.


The plants in Onagawa are off but since the devastating earthquake of magnitude 9.0 and the tsunami four weeks ago. The fuel elements but must be further cooled. But electricity is needed. The cooling continued for short periods after the aftershock, said the broadcaster NHK. Meanwhile, they work fine again.

Part of the external power supply are down, a stray energy source provides the facility to the report, but adequate. Problems are the technicians in the work of the operator Tohoku Electric Power in addition to the leak, especially a damaged part in a turbine building, which will control the pressure.

Going Nuclear Higashidori in Aomori Prefecture and Rokkasho reprocessing plant, the external power supply is interrupted, the news agency Kyodo reported. The emergency work fine in both places. The power plant disaster Fukushima One, the most by the quake and tsunami 11th March was heavily damaged, remained spared this time, however.

There was no new damage, as the operator Tepco said. Technicians are fighting there for weeks against an impending meltdown. The cooling of the reactors with water continue to function even after the quake, the agency Kyodo reported. It was, according to Tepco also initiated more nitrogen into the reactor housing to the block 1.
