LONDON (Reuters) - New power supply cars to provide emergency electricity for systems that failed at Japan's Fukushima-Daiichi nuclear plant after a massive earthquake have arrived there, the World Nuclear Association said on Friday.
"The World Nuclear Association understands that three to four power supply cars have arrived and that additional power modules are being prepared for connection to provide power for the energy cooling system," said Jeremy Gordon, analyst at the London-based WNA.
The cables were being set up to supply emergency power. Other power modules were in transit by air, WNA added on its website.
Earlier, the WNA had said the situation at the plant was "under control," but a WNA source who did not want to be named said instead "the situation is improving."
The Japanese government warned that there could be a leak from the reactor, whose cooling system was damaged by the massive earthquake.
Tokyo Electric Power Co, which owns the facility, said pressure had built up inside the reactor after the cooling system was interrupted by the earthquake, the largest on record in Japan.
Pressure was set to be released soon, a move that could result in a radiation leak, officials said.
The Japanese government had declared an emergency situation around the plant as a precaution and evacuated residents.
