Japan asks for US help in nuclear crisis

Yamagata, Japan: Japan has reached Friday to the United States for help in controlling the crisis at its nuclear complex dangerously overheated, while the head of the UN Atomic Energy Agency has called the disaster a race against time watch that requires global cooperation.
Complex shapes, fire trucks sprayed the military reactors in trouble for a second day, with tons of water arcing over the installation in desperate attempts to turn the units and prevent a collapse that could dump unsafe levels of radiation.

The unfolding crisis led to shortages of electricity in Japan, forced to close factories, has sent shock waves of global manufacturing and caused a fall in Japanese stock prices.

"I think they are racing against time," he said of efforts to cool the assembly.
A week after the earthquake and tsunami - which killed more than 6,500 dead and 10,300 more missing - emergency crews face two challenges in the nuclear crisis reactor cooling where energy is produced, and pool cooling adjacent spent fuel when used nuclear fuel rods are stored in water.
