Four fuel storage pool at Japan's tsunami-damaged nuclear power plant have fresh cooling water for nearly 20 hours due to a power outage, the plant operator said Tuesday, still improve a facility vulnerability concerns in temporary equipment built to run on.
Tokyo Electric Power Company, the first plant in Fukushima pool temperature in a safe range, at least four days without fresh cooling water, the pool would remain safe. The utility reactor was not affected, and no other abnormal findings.
Tokyo Electric Power Company workers scrambling to find the cause and fix the problem.
One possible reason for case workers is fixed in the past three switches, they suspect that the problem and the utility to prepare a backup system, maintenance and does not solve the problem, the Tokyo Electric Power Co. spokesman Masayuki Ono told reporters.
He said: "If the worst the worst, we have a backup water injection system," Ono said.
On March 11, the Japanese earthquake and tsunami destroyed the plant's power and cooling systems, the three reactor core melting and overheating of the fuel storage pool.
Blackout is a major test of TEPCO display, if it is to learn any lessons from the disaster. Tokyo Electric Power Company, has repeatedly faced cover up the scandal, has been criticized in the local media said on Tuesday the waiting time of the blackout.
Ono admitted the plant is vulnerable.
"Fukushima Daiichi is still running in makeshift equipment, we are trying to switch to something more durable and reliable, this is ideal," he said. "Taking into account the situation of the equipment, we may push a little too hard."
Ono said the utility does not immediately switch to the backup cooling system did not find and fix, because doing so may result in duplicate. An alternate cooling system, but there is no external power backup.
The regulatory bodies have been previously proposed temporary equipment concern, and urged plants to switch them to a more long-term arrangements. The operators delete melt deadly radioactive fuel from the reactor plant before retiring, officials said, may take 40 years.
The government's chief spokesman, Yoshihide Suga, intended to allay concerns.
"In a sense, we have to take measures, fearing that leave no room," Suga told reporters at a regular press conference.
Plant command center 31 January 18 19:00, suffered a brief power outage. Power quickly restored to the command center, but not into the fuel pool pumping equipment.
The four pool temperature increased slightly, but far less than the utility of the target temperature was controlled at 65 degrees Celsius, the Tokyo Electric Power Company said.
