Tokyo Electric Power Co (Tepco) has announced on Thursday new spots of high radiation have been found fuelling fears of further contaminated water leakage.
After the operator of the crippled Fukushima Daiichi power plant announced earlier this week that 300 tonnes of highly radioactive water has seeped from one of the storage tanks probably through a malfunctioning valve, concerns have been raised whether Tepco actually has the situation under control.
In an additional announcement made today, the company revealed having detected radiation levels of 100 millisieverts per hour and 70 millisieverts per hour respectively, near two tanks in a different part of the plant.
Although no puddles were found nearby and there were no noticeable changes in water levels in the tanks, the possibility of stored water having leaked out cannot be ruled out, a Tokyo Electric spokesman said.
Japan’s nuclear watchdog has expressed its concern previously whether Tepco is capable of dealing with the situation at the wrecked power plant and the International Atomic Energy Agency (IAEA) said it is taking the situation at Fukushima seriously and is ready to step forward and help if asked.
Japan’s Asian rival China claimed to be shocked by the revelations and urged Japan to provide information in a timely and accurate manner.
The Fukushima Daiichi power plant, located north of Tokyo, was damaged in March 2011 during a severe earthquake that caused fuel-rod meltdown in three reactors.
The accident, considered the world’s worst nuclear disaster since the explosion at Chernobyl in 1986, is expected to take decades to clean up.
