Tokyo Electric Power Co. said Monday it will release all available radiation data associated with its Fukushima No. 1 nuclear power plant, in response to criticism over its failure to swiftly announce leaks of radioactive rainwater into the sea. According to Tepco, the company had a policy of disclosing radiation information for contaminated water stored at the plant facilities if there is a risk of the water leaking into the sea. But this policy was not applied to radioactive rainwater that may leak into the sea via drainage ditches. The power utility has been criticized for not promptly releasing information about radioactive rainwater when it had data confirming leaks into the sea. At a press conference Monday, Managing Executive Officer Takafumi Anegawa said that the additional disclosures will include aerial radiation levels at the decommissioning work sites and contamination levels around plant buildings. The volume of such data is likely to be larger than that of the already disclosed, he said. The company did not specify when it will start releasing the additional data. On the same day, Tepco said it will appoint John Crofts, the head of the company’s internal regulatory organization, known as the Nuclear Safety Oversight Office, to the post of managing executive officer, effective Wednesday. Crofts, former director for safety assurance at Britain’s Atomic Energy Authority, will be the first non-Japanese to serve as managing executive officer of Tepco.
