A robot deployed inside the ruins of a nuclear reactor at the tsunami-affected Fukushima Daiichi plant successfully retrieved a tiny sample of melted nuclear fuel on Thursday. The sample, equivalent in size to a grain of rice, was securely placed into a container, marking the completion of the mission. Tokyo Electric Power Company Holdings, the plant's operator, confirmed that the sample will undergo size and weight measurements before being sent to external laboratories for detailed analyses in the coming months.
The data obtained from this sample is crucial for devising a decommissioning strategy, developing necessary technology and robots, and understanding the progression of the accident, according to plant chief Akira Ono. While the initial sample is a significant milestone, further small-scale sampling missions will be required to gather additional data for the decommissioning process.
