The particles was extracted from the Fukushima Prefecture plant’s No. 2 reactor beneath the facility firm’s first trial removing that began in September and was accomplished on Nov. 7. It has been analyzed at a JAEA analysis facility in Ibaraki Prefecture.
The collected particles is about 9 millimeters lengthy and round 7 millimeters vast, and weighs 0.693 gram. Its radiation stage measured 1 to 2 centimeters away stood at 8 millisieverts per hour, the JAEA mentioned.
In addition to uranium, iron and zirconium, utilized in a pipe protecting nuclear gasoline, have been detected from the pattern, the company mentioned. It additionally discovered the within of the extracted particles to be hole.
The evaluation on the JAEA and different analysis services will proceed for about six months to at least one yr to assemble data to be used in analysis towards full-fledged efforts to take away particles from the nuclear reactors.
The pattern may even be analyzed on the SPring-8 giant synchrotron radiation facility in Hyogo Prefecture to search out out its crystal construction in additional element.
TEPCO mentioned it’ll begin the second trial removing work as early as round March subsequent yr.
