Fukushima Operator Prepares to Lift 20-Ton Debris From Fuel Pool via The Wall Street Journal

The latest challenge at the Fukushima Daiichi nuclear power plant is to remove a 20-ton piece of debris from a pool holding over 500 spent fuel rods.

More than four years after the plant was hit by a massive earthquake and tsunami, Fukushima Daiichi’s operator Tokyo Electric Power Co.9501.TO -2.67% said it would start work on the critical task this week using a specially designed crane.

“The debris will be pulled out using two cranes, but we had to create a specially designed hook with a unique shape for it to securely hold on to the object,” a Tepco spokesman told Japan Real Time on Monday.

The object is what remains of a fuel handling machine originally located above the surface of the water. The debris is preventing Tepco from removing the spent fuel rods to a safer location. It is the largest object requiring removal inside the power plant’s reactor No. 3, according to the company.

The removal will be conducted at the slowest possible speed to ensure safety. The pool’s water level, as well as any signs of a jump in radiation levels, will be monitored closely with multiple cameras during the procedure. The debris must be lifted so that it won’t swing or cause damage to the spent fuel pool’s gates.
