NARAHA, Japan — In this small farming town in the evacuation zone surrounding the stricken Fukushima Daiichi nuclear power plant, small armies of workers in surgical masks and rubber gloves are busily scraping off radioactive topsoil in a desperate attempt to fulfill the central government’s vow one day to allow most of Japan’s 83,000 evacuees to return. Yet, every time it rains, more radioactive contamination cascades down the forested hillsides along the rugged coast.
Nearby, thousands of workers and a small fleet of cranes are preparing for one of the latest efforts to avoid a deepening environmental disaster that has China and other neighbors increasingly worried: removing spent fuel rods from the damaged No. 4 reactor building and storing them in a safer place.
The government announced Tuesday that it would spend $500 million on new steps to stabilize the plant, including an even bigger project: the construction of a frozen wall to block a flood of groundwater into the contaminated buildings. The government is taking control of the cleanup from the plant’s operator, the Tokyo Electric Power Company.
