Update: Japan workers edge closer to control of crippled nuclear plant
Workers at Japan's crippled nuclear plant began putting up equipment on Tuesday to allow the start of repairs to its cooling systems, key to bringing reactors under control after they were badly damaged in the March 11 quake and tsunami.
Soldiers moved to within 10 km (6 miles) of the Fukushima complex to search for those still missing following the disaster, the closest they have come to the plant since it began leaking radiation after the natural disaster hit.
Tokyo Electric Power (TEPCO) has said it may take the rest of the year to bring the nuclear plant back under control.
The company said it had begun constructing special tents at the entrance to turbine buildings so workers can move in and out. It is also installing fans with filters at the No.1 reactor to reduce radiation inside to one-twentieth of current levels within days.
"We want to suck out the air in the building and use the filter to remove radiation from the dust," TEPCO spokesman Junichi Matsumoto told reporters.
The magnitude 9.0 quake and massive tsunami that followed knocked out the cooling systems at the Fukushima Daiichi nuclear power plant, 240 km (150 miles) north of Tokyo, causing it to leak radiation.
It is Japan's worst disaster since World War Two and killed about 14,700 people, left some 11,000 more missing and destroyed tens of thousands of homes.
As the search for the missing continued, 560 Japanese Self-Defense Force troops began working within a 10 km radius of Fukushima Daiichi, the Defense Ministry said, the first time they have come so close since the nuclear crisis began.
