Japan’s Engineers Have Laid Power Cable

Japan’s engineers have managed to set up a power cable to reactor 2 that would enable them to restart pumps, which send coolant over the reactor at Fukushima nuclear plant.

Emergency workers at Fukushima nuclear plant have been struggling to prevent fuel in the reactors from overheating as the power supply and back-up generators were damaged by the Friday’s magnitude 9.0 earthquake and subsequent tsunami.

The Tokyo Electric Power Company (Tepco), which runs the plant has been attempting to connect it to the main grid via a 1 km (0.6 mile) electricity cable.

The International Atomic Energy Agency (IAEA) said the cable had reached the site by 1730 local time (0830 GMT) on Thursday. Engineers planned to reconnect power to the reactor as soon as workers have finished spraying seawater over reactor 3. Tepco warned that the process of reconnecting power could take up to 15 hours.

A Tepco spokesman said the dumping of seawater by helicopters and water cannon appeared to have some success in preventing fuel rods from melting, although video footage had suggested most water had been missing the target buildings.

“When we poured water, we monitored steam rising from the facility. By pouring water, we believe the water turned down the heat. We believe that there was a certain effect,” spokesman said.

Another spokesman said on Thursday that observation from helicopters indicated that reactor 4 appeared to contain some water.

“We have not confirmed how much water was left inside but we have not had information that spent fuel rods are exposed,” he said.

Earlier, senior IAEA official, Andrew Graham described the situation at Fukushima as being “reasonably stable”, but it could deteriorate.

Japan has issued a clear zone around 20 km or 12 miles away from Fukushima and has urged people living within 30 km radius to remain indoors. Some countries have advised their nationals in Japan to stay up to 50 km away while others have advised their people to leave the country entirely.

Kyodo reports that the registered death toll affected by the twin natural disasters have risen to 5,692 but the true figure could be in the tens of thousands if included the unregistered ones. About 9,506 people reported missing and 380,000 people currently live in shelters, sleeping on floors of school gymnasiums.

Japan’s Kyodo news agency reported that search for victims had extended to a wider area as access had improved with clearance of debris.
