It’s high alert time for Fukushima nuclear plant, and the whole nuclear industry

Japan and nuclear power High alert The riskiest part yet of the Fukushima clean-up is soon to begin The Economist, Nov 16th 2013 | FUKUSHIMA AMONG the twisted metal and random debris that litter much of the Fukushima Dai-ichi nuclear power plant, the fourth reactor looks in relatively good condition. A new structure covers the damage from a hydrogen explosion that blew its roof off days after a massive earthquake and tsunami hit the plant in March 2011. But the building is still unstable, and its spent-fuel storage pool highly dangerous. This month Tokyo Electric Power (TEPCO) will start plucking out over 1,500 radioactive rods from the pool in order to store them more safely. Over the pool a crane waits to start the procedure, and a yellow radiation alarm stands at the ready. Experts call the operation the riskiest stage of the plant’s clean-up so far.

Removing spent fuel is a routine task at all nuclear facilities, says Akira Ono, the plant’s manager. Engineers will have to take out each fuel assembly one by one without mishap, and overcome the risks of fire, earthquake and the pool boiling dry. The fuel rods can ignite if they lose coolant, or explode if they collide.

The rods are being moved just when trust in the utility that owns Fukushima Dai-ichi is at a low point. …… some are calling for the removal of spent-fuel rods from reactor four to be closely monitored by foreign experts. Even the pro-nuclear ruling Liberal Democratic Party (LDP) wants to take TEPCO in its current form out of the decommissioning process, which will take 40 or more years. A new entity, including the utility’s staff but separate from its commercial side, would take charge……..Junichiro Koizumi, a popular LDP former prime minister, has stepped in, calling for an immediate end to nuclear power. After he broadcast his views at a press conference, a poll showed that three-fifths of those who were surveyed backed his plan.

Mr Koizumi still knows how to rouse the public, says Jeff Kingston of Temple University in Tokyo, but there is little chance that Mr Abe’s commitment to nuclear power will change. His government’s links to the “nuclear village” are too strong. Big business is clamouring for the power stations to restart. Mr Koizumi’s style is certainly more orthodox than Taro Yamamoto’s. At a garden party, the new member of parliament dared to hand a letter to the emperor, Akihito, about the impact of the Fukushima catastrophe. Such direct contact with a near-divine was considered an outrage by everybody in the establishment (except Akihito, who carried on chatting with him). Japan’s nuclear-energy drama is far from over. http://www.economist.com/news/asia/21589912-riskiest-part-yet-fukushima-clean-up-soon-begin-high-alert
