Fuel removal at Fukushima reactor again faces delay

dec-23-2016

Steel frames are transported at the Fukushima No. 1 nuclear power plant on Dec. 20 to prepare for work to retrieve spent nuclear fuel from the storage pool of the damaged No. 3 reactor building.

Work to retrieve spent nuclear fuel in the No. 3 reactor building storage pool of the crippled Fukushima No. 1 nuclear power plant will again be postponed due to a delay in clearing radioactive debris at the site.

TEPCO planned to begin removing 566 spent nuclear fuel assemblies in the storage pool in January 2018. However, the government and the plant operator, Tokyo Electric Power Co., decided on the postponement, sources said on Dec. 22. They will decide on a new timetable in a few weeks.

The work was initially scheduled for fiscal 2015, but had been pushed back because of high radiation readings in and around the No. 3 reactor building. The building was heavily damaged by a hydrogen explosion in the days following the disaster, triggered by the 2011 Great East Japan Earthquake and tsunami.

TEPCO had attempted to lower radiation levels by clearing the radioactive debris remaining at the site.

But the clearing work took longer than expected due to contamination being more widespread than previously thought, forcing TEPCO and the government to again put off the retrieval.

Radiation levels have now dropped as almost all of wreckage at the site has been cleared, TEPCO said. The government and TEPCO have said fuel retrieval at the No. 1 and No. 2 reactor buildings will start in fiscal 2020 or later.

Fuel Removal from Fukushima Reactor 3 Likely to Be Put Off Again

Tokyo, Nov. 18 (Jiji Press)–Tokyo Electric Power Co. Holdings Inc. <9501> is expected to face a further delay in the start of work to remove fuel from the storage pool at the No. 3 reactor of its disaster-stricken Fukushima No. 1 nuclear power station, it was learned Friday.
It now appears difficult to begin the work in January 2018, as currently targeted by the company, the sources said. The expected postponement is due to a delay in preparations necessary for the removal work.
All six reactors at the power station in Fukushima Prefecture, northeastern Japan, are set to be decommissioned, after the plant was knocked out by the March 2011 earthquake and tsunami. Three of the six reactors suffered core meltdowns in the accident.
The fuel removal from the No. 3 reactor pool was initially planned to begin during April-September 2015.
The No. 3 reactor building was heavily damaged by a hydrogen explosion soon after the March 11 disaster. As part of the preparations, TEPCO plans to install a cover and relevant equipment at the reactor.
