Early success at Fukushima Dai-ichi


Unit 4 Fuel Loaded In Cask At Fukushima Daiichi
18 November, 2013


TEPCO has released photos of the first fuel successfully removed from the fuel racks at unit 4. NHK reports the removal of some of the unused fuel from the pool to the transfer cask. TEPCO estimates it may take a week to load the first cask of 22 fuel assemblies before they can remove it from the pool.

From TEPCO’s press release distributed via email:

“Tokyo, Japan, Nov. 18, 2013-TEPCO announced today that they have started the fuel removal from the Unit 4 spent fuel pool at Fukushima Daiichi NPS. The start of fuel removal from the pool marks an important milestone in the decommissioning work at the site. The extraction work started at 3:18PM and the first fuel completed its extraction from the fuel rack to the cask placed inside the pool at 3:57PM as planned, following thorough safety preparations with the cooperation of many partner companies and individual workers.


Preparation work started from 9:50AM. The cask to carry the fuel was placed into the spent fuel pool and reached the bottom of the pool at 12:30PM. 22 unused fuels will be moved to the cask a task which is planned to be completed by November 19. After being filled with fuel, the cask will be closed with a lid, and following decontamination, will be taken down to ground level and transported to the common spent fuel pool on a trailer. It is planned to take approximately one week from placing the fuel into the cask at the spent fuel pool to storing it in the common pool. The entire removal of all fuel inside the Unit 4 spent fuel pool is planned to take until the end of 2014.”

TEPCO also released a follow up press release at the end of the day via email:
“Fukushima, Japan, Nov. 18, 2013-TEPCO announced today that they have completed the first day work for fuel removal from the Unit 4 spent fuel pool at Fukushima Daiichi NPS. Four fuel assemblies were loaded into the cask, and all the work for the day completed at 6:45PM.”

    TEPCO will probably do a competent job of removing the undamaged assemblies. It's the ones that are bent at a funny angle that might be a problem. some of them are leaking too, and their removal will be harder.
