For the better part of the last 6 months, workers have been preparing Fukushima Daiichi Unit 4 for the extraction of the spent fuel from the spent fuel pool of the destroyed reactor building.  They have removed the debris  from atop the reactor building, and worked on preparing the structure to be covered by a steel cover in order to remove the spent fuel assemblies from the pool.

On January 8th, workers completed the first stage of the work to erect a steel cover in order to extract fuel from the reactor building.  The base of the cover has been set, consisting of 6 pillars and 7 beams.

The finished structure will include 4 more levels to be constructed on top of the newly-finished foundation, and will extend over the existing Unit 4 reactor building.
