Tepco started dismantling the cover of Reactor 1 on 10/22/2014.

The cover was installed in October of 2011 in order to stop radioactive material spreading supposedly.

To removed the molten fuel somewhere around the reactor, they need to remove 392 fuel assemblies in Spent Fuel Pool of Reactor 1 in advance, which is planned in 2017. However the spent fuel assemblies cannot be removed with the cover.

Currently they are to open approx. 50 holes on the top of cover to spray scattering inhibitor inside. However the main body of the cover cannot be removed until the end of February because there is no space around the reactor building due to the “frozen water wall” construction on-going.

The preceding “frozen water wall” failed. If this on-going “frozen water wall” construction is also delayed or failed, Reactor 1 fuel removal is going to be delayed as well.
