Work is about to begin on the installation of a cover over Fukushima Daiichi unit 4 prior to the removal of fuel from the reactor building, Tepco has announced. A cover has already been built over the remains of unit 1 to prevent potential emissions of radioactive material, and similar covers are due to be built over units 3 and 4. Preparatory work has been under way since late March and work will begin on the cover for unit 4 on 17 April, the company has announced.

The design of the 51m tall structure, to be covered by steel panels, will be completed by the end of June and construction will start this fall.
In preparation for the construction the remaining parts of the outer shell, pillars and roof of the 5th floor on the north side of Unit 4 needs to be removed, and this work will be completed by the end of June.
The crane to lift the fuel from Unit 4 is expected to be manufactured in the third quarter of 2012.
