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.
