This video shows various measures against dust dispersion during the dismantling work of cover panels over Unit 1 reactor building. At Unit 1, rubble from the damaged building caused by the hydrogen explosion is still scattered and needs to be removed. Cover panels were placed over the rubble to prevent the dispersion of radioactive materials, but dismantling of the panels started in July 2015 to remove the rubble. Wall pannels will be taken down around September 2016.
