On 2/14/2019, Tepco announced they managed to contact the molten nuclear fuel on the bottom of the Primary Containment Vessel of Reactor 2.
The research was implemented on 2/13/2019. No data about the radiation level has been published.
According to Tepco, the specialized machine contacted the scattered fuel debris at 10 locations of the bottom of pedestal part.
The fuel debris was movable at 5 locations but media coverage is confusing at this moment.
However the exact locations of these 10 points are not defined even by Tepco. The researchable area is reportedly only 2% of the entire pedestal part.
