Tokyo Electric Power Company, or TEPCO, is rushing to put a makeshift roof over a turbine building at the Fukushima Daiichi nuclear power plant as typhoon
Ma-on approaches Japan.
TEPCO released a new photo on Sunday showing its preparation work.
The metal roof will cover the turbine building of reactor Number 3. The hole in its roof was caused by a hydrogen blast in March.
The new roof is 5-meters long and 16-meters wide. It is designed to cover up the hole to prevent an increase of radioactive water in the building.
TEPCO says the roof is scheduled to be installed with a crane on Monday.
Fearing high waves, a hose was temporarily disconnected from the “megafloat” barge, which contains relatively low-level radioactive water.
But no measures have been taken to prevent rainwater from entering reactor buildings 1, 3, and 4. The structures were damaged by hydrogen blasts.
However TEPCO says it does not expect any drastic increase of the water level in those 3 buildings.
At the Fukushima Daini nuclear power plant the doorway of reactor number 1 was also repaired to prevent rainwater leaks.
