New video footage of the storage pool inside the No. 4 reactor building of the crippled Fukushima No. 1 nuclear power plant showed that little had changed since observations made last May.
New video footage of the storage pool inside the No. 4 reactor building of the crippled Fukushima No. 1 nuclear power plant showed that little had changed since observations made last May.
The Feb. 9 video, released by Tokyo Electric Power Co. a day later, showed concrete and other debris from a hydrogen explosion in March strewn about the spent fuel pool.
The pool was exposed to the atmosphere after the hydrogen explosion tore through the structure on March 15. The reactor had been shut down before the March 11 Great East Japan Earthquake struck.
The pool was clearly visible up to 5 meters deep in the video footage, but other parts were unclear, TEPCO said.
No change in the shape of the spent fuel assemblies was observed.
TEPCO said it plans to purify the water in the pool and retrieve wreckage with underwater cleaners.
