The News That Matters about the Nuclear Industry

Once severely damaged Fukushima reactor building opened to media to showcase progress

Tepco’s representatives and METI’s officials have spent 15 minutes at the top floor of the reactor 3 building, 30 meters above the ground.
0,08mSv/per hour on the platform and 0,7mSv/per hour near the fuel pool with its 566 fuel assemblies supposed to be unloaded within 6 months. According to Tepco, workers cannot stay up there more than one hour or two per day….
The real content of that fuel pool is still mysterious, as no whole picture of that pool has ever been released.

The top level of the Fukushima No. 1 nuclear plant’s No. 3 reactor building was opened to the news media on Nov. 21.
The Ministry of Economy, Trade and Industry along with plant operator Tokyo Electric Power Co. (TEPCO) guided reporters to the reactor building’s top floor for a tour lasting about 15 minutes.
The building was badly damaged by a hydrogen explosion in the first days of the Fukushima nuclear crisis in March 2011. However, the debris has been cleared away, and radiation that had stood at 800 millisieverts per hour just after the reactor meltdowns was measured at 0.08 mSv/h on the 7-meter-high platform, on which fuel removal equipment and other devices have been installed, on Nov. 21. Closer to the fuel pool, the figure rose to 0.7 mSv/h. According to TEPCO, workers are limited to just one to two hours on the platform.

The top floor is about 30 meters from the ground. The spent fuel pool currently contains 566 fuel assemblies, and preparations are underway to start the removal process as early as mid-fiscal 2018, with equipment for the job already installed on the platform. A net currently covers the pool to prevent anything — or anyone — from falling in.
A semi-cylindrical cover is also being constructed to prevent radioactive materials from escaping when fuel removal operations begin.
