3.2.3 Inside the Daiichi power plant
This video shows the inspection of the Daiichi plant in May 2011, two months after the initial crisis.
The damage done to the plant by the explosions is apparent as is the continuing presence of seawater.
The inspectors are an international group of scientists. They are there to work out what happened and why; to fully understand the physics so that appropriate precautions can be taken within the nuclear industry.
During the first few weeks, many were frustrated at the piecemeal nature of the information coming out of Daiichi so this visit was also an opportunity to increase transparency of information.
Initially, the main battle was with the reactors themselves. As time went on the overriding issue became the continuing effort to limit the radioactive contamination of the area and to try to contain the Daiichi site.
