TEPCO To Do More Inspections In Unit 1 Containment

Kyodo News is reporting TEPCO will do a series of inspections this week at unit 1 to look inside containment and take samples. They estimate photos should be out Wednesday. TEPCO has released a document explaining what work will be done but the document is only in Japanese. The work will include more visual inspection with a camera, radiation readings of water and air inside containment and testing of the stagnant water inside containment.

As more information comes out we will release reports and analysis.
