#Fukushima I Nuke Plant Reactor 2 CV Endoscopy Is Done

(UPDATE: Photos inside the CV just released. See my post.)

=========================

At TEPCO's morning press conference on January 19, 2012, TEPCO's Matsumoto said that the endoscope was successfully inserted through the hole created on January 17 on the Reactor 2 Containment Vessel and the survey of the interior was done.

The work started at 9AM, and was done at 10:10AM. More details of the survey will be disclosed at the evening press conference at 6:00PM.

TEPCO thinks it is a partial meltdown in Reactor 2, and there is water up to 5 meter from the bottom of the Containment Vessel.

If you understand Japanese, you can view TEPCO's press conference live at TEPCO's site, here.

The morning press conference starts at 11:00AM JST, and the evening press conference starts at 6:00PM JST. (Even if you understand Japanese, you may find it incomprehensible.)

There's no information from TEPCO about the radiation level at the location that the workers had to work, other than the company expects the radiation exposure level for the workers would be 3 millisieverts.

10 groups of workers (if the Jan 19 crew is the same size as the Jan 17 crew), 1 hour 10 minutes job, and 3 millisieverts expected exposure would indicate one group would spend 7 minutes at the site to get 3 millisieverts radiation, and the radiation level at the site would be about 25.71 millisieverts/hour.

Not bad, compared to other reactors that has locations whose radiation is one to two digits higher.
