Unit 1 Containment Scope New Images & Video

TEPCO has released more information about the ongoing inspection of unit 1 this week. Water was found inside at about OP 9000, near the top of the torus downcomer pipes in the drywell.
Radiation readings were also taken and showed higher readings closer to where they went into containment and lower the closer they went towards the water in the bottom of the drywell. The readings ranged from 9.8 Sv/h to 4.7 Sv/h with the water surface reading about .5 Sv/h. Near the penetration opening inside containment was about 11.1 Sv/h
