Brief Fukushima Daiichi update- Sunday 5/22

As reported on this blog on April 23, TEPCO has (again) noted the discovery of radioactive debris on the Fukushima Daiichi site which is emitting between 90 R/hr and 100 R/hr. This debris is near the No. 3 plant reactor building, reportedly, and as noted before is the highest dose rate found on site yet.. that is, outside of the plant buildings, anyway.

TEPCO has reduced the feed rate to No. 3 reactor again. According to the TEPCO press release, flow rate through the feed line has remained constant today at 12 cubic meters per hour, but feed flow through the firefighting connection has been reduced in steps. At 5:39 AM this was reduced from 9 cubic meters per hour to 8; at 8:43 AM to 7; and at 11:54 AM finally to 6 cubic meters per hour. Thus, as of now the total feed rate to No. 3 is 18 cubic meters per hour. No. 1 plant, for comparison, is at 6 cubic meters / hr while No. 2 plant is at 7 cubic meters / hr.

The "mega-float" barge is now at Fukushima Daiichi.
