TEPCO, according to NHK, has revised its fuel damage estimates for the three reactor plants at Fukushima Daiichi with installed cores.
TEPCO now says fuel damage percentage at No. 1 plant is 55%, not the 70% it had first thought. This is a lot closer to the NRC estimate in the mid-60's.
No. 2 and No. 3 plant have now apparently been rounded up to 35% and 30% respectively.
These revisions have been made, in the case of the first plant, because TEPCO hasn't found the rad levels it would expect if there were as much as 70% of the fuel damaged in the reactor core. In the other two cases, TEPCO seems to have admitted having erred in rounding initially so it gave the other two plants the extra five percent each.
The triggering for this re-estimation seems to have been a prodding from NISA, who felt that the estimate for No. 1 plant was incorrect based on reported rad levels, according to JAIF.
