The IC operations between earthquake and tsunami on 3.11 are clearly denied by us at the Spring Meeting in 2016. TEPCO researcher made an attempt of MAAP analysis for the certification of IC operation, but the pattern of the figure is not credible.

We showed a numerical confirmation of PRV pressure and condenser heat removal.
