Anxiety, yes. Investigations, yes. Resignations, doubtful.
The response will be to rebuild, based on lessons learned.

Historical data was used in the reactor specifications.
Attention is focused on the reactors at Fukushima, but the other 50 centers are continuing operation.

Historical data was used in development of the Sendai urban centers; some 20,000 perished. Planning for rebuilding and relocation is underway, based on the 2011 experience.

Historical data was used in specifications for power grids and distribution systems, but some critical industries slowed or stopped, affecting production and jobs not only in Japan but in the U. S. and other countries with dependence on Japanese components. Re-location of power distribution lines from grid systems is underway.

Japan will rebuild, not recriminate and stagnate.

Nuclear power will continue to increase in importance, adding to the 50-odd reactors in use. The world's first full MOX plant was begun in 2008-09 in Aomori Prefecture, power generation expected in 2014. Kyushu Electric Power Co. began commercial operation Dec. 2009 after loading MOX from France. Shikoku Electric Power has loaded MOX at its Ikata 3 reactor (MOX also from France).
