I think that it critical to have independent auditing/regulation of all energy facilities, including those that are not as clean as nuclear facilities.

Believe it or not, the foresic analysis of Chernobyl disaster showed that there were regulations in place and a regulatory authority.   But they were really not independent and both reported to the committee responsible for meeting the goals of the 5 year plan.

The test that lead to the Chernobyl failure was supposed to take place before the reactor ever operated, but it was skipped to meet the political goals of the 5 year plan.

Moreover the test did not obey specific protocols included in it, and the operators, who were not nuclear engineers but electrical engineers, conducted the test on an ad hoc basis.

I think that unannounced auditing by both independent national and independent international authorities should become de riguer.

I would extend such ruling to the coal industry and the gas industry as well, which will help to cause them to be shut more quickly.
