Someone unqualified to access the safety of nuclear power plants declares them unsafe.
Did you bother to even skim the article? It was essentially entirely focused on human and organizational risk factors, the sort of thing that anthropologists do actually study, in US nuclear facilities and preferred methods of securing them.
If the concern is "will the roof resist a hardware-store-improv mortar attack?", sure you don't want an anthropologist on the job. If the concern is "so, will the guards notice, give a damn, and do something about it; or will I just have to walk past a token force optimized for cheating its way to passing grades during perfunctory audits at lowest possible cost?", that's an anthropological question. And the answer appears to tend toward the latter.
