Some of the relevant German organisations discarded dangerous waste at a construction site and then shredded the paperwork. That happened due to organisational traits, nothing to do with nuclear physics, but if my concern is that organisations with those organisational traits shouldn't be doing things with potential catastrophic effects, then you can't just answer with physics. Shredding paperwork is real, and my concern about is a concern to answer, not to ignore. If you ignore it, blame yourself for ignorance, not me for refusing to listen to "new information that addresses my concern".
This is similar to the Challenger space shuttle. NASA had organisational traits that led to powerpoint slides with seven different font sizes, and "the shuttle might burn" was in the smallest font size. The shuttle eventually did, and partly because organisation's culture was one to suppress risks using the smallest of seven font sizes. TEPCO did similar things at Fukushima — there was more emphasis on how to document that all requirements had been fulfilled than on maintenance. Sometimes that led to low costs and discrepancy between documentation and reality.
