RE: 60th criticality accident
The handouts I received at a criticality safety course at Los Alamos
include 21 process line criticality accidents and approximately 30 critical
assembly / reactor experiment accidents. These include international
accidents (including the former Soviet Union). These numbers would seem to
roughly agree with the 60 accidents being reported in the news.
