there are no coincidences
Up until this fire, I thought that Ymani had the inside edge on the fires and derailments.
No way does activists/agitators get into Y-12 unknown to start this.
A fire in the U238 processing area is SIGNIFICANT and exceedingly rare (discounting the occasional office-dust-bin fires when smoking at your desk was allowed).
You could likely count the number of these fires on one hand throughout our Nuclear history (less than 90 years).
