What problems were those?
Yankee problems? Cooling tower supply lines leaking for many years in an underground tunnel contaminating soil and the Connecticut river with Cesium and Strontium. Cooling lines on a 40 year old wooden structure that collapsed causing soil and river contamination. Lost and unaccounted for nuclear material in the spent fuel pool. Unauthorized material in the spent fuel pool, on and on. All this is documented.
The undocumented stories come from friends that worked there (I live in the warning zone). Use of staff from outside areas of the plant for “hot” work during shutdowns to keep operational staff from over exposure. Known contaminated PPE not taken out of service (just marked by workers and told don’t use that one). Lots of cool stuff like that.
