The verdict

Duane Arnold runs at 25% of its industry's injury rate - far safer than the typical Electric power generation, nuclear workplace, earning a grade A.

Duane Arnold: 0.3 TCR = 25% of Electric power generation, nuclear BLS 1.2 · 3y Form 300A (see methodology below)

Duane Arnold safety composite

Duane Arnold scores strongest on dart rate (safer than 66% of same-industry peers) and weakest on total case rate (tcr) (safer than 31%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
