Decommissioning Successes:Hanford Site Reactors
of Hanford’s nine production reactors have been placed in interim,safe storage allowing radioactive decay before final demolition
more reactors will beplaced in safe storagein the next few years2
reactor was configured to allow public access for tours because it wasthe world’s first full-scale plutonium production reactor
