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
