From remediation to renaissance: Our nuclear future begins with cleanup
ANS Executive Director/CEO Craig Piercy’s reflection on the 80th anniversary of the Trinity Test (Nuclear Newswire, July 16) was a thoughtful and fitting remembrance of the achievements and legacy of the World War II generation of nuclear pioneers. We also see legacy environmental cleanup as a vital next step as our industry launches what Secretary of Energy Chris Wright has defined as “Manhattan Project 2.0.”
