History & TriviaNEW Fewer Than 10 American Veterans Who Saw Hiroshima and Nagasaki Are Still Alive. Their Stories Are DiFewer than 10 American service members who entered Hiroshima and Nagasaki as occupation troops in 1945 remain alive. These aging veterans are the last direct witnesses to the immediate human and structural devastation caused by the first wartime use of atomic weapons. For decades, government secrecy orders prevented these personnel from discussing their radiation exposure and observations. Preserving their firsthand accounts provides valuable historical documentation regarding the long-term health effects of radiation on military personnel and the realities of nuclear warfare. American occupation troops witnessed Hiroshima and Nagasaki weeks after the atomic bombs. Fewer than 10 are believed to remain alive. Less than 10 American veterans who saw the Japanese cities after 1945 bombings are...

Nuclear NewsNEW U.S. nuclear agency OKs Diablo Canyon safety report. What to knowThe Nuclear Regulatory Commission accepted a Pacific Gas and Electric materials report indicating that Diablo Canyon Unit 1 is not subject to premature embrittlement. The evaluation follows recent testing of a surveillance capsule removed from the reactor vessel. While federal regulators approved a 20-year license extension, continued operation past 2030 still requires approval from the state legislature. The report was published after the NRC granted a 20-year license for the power plant. A recent test conducted by PG&E and its contractor shows that materials in Unit 1 at the Diablo Canyon nu...
Nuclear NewsNEW Incident pauses Palisades fuel loading; plant connected to switchyardOperator Holtec paused fuel loading at the Palisades nuclear plant after a previously used fuel assembly tilted inside the reactor vessel.
