Nuclear Incident Response and Assistance Operations for Domestic Transportation of U.S. Nuclear Weapons and Their Special Nuclear Material This major revision, dated 24 March 2022— • Changes title from “Nuclear Accident or Incident Response and Assistance Operations” to “Nuclear Incident Response and Assistance Operations for Domestic Transportation of U.S. Nuclear Weapons and Their Special Nuclear Material.” This is an accurate title to what this publication is about (para 1–1). • Added approach all U.S. nuclear weapon and radiological material incidents as if they could be the result of a hostile act until determined otherwise and consider a U.S. nuclear weapon to be an improvised nuclear device at the moment of loss of control. Department of Justice/Federal Bureau of Investigation will determine that the incident does not have hostile intent (paras 1–5f and 2–7b ). • Added Domestic U.S. nuclear weapon accidents and incidents referred to collectively in this publication as “incidents” ( para 2–2h ). • Replaces “Nuclear Accident or Incident Response and Assistance Operations” with “Nuclear Incident Response and Assistance Operations” (throughout). • Replaces “Nuclear Accident or Incident” with “Nuclear Incident” (throughout).
