![]() Since 1968, no personnel have exceeded 5 rem per year, which was the Program’s self-imposed limit until it became the federal limit in 1994. No civilian or military personnel in the Naval Nuclear Propulsion Program have ever exceeded the federal lifetime radiation exposure limit or the federal annual limit in effect at the time. In carrying out this policy, the Program has consistently maintained personnel radiation exposure standards more stringent than those in the civilian nuclear power industry or in other government nuclear programs. Naval Nuclear Propulsion Program is to reduce personnel exposure to ionizing radiation associated with naval nuclear propulsion plants to the lowest level reasonably achievable. For example, the first submarine core endurance was about 62,000 miles today, submarine and aircraft carrier cores have an endurance of over 1 million miles. ![]() The combined efforts of the Program's research, development, and support labs have led to tremendous advances in naval reactor technology.The data derived from these examinations are used to develop new technology and to improve the cost-effectiveness of existing designs. The government-owned/contractor-operated Naval Reactors Facility, located within the Idaho National Laboratory, examines naval spent nuclear fuel and irradiated test specimens. ![]() Both Bettis and Knoll offer postgraduate research opportunities through the Naval Nuclear Propulsion Fellowship Program. Knolls Atomic Power Laboratory operates prototype nuclear propulsion plants in New York for the operational testing of new designs and promising new technologies under typical operating conditions before introducing them into the fleet. With combined staffs of over 6,100 engineers, scientists, technicians, and support personnel, their mission is to develop the most advanced naval nuclear propulsion technology and to provide technical support for the continued safe, reliable operation of all existing naval reactors. The government-owned/contractor-operated Bettis and Knolls Atomic Power Laboratories are research and engineering facilities devoted solely to naval nuclear propulsion work.Program responsibilities are delineated in Presidential Executive Order 12344 of February 1, 1982, and prescribed by Public Laws 98-525 of Octo(), and 106-65 of Octo(). ![]() The Program has cradle-to-grave responsibility for all naval nuclear propulsion matters. The Naval Nuclear Propulsion Program comprises the military and civilian personnel who design, build, operate, maintain, and manage the nuclear-powered ships and the many facilities that support the U.S. ![]()
