Naval Reactors' Department of Energy Facilities http://navalreactorshistorydb.info:8080/xtf/data/pdf/060/060.pdf This report focuses on radiation exposure at facilities managed by the Department of Energy's Office of Naval Reactors. As noted in the report, "the policy of the Naval Reactors Program is to reduce exposure to personnel from ionizing radiation associated with Naval Reactors' Department of Energy facilities to a level as low as reasonably achievable" (5). Naval Reacors "operates two Department of Energy laboratories; one Department of Energy site with two operating and one inactive prototype naval nuclear propulsion plants; one Department of Energy site that operates the Expended Core Facility (for dispositioning of naval fuel and examination of irradiated test specimens) and has three inactive prototype nuclear propulsion plants; and nuclear component engineering and procurement organizations" (1). These facilities provide support for the United States Navy's 82 combatant vessels (submarines and aircraft carriers). For the prototype plants, the major source of radiation expoure is maintenance inside th... http://navalreactorshistorydb.info:8080/xtf/data/pdf/060/060.pdf Fri, 01 Jan 2010 12:00:00 GMT Occupational radiation exposure from U.S. naval nuclear plants and their support facilities. http://navalreactorshistorydb.info:8080/xtf/data/pdf/075/075.pdf As noted in the summary, this report describes "radiation exposures to Navy and civilian personnel monitored for radiation associated with U.S. naval nuclear propulsion plants" (1). Most of the exposure comes "from inspection, maintenance, and repair inside the reactor compartment [following reactor shutdown]. The major source of this radiation is cobalt-60 deposited inside the piping systems" (5). Additionally, "the radiation exposures in this report are almost entirely from gamma radiation," given the low level of neutron radiation following shutdown (9). The report describes the high priority placed by the Naval Reactors organization on reducing exposure, noting that "shield design criteria establishing radiation levels in various parts of each nuclear-powered ship are personally approved by the Director, Naval Nuclear Propulsion" (5). It provides an in-depth summary of personnel dosimetry used in the Naval Nuclear Propulsion Program throughout its history. The move from calcium fluoride thermolumines... http://navalreactorshistorydb.info:8080/xtf/data/pdf/075/075.pdf Sat, 01 Jan 2011 12:00:00 GMT
