The armament of any aircraft carriers exceeding 27,000 tons (27,432 metric tons...
Page 63 - A capital ship, in the case of ships hereafter built, is defined as a vessel of war, not an aircraft carrier, whose displacement exceeds 10,000 tons (10,160 metric tons) standard displacement, or which carries a gun with a calibre exceeding 8 inches...
Page 160 - Tritium Small amounts of tritium are formed in reactor coolant systems as a result of neutron interaction with the approximately 0.015 percent of naturally occurring deuterium present in water, and other nuclear reactions. Although tritium has a 12 year half-life, the radiation produced is of such low energy that the radioactivity concentration guide issued by the International Commission on Radiological Protection, the National Council on Radiation Protection and Measurements, the US Nuclear Regulatory...
Page 158 - Keeping releases small minimizes the radioactivity available to build up in the environment or to concentrate in marine life. To implement this policy of minimizing releases, the Navy has issued standard instructions defining the radioactive waste disposal limits and procedures to be used by US Naval nuclear-powered ships and their support facilities.
Page 167 - Cobalt 60 is not detectable above background levels in general harbor bottom areas away from these piers. Maximum total radioactivity observed in a US harbor of less than 0.l curie of cobalt 60 is small compared to the naturally occurring radioactivity.
Page 137 - Similarly alpha emitters such as uranium andplutonium are retained within the fuel elements and are not accessible to personnel operating or maintaining a Naval nuclear propulsion plant. Because of the high Integrity of reactor fuel and because soluble boron Is not used...
Page 160 - However, trace quantities of naturally occurring uranium impurities in reactor structural materials release small amounts of fission products to reactor coolant. The concentrations of fission products and the volumes of reactor coolant released are so low, however, that the total radioactivity attributed to long-lived fission product radionuclides, strontium 90 and cesium 137, in releases from US Naval nuclear-powered ships and their support facilities has been less than 0.001 curie per year for...
Page 169 - EPA evaluation in reference 3f shows that the cobalt 60 from Naval nuclear propulsion plants is in the form of metallic corrosion product particles which do not appear to be concentrated in the food chain. Because of the nature of the radioactivity and...
