Page 374 - Releases at Sea Radioactive liquids incidental to the operation of the nuclear propulsion plants are released at sea under strict controls. These ocean releases are consistent with recommendations the Council on Environmental Quality made in 1970 to the President in reference 35, and consistent with the Marine Protection, Research and Sanctuaries Act, reference 36.
Page 373 - ... million curies. Because of this naturally occurring tritium, much larger releases of tritium than are conceivable from Naval nuclear reactors would be required to make a measurable change in the background tritium concentration. The total amount of tritium...
Page 112 - LSD 41 (Cargo Variant). This ship will transport and launch amphibious craft and vehicles with their crews and embarked personnel in amphibious assault operations. It will also provide limited docking and repair services for conventional landing craft and LCAC. The ship will differ from the original LSD 41 in that It will have additional cargo capacity and two fewer LCAC.
Page 317 - Mathematics at the National Institute of Standards and Technology, formerly the National Bureau of Standards.
Page 369 - Releases from the shipboard reactors occur primarily when reactor coolant water expands as a result of being heated to operating temperature; this coolant passes through a purification system ion exchange resin bed prior to being transferred from the ship. The principal source of radioactivity in liquid effluents is trace amounts of corrosion and wear products from reactor plant metal surfaces in contact with reactor cooling water. Radionuclides with half-lives greater than one day in these corrosion...
Page 385 - Agency has analyzed samples from harbors to identify radionuclides present in sediment. These analyses showed cobalt 60 was the predominant radionuclide added to sediment from Naval nuclear reactor operations. Therefore, Navy monitoring...
Page 369 - Protection Agency in 1970), US Nuclear Regulatory Commission, National Council on Radiation Protection and Measurements, International Commission on Radiological Protection, International Atomic Energy Agency, and National Academy of Sciences — National Research Council (references 24 through 32). Keeping releases small minimizes the radioactivity available to build up in the environment or to concentrate in marine life.
Page 377 - SOLID RADIOACTIVE WASTE DISPOSAL During maintenance and overhaul operations, solid lowlevel radioactive wastes consisting of contaminated rags, plastic bags, paper, filters, ion exchange resin and scrap materials are collected by nuclear-powered ships and their support facilities. These low level radioactive materials from nuclear-powered ships are required to be strictly controlled to prevent loss.
Page 374 - As a result, the radioactivity concentration guide for carbon 14 in its chemical form in air issued by the International Commission on Radiological Protection, the National Council on Radiation Protection and Measurements, the US Nuclear Regulatory Commission and by other standard-setting organizations is three thousand times higher than for cobalt 60.
Page 372 - Reactor coolant also contains short-lived radionuclides with half-lives of seconds to hours. Their highest concentrations in reactor coolant are from nitrogen 16 (7 second half-life) , nitrogen 13 (10 minute half-life), fluorine 18 (1.8 hour halflife), argon 41 (1.8 hour half-life) and manganese 56 (2.6 hour half-life).
