Water release from heated concretes

Description: Water release from three concretes as a function of temperature has been determined experimentally. Limestone concrete releases more water at a moderate temperature than do magnetite or basalt concretes. The amount of water in the concretes is 6.2%, 6.3%, and 5% by weight for limestone, basalt and magnitite concretes, respectively. All of the concretes show three distinct weight losses as a function of temperature. By 450K, 52 to 75 percent of the water is lost - all of the water is lost by 750… more

Waste/Rock Interactions Technology Program: the status of radionuclide sorption-desorption studies performed by the WRIT program

Description: The most credible means for radionuclides disposed as solid wastes in deep-geologic repositories to reach the biosphere is through dissolution of the solid waste and subsequent radionuclide transport by circulating ground water. Thus safety assessment activities must consider the physicochemical interactions between radionculides present in ground water with package components, rocks and sediments since these processes can significantly delay or constrain the mass transport of radionuclides in … more

Underground nuclear explosions at Astrakhan, USSR

Description: The three underground nuclear explosions recorded in 1980 and 1981 by Hagfors Observatory in Sweden are in the vicinity of Astrakhan on the Caspian Sea. They are believed to be associated with the development of a gas condensate field discovered in 1973. The gas producing horizons are in limestones at 4000 m depth. They are overlain by bedded, Kungarian salts. Salt domes are recognized in the area. Plans to develop the field are contained in the 11th Five Year Plan (1981-82). The USSR has solic… more

Scaled-up testing of alternative trapping agents for radioactive constituents in plant vent streams

Description: Radioactive discharges from the Portsmouth Gaseous Diffusion Plant vent streams are in compliance with present standards specifying radiation limits. Regulatory trends have become increasingly restrictive on the maximum permissible dose to a member of the public. This could mean more stringent controls for radioactive emissions in the future. Fixed bed activated alumina (Al/sub 2/O/sub 3/) trapping is currently the principal method of limiting plant vent stream emissions of technetium and urani… more
