Radioactive zinc ( sup 65 Zn), zinc, cadmium, and mercury in the Pacific Hake, Merluccius productus (Ayres), off the West Coast of the United States

Description: The Pacific Hake, Merluccius productus (Ayers) was used to monitor the waters off Puget Sound and the West Coast of the US for zinc(Zn), cadmium(Cd), mercury(Hg) and {sup 65}Zn. The Columbia River is not the source of Zn, Cd or Hg contamination, but is the source of {sup 65}Zn, with the concentration in the Hake reflecting the position of the Columbia River plume. Zn and Cd accumulation in the Hake were fit to the equation Y=B{sub 1}+B{sub 2}e{sup B}{sub 3}X where Y is the concentration of the … more

Mini-Brayton economic RTG study. Final report

Description: The objective of this study is to demonstrate the applicability of a radioisotope heated Mini-Brayton power system to the 1973 USAF/AEC requirements established for the SURVSATCOM Mission. The principal requiremenets of the power system, are: 400 We power level; maximum weight 205 lbs.; $1.2 to 2.0 million per unit cost; and 5y mission duration. A radioisotope heat source that meets the ACE Nuclear Safety Criteria is presented. The major aspects of the Reference Design MB-ERTG are summarized. T… more

CHARMED PHYSICS AT THE TAGGED PHOTON LAB

Description: The recent discoveries of heavy narrow resonances at masses of 3.1 and 3.7 Gev came at the same time as the successful testing by our group of the electron beam in the Fermilab Tagged Photon Facility. The timing is perfect, as this facility with its clean environment and relatively high photon fluxes and energies will be the ideal location for several important experiments suggested by the new results. We outline below the new significance of our experiment to measure the photon total cross sec… more

Preliminary safety analysis of the B-C Cribs Controlled Area. [Hanford Reservation]

Description: Approximately 2,000 acres of land in the center of the Hanford Reservation is contaminated with an estimated 14 Ci of /sup 137/Cs and 81 Ci of /sup 90/Sr associated with animal wastes. Approximately half of this activity is located on (or within) 2.5 centimeters of the ground surface. The source of the contamination was the B-C Cribs and trenches which were used as liquid radioactive waste disposal sites during the 1950's. The mechanism for movement of radionuclides from the disposal site to th… more

Emitted and decayed values of radionuclides in gaseous wastes discharged to the atmosphere from the separation facilities through calendar year 1972

Description: Gaseous wastes from the chemical separations processing of spent reactor fuel elements and product finishing operations have been discharged to the atmosphere since 1944. Data on plutonium, beta, iodine, and uranium emissions for the twenty-nine years are provided. The known radioactivity in gaseous wastes and estimated radioactivity in gaseous waste where prime data were not available are presented. Emission data are not included on gaseous wastes emitted from 200 Area facilities which are now… more

Analysis of Environmental Samples From the Mound Lab. Area. Progress Report

Description: All of the available analytical results from the 8 sediment cores and 16 water samples obtained from water bodies in the vicinity of Mound Laboratory during July 1974, are reported here. These include /sup 238/Pu in both sediment and water, /sup 241/Am in sediment and /sup 3/H in water. The quality of these analyses was found to be acceptable with the exception of an approximately 30% bias in the accuracy of the /sup 238/Pu data.

Environmental and technological implications of a theta-pinch fusion power plant

Description: The environmental effects of this conceptual design were evaluated and found to be little different from other electrical power plants in most regards. Exceptions include a very small release of tritium, a low-hazard isotope, and relatively large amounts of radioactive material which must be either stored on site for eventual reprocessing or permanently discarded. These radioactive materials are nonvolatile and should not pose a difficult disposal problem, although some of the material may rema… more

Direct Conversion of Neutron Energy and Other Advantages of a Large Yield Per Pulse, Inertial-Confinement Fusion Reactor

Description: Aspects of an inertial-confinement, fusion reactor that uses an energy release {approx gt}10{sup 11} joules are discussed. The large energy release makes possible direct conversion of the fusion neutrons' energy after nuclear heating of an evaporated blanket to the plasma state. Surface damage by charged particles is avoided and structural damage by neutrons is alleviated. Complex fuel assemblies and other expandable parts may be used as a result of the high monetary value of the energy release. more

Leaching of radioactive nuclides from cement grouts. [Method for measuring rate of leaching of Cs-137 from cement grouts]

Description: A method for measuring the rate of leaching of /sup 137/Cs from cement grouts was investigated as an alternate to the International Atomic Energy Agency (IAEA) method which requires long experimental times. The effects of curing time (10, 20, and 30 days) and the type of leachant (tap and saline water) on the amount of /sup 137/Cs leached were studied. Mathematical models for mass transport phenomena for both finite cylindrical geometry and a semi-infinite medium were developed to analyze the d… more

Leaching of radioactive nuclides from cement grouts. Part II

Description: The determination of the leaching rate of radioactive /sup 137/Cs from a cement grout should the grout be contacted by water is necessary for environmental protection. The effect of the leachant turnover rate on /sup 137/Cs leaching rates was evaluated with batch and continuous (modified Soxhlet extractor) modes of experimentation. Three additives (Grundite, potter's clay, and Conasauga shale) were compared in terms of capability of radioactive isotope retention, while two leachants (tap and di… more

Lethal and mutagenic effects in microorganisms grown in $sup 3$H$sub 2$O. Final report

Description: Results are summarized from studies of lethal and mutagenic effects in microorganisms grown in tritiated water. It was concluded that the effects of radiation alone are sufficient to explain the biological effects observed. Studies on the effect of tritium decays accumulated during growth of organisms in the presence of tritiated nucleic acid precursors showed that the mutation rates per decay for continuous growth and for storage conditions were identical and that tritium-labeled adenine and c… more
