Design of a /sup 18/F production system at ORNL 86-inch cyclotron

Description: A target system for the production of /sup 18/F by proton bombardment of H/sub 2//sup 18/O was designed for the ORNL 86-inch cyclotron facility. The system consists of concentric titanium and aluminum cylinders. Oxygen-18-enriched H/sub 2/O circulates through the inner titanium cylinder and through an external heat exchanger with cooling water flowing in the annulus. Yields of 5.0 curies are expected for a 250-..mu..A proton beam current and 24-min irradiation time.

Interactions of radionuclides in water, particulates, and oysters in the discharge canal of a nuclear power plant. [Humboldt Bay reactor]

Description: This study was designed to provide data for dynamic modeling of radioactive pollutants in marine ecosystems adjacent to nuclear power plants. The data are relevant to the dynamics of radionuclide transfer among seawater, suspended particulates, sediments, and biota. Gamma-emitting radionuclides (/sup 54/Mn, /sup 60/Co, /sup 65/Zn, and /sup 137/Cs) were followed in the water and particulates, as well as in oysters introduced into the discharge canal of the boiling water reactor of the Humboldt B… more

Radiochemical studies for the nuclear chemical mining of copper. [Nuclear explosive fracturing]

Description: Experiments were performed to study the long-term reactions of radioactive materials that would be produced in the nuclear chemical mining of chalcopyrite copper ore. These reactions were carried out in autoclaves for up to eight months at 2.76 MPa of oxygen and 363 K. Dissolving rates of radioactive glass in copper-leaching product solutions were determined by the gamma-counting of solution aliquots. The glass decomposition rate was linear at approximately 1 x 10/sup -10/ kg/s.m/sup 2/. A radi… more

Tilted cranking classification of multibandspectra

Description: The existence of TDHF-solutions rotating uniformly about a nonprincipal axis of the deformed axial potential is demonstrated. The solutions represent {Delta}I=l bands. Selfconsistency and symmetry are discussed. The transformation of experimental spectra to the rotating frame of reference is introduced. Excitation spectra at high spin are calculated and found to agree well with recent data on {sup 163}Er and {sup 174}Hf.
