PR: American Nuclear Society welcomes Senate confirmation of Ted Garrish as the DOE’s nuclear energy secretary
Washington, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate's confirmation of Theodore “Ted” Garrish as Assistant Secretary for Nuclear Energy at the U.S. Department of Energy (DOE).
“On behalf of over 11,000 professionals in the fields of nuclear science and technology, the American Nuclear Society congratulates Mr. Garrish on being confirmed by the Senate to once again lead the DOE Office of Nuclear Energy,” said ANS President H.M. "Hash" Hashemian.

The solubility of nickel ferrite is measured at 423, 473, and 523 K in a pure or oxygenated water system, which is similar to boiling water reactor conditions‚ using a specially designed batch autoclave system. Thermodynamic analysis is performed by a procedure minimizing Gibbs free energy of the system at the final state. On the basis of both the analysis and the experimental results, it is shown that the dissolution mechanism of NiFe2O4 under the condition where no redox reaction takes place consists of both NiFe2O4 dissolution and Fe2O3 precipitation equilibria. The calculated value of the solubility at 423 K using literature values of the thermodynamic data agree with the experimental value, but at 473 and 523 K they deviate somewhat from the experimental ones. By fitting to the experimental results at these temperatures, the thermodynamic data of NiFe2O4 for 473 and 523 K are reanalyzed, and new values are proposed.
