Feds, state agree on deadlines for treating Hanford’s tank waste
The U.S. Department of Energy, Washington State Department of Ecology, and U.S. Environmental Protection Agency have reached an agreement on revised plans for managing millions of gallons of radioactive and chemical liquid waste stored in 177 underground tanks at the Hanford Site near Richland, Wash.

A search was conducted for neutrons, protons, tritons, 3He ions, gamma rays, and ion-induced X rays from deuterium-deuterium (D-D) fusion in cast (36-g), annealed (4-g), and cold-rolled (16-g) palladium specimens and a palladium hydrogen thermal valve (11 g) electrochemically charged with deuterium. The palladium cathodes were charged in an electrolytic cell [0.1 M LiOD (99.8% deuterium), platinum anode] at a current density of 25 mA/cm2 from 20 to 140 h. One unique aspect of the experiment was the radiation detection system, consisting of a CR-39 track-etch detector, bare for proton detection (sensitivity limit 4.8 × 10−2 fusion/s), combined with a polyethylene fast neutron radiator (0.95 fusion/s), a boron thermal neutron radiator (26 fusion/s), a BD-100 bubble damage polymer detector (5.2 fusion/s), an array of six 3He proportional counters (126 fusion/s), a CaF2 thermoluminescent dosimeter (11.4 fusion/s), and a germanium semiconductor spectrometer (17 fusion/s). The D-D fusion rate in cast, annealed, and cold-rolled palladium is <3 × 10−22, <7.8 × 10−21 and <1.2 × 10−21 (D-Dn) fusion/D-D pair·s−1, respectively. In the palladium hydrogen thermal valve, this value was <1.1 × 10−23 (D-Dp) fusion/D-D pair·s−1 and <2.3 × 10−22 (D-Dn) fusion/DD pair·s−1.
