Organic components of nuclear wastes and their potential for altering radionuclide distribution when released to soil

Description: Normal waste processing at the Hanford operations requires the use of many organic materials, chiefly in the form of complexing agents and diluents. These organic materials and their chemical and radiolytic degradation products, have potential for complexing fission products and transuranium elements, both in the waste streams and upon infiltration into soil, perhaps influencing future sorption or migration of the nuclides. Particular complexation characteristics of various nuclides which const… more

Depth distributions of low energy deuterium implantations in (110) tungsten: a theoretical model

Description: The depth distributions of 80 eV D/sup +/ implants in (110) W have recently been measured by field desorption microscopy. Prominent structure, consisting of seven major and several minor peaks, is observed in the measured distributions. This contrasts with conventional implantation theory which predicts two peaks, one for the channeled D/sup +/ and one for the nonchanneled D/sup +/. The observed structure is explained in the present report by a model which ascribes the various peaks to D/sup +/… more
