Separation of fission produced 106Ru from simulated high level nuclear wastes for production of brachytherapy sources

An effective and simple process for the isolation of 106Ru from high-level liquid wastes was developed. Radioactive ruthenium was oxidized by H5IO6 in HNO3 solution and was extracted to CCl4 phase in the form of RuO4. In order to obtain ruthenium in the suitable form for production of brachytherapy sources, RuO4 in organic phase was reduced and re-extracted to aqueous phase. The efficiency of e...

The Management of High-Level Radioactive Wastes

The terms, low-level, mediumor intermediate-level and high-level radioactive wastes are being universally used, implying different concentrations of radionuclides or radioactivity in the waste. These terms originated in the 1950's for operational purposes and generally indicated how the waste was being handled or treated and what was being done with it under the local operating conditions at a ...

Project Title : Studies Related to Chemical Mechanisms of Gas Formation in Hanford High - Level Nuclear Wastes

Determination of the nuclear level density at high excitation energy.

Evaporation simulations are presented to illustrate the problems associated with the determination of the nuclear level density constant at high excitation energy from evaporation spectra. The methods of using either the total (whole chain) spectra or the difference (from two different initial excitation energies) spectra are discussed. Data from the study of the reaction 701 MeV 'Si+ ' Mo are ...
