In 1973, the Japan Atomic Energy Industry Forum published a report entitled “A closed system for radioactivity”. The report pointed out the importance of R&D for P&T of long-lived nuclides as long-term efforts in developing a complete system for radioactive waste management. JAERI started the development of partitioning process for high-level liquid waste and the design study of transmutation s...

membrane assisted liquid extraction(male) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. the present contribution outlines the classification of membrane assisted ...

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 ...

The liability regime governing geologic carbon sequestration will shape the technology’s costeffectiveness and overall attractiveness. Key cradle-to-grave issues affecting liability include choice of liability regime, mandates for corrective action in case of leakage or accident, the need for insurance, and determination of potentially responsible parties. Rather than assuming that the existing...
