TVA nominees promise to support advanced reactor development
Four nominees to serve on the Tennessee Valley Authority Board of Directors told the Senate Environment and Public Works Committee that they support the build-out of new advanced nuclear reactors to meet the increased energy demand being shouldered by the country’s largest public utility.

PDP is a very interesting phenomenon and presents a significant problem to the fuel control and the safety in Tokamak devices. Systematic experimental studies on the PDP mechanism using an ECR discharge plasma have been carried out to investigate the role of the neutrals and to estimate the isotope effects occurred in PDP for H, D, and T. The maximum isotope effects observed are 1.42 for H/D, and 1.1 for a D/T mixed plasma in the case of SUS 304 test membrane. The magnitudes of the isotope effects between the three hydrogen isotopes are satisfactorily explained by the role of neutrals in PDP.
