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.

An investigation was performed on possible penetration of sodium into Type-304L stainless-steel grain boundaries when the steel was exposed to the liquid metal at 1200°F. The method used consisted of progressive penetration with a laser through sodium-filled thin wall stainless-steel tubes ∼0.0005 in. at a time. Simultaneous recording of the emission spectrum of each sample on photographic film resulted in the production of a comparative record which was analyzed for the intensity of the sodium 5890 and 5895.5 Å doublet. Entry into a sodium-rich region was attended with intensification of the sodium lines. Results with a series of tubes exposed to sodium at 1200°F up to 1425 h and compared with a control sample not treated at 1200°F did not show any evidence of sodium penetration through Type-304L stainless steel.
