Virginia utility considers SMRs
Dominion Energy Virginia has issued a request for proposals from leading nuclear companies to study the feasibility of putting a small modular reactor at its North Anna nuclear power plant.
While the utility says it is not a commitment to build an SMR at the site, the RFP is “an important first step in evaluating the technology and the North Anna site to support Dominion Energy customers’ future energy needs consistent with the company’s most recent Integrated Resource Plan.”

The dynamic behavior of the failed steam generator tube plug of an operational plant in 1989 can be understood through an analysis that solves the energy equation of the broken plug top and computes its kinetic energy as a function of elevation in the tube. The computed high kinetic energy of the plug top when it reaches the U-bend of the tube can exceed the work required to penetrate the tube wall at that location. If the inlet flow area at the bottom of the tube is small, the plug top exhibits an interesting stop-and-reacceleration behavior.
