NRC approves V.C. Summer’s second license renewal
Dominion Energy’s V.C. Summer nuclear power plant, in Jenkinsville, S.C., has been authorized to operate for 80 years, until August 2062, following the renewal of its operating license by the Nuclear Regulatory Commission for a second time.

Defueling operations at Three Mile Island Unit 2 involve underwater plasma arc cutting of reactor vessel stainless steel components. Sampling and analysis of released off-gases and aerosols during steady-state plasma arc cutting tests established a conversion fraction of nitrogen-to-nitrogen oxides, off-gas composition, and aerosol concentrations for engineering evaluations of potential health and safety and corrosion issues. The sample results indicate that (a) <1 vol% of nitrogen is converted to nitrogen oxides, (b) the airborne particulate concentrations for the major steel components (chromium, iron, nickel, etc.) could exceed the threshold limit values without off-gas capability, (c) the volume percent hydrogen could exceed its lower flammability limit without off-gas capability, and (d) there is low corrosion potential for off-gas system components for the given torch operations.
