Holtec hits milestones in Palisades restart, new reactor projects

The restart of Palisades nuclear power plant in Covert, Mich., has hit a milestone with the passivation of its primary system, plant owner Holtec International announced Monday, even as a firm restart date has yet to be announced.
Passivation is a chemical process that improves corrosion resistance by making plant materials less reactive. During the process, the reactor’s primary system was brought to normal operating temperature and pressure. Holtec called this passivation phase an “essential step” in maintaining the long-term reliability of equipment.

Europe and the Far East have been using refuse-to-energy plants to power turbine generators in the production of electricity. If the U.S. would convert the total municipal refuse to energy at normal efficiency, 6% of the total U.S. electric production could be produced. Pelletized solid waste [refuse-derived fuel (RDF)] can be mixed with coal and burned in existing industrial spreader stoker-fired boilers. An RDF-to-coal volume ratio of 1:1 corresponding to a weight ratio of 40:60 and an energy ratio of 23:77 was burned in a completely unmodified steam plant without unusual variations in equipment operation for a 24-h period. In addition, there was significant reduction in both SO2 and HC emissions compared to low-sulfur coal. Difficulties were experienced with an RDF-to-coal volume ratio of 2:1. Control data were established for comparative purposes by burning coal for a 24-h period.
