E-Mail RICHLAND, Wash.--As the Clean Energy Transformation Act drives Washington state toward carbon-free electricity, a new energy landscape is taking shape. Alongside renewable energy sources, a new report finds small modular reactors are poised to play an integral role in the state's emerging clean energy future. The technology could help fill a power source gap soon to be left by carbon-emitting resources like coal and natural gas, which will be phased out in coming years, according to a report composed by researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory and Massachusetts Institute of Technology. "Nuclear energy is a reliable source of baseload electricity," said PNNL's manager for nuclear power systems Ali Zbib, who coauthored the report, "and our findings show that advanced small modular reactors could be economically competitive in a future carbon-free electricity sector. They're well-suited to play an important role in an energy market that requires more flexibility."
