We explore how nuclear shut-downs in the United States could affect air pollution, climate and health with existing and alternative grid infrastructure. We develop a dispatch model to estimate emissions of CO 2 , NO x and SO 2 from each electricity-generating unit, feeding these emissions into a chemical transport model to calculate effects on ground-level ozone and fine particulate matter (PM 2.5 ). Our scenario of removing nuclear power results in compensation by coal, gas and oil, resulting in increases in PM 2.5 and ozone that lead to an extra 5,200 annual mortalities. Changes in CO 2 […]
