This study constructs a potential risk index(PRI) for the 65 U.S.-based commercial nuclear power plant(NPP) sites in relation to their surrounding populations. Four risk levels are defined: low risk, moderate risk,high risk, and very high risk. Discrepancies that exist in the sociodemographic characteristics of the host communities’ populations are examined as sorted by risk-level category.It is found that a greater percentage of minority groups are exposed to the highest levels of risk. In addition, percent “Hispanic” and percent “Other,”a grouping that includes multiracial, mixed, interracial, as well as Hispanic and Latino groups(for example, Mexican, Puerto Rican,Cuban, or Spanish) are categories that show the greatest percent change in both the period 1990–2000 and2000–2010.
