As depicted in Figure 4, reactors that have experi- enced year-plus outages can be found from sea to shining sea and plenty of points in-between.
Figure 5 shows that Alabama tops the list of states with the most year-plus reactor outages (six), followed closely by Michigan and New York with five each.
Figure 6 (p. 14) therefore plots the percent- age of a state’s reactors that have experienced year-plus outages. By this measure, Alabama still ranks worst, with a year-plus outage rate of 120 percent—the state’s five nuclear reactors experi- enced a total of six extended outages. Colorado, Maine, Maryland, Massachusetts, and Tennessee share a year-plus outage rate of 100 percent.
As in the case of reactor ownership, the raw numbers of outages by state may be unfair to Alabama because it had a larger fleet of operating reactors than many other states.
As depicted in (Figure 7, p. 15), most year- plus reactor outages have occurred in NRC Region I (Northeast) followed by Regions II (Southeast), III (Midwest), and IV and V
