I picked another earlier year at random from the EIA production database
of 1980. For that year the capacity was 66% owing including the spring
refueling outages at two units that particular year. That would lead to
another high capacity factor year the following as there would be no
outage the subsequent year needed.

Didn't think to look at Rancho Seco from the same database--in 1980 it
produced 4,425,923 KWhr w/ listed capacity of 963 MWe. That works out
to 52.5% but there was again, an outage during Feb-Apr. Ratioing those
three months the plant had a not great operating CF of 70% the rest of
the year.

As noted, the Oconee Station demonstrates that these units with good
operating practices can make 85% CF.
