from 67.5% to 46.3% in the aftermath of
Fukushima.
Most of the countries that had already
been achieving better than 90% capacity
held steady over 2011.
Availability by Country
The availability rankings continue to be
dominated by European countries (Table
3). Worldwide, most availability ratings
held steady or showed modest improvements
as demand returned. Japan, as
would be expected, showed a major drop
in 2011.
U.S. Nuclear Power Uprates
Five U.S. reactors received power uprate
approvals from the Nuclear Regulatory
Commission (NRC) in 2011, with three
of them being significant enhancements
(Table 4). Units 1 and 2 at the Point Beach
plant in Two Rivers, Wis., received approvals
for 17% uprates, while Unit 2 at
the Nine Mile Point plant in Scriba, N.Y.,
was approved for a 15% uprate.
In June of this year, the NRC approved
a 15% uprate for Units 3 and 4 at the TurTable
