All currently active ones perhaps, but Trawsfynydd had a lake.

"Built in the 1960s, Trawsfynydd started service in 1965 and generated
electricity for 26 years before it reached the end of its service life
in 1991. Trawsfynydd was the first inland civil Magnox nuclear power
station and drew its cooling water, at the rate of 35 million gallons
an hour, from the man-made Trawsfynydd lake, originally built in the
1920s as part of a hydro electric project at Maentwrog."

It was a bit more than a few days.

"During the extreme heat of 2003 in France, 17 nuclear reactors
operated at reduced capacity or were turned off. Électricité de France
was forced to buy power from neighboring countries on the open market,
where demand drove the price of a megawatt hour as high as EURO 1,000, or
$1,350. Average prices in France during summer months ordinarily are
about EURO 95 per megawatt hour.
The heat wave cost Électricité de France an extra EURO 300 million. The
state-owned company "swallowed it as a one-off cost of doing business
in extreme circumstances," Philippe Huet, an executive vice president
at Électricité de France, said."
That sort of summer will be routine by the 2030s. (Fergus?)
