Rising water temperatures and severe algae blooms in cooling canals have threatened to force the shutdown of two nuclear reactors at Florida Power & Light’s Turkey Point plant over the last few weeks.
The utility and federal regulators say there isn’t a public safety risk but the canal temperatures, climbing to 94 to 99 degrees, have come within one degree of a federal limit that would mandate an expensive shutdown at a time when power demands are soaring.
The hot water has also stoked the spread of algae through the 168-mile long canal system, which has helped keep temperatures high and reignited concerns about the power plant’s impact on water quality in Biscayne Bay.
Ever the good neighbor, FPL has a couple of solutions in mind:
In a letter last month to state regulators, the company asked to control the algae with herbicides and to cool the canals with daily injections of millions of gallons from an underground reservoir that supplies Miami-Dade County’s drinking water — requests that drew questions from Biscayne National Park and environmentalists.
Another FPL solution would do nothing to control the algae blooms:
FPL has also asked the Nuclear Regulatory Commission to raise the 100-degree operating limit to 104 degrees to keep the reactors on line.
Environmental concerns are nothing new for Turkey Point:
Worries over damage to the bay, now protected in a national park, have dogged the plant since FPL dug the sprawling canal system in the 1970s after environmentalists sued to stop billions of gallons of hot water from being pumped into the bay. Environmentalists also worried that a recent $3 billion overhaul of the plant, which allows FPL to generate up to 15 percent more power, could worsen the inland creep of an underground plume of saltwater that threatens drinking water well fields in South Miami-Dade County.
