Cooling canal water at the Turkey Point nuclear reactor is reaching dangerous levels as the demand for energy increases.

FPL officials have asked the Nuclear Regulatory Commission to increase its operating limit to 104 degrees to stay online, but nuclear energy expert Arnie Gundersen says turbines aren't built to run with water that hot.

Gundersen says the higher temperatures are also killing fish.

He adds that FPL could either decrease the power output or shut down to get levels back to normal.

According to reps with FPL, they spoke with WIOD and say fish are not dying, and the turbines are in fact built to run with water that hot, but current licensing issues are restricting their efforts with the turbines.
