法国EDF，为什么要限制某些核电站排放热水

法国EDF限制某些核电站排放热水，是因为冷却水给二回路降温后温度高于40度，排出会对当地河流的生物产生影响。所以不是水无法直接冷却反应堆，而是冷却后无法排放，也算间接的“无法冷却“。

If the collected water becomes too hot, it can be discharged into rivers and seas, but doing so can cause environmental challenges as EDF recently noted after they announced that it will be reducing the power output from numerous nuclear reactors in France due to heatwaves.

Specifically, the increase in ambient temperatures (exceeding 40C) has resulted in rivers becoming warmer, and dumping warm water back into rivers has the potential to affect local wildlife. As aquatic life is highly sensitive to water temperatures, warmer waters can see wildlife die off, invasive species grow out of control, and disrupt food chains.
