This could mean a couple things.  Modern nuclear plants separate the water around the reactor from the water used to transfer heat to the turbines.  I know water is used to watch radioactive particulate off of things.  I don't <b>think</b> water itself can be irradiated but it can carry radioactive material in it.  So if it's filtered, then I suppose it'll be fine.<br><br>If it's from the turbines, then that's just water.<br><br>Let's see what the video has to say and how close I got.<br><br>- Addendum -<br><br>Oh, it's a geothermal power plan.  That's...  Significantly less exciting.<br><br>Yes.  Yes, you can swim in that.  Dumb question.
