Yes, minuscule amounts of Tritium, the least dangerous radionuclide there is. Calling water with some Tritium in it nuclear waste is like calling fingernail clippings medical waste. IE it's semantically accurate, but is misleading by accident or design. It's actually the safest thing to do with it, it essentially vanishes in the ocean it becomes so diluted. If this water spills on land and was all concentrated in a tiny little patch of groundwater, then there's a well, minuscule risk. Tritium is only a beta emitter (the radiation it releases won't pass through a piece of paper,) so it's harmless outside of the body. And it's hydrogen, which has a very short half life in the body, it's in and out of the body in days.
