Stop reading the tabloids and get your information straight. The "600,000 gallons of tritium steam" is pure crap. The steam that was released was steam from the secondary water loop which run the steam turbines. You should learn a little about how these nuclear plants actually work if you are so worried about them. You see, there are 2 main water loops, the primary water loop which goes into the reaction chamber and is heated by the nuclear reaction, and the secondary loop which is heated by the hot water from the primary loop (think like a car radiator where there are pipes running back and forth to disperse the heat to all the metal fins and into the air, but instead of there being just one long tube in the radiator, there are 2 separate tubes, one with the highly heated water from the reaction, the other with cool water that just came from the cooling tower).
So in other words, water that doesn't touch the reactor was vented as steam. So instead of reading tabloids and other such sources that simply are trying to sell a paper or generate a click on an article, you might want to read the real information like an official report or given how bad the reporting on the incident was, a official corrections release by the government showing how bad the reporting was in certain "press" coverage of the incident: Official NRC Letter of Corrections to Editor of New York Daily News
Again, since you live there, you should know that there is a history of New York not liking nuclear plants. In fact, New York hates them so much that the state of New York refused to sign any evacuation plans for a plant, causing the operator to not be able to turn it on. Approx 16% of every dollar Long Island Electric collects is being used to pay for that plant still to this day, along with a 5% rate increase every year for 10 years straight that happened all because of how anti-nuclear New York had become.
