As far as tritium releases go nuclear plants are allowed to release trtium. There are EPA established limits for how much tritium a nuclear plant can release. A similar tritium leak cause a large amount of press at the Braidwood station in Illinois (1,600 picocuries Source: http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/tritium-radiation-fs.html) This tritium leak was the equivilent as one one thousand the level of background radiation. So it was 1000 times more dangerous to be alive anywhere in the US (except at higher elevation, you are exposed to more radiation at higher elevation) than drink water from the release site. Tritium releaeses are typically used to scare people away from nuclear, but in a scientific way have not shown any significance. I am not familiar with the levels that were released at Vermont Yankee but I would assume it is similar to Braidwood.
People who work in the nuclear industry know we are one accident away from having all plants shut down. Due to this there is a really strong safety culture. I dont know why someone would lie about any issues knowing it could have such large concequences. I am not making excuses, but if you have ever seen a diagram of pipes in a nuclear plant it is HUGE. A nuclear plant costs between 5 and 10 BILLION dollars to build without fuel. That is a HUGE amount of pipes. It is possible that someone at a plant wasnt aware of a pipe they are not responsible for and misspoke.
Also all ground water has tritium, but I believe ocean water has a higher percentage of tritium but there is tritium in all water. So you drink tritium everyday (as well as walk past tritium filled exit signs, americium smoke detectors, and breath radon filled air etc). You are exposed to radiation all the time, the press just doesnt focus on thing like flying causing you to be exposed to a higher level of raditation because it doesnt make as good of a story.
