Radioactivity is scary; but this is one of those stories that are out of sync with reality.
Different countries have varying standards of what is considered safe levels of tritium in drinking water, but they are all within a bandwidth that guarantees any effect is so small so as to be undetectable. To put this leak in perspective, the tritium level in the worst monitoring well is just four times the level that Australia allows in their drinking water.
The tritium release is not affecting any local community, businesses, or homes and the tritiated water is being absorbed into the Hudson River where it is then quickly dispersed into the Atlantic Ocean. Once released into the Hudson the increased radiation is indiscernible from normal background levels. And given its 12 year half-life, it has virtually no effect on the environment.
Indian Point produces over 16,000 GWh of electricity per year. If Indian Point is closed, the additional carbon burden on the climate would be 9 million tons of CO2 per year. Once carbon is released into the atmosphere, it contributes to global warming for the many hundreds of years it takes to be removed
I understand that many people are philosophically opposed to nuclear power under any circumstances, but global warming is a potentially existential threat to humanity and Indian Point is still a source of zero carbon energy. Any arguments that may lead eliminating a zero carbon energy source thereby increasing global warming should be carefully scrutinized.
