Radioactive Leak at Indian Point Nuclear Plant Shows ‘We Are Flirting With Catastrophe’ (Source ecowatch.com) New York Gov. Andrew Cuomo has called for Indian Point nuclear power plant to be shut down after officials discovered that a radioactive material known as tritium was leaking into the groundwater. On Feb. 6, Cuomo ordered an investigation into the leak after Entergy, the company that operates the plant, reported “alarming levels of radioactivity at three monitoring wells, with one well’s radioactivity increasing nearly 65,000 percent,” according to a statement from the governor. Last week, Cuomo called for a more thorough investigation after officials found the leak had spread by 80 percent. Now the governor and lawmakers across the Hudson Valley have called for the plant to close.
