Indian Point tritium leak 80% worse than originally reported
New measurements at the Indian Point nuclear power plant in upstate New York show levels of radioactive tritium 80 percent higher than reported last week. Plant operator insists the spill is not dangerous, as state officials call for a safety probe.
Entergy, which operates the facility 25 miles (40 km) north of New York City, says the increased levels of tritium represent “fluctuations that can be expected as the material migrates.”
“Even with the new readings, there is no impact to public health or safety, and although these values remain less than one-tenth of one percent of federal reporting guidelines,” Entergy said in a statement.
New York governor Andrew Cuomo raised an alarm last Saturday over the reports of groundwater contamination at Indian Point, noting that the company reported “alarming levels of radioactivity” at three monitoring wells, with “radioactivity increasing nearly 65,000 percent” at one of them.
The groundwater wells have no contact with any drinking water supplies, and the spill will dissipate before it reaches the Hudson River, a senior Entergy executive argued Tuesday, suggesting the increased state scrutiny was driven by the company’s decision to shut down another nuclear power plant.

“There are a number of stakeholders, including the governor, who do not like the fact that we are having to close Fitzpatrick,” Michael Twomey, Entergy’s vice president of external affairs, said during an appearance on ‘The Capitol Pressroom,’ a show on WCNY public radio.
The James A. Fitzpatrick plant is located on the southern shore of Lake Ontario, near Oswego, New York. Entergy said it intended to close the plant once it runs out of fuel sometime this year, citing its continued operations as unprofitable.
"We’re not satisfied with this event. This was not up to our expectations,” Twomey said, adding that the Indian Point spill should be seen in context.
Though it has never reported a reactor problem, the Indian Point facility has been plagued by issues with transformers, cooling systems, and other electrical components over the years. It currently operates two reactors, both brought on-line in the 1970s.
In December, the federal Nuclear Regulatory Commission allowed Entergy to continue operating the reactors, pending license renewal. The facility’s initial 40-year license was set to expire on December 12, but the regulators are reportedly leaning towards recommending a 20-year extension.
By contrast, Reactor 4 at the Chernobyl Nuclear Power Plant in Pripyat, Ukraine was only three years old when it exploded in April 1986. To this day, an area of 1000 square miles around the power plant remains the “exclusion zone,” where human habitation is prohibited.
The tritium leak at Indian Point most likely took place in January, during the preparations to shut down Reactor 2 for refueling, according to Entergy. Water containing high levels of the hydrogen isotope reportedly overfilled the drains and spilled into the ground.
According to Entergy, tritium is a “low hazard radionuclide” because it emits low-energy beta particles, which do not penetrate the skin. “People could be harmed by tritium only through internal exposure caused by drinking water with high levels of tritium over many years,” an Entergy fact sheet says.
Environmentalist critics are not convinced, however.
“This plant isn’t safe anymore,” Paul Gallay, president of environmental watchdog group Riverkeeper, told the New York Daily News. “Everybody knows it and only Entergy and the Nuclear Regulatory Commission refuse to admit it.”
