It was a beautiful spring day and, in the control room of the nuclear reactor, the workers decided to deactivate the security system for a systems test. As they started to do so, however, the floor of the reactor began to tremble. Suddenly, its 1,200-ton cover blasted flames into the air. Tons of radioactive radium and graphite shot 1,000 meters into the sky and began drifting to the ground for miles around the nuclear plant. The first firemen to the rescue brought tons of water that would prove useless when it came to dousing the fires. The workers wore no protective clothing and eight of them would die that night -- dozens more in the months to follow.
It was April 26, 1986, and this was just the start of the meltdown at the Chernobyl nuclear power plant in Ukraine, the worst nuclear accident of its kind in history. Chernobyl is ranked as a “level 7 event,” the maximum danger classification on the International Nuclear and Radiological Event Scale. It would spew out more radioactivity than 100 Hiroshima bombs. Of the 350,000 workers involved in cleanup operations, according to the World Health Organization, 240,000 would be exposed to the highest levels of radiation in a 30-mile zone around the plant. It is uncertain exactly how many cancer deaths have resulted since. The International Atomic Energy Agency’s estimate of the expected death toll from Chernobyl was 4,000. A 2006 Greenpeace report challenged that figure, suggesting that 16,000 people had already died due to the accident and predicting another 140,000 deaths in Ukraine and Belarus still to come. A significant increase in thyroid cancers in children, a very rare disease for them, has been charted in the region -- nearly 7,000 cases by 2005 in Belarus, Russia, and Ukraine.
In March 2011, 25 years after the Chernobyl catastrophe, damage caused by a tsunami triggered by a massive 9.0 magnitude earthquake led to the meltdown of three reactors at a nuclear plant in Fukushima, Japan. Radioactive rain from the Fukushima accident fell as far away as Ireland.
In 2008, the International Atomic Energy Agency had, in fact, warned the Japanese government that none of the country’s nuclear power plants could withstand powerful earthquakes. That included the Fukushima plant, which had been built to take only a 7.0 magnitude event. No attention was paid at the time. After the disaster, the plant’s owner, Tokyo Electric Power, rehired Shaw Construction, which had designed and built the plant in the first place, to rebuild it.
Near Misses, Radioactive Leaks, and Flooding
In both Chernobyl and Fukushima, areas around the devastated plants were made uninhabitable for the foreseeable future. In neither place, before disaster began to unfold, was anyone expecting it and few imagined that such a catastrophe was possible. In the United States, too, despite the knowledge since 1945 that nuclear power, at war or in peacetime, holds dangers of a stunning sort, the general attitude remains: it can’t happen here -- nowhere more dangerously in recent years than on the banks of New York’s Hudson River, an area that could face a nuclear peril endangering a population of nearly 20 million.
As the Fukushima tragedy struck, President Obama assured Americans that U.S. nuclear plants were closely monitored and built to withstand earthquakes. That statement covered one of the oldest plants in the country, the Indian Point Energy Center (IPEC) in Westchester, New York, first opened in 1962. One of 61 commercial nuclear plants in the country, it has two reactors that generate electricity for homes across New York City and Westchester County. It is located in the sixth most densely populated urban area in the world, the New York metropolitan region, just 30 miles north of Manhattan Island and the planet’s most economically powerful city.
The plant sits astride two seismic faults, which has prompted those opposing its continued operation to call for a detailed analysis of its capacity to resist an earthquake. In addition, a long series of accidents and ongoing hazards has only increased the potential for catastrophe. According to a report by the National Resources Defense Council (NDRC), if a nuclear disaster of a Fukushima magnitude were to strike Indian Point, it would necessitate the evacuation of at least 5.6 million people. In 2003, the existing evacuation plan for the area was deemed inadequate in a report by James Lee Witt, former head of the Federal Emergency Management Agency.
American officials have urged U.S. citizens to stay 50 miles away from the Fukushima plant. Such a 50-mile circle around IPEC would stretch past Kingston in Ulster County to the north, past Bayonne and Jersey City to the south, almost to New Haven, Connecticut, to the east, and into Pennsylvania to the west. It would include all of New York City except for Staten Island and all of Fairfield, Connecticut. “Many scholars have already argued that any evacuation plans shouldn’t be called plans, but rather ‘fantasy documents,’” Daniel Aldrich, a professor of political science at Purdue University, told the New York Times.
Paul Blanch, a nuclear engineer who worked in the industry for 40 years as well as with the Nuclear Regulatory Commission (NRC), thinks a worst-case accident at Indian Point could make the region, including parts of Connecticut, uninhabitable for generations.
According to a report from the Indian Point Safe Energy Coalition, there were 23 reported problems at the plant from its inception to 2005, including steam generator tube ruptures, reactor containment flooding, transformer fires, the failure of backup power for emergency sirens, and leaks of radioactive water laced with tritium. In the latest tritium leak, reported only last month, an outflow of the radioactive isotope from the plant has infused both local groundwater and the Hudson River. (Other U.S. nuclear plants have had their share of tritium leaks as well, including Turkey Point nuclear plant in Florida where such a leak is at the moment threatening drinking water wells.)
Experts agree that although present levels of tritium in groundwater near the plant are “alarming,” the tritium in the river will not be considered harmful until it reaches a far greater concentration of 120,000 picocuries per liter of water. (A picocurie is a standard unit of measurement for radioactivity.) Tritium is the lightest radioactive substance to leak from Indian Point, but according to an assessment by the New York Department of State, other potentially more dangerous radioactive elements like strontium-90, cesium-137, cobalt-60, and nickel-63 are also escaping the plant and entering both the groundwater and the river.
Representatives of Entergy Corporation, which owns the Indian Point plant, report that they don’t know when the present leak began or what its source might be. “No one has made a statement as to when the leak started,” wrote Paul Blanch in an email to us. “It could have started two years ago.” Nor does anyone seem to know where the leak is, how much radioactive matter is leaking, or how it can be stopped. The longer the leak persists, the greater the likelihood of isotopes more potent than tritium contaminating local drinking water.
According to David Lochbaum, director of the Nuclear Safety Project for the Union of Concerned Scientists (UCS) and once a trainer for NRC inspectors, the danger of flooding at the reactor should be an even greater focus of concern than radioactive substance outflows, since it could result in a reactor core meltdown. Yet despite repeated calls for Indian Point’s shutdown from the early 1970s on, it keeps operating.
On April 2, 2000, the NRC rated one of Indian Point’s two reactors the most troubled in the country, and it has been closed for lengthy periods because of system failures of various sorts. This, it turns out, is typical of Entergy-owned reactors. There were 10 “near-miss” incidents at U.S. nuclear reactors last year, a majority of them at three Entergy plants, according to a UCS report on nuclear plant safety. A near-miss incident is an event or condition that could increase the chance of reactor core damage by a factor of 10 or more. In response, the Nuclear Regulatory Commission must send an inspection team to investigate.
The number of such incidents has declined since UCS initiated its annual review in 2010, “overall, a positive trend,” according to report author Lochbaum. “Five years ago, there were nearly twice as many near misses. That said, the nuclear industry is only as good as its worst plant owner. The NRC needs to find out why Entergy plants are experiencing so many potentially serious problems.”Upstate New York’s Ginna plant, he adds, has been operating as long as Indian Point, but with only two “events” in its history. At Indian Point “there’s a major event every two to three years.”
What troubles Lochbaum more than anything else is Indian Point’s vulnerability to flooding. “There was a problem in May 2015 where a transformer exploded,” he told us. “There was an automatic fire sprinkler system installed to put this out. But it ended up flooding the building adjacent to where the explosion had taken place. Fortunately a worker noticed that an inch or two of water had accumulated. If the room had flooded up to five inches, all the power in the plant would have been lost. It would have plunged unit 3 into a ‘station blackout.’”
This might indeed have led to some kind of Fukushima-on-the-Hudson situation. In Fukushima, after the earthquake wiped out the normal power supply and tsunami floodwaters took away the backup supply, workers were unable to get cooling water into the reactor cores and three of the plant’s six reactors melted down.
In 2007, when Indian Point’s plant owner applied to the NRC for a 20-year extension of the plant’s operating license, it was found that a flood alarm could be installed in the room in question for about $200,000. As Lochbaum explains, “The owner determined it was cost-beneficial, that if they installed this flood alarm... it [would reduce] the risk of core meltdown by 20%, and [reduce] the amount of radiation that people on the plant could be exposed to by about 40%, at a cost of about two cents per person for the 20 million people living within 50 miles of the plant.” But nine years later, he told us, that flood alarm has still not been installed.
Potential Pipeline Explosions
As if none of this were enough, a new set of dangers to Indian Point have arisen in recent years due to a high-pressure natural gas pipeline currently being built by Spectra Energy. Dubbed the Algonquin Incremental Market (AIM) pipeline, it is to carry fracked natural gas from the Marcellus Shale formation underlying New York and adjacent states to the Canadian border. At 42 inches in diameter, this pipeline is the biggest that can at present be built -- and here’s the catch: AIM is slated to pass within 150 feet of the plant’s reactors.
A former Spectra worker hired to help oversee safety during the pipeline’s construction told a reporter that the company had taken dangerous shortcuts in its rush to begin the project. He had witnessed, he said, “at least two dozen” serious safety violations and transgressions.
Taking shortcuts in pipeline construction could, in the end, prove a risky business. Pipeline ruptures are the commonest cause of gas explosions like the one that, in March 2014 in Manhattan’s East Harlem, killed eight, injured 70, and leveled two apartment buildings. Robert Miller, chairman of the National Association of Pipeline Safety Representatives, attributed the rising rates of such incidents in newly constructed pipelines to “poor construction practices or maybe not enough quality control, quality assurance programs out there to catch these problems before those pipelines go into service."
In January 2015, the National Transportation Safety Board published a study documenting that gas accidents in “high-consequence” areas (where there are a lot of people and buildings) have been on the rise. With the New York metropolitan area so close to Indian Point, it seems odd indeed to independent experts that the nuclear plant with the sorriest safety history in the country has been judged safe enough for a high-pressure gas pipeline to be run right by it.
A hazards assessment replete with errors was the basis for the go-ahead. Richard B. Kuprewicz, a pipeline infrastructure expert and incident investigator with more than 40 years of energy industry experience, has called that risk assessment “seriously deficient and inadequate.”
At another nuclear plant subsequently shut down, as David Lochbaum points out, a rigorous risk analysis was conducted for possible explosions based on a worst-case scenario. (“I couldn’t think of any scenario that would be worse than what they presumed.”) At Indian Point, the risk analysis was, however, done on a best-case basis. Among other things, it assumed that any pipeline leak around the plant could be stopped in less than three minutes -- an unlikelihood at best. “It’s night and day. They did a very conservative analysis for [the other plant] and a very cavalier best-case scenario for Indian Point... I don’t know why they opted for [this] drive-by analysis.”
Of all the contaminants released in this industrial world, radioactivity may, in a sense, be the least visible and least imaginable, even if the most potentially devastating, were something to go wrong. As a result, the dangers of the “peaceful” atom have often proved hard to absorb before disaster strikes -- as at the Three Mile Island reactor near Middletown, Pennsylvania, on March 28, 1979. Even when such a power plant sits near a highway or a community, it’s usually a reality to which people pay scant attention, in part because nuclear science is alien territory. This is why safety at nuclear power plants has been something citizens have relied on the government for.
The history of Indian Point, however, offers a grim reminder that the government agencies expected to protect citizens from disaster aren’t doing a particularly good job of it. Over the past several years, for instance, residents in the path of the AIM pipeline project have begun accusing the Federal Energy Regulatory Commission (FERC) of overwhelming bias in the industry’s favor. As FERC has a corner on oversight and approval of all pipeline construction, this is alarming. Its stamp of approval on a pipeline can only be contested via appeals that lead directly back to FERC itself, as the Natural Gas Act of 1938 gave the agency sole discretion over pipeline construction in the U.S. Ever since then, its officials have approved pipelines of every sort almost without exception. Worse yet, at Indian Point, the Nuclear Regulatory Commission joined FERC in green-lighting AIM.
During the two-and-a-half-year period in which the pipeline was approved and construction began, the mainstream media virtually ignored the project and its potential dangers. Only this February, when New York Governor Andrew Cuomo, who has been opposed to the relicensing of Indian Point, first raised concerns about the dangers of the pipeline, did the New York Times, the paper of record for the New York metropolitan area, finally publish a piece on AIM. So it fell to a grassroots movement of local activists to bring AIM’s dangers to public attention. Its growing resistance to a pipeline that could precipitate just about anything up to a Fukushima-on-the-Hudson-style event evidently led Governor Cuomo to urge FERC to postpone construction until a safety review could be completed, a request that the agency rejected. In February, alarmed by reports of tritium leaking from the plant, the governor also directed the state’s departments of environmental conservation and health to investigate the likely duration and consequences of such a leak and its potential impacts on public health.
According to Paul Blanch, the risk of a pipeline explosion in proximity to Indian Point is one in 1,000, odds he believes are too high given what’s potentially at stake. (He considers a one-in-a-million chance acceptable.) "I've had over 45 years of nuclear experience and [experience in] safety issues. I have never seen [a situation] that essentially puts 20 million residents at risk, plus the entire economics of the United States by making a large area surrounding Indian Point uninhabitable for generations. I'm not an alarmist and haven't been known as an alarmist, but the possibility of a gas line interacting with a plant could easily cause a Fukushima type of release."
According to Blanch, attempts to regulate nuclear plants after a Fukushima- or Chernobyl-type catastrophe are known in the trade as “tombstone regulation.” Nobody, of course, should ever want to experience such a situation on the Hudson, or have America’s own mini-Hiroshima seven decades late, or find literal tombstones cropping up in the New York metropolitan area due to a nuclear disaster. One hope for preventing all of this and ensuring protection for New York’s citizenry: the continuing growth of impressive citizen pressure and increasing public alarm around both the pipeline and Indian Point. It gives new meaning to the phrase “power to the people.”
