Arnold "Arnie" Gundersen (born January 4, 1949, in Elizabeth, New Jersey [1] ) is a former nuclear industry executive, and engineer with more than 44 years of nuclear industry experience who became a whistleblower in 1990. Gundersen has written dozens of expert reports for nongovernment organizations and the state of Vermont. [2] Gunderson was a licensed reactor operator from 1971-1972 on Rensselaer Polytechnic Institute's zero-power open-pool university research reactor at the Reactor Critical Facility in Schenectady, New York, [3] where he was a nuclear engineering graduate student. [4] [5]
Gundersen questioned the safety of the Westinghouse AP1000, a proposed third-generation nuclear reactor and has expressed concerns about the operation of the Vermont Yankee Nuclear Power Plant. He served as an expert witness in the investigation of the Three Mile Island accident [6] and has provided commentary on the Fukushima Daiichi nuclear disaster. [7] [8] [9]
Gundersen is a graduate of the Rensselaer Polytechnic Institute (1971), with a B.S. cum laude and a GPA of 3.74 in nuclear engineering, holds a master's degree in nuclear engineering, and gained an Atomic Energy Commission Fellowship (1972). Gundersen has more than 40 years of nuclear power engineering experience.[ clarification needed ][ citation needed ] Gundersen holds a nuclear safety patent, was a licensed reactor operator, and is a former nuclear industry senior vice president. During his nuclear power industry career, Gundersen also managed and coordinated projects at 70 nuclear power plants in the US. [1] [2] [10]
From 1972 to 1976 Gundersen worked at the Northeast Utilities Service Corporation as a nuclear engineer; and from 1976 to 1979 at New York State Electric & Gas as an engineering supervisor. [1] From 1979 to 1990 Gundersen was employed at Nuclear Energy Services, a Danbury, Connecticut-based consulting firm. [1] Gundersen served as an expert witness in the investigation of the 1979 Three Mile Island accident. [6] He co-authored the DOE Decommissioning Handbook, First Edition (1981–82). [1]
In 1990 Gundersen was a senior vice president at Nuclear Energy Services when he discovered radioactive material in an accounting safe. Three weeks after notifying the company president of what he believed to be radiation safety violations, Gundersen was fired. According to The New York Times , for three years, Gundersen was "awakened by harassing phone calls in the middle of the night" and "became concerned about his family's safety". Gundersen believes he was blacklisted, harassed and fired for doing what he thought was right. [2]
While also writing numerous nuclear expert reports from 1993 to 2008, Gundersen was employed at a number of Connecticut schools teaching mathematics and physics; [1] [11] in 2007 he became Mathematics Professor at Community College of Vermont. [1]
Gundersen is chief engineer of Fairewinds Associates, and on the board of directors for Fairewinds Energy Education a 501c3 non-profit organization.

In April 2010, Gundersen released a report (commissioned by several nongovernment organizations[ who? ]) which explored a hazard associated with the possible rusting through of the AP1000 containment structure steel liner. In the AP1000 design, the liner and the concrete are separated, and if the steel rusts through, "there is no backup containment behind it" says Gundersen. [12] If the dome rusted through the design would expel radioactive contaminants and the plant "could deliver a dose of radiation to the public that is 10 times higher than the N.R.C. limit" according to Gundersen. Westinghouse has disputed Gundersen’s assessment. [12] Gundersen has testified before the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards saying that "if a hole appeared, the chimney effect would disperse radioactive material far and wide". [13]
In 2010 Gundersen expressed concerns about the operation of the Vermont Yankee Nuclear Power Plant, saying a leak of radioactive tritium there could be "followed by releases of other, more dangerous materials if the plant keeps operating". [14] The plant ceased operations in 2014 and is currently in the process of nuclear decommissioning.
Gundersen has said that the U.S. nuclear industry and regulators need to reexamine disaster planning and worst-case scenarios, especially in reactors such as Vermont Yankee, which have the same design as the crippled nuclear plant at the center of the 2011 Japanese Fukushima nuclear emergency. He has stated that Vermont Yankee and similar plants are vulnerable to a similar cascade of events as in Japan. [15]
As part of Fairewinds Energy Education, Gundersen has hosted numerous videos and provided updates about the Fukushima Daiichi nuclear disaster. [16] [17] He was also a regular guest on media outlets such as Democracy Now and CNN discussing the issue. [7] [8] [18] In an interview with Al Jazeera, Gundersen referred to Fukushima as "the biggest industrial catastrophe in the history of mankind". [19]
In September 2013 Gundersen accused the Japanese government of lying in order to secure its position as host of the 2020 Olympic Games when it claimed that the disaster was under control and that there existed no health concerns. The plant, Gundersen said, "is leaking into the Pacific Ocean extensively" and that thyroid cancers, deformed fish and radioactive animals were being discovered. [20]
In early October 2013, Gundersen stated that due to newly discovered leaks and impending tropical storms, the potential existed for a release of radiation 15,000 times that of Hiroshima. [9]
A weeklong series in the December 1992 Cleveland Plain Dealer entitled "Lethal Doses: Radiation That Kills" alleged "extreme medical malpractice" in radiation medicine and accused the Nuclear Regulatory Commission of "serial failings to do anything about it". Runner-up for the Pulitzer Prize in 1993, the Plain Dealer’s five-part series alleged numerous of "misappropriation and sloppiness using nuclear material that led to disfigurement and death". One of the five parts cited Arnie Gundersen who alleged "botched inspections and cozy personal relationships between NRC inspectors and licensees". Two congressional investigations were held in response to this series in order to obtain NRC reform on the matter.[ citation needed ]

Arnie Gundersen has a relevant cameo appearance in the 2023 Documentary Film SOS: The San Onofre Syndrome directed by James Heddle, Mary Beth Brangan and Morgan Peterson. The film chronicles a community’s victory over leaking reactors, only to confront a chilling reality - deadly radioactive waste stranded next to a rising sea. At the press conference community activists held for the shut down of the San Onofre nuclear plant, the film shows Arnie Gundersen saying: "This has ramifications around the country. This is a seismic event in the nuclear industry."
The United States Nuclear Regulatory Commission (NRC) is an independent agency of the United States government tasked with protecting public health and safety related to nuclear energy. Established by the Energy Reorganization Act of 1974, the NRC began operations on January 19, 1975, as one of two successor agencies to the United States Atomic Energy Commission. Its functions include overseeing reactor safety and security, administering reactor licensing and renewal, licensing radioactive materials, radionuclide safety, and managing the storage, security, recycling, and disposal of spent fuel.
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011.
Vermont Yankee was an electricity generating nuclear power plant, located in the town of Vernon, Vermont, in the northeastern United States. It generated 620 megawatts (MWe) of electricity at full power. The plant was a boiling water reactor (BWR), designed by General Electric. It operated from 1972 until December 29, 2014, when its owner Entergy shut down the plant. In 2008, the plant provided 71.8% of all electricity generated within Vermont, amounting to 35% of Vermont's electricity consumption. The plant is on the Connecticut River, upstream of the Vernon, Vermont Hydroelectric Dam and used the reservoir pool for its cooling water.
The AP1000 is a nuclear power plant designed and sold by Westinghouse Electric Company. The plant is a pressurized water reactor with improved use of passive nuclear safety and many design features intended to lower its capital cost and improve its economics.
In the United States, nuclear power is provided by 94 commercial reactors with a net capacity of 97 gigawatts (GW), with 63 pressurized water reactors and 31 boiling water reactors. In 2019, they produced a total of 809.41 terawatt-hours of electricity, which accounted for 20% of the nation's total electric energy generation. In 2018, nuclear comprised nearly 50 percent of US emission-free energy generation.
Nuclear safety is defined by the International Atomic Energy Agency (IAEA) as "The achievement of proper operating conditions, prevention of accidents or mitigation of accident consequences, resulting in protection of workers, the public and the environment from undue radiation hazards". The IAEA defines nuclear security as "The prevention and detection of and response to, theft, sabotage, unauthorized access, illegal transfer or other malicious acts involving nuclear materials, other radioactive substances or their associated facilities".
Nuclear decommissioning is the process leading to the irreversible complete or partial closure of a nuclear facility, usually a nuclear reactor, with the ultimate aim at termination of the operating licence. The process usually runs according to a decommissioning plan, including the whole or partial dismantling and decontamination of the facility, ideally resulting in restoration of the environment up to greenfield status. The decommissioning plan is fulfilled when the approved end state of the facility has been reached.
Nuclear safety in the United States is governed by federal regulations issued by the Nuclear Regulatory Commission (NRC). The NRC regulates all nuclear plants and materials in the United States except for nuclear plants and materials controlled by the U.S. government, as well those powering naval vessels.
The Fukushima Daiichi Nuclear Power Plant is a disabled nuclear power plant located on a 3.5-square-kilometre (860-acre) site in the towns of Ōkuma and Futaba in Fukushima Prefecture, Japan. The plant suffered major damage from the magnitude 9.1 earthquake and tsunami that hit Japan on March 11, 2011. The chain of events caused radiation leaks and permanently damaged several of its reactors, making them impossible to restart. The working reactors were not restarted after the events.
The anti-nuclear movement in the United States consists of more than 80 anti-nuclear groups that oppose nuclear power, nuclear weapons, and/or uranium mining. These have included the Abalone Alliance, Clamshell Alliance, Committee for Nuclear Responsibility, Nevada Desert Experience, Nuclear Information and Resource Service, Physicians for Social Responsibility, Plowshares Movement, United Steelworkers of America (USWA) District 31, Women Strike for Peace, Nukewatch, and Women's International League for Peace and Freedom. Some fringe aspects of the anti-nuclear movement have delayed construction or halted commitments to build some new nuclear plants, and have pressured the Nuclear Regulatory Commission to enforce and strengthen the safety regulations for nuclear power plants. Most groups in the movement focus on nuclear weapons.
The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi nuclear power plant in Ōkuma, Fukushima, Japan which began on 11 March 2011. The proximate cause of the accident was the 2011 Tōhoku earthquake and tsunami, which resulted in electrical grid failure and damaged nearly all of the power plant's backup energy sources. The subsequent inability to sufficiently cool reactors after shutdown compromised containment and resulted in the release of radioactive contaminants into the surrounding environment. The accident was rated seven on the International Nuclear Event Scale by Nuclear and Industrial Safety Agency, following a report by the JNES. It is regarded as the worst nuclear incident since the Chernobyl disaster in 1986, which was also rated a seven on the International Nuclear Event Scale.
Fukushima Daiichi is a multi-reactor nuclear power site in the Fukushima Prefecture of Japan. A nuclear disaster occurred there after a 9.0 magnitude earthquake and subsequent tsunami on 11 March 2011. The earthquake triggered a scram shut down of the three active reactors, and the ensuing tsunami crippled the site, stopped the backup diesel generators, and caused a station blackout. The subsequent lack of cooling led to explosions and meltdowns, with problems at three of the six reactors and in one of the six spent-fuel pools.
The nuclear energy policy of the United States began in 1954 and continued with the ongoing building of nuclear power plants, the enactment of numerous pieces of legislation such as the Energy Reorganization Act of 1974, and the implementation of countless policies which have guided the Nuclear Regulatory Commission and the Department of Energy in the regulation and growth of nuclear energy companies. This includes, but is not limited to, regulations of nuclear facilities, waste storage, decommissioning of weapons-grade materials, uranium mining, and funding for nuclear companies, along with an increase in power plant building. Both legislation and bureaucratic regulations of nuclear energy in the United States have been shaped by scientific research, private industries' wishes, and public opinion, which has shifted over time and as a result of different nuclear disasters.
The Japanese reaction occurred after the Fukushima Daiichi nuclear disaster, following the 2011 Tōhoku earthquake and tsunami. A nuclear emergency was declared by the government of Japan on 11 March. Later Prime Minister Naoto Kan issued instructions that people within a 20 km (12 mi) zone around the Fukushima Daiichi nuclear plant must leave, and urged that those living between 20 km and 30 km from the site to stay indoors. The latter groups were also urged to evacuate on 25 March.
The Fukushima disaster cleanup is an ongoing attempt to limit radioactive contamination from the three nuclear reactors involved in the Fukushima Daiichi nuclear disaster that followed the earthquake and tsunami on 11 March 2011. The affected reactors were adjacent to one another and accident management was made much more difficult because of the number of simultaneous hazards concentrated in a small area. Failure of emergency power following the tsunami resulted in loss of coolant from each reactor, hydrogen explosions damaging the reactor buildings, and water draining from open-air spent fuel pools. Plant workers were put in the position of trying to cope simultaneously with core meltdowns at three reactors and exposed fuel pools at three units.
The Investigation Committee on the Accident at the Fukushima Nuclear Power Stations of Tokyo Electric Power Company was formed June 7, 2011 by the Japanese government as an independent body to investigate the March Fukushima Daiichi nuclear disaster. The Investigation Committee issued an interim report in December 2011, and issued its final report in July 2012.
The Fukushima Daiichi reactor, was 1 out of 4 reactors seriously affected during the Fukushima Daiichi nuclear disaster on 11 March 2011. Overall, the plant had 6 separate boiling water reactors originally designed by General Electric (GE), and maintained by the Tokyo Electric Power Company (TEPCO). At the time of the earthquake, Reactor 4 had been de-fueled while 5 and 6 were in cold shutdown for planned maintenance.

Overall, the plant had 6 separate boiling water reactors originally designed by General Electric (GE), and maintained by the Tokyo Electric Power Company (TEPCO). In the aftermath, Unit 3 experienced hydrogen gas explosions and suffered a partial meltdown, along with the other two reactors in operation at the time the tsunami struck. Reactor 4 had been de-fueled while 5 and 6 were in cold shutdown for planned maintenance.
The Fukushima Daiichi nuclear disaster genshiryoku hatsudensho jiko) was a series of equipment failures, nuclear meltdowns, and releases of radioactive materials at the Fukushima I Nuclear Power Plant, following the Tōhoku earthquake and tsunami on 11 March 2011. It is the largest nuclear disaster since the Chernobyl disaster of 1986.
The Rensselaer Polytechnic Institute (RPI) Reactor Critical Facility (RCF) has provided hands-on education and training for RPI and other student for almost a quarter of a century. The RCF was built in the 1950s by the American Locomotive Company (ALCO) as a critical facility in which to carry out experiments in support of the Army Package Power Reactor (APPR) program. A number of APPRs were built and operated. In the middle 1960s, ALCO went out of business and provided the facility to RPI. Since that time, RPI has operated the RCF primarily in a teaching mode in the nuclear engineering department, although limited amounts of reactor research, activation analysis, and reactivity assays have been carried out as well.
