About Arnold Gundersen

Born 1949. Arnold Gundersen is an American engineer.

Arnold "Arnie" Gundersen (born January 4, 1949, in Elizabeth, New Jersey where he was a nuclear engineering graduate student.

Gundersen questioned the safety of the Westinghouse AP1000, a 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 litigation after the Three Mile Island accident and has provided commentary on the Fukushima Daiichi nuclear disaster.

Background 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. 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.

Career 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.

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. in 2007 he became Mathematics Professor at Community College of Vermont. and on the board of directors for Fairewinds Energy Education, a 501c3 non-profit organization.

AP1000 In April 2010, Gundersen released a report (commissioned by several nongovernment organizations) 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. 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".

Vermont Yankee 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". 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.

Fukushima As part of Fairewinds Energy Education, Gundersen has hosted numerous videos and provided updates about the Fukushima Daiichi nuclear disaster. He was also a regular guest on media outlets such as Democracy Now and CNN discussing the issue. In an interview with Al Jazeera, Gundersen referred to Fukushima as "the biggest industrial catastrophe in the history of mankind".

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.

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.

Committee Chairman Senator John Glenn: "... what is the NRC doing to assure that Commission employees don't engage in potential conflict of interest practices?"

NRC Chairman Selin: "... it is true. Everything Mr. Gundersen said was absolutely right; he performed quite a service..." [stating that the conflict of interest issue is ] "much more troublesome because, to be frank, it's not just a question of who was paying for the lunches, but why these people were having lunch together in the first place. I mean it was the familiarization and the fraternization that was more worrisome... We are very concerned about this situation. We are sharpening our regulations, but in this case there is no question that the actions happened as described by the IG, people knew or should have known that they should not have done these actions... But that is a very worrisome situation- both of fraternization with the licensees and then the well-meaning but very dangerous practice of recommending people to licensees to help them solve problems."
