Anti-nuclear activist Michael Mariotte dies at age 63

Michael Mariotte, the president and former executive director of Nuclear Information and Resource Service (NIRS) has died of cancer at age 63, the Washington Post reported May 23.

The newspaper reported that the anti-nuclear activist had died at his home in Maryland May 16 after suffering with pancreatic cancer. NIRS is a leading critic of nuclear energy both in the United States and internationally.

Mariotte’s death was also reported by the Washington City Paper, an alternative newspaper where Mariotte once worked as an editor.

Mariotte was executive director of NIRS from October 1986 through December 2013. He began at NIRS in February 1985 as editor and founder of The Nuclear Monitor. “He has made numerous television appearances and has been widely quoted in the press,” according to a biography posted on the NIRS website.

Over the years, Mariotte and NIRS have been active in bringing many administrative cases before the Nuclear Regulatory Commission (NRC). In 2013, Mariotte praised NRC commissioners for upholding the denial of a nuclear facility license because of foreign ownership. In 2014, NRC denied a petition by NIRS that sought to expand the existing emergency planning zones (EPZ) from 10 miles to at least 25 miles around nuclear plants.

Mariotte has also testified a number of times before the U.S. Congress, and certain international legislative bodies about nuclear energy concerns. He was a graduate of Antioch College.
