The Institute of Nuclear Power Operations (INPO), headquartered in Atlanta, GA, is an organization established in 1979 by the U.S. nuclear power industry in response to recommendations by the Kemeny Commission Report, following the investigation of the Three Mile Island accident.

INPO conducts plant evaluations at nuclear stations and identifies both strengths and areas for improvement that are intended to be shared with other nuclear stations as a method to share best practices and common weaknesses.

[citation needed] Advisory Council members have included Dr. Edgar H. Schein, a retired MIT professor who is widely credited with inventing the term "corporate culture;" and Dr. Rodger Dean Duncan, an organizational development and human performance expert.

Retired U.S. Navy vice-admiral Eugene Parks Wilkinson, the first commanding officer of the nuclear powered submarine USS Nautilus, was selected as INPO's first CEO in 1980, and served in that position until 1984.

The lobby of INPO's headquarters is centered on a marble pedestal upon which is chiseled the word "EXCELLENCE," with the final E unfinished.
