The NUCLEAR HVAC UTILITY GROUP, herein referred to as NHUG, is a non-profit organization created to address technical issues associated with the Air Cleaning and Heating, Ventilating, and Air Conditioning (HVAC) systems at the United States and international Commercial Nuclear Power Plants. NHUG meets once a year to discuss HVAC related issues and to promote sharing of ideas, information, and operating experience.
NHUG is a Utility Group that promotes and achieves industry excellence through improved performance in the heating, ventilating, and air conditioning (HVAC) area through communication and training.
The first NHUG meetings were hosted by member Utilities consisting of SCE&G, Duke, TVA, Entergy, Niagra Mohawk while the HUG meetings were hosted by Commonwealth Edison and Sargent Lundy and were held in Chicago. Each group met twice per year. The two groups combined in 1995, and the new group was called NHUG. NHUG was incorporated in 1997 in Illinois with charter and bylaws.
