Alpha Nu Sigma

Alpha Nu Sigma (ΑΝΣ) is an American nuclear engineering honor society affiliated with the American Nuclear Society. Alpha Nu Sigma was established to "recognize high scholarship, integrity, and potential achievement among outstanding degree-seeking nuclear engineering students at institutions of higher learning". As of fall 2021, there are 18 active chapters and approximately 2,000 members nationwide.

History
Alpha Nu Sigma National Honor Society was established by the American Nuclear Society on June 5, 1979. Alpha Nu Sigma quickly grew in size, obtaining 17 chapters and 320 members by its third anniversary in June 1982. By the end of 1985, Alpha Nu Sigma had grown to 23 chapters and 920 members. The Chernobyl disaster occurred in 1986, and growth of the society has struggled since that event.
