American Nuclear Society

ANS is a not-for-profit, international, scientific and educational organization. All ANS Standards receive dual approval from the American National Standards Institute and are thus considered American National Standards. ANS has written and approved nearly 150 different standards, and numerous versions of many of those. These technical documents are written, reviewed, and approved by the army of talented volunteers that support our program. ANS has close to 1,000 volunteers who provide their experience and expertise to the various levels of standards committees to see that these important documents are written for the industry's needs.
