ANSI/ANS-1-2000;R2007;R2012 (R = Reaffirmed): Conduct of Critical Experiments

"R" in the numeric designation signifies that the 2000 standard was reaffirmed (recertified) as an American National Standard in 2007 & 2012.  No changes can be made to a standard during reaffirmation.

This standard provides for the safe conduct of critical experiments.  Such experiments study neutron behavior in a fission device where the energy produced is insufficient to require auxiliary cooling, and the power history is such that the inventory of long-lived fission products is insignificant.
