ANSI/ANS-8.7-1975(R87): Guide for nuclear criticality safety in the storage of fissile materials

Basic parameters and guidance for the nuclear criticality safety control outside reactors are described in American National Standards Institute/American Nuclear Society (ANSI/ANS)-8.1-1983(R88), {open_quotes}Nuclear Criticality Safety in Operations with Fissionable Materials Outside Reactors.{close_quotes} Because ANS-8.1 provides general guidance and limited single-unit parameter limits, ANS standards subcommittees developed the current ANSI/ANS-8.7-1975, {open_quotes}Guide for Nuclear Criticality Safety in the Storage of Fissile Materials,{close_quotes} which was reaffirmed in 1987. The standard is being revised, and the new revision is to be completed by December 1997. It is therefore appropriate that the standard and its technical bases be summarized, the applications highlighted, and the plans for further development explained.
