Standards Committee Working Group ANS-8.12 and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This standard is applicable to operations with plutonium-uranium oxide fuel mixtures outside nuclear reactors, except the assembly of these materials under controlled conditions, such as in critical experiments. Basic criteria are presented for plutonium-uranium fuel mixtures in single units of simple shape containing no more than 30 wt% plutonium combined with uranium containing no more than 0.71 wt% 235U. The limits for uniform aqueous mixtures (solution) are applicable to homogeneous mixtures and slurries in which the particles constituting the mixture are uniformly distributed and have a diameter no larger than 127 mm (0.005 in.), i.e., are capable of being passed through 120 mesh screen. This standard does not include the details of administrative controls, the design of processes or equipment, the description of instrumentation for process control, or detailed criteria to be met in transporting fissionable materials.

Book excerpt: The American National Standard on Nuclear Criticality Control and Safety of Plutonium-Uranium Fuel Mixtures Outside Reactors" (ANSI/ANS-8.12-1987 was approved for use on September 11, 1987. This standard represented a substantial revision of the previous standard (ANSI/ANS-8.12-1978), including the addition of heterogeneous systems to the homogeneous systems covered by the earlier standard. This paper will discuss the standard, including the scope, history, limit derivations, use of the limits and warnings regarding their use, and the future prospects for the standard.

Book excerpt: American National Standard ANSI/ANS-8.12-1987 (Ref. 1) was approved for use on September 11, 1987, The history of the development of the standard is discussed in Ref. 2. The first version of this standard, which included subcritical limits only on homogeneous plutonium-uranium fuel mixtures, was approved July 17, 1978. The current version was revised to add limits on heterogeneous systems (Ref., 3). This paper provides additional information on the limits presented in the standard.

Available in PDF, EPUB and Kindle. Book excerpt: This standard is applicable to operations outside of nuclear reactors with 235U, 233U, 239Pu, and other fissionalble materials in which shielding and confinement are provided for protection of personnel and the public. Criteria are provided that may be used for criticality safety controls under these conditions. This standard does not apply to the assembly of these materials under controlled conditions, such as in critical experiments. This standard does not include the details of administrative procedures for control, which are considered to be management prerogatives, details regarding the design of processes and equipment, or descriptions of instrumentation for process control.
