A. INTRODUCTION
Part 70 of the Atomic Energy Commission'sregulations requires each licensee to maintain materialcontrol and accounting procedures for the specialnuclear material in his possession under license. A keycomponent of such a system is an accurate, measuredmaterial balance. A significant factor in obtaining such amaterial balance is the determination of the quantity ofnuclear material contained in inventories ofheterogeneous scrap. Segregation and identification ofvarious types and classes of such scrap can materiallyassist in the determination of the nuclear materialcontents by providing information necessary for theselection of appropriate measurement methods and forthe correction of measurement results for such things asimpurities, poisons, self-absorption, orself-multiplication. This guide describes acceptablestandard classifications for both plutonium and uranium"cold" scrap to aid in determining material balances.
B. DISCUSSION
Subcommittee Nl5.], of the American NationalStandards Institute (ANSI) Standards Committee NI5,Methods of Nuclear Materials Control, has developedtwo standards for the classification of "cold" scrapcontaining plutonium or uranium. The standard for theclassification of uranium scrap was approved by ANSI in1970. The standard for the classification of plutoniumscrap was approved by the ANSI Board of StandardsReview on July 25, 1972.
C. REGULATORY POSITION
The classifications for plutonium and uranium"cold" scrap contained in the following ANSI standardsare generally acceptable and are sufficiently flexible tobe applicable to a wide variety of nuclear facilities:ANSI N15.1-1970Classification of Unirradiated Uranium Scrap.1ANSI N15.10-1972Classification of Unirradiated PlutoniumScrap.Copies may be obtained from the American NationalStandards Institute, Inc., 1430 Broadway, New York, New York10018.USAEC REGULATORY GUIDES Copies of published guides may be obtained by request indicating the divisionsdesired to the US.
