A. INTRODUCTION

Methods of Nuclear Materials Control, has developed two standards for the classification of "cold" scrap Part 70 of the Atomic Energy Commission's containing plutonium or uranium. The standard for the regulations requires each licensee to maintain material classification of uranium scrap was approved by ANSI in control and accounting procedures for the special 1970. The standard for the classification of plutonium nuclear material in his possession under license.
