INTRODUCTION  Part 73, Physical Protection of Plants and Materials, of Title  10, Code of Federal Regulations, specifies performance requirements for  the physical protection of special nuclear materials and associated  facilities. Section 73.20, General Performance Requirements,  describes the general performance objective and requirements that must  be met through the establishment of a physical protection system.  Performance capabilities necessary to meet the requirements of Section  73.20 are described in Section 73.45, Performance Capabilities for  Fixed Site Physical Protection Systems. While detection and control  requirements are specified throughout the capability statements,  specific entry/exit control techniques are required under three  capabilities. Paragraph 73.45(b) specifies preventing unauthorized  access of persons, vehicles and materials into material access areas and  vital areas. A physical protection system must achieve this by using  entry controls, among other things. Paragraph 73.45(e) permits removal  of only authorized and confirmed forms and amounts of strategic special  nuclear material from material access areas. The system must achieve  this capability by providing detection subsystems and procedures to  detect, assess, and communicate attempts at unauthorized removal.  Paragraph 73.45(f) provides for ensuring only authorized access to the  protected area and requires, in part, the use of entry controls to meet  the capabi
