CHAPTER IV

                       CLASSIFICATION CRITERIA AND LEVELS

                      PART A - CRITERIA FOR CLASSIFICATION

1.  RESTRICTED DATA AND FORMERLY RESTRICTED DATA.  Information under the
    purview of the Atomic Energy Act is classified at its inception by that
    Act.  There is no original determination required to classify such
    information because all RD and FRD is originally classified by the Act.

2.  NATIONAL SECURITY INFORMATION.

    a.   Criteria for Classification.  The following two conditions must be
         met before official information may be classified pursuant to
         Executive Order 12356:

         (1)  The information must concern at least one of the following
              areas:

              (a)  Military plans, weapons, or operations;

              (b)  Vulnerabilities or capabilities of systems,
                   installations, projects, or plans relating to the
                   national security;

              (c)  Foreign government information;

              (d)  Intelligence activities (including special activities) or
                   intelligence sources or methods;

              (e)  Foreign relations or foreign activities of the United
                   States;

              (f)  Scientific, technological, or economic matters relating
                   to the national security;

              (g)  U.S. Government programs for safeguarding nuclear
                   materials or facilities;

              (h)  Cryptology;

              (i)  A confidential source; or

              (j)  Other categories of information related to the national
                   security that require protection against unauthorized
                   disclosure, as determined by the President, the
                   Secretary, or SA-1.  Any determination made under this
                   subsection shall be reported promptly to the Director of
                   ISOO by SA-20.

         (2)  The unauthorized disclosure of the information itself or in
              the context of other information could reasonably be expected
              to cause damage to the national security.  (Note: Unauthorized
              disclosure of foreign government information, the identity of
              a confidential foreign source, or intelligence sources or
              methods is presumed by Executive Order 12356 to cause damage
              to the national security.)

    b.   Unofficial Publication or Inadvertent or Unauthorized Disclosure.
         Information classified in accordance with the above shall not be
         declassified automatically as a result of any unofficial
         publication or inadvertent or unauthorized disclosure in the United
         States or abroad of identical or similar information.
