U.S. Department of Energy ORDER
Washington, D.C. DOE 5610.2
Chg 1: 9/2/86
SUBJECT: CONTROL OF WEAPON DATA
1. PURPOSE. This Order establishes the procedures for the control of
2. SCOPE. The provisions of this Order apply to all elements of the
Department of Energy (DOE) and all contractors and subcontractors
performing work for the Department, who have or may have weapon data
under their custody or control.
3. SPECIAL INSTRUCTIONS. This Order replaces Manual Chapter and Appendix
2108, WEAPON DATA, which was canceled 10-1-77.
4. GENERAL. It is necessary to differentiate between the handling of
weapon data and other specialized or technical data because of its
direct relationship to our nation's defense. The provisions of the
Atomic Energy Act stipulate the control and dissemination of Restricted
Data to assure the common defense and security. Weapon data is always
Restricted Data, or Formerly Restricted Data, specifically that portion
concerning the design, manufacture, or utilization of atomic weapons.
a. Critical Nuclear Weapon Design Information (CNWDI). A Department of
Defense (DOD) category of weapon data designating Top Secret/
Restricted Data or Secret/Restricted Data revealing the theory of
operation or design of the components of a thermonuclear or fission
bomb, warhead, demolition munitions, or test device. Specifically
excluded from designations as CNWDI is information concerning:
(1) Arming, fuzing, and firing systems.
(2) Limited life components.
(3) Total contained quantities of fissionable, fusionable, and high
explosive materials by type.
(4) Components which military personnel set, maintain, operate,
test, or replace.
b. Defense Technical Information Center (DTIC). The central facility
of the DOD for secondary distribution of technical reports generated
by research, development, test, and evaluation efforts sponsored by
the Department of Defense.
c. Document. Any recorded data, regardless of the form, not limited
to, but including:
(1) Handwritten, printed, or typed.
(2) Painted, drawn, or engraved.
(3) Magnetically or electromagnetically recorded.
(4) On paper, plastic, or metal tapes, punched cards, or aperture
(5) Contained on exposed film, or in photographs.
(6) Any reproduction of the foregoing.
d. Field of Interest Register. A method used by the Department of
Defense to authorize automatic distribution of documents from the
Defense Technical Information Center. Access is controlled by
subject category and by classification level.
e. Formerly Restricted Data. Classified information jointly determined
by DOE and DOD to be related primarily to the utilization of atomic
weapons, and removed by DOE from the Restricted Data category
pursuant to section 142(d) of the Atomic Energy Act.
f. Production Rate or Stockpile Quantity Information. Classified data
related to production rates of weapons or weapon components or to
stockpile quantities of weapons or weapon components.
g. Restricted Data. That data which is defined in sectionally of the
Atomic Energy Act of 1954, as amended, as "all data concerning (1)
design, manufacture, or utilization of atomic weapons; (2) the
production of special nuclear material; or (3) the use of special
nuclear material in the production of energy, but shall not include
data declassified or removed from the Restricted Data category
pursuant to section 142."
h. Sigma Categories. Restricted Data and/or Formerly Restricted Data
in the following categories which concern the design, manufacture,
or utilization of atomic weapons, or utilization of atomic weapons
or nuclear explosive devices. (See Weapon Data defined on page 4,
(1) Sigma 1. Theory of operation (hydrodynamic and nuclear) or
complete design of thermonuclear weapons or their unique
(2) Sigma 2. Theory of operation or complete design of fission
weapons or their unique components. This includes the high
explosive system with its detonators and firing unit, pit
system, and nuclear initiation system as they pertain to weapon
design and theory.
(3) Sigma 3. Manufacturing and utilization information not
comprehensively revealing the theory of operation or design of
the physics package. Complete design and operation of
nonnuclear components but only information as prescribed below
for nuclear components. Utilization information necessary to
support the stockpile to target sequence. Information
(a) General external weapon configuration, including size,
weight, and shape.
(b) Environmental behavior, fuzing, ballistics, yields, and
(c) Nuclear components or subassemblies which do not reveal
theory of operation or significant design features.
(d) Production and manufacturing techniques relating to
nuclear components or subassemblies.
(e) Anticipated and actual strike operations.
(4) Sigma 4. Information inherent in preshot and postshot
activities necessary in the testing of atomic weapons or
devices. Specifically excluded are the theory of operation and
the design of such items. Information includes:
(a) Logistics, administration, other agency participation.
(b) Special construction and equipment.
Note: Sigma 1 and Sigma 2 generally, but not completely, equate to
the CNWDI defined on page 1, subparagraph a.
(c) Effects, safety.
(d) Purpose of tests, general nature of nuclear explosive
tested including expected or actual yields and conclusions
derived from tests not to include design features.

which reveals or is indicative of weapon data.
(9) Sigma 12. Complete theory of operation, complete design, or
partial design information revealing either sensitive design
features or how the energy conversion takes place for the
nuclear energy converter, energy director or other nuclear
directed energy weapon systems or components outside the
envelope of the nuclear source but within the envelope of the
nuclear directed energy weapon.
Note: Theory of operation or complete design information for a
nuclear directed energy weapon requires access to Sigmas 1,
2, and 12 information. Cleared persons not requiring
access to Sigmas 1, 2, or 12 information will normally be
granted Sigmas 3 and 13, as appropriate.
(10) Sigma 13. Manufacturing and utilization information and output
characteristics for nuclear energy converters, directors or
other nuclear directed energy weapon systems or components
outside the envelope of the nuclear source, not comprehensively

the nuclear directed energy weapon or how the energy conversion
takes place. Information includes:
(a) General, external weapon configuration and weapon
environmental behavior characteristics, yields, and
(b) Component or subassembly design that does not reveal
theory of operation or sensitive design features of
nuclear directed energy weapons categorized as Sigmas 1,
2, or 12.
(c) Production and manufacturing techniques for components or
subassemblies of nuclear directed energy weapons that do
not reveal information categorized as Sigmas 1, 2, or 12.
i. Transfer and Accountability Station. An organizational unit which
controls the receipt, transmission, accountability, and disposition
of classified reports.
j. Weapon Data. Restricted Data/Formerly Restricted Data concerning
the design, manufacture, or utilization (including theory,
