Because of the sensitivity, access to NWD must be limited to those who have the appropriate clearance and a valid need-to-know to perform or assist in a lawful and authorized government function. A violation of the provisions of this Order relating to the safeguarding or security of Restricted Data or Formerly Restricted Data may result in a civil penalty pursuant to Section 234B of the Atomic Energy Act of 1954 (42 U.S.C. 2282b). The procedures for the assessment of civil penalties are set forth in Title 10, Code of Federal Regulations (CFR), Part 824, “Procedural Rules for the Assessment of Civil Penalties for Classified Information Security Violations.” The DOE (including NNSA) is responsible for establishing policy concerning the control and dissemination of Restricted Data (RD) and, jointly with the Department of Defense (DoD), Formerly Restricted Data (FRD) to ensure the common defense and security. This Order pertains to the access, control and dissemination of RD and FRD only in the atomic weapons program herein referred to as NWD. DOE O 452.8 3 7-21-2011 a. This Order uses DOE M 470.4-1, Chg 2, Safeguards and Security Program Planning and Management, dated 10-20-10; DOE O 471.6, Information Security, dated 6-20-11; and NNSA Policy Letter NAP 70.4, Information Security, dated 7- 2-10, as baseline requirements for the protection of classified information. This Order specifies additional requirements for the protection and security of NWD. Notify NNSA Office of Nuclear Weapon Surety and Quality of any conflicts between this Order and the DOE Manuals or the NNSA NAPs. The Office of Nuclear Weapon Surety and Quality will continue to work closely with the DOE Office of Health, Safety, and Security (DOE/HSS) and the NNSA Office of Defense Nuclear Security in the establishment of policies and procedures that protect and control NWD. b. NWD Sigma categories were established to provide additional need-to-know protection of specific types of NWD. This Order provides for: (1) Disestablishment of obsolete NWD categories formerly known as Sigmas 1-5 and Sigmas 9-13. (a) Appendix A, Control of Nuclear Weapon Data, provides the framework for the protection of NWD. (b) Appendix C, Obsolete NWD Categories, provides historical information on the NWD Sigma categories disestablished by this Order. (2) Establishment of a new NWD category known as Sigma 18, Control of Complete Designs, that provides protection of past and present U.S. nuclear weapons, nuclear devices and weapon designs. Appendix B, Control of Complete Designs, provides details for the protection of Sigma 18 NWD. (3) Sustainment of Sigma 14 and Sigma 15, Protection of Use Control Vulnerabilities and Designs and Sigma 20, Improvised Nuclear Device Information. (a) Specific details on the management of Sigma 14 and Sigma 15 NWD are found in DOE O 452.7, Protection of Use Control Vulnerabilities and Designs, dated 5-14-10.

PONEMAN Deputy Secretary DOE O 452.8 Appendix A 7-21-2011 A-1 APPENDIX A CONTROL OF NUCLEAR WEAPON DATA 1. IDENTIFICATION OF NUCLEAR WEAPON DATA (NWD). a. NWD is Restricted Data or Formerly Restricted Data concerning the design, manufacture, or utilization (including theory, development, storage, characteristics, performance and effects) of nuclear explosives, nuclear weapons or nuclear weapon components, including information incorporated in or related to nuclear explosive devices. NWD is matter in any combination of documents or material, regardless of physical form or characteristics. b. NWD may be categorized as Sigma 14, Sigma 15, Sigma 18 or Sigma 20. (1) Specific details on the management of Sigma 14 and Sigma 15 NWD are found in DOE O 452.7, Protection of Use Control Vulnerabilities and Designs, dated 5-14-10. (2) Specific details on the management of Sigma 18 NWD are found in Appendix B, Control of Complete Designs. (3) Specific details on the management of Sigma 20 NWD are found in DOE O 457.1, Nuclear Counterterrorism, dated 2-7-06, and DOE M 457.1-1, Control of Improvised Nuclear Device Information, dated 8-10-06. c. Not all NWD requires the additional protection of a Sigma category. NWD that is not in a Sigma category is referred to as Non-Sigma NWD. Specific details on the management of Non-Sigma NWD is found in this Appendix. d. Newly created NWD or existing NWD that has had the content modified must be

reviewed. If the NWD is determined to contain Sigma 14, Sigma 15, Sigma 18 or Sigma 20, it must be appropriately marked. e. Unmodified legacy NWD with obsolete Sigma markings does not require review or remarking when accessed 2. ACCESS REQUIREMENTS. a. See Table A-1 below for clearance and access requirements. In addition to the clearance requirements, access to NWD must be restricted to personnel with valid need-to know and confirmed Sigma access authorization as appropriate. b. Foreign Nationals may be granted access to NWD only as permitted under the Atomic Energy Act of 1954, as amended (AEA), including agreements for cooperation concluded in accordance with AEA section 123. c. The NNSA NWD Program Coordinator will provide guidance on the appropriate background investigation required for each clearance.. Appendix A DOE O 452.8 A-2 7-21-2011 d.

It is the sender’s responsibility to contact their Safeguards and Security Information Management System (SSIMS) Coordinator to ensure that one is initiated or already in place prior to sending the matter. The SSIMS Coordinator will confirm the site is authorized to receive NWD through SSIMS. If a SSA is not in place, one must be initiated and processed using the procedures outlined in DOE M 470.4-1, Chg. 1. (a) For SSAs not based on a contract, an unclassified justification must be provided detailing the facility’s need to receive and store NWD. (b) Each SSA must be submitted to the Office of Nuclear Weapon Surety and Quality 30-days prior to the required establishment or renewal date. (c) Each SSA must be properly certified. 1 DoD SSAs must be properly certified by an authorized official from the most recent Enclosure 5 of the DoD Directive 5210.2. A copy can be obtained directly from the Office of the Deputy Assistant to the Secretary of Defense (Nuclear Matters). DOE O 452.8 Appendix A 7-21-2011 A-5 2 SSAs from OGAs must be properly certified by their Cognizant Security Official.

(d) Approved SSA’s will be authorized for three years or for the length of the contract, whichever is less. (e) The Designated Responsible Office (DRO) will be responsible for renewal submissions. Sigma authorizations must be immediately removed from SSIMS for expired SSAs that did not have renewals submitted 30-days prior to expiration. g. Electronic Transmission.

RESTRICTED DATA This document contains Restricted Data as defined in the Atomic Energy Act of 1954. Unauthorized disclosure is subject to Administrative and Criminal Sanctions. DOE O 452.8 Appendix B 7-21-2011 B-1 APPENDIX B CONTROL OF COMPLETE DESIGNS 1. IDENTIFICATION OF SIGMA 18 NUCLEAR WEAPON DATA (NWD). a. Complete Designs are the compilation of design information revealing materials, masses, dimensions, contours and specifications in sufficient detail to enable a nuclear weapon to be copied or constructed. b. Sigma 18 information would allow or significantly facilitate a proliferant nation

or entity to fabricate a credible nuclear weapon or nuclear explosive based on a proven, certified, or endorsed U.S. nuclear weapon or device. The information would enable the establishment or improvement of nuclear capability without nuclear testing or with minimal research and development. Based on this description, NNSA has determined that Complete Designs are Sigma 18. c. Newly created NWD or existing NWD that has had the content modified must be reviewed. If the NWD is determined to contain Sigma 18, it must be appropriately marked. 2. ACCESS REQUIREMENTS. a. See Table B-1 below for clearance and access requirements for Sigma 18. In addition to the clearance requirements, access to Sigma 18 must be restricted to personnel with a valid need-to-know. b.
