of sensitive improvised nuclear device (IND) information.
b. To support the implementation of high-level policy guidance for protecting the
homeland against nuclear terrorism as outlined in the National Strategy for
Combating Terrorism and the National Strategy for Homeland Security.
c. To establish DOE responsibilities for identifying and protecting sensitive IND
information.
d. To establish controls on the dissemination of sensitive IND information.

eliminate requirements no longer applicable or substitute a new set of
requirements.
3. APPLICABILITY.

CONTRACTOR REQUIREMENTS DOCUMENT
DOE O 457.1A, NUCLEAR COUNTERTERRORISM
1. Regardless of the performer of the work, the contractor is responsible for complying
with the requirements of this CRD and Appendix B, and flowing down CRD
requirements to subcontractors at any tier to the extent necessary to ensure contractor
compliance. Appendices A and B are “Official Use Only” and may be obtained by
contacting the Director, Office of Nuclear Threat Science.
2. This CRD establishes the requirements for DOE contractors whose contracts
involve or could potentially involve accessing or generating nuclear weapon
design information.
3. Contractors are required to protect IND information. To this end, contractors
designated to conduct IND and Sigma 20 activities will implement a Sigma 20
NWD control category to control the dissemination of sensitive IND information in
the interest of U.S. national security. Procedures will be implemented to provide for
strict control of and access to Sigma 20 NWD. IND design-related work is not to be
conducted at any DOE location unless authorized by the Associate Administrator for
Nuclear Counterterrorism and Counterproliferation. In this context, IND
design-related work includes generating:
a. any complete design of an IND, including speculative exploration of
novel design concepts;
b. validation of comparative assessments of IND design alternatives;
c. descriptions of design and fabrication procedures likely to be employed by
terrorists, including modeling or design methodologies, energetic or nuclear
material specifications, component specifications (e.g., arming and firing
system design), or other fabrication procedures; and
d. realistic IND designs to assess the performance of radiation detection
systems, diagnostic equipment, security standards, and/or render-safe tools
and procedures.
Section 6
4. Contractors must support annual program reviews, when and as directed by the
Director, Office of Nuclear Threat Science, to evaluate relevant ongoing activities;
future plans and projects; resource requirements, including the resources necessary
to implement and administer this Order; and major concerns and issues.
5. Contractors must maintain records according to National Archives and Records
Administration-approved DOE or site-specific records retention schedules.
