1. REISSUANCE AND PURPOSE

This Directive reissues reference (a) to update policy, responsibilities, procedures, and minimum standards for safeguarding DoD nuclear reactors and special nuclear materials (SNM).

2. APPLICABILITY AND SCOPE

This Directive:

2.1. Applies to the Office of the Secretary of Defense (OSD); the Military Departments; the Chairman, Joint Chiefs of Staff and Joint Staff; the Unified and Specified Commands; the Defense Agencies having responsibility for the protection of nuclear reactors and SNM; and the DoD Field Activities (hereafter referred to collectively as "DoD Components").

2.2. Applies to all land-based nuclear reactors at fixed sites or in transit, research and test reactors under the direct control of DoD Components, and space-borne nuclear reactors located on DoD installations.

2.3. Applies to all SNM, regardless of form or whether incorporated in reactor cores or in other items under the direct control of DoD Components, except:

> 2.3.1. Self-protecting SNM; that is, SNM that are not readily separable from other radioactive material and that have a total external radiation dose rate in excess of 100 rems per hour at a distance of 3 feet from any accessible surface without intervening shielding. SNM in a single unit that weighs in excess of 5,000 pounds may have reduced security measures upon approval of the cognizant agency.

> 2.3.2. SNM in a quantity not exceeding 350 grams of uranium-235, plutonium, or combination possessed in any analytical, research, quality control, metallurgical, or electronic laboratory.

2.4. Does not apply to nuclear weapons. Because of the unique requirements associated with nuclear weapons, separate guidance regarding their security is provided in DoD Directive 5210.41 (reference (b)).

2.5. Does not apply to nuclear reactors or SNM on board U.S. Navy ships. (See paragraph 5.4.3., below.)

2.6. Does not apply to those nonactive or decommissioned DoD nuclear reactor facilities or nuclear propulsion systems on Navy ships when no fissile material is present.

2.7. Does not abrogate or abridge the:

> 2.7.1. Authority or responsibility of a commander to provide equivalent or better standards than those applied to licensed facilities or materials or to apply more stringent security standards required by other DoD Directives during emergencies, or at any time the threat to DoD nuclear reactors or SNM indicates additional protection measures are necessary.

> 2.7.2. Responsibility of DoD Components operating nuclear reactors under nuclear Regulatory Commission license or processing SNM to comply with the requirements of 10 CFR 73 (reference (c)), and DoE Orders 5632.2A and 5632.1A (references (d) and (e)).

PHYSICAL SECURITY STANDARDS FOR DoD NUCLEAR REACTORS AND CATEGORY I AND II QUANTITIES OF SPECIAL NUCLEAR MATERIAL

E4.1. INTRODUCTION

The standards outlined in this enclosure are provided to assist DoD Components in the development, design, and implementation of protective measures for nuclear reactors and SNM. The protective measures used for each location must be based on site-specific considerations and should address all of the areas in this enclosure.

E4.2. SECURITY SYSTEM CONCEPT

> E4.2.1. The goal of a security system for nuclear reactors and SNM is to apply efforts and resources in such a manner as to preclude radiological sabotage and the theft or diversion of SNM. To achieve this goal, a security system shall provide the capability to deter, detect, assess, delay, respond to, and neutralize the intended actions of the adversary.

> E4.2.2. The components of a security system each have a function and a related security objective. Together, the visible components should attempt to deter a potential adversary. Detection, accomplished through human or electronic measures, identifies possible threats and penetration attempts against the security system in sufficient time to allow the remaining portions of the security system to defeat the adversary. Assessment, through the use of closed-circuit television (CCTV) subsystems, patrols, and fixed personnel, assists in determining the size and intention of an intrusion. Delay, consisting of active and/or passive security measures using various barriers, provides sufficient time for the appropriate response to be made by the security force.

> E4.2.3. Response, consisting of security and law enforcement personnel, is provided to the target in such a manner as to prevent the adversary from accomplishing its goal. Response is accomplished by the use of specifically designated, trained, and properly equipped security forces. Neutralization, consisting of apprehending, forcing retreat, or eliminating the adversary, is the final objective.

E4.3. THREAT CONSIDERATIONS

> E4.3.1. The development of a security system is guided by a response to actual validated threats or to postulated threats that may arise. The threat is based on data derived from intelligence and investigative sources and may include overt activities or groups, either internal or external, using sophisticated equipment, arms, and methods. The intent of the threat may range from a person or group of persons demonstrating to make a political statement to persons desiring to obtain some SNM to fabricate a nuclear weapon or threaten the public with the potential of radiological contamination. The Defense Intelligence Agency (DIA) provides intelligence products that cover the range of threats mentioned above. In addition, the DIA is available to review plans for development of security systems for DoD nuclear reactors and SNM.

> E4.3.2. The minimum standards contained in this enclosure define what shall be required in designing a security system to protect nuclear reactors and SNM based on postulated threats. It is the responsibility of commanders at nuclear reactor and SNM facilities to define the local threat and to respond with commensurate measures.

E4.4. PHYSICAL SECURITY STANDARDS

Physical security measures for the protection of DoD nuclear reactors and SNM shall be accomplished in accordance with the following standards:

> E4.4.1. Physical Barriers

> > E4.4.1.1. Physical barriers consisting of fences, walls, and doors shall be designed to impede and aid in the detection of attempted entry and to provide sufficient delay to intrusion, thereby providing security response forces adequate time to apprehend and neutralize intruders.

> > E4.4.1.2. Physical barriers shall be designed to ensure a means of limiting ingress and egress of personnel and vehicles to a central point, thereby facilitating identification and control procedures.

> > E4.4.1.3. Physical barriers shall be used to define the perimeter of the Protected Area and Material Access or Exclusion Areas within the Protected Area. Both Exclusion Areas and Material Access Areas shall be located within the Protected Area so that access to vital equipment and SNM stored within these areas requires passage through at least two physical barriers.

> > E4.4.1.4. An illuminated clear zone shall be maintained adjacent to the physical barrier at the perimeter of the Protected Area and shall be large enough to permit unobstructed observation on either side of the barrier to detect activities and any penetration.

> > E4.4.1.5. A warning system, consisting of warning signs and a loudspeaker capability to warn intruders of the consequences of unauthorized entry, shall be established as an integral part of the physical barrier system.

> > E4.4.1.6. Guidance on construction techniques and materials for an effective physical barrier system is contained in MIL-HDBK-1013/1 (reference (j)).

> E4.4.2. Access Controls

> > E4.4.2.1. Material Access and Exclusion Areas shall be designed to positively identify and control all authorized individuals granted unescorted or escorted access to the nuclear reactor and SNM. All personnel without access authorization and their vehicles, packages, and material to be taken in or out of the Protected Area shall be identified, controlled, and searched. All personnel authorized access and their hand-carried packages shall be searched on at least a random basis. The access control system shall be designed to ensure prompt ingress and egress during emergency conditions and ensure access to vital equipment. Access control procedures shall be specified in the site security plan.

> > E4.4.2.2. Verification of identity shall be conducted by security personnel at area entrances using a numbered picture badge identification system for all personnel authorized access to the Protected Area without escort. Personnel not authorized entry to the Protected Area without escort shall be escorted and shall be badged to indicate that an escort is required. Additional levels of identification using other human, mechanical, or electronic means shall be used when dictated by an increased threat.

> > E4.4.2.3. The access control system shall be designed to prevent unauthorized entry of prohibited items, such as firearms, explosives, or incendiary devices, into areas containing SNM or a nuclear reactor. The system should also prevent the exit of SNM from areas containing Category II or greater quantities of SNM.

> > E4.4.2.4. Vehicle access to Protected Areas shall be restricted and controlled. All vehicles, except under emergency conditions, shall be searched for prohibited items before entry to the Protected Area. Emergency vehicles shall be kept under positive control by security forces while in the Protected Area and shall be searched before departing the area upon termination of the emergency.

> > E4.4.2.5. All keys, locks, combinations, and related equipment used to provide access to Protected, Material Access, Vital, and other restricted access areas shall be controlled to reduce probability of compromise.

> > E4.4.2.6. The Material Access, Exclusion, and Vital Areas shall be contained within the Protected Areas and their access controls shall be specified in the site security plan.

> E4.4.5. Lighting

> Adequate lighting shall be provided in clear zones and around other controlled access areas to discourage unauthorized entry, facilitate the detection of intruders, and assist in the identification of authorized personnel at entry control points during hours of darkness of reduced visibility. All security lighting shall have an auxiliary power source.

> E4.4.6. Security Force

> > E4.4.6.1. A security force shall be established to perform the physical security requirements outlined in this enclosure and enclosure E3., in the site security plan, and in applicable regulations.

> > E4.4.6.2. Members of the security force shall be trained, equipped, and qualified to perform each assigned security duty and to meet emergency situations. Sufficient security force members shall be readily available to react and respond to security alarms and incidents. (See DoD C-5210 41-M. (reference (p)) regarding force-on-force training exercises associated with security of Category I SNM.)

> > E4.4.6.3. Each facility shall have continuously on-site at least one full-time member of the security force with the authority and capability to direct physical protection activities and security response forces under emergency situations.

> > E4.4.6.4. Security force management shall provide for the development, implementation, and enforcement of security procedures. These procedures shall be continuously assessed and revisions made when required by changed conditions.

E5. ENCLOSURE 5

VARIANCES, WAIVERS, AND EXCEPTIONS

E5.1. GENERAL

Deviations from established security requirements shall be categorized as either a variance, waiver, or exception, and may be applicable to physical security facilities, plans, procedures, equipment, and monitoring standards established in this Directive or in any supplemental issuance.

> E5.1.1. A variance is the approved continuation of a nonstandard condition that technically varies from established requirements but essentially affords the same level of security.

> E5.1.2. A waiver is the approved temporary continuation of a nonstandard condition that deviates from an established security standard plus creates a security vulnerability to the security system and, therefore, requires compensatory measures. A waiver shall normally be approved for a period not to exceed 12 months and shall be extended only by the authority who granted the waiver and only after a review of the circumstances necessitating the extension.

> E5.1.3. An exception is the approved continuation of a nonstandard condition that varies from an established security standard plus creates a security vulnerability to the security system and, therefore, requires compensatory measures. Exceptions shall be granted only when correction of the nonstandard condition is adjudged to be not feasible or cost-effective. Exceptions shall be granted only after a careful and critical evaluation. All exceptions shall be reviewed by the granting authority at least every 2 years or when a major change in site configuration or mission offers the opportunity for corrective action to terminate the nonstandard condition. Exceptions shall be canceled unless it is found, by the approving authority, that the exception continues to be required and is justified.

E5.2. REVIEW OF REQUESTS

Waivers and exceptions shall be evaluated and approved by the commander of the Unified of Specified Command concerned (the respective heads of DoD Components for those sites not otherwise assigned to a Unified or Specified Command). This approving authority may be delegated in writing to a military officer of at least O-7 grade on the staff. When considering a deviation request for a particular facility or site, the approving authority shall review all other waivers and exceptions currently in effect for that facility or site. This review is to ensure that, collectively, the deviations will not establish an overall vulnerability greater than the designated compensatory measures. Each waiver or exception shall be evaluated and approved on a case-by-case basis. Blanket waivers or exceptions are not authorized. A 10 percent deviation from all measurable standards, such as clear zone distances, fence height, etc., is permitted; therefore, such deviation does not require the submission and/or approval of a waiver or exception request.

E5.3. COMPENSATORY MEASURES

> E5.3.1. A compensatory measure shall be instituted for each waiver or exception in effect. If appropriate, one compensatory measure may suffice for more than one waiver or exception. A compensatory measure shall also be instituted whenever two or more variances, taken together, are determined to constitute a vulnerability in the security system. For example, a fence that is a few inches below the required height does not by itself constitute a vulnerability; therefore, no compensatory measures are necessary. However, if there are additional variances at the facility or site; e.g., clear zones and perimeter lighting, which taken together are determined to create a vulnerability, then compensatory measures are required.

> E5.3.2. The approving authority shall review each waiver or exception to ensure that adequate compensatory measures have been established. Adequate compensatory measures may include additional security forces, procedures, and/or physical security devices such as additional locks, alarm, lighting, anti-intrusion devices, barricades, etc., which provide a level of security comparable to the required security standard. The criteria for accepting compensatory measures shall involve an assessment of the threat or vulnerability that has resulted from the condition that necessitates a waiver or exception. The compensatory measure shall be designed to specifically enhance the security posture in light of the deficient situation. Compensatory measures that consist primarily of instructions to the security force to increase their alertness do not provide a comparable level of security.
