    DIRECTORATE OF REGULATORY STANDARDS
    REGULATORY GUIDE 5.7
    CONTROL OF PERSONNEL ACCESS TO PROTECTED AREAS,
    VITAL AREAS, AND MATERIAL ACCESS AREAS
A. INTRODUCTION
    Proposed amendments to the Commission regulations of 10 CFR Part
    50, "Licensing of Production and Utilization Facilities," 10 CFR Part
    70, "Special Nuclear Material," and 10 CFR Part 73, "Physical Protection
    of Special Nuclear Material," would, if adopted, require measures (1)
    for the protection against industrial sabotage of fuel reprocessing
    plants and certain facilities subject to the provisions of 10 CFR Part
    70 and (2) for the protection of special nuclear material (SNM) against
    theft or diversion from certain licensed facilities.
    One element of this protection is proper control of access of
    personnel to and from protected areas, vital areas, and material access
    areas. Searching persons and packages for firearms, explosives, and
    other devices which could aid in sabotage or theft of SNM is another
    element of physical protection.
    This guide describes acceptable methods of searching personnel
    prior to entry into a protected area and upon exit from a material
    access area, and of controlling access to protected areas, vital areas,
    and material access areas.
B. DISCUSSION
    The objective of controlling access to protected areas, vital
    areas, and material access areas is to ensure that (1) only persons
    authorized access to a protected area are permitted within that area and
    (2) that only individuals authorized access to vital equipment or
    special nuclear material will be allowed within vital areas or material
    access areas.
    The objective of searching individuals prior to permitting entry
    into a protected area is to prevent illicit passage into the protected
    area of objects such as firearms, explosives, and incendiary devices
    which could aid in industrial sabotage to the facility or in the theft
    of special nuclear material. Searching individuals and packages for
    concealed special nuclear material at exit points from material access
    areas provides a means of detecting attempted theft or diversion of
    special nuclear material.
    Some means by which control of access can be accomplished include
    a key and lock system, a magnetic or electronic key-card system, an
    attendant guard or watchman, or a closed-circuit TV (CCTV) in
    conjunction with keys or key-cards. Of these means, the magnetic or
    electronic key-card system in conjunction with closed-circuit TV offers
    the greatest security with a minimum of personnel. The key-cards are
    much more difficult to duplicate than keys and the locks cannot be
    "picked." Further, the control system can "read" the key-card and record
    the identity of the card (to whom it was issued) and the time of entry.
    A closed-circuit TV system would allow visual observation of the access
    point without requiring an attendant guard or watchman. In fact, by use
    of closed-circuit TV several such access points can be maintained under
    observation by a single guard or watchman. Such a system would be
    especially useful at access points to remote or normally unoccupied
    vital areas or material access areas. In any case, visual observation,
    either directly or via CCTV, provides a positive means of assuring that
    only individuals authorized access to an area pass through the access
    point into the area.
    Searching of individuals can be carried out by means of a hands-on
    search ("frisking"), or by means of devices which will detect the
    presence of weapons and explosives or SNM concealed on the individual,
    or by a combination of both. The search should be conducted in a manner
    which (1) provides assurance that firearms, explosives, and other such
    contraband are not being carried into the protected area and that SNM is
    not being transported out of a material access area and (2) minimizes
    inconvenience to the individuals being searched. The use of equipment
    capable of detecting weapons, explosives, or SNM is usually the
    preferable form of searching, since the use of detection devices avoids
    the personal imposition of a hands-on search.
    An "airport type" weapon (metal) detector located in a passageway
    arranged so that all individuals entering the protected area pass
    through the detector provides a convenient and effective means of
    searching for firearms.
    Devices capable of detecting dynamite, TNT, and other explosives
    can be used to search individuals for concealed explosives. Most
    explosive detectors commercially available at present are of the
    hand-held "sniffer" variety; hence an attendant guard or watchman must
    pass the detector over the individual being searched. However, it is
    possible to locate an explosive detector in a passageway and to use the
    detector in the same manner that a fixed weapon detector is used.
    If a hand-held explosive detector is used, the explosive check is
    best made after the weapon detector has indicated that no weapon is
    concealed upon the individual. This procedure affords greater
    protection to the attendant guard or watchman on the presumption that
    concealed explosives offer less of an immediate danger to the guard or
    watchman than a concealed firearm.
    One alternative approach to the hand-held explosive detector would
    be the location of an explosive detector within a revolving-door frame.
    The rather small volume of air trapped in a section of the revolving
    door would be sampled by the explosive detector and, as the isolation of
    the air volume by a revolving door section provides some concentration
    of vapors emitted by any explosives within that section, the
    effectiveness of the detector would be increased. To further increase
    efficiency of the explosive detector, the air in the door section might
    be flushed through the detector.
    Searching individuals for concealed SNM upon exit from material
    access areas can be accomplished in a variety of ways. For example, at
    facilities processing plutonium or uranium-233 the search for concealed
    SNM can be made in an attended air lock between change rooms. At areas
    where only highly enriched uranium is processed, the search can be
    carried out by use of a doorway SNM monitor and a metal detector in
    conjunction with a closed-circuit TV (CCTV) system, hence a guard or
    watchman need not be attendant. However, whether or not the access point
    is attended, the use of both an SNM monitor and a metal detector would
    seen necessary to assure that enriched uranium, shielded or unshielded,
    is not being concealed. In addition, exit from any material access area
    should be controlled to assure that all individuals and packages exiting
    from a material access area pass through the SNM check system.
    It is the facility guards and watchmen who are charged with the
    responsibility of assuring that firearms, explosives, and other similar
    items or devices are not transported into the protected area and that
    SNM is not removed from a material access area without authorization.
    Hence, they should search any packages being carried into the protected
    area or out of a material access area. No individual should be allowed
    to directly hand carry any package, valise, tool box, or similar
    hand-carriable item into the protected area or out of a material access
    area. Such objects should be handed to an attendant guard or watchman
    who will check them and pass them into the protected area or out of the
    material access area. To further reduce the possibility of concealment,
    where feasible, bulky outer clothing such as overcoats, raincoats,
    greatcoats, and ski jackets should be left in a cloak room provided
    outside the protected area and in any case should never be taken into a
    material access area. The licensee may wish to use several members of
    the security force to check packages, coats, etc., during shift change
    to minimize the delay encountered in gaining access. Unattended access
    points into the protected area can be used, provided observation of such
    points is maintained by CCTV to assure that packages are not being hand
    carried into the protected area at that point.
    Posting of a sign in a conspicuous location will inform
    individuals requesting access into the protected area that they will be
    searched, and that any packages, etc., they wish to take into the
    protected area will also be searched.
    Although the Commission regulations do not require searching of
    individuals entering a material access area, observation of access
    points provides a convenient method of ensuring that personnel do not
    carry weapons, explosives, and other similar items or devices into the
    material access area.
    In emergency situations, such as those which may require the
    evacuation of a material access area, the objectives of access control
    and search should not be allowed to compromise health and safety.
    Hence, the licensee should develop plans of action and provide areas and
    equipment for searching and controlling access under emergency
    conditions compatible with the objectives of both safety and security.
    Such emergency procedures will minimize the effectiveness of an
    emergency situation deliberately perpetrated to conceal theft of SNM.
    Administrative controls, as well as physical barriers where
    applicable, may be employed to gather evacuating individuals within a
    holding area. Such controls would serve both to verify that no one has
    remained in the evacuated area and to ensure that an emergency situation
    will not successfully conceal an attempted theft of SNM.
C. DEFINITIONS
    For the purpose of this guide the following definitions are
    provided:
1. "Guard" means an armed and uniformed individual whose primary duty
    is the protection of materials and property to the extent that theft of
    SNM or sabotage of the facility could pose a threat to the common
    defense and security or result in a radiological hazard to public health
    and safety.
2. "Watchman" means an unarmed individual, not necessarily uniformed,
    who provides protection for materials and property in the course of
    performing other duties.
3. "Patrol watchman" means an arms-qualified individual whose primary
    duty, at least during threat or emergency situations, is the protection
    of material and property, and who is normally unarmed but who may be
    armed during emergency or threat situations. A patrol watchman may or
    may not be uniformed.
D. REGULATORY POSITION
1. Protected Areas
    a. Identity and Authorization
    At each access point into a protected area, an identity and
    access authorization check should be made in conjunction with a search
    for firearms and explosives. Such identity and access authorization
    checks should be performed by an attendant guard or watchman or by means
    of an electronic or magnetic key-card system and a closed-circuit TV
    system. Packages should be taken into the protected area only at access
    points attended by a guard or watchman. If the access point is
    unattended, the individual monitoring the access point via
    closed-circuit TV should carefully observe any individual requesting
    access at that point to ensure that no packages are being carried into
    the protected area.
    b. Personnel Search
    If the search of individuals is to be carried out by means
    of detection equipment, a weapon (metal) detector and an explosive
    detector should be used. An acceptable arrangement for the use of
    detection equipment in a secure access passageway is illustrated in
    Figure 1. The doors on the secure access passageway should be
    interlocked so that both cannot be simultaneously open, thus providing
    positive access control. An explicit enabling act should be required of
    a security individual, either attending the secure access passageway or
    in the central alarm station, to open the inner door.
    c. Metal Detector
    The metal detector located within the secure access
    passageway should be capable of detecting a minimum of 200 grams of
    non-ferrous metal placed anywhere on the body at a 90% confidence limit.
    The false alarm rate should be a maximum of 1%.
    d. Explosive Detector
    The explosive detector, as a minimum, hould be capable of
    detecting dynamite, TNT, and similar nitrogen compounds in minimum
    amounts of 200 grams at a 90% confidence limit. The false alarm rate
    should be a maximum of 1%. If detector is hand held rather than
    permanently fixed to a passageway or revolving door frame, hence
    requiring an attendant guard or watchman, the search for explosives
    should be performed after the search for firearms. An acceptable
    arrangement is illustrated in Figure 2.
    e. Alarm Annunciation
    The alarms of the weapon detector and the explosive detector
    should annunciate at the location of the detectors, if attended, as well
    as in a central alarm station. The alarm annunciation at the location
    of the detectors need not be aural.
    f. Alarm System
    The alarms of the weapon (metal) detector and the explosive
    detector should be interfaced with the inner door lock so that, with an
    alarm triggered, the inner door cannot be opened from either side
    without a specific action by the individual manning the central alarm
    station acknowledging the alarm and enabling the inner door to be
    opened.
2. Material Access Areas Containing Pu or U-233
    a. Change Room Exit
    Checking for concealed plutonium or uranium-233 at an exit
    point from a material access area into a protected area should be
    performed in an attended secure access passageway located between change
    rooms. An acceptable arrangement is shown in Figure 3. Unless exit is
    into a contiguous material access area, all individuals should exit from
    a material access area, other than a vault, only via the change rooms
    and should be required to deposit all work clothing in the inner change
    room, walk through the passageway, and dress in street clothing in the
    outer change room. The licensee should generally not allow packages to
    be transported out of the material access area via the change rooms.
    Showers, except those used exclusively for health physics, should be
    located in the outer change room. A guard or watchman need not be
    attendant except when personnel are exiting from the material access
    area.
    b. SNM Detector
    An SNM detector should be located within the passageway.
    The detector should be capable of detecting 0.5 gram of plutonium or 1
    gram of uranium-233 shielded by 3 mm of brass concealed anywhere on an
    individual at a 90% confidence limit. The false alarm rate on the
    detector should be less than 0.1%.
    c. Door Interlock
    The doors of the attended secure access passageway should be
    interlocked so that both cannot be simultaneously open. The doors
    should also be alarmed so that an explicit action must be taken by
    either the attendant security individual or the individual manning the
    central alarm station to enable either door to open without triggering
    the alarm.
    d. Packages
    All packages, including waste barrels and work clothes
    hampers, being transported out of a material access area should be
    checked by an attendant guard or watchman for concealed SNM, preferably
    at an exit point expressly provided for packages. SNM packages should
    be checked for proper seals, identification, and transfer documentation.
    e. Change Room Access
    Access by personnel into a material access area should be
    permitted only through the change rooms. Control of access should be
    accomplished either by a guard or watchman attending the secure access
    passageway between the change rooms, or by a combination of key-card and
    CCTV when the passageway is unattended.
    f. Observation of Individuals
    Procedures should be employed in the control of access to
    material access areas to ensure that no lone individual is allowed
    within a material access area without some means to observe that
    individual's activities.
3. Material Access Areas Containing Highly Enriched Uranium, and
    Vaults Containing SNM
    a. Exit
    At material access area exit points, the check for concealed
    SNM should be carried out by means of an SNM doorway monitor and a metal
    detector. A secure access passageway located at the exit point from the
    material access area should house the detection equipment. An attendant
    guard or watchman or a closed-circuit TV connected to the central alarm
    station should also be provided. Administrative procedures should
    require the passage of packages only through attended exit points. The
    doors of the secure access passageway should be interlocked so that both
    cannot be simultaneously open. A suggested layout is illustrated in
    Figure 4.
    b. SNM Detector
    The SNM doorway monitor in the secure access passageway
    should be capable of detecting a minimum of 3 grams uranium enriched to
    90% in the uranium-235 isotope in 3 mm of brass concealed anywhere on an
    individual at a 50% confidence limit. The false alarm rate should not
    exceed 0.1%.
    c. Metal Detector
    The metal detector in the secure access passageway should be
    capable of detecting a minimum of 100 grams of non-ferrous metal
    (shielding) at a 90% confidence limit concealed anywhere on an
    individual. The false alarm rate should not exceed 0.1%.
    d. Alarms
    The doors of the secure access passageway should be alarmed
    and interfaced with the doorway monitor such that an individual can be
    detained for a sufficient time for the doorway monitor to operate. If
    an individual passes through without waiting for the proper period of
    time (perhaps indicated by a light) the alarm should sound. The doorway
    monitor and metal detector alarms and the door alarms should annunciate
    in the central alarm station and may also annunciate at the passageway.
    e. Access
    The exit points from the material access area should be used
    for access points as well. Control of access should be by either the
    attendant security individual or by a key-card CCTV system.
    f. Closed-Circuit TV Observation
    If observation of the passageway is accomplished by CCTV,
    the guard or watchman monitoring the passageway should carefully observe
    any individual within to ensure that no packages are being carried into
    or out of the access area.
    g. Observation of Individuals
    Procedures should be employed in the control of access to
    material access areas to ensure that no lone individual is allowed
    within a material access area without some means to observe that
    individual's activities.
    h. Vaults
    A key-card CCTV system should be employed to control access
    to and from a vault if such access and exit points do not open to or
    from material access areas contiguous to the vault. In addition, all
    individuals who transport SNM between material access areas or to or
    from a vault, should be escorted by a member of the facility's security
    force during any period of the transport that the SNM is not within a
    material access area.
4. Vital Areas
    Control of access into vital areas should be accomplished either
    by an attendant guard or watchman, or by means of magnetic or electronic
    key-card access in conjunction with closed-circuit TV. The
    identification check should include either direct observation by an
    attendant guard or watchman or observation by CCTV of each individual
    passing into the vital area, or some alternate means (e.g., an escort)
    which will provide positive assurance that only individuals authorized
    access to the vital area are permitted to pass into that area.
5. Security Force Response to an Alarm
    The guards and patrol watchmen should be trained and prepared to
    protect the facility from sabotage and the SNM within from theft.
    a. Protected Area Access Point
    Upon annunciation of an alarm from explosive or weapon
    detection equipment located at a protected area access point attended by
    a lone guard or watchman, a guard should be dispatched immediately to
    the access point originating the alarm. If the access point is
    unattended, two guards should be sent to the access point. At the
    access point the guard or watchman should request that the individual's
    pockets be emptied and that the individual pass again through the
    detection equipment. If the individual complies and if the alarms do
    not register, the individual may be allowed to pass into the protected
    area after the contents of the individual's pockets have been examined
    verifying that no attempt has been made to pass explosives or firearms
    into the protected area. If, however, an alarm continues to register,
    the individual should be physically searched by an unarmed security
    individual, while at least one guard or armed patrol watchman observes,
    to verify that no firearms or explosives are yet concealed by the
    individual. If the individual refuses to comply with the request for
    further searching, or if a weapon or explosives are found, the
    individual should be denied access.
    b. Material Access Area Exit Point
    If an SNM or metal detector alarm or a door alarm is
    triggered at a material access area exit point attended by a guard or
    watchman or at an unattended exit point, security personnel, at least
    one of whom is armed (a guard or armed patrol watchman), should be
    dispatched to that exit point. The individual should be searched by
    emptying pockets and passing again through the detection equipment or by
    a hands-on search performed by an unarmed security individual while at
    least one guard or armed patrol watchman observes. The cause of the
    alarm should be determined before the individual is released. If the
    cause of the alarm was an object, metal or SNM, not concealed by the
    individual, the individual should be searched without the object to
    ensure that the object is not a decoy and that SNM is not still being
    concealed by the individual. If the security personnel determine that
    attempted unauthorized removal of SNM has been made with the intent to
    steal SNM, local police and the Federal Bureau of Investigation should
    be contacted, and the individual should be held by the security
    personnel until the local police arrive and arrest the individual.
    c. Unoccupied Vital Areas and Material Access Areas
    If unauthorized entry is made or attempted into a vital area
    or material access area, or if an intrusion alarm protecting an
    unoccupied vital or material access area is triggered, two armed
    security personnel should be dispatched immediately to the area of
    alarm. If, however, the area of the alarm can be observed by CCTV, the
    guard or watchman in the alarm station where the TV monitor is located
    should first verify the existence of intrusion and assess the extent of
    a threat, if any, before dispatching the security personnel. If the
    existence of an intrusion is verified, either by CCTV or security
    personnel in the area, a law enforcement authority should be notified
    immediately. If possible, the intruder(s) found by the security
    personnel should be searched and detained until arrest by local police.
6. Emergency Procedures
    The licensee should provide procedures and equipment to maintain
    the level of access control and SNM and facility protection during
    conditions of emergency or equipment failure. Emergency procedures
    should be developed and executed in a manner consistent with safety.
    a. Evacuation Procedures
    During emergency conditions which require evacuation of part
    or all of the facility, temporary SNM checking stations should be
    established at the perimeter of the protected area or at a personnel
    collection area outside the protected area. All individuals should be
    searched for concealed SNM before being released from the protected area
    or collection area. In addition, a roll of all individuals who had
    entered the evacuated area should be taken to ensure that all have
    evacuated safely. If an evacuation or other emergency alarm sounds,
    guards and watchmen should take position at prearranged surveillance
    points to ensure that:
    (1) Proper evacuation routes are being observed,
    (2) SNM is not being tossed over the protected area
    perimeter barrier, and
    (3) No one attempts to gain unauthorized access to the
    protected area during the emergency.
    b. Failed Detection Equipment
    Failed detection equipment should be repaired as quickly as
    possible. In the interim, alternate access or exit points or hand-held
    detection devices or hands-on search procedures should be employed. In
    no case should the failure of equipment be allowed to compromise the
    protection of the facility or the SNM within the facility.
