Nuclear Security Regulations

9 (1) Every protected area shall be enclosed by a barrier that is located at its perimeter.

(2) Subject to subsection (3), the barrier shall be designed and constructed to inhibit any unauthorized entry into the protected area and must be one or a combination of the following structures:

• (a) a fence at least 2.4 m in height constructed of wire chain links made of wire not smaller than gauge number 11, having openings whose sides do not exceed 6 cm in length, and topped with at least three strands of barbed wire or barbed tape installed parallel to the fence on brackets angled outward;

• (b) a wall at least 2.4 m in height, including any wall that forms part of a building, constructed of steel, wood, concrete, masonry or other substantial material or composites of such materials and, if it does not form part of a building, topped with at least three strands of barbed wire or barbed tape installed parallel to the wall on brackets angled outward; or

• (c) a structure that provides the same level of protection as those referred to in paragraphs (a) and (b).

(3) For facilities in respect of which a construction licence is issued after the day on which section 9.1 of these Regulations comes into force, the barrier must be designed and constructed to inhibit unauthorized entry into the protected area and must consist of

• (a) the following elements, namely,

  • (i) an exterior fence extending at least 3 m above grade but otherwise constructed to the specifications set out in paragraph (2)(a),

  • (ii) an interior fence extending at least 2.4 m above grade but otherwise constructed to the specifications set out in paragraph (2)(a), and

  • (iii) a separation of not less than 5 m between the two fences that is free of obstructions, other than guard posts, vehicle portals and intrusion detection and assessment devices; or

• (b) a structure, whether or not combined with other physical protection measures, that provides the same level of protection as the structures referred to in paragraph (a).

(4) Despite subsection (3), permanent security facilities such as guard posts and vehicle portals may join with the exterior and interior fences provided that a continuous barrier is maintained.

(5) The interior fence referred to in subparagraph (3)(a)(ii) is considered to be the perimeter of the protected area.

(6) Each gate, door, window or other means of entry or exit in the barrier shall be constructed so that it can be closed and locked.

(7) Those means of entry or exit shall be kept closed and locked except when persons or land vehicles are entering or exiting the protected area under the direct visual surveillance of a nuclear security officer.
