Abstract EN

This work presents a systematic methodology for physical protection system design of nuclear facility and its nuclear material inventory.

The design of an effective physical protection system includes the determination of the physical protection system objectives, the initial design of a physical protection system, and, probably, a redesign or refinement of the system.

To develop the objectives, the designer must begin by gathering information about facility operations and conditions, such as comprehensive description of the facility, operating states, and the physical protection requirements.

The designer then needs to define the threat.

This involves considering factors about potential adversaries: class of adversary, adversary’s capabilities, and range of adversary’s tactics.

Next, the designer should identify targets.

Determination of whether or not nuclear materials are attractive targets is based mainly on the case or difficulty of acquisition and desirability of the material.

The designer now knows the objectives of the physical protection system, that is, “what to protect against whom” or on other word "Design Basis Threat (DBT)".

The next step is to design the system by determining how best to combine such elements as fences, vaults, sensors procedures, communication devices, and response force personnel to meet the objectives of the system.
