The protection of nuclear installations against malicious acts can take a number of different forms. This report addresses only issues related to the sabotage of nuclear facilities – prevention or mitigation of sequences initiated by malicious acts that may have potential radiological consequences. Nuclear power plants have good physical protection systems (PPSs) and procedures, and they are designed to minimize the likelihood of an accident and in the event of an accident, not to release radioactive material in an uncontrolled manner. The objective of this report is to provide methods for evaluating and for proposing corrective actions aimed at reducing the risk related to any malicious act that, directed against a nuclear power plant, could endanger the health and safety of plant personnel, the public and the environment.

One of the main threats to nuclear facilities can involve external or insider adversaries or both together in collusion (coop eration for an illegal or malicious purpose with another insider adversary or with an external adversary). In these case, the main effort is to prevent and protect against unauthorized removal of nuclear material and sabotage of nuclear material and facilities by insiders. This report applies to any type of nuclear facility – notably nuclear power plants, research reactors and other nuclear fuel cycle facilities – whether in design, construction, commissioning, operation, shutdown or decommissioning

The potential for criminal or intentional unauthorized acts involving or directed at nuclear or other radioactive material or their associated facilities and associated activities is an ongoing global concern. Because of their widespread use, nuclear and other radioactive materials are vulnerable to sabotage, or to being stolen, lost or acquired illegally by individuals or groups that may use th em for malicious purposes. The objective of a nuclear security regime is to prevent, detect and respond to nuclear security events, and to protect persons, property, society and the environment from harmful consequences associated with nuclear and other radioactive materials.
