Zusammenfassung:	A tamper prevention system (90) for an article (2) to be protected. The tamper prevention system (90) comprises an enclosure (92) for receiving, in use, the article (2) to be protected. The enclosure (92) includes a sealable evacuation port (94) for applying a vacuum. The tamper prevention system (90) further comprises a monitoring and detection unit (50), contained within the enclosure 92. The monitoring and detection unit (50) includes a pressure sensor (80), the pressure sensor (80) being adapted to periodically or continuously sense the magnitude of the pressure inside the enclosure (92). The monitoring and detection unit (50) further includes a processor (54), coupled to the pressure sensor (80). The processor (54) is operable to determine that the enclosure (92) has been opened since sealing of the enclosure (92) under vacuum when it determines that a pressure detected by the pressure sensor (80) has undergone a predetermined change. The invention also relates to a method of tamper proofing an article (2) to be protected. The article (2) to be protected may be a sealing bolt for sealing nuclear containers, but it is not limited to such sealing bolts. Indeed, the use of such a tamper prevention system is not limited to the size of the article to be protected, nor to the industry in which the article may be used.
