|Abstract:||Recent advances in radio frequency communication technologies offer the motivation to consider the use of wireless communication in nuclear safeguards applications. From the Nuclear Safeguards Inspectorates' (NSI) point of view, wireless data transmission - which would be supplemental to wired communication - is attractive for the ease of installation and the ability to respond to the changing requirements as the inspection approach evolves, resulting in a reduction of costs. However, for wireless technologies to be considered as a viable complement to cables, a number of concerns have to be addressed. First, nuclear operators need to be guaranteed that RF transmission will not interfere with the facilities safety and physical security systems. On their side, the NSI must be satisfied that Containment and Surveillance equipment and data transmission processes will not be affected by the other existing RF equipment. Second, it is desirable, both for the NSI and the operators, that the data being transmitted is not available for analysis by a third party. In addition, the NSI require data to be authenticated as close to the point of acquisition as possible. This paper was prepared as an account of work performed and approved by the ESARDA Working Group on Containment and Surveillance. It is the first of a suite dedicated to bridging RF technologies with safeguards monitoring applications. The paper focuses on technological issues: it introduces basic concepts underlying wireless communication, including methods for transmission, issues on power consumption, frequency, range, and considerations on interference and noise resilience. It overviews state-of-the-art wireless technologies and presents a projection on wireless capabilities that are likely to be reached in the near future.|
