THE USE OF MONITORING AND LOGGING IN EURATOM SAFEGUARDS
In plants which have been designed and built over the last few years, increasing attention has been paid to security and health physics aspects. This tendency, coupled with the advances in measurement technology, nuclear material handling techniques and computerization has led to increased automation of processes within the nuclear fuel cycle. From a safeguards point of view this has meant that the material being controlled has become more and more inaccessible. As a consequence, the Euratom Safeguards Directorate has been designing monitoring and logging systems into safeguards approaches for some time and has now built up a considerable amount of practical experience. In general terms, these systems are designed with a sensor to respond to all "events of interest" (e.g. movement of a crane, passage of a fuel element) and a logging mechanism which records the event in a tamperproof way. If necessary the system can be connected to a video system which is triggered by the event to record what is happening in the field of view. It is believed that these systems represent an important new element of safeguards strategies providing a solution to problems which other safeguards measures cannot solve. Examples are given of practical applications and of other possible future applications.
