Untersuchungen zur Einführung der Datenfernübertragung in der internationalen Überwachung der Kerntechnik
98 S., 1999
The Safeguards Directorate of the European Commission (Euratom) as well as the
International Atomic Energy Agency (IAEA) plan to substitute unattended remote
monitoring systems for on-site inspection effort in nuclear facilities. The most
important requirements for such systems are the authenticity and confidentiality
of the safeguards data received in Vienna or Luxemburg as well as the cost
effectiveness of system operation in comparison to the current on-site inspections.
Two field trials were performed registering digital optical data under real
operating conditions in a nuclear facility and remotely transmitting these data
via ISDN as well as satellite link. It was possible to demonstrate a technique
with time-delayed transmission of optical data which almost represented a system
appropriate for routine safeguards application. Due to the authentication of the
optical data, the inspectorates of IAEA and Euratom would be in the position to
arrive at the required independent safeguards conclusions. Within the European
Union ISDN could be a viable transmission medium for large data volumes. Technically,
the transmission media ISDN and satellite link appear to be equivalent. It is planned
to carry out a one-year follow-up field trial in cooperation with IAEA and Euratom,
in order to arrive at quantitative or final statements regarding the following
issues: operational costs, system reliability, handling of false alarms, long-term
stability of data storage and data transmission media, data security, key
management, cost savings on the part of the facility operator.
