JAEA has developed a TMS which can monitor the movement of nuclear material convoys to make safe and proper transport of nuclear materials. The TMS mainly consists of the location information monitoring system to monitor the location of the convoys and the visual information monitoring system to survey around the convoys. The TMS can send information in real-time to the TCC located at the shipper site. The JAEA has operated the TMS for ground transportation of MOX fuels since 2005, and the JAEA solved visual control problems that were observed during the operational experience and upgraded the system by adding the automatic communication control system, etc. In the case of emergency during transport, the TMS can send much more detailed visual information of the accident site to the TCC, which is useful for planning and executing an effective response. This paper reports the overview of the upgraded TMS and its effectiveness.

Upgrade of the transport monitoring system of nuclear materials

Proceedings of INMM 52nd Annual Meeting (CD-ROM), 6 Pages, 2011/07

The Japan Atomic Energy Agency (JAEA) has developed a transport monitoring system (TMS), which tracks the movement of nuclear material convoys in real time, and which is consistent with the physical protection requirements for transport of Category 1 nuclear materials. The TMS has been used for land transport of MOX fuels since 2005. JAEA solved some problems that were observed during operational experience and upgraded the system by adding the following features. In the case of emergency during transport, the upgraded TMS can send much more detailed visual information of the accident site to the TCC, which is useful for planning and executing an effective response. This paper presents the features of the TMS and the results obtained from operational experiences.

Development of monitoring system for land transport conditions of nuclear materials

Proceedings of 16th International Symposium on the Packaging and Transport of Radioactive Materials (PATRAM 2010) (CD-ROM), 6 Pages, 2010/10

It is very important to monitor land transport conditions continually in order to implement the safe and smooth transport of nuclear materials, especially to quickly obtain the accurate visual information and carry out emergency response swiftly and properly in the event of transport accident. Plutonium Fuel Development Center of JAEA developed the system for real-time monitoring of transport conditions of nuclear materials. The location information from GPS is transmitted to ground station from transport monitoring equipment installed on vehicle of convoy via the satellite, and transmitted to the TransportControlCenter (TCC) periodically through telephone line. The location information from GPS is also directly transmitted to ground station from transport monitoring equipment by ground wave and transmitted to TCC through telephone line. In both cases, location information is shown on a monitoring panel in TCC. Image monitoring system is one for transmitting motion picture taken by cameras equipped on the roof of vehicle of convoy to TCC through ground wave and showing it on a monitoring panel in TCC. It is also possible to transmit image to TCC with this system, which is taken by the portable camera for emergency response. The camera is taken out of transport monitoring equipment, installed on the proper place, and remotely controlled from TCC. For the development of transport conditions monitoring system, following requirements were considered taking into account the use in emergency response and long-term transport, -Compactness to fit limited space on the vehicles -Applicability for conditions in vibration and temperature change anticipated in transport operation. -Long-term stability and redundancy of power supply The developed system is very useful not only for monitoring normal transport conditions but also for planning emergency response program because it can transmit accurate visual information to TCC in the event of transport accident.

The more stringent physical protection measures are required for the Plutonium Fuel Development Center (PFDC) in Japan Atomic Energy Agency which has some category I facilities. In order to maintain physical protection measures, it is one of importance functions to keep and improve the guards skill. PFDC has performed two kind of exercise, one is the joint exercise with the response force and the other is the internal exercise. In the internal exercise, intruders and response forces are simulated by employees in order to perform practical exercise. However, this exercise is needed many kind of preparation works and many employees and the number of it is limited. PFDC newly introduced the table top exercise (TTX). The TTX is easy to perform without many preparation works and employees. Furthermore, it is possible to perform the exercise with wide range scenarios. This report shows overview of PFDC table top exercise and advantages and future issues of it.
