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.

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.

A Consideration on Issues for Safe and Secure Transport of Nuclear Materials.

The Japan Atomic Energy Agency (JAEA) is planning to procure Mixed Oxide (MOX) powder from the Rokkasho Reprocessing Plant (RRP) of the Japan Nuclear Fuel Limited (JNFL), as raw material to fabricate reload-fuel for the prototype fast breeder reactor "MONJU" and the experimental reactor "JOYO" at about 2014. The diameter of MOX storage canister used in RRP is larger than the one used in the Tokai Reprocessing Plant (TRP) of JAEA, and therefore the canister has a large capacity. Because of this, the existing packagings are not to be used and development of new packaging has started in 2002. The design of the packaging needs to comply with the requirements for Type B(U)F package specified in the TS-R-1 of the IAEA safe transport regulations and has targeted to ensure high performance of sub-criticality and obtain an efficient performance for heat release, considering a large amount of plutonium. The design of the package is found to satisfy those requirements. In order to validate the design, a series of prototype tests using a prototype packaging has been conducted: heat convection test, handling test in RRP and regulation tests (9m drop, fire, etc.). In the paper, features of the new packaging and test results are presented.

JAEA is planning to procure MOX powder from the Rokka-sho Reprocessing Plant (RRP) of the JNFL in Aomori prefecture, as raw material to fabricate reloaded-fuel for the prototype fast breeder reactor "MONJU" and the experimental reactor "JOYO" at about 2014. A development of new packaging and a preparation of specialized transport system for responding to requirements of Category I nuclear materials have been implemented. The design of the new packaging started in 2002. A series of prototype tests using a prototype packaging has been con-ducted: heat convection test, handling test in RRP, and regulation tests according to the requirements for Type B(U)F package specified in the TS-R-1 of the IAEA safe transport regulations. The design of the dedicated transport container was conducted to accommodate as many packages as possible, based on an ISO 20-foot container. An assessment of sea transport for MOX powder was also conducted, as part of the safety assessment during transport by ship.

Over 35 years, the Japan Atomic Energy Agency (JAEA) to promote nuclear basic research and nuclear fuel cycle done by its predecessors; JAERI and JNC (PNC) has been accumulating experiences to transport wide range of nuclear materials: MOX fuels and powder for fast breeder reactors, MOX spent fuel for post irradiation examination and uranium fuel elements for test / research reactors, etc.. This paper introduces our experiences in transporting MOX fuels and powder, and additionally technology and system in terms of transport method, emergency preparedness and quality assurance developed reflecting trends in Japan and world, then shows one of future perspectives for MOX transport.
