Overview of shipment of low-level radioactive waste

Under the terms of an agreement between the two companies on disposal of low-level radioactive waste, Chubu Electric ships its low-level radioactive waste to Japan Nuclear Fuel's Rokkasho-Mura Low-Level Radioactive Waste Disposal Center in Aomori Prefecture.

Counting this shipment, Chubu Electric Power will have made a total of 22 shipments of low-level radioactive waste to the Low-Level Radioactive Waste Disposal Center.


Low-level radioactive waste included in this shipment

The low-level radioactive waste included in this shipment consists of unburnable solid wastes put in drums that are then filled with mortar to solidify the content. The external appearance, dose-equivalent rates, and other aspects of the shipment have been confirmed by the Japan Nuclear Energy Safety Organization (JNES).


Past shipments of low-level radioactive waste

This will be the 22nd shipment of low-level radioactive waste from the Hamaoka Nuclear Power Station since the first such shipment was made in 1993 to the Rokkasho-Mura Low-Level Radioactive Waste Disposal Center. The following table provides the details of each shipment:


*This shipment's scheduled date and number of drums


Summary description of transport containers to be used in this shipment


Material Size Weight
Steel 3.2m (L) * 1.6m (D) * 1.1m (H) Approx. 1 ton

These transport containers have been designed pursuant to applicable laws and regulations and have passed safety inspections performed by the Nippon Kaiji Kentei Kyokai.


Summary description of the vessel to be used in this shipment


Vessel Length Width Load capacity Maximum number of transport containers that can be loaded
(number of drums)
Seiei Maru Approx. 100m Approx. 16m Approx. 3,000 tons 384 (3,072 drums)

The Seiei Maru is owned by Nuclear Fuel Transport Co., Ltd.

Collisions are highly unlikely: The Seiei Maru transports waste employing rigorous safety planning and safety measures, including the installation of radar and anti-collision equipment and use of efficient route planning. Even in the event of a collision, the Seiei Maru is double-hulled to make sinking highly improbable.

The Seiei Maru is to arrive with this shipment at the Port of Mutsu Ogawara on Thursday, March 8, 2007.


Low-level radioactive waste storage capacity and number of drums in storage

As of January 31, 2007


Solid-waste repository Capacity Number of drums in storage
No. 1 Equivalent of 7,000 Equivalent of 3,532
No. 2 Equivalent of 35,000 Equivalent of 32,850
Total Equivalent of 42,000 Equivalent of 36,382

Land-transport safety measures

Safety measures taken for the trucks used in land transport include safe securing of the cargo in place and proper labeling. Other safety measures include the stationing of traffic control personnel to direct traffic at key intersections along the route.

In addition, a transportation headquarters will be in place at the Hamaoka Nuclear Power Station to ascertain the status of the shipment and to establish a network ensuring smooth communications regarding the shipment. Tools and materials such as equipment for measuring radiation and materials for safeguarding against exposure to radiation will be in place at the transportation headquarters at the station, as well as at other locations.


Countermeasures in the event of an accident (communication network)

In the event of an accident during shipment, related government agencies, police departments, fire departments and other bodies will be notified, and related information will be promptly released to the media.

Those responsible for the shipment will take various measures, including establishing prohibited-entry zones accessible to authorized personnel only, fighting and preventing the spread of any fires, and preventing the spread of and cleaning up any contamination. Subsequent emergency measures are to be implemented based on circumstances in cooperation with police and fire departments.


Future shipment plans

This is the final shipment of low-level radioactive waste for the 2006 fiscal year. Plans for shipments in the 2007 fiscal year and beyond are currently being prepared in cooperation with the various parties involved.
