TRANSNUCLEAR INC.

Transnuclear offers an integrated logistics model that combines transportation know-how with packaging design expertise in a single offering that provides a one-stop, holistic solution for commercial and government customers in North America. Services include:

• Shipment of front-end materials such as U₃O₈, natural and enriched UF₆, UO₂ powder and pellets or fabricated fuel
• Shipment of back-end materials such as irradiated nuclear material and orphan radioactive sources
• Management of large-scale, domestic and international transportation campaigns
• Design, licensing and fabrication of packagings
• Package operations, fleet management and supplier evaluation and inspection

Designed for the U.S. EPR™ reactor, Transnuclear’s NUSTOR™ used fuel racks are adaptable for use in all reactor types, offering customers flexible fuel management options and next generation technology.

NUSTOR™ racks utilize Metal Matrix Composite (MMC) poison material for criticality control. Our MMCs do not require extrusion, use a more corrosion resistant matrix alloy, and reduce dissimilar metal contact. As a result, TN has eliminated the major causes of pitting corrosion in other MMCs and consequently eliminated the need to anodize.

Design and licensing are underway and the first NUSTOR™ rack will be installed in a U.S. reactor pool in 2013.

Innovative technology. Practical execution. From the workhorse NUHOMS™ storage system to advanced engineered products, Transnuclear’s designers have licensed a range of casks that today meet all the used fuel storage needs of US utility and government customers.

Cutting edge engineering products include the AREVA Automated Welding System, NUSTOR™ rack, MP197HB, and NUHOMS^® Dry Shielded Canisters and Horizontal Storage Modules that offer the highest capacity, burnup, heat load, thermal and seismic options available.

For many utilities, used fuel loading is not a routine activity. With the Transnuclear pool-to-pad team, utilities receive a proven, comprehensive used fuel management solution that minimizes cost and risk. Services include fuel loading, handling and inspection; procedures and training; crew and equipment mobilization; and ISFSI design, construction and startup.

Today, U.S. reactor operators face limited options for disposal of irradiated reactor components. The NUHOWS system provides an ideal on-site interim storage solution for Class B and C irradiated reactor hardware components such as control rod blades, jet pumps and fuel channels.

NUHOWS is designed intentionally to mirror TN’s proven NUHOMS^® Dry Shielded Canister storage system. The Rad Waste Container, like the DSC, is stored in a Horizontal Storage Module and transportable via TN’s MP197HB shipping package. In addition, the RWC minimizes size reduction requirements and under water component segmentation, and allows for multiple loadings. One RWC accommodates up to a decade of irradiated components.
