THE TN-MTR PACKAGING

The TN-MTR packaging is a type B(U)F cask, specially designed for the transport of irradiated MTR (Material Testing Reactor) and TRIGA fuels. In 1996, Transnucleaire and Transnuclear, Inc. began a cooperative effort to develop a new packaging for the transport of spent Materials Test Reactor fuel. According to the IAEA regulation. this package is a type B(U) containing fissile material. This packaging is intended to replace the IU-04 (\"Pegase\"). which has been in service since 1967. The TN-MTR packaging will be able to transport MTR fuels in France and abroad. In particular it could be used to transport MTR fuels from research reactors back to the United States. To minimize the number of these transports. Transnuclear has developed a high capacity basket (up to 68 MTR elements) that is adequate for a large variety of MTR and TRIG A fuels. Since this packaging must be operated in many facilities, it has been especially designed to be easily handled and its operation does not require elaborate equipment.
