Press Release

March 07, 2012

BETHESDA, Md., March 7, 2012 – Transnuclear, Inc. (TN), an AREVA company, has unveiled an innovative and advanced dry cask system for use in marine environments. The NUHOMS® 32PTH2 system design was submitted to the U.S. Nuclear Regulatory Commission (NRC) for approval and should be available in 2014. It incorporates many lessons learned from previous fabrication, including a more robust corrosion-resistant design, a longer design life for a seaside environments, and can handle wind, salt and water usually associated with coastal locations.

“We’re very excited to introduce the NUHOMS® 32PTH2 system,” said Michael McMahon, CEO of Transnuclear, Inc. “It can withstand very high seismic and stringent dose requirements, which are of the upmost importance in delivering safe, quality solutions for our customers.”

The NUHOMS® system can hold 32 pressurized water reactor (PWR) spent fuel assemblies. Once filled, the canister is moved by trailer and secure transfer cask onto an Independent Spent Fuel Storage Installation (ISFSI) where the loaded canister is stored in a high seismic capacity/passively cooled concrete module.
As one of TN’s highest heat rejection capacity canisters/modules, the 32PTH2 system can safely accommodate higher burnup fuel and shorter cooling times to give customers a broader range of used fuel management options.

Transnuclear, Inc. provides services for the nuclear fuel cycle including transportation, storage, and handling of used nuclear fuel, radioactive waste, and other radioactive materials. As a subsidiary of TN International and part of the AREVA Group, the world leader in nuclear technology, Transnuclear offers the industry an unsurpassed level of experience and cost effective solutions.
