DOE meeting focuses on Marshall Islands’ legacy activity
The Department of Energy Office of Environment, Health, Safety and Security (EHSS) held its annual meeting this month with the government of the Marshall Islands. The two-and-a-half-day meeting, in Honolulu, Hawaii, focused on ongoing cooperative efforts and programs related to the legacy of U.S. nuclear weapons testing from the 1940s and 1950s. The United States began cleanup operations on the islands in the 1970s.

In the separation nozzle process, the enrichment of 235U is achieved by extremely high centrifugal forces in a curved flow of UF6 diluted by a light gas. Remarkable progress has been made in the economy of the process by bringing up the gas pressure and by introducing a nozzle system with double deflection of the jet. While the specific energy consumption is comparable to that of the American diffusion plants, the separation effect per stage is considerably higher than that of the classical technology. Therefore an economical application is possible for smaller and correspondingly cheaper plants. The process finds its first commercial application within the framework of German/Brazilian Cooperation. A so-called First Cascade consisting of 24 separation nozzle stages is under construction in Brazil. The development of components for commercial separation nozzle plants is well under way.
