Progress in converting {sup 99}Mo production from high- to low-enriched uranium--1999. Open
Over this past year, extraordinary progress has been made in executing our charter to assist in converting Mo-99 production worldwide from HEU to LEU. Building on the successful development of the experimental LEU-foil target, we have desi…
Demonstration of {sup 99}MO production using LEU metal-foil targets in the cintichem process. Open
In March and September 1999, demonstrations of the irradiation, disassembly, and processing of LEU metal foil targets were performed in the Indonesian BATAN PUSPIPTEK Facilities. These demonstrations showed that (1) irradiation and disasse…
Development of annular targets for {sup 99}MO production. Open
The new annular target performed well during irradiation. The target is inexpensive and provides good heat transfer during irradiation. Based on these and previous tests, we conclude that targets with zirconium tubes and either nickel-plat…
Postirradiation examinations of U-Pu-Zr fuel elements from subassemblies X419 and X419A Open
Initial postirradiation examination of IFR type U-Pu-Zr fuel elements from X419 and X419A are reported. Characterization of the fuel at three levels of burnup, 0.8 at.%, 1.9 at.%, and 2.7 at.% is presented. Fuel swelling, microstructure, c…
