Abstract Scope |
The Tritium Modernization Program produces tritium for US national security needs by irradiating tritium-producing burnable absorber rods (TPBARs) in the Watts Bar Nuclear commercial power plant. To understand in-reactor performance of TPBAR components, four irradiation experiments were conducted as part of the TPBAR Materials In-reactor Separate-effects Test (TMIST) series, irradiated at the Advanced Test Reactor beginning in 2006 and continuing to the present. Each experiment focused on a different TPBAR component, including Zircaloy-4 liners (TMIST-1), aluminide-coated Type 316 stainless steel (TMIST-2), LiAlO2 pellets (TMIST-3) and Ni-plated Zircaloy-4 getters (TMIST-4). Each of the four experiments utilized active temperature control and included online measurement of temperature, gas flows, tritium concentration/speciation, and other parameters. In each experiment, the results were a combination of in-situ measurements and post-irradiation characterization, and the vehicle designs had to accommodate both. The presentation will highlight unique details of the TMIST irradiation vehicles that enabled these challenging, first-of-a-kind experiments. |
