Lead-bismuth target design for the subcritical multiplier (SCM) of the accelerator driven test facility (ADTF).

Accelerator-Driven Subcritical System for Disposing of the U.S. Spent Nuclear Fuel Inventory

“…A detailed target design that utilizes LBE as the target material was performed at ANL in the early 2000s [10]. In this design, physics, thermal-hydraulic, radiation effects, and structure analyses have been iterated to satisfy the required engineering constraints.…”

“…The required operating conditions for a satisfactory HT-9 ferritic steel structure performance determine the main design criteria for the thermal hydraulics design analyses. The maximum surface temperature of the steel structure material is limited to less than 600 0 C and the maximum liquid mobile fuel velocity is restricted to less than 2 m/s for LBE and less than 3 m/s for liquid lead [10]. The reactor physics and the thermal hydraulics analyses were coupled to define the ADS concept.…”

Conceptual design of minor actinides burner with an accelerator-driven subcritical system.

“…A highly detailed target design that utilizes LBE as the target material was designed at ANL in the early 2000s [10]. In this design, physics, thermalhydraulic, and structure analyses have been iterated to satisfy the engineering constraints required for a safe system.…”

MEGAPIE analytical support task : characterization of lead-bismuth eutectic and sodium-cooled tungsten target materials for accelerator driven systems.

“…The high gas production rate affects the mechanical properties of the window material, which requires experimental data for realistic lifetime prediction of the structural material. Structural analysis [4] utilizing experimental data with lower helium per atomic displacement shows that the beam window may be able to operate for full power year with 40 µA/cm 2 current density.…”

“…Engineering and neutron yield considerations require extending the target length. The thermal-hydraulics analyses require a small target length extension to insure the flow stability of the lead-bismuth eutectic in the target area and the appropriate temperature distribution in the target structure [4], which represents the minimum extension length. The neutron yield was analyzed as a function of the target length for 600-and 1000-MeV protons.…”
