Lead-Bismuth Eutectic (LBE) is used as a spallation neutron target and coolant materials of Accelerator Driven System (ADS), and many kinds of elements are produced as spallation products. It is important to evaluate the release and transport behavior of the spallation products in the LBE. The inventories and the physicochemical composition of the spallation products produced in LBE have been investigated for an LBE loop in the ADS Target Test Facility (TEF-T) in J-PARC. The inventories of the spallation products in the LBE were estimated using the PHITS code. The physicochemical composition of the spallation products in the LBE was calculated using the Thermo-Calc code under the conditions of the operation temperatures of LBE from 350$$^{circ}$$C to 500$$^{circ}$$C and the oxygen concentrations in LBE from 10 ppb to 1 ppm. The calculation showed that the 5 elements of Rb, Tl, Tc, Os, Ir, Pt, Au and Hg were soluble in LBE under the all given conditions and any kinds of compound were not formed in LBE. It was suggested that the oxides of Ce, Sr, Zr and Y were stable as CeO$$_{2}$$, SrO, ZrO$$_{2}$$ and Y$$_{2}$$O$$_{3}$$ in the LBE.

Representative spallation product elements in a lead-bismuth eutectic (LBE) loop in the ADS Target Test Facility (TEF-T) were selected. Chemical compounds of the elements and their concentrations which can be formed in the LBE were evaluated by one point equilibrium calculation by using the integrated thermodynamic calculation system Thermo-Calc.
