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 350C to 500C 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, SrO, ZrO and YO in the LBE.

This paper is compiled as a record of oral presentation by O.YAMAMURA at RECOD' 91 in April 15. 1991 in Sendai Japan with more than 600 attendance. It contains a proceeding, a manuscript of oral presentation and a manuscript of viewgraphs. The abstract of presentation is as belows. Since the start of construction of the Tokai Reprocessing Plant (TRP) in 1971, large efforts were taken by the Power Reactor and Nuclear Fuel Development Corporation (PNC) and various organizations to root the LWR fuel reprocessing technology in Japan. These efforts produced many achievements around the TRP, and now the future plan for the TRP is being studied.

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.
