JAEA proposes transmutation of minor actinides by accelerator-driven systems (ADS). To obtain the data for ADS design, JAEA plans to construct the ADS Target Test Facility (TEF-T) within the framework of the J-PARC project. In TEF-T, a 250 kW proton-beam-driven LBE (Lead-Bismuth Eutectic) spallation target will be installed to prepare an irradiation database for candidate ADS structural materials. Design activities of the LBE target and target trolley have been progressed. Conceptual design of hot-cells for LBE target loop maintenance and PIE (Post Irradiation Examination) of irradiated samples have been finished. Two LBE loops were manufactured. One is a loop for TEF-T target mock-up and the other is that for collection of material corrosion characteristics in flowing LBE. Oxygen potential control systems for LBE flow have been also developed. Remote handling tests for the target exchange are underway. In this paper, current activities and studies to realize TEF-T will be presented.

To evaluate the lifetime of the beam window of an accelerator-driven transmutation system (ADS) and spallation neutron source, material irradiation programs, the STIP (SINQ target irradiation program, SINQ; Swiss spallation neutron source) and MEGAPIE (MEGAwatt Pilot Experiment), have been executed. Part of the specimens were transported to JAEA and post irradiation examination (PIE) of the specimens was carried out. In this presentation, in addition to representative results of the PIE, our experience and knowledge of irradiation experiments and PIE processes will be introduced. These information will be useful for high energy particle irradiation experiments and PIE planed under the frame work of RaDIATE.

Beam window and structural materials for spallation neutron source and ADS are damaged by irradiation with high energy protons and spallation neutrons. In order to clarify the radiation damage characteristics of materials under spallation conditions, irradiation programs such as STIP (SINQ Target Irradiation Program) and MEGAPIE (MEGAwatt Pilot Experiment) are centered on the Swiss Paul Scherrer Institute (PSI) in Switzerland. In these programs, various materials have been irradiated with 580 MeV protons at PSI accelerator, and the participating countries share the PIE. JAEA also transported some of the irradiated samples and conducted PIE. In this presentation, we will introduce the characteristics of the spallation environment, the outline of these material irradiation programs, and the typical results and knowledge obtained by PIE.
