Recently, each industry is searching for the most suitable manufacturing process to reduce the cost. Especially, the production method of material, the improvement of processing technique, and the selection of cheap materials are being discussed. Therefore, it is the top-priority issue to examine safety and reliability of the material strength to reexamine these. In the industrial user, residual stress has been evaluated by the X-ray stress measurement or by the finite element method (FEM) etc. Neutron is the only one probe to measure the lattice strain nondestructively at the deep inside of materials. The promotion program of technology transfer on neutron application has been implementing in Japan since 2006. The experiments executed in this program are the residual stress evaluation in the welded boiler tube, carburized steel, and welded sample that imitates the stress measurement in the large structure etc. Some experimental results obtained in the program will be presented at this conference.

In the manufacturer, residual stress has been evaluated by X-ray stress measurement or by FEM etc. Although neutron is the only one probe to measure the lattice strain nondestructively at the deep inside of materials, very few industrial users actually attempt the neutron diffraction method. The promotion program of technology transfer on neutron application has been implementing in Japan since 2006. The experiments executed in this program are the residual stress evaluation in the welded boiler tube and welded sample that imitates the stress measurement in the large structure etc. In addition, the possible application of the oscillation method to the neutron stress measurement in coarse polycrystalline materials was discussed.

JAEA has been conducting practical irradiation for production of Neutron-Transmutation-Doped-Silicon (NTD-Si) since 1977. The JRR-3 and JRR-4 of JAEA are used to irradiate Silicon ingots at present. A Silicon ingot is irradiated with an irradiation facility in the heavy water reflector tank in the JRR-3. The maximum size of silicon ingot which can be irradiated in the facility of JRR-3 is about 152 mm (6 inches) in diameter and 600 mm in length. A silicon ingot is irradiated in the irradiation facility by the side of reactor core in the JRR-4. The maximum silicon ingot which can be irradiated in JRR-4 is about 125 mm (5 inches) in diameter and the 400 mm in length. The amount of NTD-Si was about 3.7 tons at the JRR-3 and about 0.7 tons at the JRR-4 in 2006 Japanese fiscal year. We are planning to investigate the expansion technology of the NTD-Si productivity in the JRR-3.
