Diffractometer for residual stress analysis, called RESA, has been installed at JRR-3 (Japan Research Reactor No.3) guide hall in JAEA (Japan Atomic Energy Agency) since 1993 and the fundamental studies on the materials engineering have been performed using RESA. Recently, not only academic users but also industrial users are interested in using the neutron stress measurement for ensuring the reliability of mechanical components and the number of such users is rapidly increasing each year. To respond to the increase of users of RESA, RESA has been upgraded to improve efficiency and versatility, and RESA-2 has been installed at T2-3-2 beam port in JRR-3 guide hall as well. Current status of RESA-1 and RESA-2 will be introduced in the presentation.
