A review of investigations and upgrades during the past decade are presented for the small-angle neutron scattering spectrometer SANS-U owned by the Institute for Solid State Physics, The University of Tokyo at the research reactor (JRR-3) of the Japan Atomic Energy Agency (JAEA), Tokai, Japan. Among the two major upgrades of the SANS-U was highlighted the second upgrade carried out during 2008-2010. This includes the achievement of the increase of the incident beam flux by 3.2 times and of the lowermost Q vector to 3.8 x 10-4 Å-1 owing to an installation of focusing lenses and a high-resolution position sensitive detector consisting of a cross-wired position sensitive photomultiplier tube combined with a ZnS/6LiF scintillator on the SANS-U. The versatility of SANS-U is demonstrated by a variety of accessories and various types of scientific hot topics, including high-pressure experiments, Rheo-SANS, and deformation studies on tough gels, etc.
