  We carried out a study of neutrino detection at the experimental fast reactor
JOYO using a 0.76 tons gadolinium loaded liquid scintillator detector. The
detector was set up on the ground level at 24.3m from the JOYO reactor core of
140MW thermal power. The measured neutrino event rate from reactor on-off
comparison was 1.11\pm1.24(stat.)\pm0.46(syst.)events/day. Although the
statistical significance of the measurement was not enough, the background in
such a compact detector at the ground level was studied in detail and MC
simulation was found to describe the data well. A study for improvement of the
detector for future such experiments is also shown.
