  There has been an increasing interest in the monitoring of nuclear fuel for
power reactors by detecting the anti-neutrinos produced during operation. Small
liquid scintillator detectors have already demonstrated sensitivity to
operational power levels, but more sensitive monitoring requires improvements
in the efficiency and uniformity of these detectors. In this work, we use a
montecarlo simulation to investigate the detector performance of four different
detector configurations. Based on the analysis of neutron detection efficiency
and positron energy response, we find that the optimal detector design will
depend on the goals and restrictions of the specific installation or
application. We have attempted to present the relevant information so that
future detector development can proceed in a profitable direction.
