  The SNO+ experiment, currently undergoing commissioning, will be a large
scale liquid scintillator detector capable of studying a variety of physics
topics, with the highest priority being a sensitive search for neutrinoless
double beta decay. The collaboration has recently decided to use 130Te as the
candidate isotope for this search, having developed a new approach to the
purification and loading of tellurium into liquid scintillator. An initial
Phase I demonstrator with a 0.3% Te loading is expected to reach sensitivities
to Majorana neutrino masses approaching the top of the inverted neutrino mass
hierarchy. If successful, there is significant scope for further enhancements
that could lead to measurements covering the vast majority of the inverted
hierarchy range with high sensitivity.
