Abstract: Neutrinoless double-beta decay is one of the most interesting nuclear reactions. In this talk, I introduce Nuclear Lattice Effective Field Theory as a new tool in nuclear theory. It allows to address nuclear structure and reactions simultaneously. I show assorted results obtained so far. In particular, I will address the recent work on triton beta-decay, which is an important first step in addressing neutrinoless double-beta decay in this framework.
