1. A nuclear fuel lattice structure, comprising:
a body having a structure including a plurality of webbings having outer surfaces that define a network of interconnected channels located within an envelope surface of the body,
wherein a baseline of the webbings is an implicit surface of a mathematically-based periodic solid,
wherein the mathematically-based periodic solid is a triply periodic minimal surface (TPMS),
wherein at least a portion of the channels extend from a first outer surface of the body to a second outer surface of the body,
wherein the structure has a volumetric density of 35% to 85%,
wherein a composition of the structure includes a nuclear fissionable fuel having an enrichment of up to 20%, and
wherein a specific enrichment of the structure (% enrichment per unit volume) is constant ±2%.
