1. A cryogenic storage system, comprising:
a primary container;
a first insulation layer disposed below a primary bottom of the primary container;
a secondary container disposed outward of the primary container; and
a secondary bottom disposed below the primary bottom of the primary container, where the secondary bottom is coupled to the secondary container through an expansion joint, and where the expansion joint is configured to permit an expansion and a retraction of the secondary bottom independent from the secondary container,
a second insulation layer disposed below the secondary bottom, wherein the cryogenic storage system includes a thermal element disposed in soil beneath the second insulation layer, and wherein the thermal element is configured to militate against a rapid change in temperature of the soil if a cryogenic liquid leaks from the cryogenic storage system.
