Deep Fission lowered and retrieved a full-sized, non-nuclear reactor canister inside a test borehole using standard commercial drilling equipment. The test validated the core deployment sequence for the company's proposed underground small modular reactor concept. Utilizing existing industrial hardware reduces the need for specialized nuclear equipment development during future deployment phases.

A full-sized prototype of the canister that will hold the Gravity reactor has been installed and then retrieved from a borehole using standard equipment already in commercial service in the drilling industry. ;

California-based Deep Fission is developing the Gravity reactor, a small modular reactor designed to be placed underground in an optimised borehole one mile (1.6 km) deep.

The company has announced that it has now successfully lowered the 20 foot (6 metre) canister to a depth of 100 feet inside a 34 inch (86 centimetre) wide borehole, aligned it, and brought it back to the surface, an emplacement and retrieval sequence that Deep Fission's deployment model depends on. The prototype canister is a full-size, non-nuclear replica of the canister designed to house the Gravity reactor core.
