Abstract

A nuclear reactor system includes a drillhole that extends from a terranean surface through one or more subterranean formations. The nuclear reactor system includes a reactor core positioned in the drillhole, the reactor core comprising at least one nuclear fuel element. The nuclear reactor system includes a primary coolant system configured to transport a primary fluid coolant between the reactor core and a heat exchanger. The nuclear reactor system includes a secondary coolant system thermally coupled to the primary coolant system via the heat exchanger and configured to transport a secondary fluid coolant between the heat exchanger and the terranean surface.
