Description

The image is a diagram showing the nuclear thermal propulsion stage. The diagram is divided into three sections, with the first section showing the nuclear reactor, the second section showing the nuclear reactor with a nex-reactor, and the third section showing the nuclear reactor with a radiation-derived reactor. In the image, there are several arrows pointing to different parts of the diagram, indicating the flow of energy and the components involved in the nuclear thermal propulsion stage. The diagram also includes a few numbers, possibly representing measurements or calculations related to the nuclear reactor.
