The reactor core generates heat in a number of ways:

Nuclear fission generator manual#

Nuclear reactors generally have automatic and manual systems to shut the fission reaction down if monitoring or instrumentation detects unsafe conditions.

To control such a nuclear chain reaction, control rods containing neutron poisons and neutron moderators can change the portion of neutrons that will go on to cause more fission. This is known as a nuclear chain reaction. A portion of these neutrons may be absorbed by other fissile atoms and trigger further fission events, which release more neutrons, and so on.

The heavy nucleus splits into two or more lighter nuclei, (the fission products), releasing kinetic energy, gamma radiation, and free neutrons. When a large fissile atomic nucleus such as uranium-235, uranium-233, or plutonium-239 absorbs a neutron, it may undergo nuclear fission. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor to reach criticality were stacked in a pile). As of 2022, the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. Nuclear generated steam in principle can be used for industrial process heat or for district heating. These either drive a ship's propellers or turn electrical generators' shafts. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Core of CROCUS, a small nuclear reactor used for research at the EPFL in SwitzerlandĪ nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. For nuclear stockpiles, see List of states with nuclear weapons. NASA also notes that the work done for this contract could have other future applications for propulsion systems for long-range spacecraft for deep space explorations."Nuclear pile" redirects here. It may not seem like much, but deployed singularly or in groups to support a lunar base, it could solve a lot of the challenges of the kind of prolonged occupancy of the moon that NASA plans to eventually establish through its Artemis program, which seeks to return humans to our largest natural satellite for ongoing science missions.Ĭonditions on the moon (and Mars for that matter) exaggerate a lot of the same challenges we face with other power sources, like solar, here on Earth: Namely, they have to be able to operate consistently regardless of the availability of sunlight and in harsh environments.

That’s about what a full charge on a current entry-level Nissan Leaf contains - but as a fission generator it would obviously provide that continuously. NASA is aptly partnering with the Department of Energy (DOE) on this project, and the specs include a 40-kilowatt power generation capability, capable of generating that for at least a decade. Each will be working with a few partners to develop their systems, which will be “initial concepts” only for the purposes of satisfying this particular contract, and each will receive roughly $5 million for their work, expected to take around 12 months. The winning bids for this award came from Lockheed Martin, Westinghouse and IX (a joint venture from Intuitive Machines and X-Energy). NASA announced on Tuesday that it’s contracting three suppliers to provide concept designs for nuclear fission energy systems designed for use on the moon.

Nuclear fission may have to overcome a public perception hurdle here on Earth in order to get the funding and development it needs to advance sufficiently to help our with our de-carbonization efforts, but the mostly empty lunar surface sidesteps a lot of nuclear’s image problem.
