Los Alamos National Laboratory together with one of the leading US electrical companies Westinghouse Electric will create a new nuclear portable microreactor that can be moved with one truck.
In the US, create a portable nuclear microreactor
The possibilities of using such a reactor are virtually endless - from space programs to use in humanitarian missions to supply people with heat and electricity, informs enovosty.com/news.
Andy Erison, Deputy Director for Global Security at the Los Alamos Laboratory, on Thursday published an article where he spoke about the merits of the designed reactor and revealed details about the principles of its operation.
According to him, the microreactor is safer than conventional nuclear reactors. For example, unlike the reactor at the Fukushima-1 nuclear power plant, it has a better cooling system. Instead of pumps that supply cooling water to the reactor, it uses special heat pipes, which, by evaporation and condensation, effectively remove heat from the reactor.

To control the reaction in the core, “passive regulation systems” are used instead of graphite rods. At the Chernobyl nuclear power plant, the rods did not perform well, Erison notes (quotes Sputnuk).
He stated that the microreactor can produce 1 megawatt of power over ten years. This is enough to fully provide electricity from 1,500 to 4,000 consumers.
Arson recalled that currently the most compact reactor is considered to be a heterogeneous energy loop reactor (EGP-6). In total, there were four such reactors in the Soviet Union, and all of them were installed at the Bilibino NPP. A feature of such reactors is the natural circulation of the coolant - saturated steam in the channels of the core with thermal neutrons. The channels of the reactor are placed in a graphite stack.

The Los Alamos microreactor with EGP-6 has nothing in common. This is a product of the developments of NASA, designed to solve the problem of energy in space. NASA has experience in creating nuclear energy in confined spaces. Thermoelectric generators use the heat generated during the decay reaction to power the Voyager and Galileo apparatuses.
Arson noted that NASA has long been studying the possibility of using uranium-235 to generate electricity from a self-sustaining nuclear chain reaction, which can be done with less effort than a conventional reaction in standard reactors. Uranium-235 should become the “heart” of the microreactor. Tests conducted earlier this year showed that a 6-inch piece of uranium-235 can produce 4 kW of power. Passive safety systems are used to control the reaction.
Further, Erison says that the military is very interested in the development of a microreactor in the United States. Aspects of adaptation of the device to the needs of the sun is engaged in Westinghouse. The main parameters of the reactor should be mobility and ease of use. It is expected that the reactor can be installed and run anywhere in the world within 72 hours. According to the plans, the first microreactors will be ready for deployment in the next five years.
