[global network Roundup] according to Taiwan when the electronic newspaper reported on November 19th, the U.S. National Aeronautics and Space Administration (NASA) has just completed 1 kilowatts (1KW) Mini reactor grade, this month at the beginning of the test, after a successful test will be applied to space and military. According to

reports, the mini reaction furnace called "kW power" (Kilopower), which is named according to its power, it uses a low concentration of solid uranium 235 as fuel (7%), sodium metal recycling heat transfer tube heat exchanger, using high-efficiency Stirling engine engine is converted into electricity and promote exchanges. Because the volume and power are very small, there are not many redundant products after nuclear reaction. Only 0.12% superfluous products can be produced in 15 years, and the radiation pollution is low to negligible.

NASA is working with the U.S. Department of energy, testing will continue until the beginning of 2018, "kilowatt power" will be the first 28 hours of full power test. Lead researcher Mark Gibson (Marc Gibson) said: "we are going to the Nevada Test Center, there will prove the feasibility and safety of this technology, the reactor will give spacecraft Bang, so will be tested in a vacuum chamber, the equipment operating conditions in imitation of space. "Other researchers",

"kilowatts of power Ross ala Moss National Laboratory (LANL) head of Patrick McClure (Patrick McClure) said:" this is the first time we study space for nuclear reactor, reactor space required to provide stable and high power, the spacecraft can operate in Bang no solar conditions, such as the surface of Mars, but also to adapt to extreme conditions. "Lee Mason,

of the energy development unit of NASA's space technology committee, said," we developed a power grid, which is also a better choice for future space missions than nuclear power batteries, "said Li Mason. Nuclear power batteries can only supply hundreds of watts of electricity, but more power is needed to explore mars. I also hope that 'kW power' is just the first step, and that it will evolve into hundreds of kilowatts, or even millions of kilowatts of power systems, to the permanent space base. Tian Ruizhe:
