      Former engineers from SpaceX are working on a portable microreactor that is lightweight and cost-effect. They call it the “world’s first portable, zero-emissions power source.”
     The microreactor project was originally intended to be a develop a power source for a Martian colony. The group of engineers decided that Earth needed it more. They founded a company named Radiant to continue work on the microreactor for terrestrial applications. It could provide instant power to hard-to-reach places and quick installation in populated areas.
     John Gehin is the Chief Scientist at the Nuclear Science & Technology Directorate at the Idaho National Laboratory (INL). He issued a statement that read “In some areas of the world, reliance on diesel fuel is untenable, and solar and wind power are either unavailable or impractical. Clean, safe nuclear microreactors are emerging as the best alternative for these environments. Unlike diesel generators, it doesn’t require frequent fuel deliveries, since the fuel in the portable microreactor can last more than four years.”
     Battelle Energy Alliance is the contractor that manages operations at the INL. They are collaborating with Radiant on the microreactor project.
     Home generators emit more pollutants that trucks and industry combined. They also pose a more significant risk to human health. This is because they are located in or near a home and run for long periods. Engineers and startups are searching for low-cost, portable solutions to replace current home generators. Possibilities include solar-powered batteries being used in Nigeria, microgrids in a box, or hybrid solutions that could maintain local power during grid outages.
     Radiant’s portable microreactor could provide a clean solution to a range of power challenges. The portable microreactor is better for the environment without compromising on performance. In addition, it is small enough to fit in a shipping container.
      The microreactor could be deployed to remote regions where fossil-fuel generators would ordinarily be employed. Unlike diesel generators, it does not require frequent fuel deliveries. The fuel in a portable microreactor can last more than four years.
      Doug Bernauer is the co-founder of Radiant. He recently said, “The nuclear industry can benefit greatly from aerospace technologies and software developments that have occurred over the past 20 years, and have not made their way into nuclear.”
      Bernauer was researching energy sources for a possible Martian colony when he realized that there was a need for the same kind of flexible, economical power source right here on Earth. He was motivated to team up with two other former SpaceX engineers and co-found Radiant.
    The Radiant portable microreactor will produce over one megawatt. This would be enough electricity to power about one thousand homes for up to eight years. A group of microreactors could power a small town. The microreactors use an improved fuel that can withstand higher temperatures than most nuclear fuels and does not melt which allows for safer operation.
     Radiant is among many public and private organizations that are working on compact nuclear reactors. However, to date, none have been able to develop a truly compact, economical and long-lasting portable microreactor.

     Slovenské elektrárne, a.s. (SE) is an electric utility company based in Bratislava, Slovak Republic, and is the successor to the former state monopoly. It operates nuclear, hydroelectric and fossil fuel power plants in the Slovak Republic.
     SE said that over the past weekend, there were successful start up tests and the launch of steam turbines for the new Unit 3 reactor at the Mochovce nuclear power plant. It was connected to the Slovak power grid for the first time at twenty percent of its nominal power at 11 PM on the 31st of January.
     Branislav Strýček is the Chairman and CEO of Slovak Power Plants. He said, “Today represents a fundamental milestone for SE, the community of nuclear energy workers and the entire country. As of today, the third unit converts the thermal energy released in the reactor into electricity. This will help us fulfill the agreement with the government, in which SE undertook to supply cheap electricity for households at a price of EUR61.2077 euros (USD66.7) per megawatt hour, which represents an unprecedentedly low price of electricity for households within the EU. The new block will significantly contribute not only to energy stability, but also to the commitment to reduce greenhouse gas emissions on the road to carbon neutrality.”
     During the energy start-up process, tests have been carried out at increasing power levels – five percent, fifteen percent and twenty percent – of the reactor’s nominal power. The company said, “After successfully preparing and carrying out the tests necessary for the start of the turbines, over the weekend, steam was brought into them for the first time, which gradually spun them up to the nominal speed – 3000 revolutions per minute.”
     Tests were also carried out on the generator itself, the block transformer and the four hundred kilovolts line connecting the plant to the Slovak electricity system. “After completing this part of the power start-up, Slovenské elektrárne could proceed to the actual phasing of the first turbogenerator to the network at 20% of the nominal power of the reactor and the third unit … began supplying the first electricity to the network.”
     The next stage of the launch process will be to test the reactor at levels from thirty five percent to one hundred percent. The final step is the successful completion of a one hundred and forty four hour trial run at the full four hundred and seventy one megawatt output.
     Martin Mráz is the director of the Mochovce plant. He said that in the coming weeks, “the new unit will supply electricity to the grid with short-term planned shutdowns, according to the new unit commissioning schedule”.
     Construction of the first two four hundred and seventy-one megawatt VVER units at the four-unit Mochovce plant began in 1982. Work started on Units 3 and 4 in 1986, however it stalled in 1992. Units 1 and 2 were completed and came online in 1998 and 1999 respectively. A project to complete Units 3 and 4 started in 2009. Unit 4’s schedule has been to follow about one or two years behind work on Unit 3. Each of these reactors will be able to provide about thirteen percent of Slovakia’s electricity needs when operating at full capacity.
     The final design includes many upgrades for safety and security. These include aircraft impact protection and emergency management measures based on lessons learned from the Fukushima disaster which were incorporated during the project. The Slovak Nuclear Regulatory Authority issued the final authorization for commissioning Unit 3 of the Mochovce nuclear power plant in August of this year. The service life of the new reactor is expected to be about sixty years.
