 can operate for ~15 years without need for refueling |

| ● | HALEU:    SOLO                                                                      
 can operate for ~70 years without need for refueling. As of today, certain non-fuel 
 materials would need to be replaced at ~45 years                                    |

| (1) | Based on the neutronics analysis, with                                                          
 the use of HALEU, SOLO could either (i) operate at a large power output of 20MWt for            
 15-years, or (ii) operate at the same power output of 4MWt for ~70 years. Increasing            
 the power output, however, would require a change to the design of the reactor, while operating 
 at the same power for a longer period of time would not require such design changes.            |

SOLO can also benefit from current and future accident tolerant fuel (ATF) solutions related to new clad material, which would allow an increase of the average working temperature, consequently improving the thermodynamic efficiency and possibly extending its industrial applications Fuel Rods/Moderator The fuel rods contain UO 2Pellets at 4.95% U-235 enrichment level in Zircalloy clad (same as operating Light Water Reactors). The moderator is a made of a solid heterogeneous Beryllium and Graphite matrix. 54 Coolant SOLO is Helium cooled. The coolant, which is helium gas, enters the bottom of the reactor, is heated while passing through dedicated channels adjacent to the fuel rods and collected into the upper plenum. Keeping a physical separation between the coolant and the fuel rods is a very important design feature. After being heated, the helium moves from the upper plenum to a heat exchanger transferring the heat to the secondary circuit for the production of electricity. Multiple Redundant Shutdown Mechanisms The reactor is controlled when everything is operating normally using 12 control blades. It is built with a N+4 redundancy: 8 out of 12 blades are sufficient to shut down the reactor. In addition to the control system, we built 4 different active and passive redundant shutdown mechanisms; each of which has its own redundancy. These 4 shutdown systems can be relied upon in case of malfunction or incident:

| ● | 12 shutdown blades:                            
 8 of which are enough to shut down the reactor |

| ● | 12 shutdown drums,                             
 6 of which are enough to shut down the reactor |

| ● | 6 shutdown pellets,                            
 2 of which
