, 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 Pellets
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.

Fuel

SOLO can use today’s technologies but
is compatible with future technologies without having to make any significant changes to the design.

SOLO provides the only platform to be able
to transition from currently licensed fuel products (LEU) to future fuel products and supply (HALEU):

| ● | LEU:    SOLO                                         
 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

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
