 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 are enough to shut down the reactor |

| ● | If those three                                                                              
 systems fail, a mechanism injecting helium 3 into the reactor can be activated to shut down 
 the system                                                                                  |

Monolith: Biological Shield

SOLO is encased in all sides by the 2.5m thick
concrete block, the Monolith, serves as a biological shield from radiation and the decay heat removal system. With the Monolith, decay
heat is removed by natural convection. Because almost non-existent radiation reaches the outside of the Monolith, we expect that an EPZ
will be limited to its operation boundary. That means you can build a SOLO anywhere and allow humans to walk right up to it.

Competitive Strengths

Unique Technology and Safety Features

SOLO has been purposefully engineered as a
compact 4MWt/1MWe reactor to prioritize safety. Its low thermal power output eliminates the risk of core meltdown. By using helium as
a coolant instead of water, SOLO also avoids the danger of hydrogen explosions. Additionally, helium’s inert nature means it doesn’t
become radioactive under neutron exposure, unlike alternatives like water or carbon dioxide, reducing proliferation concerns. The reactor
is equipped with multiple independent shutdown mechanisms (control blades, shutdown blades, drums, pellets, and helium-3 injection) and
enclosed within the Monolith, allowing it to operate without the need for an EPZ and ensuring robust safety and regulatory compliance.
