USA approves 4th generation nuclear molten salt reactor Hermes 2

Approval has been given for Hermes 2

Nuclear energy capacity 2050 operating in the US state of Tennessee, which wants to triple its size by 2020 Kairos Powerplays an important role in this transformation. The company aims to produce safer, more efficient and environmentally friendly energy by using molten salt technology. Hermes reactors developed by the company, 4th generation nuclear reactor One of the latest examples of technology. This technology both provides high fuel efficiency and increases safety by minimizing leakage risks.

However, Kairos Power’s nuclear power plant design features gravel-bed Hermes reactors with graphite moderators containing fluoride salt as the coolant. Inside the reactor, three structural ISOtropic (randomly packed) in pebble form (TRISO) when using particle fuel approx. 20 percent enriched low level uranium Contains (HALEU).

Hermes 2 will produce 20MWe of electricity

In December 2023, Kairos Power received approval from the NRC to build the Hermes Low-Power Demonstration Reactor (Hermes 1), the first fourth-generation reactor to receive construction approval in the United States, and started construction in recent months. This reactor is being built solely to demonstrate system integration and operational safety. The facility will not produce energy.

With the final approval, the NRC has given Kairos permission to build a power plant that will eventually power the grid. The power plant, called Hermes 2, will be located next to Hermes 1 and 20 MWe It will have two 35 MWth reactors with combined production capacity. Not only did Kairos manage to get approval from the NRC for Hermes 2, but they did it in 16 months. NRC also wants to simplify regulatory approvals for future projects.
