Work Begins on the First US Gen IV Nuclear Reactor.

This reactor is not being designed to produce electricity, but rather energy higher up on the thermodynamic chain, and thus more flexible in potential use, that is, heat.

Work begins on first US Gen IV reactor

Subtitle:

Kairos Power has announced the start of site work and excavation for the Hermes Low-Power Demonstration Reactor, the first non-light-water reactor to be permitted in the USA in over 50 years.

Excerpts:

Hermes is a non-power version of Kairos Power's fluoride salt-cooled high temperature reactor, the KP-HFR and is the first and only Gen IV reactor to date to be approved for construction by the US Nuclear Regulatory Commission (NRC). Targeted to be operational by 2027, the reactor will be the company's first nuclear build, and is a critical step on the company's iterative path to commercialising advanced reactor technology. Its primary objective will be to demonstrate the ability to produce affordable nuclear heat, but it will not produce electricity: that will come in the next iteration, the proposed Hermes 2 plant.

Kairos Power has contracted with heavy-civil construction company Barnard Construction Company, Inc for the work at the Hermes site in Oak Ridge, Tennessee. At the same time, the companies are also collaborating to build the third Engineering Test Unit (ETU 3.0), a non-nuclear demonstration facility co-located with Hermes that will generate supply chain, construction, and operational experience to inform the Hermes project. This iterative approach will allow lessons learned from ETU 3.0 civil construction to transfer seamlessly to the Hermes facility, the company said...

...Both Hermes and ETU 3.0 will be built using modular construction techniques, with reactor modules fabricated in Kairos Power's facility in Albuquerque, New Mexico, which will be shipped to Oak Ridge for assembly. This will demonstrate the potential of a factory-built small modular reactor design to transform conventional nuclear construction, the company said...

...The NRC issued a construction permit for Hermes last December. Kairos Power has also applied for a construction permit for the electricity-generating Hermes 2 test reactor, which will also be built at Oak Ridge and will feature two 35 MWt units similar to the Hermes plant. Earlier this month, the regulator announced the completion of its final safety evaluation for the Hermes 2 construction application, finishing its review of the design nearly four months ahead of schedule and using about 60% fewer resources than expected, thanks to lessons learned from its earlier review of the Hermes plant.

Any and all developments in nuclear energy, which is the only available effective tool against extreme global heating now being observed while we all wait for the grand so called "renewable energy" adventure that did not come, is not here and won't come, come under the general rubric of "too little, too late." Nevertheless this development is doing something as opposed to doing nothing about extreme global warming.

1. Wonderful!

Safe, clean nuclear fission is the only viable way forward. Nothing else is capable of replacing dirty energy. Thank you so much for sharing this!

2. Ahead of schedule and under budget -- how often do you hear that, in any field ? nt

3. We are going to see a lot of this in the future. The Biden administration has done a wonderful job behind the...

...scenes encouraging the revivifying of our nuclear intellectual infrastructure, as well, in some cases, the manufacturing infrastructure.

Our national laboratories have been heavily involved; my son, I'm pleased to say is working closely with one such national lab.
