A project to build a first-of-its-kind nuclear reactor in eastern Idaho has been significantly downsized cutting in half the number of small modular reactors (SMR) from 12 to 6, but boosting the amount of power produced by the installation of six SMRs from 300 MWe to 462 MWe.
The change in the power output results from a change to the design of the NuScale SMR from 50 MWe to 77 MWe. NuScale submitted the 50 MWe design to the NRC for licensing and the revised power rating will likely be a follow on action.
Downsizing the project in terms of the number of SMRs built for the first of a kind installation reduces the project’s overall costs (12 units to 6) and the amount of power it can produce (600 MWe to 472 MWe). The Post Register reported that the energy cost that project partners will pay rose from $55 per megawatt-hour to $58 per megawatt-hour.

Space travel beyond our moon will require a huge shift in space propulsion.
That s partly because quicker flights mean crews are exposed to less radiation during the journey.
A couple of ideas are in the works to achieve that: nuclear thermal propulsion and ion propulsion.
The future of human space exploration, such as visiting our moon or even Mars, could be essential for upcoming generations. But despite that and the recent renewed interest in space travel thanks to companies like SpaceX, humans traveling beyond our moon will require a paradigm shift in space propulsion.
