NuScale small modular reactor
- See also: Nuclear_power_reconsidered
The NuScale small modular reactor is a smaller version of a standard Pressurized Water Reactor (PWR). This article will address the issues raised in the parent article Nuclear power reconsidered. Information is from the company website  and factsheet.
The NuScale Power Module (NPM) is a 250 megawatts thermal (MWt) integral pressurized water reactor (PWR) that employs gravity-driven natural circulation of the primary coolant for both normal operation and shutdown mode. The NPM, including containment, is fully factory-built and shipped to the plant site by truck, rail, or barge.
• In a station blackout condition, the NPM safely shuts down and self-cools indefinitely—with no operator action, AC/DC power, or additional water needed.
• Natural circulation for normal operation eliminates the need for large primary piping and reactor coolant pumps.
• Each NPM houses approximately 5 percent of the nuclear fuel of a conventional 1,000 MWe nuclear reactor.

• NPMs are submerged in a below-grade pool of water housed in a Seismic Category 1, aircraft impact resistant building that serves as the ultimate heat sink for core cooling.
