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 [1] and factsheet.[2]

Diagram and specifications for the reactor.

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.

Safety

Accidental overheating.
• 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.

Sabotage
• 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.
