NuScale completes standard plant design

22 December 2022

The standard plant design - or SPD - provides customers with a generic design for the VOYGR small modular reactor (SMR) nuclear power plant that will serve as a starting point for deploying site-specific designs.

The SPD was completed ahead of schedule and demonstrates NuScale's preparedness for facility construction and equipment procurement and manufacturing of long-lead major engineered equipment, the company said. It encompasses more than 12,000 deliverables to support client-licensing and deployment activities, as well as a "comprehensive 3D model" of the power plant.

Deliverables included in the SPD include full material takeoffs, equipment lists, data sheets, architectural and construction drawings and specifications, detailed system design specifications and calculations, electrical single-lines and load lists, and mechanical piping and instrumentation diagrams.

The NuScale Power Module on which the VOYGR nuclear power plants are based is a pressurised water reactor with all the components for steam generation and heat exchange incorporated into a single 77 MWe unit. It is the first SMR design to receive approval from the US Nuclear Regulatory Commission. The company offers a 12-module VOYGR-12 power plant is capable of generating 924 MWe as well as the four-module VOYGR-4 (308 MWe) and six-module VOYGR-6 (462 MWe) plants and other configurations based on customer needs.

A six-module plant is to be built near Idaho Falls as the Utah Associated Municipal Power Systems-led Carbon Free Power Project, expected to be operational by 2030.
