Project 81 – An Almost Forgotten Standard Nuclear Plant Project

Stone & Webster as well as Sargent & Lundy were just two of the A-E firms that developed and used standard drawings, leading to there being a number of very similar nuclear plants in different places, built for different owners. Some projects, however, were even more repetitive than these.

The push for standardization of all aspects of nuclear plant design and construction led to a number of significant developments in the 1970s.The Atomic Energy Commission (AEC) capped unit size at 1300 MWe, and strongly encouraged standardized NSSS designs that could be referenced in a new plant’s applications for licensing to speed the process. Westinghouse, Babcock & Wilcox, and Combustion Engineering chose to standardize and reference their NSSSs while General Electric decided to standardize and reference the entire nuclear island.

Do you have any insights about how the need to standardize might evolve as reactors get smaller and more dispatchable (i.e., SMRs)?
