Construction of the $2.5 billion plant began in 1977.
It was built in accordance with the Standardized Nuclear Unit Power Plan Syndicate (SNUPPS) design. The reactor, a silo-shaped building measuring 205 feet in height and at its base, 150 feet in diameter, sat on a 10-foot thick concrete foundation and was surrounded by walls up to 4 feet thick.
The turbine-generator building, housing four steam turbines and the generator, was 313 feet long and 140 feet high.
Steel piping for the generator cooling water was 13 feet in diameter, and ran a total of 4,320 feet.
