WNP-2 was the only unit of the five that was completed and put into operation. WNP-3 and WNP-5 are located on 1,600 acres (650 ha) on the Satsop Site near Elma in Grays Harbor County, Washington. Today the site hosts the Satsop Business Park and the Overstock.com Call Center.
Not sure if this is still accurate, but definitely know that they never actually finished or started up these reactors and now it's a generic business park. So it at least has some sort of precedent, even though this isn't exactly the same as having the facilities generating power for the business.
