CTSD operations at Concordville grew and ebbed over the near decade of The Concordville Years. At one point (ca 1981/82 per CTSD employee telephone directory), CTSD employment reached a peak level of around 600 people. But financial performance did not support such growth, and there was a major downsizing in the 1985-1987 time frame prior to the relocation to Orlando to be incorporated at Westinghouse Power Generation World Headquarters. Only about 100 CTSD professionals and management remained at the time to make the trip south in the spring of 1987.
