The original steam generators from Virginia Power and Electric Company's (VEPCO) Surry 2 plant were replaced after approximately 6 years of service. One of these generators was subsequently transported to the Hanford Reservation in Eastern Washington, where it is now housed in a specially constructed research facility. The generator, a Westinghouse model 51F has drilled hole carbon steel support plates, a creviced tube sheet, and unsensitized Inconel 600 tubing. The unit operated for the first year using phosphate secondary side water chemistry, then was changed to all volatile treatment (AVT). Condensers were tubed in 90:10 CuNi, and experienced leakage. The plant was cooled by water from the James River, which is brackish. At the time of removal approx. 22% of the generator's tubes had been plugged, mainly because of severe denting. The first two rows were plugged following an in-service U-bend failure. 17 figs.
