Case History #039 REV.04-97

LOCATION: South Ukraine Nuclear Power Plant Unit #1

PROBLEM:
This nuclear power plant had problems with a general leaking of the condenser at the tube to tubesheet joint. Continued sever scaling of the tube internals was causing a steep decline in heat transfer.

SOLUTION:
The unit has 116,000 9 meter, 26mm ID 95/4/1 CuNiFe Tubes and 24 Carbon Steel tubesheets at 25 M2 each. All tubes were to be cleaned and all tubesheets coated.

RESULTS:
This project was completed in April 1991 and has not required repair.
