In the mid-1980`s the Tennessee Valley Authority installed plate heat exchangers in the safety-related service water system at the Sequoyah Nuclear Plant. These heat exchangers are compact, they can be assembled in place, they require less flow than more conventional heat exchangers, and they are easily cleaned. However, equations to predict thermal performance are not readily available in the open literature. An analytical model was developed to predict performance of the heat exchangers at off-design conditions and to trend thermal performance. Periodic surveillance tests have been performed and the fouling resistance has been calculated based on these tests and the analytical model. Biological fouling of the plates on the raw water side was determined to be greater than expected due to inadequate biocide treatment of the system.
