Qn June 4, 1998, with Unit 1 in Mode 5, plant personnel performing Generic Letter 89-13 ("Service Water System Problems Affecting Safety Related Systems" ) inspections made a preliminary determination that the West Containment Spray (CTS) heat exchanger had been installed 180 degrees from the design position. The service water inlet appears to be aligned to the outlet side of the heat exchanger, which results in the impingement plate being located on the service water outlet side. The impingement plate is designed to be located on the inlet side to prevent sand and silt from impinging on the heat exchanger tubes and causing erosion of the tubes. This condition was determined to be a potentially unanalyzed condition, and an ENS notiTication was made at 0850 hours0.00984 days <br />0.236 hours <br />0.00141 weeks <br />3.23425e-4 months <br /> EDT under 10CFR50.72(b)(2)(I). This LER is submitted in accordance with 10CFR50.73(a)(2)(ii), for an unanalyzed condition.

Independent verification of the heat exchanger orientation will be performed in mid-July by site Quality Control. If it is confirmed that the impingement plate is located on the outlet side of the heat exchanger instead of the inlet side, visual inspection of the tubes'utside surface and eddy current testing of select tubes in the vicinity of the inlet nozzle will be performed. These inspections will determine the presence and extent of tube degradation.

Review of previous inspection records indicates that the remaining CTS heat exchangers are installed correctly. This will be confirmed by inspection prior to start up of the units.

As the eddy current testing has not yet been scheduled, a tentative date for updating this LER has been set for September 30, 1998. The update may be provided earlier, depending on the testing schedule and the results.
