RC-IPT-0106B is a pressure transmitter that taps off of reactor coolant system hot leg (loop) # 2 . The location of the Pressure transmitter is found in Waterford Unit 3, FSAR Chapter 5.1, Flow Diagram Reactor Coolant System, Figure 5.1-3. The license said that the picture indicates a small amount of boric acid crystals in the area of the leakage. Licensee did not know if the leakage is from a weld, pin hole leak, etc. | RC-IPT-0106B is a pressure transmitter that taps off of reactor coolant system hot leg (loop) # 2 .
