SUMMARY
OF PROBLEM EVALUATION REPORT 154477 The hydrology issues at Watts Bar Nuclear Plant are being tracked through a single Problem Evaluation Report (PER), PER 154477. PER 154477 was initially written to address the assumptions made on Tellico Dam with respect to stability during the Operating Basis Earthquake. As other issues were identified during the hydrology analysis input reconstitution, additional PERs were written to address the specific issue and to address operability and functionality of that issue. As these additional PERs were closed, they were added to PER 154477 as the single tracking document. Currently, the open corrective actions remaining for PER 154477 are for documentation corrections.
Upon completion of the hydrology analysis for probable maximum flood (PMF), one of the additional PERs, PER 211722, was written to address the higher than original licensed PMF level (0.7 feet increase). Equipment required for flood mode was evaluated for impact of the increased PMF level. The review concluded that all equipment was adequate for the PMF event with margin except for the Unit 1 Thermal Barrier Booster (TBB) Pump motors. The base of these motors is located within 1/4 of the revised design basis flood level inside the structures.
The Unit 2 pumps are at the same elevation as the Unit 1 pumps. Since these components have reduced margin, a Unit 1 temporary alteration control measure was implemented to provide protection around the equipment through the use of a barrier. This protection is implemented as part of the flood mode preparations as described in Abnormal Operating procedures. The barrier is not required to deem the pump motors functional but is recommended to provide assurance of additional margin. Unit 2 is implementing a permanent design change to protect the pump motors.
To date, the only issue identified in the additional PERs is protection of the TBB pump motors as described above.
