TE 2494904-03 B ESW Pin Hole Leak Page 1of3 Title: Perform Code Case N-513 evaluation to support Operability. ADMINISTRATIVE: This evaluation was prepared in accordance with Exelon procedure CC-AA-309-101, revision 14, Engineering Technical Evaluations. A technical task risk/rigor assessment was performed for this activity in accordance with HU-AA-1212, revision 6. Risk rank was determined to be '1' with a medium consequence (C. 7, Safety System Loss), 1 human performance risk factor (H.10, Group Think), and 1 process risk factor (P.3, Fast Track). Therefore, per table 5.1 of attachment 5 to HU-AA-1212 existing process reviews are adequate. This conclusion was discussed with Jeff Chizever, Manager PEDM on 05/05/2015. impact review per CC-AA-102, revision 28 was performed and it was concluded that procedure revisions are not required. However, the Raw Water Program is impacted by this evaluation. Assignments 2494904-04 and 2494904-05 have been created for the program manager to incorporate any changes into the Raw Water Program. Safety Classification: This evaluation is associated with safety-related equipment and therefore the evaluation is classified as safety-related. This technical evaluation will be submitted to Records Management for retention. REASON FOR EVALUATION/SCOPE: Emergency Service Water (ESW) piping leak was discovered in the Unit 2 Reactor Building Sump room. The leak is directly below the Unit 2 Reactor Building Closed Cooling Water (RBCCW) room floor, upstream of M0-2-33-2972 which is located in the RBCCW room. The leakage was approximately 30 DPM at the time of discovery. The presence of this leak warrants an evaluation in accordance with ASME Code Case N-513-3 (Evaluation Criteria for Temporary Acceptance of Flaws in Moderate Energy Class 2 or 3 Piping, Mandatory Appendix I) in order to allow the associated piping to remain operable until a permanent A S M E S e c t i o n X I C o d e repair can be completed. DETAILED EVALUATION; Engineering has performed an analysis of the areas in accordance with ASME Code Case N-513-3. This piping is 12-inch diameter, 0.375 inch thickness carbon steelpiping,A-106grade Bas shown in Peach Bottom specification M-300 (Piping Materials) and P&ID M-315, sheets 4 and 5 for 33HB class pipe. The design pressure is 150 psig and the design temperature is 100°F. As shown on attached pages 13 and 14, the areas found to be less than the minimum wall thickness value of 0.063 inch are approximately 0. 7 5 inch in the axial and circumferential directions.

TE 2494904-03 B ESW Pin Hole Leak Page 2 of 3 In accordance with CC N-513-3, the pipe circumference at the location of the flaw was examined volumetrically to characterize the length and depth of all flaws in the pipe section. The results of the circumferential examination show that there are no other flaws in the area that are below the minimum wall thickness and need to be considered in this evaluation. Additionally, shear wave UT performed around the area of the flaw verified that there are no crack-like indications present. See the completion remarks for work-order activity C0257348-06 for documentation of this result. Forces, moments, and stresses for the subject piping were extracted from reference between node points 201 and 206. They are shown on pages to 12 of the attachment. The approach to the evaluation methodology included in CC N-513-3 is to compute a static fracture toughness factor, Klc for the circumferential and axial flaw evaluations. For this evaluation, as shown on attached page 2, the value of Klc is 37.111 ksi*in0.5. The evaluation then computes the stress intensification factors, Kl for the circumferential and axial flaws for the various design modes (normal/upset and emergency/faulted) and then compares them to the previously calculated value for Klc. Kl is less than or equal to Klc then the acceptability of the through wall flaw is demonstrated. The following is a summary of the results of the attached CC N-513-3evaluation. Klc = 37.111 ksi*ino.5 Kl Circ. Normal/Upset= 5.036ksi*ino.5 37.111 ksi*ino.5, therefore acceptable. Kl Circ. Erner. /Fault= 4.426 ksi*in0.5 37.111 ksi*in°*5, therefore acceptable. Kl Axial= 7.643ksi*ino.5 37.111 ksi*in°.5, therefore acceptable. For simplification, the maximum safety factor of 2. 7 for Normal/Upset was used in the computation of a 11 Kl Axial, and the maximum safety factors for either the membrane or bending stress was used for the Circ. Normal/Upset and Erner. /Faulted computations. Additionally the subject location was evaluated for the effect of thin wall on the normal piping stress and compared to the established design allowable stress for the piping. In this comparison, the allowable stress of 17, 100 psi for the piping material (A-106, Grade was used. The results of this portion of the analysis, shown on attached pages 5 through 7, demonstrate that a uniform pipe wall thickness of 0.063 inch is acceptable to provide adequate structural integrity for the design basis loadings. CONCLUSIONS/FINDINGS: This evaluation of the discovered min-wall area indicates that the size of the flaw and the surrounding wall thickness is acceptable for continued operation of the associated ESW system piping within the requirements of ASME Code Case N-513-3.
