After removing insulation and pressurizing the service water line 12b it was discovered that there is a pinhole leak at weld 8297. This weld is located on a 3.5 inch 0.D. pipe on a service water return branch line which connects 10 inch line 12b to the 31 FCU internal coils. 5.2 Purpose This calculation determines the minimum wall thickness for the 3.5 inch branch connection and evaluates the allowable flaw size {axial and circumferential) for this section of pipe. 5.3 Method of analysis The method of analysis is based on EN-CS-S-008-MULTI, Rev. 1, utilizing an Excel spreadsheet to calculate and tabulate the appropriate required values. Pipe stress inputs are extracted from IP3-CALC-SWS-03023 which inspected a weld on the same branch connection as part of 3R10 outage 89-13 inspections.

5.4 Assumptions

Conservatively, the plant-wide standard observed wear rate= 0.012 in/yr is used. This calculation investigates a stainless steel component where the wear rate will be slower than that of carbon steel piping. Inaccessible areas assumed to have thickness consistent with available readings which are all at or above nominal thickness due to the relative consistency of results. Note: only actual UT readings are utilized in this calculation, including tabulation of average thicknesses.

Calculation IP3-CALC-SWS-03023 Rev. 1 IP-CALC-16-00079 0/b 5. 7 Calculation Based on the design temperature, pressure, and material condition, an allowable stress value for the piping material was obtained.

Pipe stresses from normal, upset and emergency loading conditions are either determined in this calculation or are obtained from other calculations for the component system. Some of the stress values obtained from existing calculations and various reference information are in Attachment

2. The calculated wall thickness for hoop stress, axial pipe stress are then determined and compared to 30% of the nominal pipe wall thickness and the highest value of the three will be used as the minimum required wall thickness for the design condition of the pipe at that location.

5.8 Conclusion/Results The minimum required thickness for the elbow containing weld B297 is 0.073 inches, whereas the minimum measured thickness is 0.117 inches. The maximum allowable axial flaw size is 4.11 inches and maximum allowable circumferential flaw size is 3.65 inches. The existing flaw is characteriseq as approximately 0.50 in x 0.50 in, and the uninspected arc length (approximately 3 in) of the pipe circumference is less than the allowable circumferential flaw length. Therefore, if the entirety of the uninspected portion of the pipe were to be considered a flaw, the pipe would still retain its structural integrity as evaluated in this calculation.

The pinhole flaw is opposite the uninspected portion and the flaw sizes of the two areas are independent and not additive.

Based on the above statements, the pipe is structurally adequate for service until a permanent repair can be made during the upcoming 3R19 outage in 2017.

For regions of piping designed to specific wall thickness requirements, such as counterbores or weld attachments.

(3) For the small end of reducers, the standard shall be based on the loom of the pipe size at the small end. For the large end, the large end transition and the conical portion, it shall be based on the loom of the pipe size at the larger end. (4) The formula is applicable for straight pipes, bends, and elbows. For reducers, tm1n at each end shall be equal to l.nin of straight pipe of the same nominal size as the reducer end. For the conical portion and transition at larger end of reducers, tm1n shall be that of the large diameter pipe end. For branch connections and tees, the reinforcement area of the opening shall be based on the 831.1 code. (5) t" min can be obtained by the "Trial and Error" method until the "Allowable Stress -Axial Stress" due to Normal, Upset, Emergency, and combined Normal and Thermal Expansion conditions are all positive and one of them shall be close to zero. (6) (I) can be calculated from Appendix D of ANSI 831.1. (i') needs to be adjusted for the pipe wall thinning.

It is suggested that the average thickness or 2 times of the original value be used for the i' calculation.
