SUMMARY
OF CHANGES 2.1 Revised as necessary to remove all gray shading used to identify ITS changes and to delete previous P8L 3.1 and any text identified as CTS. This change is editorial in nature per Step 4.6.4 of IP-SMM-AD-102. (No change bars used)
Revised previous sections/steps as required to comply with new IPEC PT format.
This change is editorial in nature per Step 4.6.14 of IP-SMM-AD-102. (No change bars used) 2.2 2.3 Oeleted previous P&L 2.5, which stated: This test shall be performed by Certified Level I OR Level II examiners. There are no visual examinations performed in this test. (lP2-6354) This change is editorial in nature per Step 4.6.12 of IP-SMM-AD-102. (No change bar used)
Step 4.3.3: Changed reduction in Expected Pump Flow for 2 pump operation to obtain Minimum Expected Pump Flow from 3% to 15%. 15% provides sufficient assurance of flow. The criteria for the corresponding procedures at Unit 3, 3-PT-CS032A 8 6, have been changed to 15% based on the same reasoning.

NO: 2-PT-3YOlO Rev: 2 Page 4 of 17 FLOW TEST FOR UNDERGROUND SERVICE WATER LINE 409 1.0 PURPOSE 1.1 This procedure establishes requirements for demonstrating integrity of the underground portion of Service Water Line 409 (1, 2, 3 header) through performance of a flow test in accordance with ASME Section XI.
This procedure applies to the underground portion of Service Water Line 409.
1.2 2.0 PRECAUTIONS AND. LIMITATIONS 2.1 Precautions and Limitations 2.1.1 This test may be performed when the Service Water System is aligned for either Two or Three Header Operation.
2.1.2 2.1.3 2.1.4 WHEN data is being collected, THEN only two Essential Service Water Pumps (SWP) SHALL be in service.
Proper radiological precautions SHALL be observed when performing this test.
The Service Water Intake Bay is a FME area that requires enhanced controls per IP-SMM-MA-118, Foreign Material Exclusion. The Cognizant Supervisor SHALL conduct a pre-job brief regarding FME controls.
necessary, THEN an RWP SHALL be obtained.
2.2 General Information 2.2.1 2.2.2 2.2.3 Personnel performing this test SHALL read it in its entirety prior to the start of testing.
Test personnel SHALL complete Sections 3.0,4.0, 5.0.6.0, and 7.0, as applicable.
Any discrepancies found SHALL be identified in the Comments, Section 5.0.
2.2.4 This test establishes a flow into underground lines and determines flow out. This is done in lieu of hydrostatic or other VT-2 type types due to IWA-5244 for buried piping systems. WHEN field data has been taken, THEN measured flow is compared with the known flow from pump curve information in order to find the deviation from expectation.

FLOW TEST FOR UNDERGROUND SERVICE WATER LINE 409 1 No: 2-PT-3Y010 Rev:2 I 2.2.5 This test requires that Service Water flow from the Service Water Pumps be obtained using test data and a composite pump curve for two pump operation. The use of a composite curve constructed from manufacturer data and test data is too difficult to arrange in advance for each possible pump variation prior to the test. Therefore, the curve is constructed after the data is obtained. This construction can be expected to take the next working day after field data is obtained.
Apart from this required testing, there are additional evaluations which are routinely made concerning this particular buried pipe. The IST Engineer may elect to provide an overview of current observations and activities in Section 8.1. Some topics for discussion include:
2.2.6 0
The performance of any interior or exterior pipe inspections in support of Generic Letter 89-13. Also, additional examinations of this pipe planned or scheduled in the future.
Inability of the system to maintain flow to loads as specified in station documents.
Unexpected up-welling of water in the Transformer Yard or other locations related to this pipe.
e Any problems with this pipe known or monitored by System Engineering.
The test requires that Service Water flow for the Fan Cooler Units and Emergency Diesel Generators be recorded.
instrumentation is NOT available, THEN alternate instrumentation must be installed or the test can NOT be relied upon to accurately reflect load conditions.
2.2.7 2.2.7.1 WHEN the flow to a particular load is between 1 % and 3% of the expected total flow in two pump operation (Le. between 100 gpm and 300 gpm),
THEN it is permissible to use the last recorded flow if either of the following conditions apply:
Either the flow is maintained by locked valves or the flow is maintained with valves fully open.
IF neither of these conditions can be met, THEN the flow path shall be instrumented in this test. The last recorded flow must come from a controlled source such as a Surveillance Test or Post Work Test. These conditions are evaluated by the IST Engineer in the body of the test.
FLOW TEST FOR UNDERGROUND SERVICE WATER LINE 409 2.2.7.2 NO: 2-PT-3Y010 Rev: 2 Page 6 of 17 WHEN the flow to a particular load is less than 1 % of the expected total flow in two pump operation (i.e. less than 100 gpm), THEN it is permissible to use the expected design flow provided by the System Engineer for that load.
IF this flow is a range, THEN the minimum flow SHALL be used since that is the consewatwe flow in this case. These conditions are evaluated by the IST Engineer in the body of the test.
2.2.8 2.2.9 This test SHALL be performed by Certified Level I or Level II examiners.
Test equipment may be installed in advance of the procedure step requiring installation.

Evaluation to Determine Expected SW Flow During Surveillance Test PT-3Y10 Flow Test for Underground Service Water Line 409 The pumps in service for the test were 21 SWP (97JC 1705s) and 23SWP (97JC 1704s).
Per PT3Y10, the recorded river water level during the test was 6 feet 8 inches below the centerline of the pump discharge pipe. An overall distance of 9 feet was used for the difference between river level and strainer gauges.
Per PT3Y 10, the 2 1 SWP discharge pressure (PI-1 193) was 97 psig, and the 23 S WP discharge pressure (PI-118 1) was 95 psig.
The discharge pressure in feet is; 21 SWP: 2.3 1 X 97 psig - 224 ft 23 SWP: 2.31 X 95 psig-219 ft The total lift is; 21 SWP: 224 ft + 9 feet = 233 ft 23 SWP: 219 ft + 9 feet = 228 ft The flow data around the test point:
21 SWP: 4232 gpm at 242.32 ft and 4606 gpm at 220.68 ft 374 gpm 121.64 f = 17.28 gpdft[233 ft -220.68 ft =12.32 ft ; 12.32 ft x 17.28 g p d f t
-213 gpm ; 4606 gpm -213 gpm = 4393 gpm]
Interpolated Flow = 4393 gpm 23 SWP: 4606 gpm at 233.56 ft and 4842 gpm at 227.16 ft 236 gpm 16.4 ft = 36.9 gpdft E228 ft -227.16 fi = 0.84 ft ; 0.84 ft x 36.9 gpdft = 31 gpm ; 4842 gpm - 3 1 gpm = 481 1 gpm]
Interpolated Flow is 4811 gpm Total SW flow is 4393 gpm + 481 1 gpm = 9204 gpm Acceptance criteria is to be within 15% of estimated pump flow. The acceptance criteria is:
