The SW pipe with the hole is connected to the discharge of Component Cooling Water (CCW) heat exchanger No. 21. In order to mitigatethe adverse effects of the hole in the piping, a clamp is being installed to seal the pipe (Ref. 8.1).This calculation will evaluate the impact of the clamp weight on the Component Cooling Water saltwater piping stress, pipe support loads, and heat exchanger nozzle loads. Additionally, the loads onthe piping and supports are evaluated for thrust loads that would occur in the event of a pipeseparation at the location of the leak. This calculation does not evaluate the local stress on thepiping due to the installation of pipe clamp. That evaluation will be completed in ILD-CALC-0014 (Ref. 8.4). ILD-CALC-0014 will use the piping forces and moments from this evaluation to determine the acceptability of the clamp design. This calculation is safety related.2.0 Design Input2.1 The model input for all existing piping and the applicable stress results are taken fromCCNPP Calculation M-93-038 Rev. 1 (Ref. 8.2). A review of the outstanding calculation comments on M-93-038 Sheet 6 was completed, and it was verified that there is no impacton this analysis. Also, a review of existing calculation change notices against M-93-038 wasperformed. There is no impact on this calculation, In the thermal stress analysis (Eqn.13/14) defined by TEA (thermal evaluation analysis control word) in the M-93-038 input, theload case SEISDB was not excluded. The thermal analysis shouldn't include seismic loadsand therefore, has been excluded from the TEA input for correctness. Since this analysisdoes not change any thermal cases, there is no affect on the analysis. 2.2 The salt water cooling piping layout and node numbers are given on CCNPP Drawing 91374Sheet 1 (Ref. 8.3)2.3 The pipe clamp assembly weight is approximately 233.7 lbs per CCNPP Calculation CA08093Rev. 0 (Ref. 8.1 Attachment E). Therefore, the use of 240 lbs in the ME101 model will bebounding. 2.4 The piping code of record for the CCW salt water piping is USAS B31.1 1967 (Ref. 8.5).2.5 Pipe supports SK-42075 and SK-42076 have a minimum margin of 20% using loads 15%greater than those given in M-93-038 per CCNPP Calculation CA00700 (Ref. 8.6) andCA00702 (Ref. 8.7). The design basis calculations for these supports are C-93-058 (Ref. 8.14)and C-93-059 (Ref. 8.15).2.6 Pipe Support 5K-42073 has a minimum load ratio of 0,89 for the south-side base plate boltinteraction per CCNPP calculation C-93-056 (Ref. 8.16). The support was analyzed with adesign load of +/-11,000 lbs in the x-direction, 1,500 lbs in the positive y-direction, and 4,710lbs in the negative y-direction. The loads were qualified using faulted loads comparedagainst normal load allowables. A review of the as-built modifications for this support (Ref.8.17 through 8.20) was performed, and there is negligible affect on this analysis. 2.7 Per Ref. 8.1, the through-wall leak Is located on 12" diameter class U-1 piping. Theoperating pressure of U1 piping is 35 psig per Piping Class Summary Sheet M-601 (Ref. 8.9).Page 4 of 24 ILD-CALC-0013 REV 0Job #1002-0040 Per Piping Class Sheet M-600 (Ref. 8.10), the piping is standard weight. The internal area ofstandard 12" pipe is 0.7854 ftW per Crane Technical Paper No. 410 (Ref. 8.11) when using thenominal wall thickness. 2.8 Correspondence with CCNPP plant personnel indicates that the maximum flow rate throughthe salt water piping is 7,000 gpm (see Attachment G).2.9 The maximum density of salt water of salt water is 64.1 Ibm/ft3 per ASME PTC 12.2 AppendixI (Ref. 8.12). Using a larger density corresponding to a temperature less than typicaloperating temperatures is more conservative. The density assumes normal salinity of seawater (see Section 3.3).3.0 Assumptions 3.1 The pipe clamp weight is added as a single mass to node point 290 (Ref. 8.3). Per Ref. 8.1,the installed clamp CG will be approximately 13 inches downstream of valve 2-CV-5206, Node 290 is 5 inches downstream of the centerline of the valve and between 0.5 and 1.5inches downstream of the valve flange. The next closest node is node 286, which is 38inches downstream of the valve centerline. Node 290 is sufficiently close to the actualclamp mounting location to approximate any stress induced on the piping by the installation of the pipe clamp. Additionally, since node 290 has an assigned SIF of 1.3 and the clamp isinstalled on a straight run of pipe (no additional SIF) the calculated stress is conservative atthis location. 3.2 In order to model the event of a full circumferential pipe break, a two inch dummy elementwas added between Node 286 and 290 for the pipe separation model (Attachment C). Thiselement was given a low stiffness (modulus of elasticity of 1 psi) to allow the ends of thepiping created by the "break" to move independently. This dummy element has no impacton the pipe loads or movement. It only serves to connect the piping upstream of the breakto the remaining piping of the model.3.3 The salinity of the salt water in the piping is assumed to be of normal concentration. This isa reasonable assumption since CCNPP salt water is taken from the Chesapeake Bay and nota high-salinity source.3.4 Only supports near the clamp are evaluated for this analysis since they will bear the vastmajority of load induced on the system by the clamp and postulated break. The remaining pipe supports are deemed acceptable by judgment due to their relatively distant proximity.

• Support SK-42076 Is nearest to the installation location of the clamp. This support's restraint direction is in the global Y-direction.
• Support SK-42075 Is the nearest support with restraint in the global Z-direction.

Italso provides support in the global Y-direction.

• Support SK-42073 is the nearest support with restraint in the global X-direction.

Italso provides support in the global Y-direction. Page S of 24 ILD-CALC-0013 REV 0Job #1002-0040 4.0 Methodology and Acceptance CriteriaCCNPP Calculation M-93-038 Rev. I (Ref. 8.2) is the calculation of record for the Unit 2 CCW systemsalt water piping. M-93-038 uses the Bechtel-developed software ME101 (see Section 5.0) tocalculate the code stresses and support loads in accordance with the CCNPP code of record for thispiping, USAS 831.1 1967 (see Section 2.4).4.1 Benchmark Calculation M-93-038 only gives the maximum computed stresses in the salt water piping.Therefore, the exact input used previously will be rerun to determine the loads and stresses atnode 290 for comparison purposes. The benchmark ME101 input file (ILD-CALC-0013 RO BM.inp) is in Attachment A.4.2 Pipe Clamp Installation In order to evaluate the impact that the added weight of the pipe clamp has on the pipingsystem, a weight of 240 lbs is added to node 290 (Assumption 3.1 and Design Input 2.3). Noother changes are made to the model. The results are compared against those in thebenchmark model to determine how the clamp affects pipe stresses and support loads. TheME101 input file (ILD-CALC-0013 ROCLAMP.inp) for the pipe clamp installation is inAttachment B.4.3 Pipe Separation A third model was developed to postulate pipe movements should the salt water piping havea circumferential break at node.290. In order to do this, a dummy element with low stiffness was added in between Nodes 286 and 290 (see Section 3.2). On each end of the dummyelement, an axial thrust load is imposed to account for loads induced by the salt water flowingfrom the break. The ME101 input file for the pipe separation case is in Attachment C (ILD-CALC-0013_ROS.inp). The two axial thrust loads are oriented in the model such that their actions serve to push thepiping apart at the break, simulating the thrust of salt water leaving the system in the event ofa break. Per Ref. 8.8, the thrust load due to the blowdown of a fluid jet can be calculated fromthe conservation of momentum as follows:T = 144(AE)(Po -P.) + pV2AE Equation 1Where: T = Thrust Load (Ibs)AE = Area of the Pipe Opening (ft2)P, = Stagnation Pressure of the Liquid (psi)Pý = Atmospheric Pressure (psi)Page 6 of 24 ILD-CALC-0013 REV 0Job #1002-0040 p = Density of the Fluid (Ibm/ft3)V = Velocity of the Fluid (ft/sec)4.4 Acceptance Criteria4.4.1 Pipe StressThe results of the analysis are considered acceptable if the calculated pipe stress isless than the given allowable. The pipe stress allowables for A53 Gr B Welded(material for node 290) and A377 GR 30 are as follows:Table 4-1 -USAS 831.1 1967 Allowable Stresses (A53 GR B Welded)ALLOWABLE STRESSDESIGN (PSI)CONDITION LEVELSUSTAINED LOADS 1.0 x SH 12,700EQN. 11OCCASIONAL LOADS B 1.2 x SH 15,240EQN. 12OCCASIONAL LOADS D 2.4 x SH 30,480EQN. 12THERMALEXPANSION 1.0 x SA 19,050EQN. 13Page 7 of 24 ILD-CALC-0013 REV 0Job #1002-0040 Table 4-2 -USAS B31.1 1967 Allowable Stresses (A377 GR 30)DESIGN ALLOWABLE STRESSDESPSI)CONDITION LEVELSUSTAINED LOADS 1.0 x SH 3,000EQN. 11OCCASIONAL LOADS B 1.2 x SH 3,600EQN. 12OCCASIONAL LOADS D 2.4 x SH 4,800"EQN. 12THERMALEXPANSION 1.0 x SA 19,050EQN. 13*Per M-93-038 page 13 Note 2, Sy for Gray Cast Iron Gr. 30 is notavailable, so pipe stresses are compared with SH/0.625 = 4,800 psi.4.4.2 Pipe SupportsPer Refs. 8.6 and 8.7, the nearest pipe supports (SK-42076 and SK-42075) have aminimum of 20% margin when using loads 15% greater than given in Ref. 8.2 (seeSection 2.5). Therefore, if the loads due to the added weight of the clamp systemincrease less than 20%, then they will be acceptable by inspection. If the loadincreases are greater, the supports will need to be evaluated in more detail. If thetwo closest supports' load increases are acceptable, then the supports further awayare deemed acceptable by judgment (Assumption 3.4).The closest support that restrains the piping in the X-direction is SK-42073. Thecomponents with the least margin in support SK-42073 are the South-side base platebolts. Their maximum interaction ratio is 0.89 (ratio of tension to allowable plusratio of shear to allowable). The load ratios for all other components in the supportare much less. The maximum design load for this support is +/-11,000 lbs in the x-direction, 1,500 lbs in the positive y-direction, and 4,710 lbs in the negative y-direction (Ref. 8.16). If the load increases are bound by the maximum analyzeddesign loads, then the results are acceptable. 4.4.3 Heat Exchanger NozzleThe CCW Heat Exchanger nozzle loads were evaluated in M-93-038 Attachment 11and 14. Since it has been shown that the nozzle loads are acceptable at those levels,Page 8 of 24 ILD-CALC-0013 REV 0Job # 1002-0040 if the results of this analysis give loads less than the previously evaluated loads, thenthe nozzle is acceptable.

The software input was developed at ILD's Baton Rouge offices and run onCCNPP's computers. CCNPP maintains ME101 as safety related under their Quality Assurance Program. ME101 was validated under CCNPP calculation CA04657 Rev. 6 (Ref. 8.13). The programinput and output are as specified in Sections 4.0 and 6.0. The output files contain the date the inputfile was run, and therefore, that date applies to the corresponding input file as well.

The movements for SK-42076 increased more significantly. A review of Ref.8.15 indicates that the design of this pipe support allows free movement in the pipe's axialdirection (Global Z). Additionally, there is a 0.5 inch gap on either side of the pipe in theGlobal X-direction. Since all displacements in the X-direction are less than 0.5", thesemovements are acceptable. With the exception of the loads for SK-42073 and the Maximum Faulted load for SK-42076, the load increases are less than 20%. In the case of the Maximum Faulted load for SK-42076, the load is negative and less than the Minimum Faulted load, and therefore bounded by theacceptance criteria. Per Section 4.4, these loads are acceptable. For support SK-42073, the loads in the y-direction remain within previously analyzed valuesand are acceptable. The maximum x-direction load is -12,707 lbs which is greater than theprevious maximum analyzed load of 11,000 lbs. Increasing the bolt interaction load ratio(Design Input 2.6) by the ratio of load increase to design load:(-12,707)/(-11,000)*0.89 = 1.028 > 1.0However per Ref. 8.16, the support was analyzed using faulted loads compared against normalload allowables. Additionally, conservatisms exist in both this analysis and the originalsupport analysis. If the faulted allowables were used and conservatisms

removed, the boltsare acceptable by inspection.

The HX 21 outlet nozzle loads (absolute value) for the piping with the clamp installed are givenin Table 6-25. All loads are less than the originally analyzed loads in Table 4-3.Page 22 of 24 ILD-CALC-0013 REV 0Job #1002-0040 Table 6-25 -CCW Heat Exchanger Outlet Nozzle Loads at Node 350 (Pipe Separation) Load Force (ibs) Moment (ft-ibs)Case Fx Fy Fz Mx My MzNorm 9,200 2,984 0 371 2 24,469Upset 9,716 3,410 516 1,964 2,072 26,879Faulted 10,095 3,783 895 3,133 3,513 28,977The magnitude of pipe separation in the event of a circumferential break is calculated fromthe resultant displacement between nodes 287 and 288 under normal sustained loadconditions. The resultant movement is approximately 9/64" and will be easily encapsulated by the length of the clamp.Table 6-26 -Resultant Pipe Movement Due to Circumferential BreakDisplacement (in)Node DX DY DZ Resultant 287 -0,024 0.000 0.000 0.134288 -0.004 -0.132 -0.0037.0 Conclusion This evaluation determined the acceptability of installing a pipe clamp around a through wall leak inCCNPP Unit 2 CCW salt water piping with regard to pipe stress, pipe support loads, and nozzle loads.All pipe stresses are within allowables. Pipe support load increases are bounded by the existingmargin. Nozzle loads due to pipe separation and clamp installation are less than the loads originally used to qualify the nozzles. Additionally, the pipe clamp is large enough to entirely encapsulate thepiping movement in the event of a full circumferential break in the piping at the location of the leak.Therefore, there is no adverse impact due to the clamp installation on the piping system.8.0 References 8.1 ECP-13-000947 Rev. 08.2 CCNPP Calculation M-93-038 Rev. 1, "Component Cooling Pump Room Piping -Unit 2"8.3 CCNPP Drawing 91374 Sheet 1 Rev. 18, "Component Cooling Water Pump Room Piping -Salt Water Cooling System -Unit 2"8.4 ILD-CALC-0014 Rev. 0, "Evaluation of 12-U-1-2001 Line Enclosure" 8.5 Calvert Cliffs Engineering Standard ES-040 Rev. 00, "Piping Design Criteria" 8.6 CCNPP Calculation CA00700 Rev. 0, "Modification to Pipe Supports Associated with SaltWater Piping System"Page 23 of 24 ILD-CALC-0013 REV 0Job #1002-0040 8.7 CCNPP Calculation CA00702 Rev. 0, "Evaluation of Pipe Supports for Salt Water PipingSystem due to Minor Deviation from Design Condition and/or Proximity to AdjacentAnchor Bolts"8.8 Moody, F.J.; "Prediction of Blowdown Thrust and Jet Forces;" ASME 19698.9 Calvert Cliffs M-601 Piping Class Summary Sheets Rev. 498.10 Calvert Cliffs M-600 Piping Class Sheets Rev. 768.11 Crane Technical Paper No. 410, "Flow of Fluids Through Valves, Fittings, and Pipe,"Reprinted 20068.12 ASME PTC 12.2-2010, "Steam Surface Condensers" 8.13 CCNPP Calculation CA04657 Rev. 6, "Accepts Version N9 on Individual LAN computers

The determining factor as towhether Patch type 1 or Patch 2 will be used is the ability of the neoprene tape toseal the hole. If the hole is too big, the force of air rushing from the hole will preventthe installation of Patch type 1. In those instances, Patch type 2 should be used.MATERIALS:

1. Neoprene tape2. Hose clamp.INSTALLATION GUIDELINES:

1. INSTALL neoprene tape at hole location,

2. WHEN air leak is contained, THEN INSTALL and tighten a hoseclamp over the hole location.
