The lube oil pipe extends approximately 8" from the heat exchanger that is rigidly supported.
The natural frequency of the lube oil pipe should be in the rigid range, above 33 Hz. The jacket water cooler pipe extends downward approximately 18" from the HX piping, slightly less rigid than the lube oil pipe because of the two couplings.
The two heat exchangers and the EDG are on the same foundation.
The seismic displacement for the two pipes during postulated occurrence of a seismic event should be of very small magnitude due to their rigid behavior.
The jacket water pipe will rotate slightly at the coupler to give way to accommodate the displacement of the lube oil pipe. The seismic interaction will not be an adverse one.2. The angle iron is rigidly supported with approximately 6" cantilever length and there are no sharp edges. During a seismic event, the tubing will vibrate and rub against the flat surface of the angle iron for 20 seconds or so. For such a small mass and short period of time, there will be no adverse seismic interaction between the tubing and the angle iron as the forces developed at the interface will be very small.EN-DC-168 REV 0 Engineering Report No. IP-RPT-12-00039, Rev. 0, Page F-23 of 55 ATTACHMENT

Con-trolled longitudinal bending of the pipe within acceptable limits can be accommodated by PVC pipe itself Longitudinal deviation of the pipeline can be accommodated through either joint offset or axial flexure (curving) of the pipe. Curving of PVC pipe may increase the possibility of failures during tapping under pressure.
Whenever prac-ticable, taps should be made on the inside radius of longitudinally bent pipe.Permissible joint offset may be significant when gasketed joints that are designed for such a purpose are provided on the PVC pipe. Depending on pipe size and joint design, the offset per joint for gasketed PVC pipe joints in the unstressed condi-tion varies from approximately 1/3 to 5*. Available joint offset is dependent upon inser-tion depth of the spigot. Assembly should be made only to the mark provided."Homed" or over-inserted assemblies allow for no flexibility.
Some manufacturers encourage joint offset only for accommodation of laying water pipe not to grade, with fittings to be used for known changes in direction.
Joint offset limits should be obtained from the manufacturer for joints that are to be stressed to the permissible limit without leakage.Mathematical relationships for the longitudinal bending of pressurized tubes have been derived by Reissner.
These relationships compare favorably to those of Timoshenko and others. One critical limit to bending of PVC pipe is long-term flexural stress. Axial bending also causes a very small amount of ovalization or diametric deflection of the pipe.AWWA PVC pipe has short-term strengths of 7,000-8,000 psi (48.26-65.16 MPa)in tension and 11,000-45,000 psi (75.84-403.42 MPa) in flexure. The long-term strength of PVC pipe in either tension, compression, or flexure can conservatively be assumed to equal the hydrostatic design basis HDB of 4,000 psi (27.58 MPa). Applying a 2.5:1 safety factor results in an allowable long-term tensile or flexural stress equal to the recommended hydrostatic stress S of 1,600 psi (11.03 MPa) for AWWA C900 PVC pipe at 73.4'F (23°C). The 2:1 safety factor used for AWWA C905 PVC pipe sim-ilarly yields a hydrostatic stress of 2,000 psi (.13.79 MPa). However, the bending of PVC pipe barrels larger than 12 in. (300 mm) is usually not recommended because of the forces required.
Either the 1,600 psi (11.03 MPa) or 2,000 psi (13.79 MPa) figure may be used for the allowable long-term flexural stress in gasketed joint pipe that is free of longitudinal stress from internal pressure longitudinal thrust. However, when the joints are restrained as in solvent cementing, without snaking the pipe in the trench, then the end thrust from internal pressure imposes a longitudinal tensile stress equal to one-half of the hoop stress.The equation for allowable bending stress Sb is Sb = (HDB-St)-T (4-13)Where: HDB hydrostatic design basis of PVC pipe, psi [4,000 psi (27.58 MPa) for AWWA C900 and C9051 S, = HDB/2 = tensile stress from longitudinal thrust, psi T' = temperature rating factor (see Table 5-1)SF = safety factor (2.5 or 2.0 as applicable)
NOTE: The longitudinal stress from thermal expansion and contraction can be ignored in buried gasketed joint piping because of relaxation of the soil restraint over the length between joints. When determining bending limits, longitudinal thermal stresses should be considered in restrained pipes, such as lines with solvent-cemented joints and restrained and supported piping.Copyright

The two bottom panels beneath cobicle 1M, 2M, 3M and 4M/4MC have no screws on them.There is no adverse seismic interaction because the panels can only be disloged and moved R1 toward the exterior panel.3. Housekeeping issue: Two loose padlocks were found on the ledge but were removed by the operator.4. The West side exterior panel has mild surface corrosion.
- 5. The bottom ledge has mild surface corrosion.
- 6. All the anchor bolts have mild surface corrosion.
- 7. Inside the top panels, the contact screws have slight surface corrosion.

CR-IP3-2013-01644 was generated.
The following condition were observed: (1) Two carts near the HP desk by the entrance should have their wheels blocked/choked to prevent movement during a seismic event. These carts are not near safety related equipment currently but should have their wheels choked in accordance with IP-SMM-DC-910.
(2) Inside the compartment above cubicle 9RC, an inside partition panel (approximately 6" wide by 10" high) is missing two screws on the right side. This panel is held in place by one screw and one inserted tab on the left side. The inserted tab and the remaining screw on the panel are structurally capable to hold the panel in place during a seismic event because the panel is light. Though the partition panel is opened up with an observable gap, it cannot interact with anything nearby.(3) The two exterior side panels of the MCC have missing screws. One top screw of a side panel is missing 1 out of 16 screws. For the other side panel, one bottom screw is missing out of 16. Even though there is one screw missing on each panel, the panel is judged to be supported adequately by the remaining 15 bolts during a seismic event because the weight of the panel is small when compared to the combined capacity of the 15 screws.(4) The hinged vertical wire way exterior panel (on the south side of MCC) adjacent to cubicle I OFJ and IOFM is missing one of the two screws. The one remaining screw on the panel and the hinge are structurally capable to hold the panel in place during a seismic event because the panel is light.(5) The hinged vertical wire way exterior panel (on the south side of MCC) adjacent to cubicle I OFC has one screw with a broken pin and can fall off The hinge and the other remaining screw on the panel are structurally capable to hold the panel in place during a seismic event because the panel is light.(6) In the bottom of the MCC, with the bottom panels removed, there are pieces of tie wraps, two fuses and tape lying inside. This is just a house keeping issue.

Compartment 3G cover and compartment directly above 6K on panel 39MCC are missing two screws out of four. The covers are held with two screws which are judged to be sufficient since the compartment covers are small.Cable tray immediately in front of 39MCC had cables with broken zip ties (the cables were not tied to the cable tray). However, the cables are adequately placed inside the tray and will not dislodge during a seismic event. This is judged to be acceptable.
See additional comments below.Comments (Additional pages may be added as necessary)
The following conditions were observed but none of them are structurally significant.
The cover panels were found to have missing screws. There is no operability concern because the weight of each panel is fairly light and the remaining screws have sufficient capacity to support the panel during a design basis earthquake.
CR-IP3-2013-01788 and WR-302229 were generated.

Comments (Additional pages may be added as necessary)
Note: Bus 2A was inspected pre-outage on 2/1912013 while Bus 5A was inspected during 3R17 on 3/18/2013.
CR-IP3-2013-00675 and WR 299488 was created.For Bus 2A only: 1. Inside the fuse panel on row 32 (above the spare EC 16500), there is a fuse block lying on the shelf of the cubicle. The horizontal seismic acceleration is low and the weight of the fuse block is minimal. Assuming the fuse block will move under inertial effects, there will be very low energy and no adverse seismic interaction is expected.
Nevertheless, the fuse block should be removed.2. Inside cubicle 52JLT IN, there is a loose nut on the concrete floor below the breaker rack.This is a housekeeping issue only.3. On row 33, the cubicle above cubicle MCC33, a fuse block (with no fuse) is lying on the shelf of the cubicle. The horizontal seismic acceleration is low and the weight of the fuse block is minimal. Assuming the fuse block will move under inertial effects, there will be very low energy and no adverse seismic interaction is expected.
Nevertheless, the fuse block should be R1 removed.4. On row 34, inside the first cubicle from top (above 52-2A cubicle), one of the two connectors providing support for a wire way is missing. Since the wire way with the wires inside is fairly ligh and the horizontal seismic acceleration is low, the seismic and normal forces acting on the connector will be minimal. One connector is judged to be adequate from a seismic perspective.
Nevertheless, the missing connector should be replaced.5. In the back of the Switchgear 31, there is an upper and lower panel on row 31. Both panels are missing one out of six screws. Since the horizontal seismic acceleration is low, the five existing screws will be structurally adequate.
Nevertheless, the missing screw should be re-installed.
For Bus 5A only: 1. Fuse blocks are lying on the shelf of the upper cubicles because the Switchgear is being serviced.

CR-IP3-2013-00765 was created for the following condition.
For Bus 3A side: Inside the fuse panel on row 7 (above 3A T6A), a control fuse block for tie breaker Bus 6A to 3A was pulled out and found lying on the shelf of the cubicle. The operator said that the IP3 SOP requires the fuse block be placed on the shelf in contradiction with the IP2 procedure which requires rotating the fuse block 180 degrees and re-inserted into the slot to show the fuse in "off" position.
The horizontal seismic acceleration is low and the weight of the fuse block is minimal. Assuming the fuse block will move under inertial effects, there will be very low energy and no adverse seismic interaction is expected.For Bus 6A side: Inside the fuse panel on row 10, the fuse block for SWP33 was pulled out and found lying on the shelf of the cubicle. This is similar to the issue found on Bus 3A side. The horizontal seismic acceleration is low and the weight of the fuse block is minimal. Assuming the fuse block will move under inertial effects, there will be very R1 low energy and no adverse seismic interaction is expected.CR-IP3-2013-00767 is created for the following condition.
WR-299868 was generated.
- 1. On row 8, inside cubicle for 6A relays, the plastic clip for the wire was detached from the wall of the metal compartment because the glue was dried out. A few instances were observed.
The horizontal seismic acceleration is low and the weight of the wire is minimal. Assuming the wire will move under inertial effects, there will be very low energy, insignificant displacement and no adverse seismic interaction is expected.2. There is a loose rivet at the door hinge for the 35FCU cubicle. WR# 00147781 was found on the door.3. On row 14, inside the upper most cubicle, one of the two connectors providing support for a wire way is missing. Since the wire way with the wires inside is fairly light and the horizontal seismic acceleration is low, the seismic and normal forces acting on the connector will be minimal. One connector is judged to be adequate from a seismic perspective, 4. 3 cover panels for the Station Transformer
- 6 have missing screws: The front panel is missing 2 out of 10 screws. Two back panels are missing 1 out of 10 screws. Since the horizontal seismic acceleration is low, the remaining eight screws will be structurally adequate 5. 3 cover panels for the Station Transformer
