1. PURPOSE The purpose of this document is to provide an inventory of the embedded piping, buried piping, and penetrations that will remain in the end state structures (i.e., below 588 foot elevation) at the Zion Nuclear Power Station (ZNPS). The document provides a basis for the estimated lengths and diameters, and also estimates the surface areas and void spaces associated with them. The document also provides the current planned end state (e.g., pipe removed from penetration or pipe remains in penetration). Penetrations along with elevation and reference drawings for the Unit 1 and 2 Containments, Auxiliary Building, Spent Fuel Building, Turbine Building and Crib House, Tendon Tunnels, Main Steam Tunnels, and the Waste Water Treatment Facility WWTF are summarized in Attachments A thru E. A final list if all piping and penetrations with estimated lengths, surface areas, and void space is provided in Attachment F.

2. DEFINITIONS Embedded Pipe - A pipe that is encased in concrete and that runs vertically through a concrete wall or horizontally through a concrete floor and is contained within a given building.

Buried Pipe - A pipe that runs through soil is defined as a buried pipe.

Pipe Penetration - A pipe (or remaining pipe sleeve, if the pipe is removed, or concrete, if the pipe and pipe sleeve is removed) that runs through a concrete wall and/or floor, between two buildings, and is open at the wall or floor surface of each building. A penetration could also be a pipe that runs through a concrete wall and/or floor and opens to a building on one end and the outside ground on the other end.

3. DISCUSSION 3.1. General Void Space Volume and Surface Area Method The use of the inside versus outside diameter varies depending on whether or not the piping is embedded and cannot be removed but will left in place and surveyed. If the piping is removed the outer diameter is used unless it is through a larger sleeve, in which case the inside diameter of the sleeve is used. The equation used for the inside surface area is Equation 1.

Equation 1 - Surface Area of Opening

= 2 Where r = the pipe radius used (inner or outer as described above) or the sleeve radius used.

h = pipe length in same units as r.

The equation for the void space volume is Equation 2.

Equation 2 - Void Space Volume of Opening

=

3.2. Preliminary MARSSIM Classification A preliminary MARSSIM Classification was assigned to the piping and penetrations evaluated in this document. This classification was based upon knowledge of Pressurized Water Reactor systems and system contamination levels at Zion. Class 1 systems are those that have a high probability of a Page 7 of 123

TSD 14-016 Revision 0 Derived Concentration Guideline Level concentration being exceeded. The systems are those that contained high activity water, such as Waste Discharge lines, Spent Fuel Pool, fill drain and clean-up lines, Residual Heat Removal lines, etc. Class 2 MARSSSIM lines are those that have a 50%

probability of exceeding a DCGL. These are generally secondary systems with the potential for cross contamination from primary system to secondary system leaks, such as Component Cooling, Main Steam, Feedwater, etc. Class 3 systems have a less than 50% chance of exceeding a DCGL. These are generally secondary systems with very low probabilities of significant cross contamination due to the volumes of the systems and potential decrees of cross contamination, such as Fire Protection, Primary Water, Demineralized Water, Station Air, Instrument Air, etc.

4. CALCULATIONS 4.1. Containment Penetrations and Embedded Piping As noted in TSD 13-005 (1) and TSD 13-006 (2) the current plan is to remove all concrete inside the liners of the containment except for the incore sump area and access tunnel. This will minimize the amount of embedded piping remaining in the end state such that penetrations will make up the bulk of the surface area.

Unit 1 and Unit 2 containment penetrations are provided in drawings Unit 1 M-281, M-282 and Unit 2 M-661, M-662. As seen in Attachments A and B, the penetrations are located in three areas in the containment walls, the east and west Main Steam Tunnels and the Unit 1 north and Unit 2 south penetrations into the Auxiliary Building pipe chases as seen in Figure 1. Current plans are to remove piping from these penetrations leaving only the sleeves.

Figure 1 - Overall Layout of Containment Penetrations The penetrations and through wall piping are identical in both Unit 1 and Unit 2. The penetrations and the length and diameters of the penetrations with and without the piping (i.e., Open Sleeve) are provided in Attachment F and G.

There are also penetrations where the pipe will remain in the penetration (Pipe in Sleeve). As seen in Figure 1, each containment also has a penetration for the fuel transfer tube connecting the lower Page 8 of 123

TSD 14-016 Revision 0 cavity to the Fuel Handling Building Transfer Canal. Current plans are to leave the piping in place for these penetrations. The ends in the Containment up ender pit have blank flanges welded on as part of the cavity isolation preparations for internal segmentation. Since the end state requires all metals other than those embedded in concrete to me removed (3), it is anticipated that the pipes will be cut flush with the walls and open in the end state.

The length of the transfer tube piping in each unit is shown as 8 2.5 (e.g., 98.5 inches) in drawing B-213 Detail 4. With 24 inch OD and a 0.688 inch wall thickness the pipe ID is 22.624 inches. The void space volume is 39,597 cubic inches or 22.92 cubic feet (0.65 m3). The surface area is 48.62 ft2 or 4.52 m2.

Figure 2 -Penetration P-49 Fuel Transfer Tube Length from B-213 Detail 4 As seen in Figure 3, there are also three Recirculating Sump Suction lines and two Cavity Flood Sump Suction lines that connect to the Auxiliary Building. The pipes are planned to remain in their sleeves. All five pipes are 20 inch pipes with 24 inch sleeves embedded in the concrete below the liner at the 561.25 foot elevation. One Recirculation Sump line is a spare that is capped at the Auxiliary Building penetration. The estimated lengths are approximately 50 feet as seen in Figure 3. The wall thickness of the 20 inch pipe is 0.594 inches making the inside diameter 18.812 inches. Although each pipe varies slightly in length the interior surface area is approximately 252 ft2 (23.41 m2) and 98.7 ft3 (2.80 m3).

TSD 14-016 Revision 0 Figure 3 - Unit 1 Recirculation Sump and Cavity Flood Sump Piping Each Unit 1 Cavity Flood Sump and Recirculation Sump pipes estimated length, surface area, and void space volume is provided in Table 1. The corresponding Unit 2 penetrations in Attachment F are P323, P324, P235, P236, and P237. The horizontal runs under the Containment 565 liner floor level are at the 5613 elevation making the top of the 24 inch diameter pipes at the 5623 elevation which is 29 below the end state liner floor level.

Containment Incore Area Embedded Piping There is also a 1 1/2 pipe embedded in the concrete of the Incore Access Tunnel P125 for Unit 1 and P325 for Unit 2 on Attachment F. The incore area extends below the containment slab and consists of a cylindrical area directly under the reactor vessel biological shield and a sloped tunnel. The incore area walls are 1 foot 11.5 inches thick (23.5 inches) with a 2 foot 6 inches under vessel area floor. There is also an access tunnel with 15 inch thick walls, floor and roof. The sump is shown on drawing B-234 as being 2x 2x 2 at about 1 from the from the bend line. The pipe enters the wall about a floor above the sump making the opposite of the triangle 17+9-36 or 226 as seen in Figure 4. The base is 433 - 309 or 126 making the hypotenuse length 25.74 assuming the pipe enters the wall for about a foot before sloping up results in an estimated length of 26.74.

Main Steam and Tendon Tunnel Aerated Drain Piping The tendon access tunnel galleries also contains a sump that has trace levels of contamination in sump water and sludge samples as well as trace levels of removable contamination. The Main Steam Tunnel floor drains also drain to this sump. There are 4 Aerated drains embedded in the tendon gallery access tunnel and Main Steam Tunnel floors. The Tendon Tunnel runs under the periphery of the Containment as shown in Figure 5 and has a floor elevation of 565-9-76 or 5486.As seen in Attachment D and Attachment E excerpted from drawings B-466, B-477, B-484, and B-487 the Main Steam Tunnel and Tendon Tunnel aerated drains are connected and drain to a common sump in the tendon tunnel. The Unit 1 drawings are shown on B-466 and B-467. The Unit 2 pipes are shown on B-481 and B-487. All of the pipes have a 4.5 inch outer diameter and 4.026 inch inner diameter. The penetrations are comprised of floor drains and clean out ports in the Mains Steam Tunnel that connect to a common header pipe. Attachment D shows M1 is a drain at 5696 1/2 to a bend beneath the floor. As seen on B-484 M1 drops to the 569 which is 0.54 feet. The pipe then makes a 45 degree run to the main drain line. As seen on B-466 the clean out port is 84 -2 thick wall or 64 from the wall. The 45 degree section is thus the hypotenuse of a 64 45 degree triangle or 8.96 feet. At Cleanout port M2 the pipe makes a 45 degree bend from the 569 to the 5687 or a 5 x 5 45 degree triangle which is 0.59 feet. The length of the run at 569 elevation between the 45 degree section is 48-64-5-6 from the wall or 353. As seen in Table 5. The Unit 2 drain M201 has slightly different lengths due to different elevations.

TSD 14-016 Revision 0 Total 124.52 As seen on Figure 8, Figure 13, Figure 14, and Figure 17, Unit 1 has a 2 inch oil line A42 ODO-100-2 that remains near the 573 elevation. The 2 inch oil line is at the 5694 at match line R. As seen in Figure 13 the pipe runs horizontally from R to where it makes a vertical rise to the 5722 elevation near the 45 degree bend in the SI pipe. Figure 13 and Figure 17 show the length is 1+39+159 or 206. Along this length, the pipe slopes upward from 5684 to 5688 but this does not significantly affect the length. The vertical rise is 5722-5698 or 26. From the 26 vertical it continues west the length to match line S is25-159 to X 25 to 49-3 or 19 past X for a total length of 36 feet. As seen on Figure 17 the pipe slopes upward from 5722 to 5736 over the length past X for a 14 rise which results in a length of 36.02 feet. The line then continues south toward the tank and slopes vertically from the 5736 elevation to the 576 elevation or 26 over the length which is 151-65 or 88 to the center of the tank. With the 26 rise this is 9.02 to the center of the tank. Assuming the pipe from the wall to the tank is removed during the excavation and removal of the tank this is a length of about 46 feet.

TSD 14-016 Revision 0 The Unit 1 Service Water line is a 2-inch diameter line and with a layout parallel to the Unit 1 Station Airline 1SA-012-1 1/2 in Table 28. The Unit 1 Station Air line A44 1SA-014-1 1/2 is shown on Figure 20. The Service Water line travels the same 186 distance to the vertical. The exceptions are that the elevation at R is 5707 and the vertical rise is also to the 584 elevation making that segment 135. The length to the bend into the building is 18 shorter than the station air line at 458 versus 472. The distance north to the penetration in the floor is the slightly greater because the penetration is further from column 23 at 39+110+14+11+9+9 or 9/6 to Column 23 versus 84 for the Station Air. The penetration is 16 past column 23 for a total length of 11. same but the remaining height of the vertical segment is 4 feet rather than 5 feet since the elevation is 584 versus 583.

The Unit 1 Instrument Air line A46 OIA0-004-1 1/2 is shown on Figure 20. The Instrument Air line travels the same 186 distance to the vertical. The elevation at R is 5707 the same as the Service Water and the vertical rise is to the 584 elevation making that segment 135 as well. The length to the bend into the building is 9 longer than the service water line at 465 versus 458. The distance north to the penetration in the floor is the 8 further as seen in Figure 8 making the length 118. The remaining height of the vertical segment is the same at 4 feet since the 584 elevation is the same. The pipe section lengths are summarized in Table 30.

2. As explained in the text above Figure 8, the line is identified at Column 24 match line S as 1SF-017-2 and labeled as Demin Water indicating it was a clean water supply to the spent fuel pool. As seen Figure 21 line changes designation from 1DW012-2 to 1SF17-2 at valve 1SF0004 on drawing M-63. The M-69 shows the DW system and the start of that line and references the M-63 drawing for continuation. The M-63 drawing references the M-69 drawing and shows the SF system along with the 1SF0004 valve and the beginning of the 1SF017-2 line.

Figure 21 - Excerpt from M-63 Showing 1SF-017-2" is Demin Water Supply The label on M-107 SH 1 indicates the lines is at the 5834 1/2 elevation. The penetration elevation at R is 5707 resulting in a vertical of 129 1/2. The length to the vertical is the same at 186. The length west from the vertical to bend north is 9 shorter to the floor penetration than the Fire Protection line at 442. The penetration at R is 9 closer to column 23 than the Fire Protection line resulting in the north segment to the floor penetration being 96. The vertical segment toward the floor penetration is longer going from 583 4 1/2to the 588 or 4 7 1/2. The pipe segment lengths are summarized in Table 32.

These lines are A48 1SF-008-2, A47 1SF-022-3, and A40 1AD-146-4. M-63 shows A48 1SF-008-2to be a Refueling Water Storage Tank line and A47 1SF-022-3 to be a Fuel Pool Demineralizer line indicating they are Class 1 lines. It is 186 to the vertical for both A48 1SF-008-2and A47 1SF-022-3. Both lines are at the 5694 elevation at match line R making the vertical length to 583 138 long. Both lines the travel west parallel to the Fuel Handling Building slab. The distance to match line S is again 25-149 or 103. It is 25 to X with an additional 39 for 1SF-022-3 and 46 for 1SF-008-2 past X to the bend north. The total length of the west segments from the vertical to the bend is 39 for 1SF-022-3 and 399 for 1SF-008-2. The distance of the penetrations at R from column 23 is shown in Figure 8 for 1SF-022-3 it is 39+14+1 or 61. 1SF-008-2 is 16 further south or 77. M-107 SH 2 shows the distance from column 23 south to floor penetrations in 16 for both pipes leading to lengths of 91 for 1SF-022-3 and 83 for 1SF-008-2 to the vertical segment through the slab. Each pipes vertical segment is from 583 to 588 or 5 feet. The line segment lengths are summarized in Table 33.

It travels the same 186 distance to the vertical and has the same vertical length of 138 to the 583 elevation. Like the other lines, it bends south between S and X. The distance from vertical to match line S is25-149 or 103. The distance to from X to the bend is noted as 3+39 or 69 with another 9 to the line for 76 which give a length from S to the bend of 25-76 or 176. The total length to the bend is 103+176 or 279. As seen on Figure 8 A66 is 39+310+9+9+9 from Column 17 or 910. It is 149 to the pipe from Column 19 with a 26 distance from columns 19 to 17 this is 113 this plus the 910 to column 17 is 211. From there it turns west again and parallels the foundation which extends to just past match line U. Piping past the foundation is assumed to be buried pipe that will be removed. It is 149 to X then 25 to U then 39 to the end of the foundation for a total length of .436 The remaining line past the foundation will be removed.

It runs next to 2SA-012-1 1/2 whose segment lengths are shown in Table 34. The length to the vertical is 186. As seen in Figure 8, the penetration is at the 5707 Figure 20 shows the elevation of the vertical at 584 making the length 135. The pipe then runs west to where it bends north. The distance west is 9 less than 2SA-012-1 1/2 length or 27. The penetration at R is 39+110+14+11+9+9 or 96 to column 17. The additional length is26-149 or 113 for a total length of 209 feet. It then proceeds west 69 to match line X and 25-26 or 226 for a total length of 293. The distance from the bend south to the penetration is 149+2 or 169.

There is a 2DW-014-3 and a 2DW-008-3. There appears to be incorrect labeling of the lines on M-107 Sheet 2 as seen in Figure 22 since 2DW-014-3 and 2DW-008-3 cannot be the same line and have two different penetrations at R21 in Figure 8.

TSD 14-016 Revision 0 Figure 22 - Unit 2 Pipe ID Labeling Change on M-107 Sheet 2 Therefore, the lines segment lengths will be assigned to the 2DW-014-3 and 2DW-008-3 as shown in Figure 22. Both lines run parallel to 2AD-146-4. Both are 186 to the vertical. 2DW-014-3 is at the 5707 elevation at match line R and 2DW-008-3 is at the 5694 elevation as shown on Figure 8. They are both assumed to be at the 583 elevation as indicated in Figure 13 which shows two 3 lines at K1-K1. This results in a vertical rise length of 125 for A63 2DW-014-3 and 138 for A61 2DW-008-3. The 2DW-008-3 segment west from the vertical rise to the bend south is 9 shorter than 2AD-146-4 at 263. 2DW-104-3 is an additional 9 shorter at 256. As seen in Figure 8, 2DW-014-3 is 9 closer to column 17 that 2AD-146-4 or 20 2DW-008-3 is 39+17+9+16+9+9 or 91 with an addition 26-149 from column 17 this makes the length 204. From the bends, south the lines turn west for a length where 2DW-014-3 is 9 shorter than 2AD-146-4 or 286. 2DW-008-3 is 9 shorter than 2DW-014-3 or 279. The length south to the vertical leading to the floor penetration is the same as 2AD-146-4 or 169. The vertical to the 588 foot elevation is 5 feet.

The Containment Sump piping at M-16 and M-24 in Figure 3 are also attributed to the Containment. The next penetration is a 14 inch sleeve through the 2 foot thick wall between the Aux Building and a Main Steam Tunnel at the 571 elevation as seen on Attachment B near row H column 10. There is a similar sleeve on the opposite wall at H30. As seen on Attachment B, there is a 10 inch Fire Protection Line OFP-12-10 at H10 that is shown on Drawing M-165 and M-187. Near G10 there are two OSW-008-12 lines as seen on drawing M-185 and Attachments A & B.

As seen on Attachment A and B there are many penetrations along the wall at Row G between the Turbine Building and Auxiliary Building. All penetrations labeled as open sleeve are assumed to have the pipe removed, leaving an opening equal to the outer diameter of the pipe. Attachment B shows penetrations at G13 consisting of a 3 waste disposal line OWD-31-3 from Drawing M-165 and M-171.

There are two 12 Service Water Supply lines to the Diesel Generator Heat Exchangers at J9 A27, A28 and J31 A30, A31as seen on Attachments A and B. As seen in Figure 27, these lines pass under the steam tunnels for 21 feet, then under the tunnel floor towards G for 143 and 1`23 plus the 219 of H to G. Detail C of M-106 (provided as Figure 28) shows an elevation change from 554 9 and 5534 at G to 567 6at J. This is an additional 142 and 129 making the total lengths of the lines 71 2 and 69 9 or 837 and 833 inches respectively. As seen in Figure 28, the horizontal runs under the Main Steam Tunnel are at 5636, the floor is at 570 so the pipes are 66 below the floor in the fill material below the slab. The horizontal run under the Diesel Generator floor are at the same elevation with the floor at the 5676. The pipes horizontal runs are 4 feet below the floor. Thus, none of the horizontal runs of A27, A28, A30, or A31 are with 8 of the surface of any floor.

As shown on Figure 39 excerpted from M-103 and M-104 the pipes run east 104 beneath the 560 floor from G to A through the Turbine Page 42 of 123

TSD 14-016 Revision 0 Building slab where they exit the Turbine Building Oil Room wall at A19 and A21 at 5498 as seen in Figure 38. Figure 48 shows that they exit the Turbine Building slab 6 feet before match line A. Thus, the distance from G to the slab exit is 171.5 feet as seen on Figure 39. They then travel 8 feet east to the pipes center line of the vertical rise. They then rise vertically from 5498 to the 579 elevation (i.e., 294) making the buried pipe length 37 4. The pipes continue eastward to the Crib House wall as seen on M-106 and Figure 48. As seen in Figure 38 and Figure 37, the horizontal sections traversing from the Turbine Building to the Crip House at the 579 will be cut and removed leaving the buried vertical sections. Drawing M-105 shows the lines traversing east where they pass through the Crib House wall at AA19 and AA21. M-106 and Figure 38 shows it is 2 feet from the center line of the pipe to A. M-105 shows the distance from A to AA as 50 feet for a total of 52 feet that will be removed. M-106 and M-105 shows the Crib House wall to be 4 feet as seen in Figure 48.

Figure 33 - Unit 1 South Diesel Oil Penetrations Page 47 of 123

TSD 14-016 Revision 0 These are routed through the 18 thick wall between the Diesel Generator and Turbine Building in 8 sleeves. M-104 shows 3 8 sleeves between G32 and G35. The pipes will be removed leaving the 8 sleeve openings.

As seen in Figure 27 there is also a 14 diameter sleeve passing through the Diesel Generator Building and Steam Tunnel walls between H&J at columns 10 and 31 (T34b, T34a). As seen on Attachments A and B the walls are 2 feet thick.

The 16 Service Water Return lines T32 and T33 from the Diesel Generator Heat Exchangers are also embedded below the Diesel Generator Building floors as seen in Figure 27. These connect to the 48 Service Water Supply Header on Drawing M-103 and M-104. A graphic with dimensions for U1 T32 pipe is provided as Figure 34.

Figure 34 - T32 Unit 1 16" Service Water Supply to Diesel Generator Heat Exchangers As seen on M-106 the Diesel Generator Floor is at 5676 and the pipe below it is at 5636 resulting in a vertical rise to the floor penetration at J31 and J9. The horizontal run is 4 feet below the Diesel Generator Building floor. There is also a vertical rise at G31 and G9 from 55310 to 5636 or 9.67 feet. The line runs north under the Turbine Building floor at 55310 which is 62 below the 560 elevation floor. The length from J to G is 42. M-106 shows the floor penetrations at J31 and J9.

M-103 and M-106 Section A-A show the top view and the side view of the pipe existing the Turbine Building these sections are provide in Figure 38.

As seen in Figure 38 and Figure 37, the horizontal sections traversing from the Turbine Building to the Crip House at the 586 will be cut and removed leaving the buried vertical sections.

Figure 38 - 20 Inch Condensate to Alternate Feedwater Pumps Penetration Exiting Turbine Building Drawing B-559 shows the Oil Room wall exterior is 11 feet from row B which is 14 feet from Row A. As seen in Figure 38, the pipe exits the building at a 45 degree angle this means the pipe exiting the building foundation then bends 90 degrees upward at two feet from Row A. This results in a 69 base and 12 height resulting in a hypotenuse length of 13.77 feet from the 20 to 18 reducer within the wall to the vertical bend upward to the 586 elevation. The vertical pipe length from the 5569 to 586 or 29.25 feet. The buried pipe section of the Condensate from the exit of the Oil Room foundation to the cut line is shown in Table 46. The 4 Condensate line parallels the 20 line but exits the foundation 1.5 feet higher at 5583 or 19 below the 560 floor. Resulting in a vertical length of 279. As seen in Figure 39, the embedded portion in the TB foundation is shown on M-103. Shortly after entering the Turbine Building foundation they run through the slab and emerge on the west side of the 560 floor at G22. M-103 shows 180 feet from column A to G. The 18 T103 penetration is 56 below G making it 1746 long. Other dimension show the distance from the centerline of the pipe forming a 45 degree triangle at 129 long.

TSD 14-016 Revision 0 This results in a length of 1619 from A to the 45 degree bend for the 18 pipe. The 4 inch pipe is offset by 2 feet from the 18 pipe resulting in a length of 1599 from A to the 45 degree bend. The 45 degree bend section of each pipe is the hypotenuse of a 45 degree triangle with 129 sides or 18.03 feet. The 4 inch diameter pipe vertical section to the floor is 19 and the 18 pipe vertical section is 33. The lengths, diameters, surface areas and volumes are summarized in Table 46. As seen in Figure 39, the 4 Condensate line T105 runs beneath the floor at the 5583 elevation making it 19 below the floor. The 18 Condensate line T103 runs under the floor at the 5569 elevation making the top of the pipe at the 5576 elevation or 26 below the floor. T106 runs under the floor at the 5569 level, 33 below the 560 floor.

Aerated Drain piping from equipment drains, floor drains, and sump piping remains in the end state Turbine Building slab below the 560 elevation. The estimated piping lengths and diameters were inventoried in the preparation of FSS Plan 06105B Turbine Building Embedded Piping Drawings used in developing the FSS Plan are as follows: (6)

B-452 Turbine Building Plumbing Basement Floor Plan Unit 1 B-454 Turbine Building Plumbing Diagram Basement Floor Plan Unit 1 B-471 Turbine Building Plumbing Basement Floor Plan Unit 2 B-473 Turbine Building Plumbing Diagram Basement Floor Plan Unit 2 M-103 Zion Station Unit 1Turbine Building Piping, Misc. Piping in Structure Embedded system piping surveyed by this survey plan included the floor drain and equipment drain systems below the 560 elevation of the Turbine Building. These systems consist of inputs and connecting piping that terminates at one of four drain sumps (Unit 1 Equipment Sump, Unit 2 Equipment Sump, Turbine Building Floor Sump and the Fire Sump) beneath the 560 el. floor.

The floor drain system on the 560 el. consists of 26 floor drain inputs, the floor drains from the Clean and Dirty Oil Storage Tank Rooms, the continuation of the Emergency Diesel Generator Fuel Oil Storage Tank Room floor drains from the 567 el., and the continuation of the floor drain systems from the Turbine Building 592, 617 and 642 elevations from where they enter the floor of the 560 el. to their connection to Page 56 of 123

TSD 14-016 Revision 0 the embedded drain piping (approximately 1,250 linear feet of varying diameter drain pipe which connects all floor drain inputs) and terminating at either the Turbine Building Sump or the Fire Sump.

Also included is the Unit 1 equipment drain system consisting of input associated with components located on the 560 and 562 elevations and the common area between Units 1 and 2, the continuation of the Unit 1equipment drains from the 642, 617, and 592 from where they enter the floor of the 560 el. to their connection to the embedded equipment drain piping (approximately 300 linear feet of varying diameter equipment drain system piping) terminating at the Unit 1 Equipment Sump.

Also included is the Unit 2 equipment drain system consisting of input associated with components located on the 560 562 elevations, the continuation of the equipment drains from the 642, 617 and 592 elevations of Unit 2 from where they enter the floor of the 560 el. to their connection to the embedded equipment drain piping (approximately 200 linear feet of varying diameter equipment drain system piping) terminating at the Unit 2 Equipment Sump.

The polishing filter system drains consist of 2 inputs located in the common area, connected to 2, separate 10 diameter pipe systems that terminate at inputs to the fire sump, total length of 10 diameter pipe is approximately 180 linear feet.

The varying pipe diameters are apparently related to progression in the number of inputs to the different systems (more inputs, increased pipe diameter). The surveys were performed at the discharge end of the pipes in the sumps. During performance of the survey, pipes were found to be larger in diameter than what was identified in the survey plan based on available drawings (6vs 4 and 8vs 6).

The estimated length of pipe was based on the drop from the 560 el. to the lateral pipe run (approximately

4) plus the estimated lateral run of the pipe base on turbine building column line dimensions, as the drawings are difficult to read. In some cases, the total length of a given diameter of pipe could not be determined consequently an exaggerated total length was used in order to build conservatism into the survey plan.

The estimated pipe section diameters and lengths are summarized in Table 47.

Circulating Water Intake Piping The Circulating Water Supply to the Condensers consist of embedded pipe through the Crib House Wall, buried pipe from the Crib House to the Turbine Building Foundation and Embedded pipe from the Turbine Building foundation as seen in Attachment C. The section below the condensers is shown in Figure 41.

Assuming the 9 foot diameter supply pipes (T109, T110, T120, T121 in Unit 1 and T123a, T123, T133, T134 in Unit 2) are cut above the water table at the 580 elevation and grouted. The floor elevation is 572. The average length to the 12 foot diameter line below 572 to the connection to the 12 foot diameter pipe is conservatively estimated at 26 since some of the surface area extends below the top of the pipes at the 570 elevation. Thus, their total embedded length is 2.5 feet. Notation on M-100 which is retained in Attachment C shows a 1 inch pipe wall thickness for the 9 diameter piping.

The 36 diameter manways to the 12 Diameter Circulating Water Supply line (T83, T85, T87, T88) are 9 feet long if they are cut flush with the concrete as seen in in Figure 41. Figure 41 also shows that each of the four (T111, T122, T143, T124) 12 foot diameter pipes below the condenser. These pipes have a 1.25 inch wall thickness as seen in M-100.

Circulating Water Discharge Piping Circulating Water Discharge piping in the Turbine Building consists of a 48 inch (T75, T76) and 36 inch stand pipe (T84, T86), a 36 inch manway entrances to the Discharge Tunnel (T135, T136) and two 12 foot interior diameter discharge pipes from the condenser for each Unit (T77, T78, T80, T81). The top view is provided in drawing M-15, the side view is from drawing B-100 as shown in Figure 44 and in Figure 45.

Penetrations T75and T77 are the Unit 2 Circulating Water Discharge Stand Pipe located at F9 and F31 in the Turbine Building as shown in Attachments A, B, C and Figure 44. A side view is provided in Figure 45 from B-100. It can be seen that the pipe runs vertically through the Turbine Building slab from the 592 to 22 above the 5616: elevation at the middle of the 45 degree bend into the discharge tunnel. The vertical drop will be from the 588 elevation to the 5638 elevation. This makes the vertical section 24 4 long as seen in Figure 45. The base of the triangle formed by the slanted section from the Discharge Tunnel wall to the center of the pipe is 108. The vertical drop is 136 this results in a hypotenuse of 14.27 feet forming an overall length of 42.6 feet.
