PURPOSE The prim ary purpose of this TSD is to provide bounding and conservative estim ates of the concrete surface areas, volumes and void spaces in th e La Crosse Building basements that will rem ain as part of the end state during License Term ination. The La Crosse License Termination Plan (LTP) (1) states that structures will be removed to 3 feet below grade. These estimates are for the basements of the structures that are greater than 3 feet below grade.

2.

DISCUSSION OR BACKGROUND 2.1.

End State Structures The La Crosse LTP (1) states that structures will be removed to 3 feet below grade. Grade level is the 639 foot elevation at the site. Therefore basement structures below the 636 foot elevatio n will remain as part of the end state and will require characterization and survey in order to meet the 10 CFR 20 Subpart E (2) release criteria. As seen in Figure 1, the im pacted end state structures below grade consist of the Gas Tank Vault and the four Piping and Ventilation T unnels, W aste Disposal Build ing, Chi mney Slab, Containment, Reactor Building and Generator Building. There is also a small sump and dirty oil room pit at Columns C1 and G5 in the Turbine Building that are below the 636 foot el evation. The base of the Chimney Foundation is at 635 3 as shown in s ection AA of La Crosse Drawing 41-503435, and the top is at 639 3 it is assumed that the remaining 9 inches of slab below the 636 foot elevation will be part of the end state, although it is unlikely to surviv e the demolition process. This may also be the case for the Section of the W aste Disposal Build ing at the 635 foot elevation and the Turbine Building Sump at the 634 foot elevation and P it at the 633 foot elevation, but their surface areas, volum es and void spaces are calculated as well. All other structures, including the interior walls, tunnel rooves that are below 636 foot elevation have been include in the concrete su rface area and volume estimates. The surface areas of the tops of the walls at the 636 elevation have not been included in the surface area calculations. In addition, only the exposed interior surface area s are calculated. The ex terior surface areas are surrounded b y soil, including the tops of the walls are not likely to be contaminated. Therefore only interior surface areas are calculated in this document. In order to aid in backfilling structures such as tunnels it may be expedient to remove structures such as tunnel ro ofs to lower elevations since the wa ter table at La Crosse is 20 feet below grade at the 619 foot elevation. Seasonal floodi ng occasionally raises the water table to the 629 elevation.

2.2.

Calculations Performed and Intended Use This docum ent es timates the in terior surf ace a reas of th e end state structures as well as th e concre te volumes of the walls, floors and ceilings. In order to be bounding and conserva tive the concrete volum e of piers and other deep foundations ar e not included. This would further dilute the remaining source term and resulting concentrations for alternate scen arios evaluated. The su rface areas will be used es timate source terms using characterization and Source Term Survey (STS) data. This document also calculates the end state void spaces of the basem ents and the void space below the 619 foot elevation water table if present. The concrete volumes will be used to evaluate alternate scenarios and the void space information will be u sed to eva luate the po tential for end state structures to support a we ll in the r esident farmer scenario and if so, the pot ential radionuclide of concern concentra tions in the water. There is a sm all sump in the Gas Tank Vault and a sm all portion of the Containm ent Liner that are below the 619 elevation, therefore it is unlikely that there could be a viable well in the end state structures.

CALCULATIONS 3.1.

Waste Gas Tank Vault The Waste Gas Tank Vault is 29 6 wide by 31 6 long as seen in Figure 1. It has a center dividing wall, a sump and 3 supports in each r oom for the tanks. The top of the roof slab is 3 feet below grade at the 636 foot elevation as seen in Figure 2. Although it is likely the roof will be removed to facilitate tank removal and backfill, its surface ar eas and concrete volum es will be estimated to ensure conservatism.

The calculated surface areas, concrete volumes and void spaces with and without the Gas Tank Vault roof are provided in Table 1 at the end of this section.

Figure 2 - Waste Gas Tank Vault Side View from 29' 6" Side from Drawing 41-503435

RS-TD-313196-002 Revision 0 Page 10 of 60 Figure 3 - Excerpt of Waste Gas Tank Vault Roof Slab Plan Showing Tunnel and Hatch Details from 41-503435 The roof is 1 foot thick, as seen in Figure 2, and ha s two hatches, as seen in Figure 3. One roof hatch has a 3 by 26 or 7.5 square foot opening. The other roof hatch over the piping and ventilation tunnel entrance is 4 by 36 or 14 square feet. The top of the roof is 29.5 by 31.5 or 907.75 square feet when the 21.5 square foot hatch openings are s ubtracted from it. Since the roof is 1 foot thick the concrete volum e is 907.75 cubic feet.

There is a 1 6 thick center wall dividing the vau lt into two com partments. As seen in Figur e 4, this results in two interior ceiling sect ions (e.g., underside of roof) that ar e 13 feet by 29.5 feet or 819 square feet which is 745.5 square feet when the surface areas of the hatch openings are subtracted from the total.

The floor slab is also 29.5 by 31.5 feet and 1 foot thick or 929.25 cubic feet. As seen in Figure 2 there is a 1 2 thick section labeled Secti on B whose volum e can be calculate d as 1.5 feet (e.g., 18) by 12 by 31.5 feet plus 12 by 12 by 31.5 feet or 98 cubic feet. The floor surface area is 13 by 29.5 for each of the two compartments or 767 square feet for both compartments.

The outer walls are from the 635 foot elevation to the 621 foot elevation or 14 feet high since the volumes of the roof and floor slabs have already been calcu lated. The outer length of the walls is 29.5 feet and 31.5 feet minus the 1 foot thick walls of the 31.5 foot width at each end which re sults in 29.5 feet for all four walls. This multiplied by the 14 foot height and 1 foot thickness is 1652 cubic feet of concrete.

RS-TD-313196-002 Revision 0 Page 11 of 60 Figure 4 - Waste Gas Tank Vault Floor Slab Top View The interior surface area of the outer walls is, two walls 14 feet high by 29.5 feet long or 826 square feet and four walls 13 feet wide by 14 feet high or 728 square feet.

RS-TD-313196-002 Revision 0 Page 12 of 60 void space of 13 by 29.5 by 14 for each of the two chambers or 10,738 cubic feet total. Th e seasonal flooding void space below the 629 foot elevation is 6,170.60 cubic feet.

The center dividing wall is 14 feet high by 29.5 feet l ong and 1.5 feet thick for a concrete volum e of 619.5 cubic feet. The surface area o f the two interior wa lls is 29.5 feet by 14 feet for both walls or 826 square feet. If the roof is removed the exposed surface area at the top of the center wall is 1.5 feet by 29.5 feet or 44.25 square feet.

As seen in Figure 4 there are 6 ta nk support that are 8.75 feet long. The side view of a support shown in Figure 5 shows they are 6 inches wi de and 1 foot high. T he top surface area is already in cluded in the overall floor surface area. There are 12 ends that are 0.5 feet by 1 foot or 6 square feet. The total volum e is 1 ft by 0.5 ft by 8.75 feet by 6 supports or 26.25 cubic feet. There are 12 1 foot by 8.75 foot sides equaling a total surface area of 105 square feet.

Figure 5 - Tank Support Side View from Drawing 41-503435 The floor elevation is 621foot. As seen in Figure 4 there is a 3 3 by 3 3 wide, by 3 foot deep, sum p in the floor slab with a bottom elevation of 618 foot. Assuming the 7/8 inch thick liner shown in Figure 4 is removed makes each side 33 + 14/8 or 3.40 feet wide. The surface area of the four walls of the sump is 3.4 feet by 3 feet by 4 walls or 40.75 square feet. As s een in Figure 2 the outside width of the sump is 5 6 making the walls 5.5 - 3.4 divided by 2 or 1.052 f eet thick. The wall heights f or concrete volume calculations 621 - 617are 4 feet minus the 1 foot thickne ss of the floor slab or 4 feet. All of the walls are 1.052 foot thick. Two walls have an outside length of 5.5 feet resulting in a concrete volume of 23.15 cubic feet per wall or 46.29 cubic feet for both. Two walls have a 3.40 foot width resulting in 14.29 cubic feet of concrete per wall or 28.58 ft 3 for both. The surface area and con crete volume of the 1 foot thick bottom of the sump is already inc luded in the f loor slab surface area and volum e. The void space of the sump is 3.4 by 3.4 by 3 feet or 34.6 cubic feet. One thir d of this volume or 11.53 cubic feet is below the water table at the 619 foot elevation. The calculated surface areas, concrete volumes and void spaces with and without the Gas Tank Vault roof are provided in Table 1.

Waste Disposal Building As seen in Figure 1 portions of the waste disposal building are below the 636 foot elevation. The ground floor plan of Figure 6 from drawing 41-503474 (F ile 022587) shows the layout of the 630 foot elevation.

Another excerpt from the drawing is provided as Figure 7. A side view showing the 630 foot floor slab to be 1 foot thick is provided as Figure 8. Because the in terior and exterior wa ll thicknesse s vary the interior floor surface areas have been divide into 3 sections (A, B, C).

The overall floor slab concrete volume is approximately 14 6 by 31 by 1 or 449.5 cubic feet. S ection A1 floor width is 21.5 feet (e.g. 84 plus 8 plus 7 plus 2.5 plus 3 ) and the length is 9 6 (e.g., 13 3 m inus 6 minus 9 minus 2 6), as seen in Figure 6, equaling a surface area of 204.25 square feet. The wall height is

RS-TD-313196-002 Revision 0 Page 16 of 60 from the 636 to 630 o r six feet. T he section A1 204.25 square foot s urface area multiplied b y a 6 foot wall height equals 1,225.50 cubic f eet. Section A2 is 16 feet (e.g., 84 pl us 8 plus 7) by 2 6 or 40 square feet. The 40 square foot ar ea multiplied by the 6 foot wall hei ght equals 240 cubic feet. T he total Section A void space volume is 1465.50 cubic feet.

As seen in Figure 6 Section B is 7 0 wide by 96 (14 6 m inus 9 m inus 3 minus 13) long for a floor surface area of 63.17 square feet. When the Section B surface a rea is multiplied by the 6 foot wall height the calculated void space is 379 cubic feet. Section C is 12 6 wi de (7 plus 2.5 plus 3) and 3 6 long resulting for a 40.42 square foot surface area, which equals a 242.5 cubic foot void space.

As seen in Figure 7, the top wall inne r length of Section A1 is 16 pl us 2.5 plus 3 feet or 21.5 feet equaling a surface area of 129 square feet with a 6 foot wall height. Th e wall is 1.5 feet thick equaling a concrete volume of 193.5 cubic feet. The Section A left wall outer lengt h is 133 + 9 +6 or 14 6 which equals a concrete volum e of 130.5 cubic feet. The inner length of the secti on A left wall is 13 3 minus 9 and 6 or 12 feet which equals a surface ar ea of 72 square feet. As seen in Figure 7, the inner length of the Section A1 bottom wall is 16 feet (e.g., 84 + 8 + 7 0) which equals a surface area of 96 square feet and a volu me of 96 cubic feet sin ce the wall is one f oot thick. Sect ion A1 has a right hand wall that is 2.5 feet long by 6 feet high or 15 square feet. This abutm ent also forms a bottom wall of Section A1 that has a 15 square foot surface area. The outer length of the abutm ent is 3.5 feet equaling a concrete volume of 2.5 by 3.5 by 6 or 52 cubic feet.

As seen in Figure 6 and Figure 7 th ere is a 9.5 foot by 2.5 foot inte rior cinder block wall between Sections A1 and B. There are two 9.5 by 6 foot surfaces equaling 114 square feet with a 2.5 by 6 foot end equaling 15 square feet. The wa ll outer length to the back of the top wall is 1.5 feet plus 9.5 feet or 11 feet, equaling a concrete volume of 2.5 by 11 by 6 or 165 cubic feet.

RS-TD-313196-002 Revision 0 Page 19 of 60 As seen in Figure 9, the tangent line at which the si des are no longer straight and the liner becomes an ellipsoidal head is at 627 6 elevation. Above this elevation the surface areas and volumes are calculated based upon a cylinder.

The surface area of a cylinder is the circumference of the circle multiplied by the height.

Equation 1-Surface Area Walls of a Cylinder 21602.21 Where; R = the radius of the cylinder (e.g., 30 feet) h = height of the walls 8.5 feet The height of the wall is 636 -627.5 or 8.5 feet. The wall surface area of the liner is 1,602.21 square feet.

The volume of a cylinder is shown in Equation 2.

Equation 2 - Volume of a Cylinder This equals 24,033.18 cubic feet.

The liner below the tangent line is an elliptical head with parameters for calculating surface area and volume as shown in Figure 10.

Figure 10 - Variables for Calculating Surface Area of and Elliptical Head

RS-TD-313196-002 Revision 0 Page 20 of 60 The surface area of an elliptical h ead is c alculated using the sam e equation a s is used f or the wetted surface area of a vertical elliptical head tank, Equation 3. (3)

= Eccentricity of Elliptical Heads (e.g., 0.864) 1 4

z = the inside dish depth (e.g., 15.09 feet)

The bottom of the liner is at 612 4 29/32 inches. This is 15.09 feet below the ta ngent line resulting in an elliptical head surface area of 3,904.15 s quare feet for a total end state liner in terior su rface area of 5,506.36 square feet.

The void space volum e is calculated using the v olume of an ellipsoidal tank bottom as shown in Figure

11.

3 Where D = 60 feet h = 15.09 feet a = 15.09 feet This equals 28,446.14 cubic feet for a total liner void sp ace below 636 foot of 52,47 9.32 cubic feet. If Equation 4 is used with h = 23.59 and a = 15.09 feet Equation 4 results in the same volume of 52,479.32 cubic feet.

The seasonal flood level of 629 feet is 1.50 feet above the tangent line equaling and area of 287.24 square feet using Equation 1 and 4,241.15 cubic feet using Equation 2.

Since the bottom the liner is at the 6 12 foot elevation some of the void space volum e is below the water table. The height of the portion below the water tabl e is 6.59 feet. As seen in Figure 9, the radius was interpolated to be 25 fee t at the 619 foot elev ation. Using Equation 3, a surface area of 2,646.77 square feet. The volume below the water table, using equation Equation 4, is 4,829.46 cubic feet.

The calculated surface areas and volumes with all interior concrete removed are summarized in Table 6.

.46 The external concrete volumes outside the liner were calculated by breaking the concrete into sections as shown in Figure 9.

RS-TD-313196-002 Revision 0 Page 22 of 60 The concrete volume outside the line r is calculated in two w ays. The concrete volume above the tangent line at 627 6 is calcu lated as the difference in vol ume between an inner diam eter and outer diam eter cylinders using Equatio n 5. Because the ex terior concrete below the tangent li ne is form ed around the bowl shaped liner, the concrete volume is initially calculated as a monolith, as if the liner was not present and considering it to be one solid m ass across the entire radius. Then, the liner v oid space volum e of 28,446.14 cubic feet is subtracted from it to calculate the volume of concrete outs side of the liner.

As seen in Figure 9 and Figure 12, the concrete surrounding the liner above the tangent line is 9 inches or 0.75 feet thick.

Equation 5 - Volume of a Cylinder Wall Where ro = Outer radius of 30.75 feet ri = Inner radius of 30 feet h = height of 636 - 627.5 or 8.5 feet.

This equals 1,216.68 cubic feet.

Th ere is no void space in the initial calculati on of the concrete volume below the ta ngent line. The 28,446.14 cubic feet of the void space below t he tangent line in Table 6 will be subtracted from the cal culated volume of the monolith to estimate the volume of the concrete outside t he liner below the tan gent line. The monolith is broken into sections k through p as shown in Figure 14, to si mplify the calculation of each s ections volume. The summation of each sections m onolith volume minus the inte rior void spac e below the tangent line will app roximate the co ncrete volu me outside the line r be low the tangent line.

The volum e of a so lid concrete disk 1.5 feet thick with a 30.75 foot radius is calculated using Equation 2, and results in a calculated volume of 4455.86 cubic feet.

Figure 14 - Reactor Containment Monolith Sections Section l has a height of 1.5 feet as seen in Fi gure 12, Figure 13, and Fi gure 14 with a width of 1.5 feet making the outer radius 32.25 feet and the inner radius 30.75 feet. Sin ce it is triangular in shape the volume is half the volume calculated using Equation 5 or 222.66 cubic feet.

RS-TD-313196-002 Revision 0 Page 25 of 60 Section m is 4.5 feet h igh with a rad ius of 32.25 feet making the monolith volume 14,703.54 cubic feet using Equation 2. Section n is 5.54 feet high with a radius of 33.25 feet as seen in Figure 9 and Figure 13.

This results in a volume of 19,247.47 cubic feet. Section o is a triangular shaped outer ring like section l.

The outer triangular ring of o has an outer radius (r o) of 333 minus 7 2 or 26.08 feet. The inner radius (ri) is 26.08 feet minus 7 3.5 or 18.79 feet and the height of 615 11.5 minus 612 4 29/32 making o 3.55 feet thick. S ince it is triangular in shape the volum e is half the volum e calculated using Equation 5 of 1,824.38.

The center cylinder section p surrounde d by o is 3.55 feet thick with a radius of 18.79 feet resulting in a volume of 3,937.72 cubic feet using Equation 2. The volume of Section q is calculated the same way as o.

The outer radius (r o) is 18.79 feet. A s seen in Figure 9, the inner radius is 7 6. The height (h) is 612 4 29/32 m inus 609 6 or 2.91 feet. Half of the Equati on 5 volum e results in 1,356.49 cubic feet for q.

Section r is a 2.91 foot thick disk with a7.5 foot radius resulting in a volum e of 514.04 cubic feet. The total volume of section k through r results in a m onolith volume of 46,262.16 cubic feet. When the Table 6 liner volume void space of 28,446.14 cubic feet below the tangent line is subtracted from that volume, it equals 17,816.02 cubic feet of exte rior concrete below the tangent line. When the 2,433.36 cubic foot concrete volume above the tangent line in Table 7 is added to it the to tal exterior concrete volum e is 20,249.38 cubic feet as seen in Table 8.

Piping and Ventilation Tunnels As seen in Figure 1, there are several piping and ventil ation tunnels in the end state that connect the Gas Decay Tank Vault, Chimney, Containm ent, and React or Building. A long tunnel runs from the Reacto r Building under the Con tainment access area th rough the chimney tunnel area to the Gas Decay Tan k Vault. Two other short tunnels conn ect to the m ain tunnel. A short tu nnel to the Chim ney and a short tunnel from the Containment pipe penetrations to the Chimney area of the tunnel.

The width, elevations and geometries vary over the length of the main tunnel, so it is broken into sections to calculate the surface areas, concrete volumes, and void spaces. Sections A thro ugh C are from the Waste Gas Decay Tank Vault through the Chimney common area as shown in Figure 15 and Figure 16.

Section B, has 145 by 146 rectangle m inus a 67 1/2 by 4.25 feet triangle section. The 4.25 feet is calculated using 14.42 feet minus 74 plus an estimated floor thickness of 1 foot as shown in Figure 17.

The surface area is 14.42 by 14.5 feet minus one half 6.63 by 4.25 feet or 194.96 square feet. With a wall height of 636 foot minus 633.5 feet or 2.5 feet this equals a void space of 487.41 cubic feet.

The Section B floor slab volum e is the length and wi dth plus 2 feet o n each d imension for th e portion under the w alls (e.g., 16.42 feet by and 16.5 by 1 foot thick) or 270.88 cubic feet, m inus the triangular section which is one half of 5.25 by 7.63 by 1 foot thick or 20.16 cubic feet. This equals 250.86 cubic feet for the Section B floor. There is a portion of the wall where Section A and B meet that is not accounted

The top wall adjacent to the Waste Disposal Building is 2.5 feet high by 14.42 feet long o r 36.04 square feet. As seen in Figure 7, a portion of the top walls volume corresponds to Sections B and C of the Waste Disposal Building. As seen in Figure 6 and Figure 7, the OD Section B & C Wall lengths are (1 6 plus 9 6 plus 3 6 plus 1 f t) or 15 6. As s een in Figure 16, from Drawing 41-503440 File # 022555, the Section B tunnel is 16 plus 7 1 from the oute r surface of the W aste Disposal Building Section B outside edge or 23.08 feet. So the unaccounted for volum e of the wall is 2.5 feet high by 7.58 ft by 1 foot thick or 18.96 cubic feet.

The left wall triangle hypotenuse is the square root of 4.25 feet squared plus 6.63 feet squared which is 7.87 feet. The surface area is 2.5 by 7.87 or 19.68 square feet and a volum e of 19.68 cubic feet. The bottom wall length is 14.42 feet minus 4.25 feet and minus the 58 opening of the tunnel to the chimney or 4.5 feet resulting in a surface area of 11.25 square feet and a concrete volume of 11.25 cubic feet. The right wall is 10.5 feet long resulting in a surface area of 26.25 feet and a volume of 26.25 cubic feet.

The surface area is 23 by 24 feet m inus one half of 7.25 feet by 7.67 feet or 524.21 s quare feet. With a 7 foot wall height this equals a void space of 3,669.46 cubic feet.

Figure 32 - Section I Side View from Section AA of Drawing B-28 File Name 022888 As seen in Figure 32, the interior floor slab is 3 3 thick resul ting in a volum e of 1,703.68 cubic feet.

The portion under the walls will be calculated using a 1 foot wall height for the concrete volume.

The top wall of Section I is 24 feet minus 19 7 or 4 5. T his is 30.92 square feet with a 7 foot interior wall height and 45.27 cubic feet of concrete with a 10.25 foot wall height to the base of the floor slab.

The left wall length is 15 9 pl us 5 or 16 2 or 16.17 feet. The su rface area of th e wall is 16.17 by 7 feet or 113.17 square feet. The volume is 16.17 by 10.25 by 1 feet or 165.71 cubic feet. The hypotenuse of the triangle wall length is the square root of 73 squared plus 7 8 squared or 10.55 feet. The surface area is 73.86 square feet. The concrete volum e is 10.55 by 10.25 by 1 feet or 108.16 cubic feet. The bottom wall is 16 4 plus 5 inches or 16 9 whic h is 16.75 feet.

W ith a 7 foot interior wall height th is equals 42.15 square feet. The top side of the angled wall approxim ately 8 feet lon g resulting in a surf ace area of 56 s quare feet. At 2 feet long this equals a volum e of 112 cubic feet which is subtracted from the void space. The bottom surface intersection with the floor is 16 squa re feet which results in a 117.25 square foot surface area per side or 234.50 square feet for both sides. T he concrete volume is 234.50 cubic feet which is subtracted from the void space.

There is also a 3 foot by 1 foot column in Section I as seen in Figure 30. This results in 42 square feet for the 3 foot sides and 14 square feet for the 1 foot sides and adds 21 cubic feet of concrete volume.

Figure 33 - Lower Left Wall Section J Excerpted from Drawing 4`1-503443 File 022588 The width is 2 3 plus 22 3 plus 6 6 or 31 feet. As seen in Figure 30, there are sections of the containment (J1 and J2) whose areas are w ithin Section J. Interpolated values were used to estimate the

RS-TD-313196-002 Revision 0 Page 46 of 60 surface areas of J1 and J2 in som e instances since no drawings were found with Section J and K details other than M-6 and B-41 which were limited in details.

Drawing M-6 has angles to som e C ontainment penetrations that can be used to close ly es timate the degrees of the angle representing J1 and J2. These angles were inverted in order to estimate the angles of J1 and J2 where they intercept the outer surface of the containment.

Figure 34 - Excerpt from M-6 Showing Angles to Penetrations As seen in Figure 34, the angle of J1 is approxim ately 31 degrees and J2 is 19 degrees and 31 arcm inutes or 19.35 degrees where one arcminute equals 1/60th of a degree.

The area of a portion of circle of n degrees can be calculated using Equation 6.

Equation 6 - Area for Portion of a Circle

360 When the area of the triangle above it is subtracted from the area calculated in Equation 6m the remaining area. Containment has a 30 foot inner radius. A s shown in Figure 12, the concre te above the 629 foot elevation is 9 or 0.75 feet th ick making the radius to the extern al surface 30.75 feet. The area of the portion of the circle represented by J1 is calculated using Equation 6.

36 360 30.75297.06 Drawing B-23 (File 022888) shows a 21 6 length from Column D to the center of the containm ent. As seen in Figure 30 the left boundary of Section J is 1 6 closer to the center line of the containment than Column D is. This m akes the distance from the left had boundary of J to the Containm ent center line 20

RS-TD-313196-002 Revision 0 Page 47 of 60 feet. The left hand side of the Containm ent wall inte rcepts the upper boundary of Section J at 2 3 in from the 20 width from the boundary of J to the containm ent center, making the radius of Section J1 at 17 9.A scale with 1 foot increm ents was created from the drawing to es timate the distance from the outer surface of the containm ent to the intercep t with the upper border of Secti on J as seen in Figure 34 this is estimated at 6.2 feet meaning the height of triangles are 30.75 minus 6.2 or 24.55 feet. The area of J1 to be subtracted from the rectangular total is therefore:

36 360 30.75 0.5 24.55 17.75297.06 217.88 79.18 Similarly the area of J2 is the 19.35 degree (e.g., 15 +4 +21/60) area of the circle minus the triangle. The triangle base at the point where it intercepts the top boundary of J2 was interpolated from a scale of 1 foot increments. It is 1.5 feet smaller than the 11 1 span of J2 or 9 7 which is 9.58 feet.

19.35 360 30.75 0.5 24.55 9.58117.64 118.83 42.03 There is also a sm all 1.5 foot by 3 f oot triangle in the upper right corner of J2 that is outs ide the 19.35 degree line. This 2.25 square foot area also needs to be part of J2 m aking J2s surface area 44.28 square feet.

The floor surface area is 31 by 26.5 feet or 821.5 square feet minus the areas of J1 and J2 (e.g., 79.18 plus 44.28 square feet) resulting in a floor area of 698.04 square feet. With a 7 foot wa ll height, this creates a void space of 4,886.29 cubic feet. Sec tion T-T of drawing B-11 (file 0 22875) shows a side view of the floor slab at Column 10 from Column A to F. An excerpt is provided in Figure 35. It shows that the floor slab of J is thinner than that of I at 1 foot thick. The interior floor slab volume is 698.04 cubic feet.

Figure 35 - Side View of Columns A through F at Column 10 from Drawing B-11 File Name 022875 The portion of the floor slab under the walls will be calculated using an 8 foot wall height for the concrete volume. A portion of the 2 3 porti on of the top wall is pr esent in the upper left corner of J before it intersects the containment wall. Th e interior surface area is 2.25 feet by 7 feet or 1 5.75 feet. The wall height for the volume calculation is 8 feet resulting in a concrete volume if 18 cubic feet. The surface area of the containment wall is calculated using Equation 7. Section J1 and J 2 span 53.35 degrees resulting in 207.94 square feet. The volume of the containment exterior concrete was calculated in Section 3.3

Since 1 foot of the concrete volume was already included in the volume of the wall in Se ction I, the Se ction J volume is 2 6 by 8 by 1 for the concrete volume or 20 cubic feet. The bottom wall length is 31 feet m inus the 10 9 of section K or 20.25 feet with surface area of 141.75 square feet and a concrete volume of 20.25 by 8 by 1 foot or162 cubic feet. The right wall is 26.5 feet long m inus the 4 feet in S ection J2 or 22.5 feet long. The surface area is 22.5 by 7 feet or 157. 5 square feet. The vo lume is 22.5 by 8 by 1 feet o r 180 cubic feet.

As seen in Figure 30, there are 2 foot thick interior walls in J. The dimensions for these walls are obtained from drawing 41-503468. The extension of the horizontal wall from Section I is 6 feet long. This equals a surface area of 42 square feet p er side. The surface area of the end is 2 by 7 feet o r 14 square feet. Th e concrete volume is 6 by 7 by 2 or 84 cubic feet of concrete which is subtracted from the void space total. There is also a 2 by 6 surface area of 12 square feet which is subtracted from the total surface area of the floor.

RS-TD-313196-002 Revision 0 Page 49 of 60 The interior wall show in Figure 36 has had the calculated dimensions added to Figure 30. The top face of the wall has a su rface area of 16 b y 7 or 10.5 feet. At 2 feet thick this 21 cubic feet of concrete that is subtracted from the void space. The slanted top face is the hypotenuse with a length of the square root of 2.5 feet squ are plu s 2.5 feet squared or 3.54 feet equ aling a surface area of 24.7 5 square feet and a concrete volume of 49.5 cubic feet. The straight portion is 5 feet l ong resulting in a su rface area of 35 square feet and a concrete volume of 70 cubic feet. The top of the horizontal face is 66 wide resulting in a surface area of 45.5 square feet and a concrete volume of 91 cubic feet. The top surface of the angled portion is the square root of 3.25 feet squared plus 3.25 feet squared or 4.6 feet resulting in a 32.17 square foot wall face and a concrete volume of 64.35 cubic feet. The total length covering the floor is 26.13 feet or 182.92 square feet that is subtracted from the floor surface area.

Looking at the upper left hand face and the lo wer side of the wall su rface areas, the 2 foot thick end results in 14 square feet. The bottom lip is estimated at 3 inches resulting in 1.75 square feet of surface area to the floor. The lower face of the angles side is estimated to have a height and base of 1 3 making the length of the side the square root of 1.25 f eet squared plus 1.25 feet squared or 1.77 feet wide resulting in a wall surface area of 12.37 square feet. The vertical face is 5 minus 1.25 plus 2 plus 4 or 9.75 feet resulting in a 68.25 square foot surface area. Six feet of the vertical wall was not included in the concrete volume calculation or the surface area covering the floor. The 6 by 2 7 volume is 84 cubic feet and the surface area of the floor covered is 12 square feet. The bottom end is 2 feet by 7 feet or 14 square feet. The inside vertical face is 4 feet, resulting in 28 square feet. The underside of the horizontal face has an estimated width of 5.5 feet resu lting in a surface area of 38.5 square feet. The base of the triangle for the slanted side is 9 9 m inus 5 6 and 2 feet or 2 3. The hypotenuse is 3.18 feet resulting in a 22.27 square foot surface area. Th e bottom inner face is 83 m inus 2 feet and 2 3 or 4 feet resulting in 28 square feet.

Section J also has a 1 foot by 1 foot interior colum n as seen in Figure 3 0, resulting in an additional 28 square feet of wall surface area and 7 cubic feet of concrete.

RS-TD-313196-002 Revision 0 Page 51 of 60 As shown Figure 37, Section K is 10.75 foot by 12 foot or 129 square feet interior dimension.

Figure 37 - Section K Top View from Drawing B-8 File Name 022940 As seen in Figure 38, the floor slab and sum p floor slab is 1 foot thick m aking the floor concrete volume 129 cubic feet with a 7 foot depth eq ualing a void space of 903 cubic feet. The left and right sid e walls are 7 feet by 12 feet or 84 square feet per wall with a 168 square foot surface area for both walls. With a 8 foot depth for the concrete volume this equals 192 cubic feet of concrete. The back wall by the stairs and sump is 1 plus 3 plus 2 plus 5.75 plus 1 or 12.75 feet equaling 89.25 square feet for the surface area.

The 2 foot thick shield wall betwee n the sump and the stairs obstructs 14 square feet of the surf ace area, making it 75.25 square feet. At 8 feet high the back wall concrete vol ume is 102 cubic feet. There is a 59 foot by 5 foot sump that has a bottom at 624 fo r a depth of 5 f eet. This results in a void space volume of 143.75 cubic feet which is also below th e 629 foot seasonal flood elev ation. The surface area of the walls is 5 by 5 times 2 or 50 square feet and 5.75 by 5 tim es 2 or 57.5 square feet. The three of the sump walls are 1 foot thick and one 5.75 foot long wall is 2 feet thick resulting in 136.25 cubic feet.

RS-TD-313196-002 Revision 0 Page 52 of 60 Figure 38 - Section K Side View from Drawing B-8 File Name 022940 There is a 2 foot thick interior shield wall between the stairs and the sump as seen in Figure 37. The wall is 12 minus 2 and 3 or 7 feet long. The surface area of the side walls is 49 square feet each or 98 square feet total. The surface area of the exposed 2 foot wide end is 14 square feet. The concrete volume is 98 cubic feet. There is also a 2 by 2 column 3 feet in front of the wall resulting in 56 square feet of surface area and 28 cubic feet of concrete.

As seen in Figure 38, there are als o inte rior s tairs with 10 steps between the 629 foot and 636 foot elevations. As seen in Figure 39, e ach stair has a 7 1/2 inch riser and a 10 tread. As shown in Figure 37, the stairs are 3 feet wide. This resu lts in a top su rface area of 17.5 inches or 1.46 feet per stair which equals a surface area of 1.46 by 3 tim es 10 stairs o r 43.75 square feet. The underside of the stair case may not be access ible but the surf ace area is the s quare root of the 7 foot run squared plus th e

approximately 5 2 rise where they intersect the back wall or 8.70 feet. With a 3 foot width this equals 26.10 square feet.

RS-TD-313196-002 Revision 0 Page 53 of 60 Figure 39 - Section K Side Detail of Stairs from Drawing B-8 File Name 022940 As seen in Figure 39, each stair fo rms approximately a 9 1/2 by 12 tria ngle such that each s tair has a volume of 9.5/12 by 1 by 3 feet by 0.5 or 1.18 cubic feet. There is an indent that has a volum e of 7.5/12 by 1/12 by 3 feet or 0.078 cubic feet resulting in a volume of 1.109 cubic feet per stair or 11.09 cubic feet for all 10 stairs.
