Four cases were postulated for breaks in the crossover leg piping at the base of each of the steam generators. These breaks are considered to be bounding for all loss of coolant accidentsthat could be postulated at Watts Bar.

If a high-energy line break (HELB) inside the containment were to occur, it could result in the generation of debris that, if transported to and deposited on the containment sump screens could challenge the function of the ECCS recirculation sumps. Specifically, debris that accumulates on the sump screens would cause an increase in the head loss across the resulting debris bed and sump screens. This head loss may be sufficiently large such that it would exceed the available net positive suction head (NPSH) margin of the ECCS pumps and/or could structurally challenge the sump screens.The sump screen head loss due to the LOCA-generated debris accumulated on the sump screens will be computed based on the quantity determined to be destroyed and transported.

This calculation is the first of a three step process associated with the mechanistic evaluation of the Watts Bar recirculation sump screen due to post-LOCA debris blockage. The three steps are: Step 1: Debris Generation Step 2: Debris Transport Step 3: Debris Accumulation and Head Loss This calculation shows the inputs, assumptions, and methods used to determine the type, quantity, and size distribution of debris that would be generated given various postulated break locations. The results of this calculation will be used in conjunction with the debris transport calculation to determine the types and overall quantity of debris that could reach the Watts Bar sump screens.E2-A2-9 W) Watts Bar Reactor Building GSI- 191 Debris Generation Calculation A L I 0 N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 9 of 60 No: ALIONOG 2 DESIGN INPUT This section lists the design inputs used to determine the types, quantity, and representative size distribution of debris generated by a postulated break.1) Accident Analysis a. According to the Watts Bar Updated Final Safety Analysis Report (UFSAR), the types of LOCA breaks that could lead to ECCS recirculation are defined as breaks in the reactor coolant system (RCS) piping or connected piping where the break flow exceeds the makeup flow of the charging pumps [2].b. The worst case break location is a function of the size of the ruptured pipe and the proximity to insulation that could be destroyed. The inside diameter of the primary RCS piping is 27.5" for the cold legs, 31" for the crossover legs, and 29" for the hot legs [3.14, 3.15].c. A three-dimensional computer aided drafting (CAD) model has been developed for the Watts Bar debris transport calculation. As a visualization aid for this analysis, the CAD model was extended to the operating floor based on various plant drawings. The CAD model was also used to calculate the surface area of coatings on walls, supports, and major equipment. It was also used to determine the quantity of some insulation debris as detailed in Section 4.d. Various isometric drawings were used to determine the quantity of insulation within specific distances from the postulated breaks [3].2) Debris Types and Characterization

a. Based on the Enercon developed Watts Bar insulation spreadsheet (See Attachment A), the insulation types in containment include RMI, Cal-Sil, Min-K, Interam 3M-M20C (Attachment F), Foamglass, RTV, Armaflex, Marinite, and Mineral Wool. The locations and quantities of each type of debris are specified in the insulation spreadsheet.

b. Coatings within the zone of influence (ZOI) at the postulated high energy line break (HELB) were considered.

The walkdown report [9, Attachment L] and coatings specifications (Attachment B, C, D, E) were used to determine the type, thickness, and number of coats applied.c. The density, microscopic size, and other material-specific properties were taken from the NEI-04-07, SER, vendor-specific information, or plant specific data sheets as applicable. This is discussed in detail in Section 4.5.E2-A2-1 0 0Watts Bar Reactor Building GSI- 191 Debris Generation Calculation A 0 N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 10 of 60AND TECHNO ý, DcuetNoAIN ae 1 f6 3 ASSUMPTIONS This section lists the assumptions made in the debris generation analysis.1) The nominal composition of Interam 3M-M20C insulation has a debris size distribution of 35% individual fibers and 65% particulates. (Attachment F). The fibrous component is made up of aluminum silicate and a non specified ceramic fiber. The particulates component is comprised of aluminum vermiculite (50% by weight), organic binder (7.5%by weight) and metal foil (7.5% by weight). In addition, since the majority of the 3M-M20C is vermiculite, the density of the expanded 3M-M20C insulation for the particulate component is assumed to be the minimum expanded bulk density of vermiculite, 4 lb/ft 3 with a manufactured density of 156 lb/ft 3 (Attachment F). The particulate component of 3M-M20C was assumed to fail as 10 micron particulate. The fibrous component of the 3M-M20C will be assumed to have the same debris characteristics as low density fiberglass (LDFG). The MSDS received for 3M-M20C (Interam), vermiculite and a statement for treatment of the material by Watts Bar are included as Attachment F.2) Jacketing, wire ties, buckles and straps are conservatively assumed to be the same as RMI foils and are accounted for within the RMI load as such a highly conservative RMI ZOI was used. This is conservative because RMI foils would transport more readily than the heavier metal straps, etc.3) It was assumed that the Mineral Wool, Cal Sil and RTV that reside in the crane wall penetrations would not be destroyed and will subsequently be ignored. Upon blowdown, if this material were to fail, it would be blown to the area outside the crane wall, which has no communication with the emergency sump inside the crane wall.4) In accordance with Attachment K, main steam line and feedwater pipe breaks within the reactor building penetrations are very low probability pipe breaks. As such, main steam line and feedwater pipe breaks will not be further considered in this calculation. Debris quantities generated by primary breaks are conservatively assumed to bound the debris quantities generated by secondary line breaks. This assumption is reasonable since secondary piping pressures are significantly lower than the primary piping pressure, hence the secondary pipe break ZOI will be significantly smaller than primary line breaks and will not be able to capture the quantity of pockets of 3M-M20C and Min-K that a primary break is able to. Additionally, the blowdown of secondary pipe breaks is of much shorter duration than primary pipe breaks since the secondary water/steam inventory of a steam generator and associated piping is significantly less than the inventory of the RCS.As such secondary pipe breaks inside containment will not be further considered in this calculation.

5) The Rubatex/Armaflex wrap and Foamglass insulations are closed cell insulations that reside in upper containment and in the ice condensers (Attachment H). Foamglass also resides in the raceway. Both insulations would be shielded from the LOCA jet forces and will be assumed to remain intact. This is part of the design basis of the plant (Attachment H). The Rubatex/Armaflex and Foamglass insulations are not located in any direct flow paths so failure by erosion would not be likely [3.16-3.20, Attachment H]. Even if the E2-A2-11 Watts Bar Reactor Building GSI- 191 Debris Generation Calculation L I O0N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 11 of 60 Rubatex/Armaflex or Foamglass were postulated to fail, they would be caught in the tight array of ice baskets or lattice structure in the ice condensers.

Finally, if either did transport to the pool, both of these insulation types float and they would not be a debris source which would transport to the sump (Attachment H).6) The marinite board resides in the fan room outside the crane wall and will not be subject to LOCA jet forces and will be assumed to remain intact and will subsequently be ignored.7) All coatings within the ZOI will be assumed to fail as 10 micron particulate. Unqualified coatings (alkyd, inorganic zinc, and modified silicone paint) outside the ZOI in lower containment and subject to spray in upper containment will be assumed to fail as 10 micron particulate [5].8) It was assumed that the LOCA blowdown, upon reaching upper containment, would be dry as the ice condensers condense all the blowdown steam before it reaches upper containment [ 13-17]. This along with the containment sprays being designed not to hit the containment dome liner, an argument could be made that the unqualified /undetermined IOZ on the containment dome does not fail. Notwithstanding the above, it was conservatively assumed that the IOZ on the dome above the crane wall and refueling canal would fail and contribute to the debris source term.9) It was conservatively assumed that Min-K has a bulk density of 16 lb/ft 3 as stated by the manufacturer (Attachment G). The particle densities of the Min-K components are assumed to be the same for Microtherm as there is no data for the Min-K available and both materials are microporous insulations of the same composition.

10) It was assumed that all jacketed insulation outside of the ZO7 would not undergo any erosion by either break or spray flows (i.e. no insulation debris would be generated outside of the postulated ZOIs). This assumption is considered acceptable by the NRC as stated in the SER Section 3.4.3.2 [5].11) It was conservatively assumed that the "undetermined coatings" on the pressurizer relief tank are unqualified and would fail [9].12) Transco provided sample drawings and a formal letter (Attachment J) stating the foil spacing for the Diamond Power RMI installed at Sequoyah, Unit 1 is expected to be 3 foils per inch based upon sample information.

Transco then states that "based on this sample information, it is expected that the number of liners per inch would not change throughout the four (4) projects listed" which includes Watts Bar. Personnel at Watts Bar took measurements of the RMI at random locations in containment and found the foil spacing to be 3 foils per inch. It has also been Alion's experience that Diamond Power RMI has a foil spacing of 3 foils per inch. For this analysis it will be assumed that the Diamond Power RMI installed at Watts Bar has a foil spacing of 3 foils per inch.E2-A2-12

A latent debris survey was completed at Watts Bar on 09/06 [Ref. 25]. It indicated a total latent debris load of 69.2 lbs. 200 lbs. of latent debris will be assumed to provide margin in this calculation.

SER Section 3.5.2.3 suggests that 15% of the latent debris should be assumed to be fiber, and the other 85% particulate [5]. Thus, 170 lb was assumed to be dirt/dust and the remaining 30 lb was assumed to be latent fiber.E2-A2-13 Watts Bar Reactor Building GSI- 191 Debris Generation Calculation N DocumentNo:ALION-CAL-TVA-2739-03 Rev:4 Page: 13 of 60 SCIENCf AND TECHNO D, Dou en o:L O 4 METHODOLOGY The following general steps were taken in determining the types, quantity, and size distribution of debris generated following a postulated HELB at Watts Bar: 1. The Enercon Walkdown Report [9] was used in conjunction with the Enercon provided debris spreadsheet (Attachment A) to identify and locate the quantities of insulation in lower containment (see Section 4.1).2. The CAD model was used as a visual aid to show the extent of the ZOI spheres around the postulated breaks (see Section 4.2).3. Break locations were selected based on the accident scenarios that could lead to ECCS recirculation, the size of the pipe break, and the proximity of other insulated pipes or equipment (see Section 4.3).4. The quantity of each type of debris generated was determined based on the amount of insulation that falls within the specific ZOI for that material (Attachment B), (see Section 4.4).5. The size distribution and characteristic properties were defined for each material based on the NEI-04-07 and SER methodologies, as well as applicable test data, (see Section 4.5).The debris generation analysis was carried out in accordance with Alion's quality assurance (QA) program. The program is fully compliant with 10 CFR 50, Appendix B, NQA- 1, and NQA-2 Section 2.7. It includes provisions for 10 CFR Part 21 notifications. Various area calculations were performed using AutoCAD 2006 and Inventor 10. These software packages are commercially available computer codes. The CAD software used in the debris generation analysis is configuration-controlled under Alion's QA program and has been validated and verified under the Alion QA program [22].4.1 Debris Types and Spreadsheet A spreadsheet showing the location and quantity of each type of insulation in containment was provided as design input. This spreadsheet was based on the Enercon Walkdown Report [9, Attachment A] performed in late 2004 that identified potential sources of debris: insulation, coatings and latent debris. The types of debris found in lower containment were RMI, Min-K, 3M-M20C (Interam), Cal-Sil, Foamglass, RTV, Marinite, Armaflex, and Mineral Wool. The potential coatings found in lower containment were CarbozincTM 11, CarbolineTM 295, PhenolineTM 305, and CarbolineTM 4674. The Enercon provided insulation spreadsheet was checked for accuracy and is included in this report as Attachment A.4.2 CAD Model A CAD model of the Watts Bar lower containment was developed for use in the debris generation and debris transport analyses. For this analysis, the model was used to assist in the identification of debris sources and robust barriers within a given ZOI.

Additionally, breaks that would cause a "thin-bed" effect are given consideration since these also have the potential to significantly impair sump screen performance. The following break locations were analyzed for Watts Bar: 0 0 S Break 1: Locations in the RCS with the largest potential for debris generation. Break 2: Locations with two or more different types of debris.Break 3: Locations with the most direct path to the sump.E2-A2-16 0' Watts Bar Reactor Building GSI-191 Debris Generation Calculation AoL I 0~0N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 16 of 60* Break 4: Locations with the largest potential particulate to fiberglass ratio.* Break 5: Locations that would generate debris that could potentially form a thin-bed.For debris generation, all LBLOCAs and SBLOCAs not able to be isolated from the RCS by any combination of two automatic or remotely operated isolation valves that fail to the "closed" position, or one passive component in the "closed" position must be evaluated. LOCAs involving failures of the PORVs and pressurizer safety valves do not need to be evaluated due to their ability to be neutralized as a leakage source prior to initiation of recirculation [ 19].4.4 Debris Generation As documented in NEI-04-07, the destruction pressures for various insulation materials were determined by performing air jet or water/steam jet tests. These tests were carried out by directing high-energy jets on various insulation targets at varying distances. The destruction pressures were then quantified by observing the effects of the jet on the insulation and the corresponding stagnation pressure in the flow field.In a PWR reactor containment building, the worst case hypothetical pipe break would be a double-ended guillotine break (DEGB). In a DEGB jets of water and steam would blow in opposite directions from the severed pipe. One or both jets could impact an obstacle and be reflected in different directions. To take into account the double jets and potential jet reflections, the NEI-04-07 proposes using a spherical zone of influence (ZOI) centered at the break location to determine the quantity of debris that could be generated by a given line break. Since different insulation types have different destruction pressures, different ZOls must be determined for each type of insulation. Table 4.4.1 shows the equivalent spherical ZOI radii divided by the break diameter (r/D) for each representative material in the Watts Bar containment. To calculate the ZOI radius, one only needs to multiply the pipe diameter by the r/D term. For example, the coatings ZOI has a size of 1 OD, which means that for a 20 inch pipe, the ZOI radius would be (10*20") 200 inches or 16.67 feet.Table 4.4.1 -ZOI Radii for Watts Bar Insulation Types Destruction Pressure ZOI Radius/Break Diameter Insulation Type (psi) (r/D)Protective Coatings N/A 10.0'3M-M20C (Interam) N/A 11.02 Mirror RMI 2.4 28.6'Min-K with standard bands N/A 28.62 Min-K with additional banding N/A 10.02 1) SER recommends ZOI of 10.0 r/D as a conservative estimate.2) See Section 4.5.1 3) Recommended value from SER.In some cases, if the ZOI for a particular material is very large (e.g. it has a low destruction pressure), the radius of the sphere may encounter a robust barrier and be truncated. Robust barriers, i.e., structures and equipment that are impervious to jet impingement, are assumed to prevent further expansion of the break jet. The volume of a spherical ZOI with a E2-A2-17 W .Watts Bar Reactor Building GSI- 191 Debris Generation Calculation ON DocumentNo:ALION-CAL-TVA-2739-03 I Rev:4 Page: 17 of 60 radial dimension extending beyond robust barriers such as walls or encompassing a large component such as a tank or steam generator is truncated by the barrier. The SER, Section 3.4.2.3, states that the shadow surfaces of components should be included in the analysis and not truncated. No credit was given in this report for equipment shielding (with the exception of 3M-M20C (Interam), see Section 4.5.1), however credit was given for robust barriers due to the primary shield wall around the reactor vessel and.the refueling canal.By placing a ZOI sphere centered at the break location within the CAD model, the insulated piping and equipment within that sphere can be visualized and the quantity of debris determined based on the information in the Watts Bar insulation spreadsheet [9]. For most types of insulation, it is necessary to calculate the volume or mass of debris that would be generated. However, RMI insulation is somewhat different, since it is made up of individual flat foils within cartridges. To specify the RMI debris generated, it is more appropriate to calculate the single sided foil surface area. This can be reasonably approximated using the following equation: SA=(OD+t)*zr*L*nf

• t where: SA = Single-side RMI foil surface area (ft 2)nf Number of foils per inch (thickness) in an RMI cassette OD = Pipe outer diameter (in)t = Insulation thickness (in)L Insulated length of pipe inside the zone of influence (ft)In many occasions on the received Enercon insulation spreadsheet (Attachment A) only volumetric data was reported.

The volumetric data was converted to a surface area by relating the cylindrical volume calculation above to a rectangular volume. The circumference of the pipe is held in the (OD+t)*7[ term, which can be translated to the width of the volume. The length of the pipe is held in the L term, which can be translated to the length of the volume. The thickness of the insulation is held in the t term, which can be translated to the height of the volume.E2-A2-18 Watts Bar Reactor Building GSI- 191 Debris Generation Calculation LI N O N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 18 of 60 L t Figure 4.4.1 -RMI Cylindrical to Rectangular Volume Conversion Thus, the above equation can be simplified to: SA = W

-insulation, coatings, and latent debris. In order to perform debris transport and head loss calculations, the characteristics of the debris generated must be defined. These characteristics include the size distributions and densities of the debris.4.5.1 Insulation Mirror RMI Figure 4.5.1 shows a debris size distribution plot summarizing the results of 2-phase jet tests of MirrorTM RMI [7]. This plot shows that 71% of the RMI was destroyed in 1/4-inch to 2-inch pieces, and 29% was destroyed in 4-inch to 6-inch pieces. Based on this data, the NEI-04-07 (Section 3.4.3.3.2) recommends using a size distribution of 75% small pieces and 25% large pieces, where small pieces are defined as anything less than 4 inches [4].E2-A2-19

This ZOI and distribution is based on the SER recommended destruction pressure of 2.4 psi for blanketed and unjacketed Min-K. However, at Watts Bar the Min-K is covered with the same stainless steel jacketing as RMI. Jet impingement testing was performed to determine the zone of influence (ZOI) of Min-K with additional banding (banded with 0.5-inch wide stainless steel bands at a center spacing of 6-inches) and 3M-M20C (Interam)insulation for Watts Bar Nuclear Plant. Westinghouse calculation WCAP-16783-P

[23]documents this testing and calculates the ZOI for Min-K (with additional banding) as 10.0 D.Min-K is composed of fiber, fumed silica, and titanium dioxide and has a bulk density ranging from 8-16 lb/ft 3 (Attachment G). Table 4.5.1 shows the composition and corresponding densities for MinK.E2-A2-20 (A) Watts Bar Reactor Building GSI- 191 Debris Generation Calculation N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 20 of 60 Table 4.5.1 -Min-K Composition Components % of Material Particle Particle Density by Weight Diameter (tm) (lb/ft 3)Fiber 20% 6* 165*Fumed Silica (SiO 2) 65% Varies, centered 137**at 20 Titanium Dioxide (TiO 2) 15% 2.5-10 262**Due to a lack of data and the similar composition of Microtherm and Min-K, these properties of Microtherm will be used (Attachment G).**Taken from Table 2-1 of Perry's Chemical Engineering Handbook [12]3M-M20C (Interam)This insulation is a "felt-like" material that expands when subjected to fire or high temperature, and will be treated as a high density fiberglass (HDFG) with a manufactured density of 39 lb/ft 3 (Attachment F). Upon destruction, the HDFG fines debris loses its "felt" type characteristics and becomes individual fibers in this case (see NUREG/CR-6224 size classes I through 4). As such, the HDFG fines debris will occupy a larger volume as the density of HDFG fines is significantly less than the density of the original felt material. The HDFG fines debris has been assumed to be similar to the LDFG fines debris. NUKON will be used as the surrogate of LDFG per the SER[5]. It will be assumed that it fails as 35% LDFG Nukon individual fibers (175 lb/ft 3 [20] -7 micron [5]) and 65% vermiculite (156 lb/ft 3 -10 micron [Attachment F]) particulate. In order to obtain the portion of 3M-M20C (Interam) destroyed as LDFG, one would multiply the volume of 3M-M20C destroyed by 35% and then by the bulk density (for Interam, 39 lb/ft 3)and divide by the LDFG bulk density (in this case, 2.4 lb/ft 3) [Attachment F].In order to obtain the portion of 3M-M20C (Interam) mass as particulate, one would multi!ly the volume of 3M-M20C destroyed by 65% and then by the bulk density (for Interam, 39 lb/ft).[Attachment F]Jet impingement testing was performed to determine the zone of influence (ZOI) of Min-K and 3M-M20C (Interam) insulation for Watts Bar Nuclear Plant. Westinghouse calculation WCAP-16783-P [23] documents this testing and calculates the ZOI for 3M-M20C (Interam) as 11.0 D.The application of 3M-M20C (Interam) as a radiant energy shield on conduit raceways and junction boxes confines it to a relatively centralized location within containment. The centralized arrangement and significant impact on sump performance of 3M-M20C (Interam)makes it desirable to analyze the effects of equipment shielding on debris generation quantities for this material. The SER states that the truncation of the ZOI "should be conservatively determined with a goal of +0/-25 percent accuracy, and only large obstructions should be considered." To ensure that the shielding effects are conservative, the following equation was used where only 75% of the shielded debris is credited. Appendix 5 contains the results of this analysis.E2-A2-21 Watts Bar Reactor Building GSI-191 Debris Generation Calculation L I 0 N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 21 of 60 Vold = Vol/ x (L, -(L x 0.75))L, Where: Vold = Volume of insulation destroyed Vol, = Total volume of insulation on the entire length of conduit Lt = Total length of conduit L, = Length of conduit determined to be shielded 4.5.2 Coatings Essentially all steel surfaces at Watts Bar are coated with CarbozincTM 11 (an inorganic zinc primer). All steel 6 feet from the containment floor has also been topcoated with PhenolineTM 305. The containment liner is also coated with CarbozincTM 11 [9, Attachment L] and has been left without a topcoat. Even though failure of this coating is not likely, it has been conservatively assumed to fail in this analysis as discussed in Assumption

8. The concrete floors and walls have been painted with PhenolineTM 305. All concrete below 6 feet has been painted with a CarbolineTM 295 surfacer and then painted with two coats of Phenoline 305TM [9, Attachment L]. The steam generators are coated with CarbolineTM 4674 underneath the RMI insulation.

This coating is a high temperature silicone that is not DBA qualified and will be assumed to fail as fines if the RMI that encapsulates it fails [9]. All qualified coatings outside the coatings ZOI will remain intact [5].CarbozincTM 11 -(Inorganic Zinc)The characteristic particle diameter of inorganic zinc (IOZ) was assumed to be 10 ýIm [4]. Based on the NEI-04-07 Table 3-3, the density of IOZ particulate is 457 lb/ft 3 [4]. The dry film bulk density of CarbozincTM 11 is only 223 lb/ft 3 , however. This was derived from the liquid density and other properties found on the data sheet for CarbozincTM 11 (Attachment B) as shown in the following calculation: Liquid Density = 23 lb/gal Percent Solids by Weight = 79% +/- 2% = 81%Solids per gallon = (23 lb/gal)*(0.81) = 18.6 lb/gal Spread Rate = 1,000 ft 2/gal/mil Volume per gallon = (1,000 ft 2/gal/mil)

• (0.001 in/mil)*(l ft/12 in) = 0.083 ft 3/gal Dry Density = (18.6 lb/gal)/(0.083 ft 3/gal) = 223 lb/ft 3 According to the walkdown report [9, Attachment L], the recommended application for CarbozincTM 11 is a dry film thickness of 2.5-5 mils per coat. Since this coating was used as a primer at Watts Bar, it was assumed that one coat of CarbozincTM 11 with an average thickness of 4.0 mil was applied on all carbon steel surfaces and the containment dome.E2-A2-22 0Watts Bar Reactor Building GSI-191 Debris Generation Calculation AL ION Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 22 of 60 Carboline T M 295 -(Epoxy)The characteristic particle diameter of CarbolineTM 295 was assumed to be 10 ýtm [4]. A dry film bulk density of 123 lb/ft 3 was derived using properties found on the Carboline T M 295 datasheet (Attachment C) as shown in the following calculation:

Liquid Density = 16 lb/gal Percent Solids by Volume = 68% +/- 2% = 70%Solids per gallon = (16 lb/gal)*(0.70) = 11.2 lb/gal Spread Rate = 1,091 ft 2/gal/mil Volume per gallon = (1,091 ft 2/gal/mil)* (0.001 in/mil)*(1 ft/12 in) = 0.091 ft 3/gal Dry Density = (11.2 lb/gal)/(0.091 ft 3/gal) = 123 lb/ft 3 This value will also be assumed to be the density of the particulate, as this value is higher than the 94 lb/ft 3 density recommended for generic epoxy/phenolic particulate in the NEI 04-07 Table 3-3, and is therefore more conservative with respect to debris headloss. This was applied to all floor surfaces and on the walls up to 6 feet from the floor. As up to 60 mils are required to obtain a smooth surface according to the data sheet and the walkdown report [9, Attachment L], this value will be used.Phenoline T M 305 -(Phenolic) The characteristic particle diameter of PhenolineTM 305 was assumed to be 10 ltm [4]. A dry film bulk density of 105 lb/ft 3 was derived using properties found on the PhenolineTM 305 datasheet (Attachment D) as shown in the following calculation: Liquid Density = 13.6 lb/gal Percent Solids by Volume = 64% +/- 2% = 66%Solids per gallon = (13.6 lb/gal)*(0.66) = 9.0 lb/gal Spread Rate = 1,026 ft 2/gal/mil Volume per gallon'= (1,026 ft 2/gal/mil)

• (0.001 in/mil)*(1 ft/12 in) = 0.086 ft 3/gal Dry Density = (9.0 lb/gal)/(0.086 ft 3/gal) = 105 lb/ft 3 Again, this value will also be assumed to be the density of the particulate.

According to the walkdown report [9, Attachment L], the application for PhenolineTM 305 is a dry film thickness of 4-6 mils per coat, with a single coat on steel, structures within 6' of the floor, a single coat on concrete inside the crane wall, and two coats on the floor and concrete within 6' of the floor. For this analysis, the average dry film thickness of 5-mil will be used.CarbolineTM 4674 -(Silicone) The characteristic particle diameter of CarbolineTM 4674 was assumed to be 10 ýtm. Based on the CRC Handbook of Chemistry and Physics [10], the density of Silicone particulate is 145 lb/ft 3 [4]. A dry film bulk density of 87 lb/ft 3 was derived using properties found on the CarbolineTM 4674 datasheet (Attachment E) as shown in the following calculation: E2-A2-23 W) Watts Bar Reactor Building GSI- 191 Debris Generation Calculation A -L C 0 N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 23 of 60 Liquid Density = 11 lb/gal Percent Solids by Volume = 40% + 2% = 42%Solids per gallon = (11 lb/gal)*(0.42) = 4.6 lb/gal Spread Rate = 640 ft 2/gal/mil Volume per gallon = (640 ft 2/gal/mil)*(0.001 in/mil)*(1 ft/12 in) = 0.053 ft 3/gal Dry Density = (4.6 lb/gal)/(0.053 ft 3/gal) = 87 lb/ft 3 According to the walkdown report [9], the application of CarbolineTM 4674 is a dry film thickness of 1 mil, which is the thickness that will be used for this analysis.To find the surface area of the equipment or concrete enveloped by the coatings ZOI sphere, three calculations must be made using AutoCAD. The methodology for doing this calculation can be found in the Alion Paint Surface Area Calculation methodology report [21]. However, the equation for calculating the surface area is: Coated Surface A (Areant.erseced + AreaSu btracted -AreaSphere) 2 Each of these numbers used in the paint calculation equation can be found in the paint calculation section for each break in Section 5. An AutoCAD screenshot of each of these numbers is included in Appendix 4 for traceability. Unqualified Coatings According to the SER, all unqualified coatings, inside or outside the coatings ZOI, fail. Due to a lack of data, all failed coatings must be assumed to fail as 10 micron particulate.

4.5.3 Latent

Debris Latent debris is defined as dirt, dust, paint chips, fibers, paper scraps, plastic tags, tape, adhesive, labels, fines or shards of thermal insulation, fireproof barrier, or other materials that may be present in containment prior to a postulated LOCA. Potential origins for this material include foreign particulate brought into containment during refueling outages and the normal deterioration of coatings, etc.Items such as labels, tags, tape, light-bulbs, and other miscellaneous items were identified in the walkdown report. However, no values were assigned to the quantity of these debris types.Therefore, these debris types were not addressed in this analysis. The significance of the miscellaneous debris can be addressed once the impact of the quantity of debris transported to the strainer in relation to the strainer size is assessed.A latent debris survey was completed at Watts Bar on 09/06 [Ref. 25]. It indicated a total latent debris load of 69.2 lbs. 200 lbs. of latent debris will be assumed to provide margin in this calculation. SER Section 3.5.2.3 suggests that 15% of the latent debris should be assumed to be E2-A2-24 QDWatts Bar Reactor Building GSI-191 Debris Generation Calculation A1 L IG ON Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 24 of 60 fiber, and the other 85% particulate [5]. Thus, 170 lb was assumed to be dirt/dust and the remaining 30 lb was assumed to be latent fiber.Dirt/Dust The representative size and density of dirt/dust particulate was assumed to be 17.3 jim and 169 lb/ft 3 respectively based on the SER Section 3.5.2.3 [5]. 17.3 gm is the equivalent spherical diameter of a particle that has a surface to volume ratio as noted in the SER [5].Latent Fiber The representative bulk density of latent fiber was assumed to be 2.4 lb/ft3, and the material (individual fiber) density of latent fiber was assumed to be 94 lb/ft 3 based on the SER Section 3.5.2.3 [5]. The SER does not give a characteristic latent fiber diameter, but they do indicate that it is appropriate to assume the same diameter as commercial fiberglass (7 gim for Nukon per NUREG/CR-6224). Ice Condenser Debris Watts Bar has provided a log of the debris trapped in the ice condensers which is included at the end of this report as Attachment I. The log was analyzed and separated into two groups. The items that were large and rigid would not be able to transport both out of an ice basket and through the ice condenser lattice. Items small enough to fall through the baskets to the floor will be considered debris that could be washed down through the ice condenser and are included in the list below. These items will be analyzed for transport in the debris transport calculation and will be addressed as a reduction in strainer area in the head loss calculation.

The main steam and feedwater breaks are bounded by the LBLOCA as stated in Assumption 3.4. The five different break scenarios suggested in Section 4.3 were considered. Break 1: Largest Potential for Debris Generation The largest quantity of insulation in containment is located in the RCS loops near each of the steam generators (SGs) and reactor coolant pumps (RCPs). Due to the size of the primary RCS loop piping and the quantity of insulation in close proximity to these pipes, a double-ended guillotine break of one of the primary loop pipes presents the limiting case for SBLOCAs and LBLOCAs at Watts Bar. The inside diameters of the primary RCS pipes are 29" for the hot legs, 27.5" for the cold legs, and 31" for the crossover legs [3.14, 3.15]. Clearly, a break in one of the 3 1" crossover legs would create the largest ZOI (31 in.*28.6/12 = 73.9' ZOI radius). However, depending on the exact location of various types of insulation, a break in the smaller hot or cold legs could result in the generation of a larger quantity of debris. Therefore, to analyze this scenario, the worst case break location and corresponding debris generation must be considered for all 4 loops. SER Section 3.3.5.2 advocates break selection at 5-ft intervals along a pipe in question but clarifies that "the concept of equal increments is only a reminder to be systematic and thorough". It further qualifies that recommendation by noting that a more discrete approach driven by the comparison of debris source term and transport potential can be effective at placing postulated breaks. The key difference between many breaks (especially large breaks) will not be the exact location along the pipe, but rather the envelope of containment material targets that is affected.Break 2: Two or More Types of Debris All of the breaks discussed above encompass this break scenario since multiple types of debris are present in each loop.Break 3: Most Direct Path to the Sump Since the ECCS recirculation sump is in close proximity to the RCS piping in Loops 3 and 4, a break in both of these cases would have a direct path to the sump.Break 4: Largest Particulate to Fiberglass Ratio The Watts Bar debris spreadsheet identified Min-K, 3M-M20C (Interam) and RMI within containment. Of these three types of insulation, RMI is the least problematic. RMI does not transport as easily as particulate and is not a major factor in developing headloss. Min-K is predominantly a particulate insulation material. This insulation is in various locations close to E2-A2-27 9 Watts Bar Reactor Building GSI- 191 Debris Generation Calculation ,L. J , o Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 27 of 60 the main steam lines and steam generators and throughout containment (Attachment A). There is also 3M-M20C (Interam) insulation in small areas throughout containment (Attachment A).Therefore, as the quantity of RMI is not significant and the quantity of coatings debris would be relatively the same for each break, the bounding case for each loop is which RCS break would destroy the most Min-K and 3M-M20C (Interam) debris. A thorough analysis has shown that a break in each of the crossover legs near the steam generator nozzle yields the most of these debris types.Break 5: Potential Formation of the Thin-Bed Effect This scenario addresses the generation of a small quantity of fibrous debris that, after its transport to the sump screen, could form a uniform thin bed that would subsequently filter sufficient particulate debris to create a relatively high head loss. It takes a relatively small quantity of debris to form a thin bed and is dependent on both the insulation materials and the screen size.With the exception of a small quantity of mineral wool in penetrations where it would not be destroyed and a small amount of the 3M insulation, Watts Bar has no fibrous insulation in containment. However it could be postulated that latent fiber would be transported to the sump followed by the washdown of latent particulate debris, potentially resulting in the thin-bed effect.The existing strainer area at Watts Bar is approximately 265 ft 2 as calculated from plant drawings [3]. Given this surface area, approximately 2.75 ft 3 of fiber would be required to form a 1/8" thin-bed. Note that the above thin bed comparison is for illustrative purposes only, the existing strainer is not being analyzed.The break locations that will be analyzed in this report are identified below in Figure 5.1.Figure 5.1 -Debris Generation Break Locations E2-A2-28 9Watts Bar Reactor Building GSI- 191 Debris Generation Calculation ,,.-L,.o.1o0,N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 28 of 60 5.1 Case I -LBLOCA in Loop I Figures 5.1.1 and 5.1.2 show the ZOIs for the four types of debris in Loop I for a break in the 31" crossover leg at the base of the steam generator. This was determined to be the worst case break location for this loop since it generates a significant amount of coatings and RMI debris as well as encompassing the greatest total amount of 3M-M20C (Interam) and Min-K.Figure 5.1.1 -Case I RMI E2-A2-29 OV Watts Bar Reactor Building GSI-191 Debris Generation Calculation /A L-1-ON Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 29 of 60 Figure 5.1.2 -Case I Coatings, Min-K and approximate 3M-M20C ZOI RMI According to the Enercon developed insulation spreadsheet (Attachment A), RMI is located on nearly every major pipe and piece of equipment in lower containment. As shown in Figure 5.1.1, the postulated break at the base of the steam generator would destroy most of the RMI in Loops I and 4, the RMI on most of the pressurizer, and RMI on some of the piping and equipment in Loop 2.

The equipment and lines included in the quantity destroyed are tabulated line by line in Appendix 3.Using the provided insulation spreadsheet (Attachment A) and the walkdown package [9], the spreadsheets included in Appendices 1-3 were created. These spreadsheets calculate the quantity of RMI postulated to be destroyed by using the equation defined in Section 4.4. The RMI is made up of 0.004 inch stainless steel foils, which are spaced at 3 foils per inch of panel thickness[Attachment J]. Therefore, multiplying the volumes reported in Appendix 2 by the number of foils per inch (as described in Section 4.4), a total foil surface area of 101,202 ft 2 of RMI would be destroyed. The size distribution would be 75% small pieces (75,902 ft 2) and 25% large pieces (25,300 ft 2).Min-K Most of the Min-K in containment is installed in small places on lines such as the pressurizer spray line, excess letdown lines, auxiliary feedwater line and auxiliary spray line. TVA Calculation MDQOO 10622007115 [24] details Min-K which will have additional banding installed. The Min-K ZOIs (28.6 as originally installed and 10.0 for additionally banded Min-K)were mapped in a 3D CAD model and the destroyed Min-K insulation was calculated (Appendix 3). The amount of Min-K that would be destroyed is 1.26 ft 3 (Appendix

In order to account for other steel surfaces like gratings, handrails, and miscellaneous items not included in the CAD model, this surface area was also increased by 10%(62 ft 2) to 681 ft 2.The containment dome liner is also coated with a non-DBA certified CarbozincTM 11 primer coat, therefore these coatings will also fail as fines. The dome has an 89' radius [3.19] and taking the projected area of the dome over the area inside the crane wall (radius of 57.5' [3.19])yields a surface area of 11,868 ft2 (See Appendix 4, Figure 4.52). In order to account for other steel surfaces, 10% of this total (1,187 ft 2) was added to the upper containment unqualified coatings to give a total of 13,055 ft 2.As discussed in Section 4.5.2, the thickness of IOZ paint applied to all steel surfaces is approximately 4 mils, and the applied density is approximately 223 lb/ft 3.The RMI on the pressurizer and on steam generators I and 4 will fail (Appendix

3) and is coated with CarbolineTM 4674. As the CarbolineTM 4674 coatings are unqualified, any coating exposed due to the failure of the RMI will fail. 1,007 ft2 of the steam generators was determined to be within the I OD coatings ZOI. The surface area inside the RMI ZOI and outside the coatings ZOI was determined to be 4,760 ft 2 (5,767 ft 2 -1,007 ft 2).The walkdown report specifies 0.45 ft 3 of unqualified alkyds throughout containment.

The SER recommends a density of 98 lb/ft 3 for alkyds [5]. The walkdown report specifies that the pressurizer relief tank has been coated with approximately 400 ft2 of epoxy with a thickness of 8 mil which has not been DBA certified and will also be assumed to fail [9] with a density of 94 lb/ft 3 [4].Using the calculated surface areas within the ZOI, this gives a total quantity of 1,152 lb of IOZ (182 lb+970 lb) paint, 137 lb of phenolic paint, 752 lb of Carboline 295, 25 lb of epoxy, 44 lb of alkyds, and 42 lb (35 lb+7 lb) of silicone as shown in the following calculations: E2-A2-33 W) Watts Bar Reactor Building GSI- 191 Debris Generation Calculation ON Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 33 of 60 QuantityOzLo.... -(2,446f!2)

Latent Debris It was assumed that the quantity of latent debris at Watts Bar is equal to 200 lb. SER Section 3.5.2.3 suggests that 15% of the latent debris should be assumed to be fiber, and the other 85%particulate [5]. Thus, 170 lb was assumed to be dirt/dust and the remaining 30 lb was assumed to be latent fiber. The representative bulk density of latent fiber was assumed to be 2.4 lb/ft3, and the material (individual fiber) density of latent fiber was assumed to be 94 lb/ft 3 based on the SER Section 3.5.2.3 [5]. Thus, (30 lb of latent fiber)/ (2.4 lb/ft 3) = 12.5 ft 3 of latent fiber.E2-A2-34 0 Watts Bar Reactor Building GSI-191 Debris Generation CalculationDocument No:ALION-CAL-TVA-2739-03 Rev:4 Page: 34 of 60 5.2 Case 2 -LBLOCA in Loop 2 Figures 5.2.1 and 5.2.2 show the ZOIs for each type of insulation in Loop 2 for a break in the 31" crossover leg at the base of the steam generator.

As shown in Figure 5.2. 1, the postulated break at the base of the steam generator would destroy most of the RMI in Loops 2 and 3, the RMI on most of the pressurizer and some of the RMI on the piping and equipment in Loop 1. Some of the equipment and piping in Loop 4 is on the other side of the reactor vessel and would not be destroyed. The equipment and lines included in the quantity destroyed are tabulated line by line in Appendix 3.Using the provided insulation spreadsheet (Attachment A) and the walkdown package [9], the spreadsheets included in Appendices 1-3 were created.

Therefore, multiplying the volume reported in Appendix 2 by the number of foils per inch (as described in Section 4.4), a total foil surface area of 100,293 ft 2 of RMI would be destroyed. The size distribution would be 75% small pieces (75,220 ft 2) and 25% large pieces (25,073 ft 2).Min-K Most of the Min-K in containment is installed in small places on lines such as the pressurizer spray line, excess letdown lines, auxiliary feedwater line and auxiliary spray line.

The Min-K ZOIs (28.6 as originally installed and 10.0 for additionally banded Min-K)were mapped in a 3D CAD model and the destroyed Min-K insulation was calculated (Appendix 3). The amount of Min-K that would be destroyed is 1.97 ft 3 (Appendix

The dome has an 89' radius [3.19] and taking the projected area of the dome over the area inside the crane wall (radius of 57.5' [3.19])yields a surface area of 11,868 ft2 (See Appendix 4, Figure 4.52).

3) and is coated with CarbolineTM 4674. As the CarbolineTM 4674 coatings are unqualified, any coating exposed due to the failure of the RMI will fail. 1,001 ft2 of the steam generators was determined to be within the I OD coatings ZOI. The surface area inside the RMI ZOI and outside the coatings ZOI was determined to be 5,824 ft2 (6,825 ft2 -1,001 ft).The walkdown report specifies 0.45 ft 3 of unqualified alkyds throughout containment.

Thus, 170 lb was assumed to be dirt/dust and the remaining 30 lb was assumed to be latent fiber. The representative bulk density of latent fiber was assumed to be 2.4 lb/ft3, and the material (Individual fiber) density of latent fiber was assumed to be 94 lb/ft 3 based on the SER Section 3.5.2.3 [5].

In order to account for other steel surfaces like gratings, handrails, and miscellaneous items not included in the CAD model, this surface area was also increased by 10%(62 ft 2) to 681 ft 2.The containment dome liner is also coated with a non-DBA certified CarbozincTM 11 primer coat, therefore these coatings will also fail as fines. The dome has an 89' radius [3.19] and taking the projected area of the dome over the area inside the crane wall(radius of 57.5' [3.19])yields a surface area of 11,868 ft2 (See Appendix 4, Figure 4.52). In order to account for other steel surfaces, 10% of this total (1,187 ft 2) was added to the upper containment unqualified coatings to give a total of 13,055 ft 2.As discussed in Section 4.5.2, the thickness of IOZ paint applied to all steel surfaces is approximately 4 mils, and the applied density is approximately 223 lb/ft 3.The RMI on the pressurizer and on steam generators 2 and 3 will fail (Appendix

3) and is coated with CarbolineTM 4674. As the CarbolineTM 4674 coatings are unqualified, any coating exposed due to the failure of the RMI will fail. 1,004 ft2 of the steam generators was determined to be within the IOD coatings ZOI. The surface area inside the RMI ZOI and outside the coatings ZOI was determined to be 5,598 ft 2 (6,602 ft 2 -1,004 ft 2).The walkdown report specifies 0.45 ft 3 of unqualified alkyds throughout containment.

The SER recommends a density of 98 lb/ft 3 for alkyds [5]. The walkdown report specifies that the pressurizer relief tank has been coated with approximately 400 ft2 of epoxy with a thickness of 8 mil which has not been DBA certified and will also be assumed to fail [9] with a density of 94 lb/ft 3 [4].Using the calculated surface areas within the ZOI, this gives a total quantity of 1,147 lb of IOZ (177 lb+970 lb) paint, 149 lb of phenolic paint, 836 lb of Carboline 295, 25 lb of epoxy, 44 lb of alkyds, and 48 lb (41 lb+7 lb) of silicone as shown in the following calculations: E2-A2-45 0Watts Bar Reactor Building GSI- 191 Debris Generation Calculation /c AND D, Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 45 of 60 QuantitylozLO.,e,. = (2,386ft 2)* (0.004in)

Latent Debris It was assumed that the quantity of latent debris at Watts Bar is equal to 200 lb. SER Section 3.5.2.3 suggests that 15% of the latent debris should be assumed to be fiber, and the other 85%particulate [5]. Thus, 170 lb was assumed to be dirt/dust and the remaining 30 lb was assumed to be latent fiber. The representative bulk density of latent fiber was assumed to be 2.4 lb/ft3, and the material (individual fiber) density of latent E2-A2-46 0Watts Bar Reactor Building GSI- 191 Debris Generation Calculation A,.,.. 19., N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 46 of 60 5.4 Case 4 -LBLOCA in Loop 4 Figures 5.4.1 and 5.4.2 show the ZOIs for each type of insulation in Loop 4 for a break in the 31" crossover leg at the base of the steam generator. As in the previous cases, this was determined to be the worst case break location for this loop since it generates a significant amount of coatings and RMI debris as well as encompassing the greatest total amount of 3M-M20C (Interam) and Min-K.Figure 5.4.1 -Case 4 RMI E2-A2-47 0 Watts Bar Reactor Building GSI-191 Debris Generation Calculation A-L- 11O N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 47 of 60 Figure 5.4.2 -Case 4 Coatings, Min-K and approximate 3M-M20C ZOI RMI According to the Enercon developed insulation spreadsheet (Attachment A), RMI is located on nearly every major pipe and piece of equipment in lower containment. As shown in Figure 5.4.1, the postulated break at the base of the steam generator would destroy most of the RMI in Loops I and 4 and the RMI on most of the pressurizer. Some of the equipment and piping in Loop 2 is on the other side of the reactor vessel and would not be destroyed. The equipment and lines included in the quantity destroyed are tabulated line by line in Appendix 3.Using the provided insulation spreadsheet (Attachment A) and the walkdown package [9], the spreadsheets included in Appendix 1-3 were created. These spreadsheets calculate the quantity of RMI postulated to be destroyed by using the equation defined in Section 4.4. The RMI is made up of 0.004 inch stainless steel foils, which are spaced at 3 foils per inch of panel thickness[Attachment J]. Therefore, multiplying the volume reported in Attachment B the number of foils per inch (as described in Section 4.4), a total foil surface area of 84,644 ft of RMI would be destroyed. The size distribution would be 75% small pieces (63,483 ft 2) and 25% large pieces (21,161 ft 2).E2-A2-48

TVA Calculation MDQOO 10622007115 [24] details Min-K which will have additional banding installed. The Min-K ZOIs (28.6 as originally installed and 10.0 for additionally banded Min-K)were mapped in a 3D CAD model and the destroyed Min-K insulation was calculated (Appendix 3). The amount of Min-K that would be destroyed is 1.98 ft 3 (Appendix

3) which equals 31.7 lb (1.98 ft 3

• 16 lb/ft 3) with a debris size distribution of 100% fines. This equates to 0.396 ft 3 of fiber (1.98 ft 3

[9]. The ZOI for this material envelops all of the 3M-M20C (Interam)in Loops 4 and I (Appendix 3). Equipment shielding effects were analyzed in relation to this material the details of which are presented in Appendix 5. The total amount that could be destroyed is 1.67 ft 3 (Appendix

In order to account for other steel surfaces like gratings, handrails, and miscellaneous items not included in the CAD model, this surface area was also increased by 10%(62 ft2) to 681 ft 2.The containment dome liner is also coated with a non-DBA certified CarbozincTM 11 primer coat, therefore these coatings will also fail as fines. The dome has an 89' radius [3.19] and taking the projected area of the dome over the area inside the crane wall (radius of 57.5' [3.19])yields a surface area of 11,868 ft 2 (See Appendix 4, Figure 4.52). In order to account for other steel surfaces, 10% of this total (1,187 ft 2) was added to the upper containment unqualified coatings to give a total of 13,055 ft 2. As discussed in Section 4.5.2, the thickness of IOZ paint applied to all steel surfaces is approximately 4 mils, and the applied density is approximately 223 lb/ft 3.The RMI on steam generators 1 and 4 will fail (Appendix

3) and is coated with CarbolineTM 4674. As the CarbolineTM 4674 coatings are unqualified, any coating exposed due to the failure of the RMI will fail. 1,004 ft2 of the steam generators was determined to be within the IOD coatings ZOI. The surface area inside the RMI ZOI and outside the coatings ZOI was determined to be 4,523 ft 2 (5,527 ft 2 -1,004 ft 2).The walkdown report specifies 0.45 ft 3 of unqualified alkyds throughout containment.

The SER recommends a density of 98 lb/ft 3 for alkyds [5]. The walkdown report specifies that the pressurizer relief tank has been coated with approximately 400 ft 2 of epoxy with a thickness of 8 mil which has not been DBA certified and will also be assumed to fail [9] with a density of 94 lb/ft 3 [4].Using the calculated surface areas within the ZOI, this gives a total quantity of 1,148 lb of IOZ (178 lb+970 lb) paint, 146 lb of phenolic paint, 817 lb of Carboline 295, 25 lb of epoxy, 44 lb of alkyds, and 40 lb (33 lb+7 lb) of silicone as shown in the following calculations: E2-A2-51 0Watts Bar Reactor Building GSI- 191 Debris Generation Calculation L J O N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 51 of 60 QuantityIOZL.... = (2,401 ft 2) * (0.004in)

Latent Debris It was assumed that the quantity of latent debris at Watts Bar is equal to 200 lb. SER Section 3.5.2.3 suggests that 15% of the latent debris should be assumed to be fiber, and the other 85%particulate [5]. Thus, 170 lb was assumed to be dirt/dust and the remaining 30 lb was assumed to be latent fiber. The representative bulk density of latent fiber was assumed to be 2.4 lb/ft3, and the material (individual fiber) density of latent fiber was assumed to be 94 lb/ft 3 based on the SER Section 3.5.2.3 [5]. Thus, (30 lb of latent fiber)/ (2.4 lb/ft 3) = 12.5 ft 3 of latent fiber.E2-A2-52 Watts Bar Reactor Building GSI- 191 Debris Generation Calculation kL I ON Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 52 of 60 6 RESULTS Tables 6.1 through 6.4 summarize the Watts Bar debris generation results for Cases I through 4 which all involve a break in the 31" crossover leg at the base of the steam generator.

This break location allows for the largest amount of coatings and RMI and also allows for the ZOI to envelop a large portion of the Min-K and 3M-M20C (Interam)insulation.

• The worst loop break location in regards to RMI is Loop 1. This break location (Loop 1)is also in close proximity to the emergency.

sump.* The Loop 2 break location destroys the most 3M-M20C (Interam) insulation and consequently, the greatest total fiber debris.* A break in Loop 4 destroys the greatest amount of Min-K insulation.

• All four loops generate comparable quantities of coatings debris." The destruction pressure of 2.4 psi and the corresponding ZOI of 28.6D are likely overly conservative for the Min-K with no additional banding in Watts Bar. These ZO values are for unjacketed Min-K and the installed Min-K at Watts Bar is jacketed in the same jacketing as the RMI. However, the SER instructs to use this value if no test data is available for the plant-specific jacketing.

Jet impingement testing has been conducted on the Watts Bar Min-K configuration with additional banding which shows no insulation destruction at distances beyond 10.01D.E2-A2-58 Watts Bar Reactor Building GSI- 191 Debris Generation Calculation N Document No:ALION-CAL-TVA-2739-03 Rev:4 Page: 58 of 60 8 REFERENCES

Table 5-1 "TVA Walkdown Report / 1-47A243-6-0 Reconciliation" was used to identify and aid in mapping all conduits, raceways and junction boxes listed in "Watts Bar Nuclear Plant Unit No. 1, 3M M20C Radiant Energy Shield 47A243-6-0". This table displays line items from "'Report on Watts Bar Unit 1 Containment Building Walkdowns for Emergency Sump Strainer Issues', TVAWOO I0-RPT-001, Rev 0."[Ref.9] and reconciles these items with the actual conduits from 1-47A243-6-0. The legend for Table 5-1 is as follows: This information is a line item as it is represented in the TVA walkdown report and is a "header" for the following items. For 3M insulation targets, these line items were found to summarize several different conduits, junction boxes or conduit supports into a single line item.Identified I Mapped and analyzed for shielding These items are individual conduits, junction boxes or conduit support entries as they are found in "Watts Bar Nuclear Plant Unit No. 1, 3M M20C Radiant Energy Shield 47A243-6-0". The individual items are reconciled with the TVA walkdown report and listed under the appropriate line items from that report.Identified I Duplicate target, mapped under separate line item These items are individual conduits, junction boxes or conduit support entries as they are found in "Watts Bar Nuclear Plant Unit No. 1, 3M M20C Radiant Energy Shield 47A243-6-0". Some items from this report were separated into multiple line items in the walkdown report. For the purposes of this analysis, the conduits were better left intact as a single entry. These items are identified as duplicates and the alternate item number is indicated. The individual items are reconciled with the TVA walkdown report and listed under the appropriate line items from that report.I Unidentified I Unidentified line item, conservative assumptions apply, no shielding will be credited A small number of items could not be reconciled between the two reports. These are listed in the spreadsheet and no shielding is credited for these line items. This is a conservative approach as all unmapped items are considered to be destroyed. Once the two input reports were reconciled, the items were mapped in the 3-D CAD model of the plant and each break was analyzed to determine shielding effects on the debris targets. Table 5-2 shows the results of this analysis. Per the SER, only 25% of the shielding effect is credited. An electronic copy (on CD) of the CAD model is included with this calculation as part of this Appendix.E2-A2-1 54 ALION-CAL-TVA-2739-03 Revision 4 Appendix 5 5-2 of 5-7 Table 5-1 -TVA Walkdown Report / 1-47A243-6-0 Reconciliation Identified Mapped and analyzed for shielding Identified Duplicate targlet, mapped under separate line item Unidentified Unidentified line item, conservative assumptions apply, no shieldin6 will be credited DESCRIPTION INU ItemC nt .pE A LOCATION LENGTHODFT) INSUL TYPE THICKNESS Description ToterVOLUME (FT3) Lin.

1) TVA Letter W-7929, dated May 18, 2006 Revision 3 of ALION-CAL-TVA-2739-03, Watts Bar Reactor Building GSI-191 Debris Generation Calculation, contains design input for 3M-M20C insulation that the 3M-M20C was to be treated as High Density Fiberglass (HDFG) with a debris size distribution of 55% individual fibers that is considered to expand to an assumed LDFG bulk density based upon TVA input assumptions provided in Reference 1). However, based on further review, the nominal composition of 3M-M20C has a debris size distribution of 35% individual fibers and the remaining 65% are particulates.

The non specified material is described as ceramic fiber. The non specified material and the aluminum silicate are considered fibrous. The aluminum vermiculite, metal foil, and organic binder are considered particulate. Using nominal composition values from the MSDS for 3M-M20C, the particulates are 50% vermiculate, 7.5% organic binder, and 7.5% metal foil by weight for a total of 65%. The remaining composition is 35% by weight fibrous material.Questions may be directed to C. M. Maples at 423-365-1582. Sincerely, G. W. Mauldin Site Engineering Manager EQB 2A-WBN cc: D. F.

WATTS BAR NUCLEAR PLANT UNIT 1 -CONTRACT WORK AUTHORIZATION NO. WESTINGHOUSE-WBN-2005-008-GSI 191 -CONTAINMENT BUILDING SUMP MULTIDIMENSIONAL FLOW MODEL, NRC GENERIC SAFETY ISSUE GSI-191, "ASSESSMENT OF DEBRIS ACCUMULATION ON PWR SUMP PERFORMANCE" 1. Revision 1 of ALION-CAL-TVA-2739-03, Watts Bar Reactor Building GSI-1 91 Debris Generation Calculation, contains an assumption for 3M-M20C insulation that concluded the 3M-M20C was to be treated as High Density Fiberglass (HDFG) with a debris size distribution of 100 percent individual fibers. As stated in ALION-CAL-TVA-2739-03, the HDFG fines debris has been shown to be very similar to the Low Density Fiberglass (LDFG) fines debris and therefore the terms are used interchangeably. Since the issuance of revision 1, the Material Safety Data Sheet (MSDS) for InteramTM M-20A and M-20 and M-20C mat has been obtained (Enclosure 1).The MSDS for 3M-M20C shows that the composition of the insulation is made up of 40-60% vermiculite, 10-]15% aluminum silicate, 5-10%organic binder, 5-10% metal foil, with the remaining 5-40% not being specified. Vermiculite and the metal foil are not fibrous materials and are treated as particulates. Using a conservative approach, the particulate components are minimized resulting in 45% of the 3M-M20C treated as particulates. The organic binder, aluminum silicate, and unknown material are assumed to be fibrous resulting in a maximum of 55% fibrous component of 3M-M20C. In addition, since the majority of the 3M-M20C is vermiculite, the density of the expanded 3M-M20C insulation for the particulate component is assumed to be the minimum expanded bulk density of vermiculite, E2-A2-200 4 lb/cubic feet with a manufactured density of 156 lb/cubic feet (Enclosure 2). The particulate component of 3M-M20C can be conservatively assumed to fail as 10 micron particulate.

2. The bypass fractions for fibrous and particulate insulation are a maximum of 2.42% and 62% respectively (Enclosure 3). This input is being provided for use in the "Downstream Effects Calculations", CN-CSA-05-14 (Debris Ingestion) and CN-CSA-05-36 (Fuel Evaluation).

3. The Downstream Effects Debris Fuel Evaluation, CN-CSA-05-36, also assumes that the bottom fuel nozzles capture 95% of the available fibrous debris. However, based on the analysis of the sample of debris taken in the strainer test flume (sample 1 A), the longest fiber is 3.8 mm or 0.1496 inches (Enclosure 4), which is shorter than the limiting hole size for one third of the fuel (bottom nozzles with alternate p-grid design Cycle 8 core load) but longer than the limiting hole size for the remaining two thirds of the fuel. The remaining two thirds of the fuel will incorporate the alternate p-grid design during the Unit 1 Cycle 8 (Cycle 9 core load) Refueling Outage and Unit 1 Cycle 9 Refueling Outage (Cycle 10 core load).Thus, cases should be performed to show the results of the fuel evaluation using the bypass fraction above with the additional assumption that a.) 67% of the available fibrous debris is captured on the bottom fuel nozzle and the nozzle on top of the fuel to represent the results after the Unit 1 Cycle 7 refueling outage and b.) 33% of available fibrous debris is captured on the bottom fuel nozzle and the nozzle on top of the fuel to represent the results after the Unit 1 Cycle 8 refueling outage.Questions may be directed to F.A.

8. HEALTH HAZARD DATA EYE CONTACT: See below SKIN CONTACT: EYE AND SKIN CONTACT: Fibers released during processing may cause mild irritation.

Symptoms may include itching, redness and swelling.Based on 3M studies, normal processing and handling of this product should not result in significant irritation. INHALATION: This product contains ceramic fibers and vermiculite bound together with an organic binder. Fibers and dust released during processing may cause mild, transient respiratory irritation. Symptoms may include cough and itching of the nose and throat.Certain types of ceramic fibers have caused pulmonary fibrosis and cancer in laboratory animals (IARC-2B) .However, because the fibers are bound in an organic substance, they are not likely to be inhaled during normal handling of the product in this form. Based on 3M studies, normal processing and handling of this product should not result in exposures exceeding the 3M exposure guideline for ceramic fibers. This guideline is based upon the OSHA PEL for asbestos and, thus, is believed to provide an adequate margin of safety for exposures to ceramic fibers. Total fiber concentrations in 3M operations involving cutting this product are less than 0.1 fibers per cc of air.IF SWALLOWED: Not determined .............................................................................

Perlit' hlist.tattt (1501133_Perlite has a couple of operational drawbacks. Horticultural grades of perlite can contain considerable amounts (4% by weight) of very fine particle sizes (Maronek and others 1986) that cause eye and lung irritation during mixing if the perlite is not pre-moistened. Because of its closed-cell structure, perlite has a tendency to float to According to the Container Nursery Survey, perlite is a minor component of growing media in forest tree nurseries, usually constituting from 10 to 30% of the mix. Perlite is usually added to organic components, such as peat moss, to increase aeration porosity, which is particularly important in the smaller volume containers used in container tree nurseries. Perlite grades are not standardized, but grades 6, 8, or "propagation grade" are normally used in growing media (table 2.2.13). Perlite grades are also not uniform and contain a range of particle sizes, depending on the sieve sizes used during manufacturing. 65 E2-A2-2 10 VERMICULITE MATERIAL SAFETY DATA SHEET--- SCHUNDLER COMPANY Page I of 5 MATERIAL SAFETY DATA SH EET---VERMICU LITE I.

j. Dirt/Dust

= 0.60 Ibm Assumptions

1. Average diameters and lengths of fibers are representative.

Technical Justification: This is a reasonable assumption and is based on data from NSL Labs. Further characterization of each individual fiber is very time intensive and would not be expected to produce a significant difference in the results.2. Samples 4, 5 and 6 fiber lengths and diameters are assumed to be the same length and diameter as sample 3 fibers.Page 1 of 4 E2-A2-216 Bypass Fraction Determination Technical Justification: This a reasonable assumption based on the data from samples 1, 2 and 3. Furthermore, one would expect that as fibers recirculated, the longer fibers would collect on the strainers and shorter fibers would bypass.3. Sample 3 medium fiber diameter is assumed to be 10 microns.Technical Justification: The sample 3 medium fiber is 5 microns. However, for simplicity, it is assumed to be the same diameter as sample 1 and 2 medium fibers. This is conservative since the larger diameter will result in a greater quantity of fiber bypassing and does not significantly affect the particulate bypass quantity.4. 20% of Min-K is fibrous while the remaining 80% is in particulate form (ref. 3).5. Particle density of 3M-M20C is 175 lb/IW 3 (ref. 4 and 5).Technical Justification: Since 3M-M20C is assumed to behave as Low Density Fiberglass Insulation (LDFG) in the debris generation calculation (ref. 3), its particle density is assumed to be equivalent to Nukon.6. 55% of 3M-M20C is fibrous while the remaining 45% is in particulate form.Technical Justification: The MSDS for 3M-M20C (ref. 6) shows that the composition of the insulation is made up of 40-60% vermiculite, 10-15%aluminum silicate, 5-10% organic binder, 5-10% metal foil, with the remaining 5-40% is not specified. Vermiculite and the metal foil are not fibrous materials and are treated as particulates. Using a conservative approach, the particulate components are minimized resulting in 45% of the 3M-M20C treated as particulates. The organic binder, aluminum silicate and unknown material are assumed to be 100% fibrous resulting in a maximum value of 55% fibrous component of 3M-M20C.Methodology Fibrous Debris Bypass Fraction Bypass Fraction of Fibrous Debris was determined by calculating the total volume of fibers for each sample using the fiber lengths, diameters and total number of each fiber type (long, medium, short).Volume/25 ml (ft 3/25 ml) = Total Number Fibers/25 ml * [(AL

• LL * % Long) +(AM
• LM * % Medium) + (As
• Ls* % Short)]where AL-== Cross Sectional Area Long Fiber (if)AM = Cross Sectional Area Medium Fiber (ft)As = Cross Sectional Area Short Fiber (if)LL = Length of Long Fiber (if)LM = Length of Medium Fiber (if)Ls= Length of Short Fiber (if)The total fiber volume was then converted to mass/25 ml by multiplying the volume (ft 3)/25 ml and the total material density (lb/ft 3). The material density was calculated Page 2 of 4 E2-A2-217 Bypass Fraction Determination using the particle densities of each type of fibrous material weighted by percentage of total quantity in the test.The total mass was calculated by determining the mass/min for each sample and then mass/10 min (time between samples).The strainer test was performed for a minimum duration of approximately 50 minutes which is the calculated time for the water in the flume to recirculate 5 times. The data for fibrous debris was then plotted to determine the exponential trendline equation.Integration of the trendline equation y = 8.685E-4 exp (-3.963E-2 x) from 0 to infinity gives a total quantity of 0.0219 Ibm.Using an alternative method (Riemann sums), the mass/10 min values were summed for the total quantity of fibrous debris measured in the bypass sample. However, use of the exponential trendline resulted in a greater bypass fraction and thus is conservative.

The bypass fraction is the total mass of measured fibers that bypassed the screens divided by the total mass of fibrous debris introduced upstream of the strainers-Particulate Debris Bypass Fraction A similar methodology that was used to determine the fibrous debris bypass fraction, is employed to determine the particulate debris bypass fraction.Since the samples are already given in weight, the total mass of all debris is calculated. The mass of the fibrous debris is subtracted from the total mass to give a total mass of particulate debris.Three methods could be'used to determine the total mass of particulate debris. Using a Riemann sums method, integrating a linear trendline from zero to a calculated depletion time of 69.2 min or integrating the exponential trendline from zero to infinity gives considerably different results. However, depending on the resulting application, the conservative value could be the minimum value of 39% using the Riemann sums method or 60% by integrating over the exponential trendline. The linear integrated value of 49%.particulates bypassing the strainer is provided as well. Thus, these values are determined by this evaluation with the end user responsible for determining which is the appropriate value for the applicable application. The bypass fraction is the total mass of particulate debris that bypassed the screens divided by the total mass of particulate debris introduces upstream of the strainers.

Dear Fariba,

We have completed the analysis of the seven samples submitted on December 5th using methodology, that was discussed and agred upon between NSL and Details of the method are listed below.Insoluble Solids content 1. Three 25ml portions of the well-shaken sample were extracted and filtered through a weighed .45 micron nitrocellulose filter for each individual sample.2. Sample filters were. then dried at 105 degrees centigrade for approximately 20 minutes and weighed again after cooling.3. Insoluble solid values were calculated from the weight difference for each filter and the average of the three analyses was reported.7650 Hub Parkway

Filters fibers and particles from previous test were used for the testing of fiber counts and length, 2. Preliminary light microscope observations were used to determine fiber location on the filter surface. Useful magnification is 100-200X 3. Collection of fibers was accomplished by using sticky carbon tape or other sticky conductive material. Tape was pressed against the filter and repeated as many times as needed to collect fibers fully from filter surface. Fix carbon tape on SEM stab.4. A light microscopic obscrvation of filter surface was performed to ensure complete fiber collection.

5. Tape containing fibers were examined by scanning eilctroa microscopy coupled with energy-dispersive X-ray spectroscopy (SUM/EDS) and PMS (Particle Measurement System) for count completion.

Magnification varied depending on fibers size.6. The longest and shortest fiber from each filter was measured and an average of each lass of the three samplings was reported in millimeters.

7. Each individual filter was examined and all fibers were counted with the average of the three reported for the total fiber count.Please let me know if you need any additional information regarding the analysis or the final results.Regards, David Kluk Tochnical Manager NSL Analytical Services 7O HuIb ParkwMy V Oev4d, Oh i 44"1 V OJr'; ;10-447-1550-8.00-497-6752

Because this is a composite material, the use limit is decid-ed by the lowest use limit associated with the materials incorporated into the design.Core: Maximum temperature use limit of the microporous core is a function of both shrinkage and degradation of thermal con-ductivity. At elevated temperatures, the cellular structure of the microporous insulation, which is responsible for the extremely low thermal conductivity, is compromised. The core compo-nents, including SiO 2 , particles, metal oxides and re-enforce-ment fibers, may melt or sinter together at elevated tempera-tures increasing both the solid conduction due to material con-tact, and molecular conduction of air due to the degradation of the microporous structure. Core Formulations" Mix F182 is utilized for temperatures up to 1832°F and where high vibration environments are seen." Mix F150 is used for applications at 1200°F and lower.Cloth: Cloth selection is based on the maximum temperature use limit required by the application, but may also be determined according to other physical characteristics such as rigidity, permeability or durability. Some cloths (Nextel) are also used due to their qualification as an industry approved fire barrier.The maximum temperature use limit is based on the degra-dation of the strength of the material. Some cloths are rated for higher temperature use in other industries, the use limits here reflect the survivability of the Min-K product in demand-ing aerospace environments." 2116 E-Glass -Maximum use limit of 500OF (in harsh aero-space environments) used in 501 series of materials or Standard Flexible Min-K."

The particulate and fibrous material are sized to create pores which are <0.1um in diameter, less than the mean free path of air. By limiting quantity and motion of air particles in the pores, both conduction due to air and con-vection heat transfer is limited, thus reducing the thermal conduc-tivity. This is the basis of microporous insulation. At lower densities there may be insufficient material to create the very small pore structure, resulting in larger pores more capable of efficient transfer of heat and increased thermal conductivity. As the density of the microporous insulation decreases from 16 pcf, the thermal conductivity increases. Min-K materials are engineered to provide the optimum thermal efficiency while maintaining product handling characteristics and cost.Note 1. Density greatly affects the compression resistance of the material.Note 2. Product density refers to core material and does not incorporate the cloth facings.Thickness Considerations Flexible Min-K501' Flexible Min-K 12012 Flexible MIn-K 1801, 8 10 16 8 10 16 8 10 16 The insulating capabilities of microporous insulation increases with increased thickness until a point of diminishing returns is eventually reached, above which added insulation provides only a marginal benefit.Adding layers of insulation, in l/k" increments can substantially reduce cold face temperatures. For a more accurate representa-tion of your specific application, please contact your Thermal Ceramics Sales Representative. Flexible Min-K is a composite of both a lower thermal conductivity microporous core and a higher thermal conductivity high tempera-ture textile, as overall product thickness increases (while textile thickness is maintained) the composite thermal conductivity will decrease.Flexible MIln-K-6pcf Cold Face Cold Face Cold Face Thickness, In.

Due to the surface chem-istry of the fumed silica, it absorbs moisture either through contact with water, fluids, or humidity in the air. When direct contact with fluids occurs an irreversible, catastrophic degradation of the micro-porous structure occurs, which degrades the low thermal conduc-tivity of the material. Upon drying, it will not be restored.Flexible Min-K submerging water tests (5 minutes) and then allow-ing it to dry results in approximately a 35% increase in thermal conductivity.Testing has shown that when exposed to an environ-ment of 75% humidity for 8 hours Flexible Min-K experienced a weight gain of <5% and an increase in thermal conductivity of approximately 4%. The effects of moisture may become a concern where high humidity and heat for long duration exist.1. F150 core, E-Glass facing, 8,10,16 pcf density 2.

This is by weight. The material will not break down entirely, but rather it will break into agglomerates if in a very high shear situation. I don't have the specific gravity data with me, but it is all the same as you would find for those materials in a CRC handbook. We don't have a lot of data on destructive testing, as our Flexible product, which I think is the material that interests you, doesn't really fail within the applications that it is often times used. The vibration tests are generally what are the most challenging (rather than MOR or something of that nature which tends not to apply), and the mode of failure on that test is associated with the breakage of the textile or threads, rather than the core. There is a theory that I have read on this material, though I don't know if it is of any use to you. However, the thought are that each time an aircraft takes off or lands (time during which vibration is the most extreme, the core essentially breaks apart a little. However, because the bonding mechanism is simply OH- bonds, the core re-bonds during times of low vibration. This was a considerable benefit our material has over fiber products which will simply break over time, and hence break down.I am out of the office today, but can be reached at 574-596-3694 if you need anything immediately. Otherwise, I will give you a call next week to discuss any other issues.Thanks, Ken----- Original Message -----From: Wilkens, Daniel J [1] Sent: Wednesday, September 15, 2004 1:34 PM To: kvannimwegen @thermalceramics.com

RE: Properties of Min-K Ken: My name is Daniel Wilkens, and I am a colleague of Tim's.

RE: Properties of Min-K Tim, The as-fabricated density of our product varies with thickness and shape, which is why we tend to provide the core density rather than as-fabricated. With that said, I have attached a TechNote which provides you with the basis weight (mass/area) of our most commonly used flexible products.Several materials are used in our core product including Si02 particles, which are sized from 0.01-0.015 microns, TiO2 which is sized at less than 5 microns, and fiber products, most of which are between 2.5-10 microns in diameter.You may also be interested to know that we have two specific formulations which contain an additive to allow us to pass NRC 1.36.Regards, Ken Van Nimwegen----- Original Message -----From: Sande, Timothy D[4] Sent: Wednesday, September 01, 2004 3:45 PM To: Min.K@thermalceramics.com

RE: Seeking technical support

Dear Mark,

It sounds as though Daniel is working on a calculation of settling rates for the material if completely dispersed in water.If completely destroyed, Microtherm would revert to the particle sizes of the constituent materials. Broadly speaking, Microtherm Super G is composed of filaments, fumed silica, and titanium dioxide in proportions of 3%, 58%, and 39%. We usually supply Super G into the nuclear industry but it is worth checking this in case it is Super G hydrophobic, which will float.The filaments are 6 mm long and 6 microns in diameter. Specific gravity is approx 2.65 g/cc.The titanium dioxide is irregular but broadly spherical, particle size centred around 2.5 micron, specific gravity 4.2 g/cc.The fumed silica is a bit more complex, as it is formed of spherical primary particles fused together into irregular three dimensional branched chain aggregates which are further mechanically entangled into approximately spherical porous agglomerates. The agglomerates are centred very roughly around 20 microns diameter and have a specific gravity of around 0.06 g/cc (in air). I think for these purposes the agglomerates can be regarded as the fundamental particle, because it takes a great deal of dispersion energy in a high shear mixer and the use of dispersants to break the agglomerates down to aggregates. Cabot or Degussa are the manufacturers of fumed silica and could probably offer more information if required. The behaviour of fumed silica in liquids is complex because it tends to form a cross linked gel in many circumstances. If the Super G is supplied as naked block, it will have a packaged density of 350 kg per cubic meter (0.35 g/cc). If it is supplied as glass cloth covered panel it will have a packaged density of 240 kg per cubic meter (0.24 g/cc).I hope this answers your questions. Please give me a call if you need any more info.Best regards-Mark Dr Mark Mortimer Manager, Materials Research Group E2-A2-245 Calculation No. SD-0023 Page F2 Revision 0 Direct Dial: +44 (0)151 6066211 Business Fax: +44 (0)151 606 6216 e-mail: mmortimer@microtherm.uk.com MICROTHERM INTERNATIONAL LTD., 1 Arrowe Brook Road, Upton, Wirral CH49 1SX, UNITED KINGDOM----- Original Message -----From: Mark Burton Sent: 15 September 2004 14:30 To: Mark Mortimer Cc: Geoff Carr; Jeroen Goetschalckx

Over elbows, the outside surface is composed of-flat sections in the shape of rectangles or the outside and -inside. bends of the elbow, and in the, shape of trapezoids on the elbow sides. The largest stingle flat outside surfaoe area of the insulation coveringKan elbow is 6,88 square feet. In oross seotiont eseotion end has a parting surface area of 1.79 square feet and the, longest straight length has a parting surface area in the longitudinal direction of 2.0 square feet.-The sump is located beneath the refusling canal. to provide proteotion from high energy piping failures. Additionally the area around the sump is enclosed on two sides by concrete walls and on two sides by walls consisting: of structural steel and 1/4-Inah mesh backed by I 1/2-inah grating; Considering the curvature or the insulation over straight portions of the primary system piping and the angolarity of the.insulation over elbows, and the quantity of equipment and supports anchored to the containment floor that would prevent movement of settled insulation sections, the maximum. possible screened area that could be blocked is very small. Any contact between an insulation section and the screen wall, would' most probably -be along a line or at a point in the-unlikely event that some of the mirror insulation were to fall against the. screen. wall. :Sinde the insulation covering one elbow together with the insulation covering one straight length of piping iS all that.could, be affected by a given break, there is only one outer flat surf'ace of insulation available to contact the Screen wall.

The total area blocked by thes- #;wo sections of mirror insulation would be 8.88 square feet of the .. o screen area of P659.9 3quare feet.

Dear Mr. Rogers:

In response to your Letter No. 30M518 dated May13, 2005, we have conducted a preliminary review of the Diamond Power design and manufacturing drawings for the reflective metal insulation provided under the Purchase Orders referenced in the letter. While the requested information was not included on the insulation design/assembly drawings, a review of the manufacturing drawings for the following sample component insulation panels established the following information. SeaqOvalh Unit 1 Reactor Coolant Pump 2.66" actual insulation thickness with 3 foil liners/inch Pressurizer 4.00" actual insulation thickness with 3 foil liners/inch Based on this sample information, it is expected that the number of liners per inch would not change throughout the four (4) projects listed in your letter.However, confirmation of this expectation will require a concerted effort to retrieve and review all of the insulation manufacturing drawings for the primary components (Le., reactor vessel, reactor coolant pumps, steam generators and pressurizer) and all piping greater than 3" in diameter (i.e., main steam, main feedwater, pressurizer surge, residual heat removal letdown, cold leg accumulator, safety injection, primary system hot/cold legs and crossover legs) for all four plants.If TVA requires confirmation of the manufacturing information for all the insulation provided for the four plants, please advise us accordingly and we will provide a resource and schedule estimate for the data retrieval and review.A CORPORATION OF THE TRANSCO.

The analysis involves quantifying the amount of debris generated during certain postulated piping system breaks inside the reactor containment buildings and evaluating the effect of the debris on the ability to recirculate fluid collected in the containment building sump for post event reactor core cooling.In quantifying the amount of debris generated under accident conditions fbr this analysis, we have reviewed the reflective mctal insulation originally supplied by the Diamond Power Specialty Company under the subject contract for primary system equipment and piping systems located inside the reactor containment building. To support completion of the debris generation calculation, the following information is required to characterize the type and quantity of debris generated by the impact of a high energy pipe break on insulation supplied by Diamond power.1. The number of reflective metal foils per inch of insulation thickness.

2. The average thickness of the reflective metal foil.We have reviewed the documentation file for the subject contract and have not been able to locate this information.

To support the TVA analysis, please provide the information outlined in Items I and 2. aLbove for the Diamond Power reflective metal insulation provided for Sequoyah and Watts Bar under the subject contract.-E2-A2-273 WlAY 13 M05 Transco Products Incorporated Page 2 The insulation involved in this request was provided under the following Diamond Power Purchase Orders.Purchase Order Plant 590009-R Sequoyah Unit I 590009-R Watts Bar Unit I 590026-R Sequoyah Unit 2 590027-R Watts Bar Unit 2 Please review the above request and provide a written response.

WESTINGHOUSE-WBN-2005-008-GSI 191 -CONTAINMENT BUILDING SUMP MULTIDIMENSIONAL FLOW MODEL, NRC GENERIC SAFETY ISSUE GSI-191,"ASSESSMENT OF DEBRIS ACCUMULATION ON PWR SUMP PERFORMANCE" Watts Bar Nuclear Plant's licensing basis is such that a break is not postulated to occur in Main Steam System or Feedwater System lines at the locations where guardpipes are provided when penetrating the crane wall, containment vessel and shield wall. Section 3.6 of the FSAR discusses the analysis methodology and postulated break locations and is analyzed in accordance with NUREG-0800 Section 3.6, Branch Technical Position MEB 3-1. Therefore, a break inside the guardpipe for the Main Steam System piping and Feedwater System piping should not be used to characterize the event for which potential sump blockage could occur.Watts Bar Nuclear Plant feels it prudent to consider a sensitivity analysis for a Main Steam Line Break outside of the guardpipe. E2-A2-276 Krish Rajan Page 2 May 26, 2005 TVA will provide to the NRC the justification for taking an exception to a break in the Main Steam System and Feedwater System lines where protected by guardpipes between the crane wall and shield wall.Questions may be directed to F.A.

Re: Watts Bar Coatings... Joe: Here's what I've got. The info below is based on TVA Drawing 46W466-1 Rev. 23 and TVA General Construction Specification G-55 (various revisions).

1. The coatings on the steel support structures All steel was shop or field primed with Carboline Carbo Zinc 11, 2.5 -5.0 mils DFT. The entire liner plate, and all steel to a dado height of 6' from the lower containment floor were topcoated with Carboline Phenoline 305 4.0-6.0 mils DFT. The Upper Containment Dome was left untopcoated (primer only).2. The coatings on the concrete inside the crane wall Concrete floors: Carboline 295 Surfacer 40-60 mils DFT Carboline 305 intermediate coat 4.0-6.0 mils DFT Carboline 305 topcoat 4.0-6.0 mils DFT Concrete Walls up 6' dado height from the floor: Same system as floors 3. The coatings under the insulation on the crossover leg and main steam lines (if any)I can't find any indication that any coating was applied to these surfaces.4. The coatings on the RCPs According to TVA Nonconformance Report 8633 dated 7/1/87, the RCP motors were coated by Westinghouse with and unqualified system: Ameron Dimetcoat 2 Inorganic Zinc Primer Ameron Amercoat 66 Epoxy Phenolic Topcoat No DFT's were given, but you can assume the primer at 2.5-5.0 mils and the topcoat at 4-6 mils.5.

These ZOI values are for unjacketed Min-K and the installed Min-K at Watts Bar is jacketed in the same jacketing as the RMI.However, the SER instructs to use this value if no test data is available for the plant-specific jacketing.
