1.0 INTRODUCTION

Boraflex is a neutron absorber material used for criticality control in some spent fuel racks. Premature deterioration of this material, via slow dissolution of the residual matrix, has been observed in some racks.[1' 2 ,31 The Boron-10 Areal Density Gage for Evaluating Racks (BADGER) was developed by Northeast Technology Corp. (NETCO) for the Electric Power Research Institute (EPRI) under research project WO-3907-01. 5 BADGER is a device which allows the in-situ measurement of the boron-1 0 areal density ( 10B density expressed as grams 10 B/cm 2) of the neutron absorber material installed in spent fuel racks for the purpose of reactivity control. The development of BADGER was prompted by the observed in-service deterioration of Boraflex, as noted above. This report describes the BADGER test conducted at Florida Power and Light Company's Turkey Point Nuclear Station Unit 4 April 30 through May 7, 2010. The testing was performed following NETCO Products and Services Division of Scientech, Special Engineering Procedures: SEP-346-01, Revision 0[6] and SEP-346-02, Revision Previous BADGER testing had been performed at Turkey Point Nuclear Station, Unit 3, in November of 2000,[s] March of 2004,[9' and March of 2007.[10, Prior to the current campaign at Turkey Point Unit 4, Florida Power and Light updated the RACKLIFEH 111 model (Version 2.0) of the Turkey Point Unit 4 spent fuel pool 1

racks[ 2]. RACKLIFE provided a means to identify those storage cells and specific Boraflex panels that had been subjected to the most severe service histories in terms of accumulated gamma exposure and, potentially, boron carbide loss. Based upon RACKLIFE results, Florida Power and Light selected 69 panels for testing, covering a range of service history representative of Region 2 of the spent fuel racks, and provided NETCO with a list of these panels. These panels included some with the greatest gamma exposure (- 3.6.1010 rads) in the pool.

The following sections of this report provide an overview of the BADGER equipment, the test data from the Turkey Point Unit 4 campaign, an evaluation of that data including the measured areal densities, comparison with the previous test campaign, and NETCO's conclusions with respect to the condition of the Boraflex in the Turkey Point Unit 4 spent fuel racks. The RACKLIFE model provides a means for forecasting the rate at which each panel of Boraflex accumulates gamma exposure, and therefore provides the means for evaluating and implementing rack management strategies and to mitigate the effects of Boraflex degradation.

NET 346-01 2.0 OVERVIEW OF THE BADGER SYSTEM 2.1 BADGER Equipment Description Figure 2-1 schematically depicts the deployment of the BADGER system. When in use the system is suspended from the spent fuel bridge crane. The bridge and crane are used to position the equipment in the x-y direction for the purpose of moving BADGER over specific storage cells for testing. The areal density gage is lowered in and withdrawn from a specific cell via the drive system. The drive system is comprised of a stepper motor, gear box, and winch assembly which remotely raise and lower the BADGER hardware. Also included on the drive platform are a shaft encoder which provides a precise measure of the axial elevation of the BADGER hardware, and a load sensor which trips the drive motor should the hardware hang-up in a cell.

The BADGER hardware consists of a set of stainless steel suspension poles and the aluminum source and detector heads that are suspended by the poles. Figure 2-1 shows an axial cross section of the source and detector heads positioned in two adjacent storage cells. The source and detector heads consist of aluminum boxes with tapered lead-ins on the bottom surface. The tapered lead-ins guide the device as it is inserted into the storage racks.

Figure 2-2 shows a lateral cross section of the source and detector heads. The detector head contains a stainless steel block, mounted on one inside face of the head, that houses four two inch high BF3 detectors. The detector block is shielded on all sides by 0.08" thick Boral sheeting to prevent neutron back scatter to the detectors. There is a two-inch "window" of standard aluminum aligned with the detectors facing the source head. This strip extends the width of the detector block to permit streaming neutrons to enter the detectors. The detectors are encapsulated in watertight enclosures that are sealed to the waterproof detector cables. The source head contains a watertight aluminum tube which houses a 252Cf source when the equipment is in use.

The principle of BADGER operation is based on the attenuation of neutrons through the Boraflex panel between the source and detectors. High-density polyethylene in the source head thermalizes a portion of the fission neutrons produced by the 252Cf source.

The number of thermal neutrons reaching the neutron detectors is a function of the number of boron-10 atoms (10 B areal density) in the Boraflex panel between the source and detectors. The magnitudes of the detector signals, in turn, are a function of the 10B areal density in the Boraflex panels. For panels with high areal density, the detector signals are low, whereas for low areal densities the signals are high. BADGER is calibrated by passing the source and detector heads through a custom designed 3 x 3 calibration cell (see Figure 2-3) containing sections of Boraflex with known luB areal densities.

Attachment 1 2 PTN-ENG-SEFJ-10-012 Rev. 0 Page 8 of 129

NET 346-01 The detector signals are fed to four pre-amplifiers that are mounted on the drive assembly. Shielded cables connect the preamplifiers to four amplifiers in an electronics console positioned alongside the pool. The electronics console also houses a power supply used by the amplifier, pre-amps, and detectors. The amplified detector signals are fed to a special counter board in a laptop computer for counting and recording. The computer serves as a data-logger and as a control unit for the stepper motor and positioning encoder.

2.2 Typical Operation of BADGER The BADGER system is applied to measure the 10B areal density in spent fuel racks as follows. First, a special calibration cell is lowered into the pool, typically near the racks to be measured. After the equipment has been assembled poolside and suspended from the spent fuel bridge crane, the source and detector heads are submerged in the 5ool so that the top of the source tube is just above the pool surface. At this point, the 2Cf source is transferred into the source tube, a seal plug is installed, and the BADGER probe (source and detector heads) is lowered into the pool.

The Turkey Point Unit 4 calibration cell is a 3 x 3 array of storage cells containing various Boraflex panels of known boron-10 areal density and is designed to provide an accurate representation of the actual Region 2 racks. Figure 2-3 shows a schematic of the calibration cell. The calibration cell is constructed of four 0.075 inch stainless steel side walls containing a U-channel welded to each at the mid-plane, which forms a storage box. Each U-channel has a sheet or section of Boraflex material adhered to each side with Dow Corning 732 silicone adhesive. The measured Boraflex (and Boral) panel areal densities are listed in Table 2-1. Figure 2-4 shows the poison panel location within the 3 x 3 calibration cell. The reference panel in this calibration cell is a Boraflex panel representative of the panels of the Turkey Point 4 Region 2 racks.

The areal density of a Boraflex panel is determined by comparing the detector count rate through the panel to the count rates through panels of known areal density in the calibration cell. For example, in a Boraflex panel that has thinned due to dissolution of the residual Boraflex matrix, a higher detector count rate is recorded. The amount of thinning is determined by comparison with a fit of the standards in the calibration cell.

The absolute areal density in a panel is determined by constructing a fit of the form:

B-10 = m(InT) + b where: T = neutron transmission B-10 = boron 10 areal density m = slope b = intercept with the ordinate Attachment 1 3 PTN-ENG-SEFJ-10-012 Rev. 0 Page 9 of 129

NET 346-01 The slope (m) and the intercept (b) of the curve in the above equation is determined by measuring T, the neutron transmission for the calibration cell with standards with known areal density between the source and detector heads. The constant b is determined by measuring T in the reference panel of the calibration cell.

A Boraflex panel is tested in the following sequence. The probe (source and detectors) is placed into two adjacent cells on either side of the Boraflex panel of interest and lowered to the bottom of the cell. A load sensor on the lift assembly provides indication of when the probe is fully inserted. The reference elevation datum is established at the bottom of the cell and all measurements of probe elevation are relative to this datum.

(When analyzing the data the elevation is subsequently adjusted to be relative to the bottom of the Boraflex panel according to as-built manufacturing drawings.)

The entire panel is scanned with the heads being moved in two-inch increments from the bottom of the cell to the top. The active portion of the detectors is two inches so a scan measurement represents complete axial coverage of the panel. At each elevation, the counts of each detector are measured for a period of 8 seconds in the Region 2 racks, and are recorded by the data-logging computer. As the scan proceeds, the test equipment operator monitors the CRT of the computer as the counts are plotted on the screen as a function of axial elevation. The operator monitors the elevation data, where high count rates could be indicative of low boron-10 areal densities or gaps in the Boraflex panel. After the scan is completed, the BADGER heads are moved so that they are flush with the top of the cell. Measuring the BADGER elevation here provides an additional datum to measure elevation in the cell. After the elevation measurement is complete, the probes are moved out of the tested cells and to a new location for subsequent testing.

The process is repeated for subsequent panels scheduled for testing. The total time required for a scanning measurement is typically one half hour per panel in the Region 2 racks. As data is recorded by the data logging computer, data files containing detector count rates versus axial elevation in the cells are created on the hard drive which serves as a permanent record of the measurements.

NET 346-01 3.0 SCOPE OF THE TESTING AT TURKEY POINT UNIT 4 3.1 Spent Fuel Rack Description The spent fuel racks at Turkey Point Unit 4 consist of two regions as shown in Figure 3-

1. Region 1 is designed for high reactivity unirradiated fuel and consists of three modules (modules 10, 11, and 12), providing a total of 324 storage locations. Region 2 is designed for depleted fuel and consists of nine modules (modules 1-9) of varying size for a total capacity of 1124 storage cells. The current testing campaign was limited to Region 2 panels only.

Although testing was limited to Region 2, a description of the Region 1 cells is provided for added detail. The Region 1 storage array is a flux trap configuration with two sheets of Boraflex separating each fuel assembly as shown in Figure 3-2. The basic structure of this storage array is a square stainless steel tube 0.075 inches thick with an 8.75 inch inside dimension and 165.6 inches in length. Each of the structural tubes has one sheet of Boraflex 141.4 inches long, 7.5 inches wide, and 0.078 inches thick (nominal) positioned on each of the four outside faces. During manufacture, the Boraflex sheets were first attached to 0.020 inches thick stainless steel wrapper plates via a Dow silicone sealant that was used as an adhesive. The wrapper plates were then resistance welded to the structural cell wall. The welds are located at approximately 6.75-inch intervals along each side of the cover plate.

To complete the Region I rack module assembly, the structural tubes with Boraflex and stainless steel wrapper plates are welded together at the top and bottom to a stainless steel frame and a lower base plate. This creates the flux trap configuration with a 1.38-inch (minimum) water gap between adjacent storage cells. Each cell has a lead-in at the top to guide fuel assemblies into the cell. The base plates of each module are fitted with leveling feet that rest on the pool liner.

In the design of the Region 2 racks, credit is taken for fuel burnup so that only one sheet of Boraflex separates each fuel assembly. The individual Region 2 storage cells are formed by creating a checkerboard configuration of square tubes as shown in Figure 3-

3. The basic structure of this storage array is a square stainless steel tube 0.075 inches thick with an 8.8 inch inside dimension and 165.6 inches in length. Each structural tube has one sheet of Boraflex 141.4 inches long, 7.5 inches wide, and 0.048 inches thick (nominal) positioned on each of the four outside faces.1121 Attachment of the Boraflex is similar to that of Region 1 except that resistance welds are located on approximately 7.0-inch centers along the length of the wrapper plate.

To complete the Region 2 rack module assembly, the structural tubes with Boraflex and stainless steel cover plates are welded together at the corners and to a bottom base plate. In this manner every other storage location is formed by the structural tube, and

the alternative locations are formed by the four adjacent faces of neighboring structural Attachment 1 10 PTN-ENG-SEFJ-10-012 Rev. 0 Page 16 of 129

NET 346-01 tubes. The base plates of each module are fitted with leveling feet that rest on the pool liner.

3.2 Boraflex Panels Selected for Testing A RACKLIFE 2.0 model of the Turkey Point Unit 4 racks and pool was developed and implemented by Florida Power and Light Company. This model was used to estimate the actual service history of each panel of Boraflex in the Turkey Point Unit 4 storage racks, including accumulated gamma exposure and B4 C loss. The model included information regarding the predicted state of the pool at the time of testing. Figure 3-4 shows the predicted distribution of panel dose for the Turkey Point Unit 4 racks.

Sixty-nine panels from Region 2 were selected for testing by Florida Power and Light Company. The panels selected for testing are listed in Table 3-1 along with the RACKLIFE predicted dose.113 1 In the Region 2 racks, the panel tested with the highest gamma dose is S39E with an exposure of 3.6-1010 rads.

Accumulated dose is a necessary but not a sufficient predictor of panel boron carbide loss. Panels that received a moderate dose many years ago may currently indicate more dissolution than a panel that received a higher dose more recently. Once a critical dose threshold has been achieved (about 5.108 rads) Boraflex becomes susceptible to dissolution by the pool water. The Boraflex dissolution reaction is an equilibrium reaction that is dependent upon the reactive silica concentration in the volume of water in contact with the Boraflex. Accumulated dose beyond the critical dose value has little additional effect upon the dissolution of the panel. Dissolution at this point is mostly due to the interaction of low silica concentration pool water with the high dose panel. Panel dissolution can, therefore, be strongly dependent upon panel cavity volume, water exchange rates with the panel cavity, and pool currents. The RACKLIFE code predicts the B4 C loss from Boraflex based on the kinetics of this silica dissolution.

A normalized transmission is determined by calculating the average detector count rate in the Boraflex away from gaps and other anomalies, and plotting the deviation from this average. A normalized transmission trace shows deviations from a condition of uniform loss. Thus deviations from the zero line represent a combination of the effects of counting statistics, shrinkage induced gaps, and local differences from a uniform panel boron carbide loss. A flat trace is not indicative of zero dissolution, only that the dissolution is uniform along the panel. The salient features of a few of these traces are described below to aid the reader in interpreting the traces in Appendix A.

(Note: Detector 1 traces for panels B7E, B7N, C6N, C6S, C6E and C6W appear as a flat line due to spurious motor noise on detector 1. Areal densities for these panels are based on detectors 2, 3 and 4.)

Figure 4-1 contains a plot of the four normalized transmission traces resulting from a scan of Region 2 panel V53 West. The detector count rates for detectors 1 and 2 along the first fifty inches indicate some local thinning. This panel is relatively intact; however, a small amount of uniform panel thinning is evident.

Panel V53 West can be contrasted with normalized detector traces for panel U37 West in Figure 4-2. This panel has elevated count rates at the bottom and top ends indicative of end dissolution or shrinkage. The bottom fifty inches shows a variation in count rate on all four detectors indicative of uniform panel thinning. There are also four gaps located at 70, 92, 128 and 140 inch elevations.

Figure 4-3 shows the normalized detector transmission traces for panel V34 North.

Some panel thinning is occurring below fifty inches, with a higher degree of dissolution occurring below the crack on detector one. This crack is approximately 90 inches above the bottom of the panel. This is likely a result of an increased flow path along the detector 1 side of the panel, where the water can exit at the gap.

Figure 4-4 illustrates increased panel thinning along the length of panel V38 South. The count rates at the bottom of the panel are below the normalized transmission line, indicating the presence of accumulated boron carbide. As the elevation increases, the count rates increase, particularly on detector 4, showing an increase in panel dissolution along that side of the panel.

The detector traces for panel V38 North shown in Figure 4-5 are an example of a panel with numerous small cracks along the length of the panel along with two gaps at 62 and 102 inch elevations.

NET 346-01 Figure 4-6 shows an example of end dissolution along the bottom of detector 1 in panel U37 East. This is likely the result of the corner below the gap at 6 inches dissolving and the boron carbide settling to the bottom, causing the initial drop in count rate. There are also two small gaps at 42 and 50 inches.

Figure 4-7 shows the normalized transmission trace for panel S39 East. This panel had the highest absorbed dose of 3.6.1010 rads. Two large gaps occur in this panel, with the largest being nearly 2 inches wide. One gap is seen at the 33-inch level. A second gap is seen at the 125-inch level and has some dissolution around the bottom edge of the gap.

4.2 PanelAverage Areal Density Based on a quantitative analysis of the BADGER data the panel average boron-10 areal densities have been computed. The panel areal densities were computed based upon a reference panel (2B) areal density of 0.0155 gms B-1 0/cm 2 .

Figure 4-8 contains a plot of BADGER measured non-gap areal density versus RACKLIFE predicted dose for the Region 2 panels tested. In addition to the measured value, the measurement uncertainties are also shown. These error bars represent the combined measurement uncertainty due to BADGER measurement uncertainty and statistical uncertainty associated with the areal density calculation for each panel. The BADGER measurement uncertainty is determined experimentally by twice scanning a given panel. Their fractional deviation in areal density, K, is used, along with the statistical uncertainty, cy, to determine the total uncertainty in areal density(6p):

(p= Kp+o-For further explanation of uncertainty (1a) calculations, see Appendix C.

The dashed curves in Figure 4-8 represent the minimum certified areal density (0.012 gms B-1 0/cm 2), this value corrected for densification and the 50% minimum certified areal density also corrected for densification. The areal density of irradiated Boraflex actually increases up to about 1.0.1010 rads due to an increase in density assuming no dissolution. Four panels are less than the minimum certified areal density, but within the measurement uncertainty. As noted in Section 3.2, both gamma exposure and time of exposure are factors which influence panel boron carbide loss, so a strong correlation with dose is not necessarily expected.

Table 4-1 shows the measured areal density for the Region 2 panels tested. Two values of areal density have been computed for each panel. The first, the non gap areal density is the panel average areal density as measured away from panel gaps. The second, which includes gaps, is the panel average areal density calculated over the entire length of the panel including gaps. In a panel with gaps the former is greater than the latter. In a panel without gaps the two are equivalent. Table 4-1 also shows the Attachment 1 19 PTN-ENG-SEFJ-10-012 Rev. 0 Page 25 of 129

NET 346-01 number of gaps in each panel, the size of the largest gap, cumulative gap, total amount of panel dissolution along each panel, and the RACKLIFE predicted areal density and absorbed dose for each panel from Table 3-1.

The panel enclosure is formed by thin gage (0.020") stainless steel spot welded to the cell structure. Typically the resistance welds are 7 inches apart. Between welds, the thin gage enclosures can bow-out providing a flow path into and out of the panel enclosure. Some of these flow paths are visible at the bottom of the panels (see Figures 4-1 and 4-2). At the weld locations, the wrapper plates tend to pinch the Boraflex and thus provide an anchor point, causing gaps to form as the Boraflex shrinks.

Panel to panel variation in the enclosure fit can lead to significant variations in dissolution. RACKLIFE uses an average value for the panel cavity exchange rate (i.e.,

escape coefficient, measured in cavity volumes per day) and assumes that it is the same for all panels and therefore calculated boron carbide loss for a panel with average exchange rate. On the average, RACKLIFE projections have been shown to be quite accurate but variations in dissolution due to variations in enclosure fit are not considered.

4.3 Gaps, Cracks, and OtherAnomalies The BADGER test data has been evaluated for local effects including panel dissolution, gaps and crack formation as well as global shrinkage. Summary spreadsheets of the evaluated data are contained in Appendix B.

Boraflex is predisposed to forming gaps due to radiation-induced shrinkage. This shrinkage can be accentuated by the non-uniform nature of the gamma dose absorbed by a Boraflex panel in the spent fuel pool racks. Absorbed dose gradients along the length of a panel will cause differential shrinkage, which leads to shear stresses. This process is enhanced by the tendency of Boraflex to swell and fully harden more rapidly where water from the aqueous pool environment can ingress more rapidly into the panel cavity, such as between welds or where there are manufacturing anomalies that permit increased flow into the panel cavity. The result is shrinkage induced gaps and/or cracks [31 A crack is a lateral anomaly that is smaller than 1/3 inch axially, the lower limit on BADGER's ability to detect gaps. This uncertainty (+/- 1/3") has been determined experimentally. A crack may bisect the panel, like a gap. A crack may also just grow a short distance into a panel from the panel edge, often at some angle other than perpendicular to the edge, which is indicative of local shear stresses. Because a crack is below BADGER's resolution, it is also possible that it is simply a region of local dissolution that does not penetrate the thickness of the panel.

Attachment 1 20 PTN-ENG-SEFJ-10-012 Rev. 0 Page 26 of 129

NET 346-01 In addition to gaps and cracks, other anomalies were observed in the Turkey Point Unit 4 panels. These are small areas of end dissolution, typically along the bottom of a panel. For example, these can clearly be seen along the bottom of panel U37 West in Figure 4-2. These local dissolution anomalies sometimes occur around gaps and cracks where the rate of dissolution is accelerated at the fractured surfaces of the Boraflex panels.

Figure 4-9 shows that dissolution tends to more frequently occur toward the bottom of the panels with dissolution less likely to occur at the top of the panels. Figure 4-10 shows that gaps are more or less uniformly distributed, although the distribution may be slightly skewed to the panel bottom. Figure 4-11 shows that if any 1 inch section of the Region 2 racks were to be examined, the maximum amount of coplanar gap per panel would be less than 0.08 inches in that 1 inch slice.

Figure 4-12 shows the frequency distribution of total dissolution along the Region 2 panels. The panel with the greatest local dissolution (28 inches) is V38 North. Figure 4-13 shows the distribution of the number of gaps per panel and indicates that the most likely number of gaps in the Region 2 Boraflex is two. Figure 4-14 shows the distribution of the maximum individual gap size over all of the gaps in a panel. The largest single gap observed is less than 2.6 inches. Figure 4-15 shows the distribution of cumulative gap size in all of the Region 2 panels tested. The largest cumulative gap observed is 6.32 inches.

5.0 CONCLUSION

S A sample of 69 Boraflex panels from the Turkey Point Unit 4 spent fuel racks have been subjected to non-destructive BADGER testing to determine the condition of the Boraflex neutron absorber material for the tested panels. This testing provides to Florida Power and Light detailed information regarding the in-service performance of the Boraflex panels. The observed degradation includes:

general global thinning of the panels;

minor local dissolution in regions of the panels; and

formation of shrinkage-induced gaps.

Panel R36 North had the lowest measured areal density (including gaps) of 0.0107 *ms B-1 0/cm 2 , which is below the minimum certified areal density of 0.012 gms B-10/cm9, but within the measurement uncertainty. Three additional panels (U35 North, S39 North and C6 South) were also below the minimum certified areal density but well within the measurement uncertainty The majority of panels had numerous gaps; however, most gaps were small in size, with the maximum gap size of 2.57 inches in panel C6 South. The gaps are uniformly distributed axially along the panels with no significant coplanar alignment of gaps among the panels. The average cumulative gap size is 1.71 inches, with the maximum cumulative gap at 6.32 inches in panel T40 West. Some local dissolution has occurred around gaps and also in between tack welds along the cover plates. Local dissolution appears to occur predominantly in the lower third of the panels.

Review of the BADGER measured areal density data in Table 4-1 shows good agreement with the RACKLIFE predictions. The average measured areal density of all panels, conservatively including gaps, is 0.0138 gms B-10/cm 2 . The avera 9e areal density predicted by RACKLIFE for these panels was 0.0114 gms B-10/cm . The RACKLIFE predicted results are conservative relative to the BADGER results.

Appendix C Uncertainty Calculations Attachment 1 PTN-ENG-SEFJ-10-012 Rev. 0 Page 127 of 129

Appendix C Uncertainty Calculations The following uncertainty calculations apply to the results presented in Section 4.0 of this report.

These calculations apply, specifically, to the overall panel areal density reported as a percent deviation from the reference "unirradiated" test panels.

The calculations below reflect the assumption that there are two major sources of uncertainty to be accounted for in the testing process, namely, measurement uncertainty and statistical uncertainty.

Measurement uncertainty, K,represents the empirically determined repeatability resulting from scanning a panel from both sides. The fractional measurement uncertainty yields a value between the statistical sample standard error which, for two samples, under-predicts the uncertainty and the population standard error , which, at a 95% confidence level, yields an

(ýN) uncertainty too large to be practical.

Statistical uncertainty, a, propagates the uncertainties associated with the areal density calculations to the total uncertainty. These uncertainties include, but are not limited to: variance of individual panel data points, uncertainty in the unirradiated panel areal density values, goodness of fit for the calibration data regression, and poisson statistics associated with the neutron counts during the testing process. The goodness of fit values -associated with the calibration regression is 96.0%.

The total uncertainty, 6, is the sum of the measurement uncertainty and the statistical uncertainty.

These values are not added in quadrature because they are not known to be independent.

The equations and definitions for i, a, and 6 are depicted below.

The uncertainty in the % deviation (%p) from the unirradiated panels is derived from the total areal density uncertainty. The methods used produce results identical to the standard error propagation method. i.e.:
