1. INTRODUCTION 1.1 Objective Determine the spent fuel isotopic composition for the eighteen VSC-24 MSBs currently loaded at the Palisades nuclear plant, making use of the known, as-loaded fuel data supplied by the customer (as described in Section 4.1). Include all nuclides to be used in the burnup credit criticality analyses to be performed for these MSBs. The output, or results, of this calculation are in the form of SAS2H computer output files that contain axial location-dependent isotopic concentrations for each fuel assembly contained in the MSBs. Concentrations are to be determined in terms of grams of a given nuclide per metric ton of initial uranium.

1.2 Purpose The purpose of this calculation package is to provide the spent fuel isotopic compositions for the burnup-credit criticality analyses to be performed on the eighteen existing VSC-24 MSBs located at the Palisades nuclear plant.

1.3 Scope This calculation applies to the eighteen VSC-24 casks currently loaded and situated on the Palisades ISFSI.

4. ASSUMPTIONS 4.1 Design Configuration Although the work described in this calculation all pertains to loaded VSC-24 MSBs, there are no specific attributes of that design configuration that need be considered in this present calculation, since the MSB configuration does not itself affect the spent fuel isotopic compositions. The configuration details for the fuel assemblies themselves are provided in the customer-provided input data (References 3.2.1 through 3.2.5). Various aspects of the fuel configuration are discussed subsequently in this calculation package.

There are eighteen VSC-24 casks currently loaded and situated on the Palisades ISFSI. These casks are numbered 1-19, excluding 14, which was never placed into service. The casks are numbered as shown in Table 4-1.

In some cases (as in the SASIGEN code input files) the reader may encounter the term cask used to refer to an MSB.

4.1.1 Data for Fuel Assembly and Insert Types Fuel design data, in the form of configurations and dimensions was supplied in Reference 3.2.3. This data is presented in Table 4-2, in terms and units consistent with the inputs to the SASIGEN (and Calc Package No.: VSC-03.3605 Page 15 of 135 Revision 0

SAS2H) computer code. For example, since SASIGEN and SAS2H accept inputs for fuel dimensions on an inner and outer diameter basis and in units of cm, Table 4-2 also expresses these values in these terms. Items to be modeled in the SAS2H path-B model are input in terms of radial dimensions, so these are presented in the table. Dimensions are provided for the 10 fuel assembly types, generally corresponding to 10 differently-lettered batches. In several cases, such as with regions I, J, and K, a particular lettered batch is broken into multiple fuel types; this practice will be clear in referring to the table. Several characteristics do not change from type to type, and these have been omitted from the table. These include an array dimension of 15x15, a single, central, instrument tube, and a guide tube material (where present) of Zircaloy 4. Where guide tubes are present, there are eight per assembly, and the associated guide tube dimensions are provided; in all other cases, no guide tubes are present.

Although in many cases the assemblies include multiple pin enrichments, a given assembly is modeled as having a single average enrichment due to the limitations of the SAS2H control module. None of the rods exhibit an axially-varying enrichment.

For the Type E assembly, the dimensions of the neutron absorber rods are assumed to be the same as those of a standard fuel rod (the only difference being that B4C absorber material is present in place of fuel). All of the above inserts are present during the entire assembly irradiation period, except for the Type 4 (hafnium) inserts, which are only present during the last two cycles of (I1h) assembly irradiation.

Reactor cycle data was provided in Reference 3.2.3 and is presented in Table 4-4. This table is presented in terms of the cycle number for each identified plant operating cycle. In several cases, an historic cycle is broken into two sub-cycles. This is done to account for mid-cycle outages, orin the case of cycle 2a change in core rated thermal power. The table shows the start and end date of each cycle, the core rated thermal power in megawatts, the average boron concentration in parts per million, and the core inlet and core outlet temperature in degrees Fahrenheit.

Control blades, when present, are cruciform and located outboard the assembly. Control blades are further discussed in Sections 4.1.1.5 and 6.7.2.

3 SAS2H represents the boron concentration as decreasing linearly throughout a modeled cycle from 1.9 to 0.1 times the input average concentration. This is described in Reference 3.2.6.

Calc Package No.: VSC-03.3605 Page 20 of 135 Revision 0

4.1.1.1 Fuel Assembly Guide Bars Due to their somewhat irregular geometry, the guide tubes are characterized by an effective radius as shown in Table 4-5, taken from Reference 3.2.4. The use of these effective radius values preserves the quantity of zircaloy material in an assembly.

Table 4-5 Guide Bar Effective Radii Fuel Assembly Batch Effective Radius, cm Types 1 and 2 (A and EF4) 0.5953 Types 3-10 (E - L) 0.5776 4.1.1.2 Description of Fuel Sub-Types and Inserts All features other than the control blades are shown pictorially in Figure 1 through Figure 21 (Control blades are discussed in Section 4.1.1.5). These figures include not only all of the fuel types as described in Table 4-2, but also a range of sub-types. Although all fuel of a particular type has the same general dimensions shown in Table 4-2, these sub-types further distinguish between the various types of inserts used in a particular assembly. The array layouts shown in Figure 1 through Figure 21 are taken from Reference 3.2.1. The configurations shown in Figure 1 through Figure 21 are combined with the fuel assembly and insert data shown in Table 4-1 and Table 4-2 to produce a complete description of the 22 assembly configurations for which SAS2H models are constructed. These configurations are described in Table 4-6, and the sub-types are described at length in Section 6.3.

Gd2O3 absorber rods are identical to fuel rods, other than the presence of Gd2O3 absorber material in the UO2 fuel. The concentration of Gd2O3 absorber included in the fuel material for each sub-type are presented in Table 4-6. The geometries and material compositions of B4C/Al2O3 absorber rods are given in Table 4-3 and in Section 4.1.1.3, respectively.

4.1.1.3 Non-Fuel Material Descriptions The fuel rod cladding, guide tubes, guide bars, and poison rod cladding are all made of Zircaloy-4, as shown in References 3.2.2 and 3.2.3. As shown in Reference 3.2.2, the absorber material in the B4C poison rods consists of an Al2O3 inert material with three different B4C poison material concentrations (1.7%, 4.7%, and 7.7%), as shown in Table 4-6. Pure Al2O3 is loaded in sections of the poison rod that lie within the assembly active fuel zone, but above or below the axial bounds of the poison material; 4 EF is also referred to as D in some of the reference data.

Calc Package No.: VSC-03.3605 Page 21 of 135 Revision 0

this material is conservatively modeled as the poison material in each axial region. Finally, the I1h assemblies described in Table 4-6 contain poison rods with pure hafnium absorber material.

The elemental compositions of all the component materials above are listed in Table 4-7. The composition for Zircaloy-4 is taken from Reference 3.2.10. This is the Zircaloy-4 cladding material composition that was modeled in the (Reference 3.1.2) burned-fuel benchmark analyses that the applied MCNP code bias factors are based upon. Modeling this same cladding material composition provides consistency between and these licensing-basis fuel depletion and criticality analyses and the associated code bias calculations.

The overall B4C concentration for the three types of B4C/Al2O3 poison rod are also shown in Table 4-6 (and taken from Reference 3.2.2). B4C and Al2O3 are shown as compounds in Table 4-7, and are not broken down into component elemental densities. This is because, unlike all the other model component materials, their elemental breakdown is not taken directly from any reference, but instead must be calculated. These elemental compositions for B4C and Al2O3 are presented in Table 6-1 and discussed in Section 6.2.2. The overall B4C/Al2O3 material densities shown in Table 4-7 are taken from Reference 3.2.2. The I1h assembly hafnium absorber rods contain pure hafnium absorber material, over the axial bounds specified in Table 4-6. The density of the hafnium material is taken from Reference 3.2.3.

The specific fuel types with guide tubes surrounding the B4C inserts-and those without guide tubes-are identified specifically in Section 4.1.1.3.1 and 5 Although the actual assembly contains four Gd2O3 rods, six are conservatively modeled to preserve symmetry and to avoid a possible dilution effect of modeling only four. (See 1 All data is taken from Reference 3.2.3, except for the B4C and Gd2O3 concentrations, which are taken from Reference 3.2.2, and the A1 assembly poison rod axial span data, which is taken from Reference 3.2.4.

4.1.1.4 Palisades Plant Notes on Specific Nomenclature and Fuel Types In several assemblies, cert eel dummy rods. The naming system for these assembly types is as follows:

1. H1 becomes H1S, following reconstitution.

2. L1 becomes L1S

3. L2 becomes L2S, etc.

The fuel type designations on the Palisades Fuel Design Data Sheet (References 3.2.1 and 3.2.3) are not used consistently, for example, in the fuel assembly detail figures. There are two key types for which multiple names are used.

1. The fuel referred to on the Data Sheet as type F is referred to in the figures as type XF. These are equivalent.

2. The fuel referred to on the Data Sheet as type EF is referred to in the figures as type D1. These are also equivalent.

4.1.1.5 Information on Control Blades As stated in Reference 3.2.5, the Palisades control blades are composed of Silver/Indium/Cadmium in the following weight percentages80% Ag, 15% In, and 5% Cd. The blades have a cruciform cross-section, 12.250 inches across. The Poison material is 0.176 inches wide, clad with 0.020 304 SS, i.e.,

the total thickness is 0.21620. The bottom 0.984 length is 304L SS, with the bottom 0.5 tapering to a 0.03 radius tip.

Based on References 3.2.2 and 3.2.5, these control blades are inserted to a significant degree only during Cycles 1A, 1B, and 2A, and then only those included in Group 4 are insertedwith the other groups remaining fully withdrawn. When partially inserted, these control blades range from 120 to 130 withdrawn. Table 4-9 presents the assemblies that were located adjacent to Group 4 control blades during Cycles 1A, 1B, and 2A; this information was taken from Reference 3.2.5.

ain fuel rods are ultimately replaced with stainless st 20 Reference 3.2.5 describes the poison material as being 0.176 inches wide, clad with 0.020 304 SS (0.180 total). The parenthetical comment is assumed to be a typo, since the numbers are inconsistent. Furthermore, a clad thickness of 0.002, which would square with the math, is not a plausible mechanical design. The parenthetical comment appears to have been included simply to clarify that the clad thickness needed to be doubled to represent the material across the full blade thickness.

a. Since the clad-to-moderator T is known to be a small but non-negligible component of the total fuel-to-moderator T, it is reasonable to assume that the actual value will fall in a range of 10%-25%.

b. The values in the SCALE validation reports (ORNL/TM-12667, etc.) imply a cladfrac value of ~16.5%, at least in the case of the Calvert Cliffs models.

c. The clad is geometrically small (as a fraction of total fuel material) and is constructed of a material specifically selected for its small nuclear cross-sections. As a result, the selection of the cladfrac parameter over this range is unlikely to have a significant effect on the final spent fuel isotopic compositions.

2. All assembly cooling times are determined based on a single MSB shipment date. Based on discussions with the Owners Group, a date of 1/1/2015

3. Palisades uses cruciform control blades. Based on References 3.2.2 and 3.2.5, these contro blades are inserted to a significant degree only during cycles 1A, 2A, and 1B, and then o those included in Group 4 are insertedwith the other groups remaining fully withdrawn.

When partially inserted, these control blades range from 120 to 130 withdrawn. Even w inserted, the control blades fall fully within the upper two axial zones, which represent the upper 1/9 (11.1%) of a given assembly. The SAS2H models conservatively model the control blade over the full length of the top two assembly zones.

7. The stainless steel plugging rods that replace fuel rods in rods doped with 1% Gd2 asymmetrically, with the the assembly (this is portrayed in Figure 7). These are modeled by modeling 15 features. Each feature is intended to represent the weighted combination of the following features: 8 guide tubes, 1 instrument tube (treated as a guide tube), and 6 Gd2O3 rods. This is discussed further i Section 6.2.4.

The Palisades data indicates one type of insert referred to as Plugging (Insert Type 1). As these are stainless steel and extend only a small distance below the top of the assembly (~1 inch), they are not modeled. The small effect these inserts would have had on a portion of the uppermost axial zone of the assemblies will have a still-smaller effect on the overall criticality of the system.

As the SCALE SAS2H module does not analyze individual rod effects, pin-by-pin variations in burnup and other parameters like temperature, etc., are not modeled. Assembly-average values ins ead used for all input parameters, and all isotopic concentration results thus represent verage values.

ameters such as assembly

, ar calculated on a cycle-average basis. Variations in such parameters within a given cycle are not modeled. This assumption is appropriate as it is cons tor istent with the S2H modeling performed in the SAS2H benchmark evaluation (Reference 3.1.1); the are thus consistent with the SAS2H code bias included in the criticality evaluation.

alyses make use of the bounding 18-zone axial burnup profiles from Reference 3.2.8 ed that the resulting axially-varying isotopic compo is assum sitions are bounding (i.e., more reactive) for any given whole MSB.

13. The initial (fresh fuel) concentrations of 234U and 236U are assumed to be 0.0089 and 0.0046%

of the 235U concentration, respectively. This is consistent with the approach taken in the Reference 3.1.1 SAS2H benchmark analyses.

For Gd2O3 rods, where it is necessary to enter fuel temperatures manually (as opposed to being calculated by the SASIGEN code), a representative temperature of 750 K is assumed.

For the determination of moderator densities for a given local moderator temperature, a reactor pressure of 2250 psi is assumed.

16. The axial moderator temperature profile is calculated based on a cosine power shape, as discussed in Section 5.3.5.

For cases where the Gd2O3 rod UO2 density is not provided in 3.2.2, the density of the UO2 in the Gd O rods is assumed to equal that calculated for the standard 2

The linear, SAS2H-default boron letdown function is assumed in all cases. During each reactor cycle, the soluble boron concentration in the reactor coolant decreases linearly from 1.9 times the cycle-average value (shown in Table 4-4) to 0.1 times the cycle-average value.

5. CALCULATION METHODOLOGY The fuel depletion calculations are performed using the SAS2H control module (Reference 3.2.6) of e SCALE 4.4 code package (Reference 3.2.12). All input files are constructed by means of the SASIGEN Code (Reference 3.2.18), although in several cases the SAS2H input files are subsequently edited. These subsequent editing operations are described in Section 6.7.

This section includes three main subsections. The first section discusses the general SAS2H methodology. The second section presents the general philosophies for path-B model treatments used in modeling the various types of fuel assemblies. Finally, the third section discusses the use of the SASIGEN code for the generation of the large number of SAS2H cases needed for modeling the contents of the 18 MSBs.

5.1 General SAS2H Methodology The isotopic concentrations for each axial zone of each loaded assembly are calculated using the SAS2H module of the SCALE-4.4 code package (Reference 3.2.6), using the same methodologies and modeling assumptions that are used in the SAS2H analyses presented in the benchmark reference documents (References 3.2.12 through 3.2.16). Many of these modeling assumptions are discussed in Section 4. The calculations are performed using the 44GROUPNDF5 cross-section library. Various details of the SAS2H analysis methodology are discussed in the sub-sections below.

5.1.1 Cross-Section Updates In the SAS2H input, the user defines one or more irradiation periods, or cycles. The average thermal power (in MW/MTU) for the period, along with the length of the period, and the lengths of any downtime (zero power) periods between the defined irradiation periods are listed in a single line of input that defines each cycle.

When SAS2H models fuel irradiation, it determines a neutron spectrum at the beginning of the cycle, which is calculated based upon the fuel composition present at the beginning of the cycle. SAS2H then applies a neutron flux, with the initial calculated spectrum, irradiates the fuel with that neutron flux, and determines the number of fissions and the creation of various isotopes. All of these calculations, during the irradiation period, are performed based on the initial neutron spectrum. Since the isotopic concentration itself affects the neutron spectrum, irradiating fuel for too long a period (or more specifically, for too much incremental burnup) leads to inaccuracy in the calculated isotopic concentrations, because the neutron spectrum is no longer valid for the latter parts of the irradiation period (as changes in the isotopic concentrations, and their effects on the neutron spectrum, are not accounted for).

For the above reason, SAS2H needs to periodically update its weighted cross-section set (and neutron energy spectrum) during the irradiation period, based on the changing fuel composition. SAS2H automatically updates the cross-section library at the end of each defined irradiation period, which is usually defined as one full reactor cycle. However, a full reactor cycle may be too long an irradiation period to yield accurate isotopic concentration results, without performing additional, mid-cycle cross-th Calc Package No.: VSC-03.3605 Page 54 of 135 Revision 0

section library updates. There is a SAS2H input command nlib/cyc, which instructs the SAS2H code perform within each defined cycle. If this value is set to 1, no mid-cycle updates are performed. If it is set to 2, a single update is performed halfway through d must be defined between these irradiation periods, with a negligible duration.

one efore a cross-section update is required. Conversely, if the thermal power (burnup rate) is extremely high, cross-section updates will be required sooner. After performing coping evaluations, a maximum allowable burnup increment of ~5 GWd/MTU (to the nearest GWd) ated isotopic concentrations did not change te frequency was increased beyond this point (i.e., were required d in e neutronics of concentration calculation. The neutron spectrum of nuclides within the spent fuel material. All other nuclides are simply neutron flux/spectrum calculations). Otherwise, it is not. While the to-r mark on how many cross-section updates it should the exposure period, etc Note that the same number of mid-cycle updates are performed for each defined cycle, even if the length (or burnup increment) of the defined cycles varies widely. If one wishes to perform multiple cross-section updates in one cycle, but not in others, the only option is to break the cycle in question up into multiple defined irradiation periods. A down perio As isotope concentrations primarily vary with burnup, as opposed to the length of irradiation, BFS decided to establish a maximum burnup increment criterion for cross-section update frequency, as opposed to irradiation period duration. Clearly, if the thermal power (or burnup rate) is very low, can go for a longer period b s

was selected. Scoping studies showed that calcul significantly as the cross-section upda for burnup increments smaller than ~5 GWd/MTU). Thus, in all of the SAS2H analyses performe support of this benchmark evaluation, the cross-section libraries are always updated after burnup increments ~5 GWd/MTU or less. This is consistent with the approach taken in Reference 3.1.1.

5.1.2 Tracked Nuclides As discussed above in Section 5.1, the isotope concentrations themselves can affect th the system, which in turn affects the isotope calculations model a finite set built up (or destroyed) based on the resulting neutron flux and spectrum. The finite set of tracked nuclides basically includes all nuclides that measurably affect the neutron spectrum. All of the significant actinide (e.g., uranium and plutonium) nuclides are automatically tracked by the code.

For fission products, if a given nuclide appears as part of the initial fuel material description, it is tracked (i.e., included in the be-tracked isotopes are included in the initial fuel material description card, their densities are set to 1.0 x 10-20 (to reflect the fact that their actual density is, in fact, zero at the start of fuel irradiation).

A set of 40 fission product isotopes are selected for tracking in these evaluations. In the (example)

SAS2H inputs shown in all of the benchmark reports (References 3.2.12 through 3.2.16) a very simila set of fission product nuclides are listed in the fuel material card. The set of 40 isotopes selected by BFS includes all isotopes tracked by one or more of the SAS2H analyses presented in the bench reports. The set of isotopes selected for tracking in these evaluations are presented in Table 5-1.

As is done in Reference 3.2.8, the d into 18 equal-height zones, each having its own (average) local burnup r,

conservative (bounding) me assembly fuel zone is divide level. Reference 3.2.8 surveyed 3169 individual assembly burnup profiles, based on five different PWR assembly types and 105 different operating cycles. On the basis of this survey, three bounding (i.e., most reactive) axial burnup profiles, recommended for use in burnup-credit criticality evaluations were determined. As discussed in Reference 3.2.8, modeling these very conservative profiles for all assemblies in a large canister (such as the 24-assembly MSB) will be bounding for any actual caniste despite the very rare possibility of a loaded assembly with a non-bounding (outlying) profile, due to the conservatism in the profiles modeled for all the remaining (23) assemblies in the canister.

The profiles vary with assembly-average burnup level, with three profiles defined for three burnup ranges (as described in Section 5.3.5). These three bounding profiles are presented in Table 5-2. The profile presented in Table 5-2 are normalized axial burnup profiles. The local burnup level for each axial zone is determined by multiplying the assembly-average burnup level by the factor shown for that axial assembly zone in Table 5-2.

For every individual assembly loaded into the 18 Palisades MSBs, the average burnup level is determined (from the individual assembly data given in Reference 3.2.3, and in Attachment B of this Tracking refers to placing the selected fission isotopes into the SAS2H initial UO2 fuel description, at negligible sity. SAS2H accounts for the effects of such isotopes when determining the spatially dependent neutron energy spectrum and flux, while performing its weighted cross-section calculations. SAS2H also performs cross-section updates for these isotopes. This is automatically done for all significant actinide isotopes. The selected fission product isotopes are the all the ones that have a significant effect on LWR assembly neutronics.

Based on this data, the irradiation period lengths and down period lengths can be determined for each individual loaded assembly. This cludes the final down period length, or cooling time for the assembly. These period lengths are entered into each corresponding SAS2H input file. This final cooling time parameter is determined based on an assumed MSB shipping date of January 1, 2015, as discussed in Section 4.3.

As discussed in Section 5.3, the calculations discussed above are performed automatically using the SASIGEN code for each individual loaded assembly, using the individual-assembly data given in Attachment B, and the general data presented in Table 4-4 and Table 4-6.

5.1.5 Cycle-Specific Parameter Determination The SAS2H code requires as input a thermal power for each defined irradiation period (or cycle), as well as the temperatures and densities of all materials (which may themselves be fixed or be cycle-dependent).

ture, as discussed in Section 4.3.

The (average) fuel material thermal power levels, in MW/MTU, are determined for each cycle by dividing the increase in burnup that occurs over that cycle (in MWd/MTU) by the duration of the cycle (in days). The beginning and end burnup levels for each cycle (i.e., assembly irradiation period), along with the start and end dates for those cycles, are provided for each loaded assembly in Referen and in Attachment B power levels are determined for each assembly, they are multiplied by the Table 5-2 axial profile factors to yield local fuel thermal power levels for each axial zone of each assembly, as discussed above in Section 5.1.3. The resulting local, cycle-average thermal power level is used in the individ SAS2H analysis that applies for the corresponding axial zone of corresponding assembly. This process is repeated for every cycle (or assembly irradiation period) that applies for the given assembly.

After the thermal power levels are determined for each assembly step in this process is to determine the water temperature for each axial zone. The water temperatures at the bottom and top of the assembly fuel zone are simply equal to the reactor inlet and outlet temperatures shown for each reactor cycle in Table 4-4. The temperatures for the intermediate elevations are determined by assuming a cosine distribution for the axial distribution of assembly thermal power, as is recommended in Reference 3.2.12. Thus, the energy deposited into the water and thus the increase in water temperature with axial elevationis assumed to be proportional average power level times a cosine function, where the power input is maximum at the axial center of the fuel and approaches zero at both ends. Using this approach, an axially-dependent water temperatur profile is determined, along with the resulting average water temperature for each of the 18 defined axial zones (for the cycle in question). This axial water temperature profile is discussed in more detail in Section 5.3.5.

After the water temperature is determined for each axial zone and each cycle, the water density determined based upon an assumed reactor pressure of 2250 psi, interpolating from the density-versus-temperature data given in Table S2.5.2 of Reference 3.2.6.

After the water temperature is determined for each assembly zone and each cycle, the corresponding fuel temperature is determined. Figure 9 of Reference 3.2.12 presents the effective (average) fuel temperature as a function of linear thermal power of the fuel rod (in W/cm). The figure sh o

temperature. The plot shows a temperature of ~675 oC at a rod axial thermal power of 250 W/cm.

Thus, it is assumed that the local fuel temperature (for each axial zone) is equal to the local water temperature plus 375 oC times the local rod axial thermal power in W/cm.

After the cycle-average material temperatures (and water density) are determined, they are entered int the SAS2H input files through the initial material description o

The boron concentration for the first assembly irradiation cycle is defined by the (borated) water material composition description. A bfrac command is used to adjust the boron concentration for subsequent irradiation cycles.

As discussed in Section 4.3, the analyses assume the SAS2H-default boron concentration letdown function, where the boron concentration drops linearly from 1.9 times the cycle-average value (at cycle start) to 0.1 times the cycle-average value (at cycle end). If the number of cross-section upda per cycle exceeds one (i.e., if the nlib/cyc parameter is greater than 1), then SAS2H will automatically calculate an average boron concentration for each resulting sub-cycle, based upon this assumed letdown function.

The second table in Attachment B of this calculation shows which reactor cycles correspond to each irradiation cycle for each individual assembly. This information is necessary to use the Table 4-4 data correctly in determining the cycle-average temperature, density, and boron concentration values for each individual assembly.

Performing the calculations discussed above for every cycle and for every axial zone of every load assembly in each MSB would be very cumbersome due to the very large number of cases involved. F this reason, the SASIGEN code was developed to create SAS2H input files using an automated proces (which requires a much smaller quantity of user input data). The details of how the SASIGEN code performs the calculations and functions above is given in Section 5.3.

5.1.6 Modeled Light Elements In general, various light elem material) are specified in SAS2H fuel depletion analyses, despite the fact that these light elements little or no effect on the calculated spent fuel isotopic concentrations. A generic set of light element masses are assumed for all of these SAS2H fuel depletion analyses. These masses are presented in Table 5-3. This is the same typical set of light element m Calvert Cliffs and H.B. Robinson SAS2H benchmark cases in Table 17 of Reference 3.2.12. These same light element masses were modeled in the corresponding SAS2H benchmark (code bias) ana presented in Reference 3.1.1. Although these light elements are not expected to have any measur impact on the SAS2H spent fuel composition results, they are modeled to maximize consisten the benchmark analyses upon which the determined SAS2H code bias is based.

here are often multiple occurrences of these array features within the entire assembly (such as the ent tube present in the Fuel Type G1 assembly array, as shown in SAS2H performs two sets of neutronics calculations to determine neutron spectrum and weighted average cross-sections. The first calculation is based on an infinite array of fuel rods, based on the fuel pellet O.D., cladding I.D., cladding O.D., and rod pitch that apply for the assembly in question. Then a second calculation is performed to account for significant features in the fuel rod array (such as wate filled guide tubes or neutron absorber rods) that significantly perturb (or affect) the overall assembly neutronics. SAS2H is a 1-D code, which performs its neutronic calculations using an infinite-height concentric cylinder model geometry. Thus, the available mechanism for modeling these assembly array features is to place them at the center of this second (path-B) model and smear the fuel rods around the feature into an effective, homogenous material containing water, cladding, and fuel. This mixture, however, is more than just a mixture of water, clad, and fuel, in that weighted cross-sections for the three main constituent materials (calculated with the initial infinite fuel rod array In T

Figure 5). The path-B model does not consist of the analyzed array feature surrounded by all of the ssemblys fuel rods, as this would be the equivalent of having only one such feature (e.g., guide tube) tire array. Instead a number of fuel rods equal to the total number of assembly fuel rods ivided by the number of features (of the type that is modeled) is modeled around the feature at the center of ed) guide/inst homogenous mixture (material 500) representing 23.11 (208/9) fuel rods would be placed around it.

This more accurately represents the c roxi uel rods to the nearest guide tube (or other features) in the assembly array, and thus more acc ly estimates the neutronic characteristics within the array.

The path-B model consists of a set of concentric cyclinders, each with a given inner and outer radius, and completely filled with a given material (i.e., water, aterial such as Zircaloy, neutron absorber material, or material 500). Note that material 500 only occurs in one of the annular zones.

At the center of the model is the analyzed assembly feature itself, such as a water-filled guide tube, or a neutron absorber rod. For the inner path-B model zones that describe the array feature itself, the zone radii are simple to determine, as they sim lect the radial dimensions of the array feature itself (such as the inner and outer radius of a guide tube). These radii can be directly obtained from the users physical description of the array feature (e.g., the physical description of an annular neutron absorber rod, etc). This simplicity is due to the fact that exactly one array feature is modeled, and the fact that these features are already cylindrical in shape (generally). Outside the inner part of the path-B model at reflects the analyzed array feature itself, things are more complex since square geometry features ust be made cylindrical (through the use of effective radii) and multiple/fractional numbers of xternal features (such as fuel rods) are being modeled.

es that describe the analyzed array feature itself is the array unit cell that surrounds the nit assembly, divided by the number of array features (of the type being analyzed) in the assembly. In the Type G1 assembly example, the area of the annulus would be 23.11 times the square of the rod pitch.

To determine the outer radius of the material 500 zone, a cylinder with an area equal to that of one array unit cell plus the number of fuel rod unit cells in the material 500 annulus is considered. This is because the cylinder in question would include the central unit cell (containing the analyzed feature) a in the en d

the path-B model. For example, for a G1 assembly with 208 fuel rods and 9 (water-fill rument tubes, a guide tube would be placed at the center of the path-B model, and a ollective p mity of the f urate guide tube m ply ref th m

e The first path-B model zone outside the zon water annulus that represents the remaining water in the (square) feature. The area of the array unit cell is the square of the rod pitch. The outer radius of the water u cell zone is set so that the resulting cylinder has an area that is equal to that of the square unit cell, i.e.,

equal to the square of the fuel rod pitch. The inner radius of this annular zone has already been determined, as it is simply the outer radius of the modeled array feature (e.g., guide tube, etc). Also note that the area of the annulus will equal the (square) unit-cell area outside the (cylindrical) array feature, because if the area of the cylinder (inside this O.R.) is equal to the full unit cell area, then the area of the annulus (i.e., the area of the cylinder minus the area of the array feature) is clearly equal to the area of the unit-cell water outside the feature (i.e., the area of the unit cell square minus the area of the feature).

For all path-B models, the next annular zone (outside the unit cell water zone) is the material 500 zone that represents the sub-set of fuel rods that are associated with each array feature (e.g., the 23.11 fuel rods discussed in the example above). The area of the annular material 500 zone is set to equal the collective area of all of the unit cells of the associated fuel rods. Thus, the area of the material 500 annulus is equal to the square of the fuel rod pitch, times the number of fuel rods in the Calc Package No.: VSC-03.3605 Page 63 of 135 Revision 0

along with the material 500 annulus. Thus, in the Type G1 assembly example, the cylinder would have an area equal to 24.11 times the square of the rod pitch. Thus, the outer radius of the material 500 zone is given by:

Pert Rod where R500 is the outer radius of the material 500 zone, NRod is the number of fuel rods in the assembly, NPert is the number of features (perturbations) of the type being analyzed in the path-B model that are present in the actual assembly, and P is the fuel rod pitch.

Generally, a water layer is modeled around the outside of the material 500 zone. This layer represents the water that lies between fuel assemblies when they are in the reactor. The outer radius of this layer is such that the area of the resulting cylinder is exactly equal to the square of the reactor assembly effective pitch divided by the number of analyzed features present in the assembly. In some cases, where multiple perturbation features are present, and only one is being modeled, an outer layer like this will represent the collective area of the features that are not being modeled. For example, in a case where neutron absorber rods and water-filled guide tubes are both present, and the absorber rod is being modeled in the center of the path-B model, an external water layer, calculated on the basis of assembly pitch, will represent not only the water between the the assemblies (in the reactor), but it will s

s, these eight guide bars are modeled as a solid, equal area ring around the material 500 represent all of the water in the guide tube unit cells. This is because the presence of the guide tube will reduce the number of fuel rods in the assembly (for each absorber rod) and will thus reduce the outer radius of the material 500 zone. The outer radius of the external water layer, however, will remain the same, as it is purely a function of the assembly pitch. The result is that the thickness of the external water layer will increase, due to the presence of the guide tubes (as opposed to additional fuel rods). The extra water in the outer water layer represents the water in the guide tubes (and their external unit cells). This extra water models the effect of a guide tube near the edge of the assembly section that is associated with each absorber rod.

The Palisades assembly path-B models differ somewhat from those of typical PWR assemblies, however, due to the presence of eight solid Zicaloy guide bars around the perimeter of the assembly. In these analyse zone. The area of this ring is equal to that of the eight guide bars, divided by the number of modeled features. A ring of water, whose area corresponds to that of the water between assemblies, plus any guide/instrument tube array cells not modeled as the central feature, lies outside this solid Zircaloy ring. This is described further in Sections 5.3.5 and 6.2.1.

The path-B model zones described above (and the methods for determining their radii), cover all of the zones generally present in most path-B models. In the relatively rare case of the partially-inserted control blades, a somewhat more involved path-B model is constructed. The development of this model is described in Section 5.4.1.

Calc Package No.: VSC-03.3605 Page 64 of 135 Revision 0

Some cases involve complications that can not be rigorously treated by the SAS2H path-B model. In these cases, approximations must be made. In the case of Assembly Type G3 (Figure 7), for exampl there are 8 guide tubes, in e,

strument tube, and 6 burnable poison rods to be modeledfor a total of 15 potential features. As discussed in Section 6.2.4, the SAS2H analyses treat this by modeling 15 atures containing neutron absorber rods with the area of the rod zones (absorber and cladding) reduced to 6/15 of their nominal value. The radii of the inner zones of the path-B model are reduced accordingly. The guide tube zone radii are not adjusted, and the remaining zones of the path-B model re calculated normally, using the methods discussed above. With this approach, a sort of average ature (6/15 absorber rod, 9/15 pure water) is modeled at the center of the path-B model. This general for model to be changed for peats fe a

fe treatment is consistent with the approach employed in References 3.2.12 and 3.1.1.

Also, as discussed in Section 4.1, sometimes significant array perturbation features are only present part of the assemblys irradiation history. SAS2H does allow for the path-B different defined irradiation periods, but it is cumbersome. There are two options. If the mxre card is left out, or set to a value other than zero, then a single line of input describing the path-B model is entered, and this description is assumed to apply for all cycles. The other option is setting mxrepeats to zero, and entering a separate path-B model card (or line), not only for every defined reactor cycle, but for every cross-section update period. Thus, the total number of lines equals the number of cycles times the value of the nlib/cyc parameter. Thus, the number of lines can get quite large, but this is necessary if any changes in the path-B model are to be analyzed. Generally, all of the zones (and radii) necessary to describe the array feature (such as an absorber rod) are entered in a path-B model line, and this line is copied as many times as necessary. For the sub-cycles when the absorber rods are absent, the absorber rod materials (absorber, clad, etc) are simply all changed to water.

Additional details of the construction of the Palisades assembly path-B models are discussed in 5.3.

Calc Package No.: VSC-03.3605 Page 65 of 135 Revision 0

5.2.1 SAS2H Path-B Model Selection As discussed above, in several cases there are multiple features that could be modeled. Several different approaches to modeling these features were considered:

1. Model both types of features

2. Model each feature and take the worst result

3. Move one of the features to the outside of the path-B model.

The approach taken was decided on a case-by-case basis, considering the significance, number, and placement of the feature. One such example is the G3 assembly, discussed in Section 6.2.4.

5.3 Use of the SASIGEN Computer Code All runs are prepared by means of the SASIGEN Code (Reference 3.2.18), a BFS Category 2, internally developed computer program. This is done for two reasons. First, the present characterization of the spent fuel in the loaded Palisades MSBs requires the use of 7776 SAS2H runs s

ould be extremely time-consuming and potentially error-prone. Second, in order to allow for the ber of input files, it is beneficial to make use of the BFS software processdoing substantial portion of the methodology-checking during the software validation phase rather than at ance of a large number of analyses.

itations of the SASIGEN code, the SAS2H input files are subsequently edited. This is discussed in Section 5.4.

5.3.1 Description of the SASIGEN Code SASIGEN (SAS Input Generator) is a computer code used to automate the preparation of SCALE SAS2H input files to enable the performance of isotopic buildup and depletion calculations. The user supplies an input file with various fuel parameters (physical and operational) and the code produces the corresponding SAS2H input file. SASIGEN is a BFS Category 2, internally developed computer program. The code runs in a DOS shell on Personal Computers running under various versions of the Windows operating system. Each execution of SASIGEN is intended to model a single loaded MSB, although it is also possible to model a smaller number of assemblies than a fully-loaded MSB.

5.3.2 SASIGEN Code Inputs The input file consists of a title card, a desired decay (or shipping) date, a Tclad fraction (described below). The input file also contains one set of data for each assembly to be modeled.

As discussed A path-B model is included in each SAS2H input file and is based on the general model shown in ptional materials. The two innermost rings can be viewed as optional and can be filled with water to effectively remove them from the model. The rings immediately inside and immediately outside the guide tube ring must be water but are of arbitrary size. The guide tube shown in the figure need not be an actual guide tube and can be composed of any of the materials defined in the given case.

lated from the values provided in Refe in Section 5.1.1, the library update frequency is set to the minimum value required to ensure that there is at least one code subcycle (and hence one library update) for every 5000 MWD/MTU of burnup.

Final decay times are determined based on the end date of the final cycle and the user-specified shipment date.

Due to the use at Palisades of cruc y to develop an effective assembly pitch, which accounts for the narrow gap on two sides of the assembly and the wide gap that falls on the other two sides. From Reference 3.2.2 the wide water gap (i.e., the control blade channel) is 2 x 0.464 cm = 0.928 cm. The same reference also provides the narrow gap, 2 x 0.133 = 0.266 cm. The effective assembly pitch is e

Finally, with regard to the water gap at the outside of the path-B model, the area of this outer ring effectively accounts for two things. First, this outer ring accounts for the areal difference between the rod pitch squared times the total number of pin lattice locations (whethe occupi by fuel rods, poiso rods, guide tubes, or instrument tubes) and the s iform control blades, it is necessar then given by Nrods per row x pitch plus the average of the narrow and wide gap thicknesses Calc Package No.: VSC-03.3605 Page 71 of 135 Revision 0

For a rod pitch of 1.397 cm, the effective assembly pitch is 21.552 cm.

Second, the outer ring accounts for any additional water inside the fuel assembly that is not associated with a particular modeled object occupying a rod pitch location. For example, when the modeled EN feature is a poison rod and there exist additional guide tubes that are not explicitly modeled, SASIG automatically places the water associated with these guide tubes in the outermost ring of the path-B model.

5.4 Subsequ In several cases the SAS2H input files are subsequently edited. In general, this is done when the items being modeled could not be fully automated through SASIGEN. Although the SASIGEN code offers a significant degree of flexibility for modeling various fuel types, insert configurations, and plant operating details, situations remain where it is necessary to make changes to individual SAS2H input files. Details requiring additional hand treatment include situations where inserts vary with axial position or with operating time as well as cases where fuel has been reconfigured during its operating history.

There are three categories of details where such hand edits were required. First, in the case of the hafnium absorbers loaded into I1H assemblies following a number of cycles of operation, the SAS2H input files are subsequently hand-edited in order to produce the required cycle-dependent and library update-dependent path-B lines. Second, in treating the effects of partially-inserted control blades, it is necessary to make use of cycle-varying changes to the input files; again, this requires the use of hand-editing. Third, the G2, H2, I3, and I1H fuel types, as described in Sections 6.3.6, 6.3.9, and 6.3.12 require a hand edit to allow for the modeling of the reduced-density zircaloy used to represent the materials in the combined clad/gap space. The specific effects being treated and the changes made are described in Section 6.7.

5.4.1 Modeling of Partially-Inserted Control Blades The path-B model zones described above (and the methods for determining their radii), cover all of the zones generally present in most path-B models. In a small number of casesthe Palisades assemblies adjacent to partially-inserted control bladesan external feature (the control blade) is present. In this case, the control blade is modeled through the addition of two additional annular zones which are placed just outside the zircaloy ring representing the guide bars. The first of these additional rings has a thickness equivalent to the water channel between the fuel assembly and the control blade. The second ring represents the control blade itself, and is composed homogenously of Ag-In-Cd and 304 SS in the quantity and volume fraction required to conserve the amounts of these control blade materials. Thus, the additional zone has an overall area equal to that of the contributing area of the control blade divided by the number of array features. The contributing area of the control blade is determined by dividing the full cruciform control blade area by the number of assemblies sharing that object. Since four assemblies surround a control blade, one fourth of the full cruciform blades area is considered in constructing a path-B model. Finally, an outer water ring is included with a thickness equivalent to the water channel falling outboard of the control blade. The setup of this path-B model is presented in Figure 24.

The above modeling approach effectively models a half-thickness control blade on all four sides of the assembly, as compared to the physical configuration where the full-thickness blade lies on two sides of the assembly. Such an approach is necessary because SAS2H (and its associated path-B model) requires radial symmetry. The above approach is conservative, however, for the following reasons. The ent Hand-Editing of SAS2H Input Files Calc Package No.: VSC-03.3605 Page 75 of 135 Revision 0

presence of neutron absorber materials generally increases reactivity due to neutron spectral hardening nd the associated increase in plutonium production in the fuel. Moving neutron absorber material from the back half of the blades present on two sides of the assembly, and moving it over to the two e overall effectiveness of the neutron l

a other (unoccupied) sides of the assembly will increase th absorber material. This is especially true given the fact that the control blade is already quite black to neutrons, and the absorber material on the back side of the blade would have had relatively little effect.

The effectiveness, or worth of the absorber material is thus substantially increased by placing it in close contact with the other two sides of the assembly. It should also be noted that, although additiona water is modeled on the far side of the control blade material ring, its presence (or thickness) will have little effect on the neutronics, or on the fuel depletion analysis in general.

6. CALCULATIONS 6.1 SASIGEN Code Generation of SAS2H Path-B Models As discussed in Section 5, a path-B model is defined for each assembly type in the SAS2H analyses.

Row 5 of the SASIGEN input file (as well as the equivalent lines for subsequent assemblies) provides the information to be used in the construction of the path-B model to be included in the SAS2H cases for the first assembly in the MSB. The user-supplied data in this row is shown below; the (1) denotes the first assembly. Path-B inputs for subsequent assemblies are provided in the same format.

assypitch(1) - Assembly-to-assembly pitch for first assembly, cm Ngt(1) - Number of guide tubes per assembly 1 GTir(1) - Inner radius of guide tube in first assembly, cm GTor(1) - Outer radius of guide tube in first assembly, cm Mgt(1) - SAS2H guide tube material number (first assembly)

Mring1(1) - Mixture number of ring 1 in first assembly.

Rring1(1) - Radius of ring 1 for first assembly, if used, cm.

Mring2(1) - Mixture number of ring 2 in first assembly Rring2(1) - Radius of ring 2 in first assembly, cm Mouter(1) - Mixture number of outer ring in first assembly Writemodtemp(1) - Flag indicating whether the moderator temperature is to be included at the end of the material compositions in the SAS2H input files for assembly 1 Mextra(1) - Mixture number of extra ring immediately inside the outer ring in first assembly (Enter 0 if an extra ring is not desired.)

Rextra(1) - Radius of extra ring immediately inside the outer ring in first assembly, cm (Value is not used if Mextra is 0, but must be entered nonetheless.)

All path-B models prepared by the SASIGEN code consist of 8 concentric rings. The positions of the various rings that can be modeled in the Path-B model are shown in Figure 23. If a particular ring is not needed to model a given fuel type, the same mixture number is simply entered for multiple adjacent rings. For example, if there are no features housed inside a guide tube, a 3 is simply entered as the material number for Ring1 and Ring2.

Entering a guide tube radius greater than or equal to GTir(1) will cause the code to override this with a n Gtir(1). This allows a user simply to maintain a large value (e.g., 100.0) to make use of the codes override capability.

Although the three-line version results in a SAS2H input file with a temperature and the word end after each of these lines, a check of the SAS processing makes it clear that the densities are being properly read and interpreted.

As stated in Section 4.1, some of the B4C rods exist in assemblies with no guide tubes. In this case, the B C rods themselves are modeled as the feature in the path-B model. In other cases, the B4C rods are embly. In this case, both the rod and the guide tube are ll, there are three different concentrations of B4C in burnable absorber rods: 1.7, 4.7, and 7.7 t-%.

In such cases, the calculated UO2 density is taken from the SAS2H inputs files generated by SASIGEN - that density is calculated by the code as described in 5.3.5.

Several Palisades assembly types contain UO2 fuel rods that include Gd2O3 absorber material, at the weight percentages shown (for each assembly type) in Table 4-6.

.449 6.2.3 Treatment of Guide Tubes and Instrument Tubes In fuel assemblies where the key path-B features to be modeled are guide tubes (8 tubes) in addition to an instrument tube, the path-B model is constructed to treat the instrument tube, in essence, as a ninth J1.

e sent the weighted combination of the following features: eight guide d2O3 rods. More detail is provided on guide tube. Although the dimensions are slightly different, this treatment is more accurate than simply neglecting the instrument tube, which would result in its being modeled at the outer radius of the path-B model. Assembly types where this approach has been used include G1, H1, H1S, I1, I2, and In addition, assembly types G3 and H3 model the instrument tube in conjunction with more than on feature, as in the Gd2O3/Guide Tube treatment discussed in Section 6.2.4 below.

6.2.4 Treatment of Assemblies Containing both Gd2O3 and Guide Tubes The Palisades G3 fuel assemblies include two features to be studied: eight guide tubes; and four fuel rods doped with 1% Gd2O3. As an additional complexity, the Gd rods are positioned asymmetrically, with the four rods shifted upward, as shown in Figure 7. An equivalent, symmetrical array would contain six rods, which are conservatively modeled. These are modeled as a total of fifteen features.

Each feature is intended to repre tubes, one instrument tube (treated as a guide tube), and six G this modeling in the section discussing the G3 assembly belowSection 6.3.7.

Examination of Table 6-5 shows that this is done for many assembly types, such as assemblies that do not have poison rods inserted into guide tubes, for example, where multiple water zones are defined inside the guide tubes. In such cases, many of the radial dimensions are not relevant, and are therefor chosen arbitrarily. As discussed in Section 6.1, the SASIGEN code automatically sets such radii to be 0.001 cm less than the meaningful radius that lies just outboard.

There a n MSB 16, three in MSB 17, four in SB 18, and three in MSB 19. The I1 models were modified to add hafnium material. Although these el types are constructed, they are not run directly; rather they are used as the basis for the additional lines to be included in the multiple path-B models described below.

This is judged to J2 and K2 are comparable to the I4 model. No physical dimensions are different. J2 and K2 are themselves physically identical.

iii. The model continues to model the replaced pins as fuel.

v. Note that this second portion has a slightly higher enrichment, due to the fact that only lower-enrichment edge and corner rods are replaced with the stainles steel rods.

Unlike the other rods described in this section, these additional rods were not removed from assemblies that are loaded into the eighteen MSBs being analyzed in this calculation package. It is therefore necessary to construct an additional SASIGEN run to produce SAS2H files to analyze the inventory of these rods. Since the runs are again based on a single metric ton of initial uranium, it is immaterial whether the cases model the entire assemblies or merely rods from these assemblies.

The assemblies containing the additional rods are presented in Table 6-7. One of the assemblies, Assembly L02, is of Fuel Type L2 (Figure 18), while the remaining four are of Fuel Type L1 (Figure 16). All five assemblies were loaded in the Palisades reactor during plant cycles 8, 9, and 10. Table 6-7 provides the enrichment, fuel mass, and burnup data for each of the five assemblies.

6.7.3 Hand Edits of Reduced-Density Zircaloy Models As discussed in Section 6.3, several assembly types involve the use of a reduced-density zircaloy material, which is necessitated by the fact that there are not enough rings in SASIGEN to permit the modeling of a gap between the Hf rod and the clad. As an alternative modeling method, the reduced-density zircaloy is modeled in the combined clad/gap space. The development of the Zirc relative density (or volume fraction) is described in Sections 6.3.6, 6.3.9, and 6.3.12 for the affected fuel assembly types: G2, H2, I3, and I1H.

Due to its having a sufficiently complex material definition, the SASIGEN-generated zircaloy material line for material 5 extends onto a second line. Without further editing, the formatting of this line leads to SAS2H run failures (specifically, when the codes writemodtemp feature is invoked, as is the case in these runs). To overcome this difficulty, a hand-edit is performed. The material definition is changed from this format:

arbmzirc 6.56 5 0 0 0 8016 0.12 24000 0.10 26000 0.20 50000 1.40 569.6 end 40000 98.18 5.7407 569.6 end to this:

The following vi edit command sequence was used to delete the extraneous temperature and end label in the SAS2H input files for affected assembly types.

n These editor commands simply find the character string 50000 1.40, move ahead two words, delete the remainder of the line, write the file, and step to the next file in the editor sequence. The SAS2H input files are otherwise unchanged, with the exception of the I1H assemblies, whose additional edits are discussed elsewhere in this document.
