Numerical Applications Inc. Page 7 of 185 Palisades Design Basis Cask Drop Accident AST Radiological Analysis Calculation Number: NAI-1149-026 Rev. 0 1.0 Introduction The purpose of this calculation is to reanalyze the radiological consequences of the Cask Drop Accident (CDA) presented in Section 14.11 of the Palisades FSAR (Reference 2). This reanalysis will use the AST methodology described in Regulatory Guide 1.183 (Reference 1).

Although Appendix B of the Reg. Guide outlines the requirements for performing a radiological analysis of a fuel handling accident, it is assumed that the same guidance would apply to the CDA.

There are two possible release paths for the activity that escapes the fuel pool in the fuel handling building (FHB); an unfiltered release that travels to the containment and exits via the containment equipment hatch, and a filtered release via the FHB ventilation system which exhausts via the plant stack. Three cases were analyzed:

Case 1 with 90% of the release via the FHB filtration system, 30 days of decay, and the control room initially aligned in emergency recirculation mode.

Case 2 with 82.5% of the release via the FHB filtration system, 30 days of decay, and the control room initially aligned in emergency recirculation mode.

Case 3 with 0% of the release via the FHB filtration system, 90 days of decay, and no isolation of the control room.

2.0 Summary of Results The following table presents the results of the CDA cases. The direct shine dose contribution is the sum of the cloud and filter shine doses documented in Table 1 of Reference 12.

Numerical Applications Inc. Page 9 of 185 Palisades Design Basis Cask Drop Accident AST Radiological Analysis Calculation Number: NAI-1149-026 Rev. 0 3.0 Design Input 3.1 Source Term Input Reference 5 defines the event as damage to all of the fuel pins in 73 fuel assemblies. As described in Section 6.3 of Reference 8, the design basis source term for the CDA is defined in Table 6-9 (for 30 days of decay) and Table 6-10 (for 90 days of decay) of that calculation and incorporated into the nif files included as Attachments 26 and 27 to that calculation. Note that per the discussion given in Section 7.1.14, the activities for I-131 and Kr-85 will be adjusted to account for different gap release fractions for these isotopes as specified by Table 3 of Reg.

Guide 1.183. In addition, the CDA source terms are adjusted to represent the activities for 73 fuel assemblies versus the activities for one assembly given in Reference 8.

3.2 Other Input Reference 5 lists other input, provided by Palisades, used in the development of the Palisades CDA RADTRAD-NAI models.

4.0 Assumptions

Mixing of the release from the fuel pool with the fuel handling building atmosphere and containment atmosphere is ignored.

At all times, a minimum of 23.4 feet of water is maintained above the damaged fuel.

Per Reg. Guide 1.183, the release is assumed to occur over a 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months period.

Numerical Applications Inc. Page 10 of 185 Palisades Design Basis Cask Drop Accident AST Radiological Analysis Calculation Number: NAI-1149-026 Rev. 0 5.0 Acceptance Criteria It is assumed that the fuel handling accident dose limits also apply to the CDA. Per Section 4.4 and Table 6 of Reg. Guide 1.183, the acceptable dose limits for the Exclusion Area Boundary (EAB), Low Population Zone (LPZ), and Control Room (CR) for a FHA are:

CDA Dose Limits Area Dose Criteria EAB 6.3 rem (TEDE) (worst 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months )

LPZ 6.3 rem (TEDE) (for 30 days)

Control Room 5 rem (TEDE) (for 30 days)

Control room dose limit is specified in 10CFR50.67 6.0 Computer Codes The following computer code was used for performing the analyses presented in this calculation:

Computer Code Version Reference Purpose RADTRAD-NAI 1.1a(QA) 3 Radiological Dose Calculations RADTRAD-NAI (Reference 3) is qualified and maintained under the Numerical Applications Inc.

QA program (Reference 4). This QA program meets the requirements of 10CFR50 Appendix B with code error reporting per 10CFR21. RADTRAD-NAI is accessed via a controlled access web-based interface that provides a front-end for developing and submitting input models. The input developed via the interface is submitted to the RADTRAD-NAI solver that runs on an AMD-ATHLON based personal computer running LINUX.

Numerical Applications Inc. Page 11 of 185 Palisades Design Basis Cask Drop Accident AST Radiological Analysis Calculation Number: NAI-1149-026 Rev. 0 7.0 Calculations Appendix B to Reg. Guide 1.183 sets the requirements for the transport, reduction, and release of radionuclides for the fuel handling accident. It is assumed that the same requirements apply to the CDA.

7.1 Cask Drop Accident Case 1 RADTRAD-NAI Model The RADTRAD-NAI model developed for the CDA calculation consists of four compartments and six pathways (see Figure 1):

7.1.1 Fuel Pool Release-Unfiltered (Compartment 1)

The following input was specified for the fuel pool source volume connected to the unfiltered release path:

Dummy value assumed, a convective flow path is used to Volume 10,000 ft3 release the fuel pool activity to the environment Source Fraction 0.10 10% of release is via the unfiltered pathway Recirculation Filters no Natural Deposition no Overlying Pool yes Model 23.4 feet of water above damaged fuel assemblies 7.1.2 Environment (Compartment 2)

The only required input for the environment compartment is volume. This value is a dummy value; however, an input is required for this field. An arbitrary value of 2.0E20 ft3 was specified.

7.1.3 Control Room (Compartment 3)

The control room volume was set to 35,923 ft3. The control room HVAC system is assumed to be operating in emergency mode at the beginning of the event.

The following input was specified for the fuel pool source volume connected to the filtered release path:

This pathway connects the Fuel Pool-Unfiltered (Compartment 1) with the Environment Compartment (Compartment 2) and represents the unfiltered release that exits via the containment equipment hatch. Reg. Guide 1.183 specifies that the release from the spent fuel pool be leaked to the environment over a two hour period. The two hour release period is handled via the release fraction timing file; therefore, a high flow rate is used to extract the

Numerical Applications Inc. Page 14 of 185 Palisades Design Basis Cask Drop Accident AST Radiological Analysis Calculation Number: NAI-1149-026 Rev. 0 release from the fuel pool compartment. A 100% filter efficiency is specified for the aerosol release fraction (no aerosol release per page B-2 of Reg. Guide 1.183).

Numerical Applications Inc. Page 15 of 185 Palisades Design Basis Cask Drop Accident AST Radiological Analysis Calculation Number: NAI-1149-026 Rev. 0 7.1.10 Fuel Pool Filtered Release to Environment (Pathway 6)

This pathway connects the Fuel Pool-Filtered Compartment (Compartment 4) with the Environment Compartment (Compartment 2) and represents the filtered release that exits via the FHB filtration system exhausting via the plant stack. Reg. Guide 1.183 specifies that the release from the spent fuel pool be leaked to the environment over a two hour period. The two hour release period is handled via the release fraction timing file; therefore, a high flow rate is used to extract the release from the fuel pool compartment. A 100% filter efficiency is specified for the aerosol release fraction, and a 94% elemental and organic efficiency was specified (References 5 and 14).

The nuclide inventory file contains the total number of curies for one damaged fuel assembly (adjusted to 73 assemblies per Section 0; therefore, the plant power entry in the RADTRAD-NAI input file was also set to 2703 MWth. Item 1.3 of Appendix B to Reg. Guide 1.183 specifies that the makeup of the iodine species is 99.85% elemental and 0.15% organic:

Start of first release time (hours) 0.0 Calculate decay yes Calculate daughters yes Iodine Fraction - aerosol 0.0 Iodine Fraction - elemental 0.9985 Iodine Fraction - organic 0.0015 7.1.12 Overlying Pool Item 2 of Appendix B to Reg. Guide 1.183 states:

If the depth of water above the damaged fuel is 23 feet or greater, the decontamination factors for the elemental and organic species are 500 and 1, respectively, giving an overall effective decontamination factor of 200 (i.e., 99.5% of the total iodine released from the damaged rods is retained by the water). This difference in decontamination factors for elemental (99.85%) and organic iodine (0.15%) species results in the iodine above the water being composed of 57% elemental and 43% organic species. If the depth of water is not 23 feet, the decontamination factor will have to be determined on a case-by-case method (Ref. B-1).

The guidance quoted above sets out an inconsistent set of conditions for the elemental iodine decontamination factor. Recent clarification from the NRC indicates that the appropriate criteria is on overall decontamination factor of 200. Based on the release fractions of 99.85% elemental and 0.15% organic, an elemental iodine decontamination factor of approximately 285 is required to produce an overall decontamination factor of 200.

Numerical Applications Inc. Page 16 of 185 Palisades Design Basis Cask Drop Accident AST Radiological Analysis Calculation Number: NAI-1149-026 Rev. 0 In addition, Section 3.0 of Appendix B to Reg. Guide 1.183 states:

The retention of noble gases in the water in the fuel pool or reactor cavity is negligible (i.e., decontamination factor of 1). Particulate radionuclides are assumed to be retained by the water in the fuel pool or reactor cavity (i.e., infinite decontamination factor).

Per the inputs listed in Reference 5, 23.4 feet of water will be maintained above the damaged fuel; therefore, the decontamination factor for elemental iodine was set to 285. The decontamination factor for organic iodine was set to 1.0.

7.1.13 Dose Location Information Three dose locations were specified; the Exclusion Boundary (EAB), the Low Population Zone (LPZ), and the Control Room (CR). The X/Qs for the EAB and LPZ are from Table 5 of Reference 10. The breathing rates are from Section 4.1.3 of Reg. Guide 1.183:

Guide 1.183 specifies the radionuclide groups that should be considered. Reference 9 provides a listing of the individual nuclides and dose conversion factors used for the analyses presented in this calculation. The data provided in Reference 9 are consistent with Reg. Guide 1.183. The dose conversion factors provided in Reference 9 were obtained from Table 2.1 of Federal Guidance Report 11 and Table III.1 of Federal Guidance Report 12.

Table 3 of Reg. Guide 1.183 specifies the following composition for the non-LOCA fraction of fission product inventory in the fuel rod gap:

Group Fraction I-131 0.08 Kr-85 0.10 Other Noble Gases 0.05 Other Halogens 0.05 Alkali Metals 0.12 The release fractions for iodine and noble gases, were set to 5% in the release fraction timing file.

The release fraction for I-131 is 0.08 versus 0.05 for the remaining iodine isotopes. To account for this difference, the source term for I-131 in the RADTRAD-NAI nuclide inventory (nif) files was increased by a factor of 1.6 (0.08 / 0.05). Similarly, the Kr-85 source was increased by a factor of 2.0 to adjust the Kr-85 release to the specified 10% while retaining other noble gas releases at 5% as prescribed in the release fraction timing file pal_cda_ast.rft (Table 7-1). The Reference 8 activities were further adjusted to represent 73 fuel assemblies. The final adjusted CDA nif files, pal_cask30_db_ast_adjusted.nif and pal_cask90_db_ast_adjusted.nif, are provided in Attachment 5 and Attachment 6.

Release Fraction Timing File presents the release fraction timing file used for the CDA. The 30 day and 90 day decay periods are accounted for in the CDA source term files (nif files).

7.3 Cask Drop Accident Case 3 RADTRAD-NAI Model This model is similar to that documented in Section 7.1. The differences are:

The filtered release was set to 0% and the unfiltered release was set to 100%.

The 90 day decay cask drop source was used.

The control room was set to operate in normal mode for the entire event (660 cfm unfiltered makeup, 0 cfm filtered makeup, 0 cfm unfiltered inleakage, and no control room recirculation flow).

Response: Table numbers corrected to 6-9 and 6-10.

Comment 2 Page 15, Section 7.1.10 - Please include Reference 5 in addition to Reference 14 for the filter efficiencies.

Response: Reference 5 added.

Comment 3 Page 19, Paragraph above Tables 7 There appears to be an error in the link of the Release Fraction Timing File when I printed the page.

Response: Link deleted.

Comment 4 Table 7 The release fraction timing file includes two 0.1E-2 hour delays before the release begins. This 0.002 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months (7.2 seconds) delay should not have a significant impact on the total dose.

Response: Agreed. Minimal time periods are required in the release fraction timing file so that the main release will occur during the third release phase. This is required because the overlying pool model only operates during the third release phase.
