9 APPENDICES A SAMA CANDIDATE MACCS2 RUNS Revision 0 IP-RPT-16-00077, Rev. 0 Page 4 of 36 Page 3 of 35 021059-CALC-13106 Indian Point RAI CLl-16-07 1.0 PURPOSE This calculation documents a series of MACCS2 sensitivity cases that were performed to support the response to an NRC Staff Request for Additional Information (RAI) pertaining to the NRC Commission Decision CLl-16-07 for Indian Point Energy Center (IPEC). On May 4, 2016, the Commission issued a decision (CLl-16-07)

[1] in the Indian Point Nuclear Generating Unit Nos 2 and 3 (IP2 and IP3) license renewal proceeding, in which it directed the NRC staff to supplement the IP2 and IP3 Severe Accident Mitigation Alternatives (SAMA) analysis with additional sensitivity analyses.

Specifically, the Commission held that documentation was lacking for two inputs -decontamination time (TIMDEC) and cost to decontaminate non-farmland (CDNFRM) --used in the MELCOR Accident Consequence Code (MACCS)1 computer analyses, and that uncertainties in those input values could potentially affect the SAMA analysis cost-benefit conclusions.

The Commission therefore directed the NRC staff to perform additional sensitivity analyses.

In a Request for Additional Information (RAI) dated September 12, 2016 [2], the NRC staff requested the following additional information:

1. Entergy Nuclear Operations, Inc. (Entergy) is requested to scale up the value of nonfarm wealth (VALWNF) input to the SAMA analysis' base-year dollars (see pp. 41-42 of CLl-16-07), and to re-run its base analyses using this corrected VALWNF input. Entergy is requested to evaluate how the change in VALWNF may affect its identification of potentially cost-beneficial SAMAs. 2. Using the revised baseline from Request 1, Entergy is requested to run supplemental sensitivity analyses using the input values specified in CLl-16-07.

Specifically:

  • Apply the maximum values specified by the Commission and allowed by the MACCS code for TIMDEC and CDNFRM values (one year (365 days) and $100,000, respectively) for "heavy decontamination" (i.e., the decontamination/dose reduction factor of 15).
  • Exercise the additional option to explain, with sufficient justification, its rationale for choosing any additional values for the TIMDEC and CDNFRM inputs for its sensitivity analyses.

Entergy at a minimum should run its sensitivity analyses for the four worst release categories, as specified in CLl-16-07.

Entergy is requested to evaluate how these sensitivity analyses may affect its identification of potentially cost-beneficial SAMAs. Upon completing these additional analyses, Entergy is requested to submit the input and output files for the IP2 and IP3 MACCS code. Additionally, Entergy is requested to submit the spreadsheet (or equivalent table if another method is used) that conveys the population dose and off-site economic cost for each release category and integrates the results into a Population Dose Risk and an Offsite Economic Cost Risk for IP2 and IP3. 1 The text in this section is largely taken from the NRC RAI. Whereas the RAI text specifies the MACCS code, it is understood that the more current version of the code, typically referred to as MACCS2, is intended.

The MACCS2 code was used in this analysis.

  • All assumptions utilized in Reference 3, the MACCS2 model analysis calculation that serves as the basis for the SAMA, are carried forward to this calculation.

4.0 METHODOLOGY To address this RAI, a series of MACCS2 (version 1.13.1) sensitivity cases are performed with adjustments to select MACCS2 parameter input values. For each sensitivity case, the MACCS2 results for total 50-mile offsite costs and 50-mile population dose for each release category are multiplied by the applicable release category frequency to calculate the SAMA metrics of Offsite Economic Cost Risk (OECR) and Population Dose Risk (PDR). The OECR and PDR of the various sensitivity cases are then compared against applicable reference cases to determine the impact of the revised parameters.

It is noted that more MACCS2 cases are documented than are strictly required to address the RAI response.

These additional cases were performed to gain more refined insights into the sensitivity of OECR anc:t PDR results to select input values. They are documented herein for completeness purposes.

'021059-CALC-13106 Indian Point RAI CLl-16-07 For each IPEC unit, the following sensitivity cases are performed:

  • Case O o SAMA Base Case Check o This case confirms that the results of Reference 3 can be reproduced with the applicable MACCS2 files upon which the sensitivity cases are built.
  • Case 1 o TIMDEC is escalated to one year (365 days) for DF=15 in the CHRONC input file. o This Tl MDEC value represents the maximum value allowed by MACCS2. o This case is not used to support the RAI response.
  • Case 2 o CDNFRM is escalated to $100,000/person for DF=15 in the CHRONC input file. o This CDNFRM value represents the maximum value allowed by MACCS2. o This case is not used to support the RAI response.
  • Case 3 o TIMDEC is escalated to one year (365 days) and CDNFRM was escalated to $100,000/person for DF=15 in the CHRONC input file. o This TIMDEC and CDNFRM values represent the maximum values allowed by MACCS2. o This case is not used to support the RAI response.
  • Case 4 o VALWNF & VNFRM (including lost tourism and business) are escalated to 2005 values. VALWNF is used in the CHRONC input file and represents an average value for the 50 mile region. VNFRM is used in the SITE input file and is calculated on a county-specific basis. Calculation of these values is presented below. o This case addresses Part 1 of the RAI (i.e., corrected VALWNF), and represents the "revised baseline" as specified in the RAI.
  • Case 5 o TIMDEC is escalated to one year (365 days) and CDNFRM is escalated to $100,000/person for DF=15 in the CHRONC input file. o VALWNF & VNFRM (including lost tourism and business) are escalated to 2005 values in the CHRONC and SITE input files, respectively.

o This case addresses Part 2(a) of the RAI.

  • Case 6 o TIMDEC is escalated to one year (365 days) and CDNFRM is escalated to $100,000/person for DF=15 in the CHRONC input file. o VALWNF & VNFRM without including lost tourism and business.

o This case is not used to support the RAI response.

  • Case 7 o VALWNF & VNFRM (including lost tourism and business) are escalated to 2005 values in the CHRONC and SITE input files, respectively.

o The dry deposition velocity, VDEPOS, is set to 0.003 m/sec in the ATMOS input file rather than the Reference 3 value of 0.010 m/sec. The value of 0.003m/sec is documented by the recent NRC's State-of-the-Art Reactor Consequence Analyses (SOARCA) Project to be the dominant or average value for use in SOARCA Revision 0 IP-RPT-16-00077, Rev. 0 Page 7 of 36 Page 6 of 35 021059-CALC-13106 Indian Point RAI CLl-16-07 (Reference

5) and is viewed as more representative of severe accident source terms than the value of 0.01 Om/sec used in the NUREG-1150 studies. o Similar to Case 4, Case 7 addresses Part 1 of the RAI (i.e., corrected VALWNF), and represents the "revised baseline" as specified in the RAI, except with an updated dry deposition velocity.
  • Case 8 o TIMDEC is escalated to one year (365 days) and CDNFRM is escalated to $100,000/person for DF=15 in the CH RO NC input file. o VALWNF & VNFRM (including lost tourism and business) are escalated to 2005 values in the CHRONC and SITE input files, respectively.

o The dry deposition velocity, VDEPOS, is set to 0.003 m/sec in the ATMOS input file rather than the Reference 3 value of 0.010 m/sec. o Similar to Case 5, Case 8 addresses Part 2(a) of the RAI (i.e., corrected VALWNF, increased TIMDEC & CDNFRM), as specified in the RAI, except with an updated dry deposition velocity.

The parameter value changes are applied to all IP2 and IP3 release categories for consistency, (i.e., not just the four worst release categories as specified in the RAI.) VALWNF Calculation This section documents the escalation of the Reference 3 VALWNF value to 2005 dollars for use in the MACCS2 sensitivity cases.

  • Original (without lost tourism/business)

VALWNF = $163,631/person (see Reference 4 Section 5.2.8). This was developed using SECPOP2000 and its economic database from the 1997 Census of Agriculture.

  • VALWNF with lost tourism I business=

$208,838/person (see Reference 4 Section 5.2.8). The lost tourism I business component is based on 2004 data. The lost tourism/business component is $45,207/person.

Consumer Price Index Values (Series CUUROOOOSAO, All Urban Consumers) are used for escalation purposes:

  • Annual 1997 CPI = 160.5
  • Annual 2004 CPI = 188.9
  • Annual 2005 CPI = 195.3
  • Escalation Factor 1997-2005

= 1.22

  • Escalation Factor 2004-2005

= 1.03 2005 VALWNF is calculated as follows:

  • VALWNF without lost tourism/business

= $163,631 /person

  • 1.22 = $199,630/person
  • Lost tourism I business component=

$45,207/person

  • 1.03 = $46,563/person
  • Total with lost tourism/ business (2005 dollars)=

$246, 193/person, rounded up to $247,000/person

  • Total without lost tourism/business (2005 dollars), rounded up= $200,000/person.

.. The original evaluations are documented in References 6 and 7. These SAMA candidate specific MACCS2 cases have been re-performed using the re-analyzed meteorology for the IPEC site per Reference 3 and the applicable cases above to address CLl-16-07. These cases and results are documented in Appendix A. Revision 0 IP-RPT-16-00077, Rev. 0 Page 9 of 36 Page 8 of 35 021059-CALC-13106 Indian Point RAI CLl-16-07 5.0 RESULTS Tables 1A and 1 B summarize the MACCS2 sensitivity case results for PDR and OECR for Units 2 and 3, respectively.

Comparison of Case 4 to the Base Case demonstrates that the escalation of the value of farm wealth to 2005 dollar values results in a modest OECR increase of approximately 9-10%. There is no appreciable change in the PDR. Similarly, comparison of Case 5 to the Base Case demonstrates that when the TIMDEC and CDNFRM values are increased to the maximum MACCS2 allowed values as stipulated in the RAI, along with the non-farm wealth escalation (2005 dollars values), the OECR increases approximately 126% for IP2 and 133% for IP3. The PDR increase is much smaller, approximately 12% for IP2 and 11% for IP3. As noted in the methodology section, the original IPEC SAMA analysis used a deposition velocity of 0.010 m/sec. The more recent NRC's SOARCA analysis (Reference

5) indicates that a value of 0.003 m/sec is more representative of an average value. When this value of 0.003 m/sec is employed, the RAI requested results in Cases 7 and 8 are appreciably lower than those results for a higher deposition velocity in Cases 4 and 5. Specifically, Case 7 shows that the lower deposition velocity more than offsets the increase associated with escalating the value of non-farm wealth to 2005 values. The OECR decreases approximately 10% for IP2 and 17% for IP3 when compared to the SAMA Base Case results. The PDR value changes a small amount (2.5% decrease for U2; 1.8% increase for U3). Case 8 demonstrates that when the TIMDEC and CDNFRM values are increased to the maximum MACCS2 allowed values as stipulated in the RAI, along with the non-farm wealth escalation (2005 dollars values), and the revised deposition velocity, th13 OECR increases approximately 91 % for IP2 and 82% for IP3. The PDR increase is much smaller, approximately 7% for IP2 and 10% for IP3. Tables 2A-21 and Tables 3A-31 present the detailed results (i.e., conditional and frequency weighted) for each of the sensitivity cases for PDR and OECR, for IP2 and IP3, respectively.

Note that the frequencies used to weight the conditional results are those from the SAMA Reanalysis (Table E.1-13) [3]. Results associated with SAMA candidate specific MACCS2 cases that have been re-performed using the reanalyzed meteorology per Reference 3 and the applicable cases above to address CLl-16-07 are documented in Appendix A.

SAMA CANDIDATE MACCS2 RUNS A.1. PURPOSE This appendix documents additional MACCS2 runs performed for specific SAMA candidates to model the potential benefit. These runs support the response to the NRC RAI pertaining to the NRC Commission Decision CLl-16-07 for IPEC. A.2. METHODOLOGY The original SAMA candidate evaluations are documented in References 6 and 7. These SAMA candidate specific MACCS2 cases are re-performed using the reanalyzed meteorology for the IPEC site per Reference 3 and the applicable cases in the main body of this document (i.e., cases 4, 5, 7, and 8) to address CLl-16-07.

Specifically, MACCS2 cases were performed to address the following SAMA candidates:

  • IP2 Phase II Candidate 020 -Revised the fission product release fractions for H-E, M-E, L-E release categories to those specified in "IP2 Radionuclide Release Results-Level1-20.xls". Original results for PDR and OECR are documented in NmetEC.xls".
  • IP3 Phase II Candidate 018 -Revised the fission product release fractions for H-E, M-E, L-E release categories to those specified in "IP3 Radionuclide Release Results-Level2-18.xls". Original results for PDR and OECR are documented in R-level130a.xls".
  • IP2 Tl-SGTR (RAI #5) -Revised the release attributes for the H-E release category to those specified in "IP2 Radionuclide Release Results-RA1#5.xls".

Original results for PDR and OECR are documented in "sumi2NS-noE-R-NmetEC-Base-RAl5.xls".

Release category frequencies for NCF and H-E are revised for this RAI.

  • IP3 Tl-SGTR (RAI #5) -Revised the release attributes for the H-E release category to those specified in "IP3 Radionuclide Release Results-Base-RAl#5.xls".

Original results for PDR and OECR are documented in "sumi3NS-noE-NmetEC-R-level130a-RAl5.xls".

Release category frequencies for NCF and H-E are revised for this RAI.

  • Spreadsheets identified above for the SAMA candidate cases were provided by Entergy consultant (L. Potts). For each sensitivity case, the MACCS2 results for total 50-mile offsite costs and 50-mile population dose for each release category are multiplied by the applicable release category frequency to calculate the OECR and PDR. The OECR and PDR of the various sensitivity cases are then compared against applicable reference cases to determine the impact of the revised parameters.

For each SAMA candidate, the following cases are performed.

  • SAMA Base Case Check o This case confirms that the results can be reproduced with the applicable MACCS2 files upon which the sensitivity cases are built. Revision 0 IP-RPT-16-00077, Rev. 0 Page 22 of 36 Page 21 of 35 021059-CALC-13106 Indian Point RAI CLl-16-07
  • Case 4 o VALWNF & VNFRM (including lost tourism and business) are escalated to 2005 values. VALWNF is used in the CHRONC input file and represents an average value for the 50 mile region. VNFRM is used in the SITE input file and is calculated on a county basis. Calculation of these values is presented below in the main report. o This case addresses Part 1 of the RAI (i.e., corrected VALWNF), and represents the "revised baseline" as specified in the RAI.
  • Case 5 o TIMDEC is escalated to one year (365 days) and CDNFRM is escalated to $100,000/person for DF=15 in the CHRONC input file. o VALWNF & VNFRM (including lost tourism and business) are escalated to 2005 values in the CHRONC and SITE input files, respectively.

o This case addresses Part 2(a) of the RAI.

  • Case 7 o VALWNF & VNFRM (including lost tourism and business) are escalated to 2005 values in the CHRONC and SITE input files, respectively.

o The dry deposition velocity, VDEPOS, is set to 0.003 m/sec in the ATMOS input file rather than the Reference 3 value of 0.010 m/sec. The value of 0.003m/sec is documented by the recent NRC's SOARCA Project to be the dominant or average yalue for use in SOARCA (Reference

5) and is viewed as more representative of severe accident source terms than the value of 0.01 Om/sec used in the NUREG-1150 studies. o Similar to Case 4, Case 7 addresses Part 1 of the RAI (i.e., corrected VALWNF), and represents the "revised baseline" as specified in the RAI, except with an updated dry deposition velocity.
  • Case 8 o TIMDEC is escalated to one year (365 days) and CDNFRM is escalated to $100,000/person for DF=15 in the CHRONC input file. o VALWNF & VNFRM (including lost tourism and business) are escalated to 2005 values in the CHRONC and SITE input files, respectively.

o The dry deposition velocity, VDEPOS, is set to 0.003 m/sec in the ATMOS input file rather than the Reference 3 value of 0.010 m/sec. o Similar to Case 5, Case 8 addresses Part 2(a) of the RAI (i.e., corrected VALWNF, increased TIMDEC & CDNFRM), as speeified in the RAI, except with an updated dry deposition velocity.

Cases 4, 5, 7, and 8 parameter value changes are applied to all IPEC release categories for consistency, (i.e., not just the four worst release categories as specified in the RAI.)
