Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities IP-RPT-16-00078 Revision 1 Page 4of112 1.0 Purpose This report documents a revised baseline SAMA cost-benefit analysis and SAMA cost-benefit sensitivity cases th.at were performed to support the response to an NRG Staff Request for Additional Information (RAI) pertaining to the NRG Commission Decision CLl-16-07 for Indian Point Energy Center (IPEC).
On May 4, 2016, the Commission issued a decision (CLl-16-07) in the Indian Point Nuclear Generating Unit Nos 2 and 3 (IP2 and IP3) license renewal proceeding, in which it directed the NRG 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 {TIM DEC) and cost to decontaminate non-farmland (CDNFRM) -- used in the MELCOR Accident Consequence Code (MAGGS) computer analyses, and that uncertainties in those input values could potentially affect the SAMA analysis cost-benefit conclusions. The Commission therefore directed the NRG staff to perform additional sensitivity analyses. (Reference 1)
In an RAI letter dated September 12, 2016, the NRG staff requested the following additional information (Reference 2):
- 1. Entergy Nuclear Operations, Inc. (Entergy) is requested to scale up the value of nonfarm wealth (VALWNF) input to the SAMA analysis' base-yeardollars (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:
- a. Apply the maximum values specified by the Commission and allowed by the MAGGS 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).
- b. 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.
- 3. Upon completing these additional analyses, Entergy is requested to submit the input and output files for the IP2 and IP3 MAGGS 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.
Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities I P-RPT-16-00078 Revision 1 Page 5of112 On February 8, 2017 Entergy filed an amendment to its pending license renewal application for Indian Point IP2 and IP3 to update the proposed term of the renewed licenses from 20 years for each unit to the periods ending April 30, 2024 for IP2 and April 30, 2025 for IP3 (Reference 10). Since the original license expiration dates were September 2013 for IP2 and December 2015 for IP3, the license renewal period has been changed to 11 years for IP2 and 10 years for IP3. Section 6.0 was added in Revision 1 of this report to describe the changes necessary for the SAMA cost-benefit sensitivities to reflect the revised license renewal period (11 years for IP2 and 10 years for IP3). Results of the revised analysis are provided in Section 7.0.
Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities 2.0 Summary of Results IP-RPT-16-00078 Revision 1 Page 6of112 The results of this analysis provide the following information requested in the RAI letter dated September 12, 2016 (Reference 2).
Section 6.0 was added in Revision 1 of this report to describe the changes necessary for the SAMA cost-benefit sensitivities to reflect the revised license renewal period (11 years for IP2 and 10 years for IP3). Results of the revised analysis are provided in Section 7.0 and show the following.
With an 11 year license renewal period for IP2 and a 10 year license renewal period for IP3, the baseline analysis has two less potentially cost-beneficial SAMAs (IP2-028, "Provide a portable diesel-driven battery charger," and IP2-062, "Provide a hard-wired connection to an SI pump from ASSS power supply," are not potentially cost-beneficial).
Also, Sensitivity Case 7 shows that with this new baseline and a change to VDEPOS along with escalation of VALWNF and VNFRM, SAMA IP2-044, "Use fire water system as backup for steam generator inventory," is not potentially cost-beneficial.
Finally, none of the sensitivity cases adds any potentially cost-beneficial SAMAs.
Response to RAI 1:
Entergy Nuclear Operations, Inc. (Entergy) scaled up the value of nonfarm wealth (VALWNF) input to the SAMA analysis' base-year (2005) dollars (Reference 4). VALWNF is used in the CHRONC input file and represents an average value for the 50 mile region.
Original (without lost tourism/business) VALWNF = $163,631/person. This was developed using SECPOP2000 and its economic database from the 1997 Census of Agriculture.
Original VALWNF with lost tourism l business= $208,838/person. 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:
Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities IP-RPT~16-00078 Revision 1 Page 7of112 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 Entergy also scaled up the individual county average VNFRM values of nonfarm wealth used in the SITE input file. The same approach and CPI escalation values developed for the VALWNF calculation are applied at the county level data. The values for each county are shown in Table 1 (Reference 4).

- 312573, Entergy re-ran the baseline analyses using the VALWNF and VNFRM values escalated to 2005 dollar values. Table 2 and Table 3 show the resulting Population Dose Risk (PDR) and Offsite Economic Risk (OECR) for the revised baseline. Comparison of these results to the baseline results in the 2009 analysis (Reference 3) shows a modest OECR increase of approximately 9-10% and no appreciable change in the PDR.

Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities Response to RAI 2.a:
IP-RPT-16-00078 Revision 1 Page 10 of 112 Using the revised baseline from RAI 1, Entergy ran supplemental sensitivity analyses using the input values specified. in CLl-16-07. Specifically, the maximum values specified by the Commission and allowed by the MACCS2 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) were
. applied. The parameter value changes are applied to all release categories for consistency, (i.e., not just the four worst release categories as specified in the RAI.)
I Table 4 and Table 5 show the PDR and OECR results when the TIMDEC and CDNFRM values are increased to the maximum MACCS2 allowed values as stipulated in the RAI, with the revised baseline.
Comparison of these results to the baseline results in the 2009 analysis (Reference 3) shows that the OECR increases approximately 126-133%. Also, the PDR increase is much smaller, approximately 11-
- 12%.

With an 11 year license renewal period for IP2 and a 10 year license renewal period for IP3, the baseline analysis has two less potentially cost-beneficial SAMAs (IP2-028, "Provide a portable diesel-driven battery charger," and IP2-062, "Provide a hard-wired connection to an SI pump from ASSS power supply," are not potentially cost-beneficial).
Also, Sensitivity Case 7 shows that with this new baseline and a change to VDEPOS along with escalation of VALWNF and VNFRM, SAMA IP2-044, "Use fire water system as backup for steam generator inventory," is not potentially cost-beneficial.
Finally, none of the sensitivity cases adds any potentially cost-beneficial SAMAs.

Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities Response to RAI 2.b:
IP-RPT-16-00078 Revision 1 Page 12of112 RAI 2.b gives Entergy 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 does not propose additional values for the TIMDEC and CDNFRM inputs. However, Entergy does propose an alternate value for variable VDEPOS, dry deposition velocity.
In Entergy's original SAMA analysis, the dry deposition velocity, VDEPOS, was set to 0.010 m/sec in the ATMOS input file. The recent NRC's State-of-the-Art Reactor Consequence Analyses (SOARCA)
Project found a value of 0.003m/sec to be the dominant or average value for use in SOARCA. Thus, 0.003m/sec is viewed as more representative than the value of 0.010m/sec used in the NUREG-1150 studies.
Entergy ran an alternative revised baseline using the VALWNF and VNFRM values escalated to 2005 dollar values, as described in the response to RAI 1, but with a VDEPOS value of 0.003m/sec (Reference 4). Table 6 and Table 7 show the resulting PDR and OECR for the alternative revised baseline. Comparison of these results to those in Table 2 and Table 3 shows that the lower deposition velocity more than offsets the increase associated with escalating the value of non-farm wealth to 2005 values. Comparison of these results to the baseline results in the 2009 analysis (Reference 3) shows that the OECR decreases between 10-17% compared to the SAMA basecase. The PDR value -
changes a small amount (2.5% decrease for IP-2; 1.8% increase for IP-3).

Using the alternative revised baseline (with escalated VALWNF and VNFRM and revised VDEPOS),
Entergy ran supplemental sensitivity analyses using the input values specified in CLl-16-07 (Reference 4). Specifically, 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) were applied. The parameter value changes are applied to all release categories for consistency, (i.e., not just the four worst release categories as specified in the RAI.) Table 8 and Table 9 show the PDR and OECR results, when the TIMDEC and CDNFRM values are increased to the maximum MACCS2 allowed values as stipulated in the RAI, with the alternate revised baseline.

Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities 5.0 Evaluation of Potentially Cost-Beneficial SAMAs for the Sensitivity Cases 5.1 MACCS2 Sensitivity Cases IP-RPT-16-00078 Revision 1 Page.19 of 112 In IP-RPT-16-00077 (Reference 4), a series of MACCS2 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.
More MACCS2 cases are documented in IP-RPT-16-00077 than are strictly required to addr~ss the RAI response. To expedite the evaluation, these additional cases were not carried through the SAMA cost-benefit analysis. Thus, the evaluation of potentially cost-beneficial SAMAs was only performed for the following MACCS2 cases.
For each IPEC unit, the following MACCS2 sensitivity cases are evaluated.
Case 0 o

This case confirms that the results of IP-RPT-09-00044 (Reference 3) can be reproduced with the applicable MACCS2 files upon which the sensitivity cases are built.
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.

5.2 Sensitivity Case 0 - Original Baseline A. Base Case for the Majority of the SAMAs The SAMA cost-benefit analyses in IP-RPT-09-00044 (Reference 3) were performed using un-linked spreadsheets in which some data was inserted manually. See Attachment 1 for a list of the _
spreadsheets. To facilitate the evaluation of multiple sensitivity cases, a combined spreadsheet was created, named "Case 0 IPEC SAMA Sensitivities."
This spreadsheet contains a worksheet, "Spreadsheet Conversion," documenting the conversion from the 2009 vintage worksheets and confirming that the combined spreadsheet calculates the 2009 benefit value for each SAMA. For a limited number of SAMAs, the combined spreadsheet calculates a slightly different benefit value from that calculated in 2009. These instances occur because the combined spreadsheet rounds values consistently for all of the SAMAs, which was not the case in the un-linked spreadsheets.
The combined spreadsheet facilitates sensitivity evaluations for the majority of the SAMAs because the PDR and OECR values from the sensitivity cases in IP-RPT-16-00077 (Reference 4) can be placed in worksheets "IP2 MACCS2 Output" and "IP3 MACCS2 Output" and the benefit values are automatically re-calculated and populated in columns C and D of the "Case# (cost-benefit)"
worksheet for comparison with the implementation cost estimates. Columns G and H of the "Case
- (cost-benefit)" worksheet contain the implementation cost estimates from IP-RPT-09-00044 (Reference 3) and NL-14-143 (Reference 5), respectively.
Indian Point RAI CLl-16~07 SAMA Cost-Benefit Sensitivities B. Base Case for SAMAs IP2-020 and IP3-018
- IP~RPT-16-00078 Revision 1 Page 21 of 112 SAMA IP2-020, "Route the discharge from the main steam safety valves through a structure where a water spray would condense the steam and remove most of the fission products," does not use the same MACCS2 output as the other SAMAs. As described in Appendix B of IP-RPT 00007 (Reference 6), analysis case 16 was used to evaluate SAMA IP2-020. A bounding analysis was performed by reducing SGTR accident progression source terms by a factor of 2.
The source terms used for the IP2-020 analysis are contained in file "IP2 SAMA Radionuclide Release Results-Level2-20.xls." A comparison of the IP2-020 source terms with those in Table A-1 O of IP-RPT-07-00007 shows that the only differences are the release fractions for the Early High (H-E), Early Medium (M-E), and Early Low (L-E) release categories. This is reasonable, since SGTR accidents are bypass events, which* contribute to early release categories.
Since the source term is different for this SAMA, the MACCS2 output is also different for this SAMA.
Therefore, the MACCS2 Case 0, Case 4, Case 5, Case 7, and Case 8 sensitivities were reevaluated with the IP2-020 source term information (Reference 4). An additional worksheet, "IP2-020 MACCS2 Output," was added to the combined spreadsheet, "Case 0 fPEC SAMA Sensitivities," to calculate the base case benefits and facilitate the sensitivity evaluations for IP2-020.
SAMA IP3-018, "Route the discharge from the main steam safety valves through a structure where a water spray would condense the steam and remove most of the fission products," does not use the same MACCS2 output as the other SAMAs. As described in Appendix B of IP-RPT-04-00008 *
(Reference 7), analysis case 14 was used to evaluate SAMA IP3-018. A bounding analysis was performed by reducing SGTR accident progression sol,lrce terms by a factor of 2.
- The source terms used for the IP3-018 analysis are contained in flle "IP3 SAMA Radionuclide Release Results-Level2-18.xls." A comparison of the IP3-018 source terms with those in Table A.1 O of IP-RPT-07-00008. shows that the only differences are the release fractions for the Early High (H-E), Early Medium (M-E), and Early Low (L-E) release categories. This is reasonable, since SGTR accidents are bypass events, which contribute to early release categories.
Since the source term is different for this SAMA, the MACCS2 output is also different for this SAMA.
Therefore, the MACCS2 Case 0, Case 4, Case 5, Case 7, and Case 8 sensitivities were reevaluated with the IP2-020 source term information (Reference 4). An additional worksheet, "IP3~
018 MACCS2 Output," was added to the combined spreadsheet, "Cas~ 0 IPEC SAMA Sensitivities," to calculate the base case benefits and facilitate the sensitivity evaluations for IP3-018.
I C. Altered Base Case for Tl-SGTR SAMAs Section 3.6 of IP-RPT-09-00044 (Reference 3) describes the analysis performed to evaluate the impact of more pessimistic assumptions regarding scenarios that involve the potential for a thermally induced steam generator tube rupture (Tl-SGTR). The NUREG-1570 full conditional induced SGTR value (0.25)for moderate tube degradation was applied to all high/dry sequences in the Level 2 model for each unit; in both station blackout and transient sequences.
Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities IP-RPT-16-00078 Revision 1 Page 22 of 112 In the Tl-SGTR analysis, twenty seven IP2 SAMAs and twenty two IP3 SAMAs were identified as potentially impacted by the Tl-SGTR assumption.
IP2 SAMAs: 1, 6, 18, 19, 20, 25, 26, 27, 28; 29,30,31, 32, 35, 39, 40, 42, 44, 46, 52, 54, 59, 60,61,62,65,66 IP3 SAMAs: 1, 16, 17, 18, 23, 24, 25, 26, 27, 28, 29, 30, 33, 38, 40, 42, 43, 55, 56, 58, 61, 62 Since IP2 SAMAs 28, 44, 54, 60, 61, 62 and 65 and IP3 SAMAs 55, 61 and 62 were previously determined to be potentially cost beneficial, they were not re-evaluated. Of the remaining SAMAs, a detailed evaluation was performed for those for which the cost outweighed the benefit by less than a factor of five. This screening criterion was applied to facilitate the re-evaluation by limiting it to
- those potentially impacted SAMA c,andidates with a realistic possibility of becoming cost-beneficial.
The unscreened IP2 SAMAs were SAMAs 1, 6, 25, 29, 40 and 52.
The unscreened IP3 SAMAs were SAMAs 1, 16, 18, 30, 40 and 43.

A comparison of the Tl-SGTR source terms with those in Table A-10 of IP-RPT-07-00007 and Table A.10 of IP-RPT 00008 shows that the only differences are the timing and release fractions for the Early High (H-E) release category. This is reasonable, si.nce high/dry sequences would be expected to contribute to this release category.
Since the source term is different for these SAMAs, the MACCS2 output is also different for these SAMAs. Therefore, the MACCS2 Case 0, Case 4, Case 5, Case 7, and Case 8 sensitivities were reevaluated with the Tl-SGTR source term information (Reference 4). Additional worksheets (IP2 Tl-SGTR Base, IP2 Tl-SGTR MACCS2 Output, IP3 Tl-SGTR Base, IP3 Tl-SGTR MACCS2 Output, and individual Tl-SGTR SAMA worksheets) were added to the combined spreadsheet, "Case 0 IPEC SAMA Sensitivities," to calculate the base case benefits and facilitate the sensitivity evaluations for the Tl-SGTR SAMAs.
5.3 Sensitivity Case 4-Revised Baseline (Escalated VALWNF and VNFRM)
Case 4 o
VALWNF & VNF.RM (including lost tourism and business) are escalated to 2005 v;alues. 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.
o This case addresses Part 1 of the RAI (i.e., corrected VALWNF), and represents the "revised baseline" as specified in the RAI.
The following steps were performed to evaluate Sensitivity Case 4.

- 4. The benefit values were automatically re-calculated and populated in columns C and D of the "Case 4 (cost-benefit)" worksheet for comparison with the implementation cost estimates.
- 5. Since Case 4 is considered a "new baseline," the SAMAs potentially impacted by the Tl-SGTR assumption were re-screened consistent with the screening in IP-RPT-09-00044 and described in Section 5.2.C above.
In the Tl-SGTR analysis, twenty seven IP2 SAMAs and twenty two IP3 SAMAs were identified as potentially impacted by the Tl-SGTR assumption.
IP2 SAMAs: 1, 6, 18, 19, 20, 25, 26, 27, 28, 29,30,31, 32, 35, 39, 40, 42, 44, 46, 52, 54, 59,60,61,62, 65,66 IP3 SAMAs: 1, 16,.17, 18, 23, 24, 25, 26, 27, 28, 29, 30, 33, 38, 40, 42, 43, 55, 56, 58, 61,62 Since IP2 SAMAs 28, 44, 54, 60, 61; *62 and 65 and IP3 SAMAs 55, 61 and 62 were previously determined to be potentially cost.beneficial, they were not re-evaluated. Of the remaining SAMAs, a detailed evaluation was performed for those for which the cost outweighed the benefit by less than a factor of five. [Column J of the "Case 4 (cost-benefit)"
worksheet was*used for this screening.] This screening criterion was applied to facilitate the re-evaluation by limiting it to those potentially impacted SAMA candidates with a realistic possibility of becoming cost-beneficial.
In Case 0, the unscreened IP2 SAMAs were SAMAs 1, 6, 25, 29, 40 and 52.
In Case 4, the unscreened IP2 SAMAs are SAMAs 1, 25, 29, 40 and 52.
In Case 0, the unscreened IP3 SAMAs were SAMAs 1, 16, 18, 30, 40 and 43.
In Case 4, the unscreened IP3 SAMAs are SAMAs 1, 16, 17, 30, 40 and 43.

- 6. As described in Section 5.2.C above for the other Tl-SGTR SAMAs, an additional worksheet was added to the Case 4 spreadsheet to evaluate the IP3-017 Tl-SGTR benefit. The "Case 4 (cost-benefit)" worksheet was adjusted accordingly.
- 7. SAMA IP2-006 does not meet the screening criterion in Case 4 due to rounding of the benefit values. However, the Tl-SGTR analysis for this SAMA was retained* in the Case 4 spreadsheet.
- 8. SAMA IP3-018 does not meet the screening criterion in Case 4 due to the new implementation cost estimate reported in NL-14-143 (Reference 5). Nevertheless, the Tl-SGTR analysis for this SAMA was retained in the Case 4 spreadsheet. This SAMA does not become cost-beneficial in Case 4 or Case 5, so there is no impact from keeping the Tl-SGTR analysis.
5.4 Sensitivity Case 5-Revised TIMDEC and CDNFRM (with Escalated VALWNF and VNFRM).
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 and 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.
The following steps were performed to evaluate Sensitivity Case 5.
- 2. Renamed worksheet "Case 4 (cost-benefit)" to "Case 5 (cost-benefit)."
- 3. Cleared the contents of columns D and F and revised equations in column I to use the values in columns C and E for comparison. Since Case 5 is a sensitivity analysis on the revised baseline from Case 4, the 95th percentile uncertainty sensitivity does not also need to be calculated. Also, deleted column J since the Tl-SGTR screening was performed in Case 4.
- 4. Copied PDR and OECR values from the sensitivity cases in IP-RPT-16-00077 into the appropriate worksheets in Case 5 IPEC SAMA Sensitivities.xlsx (see table below).

- 5. The benefit values were automatically re-calculated and populated in columns C and E of the "Case 5 (cost-benefit)" worksheet for comparison with the implementation cost estimates.
- 6. A few of the IP2 SAMAs showed a negative benefit in the Case 5 results. This occurred because the SAMAs had no benefit and the release mode frequencies for the individual SAMAs carried more digits than the release mode frequencies for the IP2-Base Benefit.
The release mode frequencies from the IP2-Base Benefit worksheet were copied over the release mode frequencies in worksheets IP2-033, IP2-046, IP2-047, IP2-051, IP2-055, and IP2-058. This corrects the SAMA benefits in the Case 5 (Cost-Benefit) worksheet so that they are zero, rather than negative.
5.5 Sensitivity Case 7 -Alternate Revised Baseline (Escalated VALWNF and VNFRM and revised VDEPOS)
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 IP-CALC-09-00265 (Reference 8) value of 0.01 O 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 and is viewed as more representative 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., escalated VALWNF),.and represents the "revised baseline" as specified in the. RAI, except with an updated dry deposition velocity.
The following steps were performed to evaluate Sensitivity Case 7.
- 2. Renamed worksheet "Case O (cost-benefit)" to "Case 7 (cost-benefit)" and deleted columns J and K from this worksheet.
- 3. Copied PDR and OECR values from the sensitivity cases in IP-RPT-16-00077 into the appropriate worksheets in Case 7 IPEC SAMA Sensitivities.xlsx (see table below).

- 4. The benefit values were automatically re-calculated and populated in columns C and D of the "Case 7 (cost-benefit)" worksheet for comparison with the implementation cost estimates.
- 5. A few of the IP2 SAMAs showed a negative benefit in the Case 7 results. This occurred because the SAMAs had little or no benefit and the release mode frequencies for the individual SAMAs carried more digits than the release mode frequencies for the IP2-Base Benefit. The release mode frequencies from the IP2-Base Benefit worksheet were copied over the release mode frequencies in worksheets IP2-012, IP2-013, IP2-016, IP2-033, IP2-046, IP2-047, IP2-051, IP2-055, and IP2-058. Also, the IP2-Base Benefit release frequencies for the non-NCF release modes were copied over the release mode frequencies in worksheet IP2-067. This corrects the SAMA benefits in the Case 5 (Cost-Benefit) worksheet so that they are non-negative.
- 6. Since Case 7 is a proposed, alternate "new baseline," the SAMAs potentially impacted by the Tl-SGTRassumption were re-screened consistent with the screening in IP-RPT 00044 and described in Section 5.2.C above.
In the Tl-SGTR analysis, twenty seven IP2 SAMAs and twenty two IP3 SAMAs were identified as potentially impacted by the Tl-SGTR assumption.
IP2 SAMAs: 1, 6, 18, 19, 20, 25, 26, 27, 28, 29,30,31, 32, 35, 39, 40, 42, 44, 46, 52, 54, 59, 60,61,62, 6~66 IP3 SAMAs: 1, 16, 17, 18, 23, 24, 25, 26, 27, 28, 29, 30, 33, 38, 40, 42, 43, 55, 56, 58, 61,62 Since IP2 SAMAs 28, 44, 54, 60, 61, and 65 and IP3 SAMAs 55, 61 and 62 were previously determined to be potentially cost beneficial, they were not re-evaluated. Of the remaining SAMAs, a detailed evaluation was performed for those for which the cost outweighed the benefit by less than a factor of five. [Column J of the "Case 7 (cost-benefit)" worksheet was used for this screening.] This screening criterion was applied to facilitate the re-evaluation by limiting it to those potentially impacted SAMA candidates with a realistic possibility of becoming cost-beneficial.
In Case 0, the unscreened IP2 SAMAs were SAMAs 1, 6, 25, 29, 40 and 52.
In Case 7, the unscreened IP2 SAMAs are SAMAs 1, 25, 40, 52, and 62.
In Case 0, the unscreened IP3 SAMAs were SAMAs 1, 16, 18, 30, 40 and 43.
In Case 7, the unscreened IP3 SAMAs are SAMAs 1, 16, 30, 40 and 43.
- 7. As described in Section 5.2.C above for the other Tl-SGTR SAMAs, an additional worksheet was added to the Case 7 spreadsheet to evaluate the IP2-062 Tl-SGTR benefit. The "Case 7 (cost-benefit)" worksheet was adjusted accordingly. [IP2-062 was not evaluated for Tl-SGTR in Case 0 because it was cost-beneficial in Case 0. However, IP2-062 is not cost-beneficial in Case 7, so it is included in the T_l-SGTR evaluation.]

- 8. Similar to Case 4, SAMAs IP2-006, IP2-029, and IP3-018 do not meet the screening criterion in Case 7. However, the Tl-SGTR analyses for these SAMAs were retained in the Case 7 spreadsheet.
5.6 Sensitivity Case 8-Alternate RevisedTIMDEC and CDNFRM (with Escalated VALWNF and VNFRM and revised VDEPOS)
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 IP-CALC-09-00265 (Reference 8) value of 0.010 m/sec.
o Similar to Case 6, 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 following steps were performed to evaluate Sensitivity Case 8.
- 2. Renamed worksheet "Case 7 (cost-benefit)" to "Case 8 (cost-benefit)."
- 3. Cleared the contents of columns D and F and revised equations in column I to use the values in columns C and E for comparison. Since Case 8 is a sensitivity analysis on the alternate revised baseline in Case 7, the 95th percentile uncertainty sensitivity does not also need to be calculated. Also, deleted column J since the Tl-SGTR screening was performed in Case 7.
- 4. Copied PDR and OECR values from the sensitivity cases in IP-RPT-16-00077 into the appropriate worksheets in Case 8 IPEC SAMA Sensitivities.xlsx (see table below).

' i 1-1 Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities 6.0 Revision to Reflect Shortened License Renewal Period IP-RPT-16-00078 Revision 1 Page 28 of 112 On February 8, 2017 Entergy filed an amendment to its pending license renewal application for Indian Point IP2 and IP3 to update the proposed term of the renewed licenses from 20 years for each unit to the periods ending April 30, 2024 for IP2 and April 30, 2025 for IP3 (Reference 10). Since the original license expiration dates were September 2013 for IP2 and December 2015 for IP3, the license renewal period has been changed to 11 years for IP2 and 10 years for IP3. Section 6.0 describes the changes necessary for the SAMA cost-benefit sensitivities to reflect the revised license renewal period (11 years for IP2 and 10 years for IP3). Results of the revised analysis are provided in Section 7.0.
The license renewal period impacts the SAMA analysis in two ways. First, it defines the year to which the population projections for the 50-mile region around the plant are extrapolated. Second, it is used in the calculations of onsite and offsite exposure costs and economic costs following a severe accident to take into account the time value of money.
For the Indian Point SAMA analyses, the population in the 50-mile region was projected to the year 2034 to encompass the license renewal period for both units (Reference 3). With a shorter license renewal period (ending in 2024 for IP2 and 2025 for IP3), the population in the region would generally be expected to be lower. However, the many MACCS2 cost input values are based on present dollars not future dollars (Reference 11 ), so they are not impacted by the duration of the license renewal period. Since the only change to the MACCS2 analyses would be the population, and re-projecting the population is a time consuming task, Entergy has decided to conservatively retain the 2034 population in Revision 1 of this report. Therefore, the results of the MACCS2 sensitivity cases described in Section 5.1 and presented in Tables 2 through 9 remain unchanged. Also, the escalated VALWNF described in Section 2.0 and the VNFRM values in Table 1 remain unchanged.
This revision accounts for the impact on the onsite and offsite exposure costs and economic costs following a severe accident from the reduced license renewal period (11 years for IP2 and 10 years for IP3) as describe below.
6.1 On-site and Offsite Exposure and Economic Costs Following a Severe Accident The onsite and offsite exposure and economic costs following a severe accident were calculated as shown in Section 3:2.5 of Reference 3. They are recalculated below using the new license renewal period for each unit. The parameter "tt" is used for the license renewal period (years) and is included in several of the equations to take into account the time value of money. These calculations provide the costs for each unit without implementation of any SAMAs. Thus, they establish the maximum benefit that a SAMA could achieve if it eliminated all risk due to at-power internal events. Each of the cost
- categories is discussed followed by a summary table for each unit.
6.1.1 Accident-Related Off-Site Dose Costs (APE)
The Level 3 baseline analysis resulted in an annual off-site exposure risk of 87.4 person-rem for IP2 and 94.8 person-rem for IP3. This value was converted to its monetary equivalent (dollars) via application of the $2,000 per person-rem conversion factor from the Regulatory Analysis Technical Evaluation Handbook (Reference 12). Th~ monetary equivalent was then discounted to present value using the following equation.
- Where, Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities IP-RPT-16-00078 Revision 1 Page 29 of 112 APE = monetary value of accident risk avoided from population does, after discounting ($)
R = monetary equivalent of unit dose ($/person-rem)
F = accident frequency (events/year)
Op = population dose factor (person-rem/event) s =status quo (current conditions)
A = after implementation of proposed action r = discount rate tt =license renewal period (years).
Because there are eight accident releases considered in this study, the product FDp which represents population dose risk (PDR), was estimated by summing the product of the release frequency of each accident release and population dose over all eight releases.
For IP2, using an 11-year license renewal period, a 7% discount rate, assuming FA is zero, and the baseline PDR value of 87.4 person-rem/yr resulted in the mon~tary equivalent value of $1,340,933.
For IP3, using a 10-year license renewal period, a 7% discount rate, assuming FA is zero, and the baseline PDR value of 94.8 person-rem/yr resulted in the monetary equivalent value of $1,363,535.
6.1.2 Accident-Related Off-Site Property Damage Costs (AOC)
The Level 3 baseline analysis resulted in an annual off-site economic risk monetary equivalent of
$212,000 for IP2 and $261,000 for IP3. This value was discounted in the same manner as the public health risks in accordance with the following equation:
- Where, AOC = monetary value of risk avoided from off-site property damage, after discounting ($)
Po = off-site property loss factor ($/event)
F = accident frequency (events/year)
S =status quo (current conditions)
A = after implementation of proposed action r = discount rate
Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities tt =-license renewal period (years)
IP-RPT-16-00078 Revision 1 Page 30 of 112 The product FPo, which represents off-site economic cost risk (OECR), was estimated by summing the product of the release frequency of each accident release and off-site economic costs over all eight releases.
For IP2, using previously defined values and the baseline OECR value of $212,000/yr, the resulting monetary equivalent is $1,626,303.
For IP3, using previously defined values and the baseline QECR value of $261,000/yr, the resulting monetary equivalent is $1,877,018.
6.1.3 Total Accident-Related Occupational Exposures (AOE)
The values for occupational exposure associated with severe accidents were not derived from the PSA model, but from information in the Regulatory Analysis Technical Evaluation Handbook (Reference 12).
The values for occupational exposure consist of "immediate dose" and "long-term dose." The best estimate value provided for immediate occupational dose is 3,300 person-rem, and long-term occupational dose is 20,000 person-rem (over a ten year clean-up period). The following equations were used to estimate monetary equivalents.
Immediate Dose
- Where, W1o =monetary value of accident risk avoided from immediate doses, after discounting*($)
10 = immediate occupational dose R = monetary equivalent of unit dose ($/person-rem)
F =accident frequency (events/year)
D10 = immediate occupational dose (person-rem/event)
S =status quo (current conditions)
A = after implementation of proposed action r = discount rate -
tt = license renewal period (years)
The values used in the analysis were:
R = $2,000/person-rem r = 0.07
Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities
. D10 = 3,300 person-rem/accident tt = 11 years for IP2 and 10 years for IP3 IP-RPT-16-00078 Revision 1 Page 31 of 112 For the basis discount rate, assuming FA is zero, the bounding monetary value of the immediate dose is as follows.
For IP2, the baseline GDF is 1.79X10-5/ry, and W10 = $906.
For IP3, the baseline GDF is 1.15X1 o-5/ry, and W10 = $546.
Long-Term Dose
- Where, WLTo = monetary value of accident risk avoided from long-term doses, after discounting ($);
L TO = long-term occupational dose m = years over which long-term doses accrue R =monetary equivalent of unit dose ($/person-rem)
F = accident frequency (events/year)
DLTo = long-term occupational dose (20,000 person-rem/event)
S =status quo (current conditions)
A = after implementation of proposed action r = discount rate tt =license renewal period (years)
The values used in the analysis were:
R = $2,000/person-rem r = 0.07 DLrn = 20,000 person-rem/accident m = 10 years tt = 11 years for IP2 and 10 years for IP3 For the basis discount rate, assuming FA is zero, the bounding monetary value of the long-term dose associated with accident risk is as follows.
For IP2, the baseline GDF is 1.79X10-5/ry, and WLrn = $3,950.
Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities For IP3, the baseline GDF is 1*.15X10-5/ry, and WLrn = $2,379.
Total Occupational Exposures I P-R.PT-16-00078 Revision 1 Page 32 of 112 The total exposure (AOE) is obtained by summing the immediate monetary value of on-site exposure after discounting (W10) and the long-term monetary value of on-site exposure after discounting (WLTo).
The bounding value for occupational exposure (AOE) for IP2 is $4,856.
The bounding value for occupational exposure (AOE) for IP3 is $2,925.
6.1.4 Averted Costs Associated with Accident-Related On~Site Property Damage (AOSC)
Clean-up/Decontamination The total cost of clean-up/decontamination of a power reactor facility subsequent to a severe accident is estimated in the Regulatory Analysis Technical Evaluation Handbook (Reference 12) to be $1.5X109; this same value was adopted for these analyses. Considering a 10-year cleanup period, the present value of this cost is:
- Where,
(
Ccv) (1 - e-rm)
PVcv = -
~. ---
m r
PV co = present value of the cost of cleanup/deco~tamination ($)
CD = clean-up/decontamination Ceo= total cost of the cleanup/decontamination effort ($1.5X109) m =cleanup period (10 years) r = discount rate Based upon the values previously assumed, PVco = $1.08E+9.
This cost is integrated over the term of the proposed license extension as follows:
- Where, (1-e-rt1)
Ucv = PVcv----
r Uco = total cost of clean-up/decontamination over the life of the plant tt = license renewal period (years)
Using the 7% discount rate and tt = 11 years for IP2 and 10 years for IP3, the Uco for IP2 is $8.29E+9 and the Uco for IP3 is $7.77E+9.
Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities IP-RPT-16-00078 Revision 1 Page 33 of 112 Replacement Power.Costs Replacement power costs were estimated in accordance with the Regulatory Analysis Technical
_Evaluation Handbook (Reference 12). Since replacement power will be needed for the time period following a sever accident, for the remainder of the expected generating plant life, long-term power replacement calculations have been used. The present value_of replacement power was estimated as follows:
- Where,
- ($1.2x10B) (
-rt )2 PVRP -
1-e t
r PVRP = present value of the qp_~t of replacement power for a single event ($);
r = discount rate tt = license renewal period (years)
The $1.2x108 value has no intrinsic meaning, but is a substitute for a string of non-constant replacement power costs that occur over the lifetime of a "generic" reactor after an event. This equation was developed in the Regulatory Analysis Technical Evaluation Handbook (Reference 12) for discount rates between 5% and 10% only.
Using the 7% discount rate and tt = 11 years for IP2 and 10 years for IP3, the PVRP for IP2 is $4.94E+8 and the PVRP for IP3 is $4.34E+8.
To account for the lifetime of the facility, URP was then calculated from PVRP as follows:
- Where, PV U
RP (1
-rtt)2 RP ---
-e r
URP = present value of the cost of replacement power over the remaining life ($);
r = discount rate tt = license renewal period (years)
Based upon the values previously assumed, and the power correction factor of 1.177 discussed below, the URP for IP2 is $2.82E+9 and the URP for IP3 is $3.28E+9.
Since net generation can vary based on plant demands, a power level of 1071 MWe, which reflects typical gross generation levels, was used to conservatively bound the net generated power that would need to be replaced at eithi;ir IP2 or IP3. Thus, a correction factor to account for the difference in typical gross power generation level used for IP2 and IP3, and the generic reactor described in the Regulatory Analysis Technical Evaluation Handbook (i.e., 1071 MWe/91 OMWe = 1.177) was used.

Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities IP-RPT-16-00078 Revision 1 Page 36 of 112 6.2 Evaluation of Potentially Cost-Beneficial SAMAs for the Shortened License Renewal Period Sensitivity Cases The equations in Section 6.1 are already within the analysis case spreadsheets, which were created as described in Sections 5.2 through 5.6. Within each analysis case spreadsheet, in the worksheets labeled "IP2-Base Benefit" and "IP3-Base Benefit", cell B-3 contains the value for the license renewal period (tt). Likewise, in the worksheets for the individual SAMAs, cell B-3 contains the value for the license renewal period (tt). Thus, the analyses performed in Sections 5.2 and 5.6 are revised to reflect the new license renewal period by changing the value of tt in these worksheets. They were revised as follows.
6.2.1 Sensitivity Case O - Shortened License Renewal Period Baseline The baseline calculations in Section 5.2 were revised as follows to reflect the revised license renewal period (11 years for IP2 and 10 years for IP3).

Indian Point RAI CLl-16-07 SAMA Cost-Benefit Sensitivities 7.0 Conclusions for Shortened License Renewal Period 7.1 Sensitivity Case 0 - Shortened License Renewal Period Baseline IP-RPT-16-00078 Revision 1 Page 39 of 112 The baseline analysis shows that two SAMAs that were potentially cost-beneficial with a 20 year license renewal period are not potentially cost-beneficial using the shortened license renewal period of 11 years for IP2 and 10 years for IP3. Specifically, SAMAs IP2-028, "Provide a portable diesel-driven battery charger," and IP2-062, "Provide a hard-wired connection to an SI pump from ASSS power supply," are not potentially cost-beneficial with the shortened license renewal period.
Table 10 provides the Sensitivity Case 0 (Baseline) SAMA results using the shortened license renewal period.
7.2 Sensitivity Case 4-Shortened License Renewal Period Revised Baseline (Escalated VALWNF and VNFRM)
The revised baseline with escalation of VALWNF and VNFRM did not result in additional potentially cost-beneficial SAMAs.
l Table 11 provides the Sensitivity Case 4 SAMA results using the shortened license renewal period.
7.3 Sensitivity Case 5-Shortened License Renewal Period Revised TIMDEC and CDNFRM (with Escalated VALWNFand VNFRM)
Increasing TIMDEC and CDNFRM (with escalated VALWNF and VNFRM) did not result in additional potentially cost-beneficial SAMAs.
Table 12 provides the Sensitivity Case 5 SAMA results using the shortened license renewal period.
7.4 Sensitivity Case 7 - Shortened License Renewal Period Alternate Revised Baseline (Escalated VALWNF and VNFRM and revised VDEPOS)
Sensitivity Case 7 shows that one SAMA*that was potentially cost-beneficial in the Shortened License Renewal Period Baseline (Case O above) is not potentially cost-beneficial with the change to VDE'.POS along with escalation of VALWNF and VNFRM. Specifically, SAMA IP2-044, "Use fire water system as backup for steam generator inventory," is not potentially cost-beneficial in this case with the shortened license renewal period.
Sensitivity Case 7 did not result in additional potentially cost-beneficial SAMAs.
Table 13 provides the Sensitivity Case 7 SAMA results using the shortened license renewal period.
7.5 Sensitivity Case 8-Shortened License Renewal Period Alternate Revised TIMDEC and CDNFRM (with Escalated VALWNF and VNFRM and revised VDEPOS)
Increasing TIMDEC and CDNFRM (with escalated VALWNF and VNFRMand revised VDEPOS) did not result in additional potentially cost-beneficial SAMAs.
