QUESTION NO. : 02.03.04-6

The list of atmospheric dispersion factor (x/Q) key site parameters shown in DCD Tier 1, Table2.1-1 (sheet 4 of 7) and Tier 2, Table 2.0-1 (Sheet 3 of 8) include ground-level containmentreleases to the Class 1 E electrical room HVAC intake for MCR inleakage. Please explain whythere are no x/Q key site parameter values provided for ground-level containment releases to theother MCR inleakage locations (i.e., reactor building door and auxiliary building intake).

ANSWER:

It is an editorial mistake. The concept of how to determine these MCR inleakage x/Q values issame as the other x/Q values like plant vent release. As written in DCD Tier 1, Table 2.1-1 note 3and Tier 2, Table 2.0-1 note 3, the x/Q values of ground-level containment releases to the Class1 E electrical room HVAC intake for MCR inleakage is the largest value in comparison with theother MCR inleakage locations (i.e., reactor building door and auxiliary building intake).Therefore,the expression "to class 1 E electrical room HVAC intake" described in Table 2.1-1 (sheet 4 of 7)and Tier 2, Table 2.0-1 (Sheet 3 of 8) is not necessary and then these Tables will be changed asshown in Table2.1-1 (sheet 4 of 7) of Appendix 1 and Table 2.0-1 (sheet 3 of 8) of Appendix2.attached at the end of the responses.

The largest x/Q value is considered for dose calculation in DCD. In fact the site specificmeteorological data will be used for calculation of x/Q values in COL, we don't know which x/Qvalue of them is the largest in COL. However, it is acceptable if the x/Q value of DCD bounds thex/Q values of COL in either case.In the US-APWR DCD, the condition for x/Q values calculation for every MCR inleakage locationfor COL applicant are written in DCD Tier 2 Rev 2, Table 2.3-1, 2.3-2, 2.3-3 and 2.3.4-1 through2.3.4-7. There is no need to show the x/Q values of the other MCR inleakage locations andadditional information for calculation of these x/Q values in DCD.

Impact on DCDThe DCD will be changed to incorporate the following:- Change the DCD Tier 1, Table 2.1-1 and Tier2, Table 2.0-1 to correct the expression of

DCD Tier 2, Tables 15A-18 through 15A-24 present the atmospheric dispersion (x/Q) values usedto evaluate MCR and TSC dose consequences from a number of different design basis accidentevents. The information presented in Table 15A-18 (sheet 1 of 2) includes the horizontal andvertical distances between the source and receptors for the steam system piping failure analysis.This type of information is not presented in Tables 15A-19 through 15A-24 for the other designbasis accident events. Instead, the information necessary to calculate MCR and TSC x/Q values(include source-receptor distances) is provided in DCD Tier 2, Tables 2.3-1 through 2.3-3 andTables 2.3.4-1 through 2.3.4-7. Consequently, please consider deleting the source/receptorhorizontal and vertical distance information from Table 15A-1 8 (sheet 1 of 2).

ANSWER:

We agree with what you pointed out. The information of the horizontal and vertical distancesbetween source and receptors for the steam system piping failure analysis in DCD Tier 2, Table15A-1 8 (sheet 1 of 2) will be deleted, because the same information is included in DCD Tier 2,Tables 2.3-1 through 2.3-3 and Tables 2.3.4-1 through 2.3.4-7. DCD Tier 2, Table 15A-1 8 (sheet 1of 2) will be changed as shown in Table 15A-1 8 (sheet 1 of 2) of Appendix 2 attached at the end ofthe responses.

Impact on DCDThe DCD will be changed to incorporate the following:- Change the DCD Tier 2, Table 15A-1 8 to delete the information of the horizontal and vertical

distances between source and receptors for the steam system piping failure analysis.(SeeSheet 1 of 2 on page 02.03.04-70)

DCD Tier 2, Table 2.3-3, presents receptor height data for use by COL applicants in generatingsite-specific MCR and TSC x/Q values. Different values for the heights to the lower and upperlimits are presented for two sets of receptors: the reactor building door (west) and the auxiliarybuilding/TSC HVAC intake (north and south). Please explain why the heights to the lower limit arehigher than the heights to the upper limit for these two sets of receptors.

ANSWER:

It is an editorial mistake in items of Table 2.3-3 as you pointed out. In DCD Tier 2 Rev 2, Table2.3-3 shows the receptor heights information. The height to the lower limit of every receptor shouldbe lower than the height to the upper limit for every receptor. Therefore Table 2.3-3 will bechanged as shown in Table 2.3-3 attached at the end of the responses.

Impact on DCDThe DCD will be changed to incorporate the following:- Change the DCD Tier 2, Table 2.3-3 to correct the expression of items. (See on page

DATE OF RAI ISSUE: 312412010


The following set of comments primarily refers to DCD Tier 2, Tables 2.3.4-1 through 2.3.4-7.

a. DCD Tier 2, Section 2.3.4 states that (1) the 0-8 hr MCR and TSC x/Q values were calculatedbased, in part, on the diffusion equations contained in the ARCON96 atmospheric dispersionmodel and (2) the 8-24 hr, 24-96 hr, and 96-720 hr MCR and TSC x/Q values were derivedfrom the 0-8 hr x/Q values by adjusting for long-term meteorological averaging of wind speedand wind direction as described in Section C.4.4 of Regulatory Guide 1.194. The long-termmeteorological averaging was generally accomplished by multiplying the 0-8 hr x/Q values bycombined wind speed and wind direction correction factors of (1) 0.59 to obtain the 8-24 hr x/Qvalues, (2) 0.38 to obtain the 24-96 hr x/Q values, and (3) 0.17 to obtain the 96-720 hr x/Qvalues.

SRP 2.3.4 states that the site parameters postulated for a standard design certification shouldbe representative of a reasonable number of sites that have been or may be considered for aCOL application. In order to confirm that the US-APWR MCR and TSC x/Q values listed as keysite parameters in DCD Tier 1, Table 2.1-1 and DCD Tier 2, Table 2.0-1 are representative of areasonable number of sites that have been or may be considered for a COL application, thestaff generated a set of site-specific MCR and TSC x/Q values using hourly meteorologicaldata provided in support of the four docketed ESP applications (North Anna, Clinton, GrandGulf, and Vogtle). The staff executed the ARCON96 computer code with a subset of thesource/receptor information presented in DCD Tier 2, Tables 2.3.4-1 through 2.3.4-7 assumingthe US-APWR plant north was aligned to true north at each site. The staff found that theUS-APWR 0-8 hour, 8-24 hour, and 1-4 day x/Q values were bounding in all cases, but theUS-APWR 4-30 day x/Q values were not bounding for three out of the four sites. This impliesto the staff that the use of a 96-720 hr combined wind speed and wind direction long-termaveraging correction factor of 0.17 with the ARCON96 diffusion equations does not produceappropriate results.

Consequently, please consider increasing the 96-720 hr MCR and TSC x/Q values listed askey site parameters in DCD Tier 1, Table 2.1-1 and DCD Tier 2, Table 2.0-1 to ensure theybound a reasonable number of sites that have been or may be considered for a COLapplication.

02.03.04-5

b. Consider revising DCD Tier 2, Section 2.3.4 (last sentence on page 2.3-2) to appropriatelyreference DCD Tier 2, Tables 2.3.4-1 through 2.3.4-7.

c. Please review the title of Table 2.3.4-3 (sheet 9 of 11) shown on page 2.3-35 and correct asnecessary.

d. Regarding Table 2.3.4-3 (Sheet 9 of 11 on page 2.3-35), should the lateral and verticaldiffusion coefficients for the ground level containment release point to the north and southTSC HVAC intakes and to the north and south auxiliary building HVAC intakes be listed as7.98 meters and 5.03 meters, respectively, instead of 0 meters?

e. The source to receptor horizontal distances between the west main steam relief valve and thesouth TSC HVAC intake listed in the following tables are inconsistent:

Table 2.3.4-1 (Sheet 11 of 12 on page 2.3-17)Table 2.3.4-2 (Sheet 7 of 8 on page 2.3-25)Table 2.3.4-3 (Sheet 10 of 11 on page 2.3-36)

f. Please consider deleting Footnote 6 to DCD Tier 2, Tables 2.3.4-1 through 2.3.4-7. Theinformation presented in this footnote describes the process used by MHI to derive theUS-APWR MCR and TSC key site parameter x/Q values; this same information is alsopresented in DCD Tier 2, Section 2.3.4. The intent of DCD Tier 2, Tables 2.3.4-1 through2.3.4-7, is to provide the plant configuration data required by COL applicants to calculatesite-specific MCR and TSC x/Q values. To include information in these tables related to themethodology used by MHI to derive the US-APWR x/Q site parameter values can beconfusing to a COL applicant.

ANSWER:

a. We agree with what you pointed out. In accordance with our pre-analysis, we knew that anumber of existing US site plants where 96-720 hr x/Q values are not bounded by the x/Qvalue of the DCD increases in comparison with in case of the other time average x/Q values.As you pointed out, the 96-720hr x/Q value of the DCD should be representative of areasonable number of existing sites. But the 96-720 hr x/Q value gives little influence to thedose calculation result because of the small value.

For COL applicants, it is desirable to raise the 96-720 hr x/Q value of the DCD. Therefore, thevalue of the 96-720 hr x/Q will be changed to 1.5 times of the present 96-720hr x/Q value. The1.5 times x/Q value bounds the site parameter of North Anna, Clinton, Grand Gulf and Vogtlein FSAR as shown in the Figure 02.03.04-9-1. Therefore the 96-720 hr x/Q values of thefollowing DCD Tables should be changed as shown in the corresponding Tables of Appendix 1and 2 attached at the end of the responses.- DCD Tier 1 Rev 2, Table 2.1-1 DCD (sheet 3 of 7) through Table 2.1-1 (sheet 6 of 7)- DCD Tier 2 Rev 2, Table 2.0-1 (sheet 2 of 8) through Table 2.0-1 (sheet 6 of 8)- DCD Tier 2 Rev 2, Table 2.3.4-1 through 2.3.4-7- DCD Tier 2 Rev 2, Table 15A-1 8 through 15A-24.Some changed 96-720 hr x/Q values in the above Tables do not exactly correspond to 1.5times of the present 96-720 hr x/Q values due to the rounding of fractions.

b. It is an editorial mistake. The table reference at the last sentence on page 2.3-2 in DCD Tier 2Rev 2 will be changed from "Table 2.3-1 to 2.3-4" to "Tables 2.3.4-1 through 2.3.4-7" asfollows."The necessary data to calculate x/Q values of MCR and TSC by using ARCON96 are shownin Table 2.3.4-1 through 2.3.4-7.".

c. It is an editorial mistake. The title of Table 2.3.4-3 (sheet 9 of 11) in DCD Tier 2 Rev 2 includesunnecessary words at the end of it. The title of Table 2.3.4-3 (sheet 9 of 11) in DCD Tier 2 Rev2 will be changed to "Table 2.3.4-3 Combination of Sources and Receptors for Rod EjectionAccident Analysis (Sheet 9 of 11)"

In addition, the notation of inleak receptors, "TSC HVAC intake", in Table 2.3.4-6 (Sheet 3 of 3)is incorrect. That notation should be changed to "Auxiliary building HVAC intake" as shown inTable 2.3.4-6 (Sheet 3 of 3) of Appendix 2 attached at the end of the responses, because thenotation of the inleak receptor at the other accidents is "Auxiliary building HVAC intake".However, the location of TSC HVAC intake is the same as the location of Auxiliary buildingHVAC intake.Moreover, the notation of the source location 3 in the same Table 2.3.4-6 (Sheet 3 of 3) is notalso incorrect. Because we take the shortest distance between the source and receptor, thesource and receptor locations should be chosen to the location of the same direction as eachother.Table 2.3.4-3 (Sheet 9 of 11) and Table 2.3.4-6 (Sheet 3 of 3) will be changed as shown in thecorresponding Tables of Appendix 2 attached at the end of the responses.

d. It is an editorial mistake. The lateral and vertical diffusion coefficients for the ground levelcontainment release point to the north and south TSC HVAC intakes and to the north andsouth auxiliary building HVAC intakes should be 7.98 meters and 5.03 meters as same asTable 2.3.4-6 (Sheet 3 of 3), respectively. There is no impact on the x/Q because the correctvalues as the lateral and vertical diffusion coefficients were already used to calculate the x/QThe Table 2.3.4-3 (Sheet 9 of 11) in DCD Tier 2 Rev 2 will be changed as shown in Table2.3.4-3 (Sheet 9 of 11) attached at the end of the responses.

e. It is an editorial mistake. The source to receptor horizontal distance between the west steamrelief valve and the south TSC HVAC intake in Table 2.3.4-1 (Sheet 11 of 12) should be 62meters as shown in Table 2.3.4-2 (Sheet 7 of 8) and Table 2.3.4-3 (Sheet 10 of 11). There isno impact on the x/Q because the correct value as the source to receptor horizontal distancewas already used to calculate the x/Q.

In addition, there is another editorial mistake. In Table 2.3.4-1 (Sheet 2 of 12), the verticaldistance "-2.7" of the receptor of Reactor building door should be changed to be "-3", becauseother vertical distances are rounded off to describe.

Therefore, Table 2.3.4-1 (Sheet 11 of 12) and Table 2.3.4-1 (Sheet 2 of 12) in DCD Tier 2Rev.2 will be changed as shown in the corresondings Tables of Appendix 2 attached at the endof the response.

02.03.04-8

f. We agree with what you pointed out. Both the footnote 6 of Tables 2.3.4-1 through 2.3.4-7 andthe section 2.3.4 in DCD Tier 2 Rev 2 are the explanation of the process to derive theUS-APWR MCR and TSC X/Q values. Therefore the footnotes 6 Table 2.3.4-1 through 2.3.4-7in DCD Tier 2 Rev 2 will be changed as follows.

"(6) - These x/Q values are for US-APWR DCD Chapterl5.The xQ valu"'e of MCR can't be directly calculated by ARCON96 itself becwase there is; no

Site specific meteorological data in the stage of the DCD. Therefore, the diffusionQ equationsdesri•bed in ARGON96 (e.g. Reision , to NUREG 6331) are used fr calc-ulating the x#Qvaluess of MCAR, together wiVth the me-teorological conRdition bAMe on G 1.194 (e.g., Fstabilit' with Ywin spesof 1.0 m) and multiplicr. According to the setting method of thes-e#Q values, the closear the d-ist-Re the more c•GnReative it be••;.es. It is Rnt used theARC•"•96l d irectly in DrD.

- For each sources, the x/Q values for inleakage and intake are set as those of the path withthe shortest straight distances, respectively."

Impact on DCDAccording to the answers for the above questions a to f, the DCD will be changed to incorporatethe following:- Change the 96-720 hr x/Q values of MCR for the following tables:

- DCD Tier 1 Rev 2, Table 2.1-1 DCD (sheet 3 of 7) through Table 2.1-1 (sheet 6 of 7)(See on pages 02.03.04-11 through 02.03.04-14)

- DCD Tier 2 Rev 2, Table 2.0-1 (sheet 2 of 8) through Table 2.0-1 (sheet 6 of 8)(See on pages 02.03.04-16 through 02.03.04-20)

- DCD Tier 2 Rev 2, Table 2.3.4-1 through 2.3.4-7(See on pages 02.03.04-23 through 02.03.04-68)

- DCD Tier 2 Rev 2, Table 15A-1 8 through 15A-24.(See on pages 02.03.04-70 through 02.03.04-76)

- Change the expression "Table 2.3-1 to 2.3-4" in the last sentence of DCD Tier 2, section 2.3.4to the correct expression "Table 2.3.4-1 through 2.3.4-7".

- Change the DCD Tier 2, Table 2.3.4-3 (Sheet 9 of 11) and Table 2.3.4-6 (Sheet 3 of 3).(See on pages 2.03.04-51 and 02.03.04-65)

- Change the DCD Tier 2, Table 2.3.4-1 (sheet 11 of 12) to correct the source to receptorhorizontal distance between the west steam relief valve and the south TSC HVAC intake.

(See on page 02.03.04-32)- Change the footnotes 6 of Table 2.3.4-1 in DCD Tier 2 to delete the unnecessary information.

(See on page 02.03.04-69)- Dose calculation will be changed in DCD Chapter 15 to confirm a satisfaction of the criteria,

due to the change of 97-720 hr x/Q values.

Impact on COLAFor the question a, there is some impact for the COL applicant who has the site specific 96-720hrx/Q values between the present x/Q values of DCD Rev 2 and the changed x/Q values in additionto the site specific x/Q values of other time intervals less than the present x/Q values of DCD Rev2.They do not need to assess the dose calculation any more. Otherwise, there is no impact onCOLA.For other questions except a, there is no impact.
