Serial No.05-601 Docket Nos. 50-280, 281 ATTACHMENT 1 Discussion of Change Virginia Electric and Power Company (Dominion)

Surry Power Station Units 1 and 2

DISCUSSION OF CHANGE Introduction Pursuant to 1 OCFR50.90, Virginia Electric and Power Company (Dominion) requests a change to the Technical Specifications for Surry Power Station Units 1 and 2. The proposed change redefines the exclusion area boundary (EAB) as the site boundary in Technical Specification 5.1, Site. This redefined EAB will significantly reduce the design basis accident Atmospheric Dispersion Factor (WQ). Reducing the WQ will, in turn, reduce the calculated EAB dose consequences for the UFSAR Chapter 14 accidents in future reanalyses.

The proposed change has been reviewed with respect to 10CFR50.92, and it has been determined that no significant hazards consideration exists. In addition, it has been determined that the change qualifies for categorical exclusion from an environmental assessment as set forth in 1 OCFR51.22(~)(9); therefore, no environmental impact statement or environmental assessment is needed in connection with the approval of the proposed change. This proposed change to Technical Specification 5.1 has no adverse safety impact and will result in an increase in margin to the dose consequence limits for future accident reanalyses.

Backaround Information/Licensina Basis Dominion described the restricted area and the EAB in Preliminary Safety Analysis Report Amendment 22 of the Surry license application (Reference 1). The restricted area was described as the area enclosed by the site boundary. Dominion owns and controls access to the restricted area, exposure of individuals in this area is within the limits established in 10CFR20, and the boundary is clearly posted and monitored to ensure that unauthorized personnel will not transgress the boundary. In Figure S2.1-1 of Reference 1, the property line defines the restricted area thus establishing the site boundary as being equivalent to the property line. Reference 1 also describes the EAB as bounded by a 1650 ft. radius circle centered at the reactor containment building No. 1. This reference also states that this circle size was determined by the shortest distance to the site boundary and is sufficient, in conjunction with the plant design, to ensure that the dose limitations of 10CFR100 are met. This EAB definition was also used in the original Surry Technical Specifications dated March 17, 1972.

Currently, UFSAR Section 2.1.2.1 and Technical Specification 5.1 indicate that the minimum distance from a reactor centerline to the site EAB, as defined in IOCFR100, is 1650 ft. The UFSAR indicates that this distance is based on the distance from the Unit 1 containment centerline to the site boundary to the north, which is sufficient, in conjunction with the plant design, to ensure that the dose limitations of 1 OCFR50.67 are met.

Page 1 of 32

Based on the Technical Specification 5.1 minimum distance to the EAB, 1650 ft. was the distance used to calculate the Atmospheric Dispersion Factor (WQ) of 4.61 E-03 sec/m3 that was used in evaluating dose consequences at the EAB in the Surry Alternative Source Term (AST) license amendment request (References 2 - 9).

This X/Q was based on the Regulatory Guide 1.145 methodology using the PAVAN code with meteorological data from 1994 - 1998. Use of the 4.61 E-03 sec/m3 EAB WQ resulted in a LOCA EAB dose consequence of 24.01 Rem total effective dose equivalent (TEDE) versus a limit of 25 Rem TEDE and a Fuel Handling Accident (FHA)

EAB dose consequence of 6.27 Rem TEDE versus a limit of 6.3 Rem TEDE.

Reference 10 documents NRC approval of the Surry AST design basis, including the EAB WQ.

Redefinition of the EAB as the Site Boundary 10CFR100 includes no requirement for the EAB to be a circle, but does require the licensee to have authority to determine all activities including exclusion or removal of personnel and property from the area. Surry Power Station controls access to all areas within the site boundary.

Distances from the various release points on the site to the site boundary in the sixteen wind sectors that are used in the PAVAN calculation of WQ values vary considerably.

In general, a shorter distance between the source release point and the receptor results in a higher WQ.

For future dose analyses that may be accommodated under 10CFR50.59, it is proposed that the source-to-receptor distances in Table 1 be used to define the EAB by wind sector, which will result in the lower EAB WQ values listed in Table 2. The distance values in Table 1 are the minimum distances from the potential source release points for the LOCA and FHA to the site boundary in each wind sector.

Figure 1 is the site map that was used to determine the minimum distances from the potential source release points to the closest point on the site boundary within each wind sector. Figure 1 also shows the wind sector definition lines that were used to determine the sector dependent distances to the site boundary from the centerline of the Unit 1 Containment. Similarly, the wind sector definition lines were centered over the approximate location of each of the remaining source points in Table 1 in order to determine the minimum sector dependent distances to the site boundary from each source point.

Page 2 of 32

Table 1 : Surry EAB Source to Receptor Distance* Table with Sectors Defined with Respect to Each Source Location These distances are approximations, based on a computer-aided design (CAD) drawing. The distance of 1623 ft used in the N and NNE sectors is bounding and represents a best approximation for the defined minimum distance in Technical Specification 5.1 of 1650 ft.

These new EAB distances from Table 1 were used to modify the PAVAN input decks submitted for the AST amendment in Reference 6. Table 2 contains the results of PAVAN runs completed using the 5 sets of source-to-receptor distances from Table 1 and joint frequency distribution (JFD) tables based on meteorological data from 1994-1998. Tables 3 and 4 contain the JFDs and PAVAN input decks, respectively, that were used in the calculation of new WQ values for the EAB. The JFDs in Table 3 are identical to the JFDs for the 1994 - 1998 meteorological data previously submitted for the AST amendment (Attachment 2 to Reference 6). The PAVAN input decks in Table 4 have been revised from those used with the AST amendment to reflect the distances of Table 1. Table 5 contains the PAVAN output that results from the execution of the Table 4 input.

Page 3 of 32

Based on Regulatory Guide 1.145, the WQ value used in an accident analysis should be the limiting 0.5% sector-dependent WQ or the 5% overall site WQ values, whichever is higher.

The PAVAN results in Table 2 are the limiting 0-2 hour 0.5%

sector-dependent X/Q values, which were higher than the 5% overall site WQ. The worst-case 0-2 hour WQ (1.79E-03) at the redefined EAB occurred in the north direction as a result of release from the Unit 1 Containment.

Downwind Receptor Direction/Sector Source Location Unit 1 Containment EAB N1348.75-11.25 Downwind 0-2 hr Distance (m) (sec/m3) 495 1.79E-03 lunit 2 Containment I EAB I N/348.75-11.25 I 515 I 1.67E-031 EAB EAB West Auxiliary Building Louvers East Auxiliary Building Louvers (Ventilation Vent No. 2 I EAB I N/348.75-11.25 I 517 I 1.66E-031 N/348.75-11.25 523 1.63E-03 N/348.75-11.25 530 1.59E-03 Not shown in Tables 1 and 2 are source locations and WQ values for the steam generator power operated relief valves (PORVs) and safety valves. These source release locations would be used for the Steam Generator Tube Rupture, Main Steam Line Break, and Locked Rotor Accident. As discussed above, the limiting EAB WQ value among the 5 sources analyzed is the maximum 0.5% sector-dependent WQ in the north direction from the Unit 1 containment. The occurrence of the maximum 0.5%

sector-dependent WQ value in the north direction is primarily due to the relatively short source-to-receptor distance.

Figure 2 is a simplified site plan that was originally included in Reference 8, which was updated to include the steam generator PORVs and safety valves. As shown on Figure 2, the steam generator PORVs and safety valves are located against the southern side of the Unit 1 and Unit 2 containments. Based on inspection of the site geometry shown in Figures 1 and 2 and the results of Table 5 (PAVAN output), atmospheric dispersion from the PORVs and safety valves to the site boundary would be bounded by the Unit 1 Containment source location. Hence, the value 1.79E-03 sec/m3 would be appropriate to use as an EAB WQ for all accidents that have source locations that are bounded by the dispersion from the Unit 1 Containment.

It is intended that the highest valued 0-2 hour WQ in Table 2 (1.79E-03 sec/m3) will be used in future EAB dose assessments as an approved change to an element of a methodology.

Prior NRC review and approval of this change in the EAB X/Q is required, in accordance with 10CFR50.59, because the new value will result in a Page 4 of 32

significant increase in margin to the 10CFR50.67 offsite dose limit by changing an element of the methodology. The dose consequence accident analyses were not submitted with this change because the EAB results listed in the UFSAR are conservative with respect to consequences that would be calculated using this new EAB WQ.

Description of Proposed TS Chanqe Details of the specific revisions are provided in the following paragraphs.

The last two sentences of Technical Specification 5.1 currently state:

The minimum distance from a reactor centerline to the site exclusion boundary as defined in 10CFRl00 is 1,650 ft. This is the distance for Unit 1, which is controlling.

A map of the site is shown in TS Figure 5.1 - 1.

The last two sentences of Technical Specification 5.1 are revised as follows:

The site exclusion area boundary is defined by the site boundary line shown on the site map in TS Figure 5.1-1. The minimum distance from a reactor centerline to the site exclusion area boundary as defined in 10CFR100 is 1,650 ft.

This is the distance for Unit 1, which is controlling.

No Siqnificant Hazards Consideration The proposed change redefines the exclusion area boundary (EAB) as the site boundary. This redefined EAB will significantly reduce the design basis accident (DBA)

Atmospheric Dispersion Factor (WQ). Reducing the X/Q will, in turn, reduce the calculated EAB dose consequences for the UFSAR Chapter 14 accidents in future reanalyses. The proposed change does not involve a significant hazards consideration because operation of Surry Units 1 and 2 in accordance with this change would not:

1. Involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed redefinition of the EAB will significantly reduce the design basis accident WQ, which will result in an increase in margin to the dose consequence limits for future accident analyses. The dose consequence accident analyses were not reanalyzed with this change because the EAB results currently documented in the UFSAR are conservative with respect to consequences that would be calculated using this redefined EAB. The EAB redefinition is not an initiator of any accident previously evaluated and has no impact on radiation levels, airborne activity, DBA source terms, or releases. Therefore, the proposed change does not involve a Page 5 of 32

2.

3.

significant increase in either the probability or consequences of an accident previously evaluated.

Create the possibilitv of a new or different kind of accident from anv accident previously identified.

The proposed change involves no physical changes to the plant, nor is there any impact on the design or operation of the plant. There is also no impact on any equipment relied upon to mitigate an accident. Therefore, the proposed change does not introduce any new failures that could create the possibility of a new or different kind of accident from any accident previously identified.

Involve a siqnificant reduction in a marqin of safetv.

The proposed change does not alter the condition or performance of equipment or systems used in accident mitigation or assumed in any accident analysis. The EAB redefinition has no impact on radiation levels, airborne activity, DBA source terms, or releases. Therefore, this proposed change does not involve a significant reduction in the margin of safety.

However, the proposed redefinition of the EAB will significantly reduce the design basis accident WQ, which will result in an increase in margin to the dose consequence limits for future accident analyses.

Environmental Assessment This amendment request meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(~)(9) as follows:

(i)

The amendment involves no significant hazards consideration.

As described above, the proposed change to Technical Specification 5.1 to redefine the EAB does not involve a significant hazards consideration.

There is no significant change in the types or significant increase in the amounts of any effluents that may be released offsite.

(ii)

The proposed redefinition of the EAB does not involve the installation of any new equipment or the modification of any equipment that may affect the types or amounts of effluents that may be released offsite. Therefore, there is no significant change in the types or significant increase in the amounts of any effluents that may be released offsite.

(iii)

There is no significant increase in individual or cumulative occupational radiation exposure.

The proposed redefinition of the EAB does not involve plant physical changes that affect radiation exposure. Radiation levels, airborne activity, design basis accident Page 6 of 32

sources terms, and releases are not impacted by the proposed change. Therefore, there is no significant increase in individual or cumulative occupational radiation exposure.

Based on the above assessment, Dominion concludes that the proposed change meets the criteria specified in 10 CFR 51.22 for a categorical exclusion from the requirements of 10 CFR 51.22 relative to requiring a specific environmental assessment or impact statement by the Commission.

Changing the EAB boundary so that it is equivalent to the site boundary will not impact radiation levels, airborne activity, DBA source terms, or releases. The effectiveness of the Emergency Plan is not affected by changing the EAB definition from 1650 ft to being equivalent to the site boundary. 10CFR100 requires that the licensee have authority to determine all activities including exclusion or removal of personnel and property from the area and limit dose to members of the public. The redefined EAB meets these regulatory requirements.

Additionally, by redefining the EAB as the site boundary, the proposed changes to Technical Specification 5.1 would allow for a significant reduction of the EAB WQ.

Reducing the EAB WQ will, in turn, reduce the calculated EAB dose consequences for Chapter 14 accidents in future reanalyses.

This proposed change to Technical Specification 5.1 has no adverse safety impact and will result in an increase in margin to the dose consequence limits for future accident reanalyses.
