( )' The following sections update information presented in the

. Construction Permit Stage Environmental Report (CPSER) sections 2.1 and 2.2.

2.1.1.1 Specification of Location The 3169-acre site is located in the eastern sector of Burke County, Georgia, on the Savannah River at river mile 151, approximately 23 river miles upstream from the intersection of the Savannah River and U.S. Highway 301, as shown in figure 2.1-1.

[

2.1-1

VEGP-OLSER-2 The location and orientation of the principal plant structures within the site area are shown in figure 2.1-3. Within the site boundary, there is no prime, unique, or statewide important agricultural land. gg 2.1.1.3 Boundaries for Establishing Effluent Release Limits The property lines as shown in figure 2.1-2 are the boundaries for determining effluent release limits. Effluent releases will not exceed the limits of 10 CFR 20.106 at the boundary.

g The reference point used for determining the minimum distance to the exclusion boundary is the Unit 1 plant vent. The 1 shortest distance between the Unit 1 plant vent and the exclusion area boundary is 3700 ft.

2.1.2 POPULATION DISTRIBUTION 2.1.2.1 Population within 10 Miles Figure 2.1.3-1 of the VEGP Final Safety Analysis Report (FSAR) identifies places of significant population groupings such as cities and towns and shows their position within the grid constructed by drawing concentric rings at 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10-mile radii with the VEGP site at the center point. The concentric circles are further divided by 16 compass points thus transforming the circles into 22 1/2 sectors. Each sector therefore is composed of individual segments formed by the concentric rings divided by the 16 compass points. Tables 2.1-1, 2.1-2, and 2.1-3 lists the 1980 population data on which the 5- to 500-mile population projections are based. The population within 5 miles of the VEGP site was surveyed door to door on June 17, 1980, and updated in March 1982. Tables 2.1.3-1 through 2.1.3-16 of the FSAR provide the projected population for the first year (1987), midpoint (2007), and end point (2028) of the VEGP ll operating life for each segment. Table 2.1-4 provides totals i for each sector, and table 2.1-5 provides totals for each annular ring. The methodology for projecting and disaggregating the population is discussed in appendix 2A of the FSAR.

f 2.1.2.2 Population between 10 and 500 Miles Figure 2.1.3-2 of the FSAR displays the grid pattern used in the population disaggregation between 10 and 50 miles.

2 .1'. 2 . 3 Transient Population Data on transient population is provided in tables 2.1-26 l1 through 2.1-42. Land uses which draw nonresidents to within 10 i f(N J3,)

miles of the operating units include employment at the plant itself, employment-at the Savannah River Plant in South Carolina, traffic'on State Route 125 in South Carolina, and *

-recreational activities on the Savannah River. These uses are

.not subjact to; seasonal variations, but some variance on a j ' daily basis between weekday and weekend totals is expected.

For-this reason, tables are provided for both weekday and t

weekend day cases. Other-than this-weekday / weekend difference, activities within the 10-mile radius are not expected to result in any significant variance'in transient population on a day to ~

day or seasonal' basis. On a daily basis, population fluctuations are insignificant, making it difficult to F distinguishLand calculate peak or average population.

'()~ Employment at the VEGP in 1987 will consist of operational

-personnel for Unit 1,-security personnel, and construction ,

workers who wi11 be completing-Unit 2. Some operational,

, security,'and maintenance personnel will be at the plant site cn1 weekend l shifts. The majority of operational and

^f construction workers will work in a Monday through Friday day schedule. Most permanent plant workers are expected to live foutside the 10-mile radius in the Waynesboro and South Augusta  ;

areas. Some~ construction. workers will live within the 10-mile radius during the week, but most will return to their permanent residences:outside the 50-mile radius on weekends. By 2007, only operational and security personnel will be employed.

t' VEGP-OLSER-2 lh Savannah River Plant employees working at facilities within 10-miles of the unit are included in the tables. Most of these employees work on a Monday through Friday schedule. Only a very slight increase in the number of employees at these facilities is expected in future years. The facilities have ll changed little since they were built in the 1950s. The majority of Savannah River Plant employees live in the Aiken-Augusta corridor.

Transient highway traffic within the 10-mile radius is limited to State Route 125 in South Carolina which pasces through the llh Savannah River Plant. This highway is used by some through traffic between Augusta and the coastal areas of Savannah or Charleston. Access to the Savannah River Plant reservation is

'tur time-stamped travel pass so that records of the average number of vehicles on weekdays and weekend days are available.

Employees also use this route. Estimates were made to eliminate employees with work destinations within the 10-mile radius since they have been counted in the Savannah River Plant employee figures. Georgia State Route 23 is within the 10-mile radius. It is used almost exclusively by area residents and may be used by some plant employees. Virtually no transient traffic is expected. Paragraph 2.1.3.3 of the FSAR describes transient population within the VEGP 50-mile radius. g 2.1.2.4 Jurisdictional Population Five counties are bisected by the 10-mile radius of the VEGP.

All of the plant site is situated in Burke County, Georgia.

However, Burke County's jurisdiction primarily includes the sectors from the west-northwest to the southeast. The town of Girard is 7.5 miles south-southeast. Richmond County, Georgia, l1 lies 5 miles west-northwest and northwest from the plant site.

Three miles north of the site boundary is Aiken County, South Carolina. Barnwell County, South Carolina, lies 1/2 mile to the northeast and east-northeast. A small portion of the area within the 10-mile radius includes Allendale County, South Carolina, 8 miles east of the plant site. Tables 2.1-43 and l1 2.1-44 exhibit jurisdictional population and location, I respectively.

2.1.2.5 Methodology for Population Estimates and Projections Appendix 2A of the FSAR provides part of the information required by the draft guidelines for the OLSER. -The remainder of the information can be found in paragraph 6.1.4.2.

VEGP-OLSER-2 2.1.3 USE OF ADJACENT LANDS AND WATERS a The VEGP site is located on the southwest side of the Savannah I River about 23 river miles upstream from the intersection of

\")- the Scvannah River and U.S. Highway 301. The property is located in the eastern sector of Burke ,ounty, Georgia, across the Savannah River from Barnwell County, South Carolina. This location is approni=ately 15 air miles east-northeast of Waynesboro, Georgia, and 26 air miles south-southeast of

.( ) Augusta, Georgia. The VEGP site, which is wholly owned by Georgia Power Company (GPC), will occupy approximately 3169.1 acres as follows:

Facilit1 Acres Site acreage not related 1777.9 to construction Plant Wilson 37.7 Outside fence 519.6 (cleared area)

Inside fence 579.4 West gate 10.1 Transmission lines 136.5 (onsite)

/~N Roads 69.4

(-) Railroad 18.8 (onsite)

Pond (south) 8.5 Pond (west) 10.1 Visitor's center 1.1 Total 3169.1 The layout of these items within the site is given in figure 2.1-2.

Due to the remoteness of the VEGP site property from heavily populated areas, there are few human activities within the 5-mile radius of the plant site. A survey by the Central rg Savannah Area Planning and Development Commission'" shows no q) public or private schools, hospitals, commercial areas, industrial plants, settlements, parks, recreational areas, or valued historic, scenic, or cultural areas within the Georgia portion of the 5-mile radius from VEGP. There will be a i Georgia Power Company employees recreation area located approximately 2 miles southwest from the plant site. Refer to

(^)g

(, paragraph 8.1.2.4 for more specific information. The South Carolina portion of the area described by this 5-mile radius falls wholly within the Savannah River Plant site, which is a highly restricted area, thus excluding all public and private activities save those associated with the plant. Two Savannah r River Plant industrial sites are located within the 5-mile

(_ radius as given on figure 2.1-5, i.e., the heavy water production facility and the CMX-TNX facility. Figure 2.1-6 shows the site boundary, water bodies, and transportation lines within 5 miles of the site.

2.1-5 Amend. 1 2/84

VEGP-OLSER-2 lll The greatest single land use present and projected within the 5-mile radius area is silvicultural. The remaining lands are either swamps or agricultural areas. The current population within the 5-mile radius is approximately 1100. The residences in this radius are essentially temporary ones serving VEGP construction workers. They consist of mobile home, camper, e.nd duplex units. There are no permanent residential areas as such, though isolated residences are located in the 5-mile radius. Those near the plant site are discussed in paragraphs 2.1.3.1 and 2.1.3.2.

Lands adjacent to the GPC property boundary are generally large tracts, many of which are used as timberlands. The property lines of those adjacent and abutting properties are shown in

' figure 2.1-7. -

2.1.3.1 Residences, Meal Animals, Milk-Producing Cvws/ Goats, and Vegetable Gardens within 5 Miles of the VEGP Site The area surrounding the VEGP site is surveyed periodically for a radius of 5 miles to locate and identify the nearest residence, meat animal, milk-producing animal (goat or cow),

and vegetable garden of 500 ft2 or greater in each of the 16 sectors defined by a 22 1/2 arc around the radius. This data, along with the distance to the nearest site boundary, are found 1 in table 5.2-1. Several observations can be made from these data. First, there were no milk-producing animals identified in any of the 16 sectors. Second, all those sectors which extend into the Savannah River Plant property do not contain items in any of the listed categories. The residence listed nearest the plant site (west-southwest sector) is a trailer park housing predominantly construction-related GPC or l1 contractor employees.

2.1.3.2 Land Use within a 5-Mile Radius The remoteness of the VEGP site ensures few human activities within the 5-mile radius. There are no zoning ordinances existing for this area, nor are there any local plans to restrict development to limit population encroachment. As previously stated, there are no dairies, wildlife preserves, or sanctuaries in the area. The only industrial activity is that associated with the Savannah River Plant facility as previously described. The rural, small farm nature of this area blurs the distinctions to be made between many of the standard land use classifications. Any land may be used alternately for crops, pastures, hunting, or recreation with residences scattered sparsely throughout. None of these uses occurs on a large 2.1-6 Amend. 1 2/84

VEGP-OLSER-2 U(~N .

scale. The clearest distinction.to be made on land use is between open and wooded lands. Open lands are used as cropland, primarily since no livestock or dairy operations t' exist in the area. Estimated crop types and yields for the

\s)' area are given in paragraph 2.1.3.3. The wooded, largely silvicultural areas would more likely be used as hunting areas, though no hunting lodges or camps exist in the area. The hunting yields for Burke County as a whole are among the lowest in the state, as discussed in paragraph 2.1.3.3 of the FSAR.

lk/')

Hunting activities are, therefore, very limited. Figure 2.1-8 displays those areas which are wooded and those areas which are open. The residences in the area have been inventoried and are shown in figure 2.1-6.

2.1.3.3 Agricultural Activity The annual meat, milk, and truck farming production within a 50-mile radius from the proposed reactor is shown in table 2.1-45. The table shows the annual meat production by type

.(cattle and hogs), milk production, and truck farming at l1 successively greater 10-mile intervals from the reactor.

f)

Tu) Unless otherwise noted, the data in these tables are taken from 1979 crop year statistics published by the Georgia Crop Reporting Service and the South Carolina Crop and Livestock Reporting Service. These data compiled and presented for each segment in the tables have been disaggregated from county statistics as follows.

For each of the 16 sectors of the five 10-mile intervals, the sector was composed of parts of one or more counties. For each segment, the individual county portions falling in each segmant were measured using a grid measurement system. Next, for each county portion of a segment, the percentage of farmland in the portion was determined. This was done using a Landsat

[)

satellite photograph of the area which categorizes land type into nine categories, including cleared farmland. Estimates of the amount of farmland in each county portion were obtained using a grid estimation technique. The amount of farmland in each county portion within a given segment was then expressed s as a percentage of the total farmland in the county by dividing the farmland area in a given segment by the total farmland in

( -) that county. These percentages were then used to assign meat, milk, and truck crop production figures to the various counties. For example, segment SE-20 is composed of parts of two counties in Georgia, Burke and Screven. For that segment, 0.5 percent of the farmland in Burke County and 10.4 percent of

(-s) the farmland in Screven County fall in this segment. Thus, for a given commodity such as truck crops, 0.5 percent of the total 2.1-7 Amend. 1 2/84

truck crops produced in Burke County and 10.4 percent of the total truck crops produced in Screven County are assigned to segment SE-20. The total production of truck crops for that segment, therefore, is 1015.3 kg, the value given in table 2.1-45. g Table 2.1-46 shows annual agricultural crop production for the 1

50-mile radius around the proposed reactor. The table shows total annual production quantity (kg) by crop type. Tchlo 2.1-47 shows the average annual yield for each of these crops in the same area. These data are based on statistics for 1979 g from the same sources as the meat, milk, and poultry data above.

'The vast majority of the cattle operations in the 50-mile area around the plant site consists of brood cows and calves and stockherd calves. These cattle graze year round. In the summer months (March through October),. they graze primarily on permanent pasture land planted in coastal Bermuda grass, fescue grass, or other native grasses. In the winter months (November through February), they graze primarily on field residues of harvested crops such as corn, grain sorghum, and peanuts or on winter forage crops, primarily rye, and to a lesser extent, barley or wheat. Hay, primarily from coastal Bermuda grass, is used as a supplemen*ary feed to foraged feed, primarily in the winter months. Silage, primarily corn and grass, is also used as a supplementary feed but to a lesser extent.

2.1.3.4 Recreational Fishing Marine fishing data are not applicable because the proposed reactor site is,not within 50 miles of the Atlantic Coast. The site is situated on the Savannah River (river mile 151) potentially impacting both commercial and recreational fishing. Data on recreational fishing success in the Savannah River from the river mile O to mile 187.2 have been obtained from creel and roving surveys conducted by the Georgia lll Department of Natural Resources (DNR). Table 2.1-48 presents l1 the annual estimate of total number, average weight, and kg/ha by species from river mile O to mile 21.6 for the period December 29, 1979 to December 26, 1980. The total area covered by this survey was approximately 2535.2 ha. The recreational harvest for this section of the Savannah River was estimated to lh be 6.4 kg/ha. Table 2.1-49 shows the annual estimate of total l1 number, average weight, and kg/ha by species from river mile 21.6 to mile 187.2 for the period December 29, 1979 to December O

2.1.3.5 Commercial Fishing Commercial fishing data for the entire Savannah River is not available at this time from the Georgia DNR. Table 2.1-50 l1 D

('wl- presents 5 years of data on weight and cash value of commercial shad from the lower Savannah River. The 5-year mean weight of shad was 37,183.6. kg with a mean value of $64,153.

.2.1.3.6 Hunting Deer hunting does occur within the 50-mile radius. Both hunting pressure and hunting success are very low, however.

The State Game and Fish Commission's estimated annual harvest of deer ranges from 6280 to 18,840 deer. Estimated annual number of licensed hunters is 2500 to 5000. Other major species hunted include quail, rabbit, dove, turkey, woodcock,

(~3 squirrel, duck, fox, and raccoon. No data are available on the

(_) success rate fer hunting of these species on a regional or local level.

2.1.3.7 Public Accessibility The remote, rural nature of the VEGP site and property has ensured minimal disruption to local land uses. All cooling water conveyance structures are contained on GPC property, and the pcint where these structures, both intake and outfall, join the Savannah River is not frequented by recreational users such as fishermen. (Recreational hunting and fishing activities are discussed in previous sections.) A single railroad spur has fs

\')

v been constructed from the main line at Waynesboro to bring construction materials to the site and will be used for supplies in the future. The route for this spur did not interfere with any existing land uses. One road, i.e., River Road, has been diverted to skirt the GPC property. Old River r- Road, prior to GPC's activity, was a soil surfaced road. New River Road, which borders the GPC property, is paved. Thus,

(' 3j even the minimal increase to the distance traveled to avoid GPC property is compensated for by the higher quality of the roadway. No additional offsite access or other activities which could interfere with existing or projected land uses are contemplated at this time.

2.1.3.8.1.1 Surface Water. The VEGP site is bordered on the east side by the Savannah River and on the south side by Beaverdam Creek. The discharge structure for the plant is directed into the Savannah River at about river mile 151. All l1 ~h overland flows would drain into either the Savannah River or Beaverdam Creek, which also discharges into the Savannah River immediately. The area of possible surface water contamination is, therefore, limited to the Savannah River downstream of the plant discharge (figure 2.1-9).

2.1.3.8.1.2 Groundwater. Additional groundwater information from that presented in the CPSER subsections 2.5.4 and 5.5.3 is summarized in FSAR subsection 2.4.12 and includes more recent water level data. Two distinct aquifers underly the VEGP site. Both have been studied and monitored by GPC extensively over the past 10 years. The shallow or unconfined groundwater aquifer is replenished by rainfall percolating lll through the porous overlaying sands. The presence of porous surface sands and the moderate topographic relief in the site area indicate that there is no significant storm runoff; hence, virtually all precipitation infiltrates the ground. Lateral recharge from adjacent areas is insignificant because the plant area is situated on an interfluvial high; i.e., it is isolated by drainage channe'.s which have down cut to or near the marl aquilude and act 5 interceptor drains to potential recharge sources moving laterally toward the interfluvial. Groundwater present in the sands beneath the VEGP site eventually drains to the Savannah River through springs along the bluff. Figure 2.1-10 shows the direction of flow and the probable discharge point of contaminants percolating into the artesian aquifer beneath the plant site.

The second aquifer lies beneath a relatively impermeable aquiclude and is unlikely to be contaminated by spillage on the plant site. Should this occur, however, the flow of this aquifer is also towards the Savannah River, as indicated in figure 2.1-10. Exploratory holes drilled adjacent to the river indicate the aquiclude has been breached by the river allowing groundwater from the underlying aquifer to discharge to the river. Migration through the groundwater table to areas across the river is, therefore, highly unlikely.

g VEGP-OLSER-2 2.1.3.8.2 Usage of Possibly Contaminated Water Supplies The Savannah River system below the VEGP site is very sparsely lll developed and, therefore, has few users. Population centers utilizing the Savannah River are not encountered until the ocean outfall of the river is approached in the area of Savannah /Chatham County (figure 2.1-9). In this area, eight withdrawals have been identified of which two serve at least some domestic users. One other withdrawal was identified in the area, i.e.,' Continental Forest, Inc.; it was determined llh that this withdrawal was from an upstream tributary to the Savannah River and, therefore, is not exposed to possible contamination.

'The two population areas which are served by withdrawals from the Savannah River are the Beaufort / Jasper County water intake which currently serves approximately 50,000 domestic users and 1 the water intake for the Cherokee Hill Water Treatment Plant which serves an effective population of 20,000 users. The Beaufort / Jasper County intake currently withdraws 5.18 million gal / day and is located at approximate river mile 39. It is projected, based on the Office of Business Economics-Economic Research Service's population projections, that by the year G 2020, the domestic withdrawal rate will be approximately 5.47 million gal / day. Cherokee Hill Water Treatment Plant's domestic withdrawal rate is currently approximately 45.07 million gal / day and is expected to increase to 59.9 million gal / day by the year 2020. It is located downstream of the Beaufort / Jasper County intake at about river mile 29.

All of the remaining withdrawals are for industrial purposes, primarily cooling water. The industrial process water used is primarily for paper processing. There are no process waters associated with foodstuffs. There are no identified groundwater users such as riverbank wells which could conceivably be contaminated by VEGP discharge. A survey O conducted by GPC found that there was no irrigation water withdrawal from the Savannah River near the plant site.

Table 2.1-51 lists the identified water users which could be l1 contaminated by VEGP discharges, including the user name, type e of water use, distance from the station in river miles and radial miles, current and projected withdrawal rates, and estimated return rates. Projections were made based on population for domestic users and the type of industrial use for other users. The various power company usages are not expected to' increase over the projectior. period. The other e industrial users are assumed to increase withdrawal rates at an average of 2 percent per year. Return .ates were calculated on 2.1-11 Amend. 1 2/84

)

the assumption that domestic, industrial process, and cooling waters were 80, 90, and 95 percent of withdrawal rates, respectively. Use of the Savannah River does not vary seasonally, nor are there significant storage ponds or flow augmentation activities. llh 2.1.3.9 Socioeconomic Conditions The socioeconomic sources '2 , ' ' identified in this subsection for Burke and Richmond Counties serve to update lh information presented in the CPSER section 2.2.

Burke County has a rural / agricultural economic base with some manufacturing. Major industrial activity in the county includes the manufacturing of draperies, clothing, lumber, fabricated metal products, and electric machinery. Table 2.1-52 shows the largest employment sectors for the county. l1 Burke County ranks as one of the largest counties east of the Mississippi River and is sparsely populated. Currently, there is no county-wide zoning in force. The Burke County public school system is consolidated county-wide with nine facilities. The Burke County cities of Waynesboro, Midville, and Sardis are served by public water and sewage systems. Fire protection in Burke County is provided by volunteers in the cities of Waynesboro, Sardis, Midville, Girard, and Alexander.

The sheriff's department provides services to the entire county, supplemented by municipal police forces of Waynesboro, Midville, and Sardis.

The economy of Richmond County is much more diversified than Burke County's, largely due to the influence of the Augusta metropolitan crea. The county's economy is based on finance, insurance, real estate, and services. Although smaller in area, Richmond County is more densely populated than Burke County. The city of Aucusta has experienced considerable commercial, institutional, and residential land development.

The Richmond County public school system is consolidated county-wide with 55 f6cilities. Most of the county's sewage and water service is provided by the city of Augusta. Fire protection in Richmond County is provided by four fire departments: the Richmond County Fire Department; the Augusta Fire department; and fire departments for the cities of

Hephzibah and Oakridge. The Augusta Police Department provides service within the city limits of Augusta, with the rest of the county being serviced by the Richmond County Sheriff's Department.

by several species but in relatively low numbers compared to the

' diatoms. This observation is in agreement with other studies done on the Savannah River phytoplankton population by the

()

Academy of Natural Sciences of Philadelphia.

2.2.2.5.2 Zooplankton

,s A study of the zooplankton community of the Savannah River near J]'

\-

the VEGP site began in January 1981 and ended in September 1981 (see section 6.1.1.2.4). The purpose of this study was to gather baceline data on species composition, density, and diversity of the zooplankton community.

'A total of 32 taxa were collected in the Savannah River between river mile 150.6 and river mile 151.2. The number of taxa collected for each major taxonomic group were: Protozoa, 7; Cnidaria, 1; Rotifera, 12; Copepoda, 3; Ostracoda, 1; Cladocera, 1; other Crustacea, 1; and miscellaneous taxa, 7. Because most identifications were made only to major taxonomic levels and many soft-bodied forms were destroyed by the formalin -- -

preservative used, the actual species variability of the zeoplankton populations were underrepresented.

Members of the phyla Protozoa comprised approximately 61 percent of the. total number of zooplankton samples taken in 1981.

Rotifera represented about 18 percent; Crustacea, 10 percent; and other miscellaneous phyla, 10 percent of the total samples taken. Keratella opp. was one of the most abundant rotifers in the studies from 1959 to 1962 conducted by the Academy of Natural Sciences of Philadelphia and in the 1981 study.

Relatively low densities of rotifers, copepods, and crustacean nauplii were also observed in both studies.

Densities of zooplankton were relatively iow in the Savannah River near the VEGP. Other studies ' " s 2" conducted on l1 bw) the Savannah River revealed low zooplankton densities. The

\- .

number of protozoan species varied greatly from that found in other studies and is probably due to differences in sampling design, methods, and level of identification.

(

w) 2.2.3 RARE AND ENDANGERED SPECIES Vertebrate species which may be found in the vicinity of the VEGP and which are listed on the Federal Endangered Species List'" ' and Georgia's Protected Species List'" are the f3 shortnose sturgeon (Acipenser brevirostrum), American

( alligator (Alligator mississippiensis), mountain lion I' ' ) (Felis concolor cougar), ivory-billed woodpecker Campephilus principalis), red-cockaded woodpecker (Picoides 2.2-11 Amend. 1 2/84 I l

__ _ _ _ _ _ _ _ _ _ _ _ _ _ - _ _ i

VEGP-OLSER-2 borealis), peregrine falcon (Falco peregrinus), and the southern bald eagle (Haliaeetus leucocechalus leucocephalus).

The shortnose sturgeon was not reported as occurring in the &

Savannah River by Dahlberg and Scott or McFarlane, W et al. '" Heidt and Gilbert"' reported its occurrence in the Savannah River, and more recent reports from South Carolina biologists'" indicate its occurrence as far upstream as river mile 134. The specimens are reported from Millett and Tillman, South Carolina. In 1979, 1980, and 1981, specimens collected numbered 10, 7, and 12, respectively. Studies by GPC have g

failed to verify the presence of either the adults or larvae of the shortnose sturgeon in the vicinity of the VEGP (D. O. Foster letter to E. G. Adensam, July 7, 1983). Specific sampling tech-niques for adult shortnose sturgeon were not used and may be the reason for their absence.

Heidt and Gilbert'" stated that the shortnose sturgeon was reported to be rare and thought to have disappeared from much of its range in the United States. It appears to be relatively common in many large rivers along the eastern coast. Studies in large rivers of the eastern United States would probably reveal additional shortnose sturgeon populations. The Georgia g Protected Species List recommends the life history and habitat W requirement of the shortnose sturgeon be researched and critical habitats be determined. Such information is not yet available for the State of Georgia.

The American alligator has been sighted on the Savannah River and in sediment retention basins 1 and 2 located on the plant site. The habitats preferred by the American alligator are swamps, lakes, sloughs, or sluggish streams. The status of the American alligator was noted in FES subsection 2.7.1.

The mountain lion has not been sighted nor have tracks been found on the plant site. The species has been reported from Columbia County, located north of Burke County, but has not been reported from Burke County. Farming and logging operations have probably led to the decline of the species, which prefers vast tracts of undisturbed land. Since much of the area eurrounding the plant site has been disturbed by farming and logging operations, it is doubtful that the species occurs in the g vicinity of the plant site. W The ivory-billed woodpecker and red-cockaded woodpecker are very habitat-specific species. The ivory-billed woodpecker requires extensive acreages of mature cypress swamp and bottomland hardwoods. This species has not been observed in Georgia in 3 over 30 years and is probably now extinct. The red-cockaded w 2.2-12

VsC?-OLSER-2

( )

-woodpecker requires overmature pine trees infected with red-heart disease. There is no suitable habitat on the site for J

either of these two species.

~O The peregrine falcon is a migratory bird in. Georgia most often observed on the coast. Because of its migratory status, the species should not be~affected by the VEGP site. There have

-been no observations of this species on the site or nearby vicinity.

.O _ The southern bald eagle requires extensive undistu re b d shoreline and large. nesting trees. Although the site or nearby vicinity offers very little stitable habitat for the species, one might occasionally fly near or across the site. There have been no observations made of the species on the bird surveys conducted by GPC-biologists.

, Plant species which may be found in Burke or surrounding Georgia counties and listed on Georgia's Protected Species List'" are nostronia (Nestronia umbellula), hooded pitcher plant (Sarracenia minor), pond bush (Litsea aestivalis), fly

_ catchers (Sarracenia' flava), parrot pitcher plant (Sarracenia psittacina), and sweet-pitcher plant

'(Sarracenia rubra).

.Nestronia is primarily found in' pine-deciduous woods in the piedmont of Georgia. The hooded pitcher. plant, fly catchers, parrot pitcher plant, and sweet pitcher plant are found in acidic soils in piney flatwoods. The pond bush is found growing

.in. swamp margins, lime sink ponds, all low, wet woodlands.

There is very little suitable habitat on the site or nearby vicinity capable of supporting any of these protected plants.

No protected plants have been located on the site during the vegetation surveys conducted by GPC biologista and foresters.

() There~are no invertebrate animals in Georgia listed on the Georgia or Federal Endangered or Threatened Species List. "'

There are no designated or proposed critical habitats for any endangered or threatened species on the plant site or nearby r- vicinity.-

2.4 HYDROLOGY

.Since the submission of the VEGP Construction Permit Stage

( '.' -Environmental Report (CPSER) and the. publication of the Nuclect Regulatory. Commission's Final Environmental Statement (FES),

additional flow and water quality data for the Savannah River and groundwater have become available. The following is a brief description of these additional studies and factors which

.have changed since the CPSER and FES.

2.4.1 SURFACE WATER ENVIRONS Since the completion of the FES, an additional upstream reservoir, Richard B. Russell, located between Clarke Hill and Hartwell raservoirs has been scheduled for completion in 1984.

The construction of this reservoir is not expected to change

-the low or average-flow characteristics at the VEGP site.

Based on data from the United States Geologic Survey gaging station at Augusta, Georgia (approximately 50 river miles

.. upstream from the VEGP site), the annual average flow of the

} Savannah ~ River is 10,300 ft'/s.

by the U.S. Corp of Engineer. dams, the minimum flow, guaranteed Due to upstream flow control to' preserve navigability, is 5,800 ft'/s with 6,300 ft'/s achieved 70 percent of the time.

-There.are_four facility s'ructures c in the flood plain associated with VEGP: the intake structure with canal; the barge unloading facility; .the site runoff flume; and site discharge pipe. These facilities have been permitted by the Corps of Engineers pursuant to section 10 of the River and Harbors ~Act and section 404 of the Clean Water Act. As part of that-process-(33 CFR 320.4 (1)), the Corps of Engineers considered Executive order 11988 relative to flood plain jn. management and the effect that these facilities would have on T ,)  : upstream and downstream users.

Detailed information on surface water-is found in section 2.4 of the Final Safety Analysis Rep' ort (FSAR). Section 2.5 of the CPSER and section 2.5 of the FES contain further information on y surface ~ water.

2.6 REGIONAL HISTORIC, ARCHAEOLOGICAL, ARCHITECTURAL, SCENIC, CULTURAL, AND NATURAL FEATURES

/m (U) 2.6.1 THE PLANT SITE Historic and archaeological features of the plant site and vicinity were addressed in section 2.3 of the Construction Permit Stage Environmental Report (CPSER). The CPSER also

() describes consultations with the state archaeologist and actions taken at that time to mitigate construction effects. There are no historic sites listed in the National Register of Historic Places or Natural Landmarks within a 5-mile radius of the

  • plant. A recent review of the National Register of Historic

' Places lists threr, additional properties in Burke County. These include the Sapp Flantation near Sardis, the John James Jones House in Waynesboro, and the Burke County Courthouse, also in Waynesboro. Since none of the properties above and none of those listed in the CPSER are in or near the VEGP site, they will not be adversely affected by plant operation. The National Register of Natural Landmarks lists 12 sites in Georgia.. None --

of these features are near the VEGP site and thus will not be

("N affected by plant operation. The Botsford Church, listed with

'\ ) the Georgia State Historical Commission (1954), is located approximately 6.7 miles west-southwest of the plant (see subsection 3.1.6) .

~During May 1983, the fossilized remains of a prehistoric whale were discovered near the west side of the VEGP intake structure. The State of Georgia Geologic Survey Branch examined the fossil and determined it to be 45 to 50 million years old.

The Georgia Geologic Survey Branch provided a list of potential candidates to receive the fossil, and at their recommendation the foenil was donated to Georgia Southern College for curation and display in the Georgi'a Southern Museum. Removal of the g3 foasil was completed in June 1983. A summary of events

() surrounding this discovery was provided to the Nuclear Regulatory Commission's staff (D. O. Foster letter to E. G. Adensam, July 7, 1983).

(} VEGP-OLSER-3 3.4 HEAT DISSIPATION SYSTEM .

The heat dissipation system serves to dissipate the excess heat f1 Nl produced by the plant to the environment. At VEGP heat dissipation occurs in two systems, the cooling towers of the i circulating water system and the nuclear service cooling water

.(NSCW) system. Figure 3.4-1 is & general flow diagram of the heat dissipation system at VEGP. Section 3.3 provides flows for the various system components. The environmental interfaces occur at the intake and discharge structures, the makeup wells,

.Os and at the cooling towers.

The cooling towers of the circulating water syster dissipate heat to the atmosphere removed from the main condensers and from the components of the turbine plant cooling water systems. The cooling towers of the NSCW system dissipates heat to the atmosphere from the nuclear plant service water system. The water needed to operate the two cooling systems is provided by the Savannah River for the circulating water system and the plant makeup wells for the NSCW system. Cooling tower blowdown and c,aer station liquid wastes are discharged to the river j through a single point discharge.

I) Since the Construction Permit Stage Environmental Report (CPSER) l was submitted, a number of changes in design affecting the heat

-dissipation system have been made, including:

A. Reduction in the number of units from four to two.

B. Change of the discharge structure from a multiport diffuser type to a single point discharge.

! C. Change of the intake structure canal design from slope l riprap to vertical sheet pile to improve erosion I control.

] ) D. -Addition of lateral escape passageways for fish escape at the intake canal entrance.

3.4-1

VEGP-OLSER-3 h general site location of the intake structure is shown in figure 2.1-2. Figure 3.4-2 shows the intake structure and canal in greater detail. The ambient river flow and water quality characteristics are discussed in section 2.4.

3.4.1.1 Intake Canal The intake canal is a 356-ft long, 140-ft wide structure with an earther. bottom at 67 ft msl and vertical steel sheet pile sides extending to 98 ft msl. Tha intake canal has a skimmer weir (el 78 ft mal) with guice vanes at the river entrance. The skimmer weir consists of both fixed and removable sections with the fixed sections having elevations below 78 ft msl. A canal weir

'is located approximately 100 ft inside the canal. Silting protection is provided by a sedimentation basin formed by the skimmer weir and the canal weir. Sediment will be dredged, and disposed of in an upland disposal site, when the depth in the basin causes excessive sedimentation in the main canal section. l1 A floating trash boom is located in front of the skimmer weir to divert large floating debris.

The component of the river velocity parallel to the canal velocity is small, thus minimizing the potential for fish llh entering the canal. In addition, a lateral passageway is provided at the canal entrance which permits fish to escape.

The flow through the canal is determined by plant operating conditions. Velocities are also dependent on the river water level. The average velocity at the river intake canal entrance ranges from 0.01 ft/s at minimum plant withdrawal rate (13,000 gpm) and a river water level of 98 ft msl (top of canal sheet piling), to 1.05 ft/s at a maximum plant withdrawal rate (72,000 gpm based on all four intake pumps operating) and a minimum river water level of 78.4 ft msl (allowing for 2 ft of riverbed degradation) at guaranteed low flow of 5800 ft 2/s. At average plant operating conditions (42,000 gpm based on two intaxe pumps operating) and annual average water level (84 ft ms1 based on annual average river flow of 10,300 ft*/s) the entrance velocity is 0.11 ft/s.

3.4.1.2 Intake structure The intake structure is a 147-ft long, 72-ft wide concrete structure with four chambers, each housing one pump, a traveling water screen, a trash rack, stop logs, and associated equipment as shown in figure 3.4-2.

())

The trash racks are fabricated from American Society of Testing Materials (ASTM) A36 structural steel shapes and bars and serve

- to filter out large pieces of debris that bypass the floating

/si/ trash boom. The trash racks are cleaned by manually raking aa required. The debris is taken to an upland disposal site. The approximate size of the trash racks is 14 ft by 14.5 ft with 1/4-in. by 4-in. bars spaced on 2-in. centers, es The stop logs, approximately 14 ft by 14.5 ft, are fabricated

(  ; from ASTM A36 structural steel shapes and plates. They serve to cut off flow from the intake canal to isolate individual chambers when a pump or traveling screen requires maintenance.

The traveling water screens are FMC type-45A water screens. The

' screens move at a vertical velocity of either 5 or 10 ft/ min.

Debris that collects on the screen face is washed by water spray into the trash channel where it is sluiced into the trash basket located in the trash basin. The trash basket is emptied periodically and the contents are carried to an upland disposal site.

~

The depth cf water varies from a minimum water level of 78.4 ft

('} m'sl at a river flow of 5800 ft'/s (allowing for 2 ft of

\_/ river 3ed degredation) to the average water level of 84 ft msl (at a river flow of 10,300 ft"/s) and a maximum expected water level of 120 ft msl (at a river flow of 400,000 ft'/s). The top deck of the intake structure is at 125 ft mel which is 5 ft above the standard project flood stage of 120 ft msl. The velocities of water through various intake structure passages for a 42,000 gpm (based on two intake pumps operating) plant operating condition are as follows:

A. Through trash racks at average annual water level -

0.33 ft/s.

B. Through trash racks at minimum water level - 0.40

[m) v ft/s.

C. Through traveling screens at average annual water level

- 0.69 ft/s.

7 's D. Through traveling screens at minimum water level - 0.82

) ft/s.

There is a potential for increased velocities, since there is the possibility of screen clogging. The maximum velocity condition will occur with a minimum water level of 78.4 ft msl

,3 (allowing for 2 ft of riverbed degredation) and the screens or

( ') ~

trash racks 44 percent clogged. This condition will cause a 5 ft differential head across the screens or trash racks and will 3.4-3

I VEGP-OLSER-3 result in velocities of 0.81 ft/s through the trash racks and 1.50 ft/s through the traveling water screens.

3.4.1.3 Makeup Pumps Four vertical pumps, rated at 22,0C0 gal / min each, are located in the river intake structure. The combined discharge of the four pumps is adequate to supply water to the two turbine plant cooling towers and radwaste discharge dilution simultaneously during extreme operation, that is, while the towers are llh operating at approximately two cycles of concentration with maximum evaporation and drift.

3.4.1.4 Intake _ Structure Design and Operation The VEGP Construction Permit contained two conditiotas relative to the intake structure design and operation. Condition E(5)(c) required that:

All the cellr> in the intake structure will normally be used during operation of the intake pumps. gg Condition E(7) required that:

Pricr to construction of the intake structure, the applicant shall submit the results of the aquatic monitoring programs and an evaluation of the environmental impact of the intake canal and intake structure which will satisfy the staff that impingement will not have a significant adverse effect on the adult population of resident and anadromous fish in the Savannah River.

Condition E(5)(c) was based on the conceptual design at the time of the CPSER and the Final Environmental Statement. This condition was to prevent localized high velocities that would occur by operating up to four pumps through only ora cell. Thus for that design, operating all cells simultaneous)y would minimize impingement. That design has been modified such that each cell operates independently and contains only one pump.

Tlis redesign (one pump / cell) will allow only one pump to be operated through each cell. Associated velocities through a particular cell will result from one pump operating and thus reduce potential impingement losses. All cells, therefore, will not necessarily be used during normal operation of the VEGP.

Georgia Power Company submitted the study required by condition E(7) on January 28, 1981 (G. F. Head letter to D. E. Eisenhut).

The study was based on the present canal and intake design 3.4-4

(} VEGP-OLSER-3 3.6 CHEMICAL AND BIOCIDE EFFLUENTS The VEGP will discharge a variety of chemical and biocide wastes to the environment during startup and operation of the plant.

(s*) All waste discharges will be in accordance with applicable state ,

and federal effluent limitations. These effluent limitations will be delineated in the National Pollution Discharge Elimination System permit to be issued by the State of Georgia.

The application for this permit was submitted to the (s) Environmental Protection Division on November 3, 1983 (T. E. ,

Byerley letter to G. B. Welsh). A copy was provided to the Nuclear Regulatory Commission (NRC) at the time of sub.r.ittal.

lf The following systems and their liquid and solid wastes are discussed in this section:

A. Circulating water system (natural draft) cooling tower blowdown, salt drift, and tower basin deposited

. solids.

B. Nuclear service cooling water tower blowdown and tower basin deposited solids.

C. Low volume wastes:

1. Steam generator' blowdown and wet layup waste.
2. Auxiliary boiler blowdown.
3. Startup and equipment cleaning wastes.
4. Water treatment plant regeneration waste water.
5. Radwaste system controlled liquid radioactive discharge.
6. Turbine building floor drains.

7-

'# 7. Miscellaneous building and area drains.

Use of chemicals and biocides at VEGP in the systems listed above is summarized in table 3.6-1. The liquid wastes listed gs above plus sanitary waste (section 3.7) will be treated and then

(_) combined prior to discharge to the Savannah River. The discharge-flows are shown in figure 3.3-1. The characteristics of the plant discharge are summarized in table 3.6-2. The treated effluent will be discharged into the Savannah River through a single discharge pipe as described in subsection 3.4.5 and will comply with the Environmental Protection Agency (EPA)

,s' 7) i effluent guideline limitations as discussed in subsection 1 5.1.1.

3.6-1 Amend. 1 2/84

VEGP-OLSER-3 llh Solid wastes discussed in this section are materials which will be deposited on the floors of the cooling tower basins, waste water retention basins, and solids emitted as salt drift from the cooling towers. The deposited solids from cooling towers and the waste water retention basins must be periodically removed and disposed of as discussed in subsection 3.6.4. Salt drift emissions are also discussed in subsection 3.6.4.

Since the Construction Permit Stage Environmental Report (CPSER) was submitted, a number of changes in design which affect chemical and biocide discharges from the plant have been made, including:

A. Decrease in plant size from four to two units.

B. Addition of a wasta water retention basin and blowdown i sump.

C. Change in plant discharge structure from a multiport diffuser to a single point discharge.

D. Changes in steam generator system chemical control (i.e., all-volatile instead of phosphate treatment and selection of ammonia from several alternatives for pH lll control).

E. Changes in the handling of laboratory, laundry, and hot shower wastes from drumming to a combination of recycling, treatment, and release as part of combined plant liquid discharge.

Design parameters and details for various systems have been modified and refined during the detailed design process. This section updates information presented in CPSER section 3.7 and provides additional information developed during the detailed design effort for the VEGP.

3.6.1 COOLING TOWER WASTES 3.6.1.1 Main Circulating Water System The natural draft cooling towers, which are a part of the cirealating water system, are duscribed in section 3.4. Cooling tower blowdown is discharged to maintain acceptable levels of total dissolved solids in the circulating water. The characteristics of the tower blowdown depend on the cycles of concentration, quality of the makeup water supply, and the chemical feeds used to control biological growth, corrosion, l1 scale, silt, and pH.

3.6-2 Amend. 1 2/84

N VEGF-CLSEP-3

{ .

As discussed in subsectic,ns 3.3.1 and 3.4.1, makeup water is supplied to the. main cooling towers from the Savannah River.

During normal operation the makeup. flow is varied to replenish

() circulating water system losses due to evaporation, drift, and blowdown. Blowdown flow is varied to maintain the circulating water cycles of concentration between two and six.

The circulating water chemical injection system provides acid and chlorine to maintain proper pH and control biological

() growth. Sulfuric acid, 66 Baume', is added to the circulating water system through metering pumps at a rate sufficient to reduce alkalinity and maintain the pH that will result in a Ry:nar Index of between 7.0 to 7.5 to balance scaling and corrosion effects. Chlorine is added to the system to control biological growth in the tower-condenser system. Chlorine is injected as a gas dissolved in water.

The river water makeup system will be continuously chlorinated at a level of 10 ppm providing a free available chlorine concentration of 1 ppm.

Chlorine is diffused into the suction of the river makeup water pumps at the river intake structure. Grab samples are taken at 0'- the discharge of the river makeup water pumps to monitor 1 chlorine concentrations.  ;

Chlorine is injected directly at the circulating water system intake structure. Grab samples will be taken from the natural draft cooling tower blowdown line to monitor chlorine concentrations.

The amount of chlorine added depends upon the rate of biological growth in the circulating water. In general, intermittent chlorination to produce approximately 0.2 mg/l free available chlorine in the circulating water is expected. During the summer, because of increased biological growth on warm days, O1l chlorine is injected from usually 1 to 3 times / day. During the l1 winter when chlorine demand is low, a single weekly injection period is required. During Corbicula spawning season (section 2.1), chlorination will be continuous up to a level of 10 mg/l providing a 1.0 mg/l free availaole chlorine. The maximum free available chlorine in the blowdown will be limited to an average of 0.2 mg/l with a maximum spike of 0.5 mg/1. Chlorination rates will vary depending on system conditions. Maximum system design chlorination rate is 10,000 lb/ day. At present, the EPA does not have an effluent limitation on total residual chloriac 1 for cooling tower blowdown. Operating experience with other cooling towers within the region have shown a total residual

.i chlorine concentration in the blowdown usually less than 0.1 mg/1. The total residual chlorine cencentrations of the cooling tower blowdown at the VEGP should be in the same range as that 3.6-3 Amend. 1 2/84

VEGP-OLSER-3 llh found at other cooling towers within the region. The system is l1 designed to ensure that the station effluent meets EPA chlorine effluent limitations (section 5.1.1).

Discharge from the two natural draft cooling towers is combined

=

in a sump, with discharge from the nuclear service cooling water towers and other station liquid wastes discharged from the waste water retention basin. The sump liquid is combined with other station effluents as discussed in subsection 3.6.3 and discharged to the Savannah River.

Suspended solids deposition in the circulating water system is controlled through the use of dispersants, as required. The dispersant is selected and used according to specific needs.

. Mud and other solids are deposited in the bottom of the cooling tower basin. These wastes are discussed in paragraph 3.6.4.1, 3.6.1.2 Nuclear Service Cooling Water (NSCW) System The VEGP utilizes one operating and one spare NSCW tower per unit as described in the Final Safety Analysis Report (FSAR) section 9.2.1. During normal operation, the blowdown flow is varied to maintain the cycles of concentration to between two lh and eight.

Acid and chlorine injection is provided to control pH and to inhibit biological growth. Sulfuric acid (66" Baume') is added as required to maintain a pH that will result in a Ry:nar index of 7.0 to 7.5 to balance scaling and corrosion effects. Tower chlorination varies usually from three times per day on warm l1 summer days to one time per week during the winter. A dispersant is applied as needed to control the suspended solids contents.

Chlorine is injected in the NSCW pump discharge. Grab samples will be taken from the blowdown line to monitor chlorine concentrations. The maximum free available chlorine concentration will be limited to an average of 0.2 ppm with a maximum spike of 0.5 ppm in the blowdown.

Chlorination rates will vary depending on system conditions.

Maximum system design chlorination rate is 2000 lb/ day. There is only a remote possibility of the NSCW system becoming i contaminated with Corbicula. That remote possibility occurs if river water makeup is provided for the NSCW system. If that occurs prolonged continuous chlorination will be employed to ensure that there is no infestation of the NSCW system by Corbicula. Total residual chlorine concentrations in the blowdown will be similar to that discussed for the main circulating water system.

VEGP-OLSER-3 Blowdown frcm the nuclear service cooling water towers is combined with other station wastes and discharged to the Savannah River as discussed in subcection 3.4.5. Solid wastes l1 l from the tower basins will be handled in the same manner as described in paragraph 3.6.1.1 for the main circulating water system cooling towers.

3.6.2 LOW VOLUME WASTE 3.6.2.1 Steam Generator Syt f3 3.6.2.1.1 Blowdown The steam generator blowdown cyctem controls the concentration  :

of chemical impurities and radioactive materials in the secondary side of the steam generators. Control of the steam generator system chemistry is based on all-volatile treatment rather than-the phosphate treatment system described in CPSER subsection 3.7.2. Hydrazine and ammonia are provided to the condensate and feedwater system for oxygen and pH control, 9 respectively.

The amount of hydrazine used during plant operation depends upon the quantity of oxygen entering the feedwater system via the condensate and/or makeup water system. Hydrazine is usually added at 3 to 5 times the dissolved oxygen concentration in the condensate. Hydrazine may be applied at a maximum flowrate of 12 gal /h using the commercially available 35 percent solution.

Ammonia is added to the steam generator feedwater during normal operation to maintain the appropriate pH usually between 9.0 and 9.5. Ammonia may be applied at a maximum flowrate of 12 gal /h using dilutions of the 29 percent commercial solution.

h Approximately 1.5 mg/l of ammonia is required in the feedwater to maintain a pH of 9.5.

Steam generator blowdown is cooled in a heat exchanger and may be directed through a backflushaole prefilter and two mixed bed demineralizers. The demineralized blowdown is normally directed h to the condenser with an option of routing to a waste water retention basin for dispcsal with the combined station effluent. The nominal total dissolved solids for continuous operation of steam generator blowdown is 1.5 mg/1. This waste is subject to NRC and EPA effluent limitations as discussed in subsections 3.5.2 and 5.1.1 respectively.

mimm VEGP-OLEER-3 3.6.2.1.2 Wet Layup Waste In addition to the above requirements for normal operation, chemical additions are required for wet layup of a steam generator during extensive plant outages. A hydrazine concentration of between 75 and 250 mg/l is required for wet layup of a steam generator. Based on the maximum hydracine cancentration of 250 mg/l and a wet layup volume of 32,894 gal, it is estimated that 25 gal of 35 percent hydrazine solution would be required per steam generator or 100 gal per unit per cold shutdown. Ammonia is also added to the steam generators during wet layup tc maintain an appropriate pH usually between 10.0 and 10.5. Approximately 10 ppm of ammonia is required to yield a pH of 10.0.

When the plant starts up following a cold shutdown, the wet layup wastes will be directed to the waste water retention basin for pH adjustment prior to discharge. This waste is subject to

, EPA effluent limitations as discussed in subsection 5.1.1.

6 3.6.2.2 Auxiliary Boiler Blowdown f

During operation of the auxiliary boiler, about 10 gal / min of h blowcown is normally discharged for the two units. A sump in l1 the auxiliary boiler room collects the blowdown and floor drainage (FSAR subsection 9.3.3) This sump normally discharges

{ tc the turbine building oily waste separator and then to the e

  1. waste water retention basin. The blowdown temperature does not y

exceed 200 F in order to maintain acceptably low levels of oil in the discharge from the oily waste separator.

3.6.2.3 Startup and Eculpment Cleaning Waste y Prior to startup and during pipe cleaning operations, the I condensate and feedwater and other plant systems are flushed and

- if necessary chemically cleaned to remove dirt, grease, oli, g rust, and mill scale. Cleaning will be accomplished by one of the following eperations-.

VEGP-OLSER-3 concentration. This will be followed with a rinse of demineralized water. ,

ll 2. Rust and mill scale will be removed from the system by circulating a heated organic acid solution for several hours.

3. Following the cleaning, the system will be flushed with rinses consisting of demineralized water lll and/or passivating chemicals.

Estimated total water volume used in a complete cleaning would be approximately 9,000,000 gal per unit. Wastes from this flushing process will be directed to the startup ponds for suspended solids removal before discharge to the Savannah River. There are two ponds, one an unlined pond with a capacity of 5 x 10' gal for short term storage and one lived (0.100-in.

high-density polyethylene) pond with a capacity of 3 x 10' gal for long term storage. The waste water from the startup ponds is discharged to the blowdown sump. Assuming that water flushing is sufficient, the startup waste is subject to EPA effluent limitations and standards for low volume wastes.

If chemical cleaning is required, treatment in the startup ponds will conform to EPA effluent limitations for metal cleaning wastes as discussed in subsection 5.1.1. The estimated quantities of chemicals used for chemical cleaning is chown in table 3.6-3.

Periodic nonradioactive operational equipment cleaning wastes will also be discharged to the startup ponds. The amount of cleaning waste involved will not be greater than that used during preoperational cleaning.

3.6.2.4 Water Treatment Plant G The water treatment plant is essentially the same as discussed in CPSER subsection 3.7.3. However, there is only one water treatment plant due to the decrease in the plant size from four to two units.

O 3.6.2.5 Liquid Radioactive Wastes Systems for processing liquid radioactive wastes are described in subsection 3.5.2.

Oily wastes are treated by an oily waste separator and meet the EPA effluent limitations jg for low volume waste oil discharge as discussed in subsection 5.1.1.

3.6.3 LIQUID DISCHARGE

SUMMARY

As shown in figure 3.3-1, the low volume waste streams are #

collected in the waste water retention basin. The basin is a l1 corrosion-proof, lined basin that provides aeration and retention time for the wastes. The basin consiste of two compartments, one side being used to handle normal waste streams and the other compartment providing holdup capacity for waste requ'. ring treatment. Each compartment is sized for the waste generated for both units. Any treatment of the waste is done manually as needed based on the results of periodic samples.

The solids removed from the waste water retention basin is discussed in subsection 3.6.4.

Liquid wastes from the waste water retention basins, the blowdowns from the nuclear service cooling water toweta and natural draft towers, and any dilution flow necessary to meet 10 CFR 20 limits are combined in the blowdown sump. The liquid radwaste is injected into the discharge pipe downstream of the blowdown sump.

The characteristics of the waste streams and of the combined effluent discharge to the Savannah River are shown in table 3.6-2. The plant waste discharge conforms to the requirements discussed in subsection 5.1.1.

3.6.4 CHEMICAL AND BIOCIDE SOLID WASTES llf The VEGP chemical and biocide solid wastes consist of settled solids from the waste water retention basins and the cooling tower basins and salt drift emissions from the cooling towers.

3.6.4.1 Settled Solids Removal Each natural draft cooling tower has a solid deposition rate of approximately 2.5 lb/ min into the basin. The basins have a desilting channel that leads to the 24-in. blowdown line which goes to the blowdown sump for discharge into the river. The towers are also equipped with access ramps so that silt and llh sludge buildup may be removed. This is expected to occur during 3.6-8 Amend. 1 2/84

L('] Solids removed from the waste water retention basin will also be disposed of in an upland disposal site. Previous operating experience has revealed that these solids and cooling tower 1 settled. solids are not hazardous (see section 5.6.3) and can be disposed of in an approved upland disposal site. ,

L O 3.6.4.2 Cooling Tower Salt Drift Emissions Salt drift emissions from the natural draft cooling towers for a four-unit plant are discussed in CPSER subsection 5.3.2. The NRC staff concluded (FES paragraph 5.5.1.1? that the effects of deposition of cooling tower salt drift would be negligible. The decrease in plant size.from four to two units further reduces these effects. Additional information on salt drift emissions is provided in responee to questions E290.3 and E451.17. 1 O

VEGF-OLSER-3 3.7 SANITARY AND OTHER WASTE DISCHARGES 3.7.1 SANITARY WASTE

.The. sewage treatment plant treats waste water generated during.

both conctruction and plant operation. The treatment concept is the same as described in Construction Permit Stage Environmental Report (CPSER) section 3.7, but specific aspects of the

. processes (e.g., flow, retention time, and chlorine residual)

.( )

.have changed'since that time as shown in table 3.7-1. During normal operation, the maximum sanitary flow from the plant is

.24,000 gal / day. This flow is based on a total population of 664 persons using an average of 35 gal per capita per day during plant operation.

The. effluent from the sewage treatment plant is ccmbined with other station effluents (section 3.6) prior to discharge to the Savannah River. The characteristics of the combined station effluent is described in table 3.6-2. The sanitary waste effluent will comply with the Environmental Protection Agency effluent guideline limitations as discussed in subsection p 5.1.1.

'Approximately 3000 gal of sludge per year are produced by the sewage. treatment plant. Sludge is collected and transported by truck to an approved' disposal area.

3.7.2 AUXILIARY BOILER EMISSIONS TO AIR

'The VEGP has an auxiliary boiler which supplies auxiliary steam toLvari'ous plant 1 systems when main steam is not available. The

. oil-fired boiler is rated for 190,000 lb/h steam with an operat-

'ing. pressure of'200 psig. The boiler will be operated in accord-

- .ance with tne State of Georgia permit issued February 17, 1981.

, ,_) Emission limitations prescribed in that permit are es follows:

A. The consumption of fuel oil during initial startup and system check shall not exceed 12,500 tons / year.

.B. .Once operational, the total emissions of SOz will not

) exceed 40 tons / year.

r '

3.7-1

VEGP-OLSER-3 h 3.7.3 DIESEL GENERATOR EMISSIONS TO AIR Each unit has available two diesel-powered generators which are designed to supply auxiliary power in the event of loss of offsite power. The diesel generators are rated at 7000 kW each and burn 3600 lb/h of no. 2 diesel fuel oil at full power. It ic expected that each diesel generator will be operated once a month for 1 to 3 h for test purposes.

If each of the four 7000-kW diesels are operated for a total of h 2 h/ month, the total expected annual emissions are:

A. SO 2 -

1.7 tons / year.

B. NO x - 10.7 tons / year.

In addition, there is a 750-kW diesel generator which serves as the standby power source for the security lighting system and technical support system in the event of loss of the normal ac power supply. The emissions from this generator are insignif-

~icant in compaffson to the standby auxiliary power diesels because of its size (750 kW compared to four generators at 7000 kW each) and the projected infrequent time of operation.

l}

Based on these low levels of emissions, December 22, 1981 (J. L. Ledbetter letter to T. E. Byerley), theStataofGeorgi'onl1 exempted the diesel generators from air quality permitting requirements.

3.7.4 OIL LEAKAGE Oil leakage is discussed in CPSER subsection 3.8.2.

3.7.5 FLUID BED DRY WASTE PROCESSOR EMISSIONS TO AIR The fluid bed dry waste processor is described in detail in Final Safety Analysis Report (FSAR) section 11.4. Radioactive emissions for the building that houses the fluid bed dry waste processor and other volume reduction equipment are analyzed in FSAR section 11.3.3.

The expected annual nonradiological emissions from the fluid bed dry waste processor are:

5.1.1 EFFLUENT LIMITATIONS AND WATER QUALITY STANDARDS The water quality of the Savannah River in the vicinity of VEGP is classified as " fishing" by the State of Georgia.'1' The following criteria are applicable for a fishing classification

. to the Savannah River at VEGP:

A. Dissolved oxygen - A daily average of 5.0 mg/l and no less than 4.0 mg/l at all times.

pH - Within the range of 6.0 to 8.5.

[~}

y, B.

C. Bacteria - Fecal ~ coliform not to exceed a geometric mean of 1000 per 100 ml based on at least 4 samples taken over a 30-day period and not to exceed a maximum of 4000 per 100 ml.

D. Temperature - Not to exceed 90*F; at no time is the temperature of the receiving waters to be increased more than 5 F above intake temperature.

E. Toxic wastes and other deleterious materials - None in concentrations that would harm man, fish and game, or other beneficial aquatic life.

A mixing zone is permitted if such a zone is necessary and will not create an objectionable or damaging pollution condition.

In addition to-the water quality criteria established for the

VEGP-OLSER-5 The State of Georgia will regulate the VEGP discharges through the National Pollution Discharge Elimination System (NPDES) permit. The NPDES permit application was submitted to the State of Georgia Environmental Protection Division on November 3, 1983 lh (T. E. Byerley letter to G. B. Welsh). A copy of the 1

application was provided to the Nuclear Regulatory Commission (NRC) by D. O. Foster's letter to E. G. Adcasam dated November 9, 1983. A copy of the final permit will be provided so the NRC at the time of its issuance. Section 12.1 lists permits, certificationa, and approvals dealing with the water quality required to cperate the facility.

lh 5.1.2 PHYSICAL EFFECTS The thermal effects of the effluent of VEGP were discussed in the Construction Permit Stage Environmental Report (CPSER) subsection 5.1.1. Since the submittal of the CPSER the design of the discharge has been changed from a submerged multipc_t diffuser to a single point discharge pipe. This sec ion

-~~a ddresses the physical effects that the heated effluent will have on the river an( describes the method used ta determine these effects. This section discusses only the physical effects of discharging a heated effluent; the potential effects on biota g

from interacting with the elevated temperature water within the mixing zone are addressed in subsection 5.1.3.

5.1.2.1 Description of Plant Thermal Discharge The bulk of the waste heat from VEGP is rejected to the atmosphere by the cooling towers. During normal operation, the combined heat rejection for the turbine plant circulating water cooling towers and the nuclear service cooling water (NSCW) towers is 8200 x 10' Btu /hfunit. The NSCW towers reject about 2.5 percent of the total plant heat.

Blowdown is discharged from the cold side of the cooling towers and combined with plant low volume wastes (see section 3.6.2) in the blowdown sump after which the effluent is discharged to the river. (See subsection 3.4.5 for a description of the discharge system.) The amount of effluent being discharged varies depending on cooling tower operation (e.g., evaporation, drift, blowdown, desired concentration factor, etc.), the contribution from intermittent flows, and the need of dilution flow to meet 10 CER 20 requirements.

The plant effluent-increases the river temperature near the

,(')-

discharge point. Georgia Power Company submitted a study to the 1 NRC on May 1,.1981 which discussed the spatial and temporal variations of the thermal plumes in the Savannah River using a

' submerged single point dischargo inclieu of the multiport

-diffuser addressed in the CPSER. The study was carried out for 3

the minimum river flow of'5800 ft /s. Any higher river flows

()'L

- produce smaller mixing zones because of the larger amounts of ambient water:available for dilution of the plant effluent.

Plume analyses were performed for river-temperatures representative of the minimum (41*F) and maximum (79 F) conditions.

The: maximum. difference in temperature between ambient river and discharge is.43*F for the cases studied. This occurs when two

- units are operating with two-unit radwaste discharge and no dilution flow to meet 10 CFR 20 limits.

The thermal plume' analysis was based on the work of E. A.

Hirst'2' for a round jet discharging into a flowing ambient

=

.wate r. body. Six basic equations, conservation of mass, energy,

_ ,/ . chemical concentration, and momentum (three components), were solved to describe the jet properties along the plume centerline. The complete results of the thermal plume analysis have been previously submitted to the NRC.'8' Table 5.1-2 summarizes-the S F-AT and 2 F AT isotherms for two cases from the study included in-the NRC's evaluation of the thermal plume.

As a_ result of the study by Georgia Power Company and the NRC's evaluation,.the Construction Permit for the VEGP was modified to

- delete the. requirement for a multiport diffuser on January 29, 1982.

l1 The heated water _ discharge from VEGP will not exceed any temperature _ limits discussed in subsection 5.1.1-outside of a small mixing zone. The largest mixing volume within the 5 F isotherm is estimated to'be 1300 ft'. As stated earlier, the allowable mixing zone will be defined by the State of Georgia as

VEGP-OLSER-5 ggg 5.1.3 BIOLOGICAL EFFECTS 5.1.3.1 Intake Operation and Its Effects 5.1.3.1.1 Entrainment Studies completed by McFarlane, et al . , ' at the Savannah River Plant and by Georgia Power Company at the VEGP indicate that entrainment of fish eggs and larvae at the intake structure will be minimal and will not have a significant effect on the fish population in the river (see section 6.1). Under minimum river flow conditions, entrainment losses represent about 0.65 percent of the river's ichthyoplankton populations. This removal is not expected to have an adverse effect on these populations or on the organisms that feed on them.

Studies conducted at the Savannah River Plant revealed that fish eggs were rarely found in canal icthyoplankton samples.

The velocity decreased drastically in the canal in comparison to the main channel of the river, causing fish eggs and larvae to settle to the bottom. This means that not all eggs and larvae which enter the intake canal would necessarily be entrained.

5.1.3.1.2 Impingement The VEGP Construction Permit required that Georgia Power Company submit a study regarding impingement prior to construction of the intake structure. Georgia Power Company submitted information to the NRC concerning impingement at VEGP on January 28, 1981. In a letter from the NRC dated April 29, 1981 (R. L. Tedesco to W. E. Ehrensperger), the NRC concluded that no significant effects on the fishes of the Savannah River will result from impingement.

A comparison of the impingement studies completed at the O Savannah River Plant by McFarlane, et al . , ' ' ' and of the VEGP data was made to reach reasonable impingement estimates at the VEGP. Intake velocities for VEGP are presented in section 3.4.

s Impingement at VEGP should be low because of its single intake O structure, low intake velocities, and short intake canal which reduces the amount of available area for the population of certain species to develop. Fish will be impinged, but the number of individuals impinged should be low and no single species should dominate the impingement sample.

VEGP-OLSER-5 5.2 RADIOLOGICAL IMPACT FROM ROUTINE OPERATION 5.2.1 EXPOSURE PATHWAYS

^

5.2.1.1 Biota Other Than Man Aquatic biota may be exposed to external radiation from radionu-() clides in the water and sediment and to internal radiation from the assimilation of these radionuclides. In addition to uptake via the ingestion of food organisms, fish and invertebrates can

acquire radionuclides through direct absorption from the water and can at least partially assimilate radioactivity from ingested sediment. Figure 5.2-1 is a flow chart representing the transfer.of radionuclides through the aquatic ecosystem.

The organisms which constitute'the lower trophic levels of the aquatic food web (plankton and benthic invertebrates) in the Savannah River and Beaverdam Creek are described in subsection 2.2.2. Dominant phytoplankton are the green algae (Chlorophyta),

blue-green algae (Cyanophyta) and diatoms (Bacillariophyceae).

Genera that will predominate include the rotifers (Keratella,

(~}

\_- Polyarthra, and Synchaeta); the cladocerans (Bosmina, Ceriodaphnia, and Daphnia); the copepods Diaptomus, Mesocyclops, and Cyclops); and the larvae of the dipteran, Chaoborus. Rotifers probably will be the dominant taxa in the river, while the cladocerans and copepods will be secondarily dominant. Benthic macroinvertebrates typically play an impor-tant role in the aquatic food web, serving as a link between the detrital level and the higher trophic levels. Mayily larvae,

. dipteran larvae, and mollusks are examples of the benthic macroinvertebrates that are found in the Savannah River in the vicinity of the VEGP. Fish feeding upon the plankton, benthic

.macroinvertebrates, and other fish constitute a higher trophic g$ level of the aquatic food web.

V' The terrestrial ecology of the VEGP area is described in subsection 2.2.1. Terrestrial biota may be exposed to external radiation from immersion in the plant's gaseous effluents, from swimming in water containing the plant's liquid effluents, and gg from direct shine from radionuclides that have deposited on the

(,7 _ ground and shoreline. Internal exposure of terrestrial organ-isms may' result from the inhalation of radioactive materials from the plant's gaseous effluents and from the ingestion of foods that have assimilated radioactive materials from both gaseous and liquid plant effluents. Figure 5.2-2 presents the pathways by which terrestrial biota other than man are exposed

! (gs), - to radioactive material released from the VEGP.

The routes of internal exposure to terrestrial biota other than man are highly varied.due to the diversified feeding habits of 5.2-1

f VEGP-OLSER-5 h the animals living in the vicinity of the site. The vegetation in the region will receive radionuclides from deposition onto the plant foliage and from the uptake of radioactivity initially deposited on the ground. Deer, rabbits, squirrels, and other herbivorous animals could then be internally exposed from the ingestion of this vegetation. In turn, foxes, bobcats, and other predatory animals living in the vicinity may be internally exposed to radiation from feeding on those animals that have concentrated radionuclides in their flesh.

5.2.1.2 Man As a result of the operation of the VEGP there are several

' potential radiation exposure pathways to man. Figure 5.2-3 presents the various potential pathways. These potential pathways may be divided into two categories, those pathwayc resulting in a radiation dose via internal exposure and those pathways resulting in a dose via external exposure. External exposure to an individual may result from contact with radioac-tivity deposited on the ground, immersion of an individual in a cloud containing radioactive gaseous effluents, direct irradia-tion from the plant, or direct contact with water containing radioactive liquid effluents while swimming or engaging in a ll similar activity. Internal exposures may result from the ingestion of water, various foods, and inhalation.

5.2.1.2.1 Internal Exposure Liquid radioactive effluents from VEGP are combined with cooling tower blowdown, waste water retention basin effluent, and addi-tional dilution flow if required to meet 10 CFR 20 requirements prior to discharge downstream of the river intake structure.

However, internal exposure via the domestic potable weter path-way will be minimal, because the nearest location of potable use of river water is in Beaufort County, South Carolina, approxi-mately 112 river miles downstream of the plant site (paragraph l1 2.1.3.8.2). No crop irrigation with Savannah River water has been observed within 50 miles of the plant site, so exposure from this pathway is expected to be minimal.

Although recreational and commercial fishing within 50 miles of the site is limited, these activities could result in internal exposure through the aquatic food chain (paragraphs 2.1.3.4 and 2.1.3.5).

The remoteness of the VEGP site ensures few human activities g within 5 miles of the plant. There are no dairies, wildlife W preserves, or sanctuaries in the vicinity of the VEGP. However, there are some small rural farms with gardens and small amounts 5.2-2 Amend. 1 2/84

The highest anticipated airborne concentrations in the vicinity of the site due to gaseous releases have been calculated using these meteorological data and the source terms presented in section 3.5. The concentrations are presented in FSAR table 11.3..-3. The concentrations of radionuclides on the ground and in vegetation are controlled by the deposition of gaseous ef-fluente, since irrigation of crop land with Savannah River water is not anticipated. These concentrations are also presented in table 5.2-3 at the nearest resider.ce.

5.2.2.1 surface Water Models The effects of ' liquid radioactive effluents released to the Savannah River from VEGP during normal operation were analyzed using the LADTAP II computer cods'" and initial dilution data obtained from the VEGP thermal plume analysis. c 2 > Based on the calculated releases of radioactive materials in section 3.5, the expected concentratien of radionuclides in the liquid ll effluents discharged to the river is presented in FSAR table 11.2.3-1.

5.2.2.1.1 Transport Models The LADTAP II code is based in part on the calculational models for the estimation of aquatic dispersion outlined in Regulatory Guide 1.113. Data in the VEGP thermal plume analysis were de-termined using the three-dimensional submerged jet model recom-mended in Regulatory Guide 1.113.

For a 15,500 gal / min (34.5 ft'/s) effluent discharge into the Savannah River with 5800 ft'/s minimum flow, the VEGP thermal plume analysis utilizes a dilution factor of 10 for summer discharge conditions and 20 for winter discharge conditions.

For conservatism, the lower dilution factor of 10 was utilized g for the LADTAP II analysis. Furthermore, a transit time of 0.0 W was used.

Although' dose rates from'the river sediment have been calculat-ted, no credit has been claimed for concentration reduction of f radionuclides in the surface water resulting from sediment uptake.

f 5.2.-2.1.3 Water Use Models

[The LADTAP II computer code, in conjunction with tha VEGP thermal plume analysis, was used to calculate the maximum radiological impnet of liquid effluents from the normal operation of VEGP. It

.was assumed that the maximum exposed individual catches and con-

-sumes all his fish'within the'immediate vicinity of the discharge plume. Furthermore,-it was assumed that the maximum exposed individual spends all'his time on tlie shoreline in the vicinity of:the discharge plume and obtains all his drinking water from

'that same area.

~5.2.2.2' Groundwater Models As-previously noted, all. liquid effluents discharged from the plant are routed to the Savannah River. Subsection 2.1.3

-identifies two distinct underground aquifers at the-plant site, but due toJthe hydraulic gradient and permeability of.the re-

.gion, both_aquifere and surface water drainage are directly to

-the river. Hence, the radiological' impact from the groundwater pathway will be negligible. (See FSAR-section 2.4-for additional information on groundwater.)

Numerous studies have been made on tha effects of radioactivity on biota "' " . Applying the same results of these referenced studies to evaluate the potential effects on river biota, there should be no perceptible impact on biota from the radioactive material released by the VEGP.

5.2.4 DOSE RATE ESTIMATES FOR MAN O

5.2.4.1 Liquid Pathways The calculated maximum individual doses from aquatic pathways of radiation exposure are based on radionuclide concentrations calculated to occur in the area of the river near the effluent discharge pipe. These theoretical doses are presented in table 1

5.2-5 (see FSAR section 11.2, table 11.2.3-4).

These doses tere obtained using the LADTAP II code which utilizes the calculational models, usage factors, and dose factors outlined in Regulatory Guide 1.109.

5.2.4.2 Gaseous Pathways The calculated maximum individual doses from gaseous pathways of

  • exposure are based on the atmospheric dispersion and deposition rate factors to the nearest receptor within 5 miles of the plant as presented in tables 5.2-1 and 5.2-2 (see FSAR section 2.3, tables 2.3.5-10 and 2.3.5-11).

1 The resultant doses are presented in table 5.2-6 (see FSAR section 11.3, table 11.3.3-4). The doses were obtained using the GASPAR code which utilizes the calculational models, g

usage factors, and dose factors outlined in Regulatory Guide 1.109.

5.2.4.3 Direct Radiation from Facility l

Since access to the area surrounding the plant will be restrict-ed, it is not expected that any member of the general public will be close to the plant long enough to receive any measurable radiation from this pathway. In addition, all principal radia-tion sources within VEGP are shielded so that the radiation level in all unrestricted areas is kept below 0.25 mrem /h. At the site boundary an annual dose from this pathway is expected ,

to be less than 1 mrem, as described in FSAR section 12.4. i 1

5.2-6 Amend. 1 2/84 l

VEGP-OLSER-5 5.2.4.4 Annual Population Doses The radiological impact on the' general population depends not only on:the release of radioactive effluents from VEGP but also if )n upon the land'and water use of the region surrounding the site.

' Subsection 2.1.3~of-this-report presents a detailed discussion of: land land water usage in the. area, and FSAR subsection 2.1.3

. presents the anticipated population data for this area. Based

upon.the information supplied in these sections, conservative

-[ )

estimates have been made of the exposure of'the general population to radiation.

The population-integrated doses due to radioactive material in the plant's liquid (ffluents have not been evaluated because of

'the: remoteness of the site,. minimal. recreational usage of the river, lack of river water usage for irrigation, and~1ack of

river water usage for potable water supply within 50 miles of ,

the plant site - aus noted in sub.3ection .2.1. 3.

The1 annual'50-mile population doses from gaseous effluents were Jevaluated using the GASPAR code in conjunction with site

_ . . specific data-as noted in subsection 5.2.2. 'The following

' ; (~Tx . principal exposure pathways were evaluated and outlined in table

?q / - 5.2-3:. noble gas submersion, inhalation of airborne effluents,

. ingestion.of contaminated foods (milk, meat, and vegetation),

and external-radiation from activity deposited on the ground.

Furthermore, the'GASPAR code was used to evaluate the doses

. received.by~the population'of the contiguous United States for

- the : same exposure pathways as in table 5 ;2-3. These doses are

. presented in table 5.2-4 and are based on site specific data and

. conservative valuesTprovided in the code.

5.2.5 '

SUMMARY

~OF ANNUAL RADIATION DOSES

( The estimated annual. radiation doses ~to the regional population i (i.e., out to a distance of 50 miles from the site) and-U.S.

population are outlined in detail in tables 5.2-7 and 5.2-8, l1 respectively. This tabulation includes the total of the whole

, bodyLdoses to.the population attributed to gaseous effluents and T  : 'the total of the thyroid' doses to the population from 1:1 .

tradioiodine and~particulates.

Furthermore, tables 5.'2-5 and 5.2-6 (see FSAR tables 11.2.3-4 l1 and/11.3.3-4) provide.a comparison of the calculated individual doses to the design objectives outlined in 10 CFR 50, Appendix E 1 -I. The results indicate that the calculated exposures are 3 within the< design objectives. ,

VEGP-OLSER-5

.O The transmission lines associated with the VEGP will have no significant environmental impact due to ozone formation as discussed in CPSER paragraph 5.4.14.

5.5.2 ENVIRONMENTAL EFFECTS OF MAINTENANCE OF THE TRANSMISSION SYSTEMS LRights of way will be recleared every 3 years; in addition, a

O herbicide will be sprayed in selected areas by helicopters every 6 years (or less frequently depending on local vegetative conditions). The reclearing is accomplished with rotary or drum mowers and with some hand clearing using chain saws and hand tools. No permanent access roads will be maintained along the rights of way. Any damage to rights.cf way during maintenance will be repaired. Herbicide for reclearing will be sprayed in compliance with all U.S. Environmental Protection Agency and State of Georgia Environmental Protection Division regulations. Present practice is to spray herbicide using a helicopter with a microfoil boom. Spraying is limited to periods when the wind does not exceed 1 1/2 to 2 mph. The application rate is in accordance with label directions to L

adequately.reelear the rights of way. Only broad-leafed plants

are killed. This process does-not adversely affect either pines

! and other vegetation near the rights of way or grasses and narrow-leafed plants on the rights of way.

Part of the' land management program of GPC is the right of way o conversion program in which GPC will pay the landowner to plant the cleared right of way in pasture, crops, or game food plots.

Planting is limited to grasses, crops, and low-growing shrubs

- and trees that will not reach a height that will hinder the operation of the transmission lines. In addition, the edge effect created by clearing or planting crops along rights of way will enhance wildlife habitat.

5. 7- RESOURCES COMMITTED The. operation of the VEGP will involve the commitment and use of

_ various natural resources and will result in certain irretriev- '

OL iableJand' irreversible commitments of natural resources. Because ,

of_the; reduction'from four-units to two units at VEGP, the committed resources will be substantially reduced from those 7

summarized in the Final Environmental' Statement and chapter 10 of the Construction Permit _ Stage Environmental Report (CPSER).

^

'( )~ ~ Air,_ water, and land commitments are retrievable upon cessation of. plant operation. At the end of the useful life of this plant, the buildings could be removed and the grounds returned to essentially their original condition; however, it is most likely that the concrete structures would remain (subsection 5.8).

1 The irretrievable resources committed at the VEGP would be the uranium used in the form of nuclear fuel and the materials used for construction of the plant. Of these resources committed, _

only the nuclear fuel is unique,.because the commitment and use of air, water, land,-and construction materials would be similar for-a fossil plant.

A number of the following acreage figures have changed since c publication of the CPSER. These changes are due to various reasons, such'as reduction in the number of units and design changes. The following resources are committed for the operation of the VEGP:

I b A. Land

1. Site - The VEGP site consists of 3169 acres of E land. A list'of plant facilities and acreages is

'_ found in subsection 2.1.3. The plant facilities will occupy approximately 717 acres of the site, l thus. changing their use from agricultural and

timber production to. electrical generation. The

() remaining 2452 acres will either be managed in accordance with acceptable land tanagement 1 techniques or,be landscaped, fertilized,_and i

reseeded after construction is completed. At the end of the useful life of the plant, the land can -

be returned to agricultural _or other uses with the r s necessary expenditures of money and human effort. *

2. Trrnsmission lines - The offsite transmission line lf rights of way will consist ~of approximately 2958 I

acres which will be removed from the growing of LJ timber and agricultural products; however, this

! s ' land can be returned to its former state if l

'~

desired.

VEGP-OLSER-5 llh

3. Access railroad - The offsite access railroad spur will consist of approximately 386 acres which will be removed from the growing of timber and agricultural products; however, this land can be returned to its former state if desired. llh
4. The total area of the plant site, the transmission line rights of way, and the access railroad spur is approximately 6500 acres, which is about 0.12 percent of the land within a 50-mile radius of the site. The acreage used is very similar to the lh land within the 50-mile radius. No unique or unusual areas will be consumed by the land use.

B. Water Savannah River water converted to water vapor by operation of the VEGP cooling towers represents a minor loss to the Savannah River (at maximum consumptive use: approximately 1,2 percent of 5800 ft'/s at low flow and 0.6 percent of 10,300 ft'/s at average flow). This water vapor will be returned in the form of precipitation due to natural phenomena. Groundwater g used for makeup, drinking, etc., will be obtained from W wells at a raaximum rate of approximately 2300 gal / min and average rate of approximately 1333 gal / min. The VEGP water consumptive use is discussed in subsection 3.3.3.

C. Uranium The reactors are fueled with uranium dioxide pellets enriched in the fissionable isotope U-235. The initial fuel load for each core consists of 193 fuel assemblies divided into regions with average enrichments of 2.1,

2. 6, and 3.1 weight percent U-235. Each enrichment region represents approximately one-third of the initial core. Fuel requirements for operation of the reactors depend upon fuel management practices.

However, a typical annual cycle would require replacement of approximately one-third of each core annually. Assuming 75 percent capacity, the plant would require an annual commitment per reactor of approximately 440,000 lb of U 30s (natural uranium),

assuming no reprocessing of spent fuel. Over the plant's 40-year life, this represents a commitment of approximately 17,600 tons of U 3 0s or approximately 0.5 percent of the total estimated uranium resources in the United States in the forward-cost category of $100 per lb of Uso, or less.

5.7-2

() VEGP-OLSER-5 D. Construction Materials

- Construction materials in the form of steel, concrete,

(  ! timber products, etc., cannot be practically retrieved and are thus consumed.

E. Wildlife Habitats

,s The area that will be removed from biological pro-( ) ductivity and used for buildings, roads, parking, and other facilities will total 717 acres or 23 percent of the site's total 3169 acres. Approximately 1777.9 acres (56 percent) will be managed in accordance with approved land management practices (see D. O. Foster letter to E. G. Adensam, January 9 1984).Approximately 600 acres of pine and mixed pine land on the site will be burned under control conditions during the months of January or February 1P84 and periodically throughout the life of the plant. The controlled burn activities will enhance the productivity of the areas burned.

Burning activities of these types are accepted land management practices. These activities are conducted

[~N during the winter months in order to minimize the

(_/ damage to trees and to take advantage of the wet sublayer. y

. The portions of the site to be burned are prepared by developing fire breaks around them. These fire breaks were developed by the Georgia State Forestry Commission. Furthermore, the burn activities will be supervised by representatives of the Forestry Commission and Georgia Power Company. Only portions of the site will be burned at any one time and this activity will be coordinated with expected traffic.

The burning activities will be conducted during periods f3 of low but steady wind.

l

() The areas to be burned are far removed from plant facilities. Plant supervision will be notified before any burn activity is initiated. The plant fire brigade will also be notified; however, the burning activity r~s will not require their participation.

)

'~

Of the 1391.2 acres that were originally disturbed by construction, 519.6 acres will be fertilized and reseeded and 136.5 acres will be involved in onsite transmission lines and 18.6 acres will remain as ponds.

(-)

(_j Inisting habitat including transmission corridors may be enhanced due to increased edge effect created by planting and landscaping following the construction 5.7-3 Amend. 1 2/84

VEGP-OLSER-5 lll phase. The acreage used for offsite transmission lines wi.ll also create an edge effect and thus enhance wild-life habitat. The terrestrial habitat within at least a 5-mile radius of the site is very similar to that found on the plant site; therefore, a very small llh percentage of habitat will be lost from the total area. There should be no significant impact to the aquatic habitat, because the cooling towers will be used to minimize thermal effects and chemical releases will meet effluent guideline limitations as discussed in section 5.1.

lh The operation of the VEGP will affect the environment in terms of the irretrievable and irreversible commitment of natural resources to the extent indicated above. However, the extent to which the use of the environment is curtailed is not considered serious and is warranted due to the benefits of the electrical power produced. Chapter 11 presents the overall cost-benefit analysis for the VEGP.

( VEGP-OLSER-5 5.8 DECOMMISSIONING AND DISMANTLING Prior to_ decommissioning the VEGP, GPC will have the benefit of l( )!

~

industry experience and technical improvements in future decommissioning. Before the end of the plant's useful lifetime, j GPC will prepare a proposed decommissioning plan for review by

'the NRC. The plan will comply with NRC decommissioning rules

'andiregulations'then in effect.

'(~

While the specific regulatory guidance for decommissioning a nuclear plant 40 years in the future is likely to vary from present guidance, it is anticipated that the general guidance contained in Regulatory Guide 1.86 will be applicable. Under the safe storage with deferred dismantlement or permanent entombment decommissioning alternatives, GPC would seek a possession-only license for.the facility. If dismantlement is

-chosen, GPC would seek to eventually terminate all facility licenses. The decontamination requirements of Regulatory Guide 1 186 or.whatever future documents may apply will be utilized in

-the development of the decontamination.and decommission.ing plan.

5.8.1 DECOMMISSIONING ALTERNATIVES While decommissioning will occur only after the termination of l ~ plant-operation, it is expected that it will be accomplished j through the application of one of the presently available

alternative methods. The-experience gained in the continued use L 'of.these methods and any developing variations for nuclear plant
decommissionings-in the interim years will further ensure the

[ effectiveness of the VEGP_ decommissioning.

Currently, three alternatives for decommissioning commercial nuclear power reactors have been considered in several studies.

These are identified in references 1, 2, and 3 as:

.O A. Immediate Dismantlement (DECON)

The removal of all . radioactive materials and complete site decontamination within approximately 4 years after cessation of plant operation.

l B. Safe Storage with Deferred Dismantlement (SAFSTOR)

The security of radioactive materials and contamin-ated areas for an extended period of time after the ,

, cessation of plant operation to allow time for short- >

l q, lived radioisotopes to decay. Under this option, t dismantlement is deferred for up to 100 years.

VEGP-OLSER-5 ll)

C. Permanent Entombment (ENTOMB)

The removal of radioactive liquids, spent fuel, and certain highly radioactive components (such as reactor internals) followed by the permanent sealing of the g

structures to prevent future access. An appropriate and continuing surveillance program is then placed into operation to ensure that entombment integrity is indefinitely maintained.

Reference 3 lists 29 reactor facilities in the United States that have been removed from service. Nine of these plants were dismantled, and another was decontaminated and converted for public access as a national monument. Three plants were entombed. The remainder are in passive safe storage, with some dismantlement performed on several of the plants.

The Elk River Reactor decommissioning is most nearly exemplary of the application of the removal / dismantling technology to a commercial power plant. Although the sizes of the facilities decommissioned to date have been significantly smaller than VEGP, the experience gained reinforces the conclusion that VEGP can be decommissioned while protecting the health and safety of g the public. W 5.8.2 COST OF DECOMMISSIONING The cost of dece"missioning a nuclear plant depends upon the method of decommissioning. A number of decommissioning cost estimates have buen developed by utilities, various industry organizations, and the NRC. While the studies vary somewhat in their conclusion, they all indicate that the entombment option is the least expensive. Estimates for entombment costs vary from about $13 million (1980) to about $38 million (1980).

The effect of a safe storage period prior to dismantlement on the total cost of decommissioning is not well defined. lll Reference 2 estimates the cost of immediate dismantlement as

$54.5 million (1980) and the cost of safe storage with subsequent dismantling as $34.9 million (1980). Reference 3 places these costs at about $38 million (1980) and $49 million (1980), respectively. Based on available information, the cost of decommissioning should be in the range of $50 million h (1980).

5.8.3 SAFETY IMPACT OF DECOMMISSIONING The only significant hazard to the public health and safety or O to the environment from decommissioning operations is the ,

A wire mesh basket containing unglazed porcelain cpheres with an approximate surface area of 1.2 ft2 was collected four times at each station.

In the laboratory, samples were washed through a U.S. No. 30 sieve and preserved. Macroinvertebrates were sorted with the aid of a three-diopter illuminated magnifier.

6.1.1.2.3 Drifting Macroinvertebrates A study of drifting organisms in the Savannah River began September 1973.as part of a preoperational evaluation of the biota in the vicinity of VEGP. The purpose of this study was to collect baseline data on planktonic macroinvertebrate numbers in the Savannah River from river miles 150.6 to 151.2.

Savannah River drift surveys were conducted monthly from September 1973 through August 1974 and from September 1980 through August 1981. During each survey, day and night drift ll samples were collected at two stations located in three transects. The transects are located at: river mile 151.2, 0.3 miles upstream of the proposed site of the intake structure (see figure 6.1-2); river mile 150.9, the proposed site of the intake structure; and river mile 150.6, 0.3 miles downstream from the intake structure. Each station was approximately 40 ft from each bank. A single 15-min sample was obtained at each station on a transect.

Drift samples were obtained from paired drift nets 0.5 m in diameter made of 760-u mesh nylon. The amount of water filtered was estimated from the total flow measured at the mouth of one net using a General Oceanics model 2030 flowmeter. The net was placed 6 to 12 in. from the river bed for 15 min. The samples were sorted in the laboratory with the aid of a three-diopter illuminated magnifier.

6.1.1.2.4 Plankton A study of the plankton community of the Savannah River was conducted between January 1981 and September 1981. The purpose of the plankton study was to describe the Savannah River plankton community in the vicinity of VEGP.

\- 6.1.4.3.4 Birds Several different methods were used to conduct bird surveys.

Songbird utilization of the site was established by developing a checklist of all birds observed on the site. A raptorial 4

(~) survey (hawks and owls) was conducted to determine what extent the site was used for nesting. Upland game birds, especially

. quail and doves, are important species, and any observation of either was recorded to determine their relative abundance on the site. Waterfowl and wading birds are mostly migratory species that utilize portions of the site seasonally.

Songbirds were surveyed for a 3- or 4-day period each montl.

. beginning in October 1980 through September 1981. Most surveys were conducted during peak bird activity beginning at dawn and lasting approximately 3 h. All species identified were noted on a qualitative species list. Data from additional surveys and

-incidental sightings were included in the species list. A

different habitat was surveyed each day to record a maximum number.of species during each monthly survey.

The raptor (hawks and owls) survey consisted of a daylight census, nest search, and nighttime owl census. This survey was' conducted each month during the fall, winter, and spring starting in December 1977 through September 1981. The daylight census consisted of ten observation stations located around the perimeter of the site. A minimum of 5 min was spent at each station during the period of peak raptor activity in the i afternoons. The nest search was conducted by walking through possible nesting habitats from Decer.ber through June for the duration of the survey. Any possible nests were watched periodically throughout the nesting season for activity.

V During the winter months, December through March of the survey, a nighttime owl' census was conducted covering all likely habitats on the site. The owl census started approximately 30 min before sunset and continued into the night hours. All owls

_- r 3 heard were listed along with the time, habitat, and approximate

' (") location. All raptors observed at any time on the site were also recorded.

The number of each species of waterfowl and wading birds observed was recorded along with habitat and season. The site was surveyed monthly, specifically for these species. Data included any waterfowl or wading bird observed durin9 the songbird survey and any incidental sightings. -

6.1.4.3.5 Mammals 6.1.4.3.5.1 Small Mammals Poculation Survey. Rats, mice, and shrews were collected in snap traps, pitfall traps, and Sherman live traps. Live traps and snap traps were set in line tran-sects in different habitats. Pitfall traps were permanently placed in areas adjacent to the snap trap and live trap tran-sects. The survey was conducted for three to four consecutive nights each month from November 1980 through August 1981. Traps were checked in the morning and evening. A reference collection was maintained by GPC biologists.

6.1.4.3.5.2 Big Game Mammals (White-Tailed Deer). A white-tailed deer census was conducted on the VEGP site vicinity from June 1977 through June 1980 utilizing the Tyson track-count method. '" This method has been used by state game and fish departments in the Southeast. Three permanent transects were established along road margins in the vicinity of VEGP. The Post Road transect (figure 6.1-5) was established adjacent to the southeast corner of the VEGP site. The Hancock Landing transect (figure 6.1-6) was 19:ated on the dirt road which forms the northern boundary of the site. The Ebenezer Road transect (figure 6.1-7) was located approximately 2 miles west of the site. The method involved removing all evidence of deer tracks from the sides of the road before dark and counting the fresh tracks the following morning. The number of tracks crossing the transect and~their direction were tallied, while the tracks that did not cross both scraped road margins were not tallied. No at-tempt was made to distinguish buck tracks from doe tracks or to separate age classes, but fawn tracks were noted when observed.

An attempt was made to collect daily counts for four consecutive days on each transect each month from June 1977 to June 1979.

The survey was conducted every other month from June 1979 to June 1980. The number of tracks tallied per mile of transect is l

equal to the density of deer per square mile of deer range, since the average size of a deer's home range is 1 square mile.

The following formula was used to compute the number of deer per equare mile:

6.1.5 RADIOLOGICAL MONITORING

'The. objective of a radiological environmental monitoring program is.to determine the nature and extent of any radiological changes in the environment attributable to plant operation. The program'provides measurements of radiation and radioactive mcterials in the exposure ~ pathways for those radionuclides which

, are. expected to produce the highest potential radiation exposure to individuals as a_ result of plant operation. The program l .provides information needed to determine whether exposures in

J- the environment are within established limits. The preoperational phase of the program is described-in this t subsection:and the operational phase in-subsection 6.2.1. The L general bases for establishing the environmental monitoring

. program are set.forth in reference 5. Additional guidance is L provided by references 6 and 7. ,

-( ~

In the preoperational phase of the program, background radio-logical levels, both natural and manmade, are measured. These background measurements may then be compared with measurements '

to be taken during the operational phase of the program. Also

- ~

during the preoperational phase, procedures and techniques are developed, equipment is evaluated and calibrated, and personnel are trained.

Some samples and monitoring points not expected to be affected I by plant operations will be monitored during the preoperrtional ,

period to establish baseline data. These samples and locations need not be monitored during operation until there is reason to g '

believe that they may become sufficiently affacted by plant W operations to warrant monitoring.

Preoperational r..onitoring began in August 1981. Periods of 6 months to 2 years, depending on the sample, cre usually sufficient to provide an adequate data base for comparison with g-operational data and to provide experience which may improve the w efficiency of the operating program. This period will be extended as feasible; however, the preoperational phase will be concluded at about the time of initial criticality of Unit 1, if not before.

Measurements are taken chiefly at two kinds of locations:

indicator stations where long term or maximum radiological levels attributable to operation of the plant are anticipated; and control stations where radiological levels are not expected to be significantly influenced by plant activities. However, all of the indicator and control stations are susceptible to any radiological effects which might be attributed to the operation of neighboring nuclear facilities, as well as to fallout from nuclear weapon < tests. These could confuse the proper comparison of the radiological levels between the indicator and control stations or between the periods of operation and preoperation when attempting to show the effects of plant operation. Measurements may also be taken at locations of special interest, such as nearby institutions or towns, or at the closest residence. Deviations are permitted from the sampling schedule if specimens are unobtainable due to hazardous conditions, unavailability, inclement weather, malfunction of equipment, or other conditions.

Samples are collected and analyzed according to table 6.1-1.

The locations of the sampling stations are described in tables 6.1-1 and 6.1-2 and are shown in figures 6.1-8 through 6.1-12. g The number and locations of the sampling stations were determined largely by th'e guidance provided in reference 8.

Site specific considerations such as accessibility also influenced some of the locations of the sampling stations.

Changes in the program relative to the description given at the construction permit stage come as a consequence of the experi-ence gained with the operation of the radiological environmental monitoring program at Hatch Nuclear Plant. These changes also reflect developments in the regulatory guidance.

3.1 INTRODUCTION

The VEGP, like any other large industrial plant,'could experience nonnuclear industrial accidents during its lifetime.

Accidents that might occur are small electrical fires, chemical spills, etc. The administrative procedures and safety

(,)

7s equipment at /EGP will limit accidents of this type, so that their environmental consequences will be minimal. The potential hazard from onsite storage tanks to the control room and information concerning the identification of potential hazards in the plant site vicinity from nearby industrial, military, and transportation facilities is discussed in Final Safety Analysis Report (FSAR) section 2.2. The following is a discussion of hazards to the environment.

4 7.3.2 CHEMICALS STORED ONSITE l The types, quantities, and storage location of the major chemicals that will be stored onsite are given in table 7.3-1.

t

(~)N N- Solutions of sodium hydroxide and sulfuric acid are not considered to present any significant threat to the environment because of their low volatility. The failure of tanks containing pressurized gases, except chlorine, will not result in adverse environmental effects. Most of these gases are asphyxiants and are stored in relatively small quantities.

7.3.2.1 Aqua Ammonia The accidental spillage of aqueous solutions of ammonia could result in the emission of ammonia vapors that are irritating to S the-eyes and lungs of the personnel exposed. Ammonia vapor in l ,,i the air has explosive limits of 16 to 25 percent ammonia by volume. However, these concentrations are seldom encountered in the handling of ammonia; accordingly, the relative fire and explosion hazards are small.

/~'s

(_j 7.3.2.2 Hydrazine Hydrazine is a toxic, colorless, fuming, oily liquid with an

( odor resembling that of ammonia. It is a reactive reducing i agent that is used to remove residual oxygen from the

( (~) condensate and auxiliary boiler feedwater. If the hydrazine

! V l _

7.3-1 l

VEGP-OLSER-7 h tank were to leak, the leak would be contained in the diked area around the tank to prevent spillage. Consequently, the hazard to the environment is minimal.

7.3.2.3 Fuel Oil Diesel fuel oil is stored in tanks at several locations in buildings and the yard area. In all cases, except for automotive use (see' paragraph 7.3.2.4), the tanks have curbs -

high enough to contain the entire contents of the tank. Should an oil fire occur, sulfur dioxide, carbon monoxide, hydrocarbons, nitrogen oxides, and particulates would be emitted into the air until the fire is extinguished. The environmental impact of such a fire would be similar to that caused by any typical small oil fire and would result in a short term, localized degradation of the ambient air quality.

7.3.2.4 Gasoline Gasoline and diesel fuel to be used in automobiles is stored underground in compliance with the Environmental Protection Agency regulations for spill prevantion control and h countermeasure plans.

7.3.2.5 Tyrbine Lube oil Turbine lube oil is stored in tanks adjacent to the turbine building for each unit. Provisions such as curbs and an oil separator on the floor drain prevent this oil from leaking to the environment. The environmental impact of a fire would be the same as for fuel oil.

7.3.3 CHLORINE GAS RELEASE 7.3.3.1 Mode of Chlorine Gas Release As indicated in table 7.3-1, chlorine is stored at various locations onsite in either 1-ton or 150-pound cylinders. These cylinders could fail in two possible modes and release their chlorine contents to the environment. The first mode is the rupture of the cylinder. In this case, approximately 20 percent of the chlorine content is released instantaneously to the atmosphere and the remainder would evaporate. Such an

, occurrence is highly improbable due to the construction of the cylinders and the relief valves provided on each cylinder to prevent overpressurization. Therefore, this release mode was .

not considered in the environmental impact assessment of a chlorine release.

I) v VEGP-OLSER-7A Additional economic impacts that can ba monetized include costs of decontamination of the facility itself and the costs of cm replacement power. Probability distributions for these impacts have not been calculated, but they are included in the discussion

7A.4 RELEASES TO GROUNDWATER I ) 7A.

4.1 INTRODUCTION

This section presents a comparative evaluation of the radiological consequences which might result following a large release of radionuclides from the VEGP Units 1 and 2 reactors to the local groundwater system. Such releases could occur following a postulated core meltdown with eventual penetration of the containment basemat. Core debris which exits the melt hole

, at el 134 ft would then enter below the water table, which extends from el 134 ft to el 160 ft, and radionuclides in the debris would be leached into the groundwater system. It is also possible far containment sump water, which would be rich in dissolved fission products, to be released via the basemat melt

(, s hole into the groundwater system.

Li An analysis of the potential consequences of such an event is presented by the NRC staff in NUREG-0440, " Liquid Pathway Generic Study" (LPGS). It is this generic report which provides the y basis for the comparative evaluation of the VEGP units.

The LPGS presents analyses for a four-loop Westinghouse Phil located at a number of land sites. Two of the land-based sites analyzed in the LPGS were a river site on the Clinch River and an east coast estuary site. The Vogtle site is located 151 river miles from the Atlantic Ocean. The Vogtle site is most comparable to the river site except that the river is not long and there are no

,r w dams between the site and the ocean. VEGP is unlike the estuary y) site because it is far enough away from the ocean so that no tidal effects are present.

In the LPGS, parameters for each generic site were chosen to be representative of the full spectrum of similar sites. Parameters r~s used for analysis in the LPGS, although typical, do not represent

( ,)

~~

any actual plant site. The LPGS concluded that the individual and population doses for the liquid pathways would be fractions of the airborne pathways dose which could result from a core meltdown accident.

,s Individual and population loses are reported in the LPGS for the

( ', principal liquid pathways: drinking water, aquatic food, and direct exposure from swimming and shoreline usage. Exposure resulting from crop irrigation was also considered but was found ,

to contribute insignificantly to dose.

7A-9 Amend. 1 2/84

VEGP-OLSER-7A llh Doses to individuals and populations were calculated in the LPGS without taking credit for possible interdiction methods such as isolation of contaminated groundwater, the temporary restriction of fishing or providing alternate sources of drinking water (or additional purification equipment). Such interdiction methods would be highly successful in preventing exposure to radioactivity and the liquid pathways consequences would therefore be economic and societal rather than radiological.

7A.4.2 METHOD OF COMPARISON lh The estimate of the liquid pathways consequences resulting from a radionuclide release at VEGP is developed by comparing, in a ceries of ratios, the principal parameters applicable to the VEGP site to the parameter values used for the generic river site calculations in the LPGS.

The parameters for which ratio comparisons are developed are the following:

A. The radionuclide source released to the river.

B. The population along the river system which obcains drinking water from the river. 1 g

l C. The annual fish harvest on the river system.

l D. The annual recreational usage of the river system.

In a very general way the consequences of a major radionuclide release to the groundwater system at VEGP can be expressed as follows:

VEGP source LGPS dose for usage ratio for VEGP dose =

LPGS source the ith pathway the ith pathway Pathway " usage" ratios are the following:

O A. Drinking water population for VEGP river system Drinking water population for LPGS river system B. Annual fish harvest for VEGP river system Annual fish harvest for LPGS river system C. Manhours direct exposure for VEGP river system Manhours direct exposure for LPGS river system To be exact, this summation should be carried out for each h radionuclide. However, it has been found that the liquid pathway doses tend to be dominated by a very few radionuclides. As will ,

be shown in a subsequent section, the characteristics of the VEGP 7A-lO Amend. 1 2/84

I\

LJ VEGP-OLSER-7A site are such that most of the important radionuclides will undergo substantial decay during the process of groundwater transport to the Savannah River. Therefore, the general equation

(~~)

above provides an adequate approach to developing a comparative

. liquid pathways dose evaluation.

7A.4.3 SITE CHARACTERISTICS 7~s The VEGP is located on the southwest bank of the Savannah River at approximately river mile 151. This location is about 26 air

('-) miles south-southeast of Augusta, Georgia. The two-unit Westinghouse supplied PWR facility is located on the eastern margin of the Tifton Upland topographic belt, an elevated area of the Coastal Plain geographic region at a ground el 220 ft above

- sea level. The Savannah River cuts a deep, transverse valley through the Coastal Plain along the eastern border of the plant site, The river valley is a mature topographic feature with a broad flood plain at approximate el 85 ft. The plant is located about 3600 ft from the Savannah River at its clostst approach to the site.

The principle load bearing structure for plant Vogtle is the Blue t 4 Bluff Marl member of the Lisbon formation. The Blue Bluff Marl

(_) is a clayey marl approximately 70 ft thick; the top of the load 1 bearing horizon is located about 85 ft below grade at el 134 ft.

The containment building and most other plant structures are built upon this soil structure. The Blue Bluff Marl consists of a semiconsolidated glauconitic marl with subordinate lenses of dense, well-indurated, well-cemented limestone. The marl layer overlies the unnamed sands member of the Lisbon formation. The permeability of the marl layer is very low, essentially zero, and it is classified as an aquaclude. The marl effectively confines ground water within the unnamed sands to produce artecian conditions at the site. This artesian water region is referred to as the Tertiary Groundwater System and is the source of the ey Plant Vogtle potable water. Due tc the impermeable nature of the j (

) marl, recharge to this aquifer is not a direct result of rainwater infiltration at the site.

The influx of meteoric water at the plant site and surrounding area, after percolating through the overlying soil, accumulates

. .w above the Blue Bluff marl to produce water table conditions.

i

) This water table aquifer extends from el 160 ft to the top of the Blue Bluff marl at el 134 ft. Hydraulic connection with the Savannah River is precluded by the stratigraphy of the site.

The Blue Bluff Marl formation slopes in a general easterly trend f3 toward the Savannah River. However, this trend is insufficient

) for the marl to pass beneath the river. As the Savannah River cut its channel the marl was exposed at el 130 ft on the south-west bank of the river approximately 45 ft above the flood plain. ,

7A-ll Amend. 1 2/84

, .o VEGP-OLSER-7A h The water table aquifer discharges to the surface by seepage through the flanks of adjacent stream beds as th2y flow toward the Savannah River. The water table also dischargus to surface waters in several free-flowing springs located near the plant site, These springs feed small streams which flow eventually to the Savannah River. The local groundwater system is shown in FSAR figure 2.4.12-7 and is described in section 2.4.12.2.

7A.4.4 GRGUNDWATER TRAVEL TIME Radionuclides entering the groundwater system would be entrained in the natural groundwater flaw to streams feeding into the Savannah River. A calculation of the travel time for an accidental spill of radioactive material is presented in section 2.4.13.1 of the VEGP FSAR. This analysis was performed for a rupture in a conveyance line from the waste monitor tank. The shortest path from the assumed spill point to a stream channel

, was toward Mathes Pond, a distance of 2500 to 2700 ft. From the midpoint of VEGP Unit 1 the distance to the nearest stream is approximately 3000 I'c in a northeasterly direction (see figure 2.4.12-7, sheer 1 of the VEGP FSAR). It is assumed that the soil in this direction has the same properties as the soil in the direction of Mathes Pond. The porosity of the sandy soil was estimated to be 45 percent.

porosity. lll Over the first 1600 ft of the flow path the groundwater drops 6 ft giving a hydraulic gradient of 3.8 x 10-2 Over the last 1400 ft of the flow path the groundwater drops 30 ft giving a hydraulic gradient of 2.1 x 10-2 . The increase in the hydraulic gradient implies a lower permeability. From the range lll of permeability determinations (200 to 250 ft/ year from field measurements and 10 to 20,000 ft/ year from laboratory measurements), conservative values of 8000 ft/ year and 200 ft/ year were used for the spill analysis. Since the hydraulic gradients in this case are close to the values used in the spill analysis, the same values can be used for the permeabilities to lll give our "best estimate" travel time. Over the first part of the path, the seepage velocity (vi) is given by: -

BE = 67.56 ft/ year 9.33 ft/ year As an added conservatism we will assume that the permeability remains constant at 2000 ft/ year over the entire flowpath. Then the " ultra-conservative" value of the seepage velocity over the second part of the path (v2 2) is given by:

l a _ (8000 f t/ year)(2.1 x 10 -2) y = 373.3 ft/ year

The " ultra conservative" groundwater transport time (GWTT) is given by:

(s/ ) e The core radionuclide inventory.

e The fractior: of the core radionuclide inventory released to groundwater via such mechanisms as sump water release and leaching from the core debris.

\/ e The attenuation which takes place during transport through the groundwater system, principally from radioactive decay and adsorption.

VEGP-OLSTR-7A lh The LPGS analyses are based on the core inventory for a four-loop Westinghouse PWR similar to the VEGP units. The fraction of the core inventory which could be released to the groundwater depends on numerous factors, such as the specific accident sequence and containment failure mode, containment sump structure, and the nature of the soils which separate the containment basemat from the underlying groundwater system. For convenience, it is assumed that the LPGS assumptions apply to the VEGP units. A number of release cases are considered in the LPGS; however, the worst cases considered (instantaneous release of all sumpwater and all activity available for leaching) '" are clearly bounding for any plant-site combination.

The fraction of each radionuclide source released into the groundwater which eventually enters the Savannah River depends on the velocity of groundwater movement as well as retardation of radionuclide travel caused by adsorption on the aquifer soils.

The relationship between groundwater velocity (or groundwater trcnsport time), radionuclide adsorption, and the radionuclide fraction which is ultimately transmitted without decay is given by the following expression: '"'"

In (T.F.) = - 0.693 (GWTT)(a) , where T 1 T.F. = transmitted fraction.

GWTT = groundwater transport time.

T = radionuclide half-life, a = adsorption retention factor.

The adsorption retention factor is equal to (1 + p/n Kd) where:

p = bulk density of the aquifer media.

n = porosity of the aquifer.

Kd = ofdistribution coefficient which is defined as the mass O

radionuclide adsorbed per gram of soil divided by the mass of radionuclide dissolved per milliliter of groundwater.

A typical value of the ratio p/n is 5; however, for consistency the value of 4.1 used in the LPGS is adopted here as well. ' 2" llh O

In the Sandia liquid pathway study, Kd values of 20 and 200 were used for Sr-90 Cs-137, respectively.'2" Duke Power Company estimated Kd values of 560 (Cs-137) and 6 (Sr-90) for the fractured bedrock underlying its Catawba Nuclear Station.82" Kd values of 5 (Sr-90) and 50 (Cs-137) were estimated to

  • VEGP-OLSER-7A lh used in the LPGS the transmitted fractions for the principal radionuclides are as follows:

(LPGS) h H3 12.1 -1.57 0.21 0.22 Sr-90 28 -6.24 0.002 0.002 Ru-106 1 -19.0 0 0 h Cs-137 3 -52.5 0 0 The effect of the much longer GWTT at the VEGP site (27.4 years compared to 0.61 years in the LPGS), even with the relatively small assumed values of Kd, is very significant. Virtually no Cs-137 or Ru-106 would be expected to reach the Savannah River.

Only 2/1000 ef the released Sr-90 would reach the river (compared to a transmitted fraction of 0.87 in the LPGS).

Tritium is closer to the LPGS results with a transmitted fraction of 0.21 for VEGP compared to 0.97.

The source effect on liquid pathway consequences can be 1 summarized as follows:

A. Pathway doses which are dominated by Cs-137 and/or Ru-106 will be nil in comparison to doses calculated in the LPGS.

B. Pathways doses which are dominated by Sr-90 will be about 3 orders of magnitude lower than those calculated in the LPGS, assuming equal pathways exposure.

C. Pathways doses from H 3 will be lower but w.4 thin the same order of magnitude, assuming equal pathways exposure. At the levels of population dose calculated in both NUREG-0440 and in the Sandia study '"),

tritium is not a significant contributor. This is in part due to the smaller core inventory of tritium (two to three orders of magnitude less the curie content than Sr-90, Cs-137, or Ru-106)'1" and also in part to the relatively low total body dose factor (1 x 102 g man-rem / curie compared to 1.9 x 10' man / rem / curie for W Sr-90 and 8 x 10" man-rem / curie for Cs-137 ) .

. %I from the Savannah River is 70,000. This is only 11.3 percent of the number used in the LPGS. In addition the drinking water

,- pathway dose is dominated by Sr-90 and Cs-137.<2" Since the

( ) transmitted fractions of these radionuclides are much smaller than the LPGS, the drinking water pathway dose for VEGP is about 4 orders of magnitude less than the LPGS dosa.

7A.4.7 FISH FLESH PATHWAY COMPARISON Il In the LPGS it is estimated that the annual fish harvest for the generic river system is 1.2 x 105 kg (7.7 x 105 kg recreational and 3.9 x 105 kg commercial) . ' 2 " The annual recreational fish harvest on the Savannah River from 0 to 187.2 miles for 1980 is shown in table 2.1-42 as 1.04 x 10' kg. The commercial fish harvest is not complete but the mean commercial shad harvest is shown in table 2.1-43 as 3.7 x 10' kg. The amount of fish harvested from the Savannah River is probably roughly equivalent to the LPGS generic river.

Like the drinking water pathway, the fish flesh pathway is dominated by Sr-90 and Cs-137.<2" Since the Cs-137 source is three orders of magnitude lower, it is concluded that the fish

/'^') flesh dose is about three orders of magnitude lower. In

(_/ addition, the economic and societal impacts of a severe accident 1 on ocean fish catch should be roughly three orders of magnitude less than that assessed for the LPGS ocean fish catch.

7A.4.8 SHORELINE AND IMMERSION PATHWAY COMPARISON The shoreline and immersian pathway includes st.ch activities as swimming, wading, sunbathing, etc. These are external exposure pathways and dosage is dominated by Ru-106, Cs-137, and Co-60. ' 2 " For the VEGP site with a groundwater travel time of 27.4 years and assuming that Kd for Co-60 is 75, the transmitted fraction is extremely small, as has already been

,c3 shown to be the case for Cs-137 and Ru-106. It is therefore l

)

concluded that the direct exposure dose would be nil in comparison to those calculated in the LPGS.

4.9 CONCLUSION

S s On the basis of VEGP site features and the specific comparisons

) of radionuclide source and pathway populations, it is apparent that the spectrum of liquid pathways doses following a Class 9 accident would be much lower for VEGP than the doses calculated in the LPGS for a river-sited plant.

7~s This is mainly due to the much smaller source released to the

() Savannah River, which in turn results mainly from a much longer groundwater transport time. If shorter times are postulated, 7A-17 Amend. 1 2/84

VEGP-OLSER-7A llh the adverse effect would be small and would probably be offset through the assumption of more realistic distribution coefficient (K d) and permeability coefficient (k) values.

Il the extreme, if one were to postulate the same radionuclide O

source as in the LPGS, the pathways doses would still be slightly lower, since the pathways population ratios are about the same or lower.

7A.5 RISK CONSIDERATIONS The foregoing discussions have dealt with both the frequency (or likelihood of occurrence) of accidents and their impacts or consequences. Since the ranges of both factors are quite broad, it is also useful to combine them to obtain average measures of environmental risk. Such averages can be particularly instructive as an aid to the comparison of radiological risks associated with accident release 9 and with normal operational releases.

A common way in which this combination of factors is used to estimate risk is to multiply the probabilities by the consequences. The resultant risk is then expressed as a number of consequences expected per unit of time. Such a quantification g

of risk does not at all mean that there is universal agreement that peoples' attitudes toward risk, or what constitutes an acceptable risk, can or should be governed solely by such a measure. At best, it can be a contributing factor to a risk judgment but not necessarily a decisive factor.

Table 7A-3 shows average values of risk associated with population dose, acute fatalities, latent fatalities, and costs for evacuation and other protective actions. These average values are obtained by summing the probabilities multiplied by the consequences over the entire range of distributions. Since the probabilities are on a per-reactor-year basis, the averages shown are also on a per-reactor-year basis.

The population exposures and latent cancer fatality risks for VEGP are comparable to the values calculated in NUREG 0490, 0534, 0775, and 0779 for various plants, which showed that accident risks are comparable to those for normal operation.

There are no acute fatality nor economic risks associated with protective actions and decontamination for normal releasee; therefore, these risks are unique for accidents. For perspective and understanding of the meaning of the acute fatality risk of 0.OOOOO22/ year, however, we note that, within a close approximation, the population at risk is that within about 10 miles of the plant, about 15,500 in the year 2007. Accidental 7A-18 Amend. 1 2/84 J

() VEGP-OLSER-7A fatalities per year for a population of this size, based upon -

overall averages for the United States, are approximately 1.0 from motor vehicle accidents, 0.28 from falls, 0.12 from

()

- _s drowning, 0.11 from burns, and 0.046 from firearms (page 577 of

. reference 22).

There are other economic impacts and risks that can be monetized that are not included in the cost calculations discussed in

- section 7A-3. These are accident impacts on the facility itself

('-,) that result in added costs to the public, i.e., ratepayers, taxpayers, and/or shareholders. These are costs associated with decontamination of che facility itself and costs for replacement power.

. No detailed methodology has been developed for estimating the contribution to economic risk to Georgia Power Company associated with cleanup and decontamination of a nuclear power plant that

. has undergone a serious accident toward either a decommissioning or a resumption of operation. Experience with such costs is currently being accumulated as a result of the Three Mile Island accident. It is already clear, however,.that such costs can

! approach or even exceed the original capital cost of such a

("] facility.

V In addition to damage to or loss of the facility resulting from accidents, the other major additional cost is that of replacement power. These costs are affected by the point in the lifetime of

the plant at which an accident might occur. The present worth cost is highest for an accident occuring at the beginning of the plant operating life and decreasing over the plant life. It is l assumed for these calculations that one unit of VEGP is i permanently lost and replaced by new capacity after 8 years and l that the undamaged unit is shutdown for 3 years before restart.

For illustrative purposes, the costs and economic risk have been estimated for a " worst case" situation for the 2200-MW (electric) f~ VEGP station by postulating a total loss of one of the units in l -( )

the first' year of a projected 40-year operating life. Net replacement power cost of 20 mills /kWh is assumed. Using a 60 i percent capacity factor, the annual cost of replacement power would be $231 million for the two units in 1980 dollars. The additional capital costs as a result of having to construct a new f3 facility are $67 million/ year, again in 1980 dollsrs (see NUREG

() 0775).

If the probability of sustaining a total loss of the original facility is taken as the probability of the occurrence of a core

melt accident (approximated by the sum of probabilities for the j3 accident sequences and release categories in table 7A-1, i.e.,

- ( ). about 4.8 chances in 100,000 per year), then the average contribution to economic risk that would result from a loss early in the operating life of a VEGP unit is about $15,000 for each of _.

1 l 7A-19

VEGP-OLSER-7A h the first 3 years until the undamaged plant is returned to service, then $9100/ year until the damaged unit is replaced, and

$3300/ year additional capital costs for the assumed remainir.; 32 years of plant service. A worse situation not evaluated here is one where the plant must be decontaminated for safety reasons but is not put back in operation. A new plant then has to be built.

Decontamination cost in that case, however, should be somewhat less than the case where the plant is made suitable for operation (see NUREG 0775).

7A.6 UNCERTAINTIES l1 The foregoing probabilistic and risk assessment discussion has been based upon the methodology presented in the RSS which was published in 1975.

In July 1977, the NRC organized an Independent Risk Assessment

. Review Group to: clarify the achievements and limitations of the RSS; assess the peer comments thereon and the responses to the comments; study the current state of such risk assessment methodology; and recommend to the NRC how and whether such methodology can be used in the regulatory and licensing process.

The results of this study were issued September 1978. This report, called the Lewis Report, contains several findings and lll recommendations concerning the RSS. Some of the more significant findings are summarized below.

A. A number of sources both conservative and nonconservative in the probability calculations in RSS were found to be very difficult to balance. The review group was unable to determine whether the overall probability of a core melt given in the RSS was high or 1ca, but they did conclude that the error bands were understated.

B. The methodology, which was an important advance over earlier methodologies that had been applied to reactor risk, was sound.

C. It is very difficult to follow the detailed thread of calculations through the RSS. In particular, the executive summary is a poor description of the contents 3 of the report, should not be used as such, and has lent W itself to misuse in the discussion of reactor risk.

On January 19, 1979, the NRC issued a statement of policy concerning the RSS and the review group report. The NRC accepted the findings of the review group.

The accident at Three Mile Island occurred in March 1979, at a time when the accumulated experience record was about 400 _

reactor-years. It is of interest to note that this was within 7A-20 Amend. 1 2/84

i

() VEGP-OLSER-7A the range of frequencies estimated by the RSS for an accident of -

this severity (page 553 of reference 22). The action plan of

,x NUREG 0660" presents a sequence of actions, some already

('-') taken, that may result in a gradually increasing improvement in safety as individual actions are completed. The improvement in safety from these actions has not been quantified, however, and the radiological risk of accidents discussed in this chapter does not reflect this improvement.

m 7A.7 CONCLUSIONS

(_) l1 Section 7.1 and this appendix consider the potential environmental impacts from accidents at the VEGP facility. These have covered a broad spectrum of possible accidental releases of radioactive materials into the environment. Included in the considerations are postulated design basis accidents and more severe accident sequences that lead to a severely damaged reactor core or core melt.

The environmental impacts that have been considered include -

potential radiation exposures to individuals and-to the population as a whole, the risk of near and long term adverse l

f,)

N-health effects that such exposures could entail, and the potential economic and societal consequences of accidental contamination of the environment. These impacts could be severe but the likelihood of their occurrence is judged to be very small. This conclusion is based on: the fact that considerable experience has been gained with the operation of similar facilities without significant degradation to the environment; and a probabilistic assessment of the risk based upon the methodology developed in the RSS. The overall assessment of environmental risk of accidents, assuming protSctive action, shows that it is roughly comparable to the risk from normal operation, although accidents have a potential for acute fatalities and economic costs that cannot arise from normal r^s operations. The risks of acute fatality from potential accidents

(,) at the site are small in comparison with risks of acute fatality l

from other human activities in a comparably sized population.

I We have concluded that there are no special or unique circumstances about the VEGP site and environs that would result in a greater environmental impact than those from other presently

, (^)s

(, operating pressurized water reactor (PWR) nuclear power plants.

VEGP-OLSER-8 lh 8.1.1.2 Energy Sales The territory served at retail by Georgia Power Company (GPC) and interspersed nonaffiliated electric distribution systems, which directly or indirectly receive most of their power requirements at wholesale from GPC, has an area of approximately 57,200 miles: and an estimated population, based on the 1980 census, of approximately 5,100,000. The industrial classifications from which GPC derives the majority of its industrial revenues include textile mill products, chemical and allied products, stone, clay and glass products, food and kindred products, paper and allied products, and government facilities served under an areawide General Services Administration contract (for example, military bases).

The VEGP will be co-owned by four separate electric systems within the State of Georgia. Georgia Power Company will own 45.7 percent of the plant, while 54.3 percent will be owned by l1 Oglethorpe Power Corporation, the Municipal Electric Authority of Georgia (MEAG), and the City of Dalton, each wholesale customers of GPC. Oglethorpe will own 30 percent of VEGP, MEAG will own 22.7 percent, and the City of Dalton will own 1.6 percent. In addition to its 45.7 percent share, GPC has l1 3 h agreements with Oglethorpe and MEAG for the repurchase of declining amounts of their owned capacity over an 8-year period beginning in the year of commercial operation of each unit of VEGP. These are referred to as buy-back agreements.

A. Retail The retail service area rights of all electric suppliers in the State of Georgia are regulated by the 1973 State Territorial Electric Service Act. Pursuant to the provisions of this act, all areas within existing municipal limits were assigned to the primary electric supplier therein on March 29, 1973 (451 to g GPC, including Atlanta, Columbus, Macon, Augusta, w '

Athens, o ome, and Valdosta; 115 to rural electric cooperatives; and 50 to publicly owned systems). Areas outside of such municipal limits were either to be assigned or to be declared open for customer choice of supplier by action of the Georgia Public Service Commission pursuant to, standards set forth in the act.

Although the commission has assigned substantial portions of the land area in the state to a supplier, the act provides that any new customer locating outside of 1973 municipal limits and having a connected demand in excess of 900 kW may receive electric service from the supplier of its choice. Retail sales during 1980 totaled 3.7 million kWh.

9-year period from 1987 through 1995. The cost projections are based on an average of projections for No. 2 fuul oil. No. 2

() fuel. oil is used in these projections because the majority of the oil-fired electric generating plants within the Southern electric system use this grade of fuel oil. On a present worth basis, in 1982 dollars and using a factor of 10 percent, the value of reduced oil consumption for the period 1987 through 1995 is approximately $200 million.

8.1.2.4 Displacement of Air Pollutants The operation of VEGP will displace generation that would otherwise be made from fossil fuel boilers. This will result in displacement of air pollutants that would be emitted from fossil fuel generation. Assuming an annual generation capacity of 1.2 x 10" kWh for a 1971 to 1978 design coal-fired boiler of approximately 10,000 Btu /kWh, the annual savings in air pollutants would be 1.2 x 107 lb particulate, 2.57 x 10' lb SO,, and 8.4 x 10' lb of NO g.

8.1.2.5 Employee Recreation Area There will be an employee recreation area located near the VEGP. The recreation area will be approximately 2 miles southwest from the plant site. It will. consist of 125 acres of 1 land, of which 50 acres will be developed. The recreation

facilities include a softball field, tennis court, small pond, l

overnight camping, and picnic area.

The VEGP site is centered in wooded lands scattered with fields used'for agriculture. The terrain is very flat. The clearing of the site for the VEGP required the removal of several hundred acres of trees and brush. No significant harm was done to existing landscape, rock formations, lakes, rivers, etc. >

At the time of purchase, approximately 721 acres of the site were croplands, pastures, and fields. Except for two small ponds,.the rest of the 3169-acre site.was in timber.

Construction of the plant facilities requires approximately 1399 acres of the site for the main power block and cooling towers, construction facilities.snd stockpile, the river intake -

~

facility, construction debris-basins, meteorology tower and 1 access road, and roadways. After construction of the plant is completed, the 519.6. acres used.for construction activities will be, landscaped. The use of 717-acres for general plant L facilities (buildings, roads, parking lots, and other ,

' facilities) will continue throughout the life of the plant and  !

Areas in the vicinity of VEGP are rich in both prehistoric and historic cultural resources. Since none of the properties are g near the site, they will not be adversely affected by plant operation.

Natural draft and nuclear service (mechanical draft) coo,ing towers will be used at VEGP. The operation of these towers is not expected to cause increased frequency of ground fog, reduced g visibility, icing, or any other adverse meteorological conditions (see section 5.1). Effects of increased noise levels resulting from the operation of the VEGP are discussed in section 5,6.

A study prepared for Georgia Power Company by Battelle Columbus Division estimated the impacts of the VEGP on essential community services in surrounding areas.

SUMMARY

O This. chapter provides a summary of those licenses, permits, and approvals required by federal, state, local, and regional authorities for station and transmission system construction and operation. This chapter also contains a listing of the state environmental. agencies, regional' representatives, and local

() authorities which were contacted concerning the station location and construction. The status of obtaining all required l

approvals is indicated.  ;

12.1.1- STATUS OF STATION ENVIRONMENTAL APPROVALS AND CONSULTATIONS

The information concerning status of the station's environmental approvals and consultations is listed in tables 12.1-1, 12.1-2, and 12.1-3. Table 12.1-1 lista permits, certifications, and
approvals dealing with water quality during the construction and operation of the facility. Air quality permits required to construct and operate the facility are listed in table 12.1-2.

i . Table 12.1-3 lists the general permits, notifications, and plans

~\ ,

required to construct and operate the facility.

12.1.2- STATUS OF TRANSMISSION SYSTEM ENVIRONMENTAL APPROVALS AND CONSULTATIONS The information concerning status of the transmission system

j. environmental approvals and consultations is listed in table L -12.1.4. Application for these permits are made as transmission i system: routes are finalized. Most of the permits required for i the VEGP-Wadley 500 kV line have been issued. Other permit j applications'are pending. In addition, the Georgia Department of Natural Resources State Historic: Preservation Officer was supplied with a cultural resource management pla:. for the

-_VEGP-Wadley.line (J. J. Shive letter to E. A. Lyon, September 7, Os 1982). The-plan outlined Georgia Power Company's (GPC) procedures for identifying and assessing the significance of cultural resources within the transmission corridor. The plan also outlined mitigative actions to be taken by GPC should the f~e cultural resource inventory identify any significant sites.

I N. 12.1.3 CONSULTATIONS WITH STATE, LOCAL, AND REGIONAL PLANNING AUTHORITIES Georgia Power Company (GPC) has consulted with the following L' groups concerning the VEGP. (See Construction Permit Stage l t Environmental Report (CPSER), chapter 12.)

VEGP-OLSER-Q Question E290.3 (OLSER 3.6.4.2) .

Although in Final Environmental Statement - Construction Permit l'V (FES-CP) section.5.5.1.1 the conclusion is that salt drift emissions would be negligible, the predicted quantity of drift of approximately 305 lbs/ acre / year (Construction Permit Stage

_ Environmental Report (CPSER) 5.3.2) (acsuming two-unit operation) within a mile radius of the cooling towers is presently considered to be in the range of potential damage to

vegetation. As such, indicate the plant community types that

~[ ']' . -will be impacted by drift. Also, a. monitoring program for

. detection of possible detrimental effects of drift on vegetation will be required.

3

Response

The predicted salt drift deposition rate cited in section 5.3.2 of the CPSER, has been reevaluated based on current design parameters and expected operating conditions._ (Refer to the response to question E451.17.) It~is estimated that the

-~ deposition rate outside.the site boundary would be at or below

[ N the vegetation damage threshold level cited in Nuclear Regulatory Commission (NRC) Regulatory Guide 4.11. In Lf( )-

l"' addition,- the only significant chemical constituent in the Leooling tower-drift is total dissolved solids (TDS); no toxic

~

elements or compounds.are present. Therefore, as stated in the FES-CP,--the effect of the predicted salt deposition rate at VEGP

-on the surrounding terrestrial' environment is expected to be negligible.

Results of vegetation monitoring studies at various nuclear L power plants in the eastern and southern regions of the United States indicate no adverse impact to the surrounding vegetation as a result of salt drift. It should be noted that several of

~these plants have significantly higher deposition rates than

'  :( ). those-predicted for VEGP. Similarly, field experiments on agricultural crops at Chalk' Point show no effect on yield and no

leaf damage at. deposition rates four times greater than those
predicted for-VEGP.

. The dominant vegetation at VEGP is upland with hardwood pine and L ;[3-). . scattered agricultural fields. The. plant community types within 1 mile of the cooling towers include: reclaimed deposition ,

areas,. sand hill-upland hardwood-pine, sand hill-upland hardwood -

l , planted slash pine, branch hardwoods, cove hardwoods, slash pine ,

. plantation, . bluff hardwood, bottomland hardwood, sand hill-longleaf pine, cleared sandhills, and old fields. This

'(' )

H terrestrial environment is representative of several of the

.other surveyed power plants, which reported even higher salt l deposition rates and no. vegetation damage. Therefore, cooling 2 QE290.3-1 Amend. 1 2/84

VEGP-OLSER-Q h tower drift is not expected to result in leaf injury or reduced yields to local crops and native vegetation.

From the above, it can be concluded that the effect of cooling h tower drift on the terrestrial environment at VEGP is negligible and an operational monitoring program is not deemed necessary.

Surface water quality in the VEGP vicinity is influenced primarily by industrial and municipal waste water discharges

into the Savannah River in the Augusta area; heat and waste water discharge from the Savannah River Plant, and agricultural runoff from farmlands around the-site. According to the following references, pollution sources are Columbia Nitrogen, Olin Corporation Kimberly-Clark, textile mills, municipal sewage treatment plants in Augusta and South Carolina, J. P. Stevens Mill, Valchem Chemical, and the Savannah River ~ Plant. In the vicinity of the VEGP, there are no other known environmental ~

Question E291.6 (OLSER 3.3)

Describe the potential for short circuiting of makeup water to (3j the circulating water system to the blowdown line in the cooling tower basins.

-Response

()

p The potential of river water makeup "short circuiting" to the blowdown outlet of the cooling tower basin does not exist due to inherent cooling tower design features including:

A. The linear distance between the river water makeup line discharge into the cooling tower basin and the basin blowdown outlet is 200 ft for the Unit 2 tower and much greater for the Unit 1 tower.

B. The cooling tower basin water volume will normally average well over 6 million gal / tower. This volume will not be affected by the average flows of either 20,000 gpm makeup / tower or 5000 gpm blowdown / tower.

The entrance velocity to the blowdown outlet is less

-(~}'

s- than 4 fps.

C. The cooling tower basin slab is continuously sloped towards the cooling tower center.

D. Makeup water temperature closely approximates cooling tower basin water temperature. During winter operations, makeup water may be much colder but only local, rapidly dissipating temperature inversions would form having no effect on overall basin water temperature.

jc In conclusion, it is most unlikely that makeup water will enter t the basin and directly proceed to the blowdown outlet.

Tables 8.1-5 and 8.1-6 of the OLSER indicate that the applicant projects capacity factors ranging from 59 percent to 82 percent

((_/} during.the 7-year period beginning in 1987. The staff's view is that average annual capacity factors on the order of 55 to 60 percent are reasonable for a nuclear generating unit over its operating life. Further, during the period of maturation

, -(generally the first 5 years of operation), capacity factors i

tend to be less than lifetime average capacity factors. Please

.(~}

s-- provide justification for the higher capacity factors used in your OLSER analysis.

Response

The capacity factor for a nuclee.r unit on the Southern electric system is projected to be equivalent to its availability. This is due to the economics of operation and the small percentage of total Southern electric system capacity that they comprise. The availability / capacity factor is calculated as (1-MOR)*(1-EFOR)

(effective forced outage rate and maintenance outage rate). .A September 1982 unit operating analysis study,

-s performed by the Generation Planning Department of Southern Company Services provided EFOR and MOR for use in 1983 planning studies. The results of the study yielded an 18.4 percent EFOR and 21.2 percent MOR for nuclear units. Since a unit cannot have an EFOR when on scheduled outage, the effective availability / capacity factor becomes 64.3 percent.

(1-MOR) * (1-EFOR) = availability / capacity factor Since we assume a yearly alternating maintenance cycle of 10 l

weeks, then.12 weeks and a constant EFOR of 18.4 percent, an alternating capacity factor of 66 percent /63 percent is produced by the same type calculation. The following discussion provides

()

\-/

the basis for the EFOR and MOR projected by the Operating Analysis Study and utilized in the production cost analysis and in table 8.1-5 and table 8.1-6 of the VEGP-OLSER.

EFOR

[~\

\- '

Industry data provided by the National Electric Reliability Council (NERC) in the publication, " Ten Year Review 1971-1980, Report on Equipment Availability," projects a nuclear EFOR of .

174 6 percent. However, experience on nuclear units presently operating on the Southern electric system were slightly above l ~

this average and a value between the NERC and Southern electric system historical average was recommended as appropriate. This

VEGP-OLSER-Q MOR For scheduled outage rates Nuclear Regulatory Commission (NRC) data was combined with data from NERC and Southern electric syst.em (SES) historical data to recommend a maintenance cycle. lh NERC data for 1978 - 1979 yielded a rate of 9.8 weeks / year and a 1980 rate of 12.31 weeks / year; SES historical data for the past 5 years was 14.02 weeks / year, falling to a 12.58 weeks / year average over the past 2 years; and NRC data calculated to 10.99, 12.60, and 10.12 weeks / year for the years 1979 - 1981, respectively. Considering the historical data, it was lh recommended that a cycle of 12-10-12-10 weeks / year with an average of 11 weeks / year be used for maintenance or scheduled outages.

Other Considerations The exception to the 63 percent capacity factor or rationalization of the 82 percent capacity factor demonstrated by VEGP Unit 2 in 1988 is that VEGP Unit 2 is scheduled to go commercial in September 1988, and since no maintenance is scheduled for the remainder of 1988, the availability is simply 1-EFOR or 82 percent.

Question E450.1 (OLSER Appendix 7.A)

It is stated that external events have not been considered.

Discuss the dominant likely external events that would be h'_)T considered in the probabilistic assessment of severe accidents if they were considered. For each of these dominant external events, discuss the safety-related systems, structures, and components most vulnerable to damage from the particular event.

(]_/ Response External events (seismic, tornado, fire, flood, etc.) have been considered in previous probabilistic safety studies. Most of

- the studies have estimated that core melt scenarios initiated by external events are not dominant contributors to total risk.

The Zion Probabilistic Safety Study had seismic events as a dominant contributor to risk. Eut the study states on page 7.2-11 that almost all the calculated frequency of seismic melt results from the uncertainties in the fragility curves. Thus, l the melt frequency results from the interaction of the tails of i the seismicity and fragility distributions.

()

VEGP Units 1 and 2 have been designed to comply with the Standard Review Plan design criteria for wind and tornadoes, floods,. missiles, seismic events, and fires except for the points enumerated in section 1.8 of the Final Safety Analysis Report (FSAR). The plant is designed with substantial margfns of safety for the above external events as described in sections 3.3, 3.4, 3.5, 3.7, and appendix 9A in the FSAR. Extra margins of safety are taken for safety-related equipment to ensure safe shutdown if the external event causes any threat to safe operation of the plants.

-meteorological data (i.e., no missing data) is used in evaluating the environmental impact of postulated accidents through a probabilistic risk assessment such as that described

'in appendix 7A of the OLSER. The staff performs an independent evaluation using the computer code CRAC (calculation of reactor accident consequences).

Response

.The first period of record for the meteorological data is December-4, 1972 to December 4, 1973.

Meteorological data was collected continuously from mid-1972 through 1973. The best 1-year period of onsite metsorological data (December 1972 to December 1973) was chosen for inclusion in the Preliminary Safety Analysis Report (PSAR). In April 1977 the meteorological program was restarted. All instrumentation used previously was installed at the same location as before.

Two years of data (April 1977 to April 1979) with data recovery of greater than 90 percent was collected and used with the first period of data (December 1972 to December 1973) in the FSAR.

VEGP-OLSER-Q data from the Savannah River Laboratory also showed a very high frequency of extremely unstable conditions. The joint frequency tables provided are classified per Regulatory Guide 1.23.

The meteorological tower at the VEGP site is located in a O cleared area approximately 5000 ft SSW of the main plant structures. Thus, tower measurements are not influenced by plant structures. All temperature sensors are aspirated and are oriented down and towards the north per good engineering practice (World Meteorological Organization, Publication No. 8, Technical Paper No. 3, chapter 4, section 4.2). The area near the tower is covered mostly by low weeds with some short scrub oak and pine trees and is characteristic or the plant environs.

Question E451.5 (Regulatory' Guide 4.2, section 2.3 and Safety Review Plan 2.3.2) (FSAR 2.3.2) 2 (/I Provide a comparison of monthly and annual precipitation amounts measured at the site with concurrent data from Augusta, Georgia and contrast these observations with the climatological normals for Augusta, Georgia presented in table 2.3.2-1 of the Final  !

Safety Analysis Report (FSAR). Also, provide a discussion of the difficulties in measurement of precipitation at the VEGP site "during the 1980-81 site year" (see page 2.3.2-4 of the

' -('.. '

FSAR). (The response to this question may affect the selection of the data set for the probabilistic risk assessment discussed

'in E451.2.')

Response (

A comparison of monthly and annual precipitation data in the VEGP-site. area was.done using the VEGP site and Augusta airport data as shown in table 451.5-1. On a month-by-month comparison some months compare quite well for the first 3 years of data.

The annual totals were.always lower at the.VEGP site. This is

~

(~%- probably due to several factors. First, the site's

, (_)

precipitation gage has a relatively small surface area for collection of precipitation. Also, there is no wind screen around the gage to minimize the effects of the wind. During the summer months, most of the precipitation comes from  ;

thunderstorms in the. site area, . characterized by short periods

.of high' wind speeds and heavy precipitation. This type of situation may result in less than representative rainfall collection in;the gage. All precipitation data from the l- weighing-type' rain gage were digitized from strip charts.

Precipitation charts are scaled from 0 to 10 in., with the

smallest increment on the chart being 0.1 in. It is possible to
digitize to 1/2 of an increment or 0.05 in. Therefore, some of

, . - - the-minor precipitation events (less than 0.05 in.) would not be included in the precipitation totals. This would also affect L

l '

_() .the number ~of days.in which precipitation occurred.

1 Variance between the 4 years of data is considerable. The first 2 years at Augusta are close to annual. normals. The last 2

-years are much below normal. Precipitation at the VEGP site is

progressively less each year in agreement with the Augusta 4( ).

^'

airport data. The differences in the amount of precipitation at

  • the two sites can be attributed to the reasons stated above as -'

well gas short periods when the site instrument was not-

. functional and precipitation' occurred. Data for 1980 to 1981 are clearly.not useable. Table 451.5-1 also shows the number of j

) days'with significant precipitation. LIn all cases the climatic normals are higher than the annual' totals for the year at AugustaLand Vogtle. _

QE451.5-1 Amend. 1 2/84

VEGP-OLSER-Q ll

Response

In summary, it would appear that the use of the VEGP site meteorological data for the probabilistic risk assessment discussed in E451.2 would result in an underestimate of the llh frequency of meteorological scenarios involving rain. If one assumes that Augusta measurements are representative and that the relation between number of hours with rainfall at Augusta and Vogtle is the same as the relation between the number of days of rainfall at the two sites, the underestimate of rainfall frequency could be as large as a factor of 2 to 3 (excluding ll 1980 to 1981). However, this does not translate directly to a similar bias in the risk distributions. Most of the risk measures are not strongly sensitive to wet deposition modeling or data. The early fatality distribution is sensitive to wet deposition modeling and data, but the censitivity is usually noticeable only in the high consequence-low frequency end of the distribution. Correction of the bias in the data might be expected to increase the frequency of early fatalities in the high consequence end of the distribution by a factor of 2 to 3 at most. Correction of the bias would not be expected to increase the maximum number of early fatalities calculated because the rain scenarios simulated using Vogtle data probably reasonably represent the spectrum of rain scenarios that could W

be simulated with inclusion of corrected data.

A copy of thin map and a site vegetation map was provided by D. O. Foster's letter to H. R. Denton dated February 10, 1984.

The site area is composed of gentle rolling hills and flat areas common to most river valleys. The only significant feature of

es the terrain is the river valley itself,.which is not expected to have any significant effect on the meteorological measurements.

The vegctation around the meteorological tower has been cleared

r VEGP-OLSER-Q Question E451.10 (Safety Review Plan 2.3.3) (FSAR 2.3.2) .

The't'chnique e for measuring vertical temperature gradient at the

'[') VEGP site is not clear from the information presented in table

\/. 2.3.2-2 of'the Final Safety Analysis Report (FSAR). Vertical temperature gradient is most often measured directly (e.g.,

- through a resistance bridge circuit) to obtain the measurement system accuracy for this parameter specified in Regulatory . Guide 1.23.

s - Generally,--the subtraction of two temperature measurements is considerably less accurate than a direct measure of temperature difference. At other sites reviewed by the Nuclear Regulatory Commission, an accuracy of vertical temperature gradient

. - determinedLby the subtraction of two temperatures has often exceeded the specification in Regulatory Guide 1.23.

A. Provide an expanded discussion of the measurement of vertical temperature gradient and clarify the measurement technique.

B. If vertical temperature gradient is determined by i subtraction of two temperatures, (1) indicate whether the' sensors are matched at installation and replacement; (2) indicate the " drift" between sensors found at instrument calibration; (3) identify the average period considered for the determination of temperature difference; and (4) clarify the computational procedures for the determination of temperature difference (i.e., is temperature difference computed for each interrogation of the sensors or from an ensemble average of temperature measurements).

k }J

Response

At the present time, analog strip chart data is used for all meteorological summaries and dose calculations. For each hour, an eyeball average of a representative 15-min period (usually 7 1/2 min before to 7 1/2 min after the hour) is used for an hour. The data is digitized on a digitizing machine that is checked for correct calibration each hour. Each data point digitized has a specific code designating type of instrument, level, scale range, and number of in. of chart per scale range.

All bad data periods or comments written on the stip chart are f-w written in a site log and kept indefinitely. After the data is

(

digitized, 3 hr/ day are plotted and overlayed on the strip chart

.to verify accuracy. Each data point has an associated status code indicating the quality of the data (good, questionable, or bad). When all digitizing errors are corrected, the data is -

color-plotted and checked by a meteorologist for reasonableness and possible errors.

' Question E451.14 (Regulatory Guide 4.2, section 6.1.3, and Safety Review Plan 2.3.5) (FSAR 2.3.5)

The discussion of the calculation of long-term diffusion

(~)/-

\- ' estimates presented in section 2.3.5 of tho Final Safety Analysis Report requires additional clarification. For example, the statement is made in section 2.3.5.2.1 on page 2.3.5-1 that "the release is at ground level." However, the discussion in section 2.3.5.2.3 on page 2.3.5-3 ~ states that "the plant vent

(~) release point is elevated." The atmospheric dispersion model k./ presented is for an elevated release.

A. For each release point identified in table 2.3.5-3, compare the release characteristics with the criteria in Regulatory Guide 1.111 for the determination of release mode (e.g., ground level or a mixture of partially elevated and partially ground level). Also, clarify the heights of release presented in this table to heights above ground, provide the heights of adjacent or nearby structures which could entrain

. effluents released from these locations, and provide i the direction of these structures relative to the l release locations.

(-)s

(_

B. The natural draft cooling towers appear to be less than 2000 feet from the Unit 1 containment structure, and these structures could significantly influence low-level airflow in the vicinity of the main plant release points for a number of wind directions.

Furthermore, plant releases, when the wind is blowing toward the cooling towers, could be entrained into the wake of these structures. For these situations, releases which may have been considered as partially elevated could behave more like ground level releases.

Provide additional information on the influence of the natural draft cooling towers on routine-releases of

C. Operation of the nuclear service cocling water towers could also affect releases of radioactive material to the atmosphere. Provide additional information on the frequency of operation of these towers, and provide L [)_ additional information on the influence of these towers on routine releases of radioactive material to the atmosphere.

D. Provide the numerical value(s) used for the parameter "H" discussed on oaaes 2.3.5-4 and 2.3.5-5 and defined as the " height of'the tallest structure in the nuclear

QE451.14-1 Amend. 1 2/84

VEGP-OLSER-Q

Response

All release points other than those designated as " plant vent" listed in table 2.3.5-2 are assumed to discharge into the building wake, wh.ch would effectively result in a ground level llh release with initial dilution in the wake cavity. The plant vents are located at the top-center of each reactor building dome and dischar9e at 419 ft msl as shown in table 2.3.5-3 of the FSAR. The vents discharge 19 ft above the top of their respective containments. The containment's highest points are 400 ft msl and they represent the highest structures onsite with llh the exception of the two cooling towers discussed below. Plant grade level is 220 ft msl.

A. Atmospheric dispersion calculations were made for two release conditions. For ground level releases, an initial dilution in the reactor building wake with a height H=180 ft was assumed, and for vent calculations a " wake split" (partially ground and partially elevated) model was used as described in FSAR section 2.-3T5.2.3. The use of a " wake split" model is justified sinc 1 the vent is higher than all adjacent structures. L'ooling towers are located at a distance sufficient to preclude significant interference with the vent plumes as discussed below.

B. Natural draft cooling towers are located generally east of the plant. Therefore, in an east wind, the center of the south cooling tower lies 518 m upwind of the center of the Unit 1 containment. The air flow disturbance created by the tower is a cavity attached to the lee surface of the tower, enclosed in an enveloping wake. The tower has the following dimensions: base diameter, 136.5 m; throat diameter, 76.2 m; top diameter, 84.1 m; and height, 164 m above plant grade which is 219.5 ft ms1. For this analysis, the tower will be considered as a vertical cylinder with d = 97.5 H = 164.0 m where d = diameter.

H = height.

and yielding lh d/Hc = 0.59 ,

QE451.14-2 Amend. 1 2/84

/~T VEGP-OLSER-Q Q

-The length of a cavity created by a vertical cylinder on.a ground plane is reported by Hosker in NOAA Oak Ridge ATDL Control No. 79/10 as 2.7d when d/Hc = 1.0 and 3.1d when d/Hc = 0.67

/_3 k/ Using the latter figure, the length of the cooling tower cavity is 3.1 x 97.5 = 302 m which corresponds to a normalized distance x/H c = 1.8 Flow conditions at the end of the cavity exhibit low wind speed and high directional variability. However, these conditions ameliorate with distance downwind. At

~

Unit 1, whose normalized distance from the tower is x/H c = 518/164 = 3.2,

! the mean velocity deficit is about 17 percent, according to Hosker figure 7.2Cb. No data is available on the turbulence intensity excess nor the streamline inclination in the vicinity of the Unit 1 release, but these should be small in comparison with flow irregularities created by the plant itself. The net effect of the concentration increase due to reduced mean velocity and concentration decrease due to increased turbulence should be small.

(g#

! ) In a west wind, some portion of the Unit 1 plume will

! impinge on the south cooling tower and mix in the

' cooling ' tower cavity and wake. The tower occupies about one-half of a 22 1/2 wind direction sector at this location. The horizontal concentration distribution is uniform by virtue of sector averaging.

Assuming that vertical mixing creates a uniform

QE451.14-3 Amend. 1 2/84 i

VEGP-OLSER-Q lh With X = 518 m and H c = 164 m, equation 1 reduces to X/Q = 3. 0 x 10 -5 f/u (la) where O f = the fraction of the vertical distribution, v = the wind speed at release height.

The definition of f is: O P

f=/ (2x) "/2exp (-0.5p 2)dp, (2)

where p = (H c - H p)/o r (3) and H c = cooling tower height.

Hp = plume centerline height.

When He, H p and a, are given, p is found by equation 3 and f is found by figure A-3 in Turner's Workbook.

The following table shows the calculation of f for several stabilities, assuming Hp = 80 m, Hc = 164 m, and X = 518 m.

The above analysis is applicable in the cavity where mixed concentrations are fairly uniform. Downwind of the cavity, the Gaussian distribution will reform in the vertical as wake turbulence decays and atmospheric turbulence is reestablished.

Calculations were made for four combinations of weather conditions assuming first that there were no towers and then that towers were in place. Results are summarized in table 451.14-1.

VEGP-OLSER-Q Values were within a factor of two with one exception. .

For the completely elevated case 1, the plume has not reached ground level, thus the concentration without jy

'the tover is 0. However, inspection of the joint

,\s frequency' tables showed the frequency of low wind speed (less than 4 mph at 150 ft) stable cases was less than

~0.3 percent toward either of the towers. Thus, the towers shoula not result in significant changes in

! _. routine ground level concentrations.

C. The nuclear service cooling water towers discharge vertically within 100 ft of the plant vents.

f

Therefore, plumes passing nearby or over the tower may be partially entrained in the cooling tower discharge

.- and lifted to a higher elevation. This would result in dispersion greater than estimated in the calculations for either ground or vent releases. The service water cooling tower height is about 44 ft above' grade and will not cause wake effects on elevated vent plumes.

VEGP-OLSER-Q Question E451.15 (Regulatory Guide 4.2, section 6.1.3, and Safety Review Plan 2.3.5) (FSAR 2.3.5)

/~) .The discussion of the rationale for not adjusting the

,'LJ straight-line atmospheric dispersion model to consider spatial and temporal variations in airflow out to a distance of 50 miles from the plant (page 2.3.5-1 of the Final Safety Analysis Report (FSAR)) requires further elaboration, particularly when other sources of information such as the National Weather Service

/'T . office at Augusta, Georgia and the Savannah River Laboratory are

> 'J available. Provide an assessment of airflow trajectories in the region of the VEGP considering additional concurrent (real-time), meteorological information available in the region to determine the appropriateness of the assumption of

- straight-line transport.

Resoonse Atmospheric dispersion calculations are made for routine releases to assure that peak offsite doses and concentrations of radioactive materials do not exceed Federal Regulations (10CFR r~ Part 20), established design guidelines (10CFR Part 50, Appendix

~(_]j I) and radiological technical specifications. Annual average dispersica calculations made for VEGP show that peak doses and concentrations will occur within the site boundary. This is consistent with releases that are partially at ground level.

Thus, even though a " wake split" model is used most releases have a ground level component due to the prevalent higher winds causing'some of the plume to be frequently trapped in the building wake. Thus, peak offsite doses are expected to occur at the site boundary. For recirculation to have an affect on the peak dose at this location, it would have to occur locally prior to significant dilution. Calculations for VEGP (FSAR table 2.3.5-8) show that on the average a factor of 10 dispersion occurs within the first 10 mi from the site

-[D boundary. Thus, generally speaking, to have a 10 percent effect on the peak concentrations, plumes would have to travel 5 miles downwind, turn around and pass directly over the plant. This is uncommon for the reasons discussed below.

,s A 1-year period of VEGP site hourly meteorological data was evaluated using a hodograph plotting computer routine. A 4 ')

separate hodograph was produced for each 24-hour period starting at 0100'each day. The resulting graphs were inspected visually for trends that could be indicative of recirculation. Few days were observed to exhibit the characreristic oval shape hodographs observed for river valleys or other locations where

()- recirculation is a concern.

QE451.15-1 Amend. 1 2/84

VEGP-OLSER-Q g A'out J 25 days were selected for further evaluation based on hodograph characteristics. A centerline trajectory analysis was made for each hour in each day to determine if plumes could be expected to pass over the site within the first 24 h after release. Such recirculations were found to occur on less than g

10 days and for less than 25 simulated releases (one each hour) out of a possible 8760 h in the year of data.

Therefore, it was concluded that recirculation would have very little effect on peak offsite doses due to routine releases.

Question E451.16 (Regulatory Guide 4.2, section 6.1.3, and Safety Review Plan 2.3.5) (FSAR 2.3.5)

N The high frequency of occurrence of extremely unstable

'(~)$_ -conditions (ses question E451.4) could increase the likelihood of fumigation if a large fraction of these conditions are immediately preceded by. moderately or extremely stable conditions. Fumigation could then occur a sufficient amount of

_~

time to be considered in estimating the annual average relative

/ . concentration (X/Q) and relative deposition (D/Q) values for

( releases assumed to be elevated. Provide an assessment of the occurrences of fumigation conditions at the Vogtle site and provide an estimate of the increase to annual average X/Q and D/Q values, if appropriate.

Response

Fumigation at VEGP during inversion breakup would not contribute significantly to annual average dispersion estimates. The time period in which fumigation would occur is short (on the order of less than 15 min). During the transition from a stable night '

7- condition to unstable daytime conditions, the following sequence

(g) . generally occurs. As the sun rises the stable ground is heated causing an unstable layer to be formed near the surface. As the l ground continues to be heated, the unstable layer grows steadily upward. While an elevated plume is above the unstable layer, it willinot penetrate downward. When the plume and the unstable layer meet, portions of the plume will fumigate down into the unstable layer causing a brief period of increased ground concentration. As the inversion level continues to rise the plume will be~ located within the unstable layer where it will be mixed normally. Since the time fumigation in occurring is quite short, the increase to annual average X/Q and D/Q will be insignificant.

Question E451.17 (Regulatory Guide 4.2, section 5.1.4)

(OLSER 5.1.4)

(~y The discussion of the atmospheric effects resulting from

-\ / operation of the natural draft cooling towers (section 5.1.4 of the OLSER) appears to be unchanged since submittal of the OLSER at the Construction Permit Stage. However, since that time, additional meteorological information has been collected at the site, and additional information on cooling tower modeling has

(~}

\~/

been developed (see NUREG/CR-1581, " Evaluation of Mathematical Models for Characterizing Plume Behavior from Cooling Towers,"

September 1980, and EPRI CS-1683, " Studies on Mathematical

-Models for Characterizing Plume and Draft Behavior from Cooling Towers," January 1981). Considering the additional onsite

. . meteorological information and the additional information on cooling tower modeling presented in the above references, reassess the estimates of visible plume location, extent, and

' frequency and salt deposition due to cooling tower drift. Also, confirm the rationale for the assumption of a uniform deposition of 305 lb/ acre / year for cooling tower drift within 1 mile of the plant, considering variations with meteorological conditions.

I Response Additional meteorological data collected at the VEGP site since

, submittal of the Construction Permit Stage Environmental Report

.(CPSER) is comparable to the data-which was used to predict plume behavior.

A review of : plume behavior at other power plants indicates that the meteorology, cooling tower operating characteristics, and plume behavior at VEGP'is comparable to those at the other

-plants. Several of these plants used the recent state-of-the-art. plume behavior and drift deposition models recommended by the Nuclear Regulatory Commission (NRC). Since i /_ . the predicted plume behavior at VEGP is in reasonable agreement

~ k-} - with that of.other plants, the plume predictions cited in the CPSER are-considered reasonable and more sophisticated modeling t

programs for characterizing plume behavior are unnecessary.

y_s The; estimate of uniform salt deposition of 305 lb/ acre / year

.within a 1-mile radius of the plant was based on conservative

-('-) design parameters, e.g., a conservative salt emission rate of 1050 lb/ tower. A more realistic salt emission rate, based on expected operating conditions would be 207 lb/ day from each tower. A review of the peak deposition rates at other power plants which used NRC-approved models for their drift rate i analysis and which have similar meteorological conditions as

. (k VEGP, indicates that the peak deposition will occur within 0.2

, QE451.17-1 Amend. 1 2/84

VEGP-OLSER-Q to 0.6 miles of the cooling towers. It is estimated that the peak deposition rate at the VEGP, in the prevailing wind direction will occur onsite and will be less than 31 lb/ acre / year at 0.6 miles from the cooling towers.

Extensive data on salt drift deposition patterns available from Susquehanna were used as a basis for predicting offsite peak salt deposition rates at VEGP. Specifically, the salt deposition reduction ratio at Susquehanna is 2-to-1 between the peak (located at 0.6 miles from the cooling towers) and a distance of 1.2 miles (distance from VEGP cooling towers to location of offsite peak in the prevailing wind direction).

Applying a similar deposition reduction ratio at VEGP and considering wind rose frequencies, the predicted offsite peak salt deposition rate at VEGP is estimated to be less than 15 lb/ acre / year in the prevailing wind direction.

The maximum predicted offsite salt deposition rate is estimated to be less than 21 lb/ acre / year which occurs at about 0.6 miles due east of the cooling towers at the site boundary.
