BVPS-2 UFSAR Rev. 18 2.1-1 CHAPTER 2 THE SITE This chapter primarily describes the site characteristics for the Beaver Valley Power Station as they existed when the facility was licensed. As such, current site characteristics may not agree with these descriptions. The site characteristics described here include description; geography and demography;

nearby industrial, transportation and military facilities;

meteorology, hydrology, geology, seismology, and geotechnical engineering. This information was gathered to support or develop the original plant design bases. Chapter 2 also contains evaluations of these site characteristics demonstrating

how applicable siting criteria were met at the time of original

licensing of the facility. This information was accurate at the time the plant was originally licensed, but is considered historical and is not intended or expected to be updated for the

life of the plant. Additionally, the operating term of the plant has been extended from 40 to 60 years by issuance of a renewed operating license. References to a 40-year plant life in this section are historical and have not been revised. Descriptions of requirements specific to the period of extended operation are contained in Chapter 19 of the UFSAR.

In the past, minor changes to site characteristics have been incorporated into Chapter 2. While updates were not required, these changes have not been removed. Therefore, some parts of

this chapter reflect more recent information.

2.1 GEOGRAPHY

AND DEMOGRAPHY

2.1.1 Site Location and Description

2.1.1.1 Specification of Location

The Beaver Valley Power Station (BVPS) is located in Shippingport Borough, Beaver County, Pennsylvania, on the south bank of the Ohio River. The site is approximately 1 mile

southeast of Midland, Pennsylvania, 5 miles east of East Liverpool, Ohio, and approximately 25 miles northwest of Pittsburgh, Pennsylvania. The coordinates of the Beaver Valley Power Station - Unit 2 (BVPS-2) reactor containment are 40 degrees 37 minutes 23 seconds north and 80 degrees 25 minutes 57 seconds west; the Universal Transverse Mercator coordinates

are 548,010 meters east and 4,496,890 meters north. Figure 2.1-1 shows the general site location.

2.1.1.2 Site Area Map

The BVPS site contains approximately 453 acres including 26 acres of right-of-way. Immediately to the west of the BVPS-2 reactor location, and also onsite, are Beaver Valley Power

Station - Unit 1 (BVPS-1) and the former site of the Shippingport Atomic Power Station (SAPS). The SAPS was managed

by DLC for the Division of Naval Reactors, U.S. Department of

Energy (USDOE). The SAPS terminated operations October 1, 1982

BVPS-2 UFSAR Rev. 18 2.1-1a and was dismantled by the USDOE. The Pennsylvania Department of Transportation has a right-of-way across the eastern end of the

site on which a portion of Pennsylvania Route 168, including the

southerly approach to the Shippingport Bridge, is located.

Local site topography, site boundary, and exclusion area are

shown on Figure 2.1-2, and the general site plan is shown on

Figure 1.2-1.

2.1.1.3 Boundaries for Establishing Effluent Release Limits

The BVPS-2 exclusion area is defined by a 2,000-foot radius around the BVPS-1 containment building and extending in part to

the north shore of the Ohio River (Figure 2.1-2). The exclusion area provides the basis for the Offsite Dose Calculation Manual

limits on gaseous effluents and meets the requirements of 10 CFR 50.67. The BVPS-2 gaseous releases will occur at the containment building, at the BVPS-1 cooling tower, and at the auxiliary building and turbine building ventilation vents. The shortest distance to the site boundary from the BVPS-2 containment building is approximately 1,500 feet. The nearest occupied residence is located approximately 2,323 feet from the centerpoint of the BVPS-1 and BVPS-2 reactor containment

locations. Within the site boundary there is a residence located on a 1 acre parcel not owned by the licensee (Figure

2.1-2). The residence is located approximately 4,000 feet SSW

of the BVPS-2 containment.

BVPS-2 UFSAR Rev. 12 2.1-2 Boundaries for establishing effluent release limits are defined and controlled as required by 10 CFR 20 to ensure that individuals are protected from exposure to radiation and radioactive materials. The description of the restricted area boundary

required by this section should be understood to be that presently approved for use in the Radiological Control Manual established for BVPS. The Radiological Control Manual describes how access to any areas required under this section is controlled for radiation protection purposes, including monitoring of access to these areas.

2.1.2 Exclusion

Area Authority and Control

2.1.2.1 Authority A 2,000-foot radius around the BVPS-1 containment building and an

extension to the north shore of the Ohio River constitutes the BVPS-2 exclusion area (Figure 2.1-2) as defined by 10 CFR 100.3(a). The United States of America (USA), owner of Phillis Island which is located approximately 400 feet off the shoreline from BVPS, through the purchase agreement with Dravo Corporation, has agreed not to use or permit the use of the land for any structure, place, or area where the public at large can assemble. The agreement, binding on the USA or on any future purchaser or lessee has an expiration date of 2010 and delineates and restricts

the uses which can be made of the island.

The Freeport Development Corporation purchased approximately 46 acres from DLC in 1995. This Land, located along the southern site boundary, includes 7.4 acres which are within the 2000-foot exclusion area boundary. An agreement binding on Freeport

Development Corporation or on any future purchaser or lessee delineates and restricts the uses which can be made of the land.

The Applicant owns all other land within the exclusion area, including the mineral rights to it.

A Consolidated Rail Corporation (ConRail) right-of-way on the site is approximately 400 feet from the BVPS-2 containment at its closest point. The line is controlled by the licensee and its use is limited to servicing BVPS-1 and BVPS-2. The Pennsylvania Department of Transportation has a right-of-way across the eastern end of the property on which a portion of Pennsylvania Route 168, the southerly approach to the Shippingport Bridge, is located.

Route 168 from the south follows along the northeast and east corner of the site and, crossing the Shippingport Bridge, joins

State Highway 68.

2.1.2.2 Control of Activities Unrelated to Plant Operation

As required by 10 CFR 100.3(a) and as discussed in the BVPS Emergency Preparedness Plan referenced in Section 13.3, the Applicant has control of removal of personnel and property from the exclusion area.

BVPS-2 UFSAR Rev. 15 2.1-3 The BVPS area is served by pipelines carrying natural gas and petroleum products. Six pipelines cross the BVPS-2 site: one natural gas pipeline and five petroleum product pipelines.

The Applicant has demonstrated control of the pipelines within the exclusion area, as evidenced by a DLC letter to the U.S. Nuclear Regulatory Commission (USNRC) (DLC 1978) and by relocation of the Mobil pipeline so that, in the unlikely event of a pipe rupture, pipeline contents would be diverted away from BVPS-2.

A coal ash slurry line from the Bruce Mansfield Plant (BMP) traverses the site. This line, owned in part by the Applicant, was originally routed to ensure that a failure of this line would

not affect BVPS-2.

2.1.2.3 Arrangements for Traffic Control

The only highway within the exclusion area, with the exception of the site access road, is State Highway 168 including the Shippingport Bridge. Beaver County Civil Defense and the Pennsylvania State Police have arranged to reroute the traffic on Route 168 in the event of an emergency, thus permitting crossing

of the Ohio River without using the Shippingport Bridge, as well as using roadblocks at other locations. Also, arrangements have been made with the Army Corps of Engineers and the Coast Guard for

navigation control on the Ohio River within the exclusion area in the event of an accident (BVPS-2 Emergency Preparedness Plan referenced in Section 13.3).

2.1.2.4 Abandonment or Relocation of Roads

Public roads traversing the exclusion area will not have to be abandoned or relocated to ensure the Applicant's control of the exclusion area.

2.1.3 Population

Distribution

Beaver Valley Power Station - Unit 2 (BVPS-2) is located on the Ohio River in the Borough of Shippingport in Beaver County, Pennsylvania. The county population in 1970 equalled 208,418, which was dispersed at a density of 478 people per square mile. According to the U.S. Department of Commerce (USDOC 1982a), between 1970 and 1980 the Beaver County population declined

approximately 1.9 percent to 204,441 at an average density of 469 people per square mile. Table 2.1-1 presents 1970 and 1980 populations and growth factors for townships, boroughs, and

districts within 10 miles of the site. Figure 2.1-3 identifies the location of BVPS-2 as well a s cities and tow nships within a radius of 10 miles surrounding the station.

BVPS-2 UFSAR Rev. 13 2.1-4 Population information contained in BVPS-2 PSAR Section 2.1.2 has been revised herein to reflect 1980 demographic data and trends.

Beaver Valley Power Station-Unit 2 PSAR Section 2.1.2 identifies the city of East Liverpool, Ohio as the nearest population center to the station. Due to declining population growth rates for the city of East Liverpool, its current and projected population does not approach 25,000 in the years 1980-2030, and therefore does not meet the criteria of 10 CFR 100 for the nearest population center.

The nearest population center, based on 10 CFR 100 criteria, is the township of McCandless, Pennsylvania, which supported a 1980

population of 26,250 and is located approximately 17 miles east of the station.

2.1.3.1 Population within 10 Miles The 1980 population within 10 miles of BVPS-2 was approximately 141,286, a 1.7 percent decrease from the 1970 total of 143,736. This population is projected to increase to approximately 155,232 by the year 2030. The l0-mile area contains portions of Beaver County, Pennsylvania; Columbiana County, Ohio; and Hancock County, West Virginia. Of the 16 boroughs, 17 townships, 2 districts, and 1 city located totally or in part within the 10-mile radius surrounding the station, the Borough of Aliquippa, Pennsylvania supported the largest population, 17,094 in 1980.

Population distribution within 10 miles of the station is based on a house count from U.S. Geological Survey (USGS) maps on which houses have been identified. Houses were used to estimate the area population by applying 1980 town-specific, people-per-household factors derived from U.S. Bureau of the Census data to sector house counts. House counts were supplemented and verified through field reconnaissance conducted during March and June, 1983. In urbanized areas, where no houses appear on the USGS maps, population was determined by land area allocation. It was

assumed that in urbanized areas, population was evenly distributed over the land area. Future population estimates within 10 miles of the station were adjusted by multiplying the 1980 base year population by the county-specific growth factors, supplied by the Pennsylvania Southwest Regional Planning Commission (1983), the Pennsylvania Department of Environmental Resources (1981), the West Virginia Department of Health (1981), and the Ohio Department of Development (1982). Finally, population densities were calculated by dividing the population in each annular sector by the sector's land area. Population and population densities in 1980 for townships, boroughs, and districts located within 10 miles of the station are presented in Table 2.1-2. Population

distribution for the 10-mile area for the years 1980 through 2030 is listed in Tables 2.1-3, 2.1-4, 2.1-5, 2.1-6, 2.1-7, 2.1-8 and 2.1-9. Figure 2.1-4 presents the location of annular sectors within the 0-10 mile area surrounding BVPS-2.

Population projections for the year 1985 are being used to approximate the population for the year of initial commercial operation of BVPS-2. The populations of 1985 and 1986, the year of actual commercial start-up, should not differ to any

significant extent. Therefore, since projections are calculated at 5-year intervals based on the decennial census, 1985 provides

BVPS-2 UFSAR Rev. 13 2.1-5 the best estimate of population distribution at the start of commercial operation.

2.1.3.2 Population betweeen 10 and 50 Miles

The area within 50 miles of BVPS-2, containing a total population of approximately 3,555,283 in 1980, is expected to grow to approximately 3,726,327 in the year 2000 and to reach a total of approximately 4,631,398 by the year 2030 (USDOC 1982a, 1982b, 1982c). Figure 2.1-5 presents the counties and major towns within the 50-mile radius of the station. Polar-grid sector populations between 10 and 50 miles are based on 1980 U.S. Census data for Pennsylvania and Ohio; 1980 US Census data, updated to reflect the 1982 redistricting of Hancock County, for West Virginia (Brooke-Hancock-Jefferson, W. Va. Metropolitan Planning Commission 1983a, 1983b); and population projections of the states of Pennsylvania, Ohio, and West Virginia. Sector populations were determined by assuming that the population of a minor civil division is evenly distributed over its geographic area. The proportion of each civil division area in each annular sector was calculated and applied to each civil division's total population, yielding the population in each annular sector. Population growth factors, based on 1981 projections, supplied by the Pennsylvania Department of Environmental Resources (1981); 1983 updated projections for Beaver County, supplied by Pennsylvania Southwest Regional Planning Commission; 1981 projections, supplied by the West Virginia State Department of Health; and 1981 projections updated in 1983, supplied by the Ohio Department of Economic and Community Development, were applied to each civil division assuming that each portion would maintain its relative share of any population change (Pennsylvania Department of Environmental Resources 1981; Pennsylvania Southwest Regional Planning Commission 1983; Ohio Department of Economic and Community Development 1981 and 1983; and West Virginia Department of Health 1981). Population density

was calculated by dividing the population in each sector by its land area. Figure 2.1-6 presents the annular sectors for population distribution within 10-50 miles of BVPS-2. Populatio n distribution the 50-mile area for the years 1980-2030 is listed in Tables 2.1-10 , 2.1-11 , 2.1-12 , 2.1-13 , 2.1-14 , 2.1-15 and 2.1-16. The 50-mile region is heavily populated. In 1980, 22 boroughs, townships, and cities exceeded a population of 25,000 people.

However, only three cities of over 100,000 people are located in the region: Pittsburgh, Pennsylvania; Canton City, Ohio; and Youngstown City, Ohio (USDOC 1982a, 1982b, and 1982c). Table 2.1-24 lists civil divisions with more than 25,000 people. Table 2.1-25 lists an additional six civil divisions projected to contain 25,000 or more people in the period 1980-2030.

Supporting a combined 1980 population of approximately 4.2 million, seven standard metropolitan statistical areas (SMSAs) are located totally or partially within the 50-mile radius of the station. Table 2.1-26 lists the seven SMSAs and their 1970 and 1980 populations and growth factors. Figure 2.1-9 represents the SMSAs within the 50-mile region.

BVPS-2 UFSAR Rev. 13 2.1-6 2.1.3.3 Population between 50 and 350 Miles Figure 2.1-7 shows the 350-mile region surrounding BVPS-2.

Population distribution within 350 miles of the station for the years 1980-2030 was calculated in the same manner as that for 10-50 miles and is listed in Tables 2.1-17, 2.1-18, 2.1-19, 2.1-20, 2.1-21, 2.1-22 and 2.1-23. Figure 2.1-8 locates the annular sectors for population distribution within 50-350 miles of the

station.

Population sector distributions and projections for the 50-350 mile area surrounding BVPS-2 are based on 1980 US Census data, population projections for the District of Columbia and the 13 states located in the 350-mile area, 1981 Canadian census data, and population projections for the Canadian Province of Ontario.

(Delaware Development Office 1982, Illinois Office of State Planning 1981, Indiana University 1981, Maryland Center for Health Statistics 1980 and 1981, Maryland Department of State Planning 1981, Metropolitan Washington Council of Governments 1979, Michigan Department of Management and Budget 1978, New Jersey Department of Labor 1982, New York State Economic Development Board 1978, North Carolina Office of State Budget and Management 1981, Ohio Department of Development 1982, Ohio Department of Economic and Community Development 1983, Ontario Ministry of Treasury and Economics 1979, Pennsylvania Department of Environmental Resources 1981, Pennsylvania Southwest Regional Planning Commission 1983, Statistics Canada 1981, Tennessee Valley Authority 1980, University of Louisville 1981, Virginia Department of Planning and Budget 1980, West Virginia Department of Health 1981).

2.1.3.4 Transient Population

Within 10 miles of BVPS-2 several land uses attract seasonal and daily transient populations. Table 2.1-27 presents approximate daily transient population by annular sector within 10 miles of

the station. Land uses and facilities that account for transient population include industries, recreational sites, and educational institutions. Transient population variations associated with

industrial employment and school enrollment represent redistribution of existing population within the 10-mile area.

2.1.3.4.1 Industry Industries and employment are discussed in Section 2.2.2.

2.1.3.4.2 Educational Institutions

Schools within the 10-mile radius area generate daily variations in population distribution. Table 2.1-28 identifies educational institutions within 10 miles of the station and their enrollments.

BVPS-2 UFSAR Rev. 0 2.1-7 Total school enrollment for the 10-mile area equals approximately 29,000 (Pennsylvania Department of Education 1982; Western Beaver School District 1982; Beaver Area School District 1982; Blackhawk Area School District 1982; Hopewell Area School District 1982; Southside Area School District 1982; Center Area School District 1982; Midland Public Schools 1982; West Virginia Department of Education 1982). However, approximately 77 percent of the total, or 22,639 students served by the elementary and secondary schools reside within the 10-mile area (Pennsylvania Department of Education 1982; Western Beaver School District 1982; Beaver Area School District 1982; Blackhawk Area School District 1982; Hopewell Area School District 1982; Southside Area School District 1982; Center Area School District 1982; Midland Public Schools

1982; West Virginia Department of Education 1982).

Three colleges are located within the l0-mile area: the Beaver

Campus of Pennsylvania State University, Beaver Community College, and the East Liverpool Campus of Kent State University. Pennsylvania State University-Beaver Campus is located in Monaca, approximately 8.5 miles east-northeast of the station. The university serves 200 on-campus residents, 1,004 full-time day students, and an additional 700 part-time evening students, generally residents of Beaver County (Pennsylvania State University 1982).

Beaver Community College is also located east-northeast of BVPS-2 at a distance of 7.5 miles. There are no on-campus residents at the college. Its fall and spring enrollment in 1981 equaled 964 snd 1,109 full-time day students and 1,110 and 1,174 part-time evening students, respectively. The college operates a summer school which served 1,356 full and part-time students in 1981 (Beaver Community College 1982). Finally, the East Liverpool Campus of Kent State University is located approximately 7.5 miles west of BVPS-2. The East Liverpool Campus serves a 1982-83

enrollment of 660 full time students. No on-campus residents are associated with this campus (East Liverpool Campus of Kent State University 1983).

2.1.3.4.3 Parks and Recreation

Local recreational sites generate a moderate level of transient population. Total estimated daily transient population associated with recreation equals 3,904 people; total 1981 visitor-day attendance figures of the recreational areas within 10 miles of the station equals 1,424,962. Table 2.1-29 presents transient population counts for recreational areas by annular sector. The Pennsylvania section of the 10-mile area contains the Raccoon State Park, the Brady Run County Park, and State Game Lands Numbers 173 and 189. No visitor attendance figures exist for the state game lands (Pennsylvania Department of Natural Resources 1982a). However, combined state and county park attendance within the Pennsylvania section totaled 501,152 in 1981. Both of these

parks are located between 6 and 9 miles from the station. Camping facilities are available at both parks. Camping attendance in 1981 at the Raccoon BVPS-2 UFSAR Rev. 0 2.1-8 State Park equalled 14,423 visitor days (Pennsylvania Department of Natural Resources 1982a). No camping counts are recorded for the County park, which operates annually from May to September and attracts predominantly county residents (Pennsylvania Department

of Natural Resources 1982b, and Beaver County Parks Department 1982).

Two additional state parks are located within 10 miles of the station: Tomlinson State Park in West Virginia and Beaver Creek State Forest in Ohio. The 1981 attendance counts for West Virginia and Ohio state recreational areas totaled 923,810 persons. Beaver Creek State Forest accounted for approximately 79 percent of this total, or 729,930 visitors. Of its 1981 total, the state forest includes 34,110 campers (Ohio Department of Natural Resources 1982). Tomlinson State Park, located approximately 10 miles southwest and west-southwest of the station, attracted 193,880 visitors in 1981. In 1981, 50 campsites were opened at the park; however, no camping counts are available.

2.1.3.5 Low Population Zone

The low population zone (LPZ) surrounding BVPS-2 encompasses an area within approximately a 3.6-mile radius of the BVPS-2 reactor containment centerline. The distance for the LPZ is determined based on the requirements of 10 CFR 100. No population centers with populations equal to or greater than 25,000 exist within the LPZ, or within an area of radius 1 1/3 times the LPZ radius, approximately 4.8 miles.

The 3.6-mile boundary also meets the requirement that the LPZ

should be an area in which sufficient protective measures can be taken to assure that the resident population does not receive a dose in excess of a specified level resulting from a postulated

accident condition.

The LPZ contained a 1980 resident population of approximately

10,828 at an average density of 284 people per square mile. Table 2.1-30 presents the 1980 LPZ population distribution. By the years 1985 and 2030 the LPZ population is expected to have increased to 11,114 and 11,656 at average densities of 292 and 306 people per square mile, respectively. Table 2.1-30 identifies permanent population distribution in the LPZ. Transient population within the LPZ is identified by institution and by sector in Table 2.1-31 and 2.1-32, respectively.

2.1.3.6 Population Centers The nearest population center to BVPS-2, as defined by 10 CFR 100, is the township of McCandless, Pennsylvania which supported approximately 26,250 people in 1980 with a density of 1,608 people per square mile. The township's closest corporate boundary to the station is approximately 17 miles east. Table 2.1-24 lists existing population centers with over 25,000 people. Cities and towns BVPS-2 UFSAR Rev. 13 2.1-9 projected to become population centers in the period 1980 to 2030 are listed in Table 2.1-25.

2.1.3.7 Population Density

The area within 30 miles of the station is expected to c ontain approximately 1,570,449 people at an average density of 565 people per square mile in 1985. This density is only slightly greater than the USNRC comparison figure of 500 people per square mile given in Regulatory Guide 1.70, Revision 3. Population within the

area is expected to increase to a total of approximately 2,150,291 by the year 2030. Population density in 2030 will reach an average of approximately 773 people per square mile, which is below the USNRC density comparison for the end year of plant life of 1,000 people per square mile. Tables 2.1-33, 2.1-34 and 2.1-35 present population density by sector for distances 0-10 miles for the years 1980, 1985, and 2030. Sector population density for distances 10-50 miles for the same years are presented in Tables 2.1-36 , 2.1-37 and 2.1-38. 2.1.4 References for Section 2.1

2.2.1 Location

and Routes

The area in which the Beaver Valley Power Station (BVPS) is located is part of the large industrial complex centered around the city of Pittsburgh. Due to the combination of available raw materials, product markets, and transportation facilities, the region has developed into a major industrial center, with iron and steel manufacturing constituting the most important factor in the region's economy. The steep slopes and general topography of the Ohio River valley have contributed to the development of river mill towns where the majority of industries

and residences are located on flat shelves of land adjacent to the river.

The region is served by five transportation systems: waterways, railroads, highways, airways, and pipelines.

The rivers provided the first major regional transportation system. The Ohio River, under the control of the U.S. Army Corps of Engineers, still serves as a major route for the transport of industrial materials. The normal river tow, generally 1,200 feet in length (including towboat), follows the channel which is located about 0.3 mile from BVPS. Section

2.2.3 describes

the Beaver Valley Power Station - Unit 2 (BVPS-

2) intake structure location and the potential for river transport accidents affecting the intake or general BVPS-2

structures.

The railroads transport the bulk of industrial materials. The placement of the rail lines was governed by the topography. Because the railroads needed level and continuous corridors, they followed essentially the same courses as the rivers and

streams. One of the first rail lines in the region ran from Pittsburgh up the eastern bank of the Beaver River to the Great Lakes region. That line is now one of the main lines of the

Consolidated Rail Corporation (ConRail). Another heavily traveled ConRail line follows the north bank of the Ohio across the river from the station site. A 30-foot-wide easement, maintained by ConRail, traverses the BVPS site. This line is of minor importance since the line is controlled by the licensee and its use is limited to the servicing of BVPS-1 and BVPS-2.

Pennsylvania State Highway 68 provides the main access from the residential areas east of the site to the industrial complexes along the north bank of the Ohio River. State Highway 168 from the south follows roughly along the northeast and east corner of the site and joins Highway 68 immediately across the river from

the site. State Highway 18 provides additional access to the east of the site while U.S. Route 30 passes by 3 miles southwest of the site. Transportation routes within 5 miles of the

station are shown on Figure 2.2-1.

The interstate highway nearest the site is the Pennsylvania Turnpike (I-76), which runs through the northeastern section of Beaver County about 15 miles northeast of the site. Interstate 79, which runs north and south, is located about 18 miles east

of the site.

BVPS-2 UFSAR Rev. 0 2.2-2 The outmoded highway system has hampered recent development of the local area and of the region as a whole. The topography of the area and the location of the communities dictated that early roads would be located in the river valleys. The Beaver Valley Expressway (Route 60) provides the first four-lane, limited-access highway between the industrial centers of Beaver County and Pittsburgh. The expressway traverses north to south about 6 miles east of the site. This expressway will have a significant influence on the future growth and development of the region. There are no plans at present for other major highways within 10

miles of the site.

2.2.2 Description

of Facilities, Products, and Materials

About 40 percent of the Beaver County labor force is employed by manufacturing companies. Approximately 67 percent of the total manufacturing labor force is employed in the primary metals group - blast furnaces, steelworks, and rolling mills. Heavy manufacturing employs approximately 29 percent of the manufacturing labor force, concentrated in fabricated structural steel. The remainder of the manufacturing labor force is employed in the electrical equipment industry, the stone, clay, glass, and concrete industries, and the chemical group. Employment in Beaver County is identified by industry category in Table 2.2-1 (Southwestern Pennsylvania Regional Planning

Commission 1983).

Pennsylvania Power Company's Bruce Mansfield Plant (BMP),

located approximately 1 mile northeast of the site, employs about 1,000 persons. The nearest industrial activity to the site is the steel mill complex in Midland, between 1 and 2 miles northwest of the site, where approximately 250 persons are employed.

The urban complex of East Liverpool, Ohio, including Chester and Newell, West Virginia, begins about 5 miles west of the site and stretches for several miles down the Ohio River. The East Liverpool area's industrial base depends on pottery for most of its employment, even though the pottery industry has declined due to foreign competition and the use of plastic materials for

tableware.

Table 2.2-2 lists major employers in the 10-mile area surrounding the site. Figure 2.2-2 shows their general locations.

Mineral resources including coal, clay, gas, oil, sand, and gravel are found in the region surrounding the site. Bituminous

coal is the most important mineral being extracted and coal reserves are considered extensive.

Relatively few workers are presently engaged in mining operations; however, the Southwestern Pennsylvania Regional Planning Commission (SPRPC)

forecasts an increase in mining

BVPS-2 UFSAR Rev. 0 2.2-3 employment (SPRPC 1978). In Beaver County, deep mining is the predominant method used to extract coal, although extensive areas of strip mining are found within the region, especially in northern Beaver County and in northern Washington County. One industrial operation, the Pegg's Run Coal Company, is located in Shippingport Borough approximately 1 mile southwest of the site.

Employing about 60 people, the company operates coal washing

facilities and a deep mine.

The majority of storage tank facilities for gasoline and oil in the site vicinity are located along the river. The closest oil tanks are in Midland, Pennsylvania, directly across the river from the site (SWEC 1980a). Storage tank facilities in the site

vicinity, identified on Figure 2.2-3 , are equipped to handle shipments by barge. Across the r iver from the site, at river mile 34.8, a Pennzoil barge facility handles an average of two outbound shipments per week and one inbound shipment per month of gasoline and fuel products. At river mile 35.2, Mobil Oil Corporation maintains barge facilities to serve the Midland Terminal used by Mobil Pipe Line Company. Mobil's barge facility is presently inactive.

At river mile 33.3, Shell Chemical Corporation ships approximately ninety percent of its chemicals by barge to the Great Lakes Terminal and Transport Facility at Industry, PA.

These inbound shipments occur approximately once a month. No outbound shipments are made by barge. Connecting pipelines link the barge facilities to the tank storage areas. Storage tank

facilities and contents are described in Section 2.2.3.

The area is served by pipelines carrying natural gas and petroleum products (SWEC 1980b). Pipelines and their products are described in Table 2.2-3 and shown on Figure 2.2-3.

There are eight airports within a 15-mile radius of BVPS. Four airports are located in Pennsylvania: Greater Pittsburgh International, Beaver County, Fino, and Kindelberger; Columbiana, Dyer, and Johnston airports are in Ohio; and Herron Airport is in West Virginia. According to criteria set forth in USNRC Regulatory Guide 1.70, Revision 3, the operations of Greater Pittsburgh, Beaver County, Fino, and Herron airports must be examined in detail due to their proximity to the power plant and/or due to their respective levels of operation.

Appendix 3.B describes these four airports, and accidents which have occurred in their vicinity, as well as the analyses performed to define the probability of an aircraft striking

BVPS-2. The total number of persons employed in southwestern Pennsylvania is expected to increase approximately 15 percent between 1974 and the year 2000 (SPRPC 1978). However, not all industry groups will experience this growth. Historically, the

southwestern Pennsylvania region has been a center for heavy industry dominated by iron and steel manufacturing. The employment forecast for the region (Table 2.2-4) indicates that

in the manufacturing category, BVPS-2 UFSAR Rev. 0 2.2-4 employment gains in machinery and chemical manufacturing will be offset by declines in primary and fabricated metals production and in the stone industries. The net result will be a slight decrease in the number of persons employed in manufacturing production jobs. Employment statistics for the southwestern Pennsylvania region show that this has been the trend for the past several years (Pennsylvania Office of State Planning and Development

1976). Increased automation, foreign competition, dispersion of markets, and the development of steel-making capacity in other areas of the country have all contributed to this trend.

Nonmanufacturing job employment is projected to grow about 12 percent between 1974 and the year 2000 (SPRPC 1978). The largest

growth will occur in mining and trade (Table 2.2-4).

2.2.3 Evaluation

of Potential Accidents

2.2.3.1 Determination of Design Basis Events

A commodity traffic analysis of the transportation routes near the BVPS-2 site was carried out to identify materials potentially capable of causing explosions and subsequently forming vapor

clouds in the event of an accidental spill. This analysis included a comprehensive review of the Ohio River barge traffic data compiled by the U.S. Army Corps of Engineers, telephone and letter surveys of the nearby industrial facilities, and the ConRail-Midland Node Activity Report (ConRail 1980).

The Ohio River barge traffic data indicate that the bulk of the activity involves gasoline transport. The shipment of flammable compressed gases is insignificant. The potential risk to BVPS-2 due to barge traffic on the Ohio River has been addressed and subsequently resolved in the BVPS-2 PSAR Amendment 12 dated December 21, 1973 and Amendment 13 dated February 28, 1974. As

documented in the BVPS-2 PSAR, the risk was eliminated by the construction of an alternate cooling water intake structure. The alternate intake structure is capable of providing heat sink functions in the event of the loss of the primary intake structure as a result of a gasoline barge impact and explosion (Section 9.2.1.2).

Telephone and letter surveys of the nearby industrial facilities show that there are no known shipments of flammable compressed gases which use the Shippingport Bridge on Route 168 (SWEC 1980a).

There are regular bulk shipments of solvents and gasoline by tank trucks which use the bridge. However, these shipments are not

considered to cause an explosion or vapor cloud hazard in the event of an accidental spill.

Pipelines carrying natural gas and other petroleum products in the vicinity of BVPS-2 are identified in Table 2.2-3. None of the pipelines carry liquified hydrocarbon gases, such as LNG or LPG, which can form combustible vapor clouds. The only source of potentially combustible vapor cloud is a rupture of the pipeline owned and operated by Mobil Pipeline Company. This pipeline is

used for transporting gasoline, kerosene, and heating oil. A 2,150-foot section of this pipeline skirts the BVPS-2 site, with the closest distance to a safety-related structure (the BVPS-2 diesel generator building) being approximately 950 feet. Because of the close proximity of BVPS-2 UFSAR Rev. 15 2.2-4a the pipeline to BVPS-2, the probability of an explosion/fire due to a pipeline rupture is discussed in Section 2.2.3.1.1.

The transportation of flammable liquified gases by ConRail is a concern due to the potential for explosions and the formation of vapor clouds in the event of an accident. The probability of a vapor cloud explosion resulting from a railroad transportation

accident is discussed in Section 2.2.3.1.2.

2.2.3.1.1 Mobil Pipeline Rupture

A pipeline owned and operated at time of BVPS-2 license by the Mobil Pipe Line Company used for transporting gasoline, kerosene, and fuel oil skirts the BVPS-2 site. The closest distance between this pipeline and a safety-related structure (the diesel generator building) is approximately 950 feet. The probability of an explosion/fire resulting from rupture of the pipeline has been calculated, using the following model:

PPPEFPRIGN where: P EF = Probability of explosion/fire

P PR = Probability of pipeline rupture

PIGN = Probability of ignition The calculation of P follows:

Probability of Pipeline Rupture, P The pipeline section that skirts BVPS-2 is approximately 2,150 feet in length. This section of pipeline is estimated to consist of approximately 54 sections, each measuring 40 feet long. A failure rate of 3x10 event per hour per section for pipes greater than 3-inches in diameter (USNRC 1975) was used to calculate the rupture probability. It was assumed that the pipeline would operate 25 percent of the time (Mobil Pipe Line Co. 1984).

The probability of rupture in the pipeline skirting BVPS-2 (P) was therefore calculated to be 3.55x10 rupture per year.

Probability of Ignition, P The pipeline is used to transport gasoline, kerosene, and fuel oil.

The probability of ignition is conservatively based on rupture of the pipeline when transporting gasoline, since it is more flammable than either kerosene or fuel oil. Using the gasoline release data supplied by the Mobil Pipe Line Company (1983) to analyze a gasoline spill, the maximum size of a gasoline-covered area was estimated. This area was then used to estimate the probability of gasoline

vapor ignition using the data in the Battelle (1980) report. The probability of ignition was estimated to be 6.15x10, assuming that a gasoline spill from the pipeline occurs.

BVPS-2 UFSAR Rev. 0 2.2-4b The Probability of Explosion/Fire, P The probability of explosion/fire resulting from rupture of the pipeline is, therefore:

PPxPRIPRIGN (.)(.)3551061510 72 xx 2210 8.x event per year This probability is lower than 1x10, therefore, this event is not considered a design basis accident.

BVPS-2 UFSAR Rev. 0 2.2-5 Explosions and Vapor Clouds The formation of a vapor cloud and its subsequent explosion due to the spill of a compressed liquified gas is a relatively rare occurrence. There are several mitigating

BVPS-2 UFSAR Rev. 0 2.2-6 effects which act to prevent the formation of vapor clouds. The spill has to be of a significantly large size to serve as a vapor cloud source. The dissipation of vapors released during minor leaks and ruptures is rapid and prevents the formation of an unconfined vapor cloud. Even when the spill size is large, an unconfined vapor cloud can exist only if it can overcome the dissipative effects of atmospheric turbulence and avoid encounters with an ignition source. Atmospheric turbulence promotes dispersion and the wind speed dilutes the vapors. An immediate encounter with an ignition source (almost always

present during an accident) results in consumption of vapors locally. Thus, most accidental spills of compressed liquified gases do not form vapor clouds.

Flammable compressed gases are shipped via the railroad line adjacent to BVPS-2. A listing of these gases is given in Table

2.2-6. In the event of a catastrophic rupture, the liquified gas is released to the atmosphere under pressure, and a fraction of the liquid is flashed. The remaining liquid, due to the cooling effect, will remain as chilled liquid and will vaporize further upon contact with the ground. The rapid loss of lading will result in the formation of an unconfined vapor cloud which

is at least partially mixed with air.

The probability of a vapor cloud explosion adjacent to BVPS-2 is

based on the product of the probability of a catastrophic rupture event, the probability of a flammable vapor cloud formation, the probability of wind speed, and the probability of

the vapor cloud encountering an ignition source.

The probability of a flammable vapor cloud explosion is thus:

Iiwvfiri i R vePfPPPxxx 1 (2.2-2) where: P = Probability per year of a vapor cloud explosion, R = Number of hazardous shipments likely to produce vapor clouds, PProbability of catastrophic rupture events per year for the i-th hazardous material, P = Probability of the i-th hazardous material forming a flammable vapor cloud, fProbability of wind speed which promotes transport and mixing with air, P = Probability of finding an ignition source given BVPS-2 UFSAR Rev. 0 2.2-6a that a flammable vapor cloud is formed by the i-th hazardous material.

BVPS-2 UFSAR Rev. 0 2.2-7 Number of Hazardous Materials, R The hazardous materials likely to produce an unconfined vapor cloud explosion due to a catastrophic rupture event on the

railroad line adjacent to the BVPS-2 site are given in Table 2.2-5. Probability of Catastrophic Rupture Events, P The probability of catastrophic rupture events per year

involving the i-th hazardous material is estimated using the model described in Section 3.5.1.5. These probabilities are given in Table 2.2-6. Probability of Forming a Flammable Vapor Cloud, P All catastrophic rupture events involving flammable compressed gases do not necessarily result in the formation of vapor clouds. The usual case is that ignition source is available in the immediate vicinity of an accident and a fire results. Depending on the actual accident scenario, the fire, at worst, would cause the tank car contents to be released and result in the formation of a "fireball." The "fireball" accident scenario has no incident pressures associated with it of concern to BVPS-2 structures. However, the formation of a flammable vapor cloud

and its subsequent ignition is a potential safety concern. The formation of a flammable vapor cloud also implies that an ignition source was not available in the immediate vicinity of

the accident.

Accidental spill data (USDOT 1981) was used to estimate the probability of forming a vapor cloud given a catastrophic rupture event. This probability was estimated to be 0.1 event per year as an upper limit.

Wind Speed Probability, f Flammable vapor-air mixtures are explosive within narrow concentration limits. A mixture too rich or too lean may burn but is not explosive. Favorable wind speed would allow optimum

transport and mixing of air with the vapor cloud. The probability of the favorable wind speed was conservatively assumed to be 1.0.

Probability of Encountering an Ignition Source, P In a catastrophic rupture event involving flammable compressed gases, an immediate encounter with an ignition source will typically result in a torching effect. In this case, the released gas is consumed immediately and the flames are confined locally. The torching effect can lead to an enlarged fire or, at worst, the formation of a

BVPS-2 UFSAR Rev. 0 2.2-8 "fireball." The probability of encountering an ignition source is nearly 1.0 in the immediate vicinity of the accident and decreases away from the accident site. The probability of ignition for the torching effect, fire, and "fireball" formation

is therefore assumed to be 1.0.

The formation of a flammable vapor cloud in and around the scene of the accident site implies that an immediate ignition source was not encountered. The cumulative probability of the vapor cloud encountering an ignition source increases with the area of the cloud. However, effects associated with dispersion of the vapor cloud reduce the local probability of ignition as the area of the vapor cloud increases.

The probability of ignition was estimated using Table 9-2 of the Battelle (1980) PNL-3308 Report. The use of this table requires

an estimation of the area of the vapor cloud for a conservatively estimated instantaneous release of the compressed liquid.

The area of the unconfined vapor cloud was estimated by calculating the weight (thereby vapor volume) of the liquid which vaporizes upon exit from a tank car, and the depth of the unconfined vapor cloud above the ground.

The weight fraction, which vaporizes upon exit from a tank car is given by:

][)(exp1TiTbCv f (2.2-3) where:

f = Fraction of the liquid that flash vaporizes, C = Liquid heat capacity (J/Kg K), T = Normal boiling point ( K),

T = Initial temperature of the stored liquid ( K), = Heat of vaporization (J/Kg).

The fraction vaporized, for all the hazardous materials, was under 0.4. To be on the conservative side, the fraction vaporized was taken to be 0.5. Thus, knowing the weight of tank car lading vaporized, the volume of the vapor cloud was estimated. The fraction of air in the vapor cloud was ignored

for this purpose.

BVPS-2 UFSAR Rev. 0 2.2-9 The height of the vapor cloud above ground level was estimated by the following relation given by Kaiser and Griffiths (1982):

L = ghpl P a u*2 (2.2-4)

where: L = 2 (for a heavy gas vapor cloud)

g = Gravitational acceleration (ft/sec) h = Height of the vapor cloud (ft) p = Density differences between cloud vapor and ambient air (lb/ft) a = Density of air (lb/ft) u* = The vapor cloud spreading velocity (ft/sec).

The spreading velocity was assumed to be equal to the wind velocity.

The estimated ignition probabilities are given in Table 2.2-7. The Probability of an Unconfined Vapor Cloud Explosion, P The probability of an unconfined vapor cloud explosion at the BVPS-2 site was calculated using the preceding model. These probabilities are listed in Table 2.2-8.

The probability of an unconfined vapor cloud explosion due to the rupture of a tank car involving flammable compressed gas is 2.65 x 10 per year. This probability is lower than 1.0 x 10 per year for such events as recommended by NUREG-0800 (USNRC 1981a) Section 2.2.3. Thus, the unconfined vapor cloud explosion hazard does not constitute a design basis event for

BVPS-2. 2.2.3.1.2 Toxic Chemicals

According to Regulatory Guide 1.78, both onsite and offsite potential toxic gas hazards must be considered. Any toxic substance stored onsite in a quantity greater than 100 pounds must be evaluated. Offsite sources include stationary facilities as well as transportation sources (truck, rail, and

barge) within five miles of the site.

BVPS-2 UFSAR Rev. 12 2.2-10 A complete evaluation of toxic gas hazards for the BVPS site has been performed by SWEC (1981a) and submitted to the USNRC for inclusion in the BVPS-1 docket (Docket No. 50-334). This Control Room Habitability Study, which is also applicable to BVPS-2, was accepted by the USNRC (1982). A summary of the study follows.

For the BVPS-2 site, potential sources of toxic chemical hazards include chemicals stored onsite, two stationary sources within five miles of the site, and three transportation sources. The nine toxic chemicals stored onsite, along with stored quantities and distances from the control room air intake, are presented in Table 2.2-9. The quantities shown in this table are based on the size of the largest single storage container. The two stationary sources include toxic chemicals stored at the nearby Pennsylvania Power Company's Bruce Mansfield Plant (BMP), located one mile (Table 2.2-10) from the BVPS-2 control room air intake, and at Arco Polymers Inc. in Monaca, Pennsylvania, at a distance of about 4.5 miles from the control room air intake. The chemical types and quantities stored at these locations are given in Table 2.2-10. The three transportation sources of hazardous materials include the ConRail line which runs along the north shore of the Ohio River, barge traffic on the Ohio River, and truck traffic to and from the two stationary sources. The rail line and barge traffic pass within 0.4 mile and 0.15 mile of the control room air intake, respectively.

Appendix A of the Control Room Habitability Study (SWEC 1981a) contains the hazardous materials node report for Midland, Pennsylvania, provided by ConRail, which lists the shipment frequency and quantity of all potentially toxic substances shipped by rail during the period of January 1978 through June 1979. Appendix B of the same study contains the domestic commodity movements at mile 35 of the Ohio River for the calendar years 1977 and 1978, along with the commodity classification codes. These periods are considered representative of the traffic to be expected

in this area.

The hazardous chemicals shipped by truck and at the stationary sources in the vicinity of the BVPS-2 site are determined from a comprehensive survey of industries in the area (SWEC 1980a). The responses to this survey indicate that only two truck routes pass within 5 miles of the site: along Route 18 (2 miles from the control room intake) for shipments to and from Arco Polymers Inc. in Monaca, Pa. and along Route 168 (0.23 mile from the control room air intake) for deliveries to BMP. The route for shipments to BMP was conservatively assumed to be the closest one to the BVPS-2 site since the actual route was not given in the survey response. The chemicals shipped by truck are the same as those indicated in Table 2.2-10, with the exception of benzene from Arco which is shipped only by barge.

Only those chemicals which have the potential to form a toxic vapor cloud or plume after release to the environment need to be evaluated. This criterion is met by all of the chemicals listed in Tables 2.2-9 and 2.2-10 with the exception of sodium hydroxide solution which does not form a toxic vapor cloud due to its very low vapor pressure. In addition, not all of the 341 hazardous materials listed in the ConRail node report (ConRail 1980) fall into this category. Many of these materials are not toxic to humans, many are solids which cannot emit a vapor, and still others are liquids with very low vapor pressures which evaporate at a negligible rate.

BVPS-2 UFSAR Rev. 0 2.2-11 As a result of these considerations, 119 of the 341 hazardous substances shipped by ConRail were evaluated for possible toxic effects on the control room operators. Similarly, only five of the commodities shipped by barge were determined to be toxic

substances.

The criteria for determining chemical toxicity and setting limits for habitability determinations are derived from regulatory guidance. According to Regulatory Guide 1.78, the toxicity limit of a chemical is the maximum concentration that

can be tolerated by an average human being for two minutes without physical incapacitation (severe coughing, eye burn, severe skin irritation). NUREG-0800 (USNRC 1981a), Standard Review Plan Section 6.4 states that acute effects should be reversible within a short period of time (several minutes) without benefit of medication other than the use of a self-

contained breathing apparatus. The acute toxicity limits listed in Regulatory Guide 1.78 are used in this study wherever possible. However, acute toxicity limits based on the criteria discussed previously were not available for most of the chemicals in this study. In these cases, acute toxicity limits were set subjectively using more recently available information from authoritative sources (Regulatory Guide 1.78; Patty 1978; SWEC 1981b; National Institute for Occupational Safety and Health (NIOSH) 1978; Sax 1968; USEPA 1980; and The International

Technical Information Institute 1979).

Toxicity limits for chemicals for which guidelines are not provided are based on concentrations which produce no effects, or minor irritation not affecting mental alertness and physical coordination, assuming a 15-minute exposure time. In those

cases where appropriate human data are not available, animal toxicological data are used by applying a conservative factor of ten to lower the acute exposure limit. If information is not available for a certain chemical, data for structurally related chemicals within the same chemical family are used to set limits. In the absence of any specific information, the more conservative workplace limits suggested by the American Conference of Governmental Industrial Hygienists (ACGIH) (1980) are used.

The effect of an accidental release of each of the chemicals described in the previous section on control room habitability is evaluated by calculating toxic vapor concentrations inside the control room as a function of time following the accident. This calculation is performed using the conservative methodology outlined in NUREG-0570 (USNRC 1979), Toxic Vapor Concentrations in the Control Room Following a Postulated Accidental Release, and using the assumptions described in Regulatory Guide 1.78.

In a postulated accident, the entire contents of the largest single storage container are released, resulting in a toxic vapor cloud and/or plume which is conservatively assumed to be transported by the wind directly toward the control room air intake. In the case of the ConRail chemicals, the amount released is estimated as the quotient of the total tonnage shipped during the period and the number of carloads. A tank barge size of 1,450 tons and a maximum truck load of 25 tons are

assumed as the amounts released in accidents involving those means of transport. The formation of the toxic cloud or plume is dependent on the chemical nature and ambient BVPS-2 UFSAR Rev. 12 2.2-12 environmental characteristics. The entire amount of a chemical stored as a gas is treated as a puff or cloud which has a finite volume determined from the quantity and density of the stored chemical. A toxic substance stored as a liquid with a boiling point below the ambient temperature forms an instantaneous puff due to flashing (rapid gas formation) of some fraction of the stored quantity. The remaining liquid forms a puddle which quickly spreads into a thin layer on the ground, subsequently vaporizing and forming a ground-level vapor plume. A high boiling point liquid (above ambient temperature) forms a puddle which

evaporates by forced convection with no flashing involved. A more detailed description of the methodology used is provided in Appendix C of the Control Room Habitability Study (SWEC 1981a).

The calculations are performed by a state-of-the-art computer program which requires input information on the chemical's

physical properties, control room parameters, meteorology, distance from the spill to control room air intake, quantity of chemical released, and toxicity limits. For BVPS-2, control room parameters used as input include a ventilation rate of 200 ft/min, and a net free volume of 59,000 ft. The most conservative meteorological condition is assumed for the calculation, consisting of Pasquill Class G stability, coupled with a wind speed of 1.1 mph, and an ambient temperature of 104F. It is further assumed that the spill and control room air intake elevations are at ground-level and that the puff or plume centerline directly impacts the intake.

The results of the analysis are summarized in Table 2.2-11. This table indicates that 3 chemicals stored onsite, 1 chemical stored at BMP, 6 chemicals located at Arco Polymers, 94 of the 119 toxic chemicals shipped by ConRail, and 5 chemicals shipped by barge all have the potential to incapacitate the control room operators. In this context, a potential incapacitation is defined as a predicted toxic vapor concentration in the control room which exceeds the toxicity limit for more than two minutes. All of the Arco chemicals shipped by truck are predicted to have control room

concentrations less than toxicity limits and less than those stored at Arco and therefore they are not included in Table 2.2-

11. In addition, the chemical (ammonium hydroxide) stored at BMP

that would cause a habitability problem is a potential problem in regard to truck shipments as well.

The three onsite chemicals determined to cause a potential control room habitability problem include ammonium hydroxide, carbon

dioxide (CO), and hydrazine. There are several mitigating factors which preclude the likelihood of control room personnel incapacitation following a carbon dioxide, hydrazine, or ammonium hydroxide release.

Although the predicted CO concentration in the control room exceeds the stated toxicity limit (54.8 g/m), this limit is based on a 10-minute exposure for a worker to function without lapses in judgment. The next highest published limit is 91.3 g/m for a 30-minute exposure which causes intoxication. Therefore, the 67.4 g/m predicted concentration, which applies to a 2-minute exposure, is not likely to impair operator judgment based on the conservative exposure times which apply to the available toxicity information in comparison with the Regulatory Guide 1.78 2-minute exposure time. The predicted hydrazine concentration (0.24 g/m) is higher BVPS-2 UFSAR Rev. 0 2.2-13 than the stated toxicity limit (0.12 g/m). However, this limit is conservative for hydrazine because it is based on methylhydrazine, a more toxic alkyl derivative. Therefore, it is reasonable to assume that a control room operator can be exposed to a hydrazine concentration in excess of 0.24 g/m for the 2-minute exposure time specified in Regulatory Guide 1.78 without causing incapacitation.

The maximum ammonia concentration in the control room, predicted by the model, as a result of the evaporation of ammonia from an ammonium hydroxide spill, exceeds the toxic limit used in the analysis, assuming that the ammonia cloud moves directly toward the control room air intake. However, it is highly unlikely

that the ammonia cloud will reach the control room air intake due to its extreme buoyancy (ammonia being lighter than air). This effect has not been accounted for in the model. Buoyancy evaluations indicate that for every 5 meters of horizontal travel, the ammonia cloud will rise vertically 100 meters, assuming a horizontal wind speed of 1.1 mph. Therefore, since the storage location of the ammonium hydroxide is 200 feet from the control room air intake, it is concluded that the ammonia cloud will be well above the level of the intake vent at that

horizontal distance and will not affect control room personnel.

The results for the ConRail data, barge data, truck data, and offsite stationary sources are significant only in terms of a probability assessment, since the model assumes that a series of extremely unlikely events occurs in combination with one

another. For example, the predicted control room concentrations presented for the ConRail chemicals assume that the entire contents of a rail car are instantly released at the closest point to the site under design basis meteorological conditions, with the wind blowing directly at the intake. The corresponding impacts for smaller spills, greater distances, or under other

less conservative conditions will be significantly less.

BVPS-2 UFSAR Rev. 16 2.2-14 According to guidance presented in NUREG-0800 (USNRC 1981a), Standard Review Plan Section 2.2.3, and in Regulatory Guide 1.78, design modifications to warn control room personnel may not be required if all potential toxic chemical accidents and

other external man-induced events do not occur frequently enough to be considered design basis events. This frequency of occurrence is identified in NUREG-0800 (USNRC 1981a) Section 2.2.3 as 10 event per year, which is related to an event resulting in potential exposures in excess of regulatory limits.

Therefore, if the aggregate probability of occurrence of all ConRail, barge, truck, and stationary offsite toxic chemical releases which could incapacitate control room personnel is less than 10 per year, monitoring equipment for these chemicals is not necessary since the aggregate probability of a toxic chemical release resulting in exposures in excess of 10 CFR 100

guidelines is acceptably small.

In order to estimate the aggregate probability of operator incapacitation due to a ConRail or barge toxic chemical release, another computer program is used to sum the product of the various probability factors for those chemicals that have been determined to cause a potential habitability problem. These factors include the shipment frequency of each chemical, the frequency of an event causing a spill, the length of track or river length in each 22.5 sector where they pass within five miles of the site, and the frequency of winds blowing into the appropriate sector. Truck shipments are not considered in the probability analysis since they pose no habitability problem. (The shipment of ammonium hydroxide by truck is not a problem

due to its extreme buoyancy, as described previously).

The shipment frequency of each chemical transported by ConRail

is obtained from the ConRail node report (ConRail 1980). These values are linearly normalized to represent an annual frequency, since data are presented for an 18-month period. The frequency of barge shipments is estimated from the average yearly tonnage shipped by the large tank barges (vessel type 5) for the years 1977 and 1978, assuming a barge size of 4,500 tons each. The frequency of an event causing a spill is assumed to be 1.5 x 10 and 1.6 x 10 event per vehicle mile (frequencies presented in WASH-1238, Environmental Survey of Transportation of Radioactive Materials to and from Nuclear Power Plants, December 1972) for railroad and barge shipments, respectively. Track lengths and river lengths for the appropriate sectors are

developed from U.S. Geological Survey 7.5-minute topographic maps of the site area and are presented in Table 2.2-12, along with the frequency of winds blowing into those sectors based on 1976-1977 onsite meteorological data collected at the 35-foot level. The wind direction frequencies used in the analysis represent all wind speed and stability conditions, adding

another degree of conservatism to the evaluation.

BVPS-2 UFSAR Rev. 0 2.2-15 The result of the probability analysis is given in Tables 2.2-13 and 2.2-14. The aggregate probability of the 94 potential chemicals shipped by ConRail causing the incapacitation of control room personnel is calculated to be 4.2 x 10 per year, while the probability for the 5 barge chemicals is 0.8 x 10 per year. This results in a total probability of 5.0 x 10 per year for all the transportation sources that have the potential to result in a spill causing a control room operator incapacitation.

For the offsite stationary sources (Arco Polymers and BMP), an aggregate probability of operator incapacitation is calculated based on an accident event probability of 10 per year and wind direction frequency at the site. The 10 per year event probability is that suggested by the USNRC for stationary storage facilities. The wind direction frequency is obtained from three years (1976-1978) of onsite meteorological data and is determined for that wind direction range from each source which causes the toxic vapor plume to impact the control room air intake. This range of wind direction is based on the distance of the source from the intake and an assumed G-stability plume width of 2 standard deviations which encompasses 95 percent of the plume. These wind direction frequencies are determined to be approximately 0.020 for Arco Polymers and 0.016 for BMP. This results in an incapacitation

probability of 2 x 10 per year for each of the Arco Polymers chemicals and 1.6 x 10 per year for the BMP chemicals.

The aggregate probability for these sources is then calculated by multiplying the individual probabilities by the number of chemicals determined to cause a problem. In the case of BMP, one chemical, (ammonium hydroxide) is shown to exceed toxic limits. Since this chemical was shown to be of no concern from the onsite source due to buoyancy effects, there is no need to consider it in the offsite probability analysis. Therefore, the BMP chemicals do not contribute to the offsite probability.

Table 2.2-11 shows that six chemicals stored at Arco Polymers are potential problems for the control room operators. However, in all cases but one (toluene), predicted chemical concentrations in the control room are only slightly higher than the stated toxicity limits. Five of these toxicity limits (styrene, ethylbenzene, benzene, butadiene, and pentane) are

conservative in nature and can be exceeded by the margins predicted in this analysis without causing harm or incapacitation to the operators. In addition, it should be noted

that the upper limit of the stored quantity range provided by Arco Polymers (Table 2.2-10) is used in the analysis which further supports the elimination of these chemicals from the probability determination. Therefore, the aggregate probability for the Arco Polymers chemicals is based on one problem chemical (toluene) resulting in a value of 2 x 10 per year.

Therefore, the sum of the probabilities calculated for the four offsite sources is then 7.0 x 10 events per year.

Correspondence BVPS-2 UFSAR Rev. 18 2.2-16 with USNRC staff (1981b) revealed that a conservative factor of 10 could be applied to this value to identify the number of operator incapacitation events that in itself would result in

exposures in excess of 10 CFR 100 guidelines. Therefore, the probability of a toxic chemical spill resulting in unacceptable

exposures is correspondingly 7.0 x 10, which is less than the 10 event per year design basis probability objective.

The aggregate probability of an offsite source of toxic chemicals resulting in a loss-of-coolant accident in the event

of an accidental spill is less than the design basis probability

of 10 event per year identified in NUREG-0800 (USNRC 1981a), Section 2.2.3.

2.2.3.1.3 Fires

The production of high heat fluxes and smoke from fires at industrial or storage facilities, oil and gas pipelines, or transportation routes in the site vicinity does not present a hazard to the safe operation of BVPS-2. This is due primarily to the separation distances of these potential fires from the site. The nearest storage facility of large quantities of flammable materials is in Midland, Pennsylvania, which is about 0.5 mile from the site. The nearest truck route on which flammable materials may be transported (Route 168) is approximately 760 feet from the site. Large quantities of flammable materials are frequently transported past the site by rail (ConRail) and by barge. However, the separation distances of 2,100 feet for the ConRail line and 790 feet for barge

traffic at the closest points of passage from the site are sufficient to prevent any hazardous heat fluxes or smoke plumes

from reaching the station in the event of an accidental fire.

In addition to the mitigating effect of the separation distances

of potential fires from the site, the control room is equipped

with smoke detectors and manually operated intake dampers to identify and isolate outside smoke, respectively. These systems are described in detail in Section 9.4.1.2.1.

Seven natural gas pipelines and seven petroleum product pipelines are located near the site, generally eastward of

BVPS-2. These buried lines are described in more detail in

Section 2.2.2.

The site is sufficiently cleared in areas adjacent to BVPS-2 such that forest or brush fires pose no safety hazards.

Likewise, onsite fuel storage fires do not jeopardize BVPS-2 safety since these facilities are designed in accordance with applicable fire codes. A detailed description of the BVPS-2

fire protection system is presented in Section 9.5.1.

BVPS-2 UFSAR Rev. 12 2.2-17 2.2.3.1.4 Collisions with Intake Structure As stated previously, the potential impact on BVPS-2 due to damage to the primary intake structure has been eliminated with the construction of an alternate intake structure which is capable of providing heat sink functions in the event of the loss of the primary intake structure. The postulated events which could damage the primary intake structure (gasoline barge impact and subsequent explosion) are discussed in Section 9.2.1.2.

2.2.3.1.5 Liquid Spills

Liquid spills from onsite and offsite sources are evaluated to determine the potential of such spills to be drawn into the intake structure or otherwise affect the safe operation of the

plant. There is a potential for liquid spills in the Ohio River to enter the plant's circulating water system via the intake structure and the service water system (SWS). A liquid spill from sources onsite is possible, but it is unlikely that a spill of this nature would affect safety-related equipment, be drawn into the intake structure, or otherwise affect the safe operation of BVPS-2.

Table 2.2-15 lists the liquids stored at the site, storage capacities, locations, and methods to contain or process overflow or spillage. Adequate protection is provided to minimize the effects of a spill on surrounding systems and equipment.

Table 2.2-16 gives the average quantities and types of liquids transported on the Ohio River per year. These values, as well

as commodities and amounts transported by the railroads, are tabulated in the Control Room Habitability Study for BVPS-1 and BVPS-2 (SWEC 1981a). Liquids transported by pipelines consist solely of petroleum products as indicated in Table 2.2-3. Relative locations of railroads and pipelines are shown on Figure 2.2-3.

Liquids transported by railroads and pipelines do not pose a serious threat of being drawn into the intake structure or to

the safe operation of BVPS-2.

Railroad service is provided by ConRail in the vicinity of the

BVPS-2 site; however, this line is of minor importance since it is controlled by the licensee and is limited to the servicing of the BVPS.

BVPS-2 UFSAR Rev. 13 2.2-18 The upstream release of oil or cryogenic liquids in the river due to either a pipeline rupture or a barge accident would not present a hazard to BVPS-2 operation, as these liquids would float on the river surface. The intake invert of the intake

structure is located more than 18 feet below the normal low water level of the river (Section 2.4.11.5).

Other liquids spilled into the river from a barge accident would be diluted by the river and would not pose a significant threat to BVPS-2 operations. In the unlikely event a coagulant liquid

enters the SWS, it would affect the discharge pressure of the SWS pumps and automatically start the standby service water pumps in the alternate intake structure in the event of low

header pressure.

Depending on the location of the accident and subsequent spill, the alternate intake structure may be used to provide safety-related cooling water from the standby service water system (Section 9.2.1.2). Located approximately one-quarter mile

upstream of the intake structure, the alternate intake structure is designed to accommodate BVPS-2 shutdown and cooldown after a postulated loss of the main intake structure.

2.2.3.2 Effects of Design Basis Events

Potential design basis events are identified in Section 2.2.3.1. The effects of potential accidents from present and projected industrial, transportation, and military installations and

operations have been evaluated as follows. Safety-related components and structures have been evaluated from the effects of these accidents and safe shutdown of BVPS-2 will not be

impaired.

Missile protection is provided for all components required to achieve and maintain a safe shutdown condition. Safety components are physically separated by barriers, located in individual cubicles, or located below grade so that a postulated

missile does not affect the components required for safe shutdown.

The redundant emergency diesel generators are completely independent satisfying the single failure criterion for safety-related equipment. This ensures that there are no effects from

fires on the emergency diesel generators.

An alternate intake structure is provided to ensure that safety-related cooling water is available in a postulated event where the primary intake structure is affected. These postulated events include damage from a gasoline barge impact/explosion (Section 9.2.1.2). The redundant intake structures ensure against loss of safety-related service water cooling in the event of a liquid spill in the river.

2.3.1 Regional

Climatology

2.3.1.1 General Climate 2.3.1.1.1 Types of Air Masses

The Beaver Valley Power Station - Unit 2 (BVPS-2) is located in a humid continental type of climate. The predominant types of air masses which influence this region are polar continental and maritime tropical. The polar continental air masses originating in Canada usually influence the region's climate during the winter, resulting in cold temperatures. Occasional outbreaks of arctic air masses during the winter bring extremely cold temperatures to the area. Maritime tropical air masses originating over the Gulf of Mexico usually influence the region's climate during the summer bringing

warm humid weather to the Beaver Valley Power Station (BVPS) area.

In general, the BVPS site experiences cool winters and moderately warm summers with ample annual precipitation evenly distributed throughout the year.

Table 2.3-1 presents the normals, means, and/or extremes of climatological data from the National Weather Service (NWS) Office at Greater Pittsburgh Airport, located approximately 16 miles southeast

of the BVPS site.

2.3.1.1.2 Regional Synoptic Features

In winter and early spring, the normal circulation over the region varies as eastward-moving migratory high- and low-pressure systems, identified with the mid-latitude westerly upper air circulation, alternately carry cold and warm air into the region. In the summer and early fall, the migratory systems are less frequent and less intense. Specifically, the summer and early fall climate of the BVPS region is influenced by the Azores-Bermuda anticyclone circulation, which is associated with extended periods of fair weather and periods

of air stagnation. Frontal activity, associated with the interaction of continental polar and maritime tropical air masses and migrating low pressure systems, predominates especially in the late fall, winter, and spring.

2.3.1.1.3 General Airflow Patterns

The orientation of the mountains in the area strongly influences prevailing winds in the region. The prevailing wind direction is from the southwest quadrant (National Climatic Center 1980). The wind speeds are moderate, averaging 9.3 mph, based on a 28-year period of record (Table 2.3-1). 2.3.1.1.4 Temperature and Humidity

Temperature patterns conform to the seasonal trends of the humid continental climate. The normal daily maximum and minimum temperatures for the region range from approximately 35 F to 21F in January and from 83 F to 61F in July, respectively. The mean annual number of days when the BVPS-2 UFSAR Rev. 0 2.3-2 minimum temperature is 0F and below is 5, while 124 days are 32 F and below. The mean annual number of days when the maximum temperature is 90F and above is 7. The mean daily temperature range in January is approximately 15F and in July 21F. Table 2.3-1 presents the monthly normals and extremes of Pittsburgh

temperature.

The highest relative humidity in the region generally occurs during the early morning hours of the summer and fall, frequently ranging between 80 and 90 percent (National Climatic Center 1980; Baldwin 1977). The lowest relative humidity in the region generally occurs during the early afternoon hours of the spring and summer, frequently ranging between 50 and 60 percent (National Climatic Center 1980; Baldwin 1977). Annually, the mean regional daily relative humidity is approximately 70 percent.

2.3.1.1.5 Precipitation

Precipitation is normally well distributed throughout the year, but monthly amounts are generally greatest in the spring and summer and least in the late summer, fall, and winter (National Climatic Center 1980). The maximum usually occurs in July in the form of thunderstorm activity. The minimum monthly precipitation usually occurs in February. The normal annual total precipitation expected for the region, which is site dependent due to local topographic influence, is approximately 36 inches. During the winter months, about one-fourth of the precipitation occurs as snow. Mean annual snowfall in the region is approximately 45 inches, based on a 25-year NWS period of record for Pittsburgh (Wallis 1978). Approximately 4 to 8 days per year, ice pellets and/or glaze (freezing rain) may be expected. Table 2.3-1 presents the monthly normal and extremes of precipitation for Pittsburgh.

Table 2.3-2 presents the expected rainfall in the BVPS area for various rainfall duration time periods and recurrence intervals (Frederick 1977; National Oceanic and Atmospheric Administration (NOAA) 1963). The expected rainfall amounts are generally less than amounts typical of the eastern two-thirds of the United States, especially those states located to the southeast, west, and southwest of the site.

Table 2.3-3 gives the maximum recorded rainfall for various rainfall duration periods at Pittsburgh (Jennings 1963).

BVPS-2 UFSAR Rev. 0 2.3-3 2.3.1.1.6 Relationships Between Synoptic and Local Meteorological Conditions The topography of the region strongly influences the climate at specific locations. The general orientation of mountain ranges in a northeast-southwest axis alters the synoptic wind flow. The higher mountain ranges which frequently prevent coastal storms from affecting the area also tend to cause greater precipitation east of the site region. The valley location of the BVPS site also favors the occurrence of nocturnal inversions due to cold

air drainage (NOAA 1974).

2.3.1.2 Regional Meteorological Conditions for Design and Operating Bases

2.3.1.2.1 Hurricanes

Hurricanes, or low pressure systems with a tropical origin, seldom affect western Pennsylvania, since this area is far inland and such storms lose force rapidly when deprived of their source of moisture (NOAA 1972). Consequently, if they penetrate the western Pennsylvania region, the hurricanes have degenerated with reduced wind speeds and diminished precipitation. In 1972, "Tropical Storm" Agnes, a downgraded hurricane, was the last major storm of tropical origin to influence the state of

Pennsylvania. Figure 2.3-1 shows the total precipitation induced by Agnes for the 6-day period in the state of Pennsylvania. The torrential rains were confined to the eastern and central parts

of the state, while the BVPS area received 4 inches or less. The worst impact of Agnes on the BVPS region was from stream flooding. However, at Pittsburgh, the Ohio River reached its

highest crest since 1942 (NOAA 1972).

2.3.1.2.2 Tornadoes

Regulatory Guide 1.76 has designated three tornado intensity regions in the continental United States and has promulgated a design-basis tornado (DBT) for each region (Markee 1974). BVPS-2 is located in Region I. As discussed in Section 3.3.2, the BVPS-2 design meets all structural requirements of the Region I DBT.

To determine the probability of a tornado striking a particular point in a given area, the following relationship may be used (Markee 1974).

p = n (a/A)

(2.3-1) where:

p = probability of a tornado strike in a given area BVPS-2 UFSAR Rev. 0 2.3-4 n = average number of tornadoes per year a = mean individual tornado path area A = total area in which the tornado frequency has been determined.

Based on data obtained from the National Severe Storms Forecast Center in Kansas City, Missouri, tornadoes occurring within the l-degree square for BVPS-2 were determined for the period 1950 through 1981. For the 32-year period, 39 tornadoes (1.22 per year) touched down within the l-degree square for the BVPS site (National Severe Storms Forecast Center 1982). The mean path area of the tornadoes was 0.4 mile. From Equation 2.3-1, the calculated probability of a tornado hitting the BVPS site is 1.4

x 10 per year, and the recurrence interval is 7.1 x 10 years. Table 2.3-5 lists each of the 39 tornadoes, including location of occurrence, path length, path width, injuries and deaths, and damage class. Damage class numbers range from 1 to 9 and provide an estimate of the damage according to Tables 2.3-6 and 2.3-7.

The columns labeled F, P, and P provide the Fujita-Pearson scale estimates of force, path length, and path width, respectively. All three scales are logarithmic with values ranging from -1 for the smallest category to +5 for the largest.

Table 2.3-7 shows the range for each scale. The path length and path width values represent estimates of the actual amount of

ground contact for each tornado.

2.3.1.2.3 Extreme Winds

The fastest-mile wind speed, which is a valid indicator of extreme wind, is defined as the highest speed of a 1-mile passage of wind, and is inclusive of all meteorological phenomena (extratropical cyclones, thunderstorms, and hurricanes) except tornadoes.

The maximum fastest-mile wind speed recorded at Greater Pittsburgh Airport from January 1945 through December 1980, as shown in Table 2.3-1, was 58 mph from the west, occurring in February 1967 (National Climatic Center 1980). Historical records dating back to 1870 do not indicate any fastest-mile wind speeds that exceed the February 1967 value. The fastest-mile wind speed in Pittsburgh in the winter of 1978 occurred on January 26 (52 mph) from the southwest. On this same day, the highest recorded hourly wind speed at the BVPS site was 43 mph

from the southwest at the 500-foot level.

The extreme wind at the BVPS site for a 100-year recurrence interval is 80 mph (American Society of Civil Engineers 1961). Discussion of this wind speed as a design basis is contained in Section 3.3.1.

BVPS-2 UFSAR Rev. 0 2.3-5 2.3.1.2.4 Thunderstorms Thunderstorms normally occur during all but the mid-winter months and have a maximum frequency in mid-summer (National Severe Storms Forecast Center 1982). The mean annual number of days with thunderstorms is 36, based on a 28-year period (Table 2.3-1).

2.3.1.2.5 Lightning

Seasonal and annual frequencies of lightning strikes to the reactor containment building have been estimated based on the frequency of thunderstorms in the BVPS site area and the structure's "attractive area". Since the attractive area of a structure is proportional to the magnitude of the lightning bolt's current, an estimate of the frequency of lightning strikes

was determined for lightning bolts having currents of 20, 40, 60, 90 and 135 KA. Table 2.3-8 provides a seasonal and annual summary of thunderstorm frequency and frequency of lightning

strikes, as well as the various attractive areas.

The reactor containment building is the largest safety-related structure, system, or component on the BVPS-2 site. Strike frequency estimates are provided in Table 2.3-8 to reflect lightning strikes to the containment building. All other safety-related structures would be subjected to lightning strikes on a less frequent basis than that reported for the containment building.

The lightning strike frequency calculation is based on the technique described by Marshall (1973). The average number of cloud-to-ground lightning strikes is calculated using the following formula:

NE = (0.1 + 0.35 sin) (0.40 0.20) (2.3-2) where: NE = number of flashes to earth per square kilometer

per thunderstorm day

= geographical latitude (for Pittsburgh = 40 30') To assure conservatism in the calculation, the term (0.400.20), is assumed to be (0.40+0.20), or 0.6. Therefore, for Pittsburgh, NE = 0.196 flashes/km per thunderstorm day. Multiplying this value by the seasonal and annual number of thunderstorm days at Pittsburgh, as taken from NUREG/CR-2252 (USNRC 1981), the number of seasonal and annual cloud-to-ground lightning flashes is determined as shown in Table 2.3-8. The attractive area of the containment building is determined following the technique of Marshall (1973):

K = R= (R= R) (2.3-2a)

BVPS-2 UFSAR Rev. 0 2.3-6 where: K = Total attractive area (m) R = Total radial distance (m)

R = Radius of containment building (m)

R = Radial distance to the edge of the attractive zone (m)

The parameter R is an increasing multiple of the building height (H) with increasing bolt current. According to Marshall (1973), R = 2H, 4H, 6H, 8H, and 10H for bolt currents of 20, 40, 60, 90, and 135 KA, respectively. Given a building height of 43.6 meters and a radius of 20.6 meters, the attractive area of the containment building is calculated for each of the five bolt

currents and presented in Table 2.3-8.

The number of lightning strikes to the containment building is then calculated by multiplying the number of cloud-to-ground lightning flashes/km/year by the attractive area of the containment building for each bolt current and then multiplying that product by the frequency of occurrence of each bolt current:

NS = NE x K x F (2.3-2b)

where:

NS = Number of lightning strikes to the containment building (strikes/yr)

F = Frequency of each bolt current (dimensionless)

Marshall (1973) assigns frequencies of 50, 22, 10, 2, and 0.5 percent to bolt currents of 20, 40, 60, 90, and 135 KA, respectively. The results of these calculations are given in Table 2.3-8. 2.3.1.2.6 Hail, Freezing Rain, and Ice Pellets

Annually, the mean number of days with hail in the region ranges between 2 and 4 (Baldwin 1977). In Pennsylvania, the months with high frequencies of occurrence of hail are May through July, with

the maximum frequency in July (Environmental Science Services Administration (ESSA) 1969). There were eight occurrences of hail 3/4-inch and greater in diameter reported in the l-degree square in which the site is located during the period 1955 to 1967 (ESSA 1969). The frequency of hail in the site area is significantly lower than that in the central United States. The severity of the hailstorms is also significantly less than in the midwest. A review of "Storm Data" for the period 1966 through 1980 indicates that of the cases reported, the largest hailstones were "golfball in size" for two cases occurring in Beaver County and Mercer County in August 1969 and July 1971, respectively (National Weather Records Center 1966 through 1975). The mean annual number of days with freezing rain (glaze) in the region is about 8 (Baldwin 1977).

BVPS-2 UFSAR Rev. 0 2.3-6a 2.3.1.2.7 High Air Pollution Potential The frequency of inversions is an important consideration in determining the dispersion capability of the atmosphere. Hosler (1961) has analyzed weather records of many U.S. meteorological stations in an effort to characterize regional atmospheric dispersion potential. The frequency of low-level inversions or

isothermal layers based at or below a 152-meter elevation in the site region is approximately 25 percent of the total hours on an annual basis. The seasonal frequencies of these inversions are approximately 18 percent in winter, 28 percent in spring, 25 percent in summer, and 32 percent in fall. The frequencies are relatively low compared to most areas of the United States and indicate a relatively high atmospheric dispersion potential in these areas.

Korshover (1976) investigated the occurrences of stagnating anti-cyclones in the eastern United States for a 40-year period. The seasonal distribution of atmospheric stagnation (4 days or more) in the BVPS region indicates that this region may experience 1 stagnation case during the winter (December, January, February), 2 stagnation cases during the spring (March, April, May), 18 stagnation cases during the summer (June, July, August), and 20 stagnation cases during the fall (September, October, November). The frequencies are relatively low compared

to most of the states in the southeastern United States.

2.3.1.2.8 Droughts

A drought is a period of abnormally dry weather which causes a serious hydrologic imbalance (American Meteorological Society 1959). The severity of a drought is difficult to assess because of the variations in precipitation patterns, degree of moisture deficiency, duration, and the size of the affected area. Dry spells which are not as severe as a drought are defined as periods of abnormally dry weather which may develop and persist for several months in the region. Occurrences of drought have not been reported for the period from 1938 to 1977; however, dry spells have been reported and can occur during any season in this region (NOAA 1974).

2.3.1.2.9 Snowfall The weight of the 100-year return period snowpack for the BVPS site vicinity is 19.5 lbs/ft (American National Standards Institute 1972). The weight of the 48-hour probable maximum

winter precipitation (PMP) for the site region is 71.2 lbs/ft based on a 48-hour PMP for a 10-mile area of 13.7 inches occurring in the month of March (Riedel et al 1956).

2.3.2.1.1 Wind Direction and Wind Speed Monthly and annual wind direction frequencies for the 35-foot, 500-

foot, and 150-foot levels for the period January 1, 1976 through December 31, 1980 are presented in Appendices 2.3C, 2.3D, and 2.3E, respectively. The 35-foot onsite wind data indicate that the winds

are primarily from the southwest. Secondary peak frequency from the southeast is associated with low wind speed as a result of the drainage wind. The 500-foot onsite wind data indicate that the winds are primarily from the southwest and are not influenced by the valley circulation.

Table 2.3-9 presents annual wind direction frequency information based on NWS data collected at Greater Pittsburgh Airport for the period January 1, 1976 through December 31, 1980 and for the period January 1, 1953 through December 31, 1980. Onsite wind data for the 150-foot and 500-foot level agree well with NWS data with some month-to-month differences. Differences in the 35-foot level wind data can be attributed to the wind sensor at Pittsburgh being located on a plateau above the river valley, effectively removed from the influence of the valley circulation.

Monthly and annual mean wind speeds for onsite data from January 1, 1976 to December 31, 1980 are compared with concurrent NWS data at

Pittsburgh in Table 2.3-10. Table 2.3-10 also gives the average monthly and annual wind speed data for NWS data at Pittsburgh from 1952 to 1980. Onsite wind speed data at the 500-foot level, which is

effectively removed from the valley circulation, and NS data agree well during the concurrent period and to the long-term period (1952-1980). Variations are primarily due to the differences in exposures

of the wind instruments.

Calms occurred 0.8 percent of the time at the 35-foot level and 0.2 percent at the 500-foot level from January 1, 1976 to December 31, 1980.

Wind direction persistence information for the BVPS 35-foot and 500-foot levels for the period January 1, 1976 through December 31, 1980 is presented in Tables 2.3-11 and 2.3-12, respectively. This same

information for Pittsburgh is presented in Table 2.3-13. At the 35-foot level, winds persist primarily from the north, northwest, southwest, west-southwest, west, and east-northeast, with a maximum

number of 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> from the southwest and the west-southwest.

The Pittsburgh wind direction persistence data for the same period show preferred wind persistence from the north, west-northwest, west, southeast, east, and west-southwest, with a maximum of 29 hours3.356481e-4 days <br />0.00806 hours <br />4.794974e-5 weeks <br />1.10345e-5 months <br /> from the north.

2.3.2.1.2 Ambient Temperature Monthly and annual means of ambient temperature at BVPS, based on onsite and Pittsburgh data recorded from January 1, 1976 to December 31, 1980 are BVPS-2 UFSAR Rev. 0 2.3-8 presented in Table 2.3-14. The monthly mean temperatures, based on onsite data, agree well with the average monthly mean temperatures, based on concurrent data for Pittsburgh and with the climatological normals. The annual average temperature for the period January 1, 1976 to December 31, 1980 at the 35-foot level was 49F. Monthly and annual extremes of ambient temperature for both onsite and Pittsburgh data are presented in Table 2.3-15.

The highest temperature recorded onsite was 94F and the lowest was -15F for the period January 1, 1976 to December 31, 1980.

Neither exceeded the highest and lowest temperature recorded at

Pittsburgh from 1952 to 1980. Monthly and annual average diurnal temperature variations for BVPS and Pittsburgh for the concurrent 5-year data period and for the long-term time period (1952-1980)

at Pittsburgh are presented in Table 2.3-16.

2.3.2.1.3 Atmospheric Water Vapor

Monthly and annual averages of dew point values and relative humidity calculated from recorded onsite measurements at the 35-foot level and from Pittsburgh are presented in Tables 2.3-17 and

2.3-18 respectively for the period January 1, 1976 to December 31, 1980. The data agree well and show slightly higher relative

humidities and dew points for the BVPS site than measurements at Pittsburgh. Table 2.3-19 presents the monthly and annual maximum and minimum dew point temperatures collected onsite from January 1, 1976 to December 31, 1980 and for the concurrent 5-year period and long-term period (1953-1980) from Pittsburgh. Monthly and annual diurnal dew point and relative humidity variations for BVPS

and Pittsburgh are presented in Tables 2.3-20 and 2.3-21, respectively, for the 5-year data period. Monthly and annual averages, extremes, and diurnal variations of absolute humidity

from onsite humidity measurements for the 5-year period are presented in Table 2.3-22. 2.3.2.1.4 Precipitation Monthly and annual averages and extremes of precipitation for t he BVPS site are presented in Table 2.3-23 for January 1, 1976 through December 31, 1980, along with long-term data from Pittsburgh. The average annual precipitation recorded onsite from January 1, 1976 to December 31, 1980 was 22.5 inches. This is less than the normal 36.2 inches for Pittsburgh. Monthly and annual averages and extremes of hours with precipitation and maximum 1- and 24-hour precipitation amounts are presented in Tables 2.3-24 and 2.3-25, respectively. The maximum amount of precipitation recorded onsite for a l-hour period was 1.47

inches, and the maximum amount of precipitation recorded BVPS-2 UFSAR Rev. 0 2.3-9 onsite for a 24-hour period was 2.39 inches. Snowfall is not measured onsite.

2.3.2.1.5 Fog

The BVPS site is located in a region where heavy fog occurs with relatively moderate frequency. Heavy fog can be expected to occur approximately 18 days per year (National Climatic Center 1980).

Fog occurs most frequently during late summer and fall and least frequently during the winter and spring.

2.3.2.1.6 Atmospheric Stability

Monthly frequency distributions of onsite T feet feet and T feet feet stability classes for BVPS are presented in Table 2.3-26 for the period January 1, 1976 through December 31, 1980. The predominant stability class for T feet feet is neutral and slightly stable with extremely unstable as a secondary peak. Neutral conditions are predominant for T feet feet. Table 2.3-27 presents monthly summaries of inversion durations for the BVPS site for the period January 1, 1976 to December 31, 1980 based on T feet feet. The longest persistence period of a T feet feet inversion occurred for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> in the month of January.

2.3.2.1.7 Monthly Mixing Height Data Mixing level is defined as the height above the surface below

which relatively vigorous vertical mixing occurs. Therefore, the mixing level indicates the practical vertical limit of dispersion and is significant for dispersion over large distances and for

cases involving significant plume rise. Monthly means of daily morning and afternoon mixing levels for Pittsburgh are presented in Table 2.3-28. The nearest NWS station to the BVPS site f or which the frequency of restrictive dispersion information is available is Pittsburgh. A total of 39 episode-days associated with 16 episodes was reported during a 5-year period (Holzworth 1972). These episodes occurred primarily during the autumn season. The frequency of occurrences of restrictive dispersion episodes at the BVPS site is not considered to differ significantly from those values reported for Pittsburgh.

2.3.2.2 Potential Influence of the Plant and Its Facilities on Local Meteorology

Plant construction activity such as tree removal and ground leveling, as well as the newly constructed plant buildings, switchyard gear, roads, and parking facilities is not expected to have a significant influence on the local meteorology.

The natural draft cooling towers at the site are expected to provide the only plant effluents capable of slightly influencing local meteorology. The cooling tower effluents of concern are commonly described as drift and visible plumes (fog). These effluents and their impact on local weather are described in the following subsections.

BVPS-2 UFSAR Rev. 13 2.3-10 2.3.2.2.1 Salt and Water Drift A mathematical model was developed to determine the downwind distribution of salt and water deposition rate and airborne salt concentration resulting from cooling tower operation. A detailed description of the model and modeling results are contained in Appendix 2.3A. The model takes into account the following:

configuration and performance of the to wers, drift rate, exit velocity, total dissolved solids level, droplet size distribution, evaporation rate, plume buoyancy, wind speed, wind direction, wet-

bulb temperature, and relative humidity. One year of onsite meteorological data (January 1, 1976 to December 31, 1976) was used in the drift model.

A maximum salt deposition rate of 9.9 pounds per acre per year (0.11 mg/cm/year) occurs approximately 4,750 feet east of the cooling towers. The maximum water deposition rate of 20,300 pounds per acre per year (227.3 mg/cm/year) occurs approximately 4,000 feet east of the towers. The maximum annual average airborne salt concentration is predicted to be 0.07 microgram per cubic meter

( g/m) (7 x 10mg/l) approximately 7,000 feet east of the towers, while the maximum hourly airborne concentration of 21.9 g/m (2.19 x 10 mg/1) occurs 3,250 feet west-southwest of the towers. These maxima are the largest values occurring over the entire spatial

grid of the model. Spatial averages of these concentrations are

not given, due to their insignificance in light of the small

impacts caused by the maximum values.

2.3.2.2.2 Visible Plume Occurrence

Ambient air becomes heated and moisture-laden when induced through natural draft cooling towers. This air is discharged from the towers as a plume, which may occasionally be visible. The extent and frequency of visible plume occurrence depend on the meteorological conditions existing at the time, and the design and

physical parameters of the tower.

A mathematical model, using as input simultaneous observations of wind speed, wind direction, ambient wet-bulb temperature, ambient dry-bulb temperature, and relative humidity, was used to determine the configuration and extent of visible plumes from the Beaver

Valley Power Station - Unit 1 (BVPS-1) and BVPS-2 natural draft cooling towers. Onsite meteorological data for the period January 1, 1976 through December 31, 1976, were used for the cooling tower

visible plume predictions.

The mathematical model used in this analysis is described in detail

in Appendix 2.3B.

The results of these model calculations are shown on Figures 2.3-2 , 2.3-3 , 2.3-4 , 2.3-5 , 2.3-6 , 2.3-7 , 2.3-8 , 2.3-9 , 2.3-10 and 2.3-11. The BVPS-2 cooling tower is situated close to the BVPS-1 tower and there will undoubtedly be some interaction of the two plumes. The state-of-the-art of plume modeling does not permit a realistic assessment of plume dynamics in such a complex situation with two towers of different emission characteristics. Therefore, the

plumes from the BVPS-2 tower have been shown separately from the BVPS-1 plumes.

BVPS-2 UFSAR Rev. 0 2.3-11 As can be seen from these figures, the plume rarely descends below heights of 250 feet. The plume remains aloft because it is initially injected into the atmosphere at a height of about 500 feet with an exit velocity of approximately 10 to 20 feet per

second, and is buoyant because its temperature exceeds that of the ambient air. Occurrences of visible plumes below the height of the tower are due to strong winds and the associated tower-induced turbulence in the wind field. Air traffic will be unimpeded by the cooling tower plumes.

2.3.2.2.3 Ground-Level Fogging and Icing Potential The visible plume rarely descends below heights of 250 feet above the ground. Thus, it does not impinge the ground surface, nor will it contribute to ground fogging or icing. Therefore, impacts to highway or river traffic are not expected.

To estimate the amount of ground icing due to the deposition of cooling tower water drift, the mathematical model described in

Section 2.3.2.2.1 was utilized, using as input those hours from the onsite meteorological data (January 1, 1976 through December 31, 1976) when ambient temperatures were less than or equal to

32F. Drift droplet distribution characteristics and predicted deposition rates are presented in Section 2.3.2.2.1. Conditions under which icing could take place occurred a total of 1,375 hours0.00434 days <br />0.104 hours <br />6.200397e-4 weeks <br />1.426875e-4 months <br />

based on 1 year of onsite meteorological data. Figure 2.3-12 presents the predicted spatial distribution of icing.

The maximum annual surface icing accumulation, which may occur due to cooling tower drift, is 0.024 inch. This is insignificant when compared with a "light" ice storm, defined as one that deposits

less than 0.1 inch of ice per hour (U.S. Government Printing Office (USGPO) undated). Furthermore, the maximum surface icing accumulation was conservatively estimated assuming that all

occurrences of freezing temperatures ( 32F) occurred consecutively.

2.3.2.2.4 Ambient Relative Humidity Increases The large amounts of moisture emitted from cooling towers not only contribute to visible plume formation, but also may increase ambient ground level relative humidities, even if the plume remains aloft. In order to evaluate the potential augmentation of ambient relative humidities due to cooling tower operation, a mathematical diffusion model, which incorporates tower-specific information and onsite meteorological data, was developed.

The model is based on the Gaussian diffusion equation for calculating ground level concentrations from an elevated buoyant

source, which is expressed as:

][])([D5.2x xhhh2/1EXP uQC X 2 z t ctzyvx w v (2.3-3) where:

BVPS-2 UFSAR Rev. 0 2.3-12 where: X = ground level concentration of water vapor (g/m) = increase in water vapor density (g/m)

C = time-averaging correction factor = 0.7 Q = emission rate of water vapor (g/sec)

= horizontal diffusion coefficient (m)

= vertical diffusion coefficient (m) u = mean wind speed (m/sec) h = cooling tower height (m) h = plume rise from cooling tower (m) h = topographic height (m) x = downwind distance (m)

D = cooling tower exit diameter (m)

The term ][2.5Dx x geometrically accounts for initial dispersion from the area source of a cooling tower (virtual point correction to a volume source). The resultant increase in relative humidity can now be calculated from:

RH wwswT,T () (2.3-3a)

where: RH = relative humidity increase (percent)

= increase in water vapor density (g/m) = saturation vapor density as a function of ambient temperature (T) and wet-bulb temperature (T).

BVPS-2 UFSAR Rev. 0 2.3-13 Equation 2.3-3 is applicable to short-term concentrations only. For greater time periods, the water vapor concentration is sector-averaged according to the expression:

])([2 2 1 z t ct z v i whhh EXPxU Q N 2.032iij N (2.3-3b)

The plume rise from the tower is calculated using Briggs' plume rise equations (Appendix 2.3A), and the dispersion coefficients and are obtained from Turner's (1969) curves. The hourly emission rate of water vapor (Q) is based on evaporation performance curves obtained from the cooling tower manufacturer.

The input data to the model consist of tower-specific information obtained from the manufacturers and 1 year of onsite meteorological data. For each hour of meteorological data, the ground-level water vapor concentration due to cooling tower operation is calculated at specific downwind intervals from the tower. The resultant increase in relative humidity is then calculated according to Equation 2.3-3a based on the ambient meteorological conditions for that hour. Annual, monthly, daily, and hourly relative humidity increases are calculated for each of

the sixteen 22.5 degree compass sectors.

The diffusion model was utilized to determine relative humidity

increases due to the operation of the BVPS-1 and BVPS-2 natural draft cooling towers at the BVPS site. One year (1976) of onsite data was used in the analyses. Also, the topography of the BVPS

region, obtained from U.S. Geological Survey maps, was used conservatively as input to the model by specifying the maximum height at l/2-mile intervals for each of the 16 downwind sectors.

The results of the analyses performed for the two cooling towers can be found in Table 2.3-29. This table presents the maximum

relative humidity increase for each of the 16 downwind sectors for the annual, monthly, daily, and hourly time periods. It is clear from this table that the cooling towers will have very little

effect on the ambient relative humidity levels. The worst hourly increase of 2.31 percent is small compared to ambient fluctuations of relative humidity. The reason for such a small increase can be

related to the large discharge height of the cooling towers (500 feet), which allows the moisture to effectively disperse before reaching the ground.

BVPS-2 UFSAR Rev. 0 2.3-14 2.3.2.2.5 Induced Precipitation One of the potential environmental impacts resulting from the discharge of cooling tower moisture is the regional augmentation of natural precipitation. Estimates of the total contribution to surface precipitation from cooling towers, based on a 2,200 MW station, would be only 0.4 inch annually (Huff 1972). This amount is inconsequential compared to the total annual rainfall (36.1 inches) experienced in this region (Section 2.3.1).

Induced snowfall due to operating cooling towers has been observed in West Virginia (Kramer et al 1976). However, the accumulation was found to be less than 1 inch of very light, fluffy snow.

Other documented induced snowfall occurrences generally preceded actual snowfall occurrences. An investigation into the climatic conditions conducive to induced snowfall indicated that a very cold, stable atmosphere with light winds optimized this situation.

It was assessed that this type of meteorological condition at BVPS is similar to that of the mountainous West Virginia region. Thus, an occasional induced snowfall of light fluffy snow may occur.

When compared to the large winter snowfalls experienced in this region (46.0 in/yr), this potential contribution is very small.

Therefore, there is no reason to expect that the proposed cooling towers would significantly alter local meteorology.

2.3.2.2.6 Cooling Tower Noise The hyperbolic natural draft cooling tower will be one of the dominant station operational external noise sources. Cooling tower and other operational noise sources are discussed in Environmental Report Section 5.6.

2.3.2.2.7 Synergistic Effects

Interaction between the saturated cooling tower plumes and local industrial emissions has the potential to form hazardous substances such as acids. High concentrations of sulfur dioxide emitted by fossil-fueled sources, in combination with the saturated cooling tower plumes, may result in significant catalytic oxidation of S0 tosulfuric acid. Droplet growth within the mixing plumes could also

BVPS-2 UFSAR Rev. 13 2.3-15 occur, resulting in an increase of ambient ground-level concentrations of sulfuric acid.

In order to assess the potential of the BVPS-1 and BVPS-2 cooling tower plumes interacting with stack plumes from nearby industrial sources, a detailed emissions inventory for the region was obtained from the Pennsylvania Department of Environmental Resources and used in a plume rise analysis to estimate the frequency of occurrence of plume intersection. This analysis involved calculating plume rises from each of the nearly 300 sources in the inventory, using a computer program which employs Briggs' plume rise equations (Appendix 2.3A) and onsite meteorological data. The plume trajectories were computed with those computed for the cooling towers, using 1 year (1976) of onsite meteorological data, and plume interaction occurrences were compiled. Based on the frequency of plume interaction and the emission rates of pollutants from the various sources in the area, only one stack plume warranted consideration for possible acid formation. This plume is emitted from the 950-foot stack at the fossil- fueled Bruce Mansfield Plant (BMP), located approximately 1 mile east- northeast of BVPS-2. The buoyancy, exit velocity, and emission height of the cooling tower plumes precluded

interaction with most other sources.

The potential for oxidation of S0 tosulfuric acid in the BMP plume, as a result of mixing with the cooling tower plumes, was examined in detail by determining the actual locations of plume centerline intersections in relation to the cooling tower visible

plume extents shown on figures 2.3-2 , 2.3-3 , 2.3-4 , 2.3-5 , 2.3-6 , 2.3-7 , 2.3-8 , 2.3-9 , 2.3-10 and 2.3-11. This was accomplished by calculating centerline trajectories for the BMP stack plume and the cooling tower plumes for each of 35 classes of wind speed and stability, and then determining the point of intersection for each class.

The frequency of occurrence of each wind speed-stability class was then computed based on 1 year (1976) of onsite meteorological data. For each of the seven Pasquill stability classes (A-g), the following five wind speed classes were chosen: 1 to 3, 4 to 7, 8 to 12, 13 to 18, and 19 to 24 miles per hour. Only the two wind directions which transport the plumes directly from the cooling towers toward the stack and vice versa were considered in the analysis.

Plume centerline interaction coordinates and frequency of occurrence for each wind speed-stability class are given in Tables 2.3-30 through 2.3-33. The interaction coordinates presented in these tables are applicable to both the BVPS-1 and BVPS-2 cooling towers since they are approximately the same distance from the BMP. The data presented in Tables 2.3-30 and 2.3-31 apply to the operation of either of two flues, labeled by the Pennsylvania Power Company as Source No. 31 and 32, and Tables 2.3-32 and 2.3-33 contain results for the remaining flue (No. 36). The calculations were performed in this manner due to differences in the flue gas flow rates from the BMP stack, depending on which

flues are in use, which affect the plume rise determination.

BVPS-2 UFSAR Rev. 13 2.3-16 According to the data presented in the tables, the cooling tower plumes intersect the BMP plumes most frequently at heights of approximately 400 to 3,000 meters above ground and at downwind distances of 50 to 1,500 meters from the stacks or cooling towers.

A comparison of these intersection points with the cooling tower visible plume frequency contours presented for the east-northeast and west-southwest wind directions on Figures 2.3-2 , 2.3-3 , 2.3-7 , and 2.3-9 indicates that the stack plumes intersect the visible portion of the cooling tower plumes for a maximum of 0.1 percent of the time in each wind direction, or approximately 18 hr/yr total. This low frequency of interaction can be attributed to the separation distance of 1 mile between the cooling towers and the BMP stacks and also to low frequency of occurrence of the

meteorological conditions which allow interaction to occur.

The increase in ground-level sulfate concentrations resulting from the interaction of the BVPS cooling tower visible plume and the BMP stack plume cannot be predicted accurately due to the large number of unknown variables. However, it is expected that any ground level impacts would be minimal due to the small amount of time over which these chemical reactions could take place. Ambient levels of sulfates at ground level due to stack plume

interactions with natural fog would far outweigh any contribution due to interaction with the cooling tower plumes.

2.3.2.2.8 Topographical Description The BVPS site is located on the south bank of the Ohio River, approximately 25 miles northwest of Pittsburgh, Pa. The normal pool elevation of the Ohio River at the site is 664 feet 6 inches above msl. The Ohio River Valley is sharply defined by the hills

and bluffs which extend to an average height of 400 to 500 feet above the river level within short distances of the river banks. The average width of the valley in the vicinity of the site is approximately 1,600 meters. The general topography of the site is shown on Figure 2.1-2. Topographic cross sections for each of 16 22.5-degree sectors radiating from BVPS-2 can be found on Figures 2.3-13, 2.3-14, 2.3-15, 2.3-16, 2.3-17, 2.3-18, 2.3-19, 2.3-20, 2.3-21, 2.3-22, 2.3-23, 2.3-24, 2.3-25, 2.3-26, 2.3-27 and 2.3-28.

2.3.2.3 Local Meteorological Conditions for Design and Operating Bases

Meteorological conditions considered for design and operating bases are regional in nature and are discussed in Section 2.3.1.2.

There are no other local sources of data that could be used for

design and operating bases. This is substantiated in the following discussion.

The design basis tornado parameters from Regulatory Guide 1.76 used in the design of BVPS-2 are extremely conservative. These parameters correspond to a scale 5 tornado on the Fujita-Pearson

scale which has not been observed within the l-degree latitude/longitude box for BVPS-2 over a 32-year period. The most severe tornado observed in this area was a scale 3 tornado on

May 13, 1956 which had an estimated wind speed of 158-206 mph. In

BVPS-2 UFSAR Rev. 13 2.3-16a addition, the calculation of the probability of a tornado strike at the BVPS-2 site was performed using the most recent data for the site area itself. Therefore, there are no other local sources of data on tornadoes which could be used for design and

operating purposes.

The design wind speed of 80 mph discussed in Section 2.3.1.2.3

is also a conservative value in that the observed fastest mile of wind at Pittsburgh over a 36-year period was 58 mph in February 1967. Mind speed data obtained at the site by the pre-operational meteorological program over a period of 5 years (1976-1980) do not indicate that an 80-mph wind speed is likely to occur since the highest hourly wind speed recorded at the 500-foot level was 43 mph. Although this is an hourly value, there is no reason to believe that a fastest-mile speed of 80 mph could have occurred during data collection at the site. In fact, the sheltering effects of the valley produce lower wind speeds at the site than those observed at the Greater Pittsburgh Airport, as shown in Table 2.3-10. Only the 500-foot wind speed measurements at the site indicate faster winds than at the airport. Wind speeds at the level of the containment dome (150 feet) are generally slower than those observed at the airport.

Therefore, locally obtained data do not indicate the need for a faster design wind speed than that addressed in Section 2.3.1.2.

There are no local data available on snowfall other than those obtained at the Greater Pittsburgh Airport. Since these data have already been factored into the isopaths of 100-year return period snowloads given in ANSI A58.1-1972, there are no other means of determining snowloads on a more local level. However, there are no special conditions at the site such as large water bodies or mountainous terrain to indicate that this estimate of snowload is inappropriate.

Since the PMP used in the calculation of the design flood is based on the theoretically highest possible precipitation amount in the area, local precipitation data are not needed in

assessing the design flood level.

No long-term data in the site area are available for the determination of a design wet-bulb temperature for the BVPS-2 cooling tower other than those collected at the Greater Pittsburgh Airport. However, comparisons of average dew-point

temperatures between those collected at the site for 5 years and those obtained at the airport indicate very little difference in atmospheric moisture between the site and the airport, as shown

in Table 2.3-20.

BVPS-2 UFSAR Rev. 8 2.3-17 2.3.3 Onsite Meteorological Measurement Program 2.3.3.1 System Description

The onsite meteorological program began on January 1, 1976. The 500-foot guyed meteorological tower is located approximately 3,600 feet northeast of BVPS-1. The base of the tower is at approximately 730 feet msl (223 meters). The meteorological monitoring system consists of two redundant trains of instrumentation located at three levels on the tower. Wind speed and direction measurements are made at elevations of 35, 150, and 500 feet. Ambient temperature measurements are made at the 35-foot level. Temperature differential measurements are made between 35 feet and 150 feet (T 150 feet-35feet) and 35 feet and 500 feet (T 500 feet-35feet). Precipitation data are obtained a few feet above the surface from a rain gauge near the base of the tower.

The tower is situated on a relatively flat plot of land in the Ohio River Valley and is enclosed by a fence. The ground surface in the immediate area is composed of slag and dirt.

Meteorological instrumentation includes:

1. Wind Instrumentation Wind direction and speed sensors at the 35-, 150-, and 500-foot levels.

2. Temperature Instrumentation

RTD temperature sensors in aspirated solar radiation shields at the 35-, 150-, and 500-foot levels.

3. Precipitation Instrumentation

Tipping bucket rain gauge at the surface near the tower. 4. Data recorders

5. Data collection and analysis computer.

6. Back-up diesel generator power supply.

The specifications for this equipment which follow the guidance of Regulatory Guide 1.23 and Appendix 2 of NUREG-0654 (USNRC 80) are summarized in Table 2.3-34. Monthly and annual joint frequency distribution tables for the 5-year data pe riod (January 1, 1976 to December 31, 1980) for T foot-foot and 35-foot wind, Tfoot -foot and 500-foot wind, and T foot-foot and 150-foot wind are presented in Appendices 2.4C, 2.3D, and 2.3E, respectively.

BVPS-2 UFSAR Rev. 8 2.3-18 The redundant meteorological instrumentation is located in an environmentally controlled shelter structure located near the base of the tower.

A data acquisition and dose assessment system is provided. This system meets the intent of the real-time plume trajectory and dispersion calculation requirements of Appendix 2 to NUREG-0654 (USNRC 80). This system is located in the Emergency Response Facility and is powered from redundant uninterruptable power sources. Terminals to this system, designated as the

Atmospheric Radioactive Effluent Release Assessment System (ARERAS), are located in the common U1/U2 control room, the Technical Support Center, the Emergency Operations Facility, and

at other onsite locations. From any of these terminals, users can display meteorological and radiological effluent data, and can run accident dose assessments using the real-time inputs.

Dial-up access is provided to state agencies. This system supplies data to the Emergency Response Data System (ERDS).

The meteorological data from the primary and redundant

meteorological instrumentation is obtained from redundant analog-to-digital conversion and multiplexing equipment, located

in the meteorological shelter, via redundant dedicated telecommunications lines.

The system polls meteorological sensors approximately every five

seconds and stores the received data in memory. Every 15 minutes, the 180 five-second samples for each sensor are

compared against statistical quality criteria to identify questionable or bad data, averaged, and then stored on magnetic media. The 15-minute average data for each primary and redundant sensor are stored (and are retrievable) individually. For wind speed and wind direction sensors, the average, minimum, and maximum value; the standard deviation; and a quality code

are stored for each 15-minute period for each sensor. For temperature, and differential temperature, the average value and a quality code is stored for each 15-minute period for each sensor. The stored data are periodically archived to magnetic tape for long-term storage. The archiving algorithm is structured to ensure that data for the most recent 14-day period

are retained online.

In addition to the 15-minute average processing, the data stored

for the 15-minute period which overlaps the start of each hour are also stored as hourly average observations. The data are periodically reviewed onsite and by an offsite meteorologist to

identify any anomalous condition or instrumentation problems.

BVPS-2 UFSAR Rev. 0 2.3-19 2.3.3.2 Meteorological Data Reduction The meteorological data acquisition system consisted of a computerized data processing system which collected and reduces data

on a real-time basis. The average wind direction, wind speed, temperature differential (T), ambient temperature, dew point, and total precipitation were determined for four 15-minute samples each hour. The sampling rate for each parameter for each level was approximately four times per second. Standard statistical equations were used to compute the 15-minute average values from the instantaneous samples. The standard deviation of the wind direction was calculated every 15 minutes with 10-second smoothing of the instantaneous wind direction.

In June 1985, the meteorological data acquisition system described above was replaced with a combined meteorological data acquisition

and dose assessment system. This system is described in Section 2.3.3.1. A statistical comparison of the data collected by the previous data acquisition system and the current system was

performed prior to the retirement of the previous system. The evaluation indicated that satisfactory correlations existed between the data collected by both systems.

The meteorological data acquisition system also includes an analog system as a backup to the digital system. When necessary to supplement digital data, the strip chart data were manually reduced. Hourly averages centered on the hour are obtained for temperature, dew point, and temperature differential (T) data. The precipitation trace records cumulative precipitation amounts and recycles every 15 minutes. Average values of the wind direction are obtained from 15-minute samples of wind data centered on the hour.

Hourly averages of 35-foot wind speed from analog data were electronically digitized to avoid human bias in the wind speed distribution for accident x/Q calculations. Atmospheric stability, based on the temperature differential, is classified according to USNRC Regulatory Guide 1.23. Table 2.3-35 presents the USNRC T stability categories.

2.3.3.3 Meteorological Data Recovery

Monthly and annual meteorological data recovery rates of combined analog and digital data for 35-, 150-, and 500-foot wind, T footfoot; T footfoot, 35-foot dew point, ambient temperature, and precipitation are provided in Table 2.3-36 for the period January 1, 1976 to December 31, 1980. Table 2.3-37 provides the monthly and annual data recovery rate for joint 35-foot wind and T footfoot and joint 500-foot wind and T footfoot from January 1, 1976 to December 31, 1980.

2.3.4 Short-Term (Accident) Diffusion Estimates 2.3.4.1 Objective

All accidents hypothesized for BVPS-2 are considered to result in ground level effluent releases from the containment structure. For various time periods after an accident, atmospheric dilution factors (x/Q) were calculated at the minimum distance to the BVPS-2

exclusion area and the low population zone (LPZ) (5,794 meters) for

each of the 16 downwind sectors.

BVPS-2 UFSAR Rev. 0 2.3-20 For the 0- to 2-hour time period (represented by 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> of meteorological data) at the exclusion boundary, the 0.5-percent and 50-percent sector-dependent x/Q values for each of the 16 downwind sectors are presented in Tables 2.3-38 and 2.3-38a.

2.3.4.2 Calculations The x/Q dilution factors presented in Tables 2.3-38 and 2.3-39 were calculated using the hi-variate normal or Gaussian diffusion model, modified for source configuration and lateral meander under neutral and stable conditions. Input parameters were determined from onsite meteorological data acquired during

the January 1, 1976 through December 31, 1980 period. These included the hourly-average values of wind speed and wind

direction at the 10-meter level, and atmospheric stability determined from the hourly-average values of temperature difference measured between the 10- and 46-meter levels.

Atmospheric stability was classified according to the temperature gradient values listed for the various Pasquill stability categories in Regulatory Guide 1.23.

Hourly-average x/Q values for the l-hour accident period (representative of the 0- to 2-hour period) were calculated from

the following equations from Regulatory Guide 1.145.

For Class D-G stability conditions, when the wind speed is less

than 6 meters per second (mps), 1 z 10 u Q y (2.3-4) where: yS,M 10 u y for distances up to 800 meters, and

For all Class A-C stability conditions, and for Class D-G stability conditions when the wind speed is greater than or equal to 6 mps, the greater x/Q value calculated from Equations 2.3-6 and 2.3-7 is chosen.

In the preceding equations, the parameter A corresponds to the minimum cross sectional area (1,600 m) of the containment structure, while and represent the standard deviations of plume concentration distribution in the horizontal and vertical

planes, respectively, with u representing the mean wind speed at the lowest (10 meter) tower level.

Each valid hour of the January 1, 1976 through December 31, 1980 onsite meteorological data was utilized for the calculation. An hour of data was considered valid if recovery of the 10-meter

wind speed, 10-meter wind direction, and 10- to 46-meter temperature difference was simultaneously accomplished. For the January 1, 1976 through December 31, 1980 period of BVPS-2, approximately 90 percent of the data fulfilled this criterion.

For each valid hour of meteorological data, a x/Q value was calculated with Equations 2.3-5 through 2.3-7 (whichever was applicable), where the wind direction determined the downwind

sector. In the calculation, the actual exclusion area or low population zone distances, as defined in Section 2.3.4.1, were used (along with the Regulatory Guide 1.23 stability class

typing scheme) to determine magnitudes of and according to the method outlined in Regulatory Guide 1.145, Revision 1.

For the hourly-average calm winds, a wind speed of 0.34 mps (instrument threshold) was assigned. Wind directions during calm conditions were assigned in proportion to the directional distribution of noncalm conditions bounded by a wind speed ranging from just above threshold to 1.5 mps. For the hours with variable wind directions, the last valid wind direction and

the actual recorded wind speed were coupled.

For each of the 16 downwind sectors, all nonzero x/Q values were stored and arranged in descending order, and the 0.5-percent values BVPS-2 UFSAR Rev. 0 2.3-22 were chosen. All 0.5-percent values were compared, and the sector with the largest x/Q value determined the ultimate design basis 0.5-percent sector-dependent x/Q value, for use in the Chapter 15 dose calculations.

The equation has been intentionally deleted from the UFSAR.

In 1996, short-term diffusion estimates were re-calculated using the USNRC computer code PAVAN. Input data were hourly

meteorological observations collected by the onsite meteorological monitoring program between 0000 1/1/86 and 2300 12/31/95. The 0.5% sector dependent and the 5% sector independent values defined in Regulatory Guide 1.145 were determined and are tabulated in Tables 2.3-38b and 2.3-39b.

Data recoverability during this ten year period was 99.6%. The minimum recoverability for any year in this period was 99%.

This re-analysis indicated a maximum 0-2 hour exclusion area boundary 0.5% value of 1.25E-3 sec/m (NW sector).

2.3.4.3 Main Control Room Short-Term Diffusion Estimates

The original licensing basis control room atmospheric dispersion factor (X/Q) values were calculated for both Units 1 and 2 using the methodology described by Murphy and Campe. Releases were postulated from each of the identified release points. The X/Q values were calculated to encompass 95 percent of the meteorological conditions (i.e., that are exceeded for only 5 percent of the meteorological conditions). Stability class G was assumed for conservatism. Adjustments for occupancy were included.

In 1991, the X/Q values for the control room were re-analyzed using a newer methodology outlined in NUREG/CR-5055. The updated X/Qs did not include adjustments for occupancy. In NUREG/CR-5055, Ramsdell considered the methodology of Murphy-Campe and proposed new methodologies to improve the predictive capabilities of calculations of atmospheric dispersion in the presence of building wakes. NUREG/CR-5055 reported on the results of seven field experiments that showed that the Murphy-

Campe methodology accounted for little of the variability in concentrations affected by wakes. An empirical model was proposed that showed a significant improvement in predicting centerline concentrations. The model, using multiple-variable linear regression, relates downwind distance, building cross-sectional area, wind velocity, and stability class to X/Q.

BVPS-2 UFSAR Rev. 16 2.3-23a Because circulation in building wakes distributes effluents entering the wake more widely than normal atmospheric diffusion, it was recommended that relatively wide wind-direction sectors (perhaps as wide as 90 degrees) be used in applying the methodology to evaluating concentrations affected by these wakes. In reports published subsequent to NUREG/CR-5055, Ramsdell generalized the statistical model into one that had comparable accuracy but had its basis in the physical mechanisms of

importance. The concentrations near the source were seen to be directly related to wind speed, rather than the inverse

relationship of previous models.

BVPS-2 UFSAR Rev. 16 2.3-24 For Beaver Valley, Halliburton NUS Environmental Corporation adapted the work of Ramsdell to the site terrain, plant configuration, and site meteorology. As the releases at Beaver Valley are low velocity releases, all were treated as ground level releases that were fully entrained in the building wake. For short-term averaging periods of eight hours or less, the methodology assumed that if the wind direction is within 30 degrees to either side of a line (effective centerline width of 60 degrees) between release point and control room intake, the plume centerline passed over the control room intake. For longer term averaging periods (e.g., 8-24, 24-96,96-720 hours)

a Gaussian distribution normal to the centerline was assumed.

On-site meteorological data for the 5-year period of 1986-1990 were applied along with the physical parameters appropriate for

each release point. Only 1% of the individual hourly data

contained any missing data. A sensitivity analysis of the input parameters was performed indicating acceptable model performance

[x].

As part of the plant modifications associated with containment conversion and core power uprate, the control room X/Q values were re-calculated using the latest version of the "Atmospheric Relative Concentrations in Building Wakes" (ARCON96) methodology. The control room X/Q values applicable to release points associated with an accident at BVPS-1 or BVPS-2, are presented in Table 15.0-14 and 15.0-15, respectively. The Emergency Response Facility (ERF) X/Q values for the environmental release paths associated with the Loss-Of-Coolant Accident are also provided. The X/Q values for all of the release-receptor combinations utilized to develop the post-accident control room operator occupancy doses are summarized in Table 15.0-15. The X/Q values for all of the release-receptor combinations associated with BVPS-1 accidents addressed in Table 15.0-14 are taken into consideration when the dose consequences of the event are established based on an analysis that is bounding for both units. Occupancy factors are not included.

Input data consist of hourly on-site meteorological data, release characteristics (e.g., release height and stack flow rate), the cross-sectional building area affecting the release, and receptor information (e.g., distance and direction from the release to the control room air intake and intake height). All input data for the ARCON96 runs were developed in accordance with draft NRC guidance on control room habitability assessments; Draft Regulatory Guide DG-1111, "Atmospheric Relative Concentrations for Control Room Habitability Assessments at Nuclear Power Plants," December 2001.

The ARCON96 methodology has the ability to evaluate ground-level, vent, and elevated stack releases and treats building wake effects and stable plume meander effects when applicable. This methodology is also able to evaluate diffuse and area

source releases using the virtual point source technique, wherein initial values of the dispersion coefficients are assigned based on the size of the diffuse or area source. The various averaging period X/Q values are calculated directly from running averages of the hourly X/Q values.

BVPS-2 UFSAR Rev. 14 2.3-24a A continuous temporally representative 5-year period of hourly average data from the BVPS meteorological tower (i.e., January 1, 1990 through December 31, 1994) is used in this calculation. Each hour of data, at a minimum, must have a validated wind speed and direction at the 10-meter level and a temperature difference between the 45- and 10-meter levels. The BVPS meteorological measurement program meets the requirements of RG 1.23 and Regulatory Position C.1.1 of RG 1.145 and is described in detail in Chapter 2.2.3.

All releases are conservatively treated as ground-level as there are no releases at this site that are high enough to escape the aerodynamic effects of the plant buildings (i.e., 2.5 times Containment Building height). The applicable structure relative to building wake effects on the releases is based on release/receptor orientation. The distances from the Unit 2 containment building edge to the receptors are determined from the closest edge of the containment building. The release elevations are set equal to the receptor elevations in cases where the releases are not from a clearly defined point, such as the containment edge releases. Where both the release and receptor are not clearly defined points, both elevations are set equal to grade elevation.

Only the containment edge release is considered to be a diffuse source as the release is from the entire containment surface.

Diffuse source treatment allows the calculation of initial values of the dispersion coefficients. These values are determined by the height and width of the containment building divided by a factor of six based on the draft NRC guidance on control room habitability assessments (NRC, 2001). All other releases are conservatively treated as point sources.

The ARCON96 default wind direction range of 90 o, centered on the direction that transports the gaseous effluents from the release points to the receptors, is used in the calculation along with values for surface roughness length (i.e., 0.20 meter) and sector averaging constant (4.3) based on draft NRC guidance (NRC, 2001).

The control room air intake X/Q values are representative of the worst case X/Q values for control room unfiltered in-leakage purposes since the distances and directions from the release points to these receptors are very similar.

Control room tracer gas tests have indicated that a potential source of unfiltered inleakage into the control room during the post accident pressurization mode are the normal operation dampers associated with the control room ventilation system to which it is reasonable to assign the same X/Q as that of the Control Room air intake. The other source of inleakage is potentially that associated with ingress/egress and leakage via door seals. This inleakage is assigned to the door leading into the control room that is considered the point of primary access. This door is located in-between the BVPS-1 and BVPS-2 control room air intakes and is located close enough to the referenced air intakes to allow the assumption that the X/Q associated with this source of inleakage would be reasonably similar to that associated with the air intakes.

BVPS-2 UFSAR Rev. 16 2.3-24b The X/Q values at the ERF edge closest to Containment is conservatively assumed to be representative of the post-accident X/Q values to the Emergency Response Facility which includes the Technical Support Center (TSC) and the Emergency Operations

Facility (EOF).

2.3.5 Long-Term (Routine) Diffusion Estimates

2.3.5.1 Objective

Annual average and grazing season average x/Q and D/Q diffusion

factor estimates are calculated for each of the sixteen 22.5-degree sectors using methodology consistent with Regulatory

Guide 1.111, Revision 1. Table 2.3-41 provides the distances of the controlling maximum individual receptors. In accordance with the Annex to Appendix I, 10 CFR 50, the BVPS site must consider radioactive release sources from all reactors.

Therefore, diffusion estimates are provided herein for both BVPS-1 and BVPS-2. The five release points at BVPS and their

radioactive release frequencies are:

BVPS-1 Ventilation vent Continuous BVPS-1 Elevated release Intermittent BVPS-2 Ventilation vent Intermittent BVPS-2 Elevated release Continuous Combined BVPS-1 and BVPS-2 Continuous process vent

Release point design parameters are listed in Table 2.3-42, and

release point locations are shown on ER Figure 3.1-1.

The resultant x/Q and D/Q values for the three continuous release vents are calculated as discussed in Sections 2.3.5.2.2

and 2.3.5.2.3, respectively, and are listed in Tables 2.3-43 , 2.3-44 , 2.3-45 , 2.3-46 , 2.3-47 , 2.3-48 , 2.3-49 , 2.3-50 , 2.3-51 , 2.3-52 , 2.3-53 and 2.3-54.

The two intermittent release vents have identical x/Q and D/Q values. Methodology for estimating these diffusion factors is discussed in Section 2.3.5.2.4 and the results shown in Tables 2.3-55 , 2.3-56 , 2.3-57 and 2.3-58.

Annual average and grazing season average values of relative concentration are calculated for continuous gaseous releases of activity from the BVPS-1 ventilation vent, BVPS-2 elevated

release, and the process vent located on top of the BVPS-1 natural draft cooling tower, according to the straight-line airflow (Gaussian) model described in Regulatory Guide 1.111, Revision 1. The basic equation for this model is as follows:

])()([)()(2 k z k z e T 2 b 2 k z T k N1j,k 150 2 1 10 u hexpE1 0.5h u EXN 2.032 Q X 2 1 (2.3-10)

BVPS-2 UFSAR Rev. 0 2.3-26 Airflow reversals are accounted for by applying the terrain recirculation factor, , presented in Tables 2.3-40 and 2.3-59 for both ground and elevated releases at the site.

For vent releases occurring below the level of a nearby structure, 100 percent downwash (total entrainment) is conservatively assumed (E= 1). For vent releases occurring at a height that is twice the height of a nearby structure, downwash is precluded and the entrainment coefficient (E) is set equal to zero.

The process vent, attached to the BVPS-1 natural draft cooling

tower, is more than twice the height of the nearest adjacent solid structure, and is considered to be a totally elevated release. The BVPS-1 ventilation vent and the BVPS-2 elevated release are conservatively considered as ground-level release points although the releases are slightly higher than nearby adjacent solid structures.

Equation 2.3-10 was evaluated at the nearest site boundary, nearest resident, nearest vegetable garden greater than 500 feet, nearest milk cow, nearest milk goat, and nearest meat animal; all within 5 miles in each downwind sector. This evaluation was performed for each continuously emitting release

point. The annual average period is the January 1, 1976 through December 31, 1980 onsite data period, while the 6-month grazing season period is represented by the May 1 through October 31 period for each year of the 5-year meteorological data base.

The grazing season corresponds reasonably well with the growing season.

The effective release height was computed from the following equation:

pr ktrehhhh)( (2.3-11)

Values of topographic heights are conservatively assessed as the maximum height within a particular annulus-sector (annsect). An annsect is an area bounded by a 22.5-degree sector and any two radial distances from the release point. Plume rise for nonbuoyant sources was calculated by the following algorithm from Regulatory Guide 1.111:

1.7324. 2.3.5.2.3 x/Q and D/Q Modeling Techniques

Annual average and grazing season average depleted relative concentration values are conservatively assumed to be equal to annual average and grazing season average relative concentration values [x/Q = (x/Q)D], respectively. Therefore, no credit is taken for attendant plume depletion of radioiodines and

particulates.

Annual average and grazing season average relative deposition

values are calculated using Regulatory Guide 1.111 (Figure 6), with the following equation:

The methodology employed in the calculation of intermittent release x/Q and D/Q values is as follows (USNRC 1976):

1. One-hour sector-averaged x/Q values are calculated without terrain recirculation factors.

2. The 15-percent, l-hour value is plotted at 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> on log-log coordinates, while the annual average value is plotted at 8,760 hours0.0088 days <br />0.211 hours <br />0.00126 weeks <br />2.8918e-4 months <br />. A straight line, connecting the two points, is drawn.

BVPS-2 UFSAR Rev. 5 2.3-29 3. Log-log interpolation based on total ground intermittent release hours versus annual hours yields x/Q multiplier.

4. The multiplier is applied to annual average and grazing season average x/Q and D/Q values to obtain

intermittent annual average and grazing season average

x/Q and D/Q values.

NOTES:

• These columns indicate the sequence number and segment number of each tornado. Sequence numbers are assigned chronologically within each state. The first tornado in 1953 in Ohio is given sequence number 1 for the State of Ohio that year. Many tornadoes have more than one touchdown point; that is, they may touch down, lift from the ground, and then touch down again. These tornadoes are broken down into segments which are indicated by segment numbers. For a tornado with three segments, the sequence number stays the same but the segment number is different for each separate touchdown. The statistics in the tables are based only on the initial touchdown points. **This column indicates the aximuth and range from the center point.

SALT AND WATER DRIFT

BVPS-2 UFSAR Rev. 0 2.3A-1 APPENDIX 2.3A SALT AND WATER DRIFT As the normal service and circulating water flows through the fill section of a cooling tower, the impact of the falling water on the splash bars creates small water droplets, some of which are carried away by the air stream moving through the tower.

When these entrained droplets, called drift, leave the cooling tower, the exit velocity and buoyancy of the warm exit air provide the energy necessary to push the drift particles aloft. The downward force on the particles is the force of gravity, and its effect depends on the mass of the particles. Some of the

drift droplets exiting the tower are sufficiently small that gravitational forces on them are negligible and atmospheric turbulence dominates their movement. Other droplets are initially affected by gravity but partially evaporate so that they become affected primarily by atmospheric turbulence. Ambient temperature and moisture content determine the reduction of particle size due to evaporation, and the particle terminal velocity is governed by the particle size and the air viscosity. As the plume disperses and cools, the buoyancy in the plume is

dissipated, evaporation of the droplets begins, and a separation takes place between drift particles which will eventually deposit dissolved salts (salt drift) and water (water drift) on

the ground, and particles which will remain suspended.

A mathematical model was developed to determine salt and water drift deposition rates and to predict downwind suspended particulate concentration contributions from the cooling tower drift. A discussion of the mathematical theory employed, the

assumptions made, and the output of the model is presented as follows.

2.3A.1 Tower Performance The performance of the natural draft tower is determined by the

ambient air conditions. The air draft through the tower is induced by the density difference between the air inside and outside of the tower. Cooling tower performance data, defining the exit air volume for a given ambient wet bulb temperature and relative humidity, were obtained from cooling tower manufacturers. The volume of exit air is proportional to the ambient relative humidity and inversely proportional to the ambient wet bulb temperature.

2.3A.2 Drift Rate and Concentration The air flow through the tower entrains droplets formed by mechanical breakdown of the cooling water splashing through the tower fill. Those droplets that pass through the drift eliminators exit the tower as drift and contain the same

concentration of total dissolved solids as the circulating water. The total dissolved solids of the system represent the ambient dissolved solids in the makeup water concentrated by the evaporative cooling plus small chemical additions for biofouling control and pH adjustment. The drift rate is expressed as a percentage of the total cooling water flow.

BVPS-2 UFSAR Rev. 0 2.3A-2 2.3A.3 Droplet Size Distribution The drift droplets are not buoyant particles. They must be entrained by an air draft velocity at least as great as their fall velocity. The typical shape of the curve of the droplet size distributions above the drift eliminators has been obtained from two reports by the Jersey Central Power and Light Company Forked River (1972) and U.S. Environmental Protection Agency (USEPA) (1971) reports. It is approximated by the six classes of droplet sizes shown on Figure 2.3A-1. Each droplet class is expressed as a percentage of the total drift mass.

Once the distribution is calculated, it is assumed constant for that

specific operating condition. Air velocities increase beyond th e drift eliminators and should be able to support the same droplet sizes. There is also evidence that there is no appreciable droplet growth by condensation (Jersey Central Power and Light Company 1972) or decay by mechanical breakdown (USEPA 1971) to change the size distribution.

2.3A.4 Plume and Droplet Rise

The method for computing the plume rise from the natural draft tower is based on a set of equations developed by Briggs (1972). The symbols used are defined as follows:

h = cooling tower height (m) h = plume rise (m)

F = buoyancy flux (m/sec) _ u = average wind speed (m/s)

x = downwind distance (m)

S = stability parameter (sec) = Tz g = gravitational acceleration (m/sec) T = average absolute ambient air temperature ( K) = atmospheric vertical potential temperature gradient ( K/m)

= vertical temperature gradient between the 500-foot and 35-foot levels of the onsite

meteorological tower ( K/m) x x T z T z BVPS-2 UFSAR Rev. 0 2.3A-3 = dry adiabatic lapse rate ( K/m) x* = distance at which atmospheric turbulence begins to dominate entrainment (m) = 34 F/ For unstable or neutral atmospheric conditions:

h = 1.6 F/ x / u for x < 3.5x* (2.3A-1) h = 1.6 F/ (3.5x*) / U for x 3.5x* For stable atmospheric conditions:

h = 1.6 F/ u x/ for x < 3.14 u S/(2.3A-2) h = 2.4 F/ u/ S/ for x 3.14 u S/ For any calm condition near the ground, u is set equal to 1.0 m/s a value considered representative at the height at which the plume

will occur, and the preceding hourly wind direction is used.

The height of the plume above the ground at any given downwind distance is h + h. Since some droplets within the plume are sufficiently large so that they do not follow the centerline of the plume, the departure of

these droplets from the plume's centerline as a function of downwind distance was estimated.

The following equations were used (Briggs 1972):

r = 0.5z + r S = V x/u where r = radius of plume (m) s = droplet departure from plume centerline (m) x = downwind distance (m)

u = average wind speed (m/s) r = tower top radius (m)

BVPS-2 UFSAR Rev. 0 2.3A-4 V= fall velocity of droplet (m/s) z = rise for the plume centerline (m)

The droplet trajectories within the plume are computed. Should s become equal to r for specific large droplets, they would leave the plume and evaporation would begin at that height and distance downwind. Droplets remaining within the plume to the downwind distance of final plume rise are assumed to begin to evaporate at a height of h + h-S. 2.3A.5 Droplet Trajectory

When the droplets leave the plume, the droplet trajectory is determined by the horizontal wind velocity and the vertical droplet fall velocity. In general, smaller droplets are transported farther from the tower by the wind because they are carried higher by the cooling tower plume, and because their fall velocity is smaller. Larger droplets, however, do not rise as high above the tower and

fall closer to the tower. Evaporation decreases the droplet size and, therefore, the fall velocity. As a result, the slope of the droplet trajectory decreases until the equilibrium diameter is

attained, or until the droplet can be treated as a suspended particulate (diameter 50). 2.3A.6 Droplet Fall Velocity

The drift droplet falls at a terminal fall velocity where the vertical drag force balances the gravitational force; this velocity is largely dependent upon the droplet size. The fall velocity for a droplet smaller than 80 in diameter is computed from Stokes Law (List 1966):

vrgSS n2 2 9 12 (2.3A-6) where: V = fall velocity (cm/sec)

r = droplet radius (cm) g = acceleration of gravity (cm/sec)

S= droplet density (g/cm) S= air density (g/cm) n = dynamic viscosity of air (poise)

Since the air density is much smaller than the water density, the SSterm may be assumed equal to S.

BVPS-2 UFSAR Rev. 0 2.3A-5 The dynamic viscosity is independent of pressure except at very low pressures. the Sutherland equation describes viscosity as a

function of absolute temperature (List 1966).

n = dynamic viscosity of air (poise)

n (poise)

T = 296.16 K T = air temperature ( K)

C = 120 C (Sutherland's constant)

The terminal velocity for a droplet larger than 80 in diameter is based on the empirical results for distilled water droplets in

stagnant air (List 1966).

2.3A.7 Droplet Evaporation The mass evaporation rate of freely falling water droplets is expressed as the product of two terms: (List 1966) and (Figure

2.3A-2). ][][)()1(4ba K S Fr r dt dM (2.3A-7) where: M = mass (g)

t = time (sec)

r = radius of droplet (cm)

F = dimensionless factor

S = equivalent thickness of transition shell outside the droplet (cm)

K = coefficient of diffusion (cm/sec) saturated vapor density at the surface of the droplet (g/cm) ambient vapor density (g/cm)

BVPS-2 UFSAR Rev. 0 2.3A-6 Droplet evaporation is shown on Figure 2.3A-2 The first term in Equation 2.3A-7 is a function of droplet diameter and ambient air temperature. Since the effect due to ambient air temperature is slight, the factor is expressed in terms of droplet diameter at a mean temperature of 15C. The second term is a function of ambient air temperature and relative humidity. The evaporation is considered to be zero if the air temperature is below freezing or the relative humidity is above 98.6 percent (Jersey Central Power and Light Company 1972).

The evaporation of saline droplets is limited by the hydroscopic properties of the solution (Israel and Overcamp 1974). As water evaporates from a droplet, the concentration of the droplet solution increases. For high ambient relative humidities, evaporation ceases when the droplet vapor pressure reaches equilibrium with the atmosphere. Intermediate humidities allow the droplet to evaporate to a saturated or supersaturated solution. Under conditions of low humidity, evaporation occurs

until supersaturation, and the solution changes phase and crystallizes into a dry particle. Figure 2.3A-3 depicts the equilibrium diameter as a function of t he concentration of dissolved solids and the ambient relative humidity. The transition from droplet to dry particle occurs for relative humidities of less than 40 percent.

2.3A.8 Dispersion of Drift

Droplets larger than 50 in diameter were dispersed as described previously. In addition, the droplets were assumed to be

uniformly dispersed laterally across the downwind sector of 22.5 degrees. The drift mass is divided into six droplet size classes (Figure 2.3A-1) and the area of deposition for each si ze class is defined by the distances of deposit of the largest and smallest droplets contained in each class. The droplets of each class are assumed to be uniformly dispersed over the area of deposition for the class.

Droplets equal to or smaller than 50 in diameter, whether emitted initially from the tower or formed through evaporation of larger droplets downwind, were considered suspended particulates and were dispersed according to Gaussian principles (Israel and Overcamp 1974).

The total ground level suspended particulate concentration at any downwind distance is the summation of the contributions of all

droplet size classes which reach the 50 diameter cutoff. This cutoff was used to distinguish the suspended particulate portion of the drift from the salt drift deposition portion because a hi-vol sampler, the standard suspended particulate instrument, measures particles of this size magnitude. Furthermore, Roffman and Van Vleck, (1974) in a salt drift deposition review paper, refer to drift droplets that fall to the ground as having a diameter greater than 50 microns in diameter.

Airborne salt concentrations can be obtained by dividing the salt drift deposition rate from each of the six droplet size classes by the deposition velocity of the droplets (just prior to their

impact upon the ground) in the appropriate size class. The resultant sum of these "resuspended" settleable particulate concentrations and suspended particulate BVPS-2 UFSAR Rev. 0 2.3A-7 concentrations at each grid point constitutes the airborne salt concentration.

In the evaluation of the foliar salinization effects of airborne salt, the maximum hourly concentration at any point downwind is representative of the short-term period value, while the maximum annual average concentration at any point downwind is

representative of the long-term period value.

The amount of drift leaving the proposed cooling towers is

assumed to be 0.05 and 0.013 percent of the circulating water flow through the tower for BVPS 1 and BVPS 2, respectively. These numbers are guaranteed by the cooling tower manufacturers and, in fact, even lower drift rate percentages may be achieved.

The annual average TDS concentration in the blowdown and 1 year of onsite, hourly average meteorological data (January 1, 1976-December 31, 1976) were used as input to the salt drift model, which has been discussed within this section. Meteorological parameters used in the model were low-level (35 feet above ground) wet-bulb temperature and relative humidity to determine tower performance and upper level (500 feet above ground) dry-bulb temperature, wind speed, and wind direction to calculate droplet transport. The atmospheric stability parameter T feetfeet was also used to determine plume rise and droplet dispersion.

The results of the drift model are produced at 250-foot intervals out to a distance of about 5 miles from the towers in

each of the 16 downwind directions. Monthly and annual drift deposition rates are calculated at each grid point.

Surface areas affected by cooling tower salt drift and water drift for both units are shown on Figures 2.3A-4 and 2.3A-5 , respectively. The maximum salt deposition rate of 9.9 lb/acre/yr occurs approximately 4,750 feet east of the cooling towers. The maximum water deposition rate of 20,300 lb/acre/yr (0.09 in/yr) occurs at a distance approximately 4,000 feet east of the towers. The maximum annual average airborne salt concentration is predicted to be 0.07 g/m approximately 7,000 feet east of the towers, while the maximum hourly airborne concentration of 21.9 g/m occurs 3,250 feet west-southwest of the towers.

VISIBLE PLUME MODEL

BVPS-2 UFSAR Rev. 0 2.3B-1 APPENDIX 2.3B VISIBLE PLUME MODEL The mathematical model used to predict the configuration and characteristics of the visible plumes resulting from the operation of natural draft cooling towers is based on the work

of Fan (1967) and Abraham (1970). The basic assumptions and mathematical formulations of turbulent, round, buoyant jets are adopted and applied to determine the configuration of a visible cooling tower plume. The method takes into account the entrainment of the cooler ambient air, momentum of the balanced system, and buoyant force and heat content of the plume.

The governing equations, basic assumptions, and a definitive sketch for the turbulent jet method are presented on Figure

2.3B-1. The variables used in the equations of Figure 2.3B-2 are defined

as follows:

d = increment of distance along plume path (m) b = radius of plume jet (m)

U = horizontal wind velocity (m/sec)

V = vertical velocity of plume (m/sec)

= angle of plume trajectory with respect to the horizontal direction (degrees)

= entrainment coefficient for a momentum jet-constant (dimensionless)

= entrainment coefficient for a thermal-constant (dimensionless)

C = drag coefficient (dimensionless)

g = acceleration of gravity (m/sec) = density of ambient air (g/cm)

= density of plume (g/cm) x = horizontal coordinate of the plume centerline from the center of the tower (m) z = vertical coordinate of the plume centerline from the top of the tower (m).

A further discussion of plume predictions, with comparisons to observations based on photographs of emitted plumes from five natural BVPS-2 UFSAR Rev. 0 2.3B-2 draft cooling tower sites under varying meteorological conditions, has been published recently (Policastro et al 1977). In comparison with seven other models tested in this independent verification study, the model described above ranked second in its height predictions and third in its length predictions, with the best absolute log mean ratio. Based on these verifications, it is concluded that the overall configuration and size of cooling tower plumes are well simulated by the mathematical model used.

The turbulent jet method is based on the following assumptions:

1. Substitution of a mixing and entrainment mechanism for a dispersion mechanism, 2. Gaussian distribution for heat, mass density, and velocity profiles, and

3. Conservation of mass and momentum within plume boundaries.

As shown on Figure 2.3B-1, a round buoyant plume rises at a velocity, V, into ambient air with a velocity of U. The temperature and density of the plume at any given distance downwind, and the temperature and density of the ambient air, are represented by T, , T , and , respectively.

The trajectory of the plume is curved in the downwind direction due to the effects of a tower-induced low pressure region. The angle between the axis of the plume and the horizontal is . The entrainment, or lateral mixing of the surrounding ambient air, is balanced by deceleration of the entire central portion of the plume. Since these portions cannot be sharply defined, a local characteristic length, b, (linearly related to the standard deviation) is represented. The plume size is then calculated as 22b. The entrainment coefficients used for continuity of mass and conservation of momentum are those recommended by Abraham (1970). The effect of the presence of the pressure field can be lumped into a gross drag term proportional to the square of the velocity component of the air flow normal to the plume axis. The drag coefficient, C, is assumed to be a constant. Buoyant forces can arise due to density differences, whether they are due to plume temperature

or moisture content. The buoyancy of the cooling tower plume plays an important role in the analysis, since a large quantity of heat and moisture is rejected from the tower. The effects of

aerodynamic downwash are not included in the model due to the large emission height of a natural draft cooling tower which precludes downwashing of the plume.

Numerical analysis is used to solve the seven ordinary differential equations listed on Figure 2.3B-1. The parameters defining the visible plume behavior which is also depicted on Figure 2.3B-1 , are obtained from the solution of these equations.

Figure 2.3B-2 shows the predicted natural draft cooling tower performance curves (which are es sentially the same for both units),

BVPS-2 UFSAR Rev. 0 2.3B-3 assuming 100-percent heat load, which were used to develop Figures 2.3B-1 and 2.3B-2.

For given cooling tower operating conditions and specified meteorological conditions, the mathematical model calculates the size and configuration of the visible plume. The plume is visible as fog when the air in the plume is at or below its

saturation temperature. Ambient air at 100 percent relative humidity is not included as a given meteorological input to the model because it is assumed that fog occurs naturally during this condition. Based on 1 year (January 1, 1976 to December 31, 1976) of onsite meteorological data, 100-percent relative humidity occurred 5 percent of the time.

The mathematical model is constructed to accept input meteorological parameters grouped into the classes presented in

Table 2.3B-1 (ambient dry bulb temperature and relative humidity at 10 meters above ground level were used, as well as wind speed and wind direction at 150 meters above ground level).

Given the information in Table 2.3B-1, the model calculates the visible plume spatial extent in terms of plume length, trajectory, and radius for each combination of variables. These data are summarized for all meteorological combinations on a grid, whose dimensions are 1,500 feet (vertical) by 5,000 feet (horizontal), showing the frequency of occurrences of visible plumes by hours and by percent of total time.

The frequency of visible plume occurrence was calculated using all combinations of meteorological conditions (except 100-percent relative humidity) for each of 16 wind directions, utilizing the performance curves shown on Figure 2.3B-2 and based on a design wet-bulb temperature of 74 F. This is equaled or exceeded in 0.3 percent of the 1945 to 1977 Pittsburgh, Pa., observations.

2.4.1 Hydrologic

Description

2.4.1.1 Site and Facilities The Beaver Valley Power Station (BVPS) is located on the south side of

the Ohio River at river mile 34.7. The general site area is characterized by sloping topography, with the exception of the northeast corner of the site on which the station is located. Ground

elevations vary from 664.5 feet mean sea level (msl) (normal river pool elevation) to a maximum elevation of 1,160 feet msl. Station grades are approximately 730 to 735 feet msl. Peggs Run, a small

stream flowing through the eastern portion of the site, is channeled through a culvert near the station and enters the Ohio River just west of Route 168. Figure 1.2-1 shows the developed site. A complete description of the site is provided in Section 2.1. Figure 2.1-2 shows the hydrological features in the vicinity of the site.

All Seismic Category I structures are protected from the probable maximum flood (PMF) level of 730.0 feet as described in Section 3.4.1.

All safety-related equipment and connecting piping and wiring is either located above el 730.0 feet or adequately protected so that its function is unaffected by a flood to el 730.0 feet. Section 3.4.1 discusses flood protection for safety-related structures and

facilities.

2.4.1.2 Hydrosphere

The BVPS site is located on the south side of the Ohio River at river mile 34.7 at a location on the New Cumberland Pool that is 3.1 river

miles downstream of the Montgomery Lock and Dam and 19.6 miles upstream of the New Cumberland Locks and Dam. The total drainage area upstream of the site is approximately 23,000 square miles. The normal pool elevation at the site is maintained at el 664.5 feet msl by the New Cumberland Dam for river flows up to about 20,000 cubic feet per second (cfs). Figure 2.4-1 shows the major hydrological features in the region of the site. The loc al site drainage is discussed in Section 2.4.2.3.

2.4.1.2.1 Surface Water The Ohio River is formed in Pittsburgh, Pennsylvania, by the

confluence of the Monongahela and Allegheny Rivers. The Ohio River flows southwesterly for 981 miles to Cairo, Illinois, where it joins the Mississippi River. The river is highly regulated by many

reservoirs on its tributaries and by numerous navigation locks and dams. The navigation locks and dams on the Ohio River within 50 miles of the site are listed in Table 2.4-1, with their respective storage capacities. Table 2.4-2 lists the intakes (including their owners, locations, and rates of withdrawal from the Ohio River) that

BVPS-2 UFSAR Rev. 0 2.4-2 could be adversely affected by accidental release of contaminants. Tributaries within 50 miles of the site that have a mean flow greater than 100 cfs are listed in Table 2.4-3. The major tributaries are the Beaver, Allegheny, and Monongahela Rivers.

2.4.1.2.1.1 Beaver River

The Beaver River joins the Ohio River at river mile 25.2 on the Montgomery Pool, about 9.5 miles upstream of the site. The Beaver River at the Beaver Falls Gauge has a drainage area of 3,106 square miles with an average discharge of 3,530 cfs. The river basin contains eight major reservoirs, most of which are multi-purpose. The eight reservoirs are listed in Table 2.4-4, along with information on

owner, storage capacity, and use.

2.4.1.2.1.2 Allegheny River

The Allegheny River flows southerly from its headwaters in Potter County, Pennsylvania, approximately 270 miles to its confluence with the Monongahela River to form the Ohio River. The Allegheny River at the Natrona Gauge has a drainage area of 11,410 square miles with an average discharge of 19,270 cfs. The river has eight navigation locks and dams on the lowermost 72 miles. The Allegheny River Basin contains nine major reservoirs, many of which are multi-purpose. The East Branch Dam and the Kinzua Dam are equipped for low-flow

augmentation. These reservoirs are listed in Table 2.4-4 along with owner, storage capacity, and use.

2.4.1.2.1.3 Monongahela River The Monongahela River is formed at the confluence of the West Fork and Tygart Rivers. The river, which is divided into individual pools by nine navigational locks and dams, flows northward 128 miles to its confluence with the Allegheny River. The Monongahela River at the Braddock Gauge has a drainage area of 7,337 square miles with an average discharge of 12,260 cfs. The river basin contains three multi-purpose reservoirs located on the Tygart and Youghiogheny Rivers. The owner, storage capacity, and use of the reservoirs are listed in Table 2.4-4. An additional reservoir, proposed for the Cheat River at Rowlesburg, would add an additional 1,000 cfs during

extremely low flow conditions.

2.4.1.2.2 Ground Water

Ground-water conditions in the BVPS-2 site area are discussed in Section 2.4.13.

BVPS-2 UFSAR Rev. 17 2.4-3 2.4.2 Floods 2.4.2.1 Flood History

The greatest recorded flow on the Ohio River in the vicinity of the site occurred on March 15, 1936 (U.S. Geological Survey (USGS) 1978). The USGS gauging station at Sewickley, Pennsylvania, recorded a peak discharge of 574,000 cfs and a stage of 725.2 feet msl. As a result of flooding, an extensive flood control program for the Ohio River Basin was initiated to reduce peak stages and resultant economic losses. The Army Corps of Engineers now maintains 15 flood control projects above the site, all of which were built after the 1936 flood.

As indicated in response to Question 2.1 of the Beaver Valley Power Station - Unit 2 (BVPS-2) PSAR, the largest flood in recent history occurred in June 1972 due to Hurricane Agnes which produced a peak discharge of 370,000 cfs and a stage of 714.8 feet msl at the Sewickley Gauge. The reservoir system is credited for greatly reducing the impact of this flood.

2.4.2.2 Flood Design Considerations

The effects of flooding at the site were evaluated quantitatively for the following conditions: local intense precipitation, PMF on the Ohio River, potential dam failures, and ice effects. The design flood

elevation, derived from the PMF, is 730 feet msl.

In addition to the structural design of safety-related buildings to withstand a PMF level of 730 feet msl, the design of the intake structure also provides for protection against coincident windwave activity and associated wave runup as discussed in Sections 2.4.3.6, 2.4.10, and Licensing Requirements Manual LR 3.7.2 (Section 2.4.14). Section 2.4.2.3 demonstrates the design integrity of safety-related structures against flooding resulting from a local probable maximum

precipitation (PMP) event.

2.4.2.3 Effects of Local Intense Precipitation

The effect of local intense precipitation on the adjacent drainage area and the site drainage system were evaluated.

The all-season envelope PMP at the site, based on information from the U.S. Weather Bureau (1956), is listed in Table 2.4-5. The precipitation intensity was computed on the basis of a 10-square-mile area, since no variation is assumed between point and 10-square-

mile precipitation. For durations shorter than 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, the time distribution of 6-hour PMP was obtained from U.S. Army data (U.S.

Department of the Army 1965).

BVPS-2 UFSAR Rev. 0 2.4-4 2.4.2.3.1 Peggs Run The local watershed in which the site is located is shown on Figure 2.1-2. The watershed, with an area of approximately 4 square miles, is a hilly forested area, rising southward from the southern bank of the Ohio River.

The hills forming the small drainage course slope at approximately 2 horizontally to 1 vertically. The watershed boundary defines the area contributing runoff to Peggs Run which flows generally from south to north into the Ohio River and is approximately 3 miles long. The flow in Peggs Run is normally very low with a mean

annual flow estimated to be under 5 cfs.

A portion of Peggs Run (1,400 feet) is enclosed in a 15-foot-diameter culvert which connects to the culvert under the New Cumberland-Pittsburgh Railroad. Downstream of the railroad culvert, Peggs Run follows the existing stream bed for about 350 feet before entering a channel which connects to the Ohio River. The design flow of the 15-foot culvert is 2,000 cfs with a maximum capacity of 2,960 cfs. The small drainage area of Peggs Run makes it susceptible to a flash flood, which could occur during a period of low river stage. In order to determine the response of the watershed to a worst case of rainfall, a flood analysis was performed.

The analysis evaluates the effects of flooding due to local PMP and due to the flood of one-half of the local PMF in conjunction with a

safe shutdown earthquake (SSE). The 6-hour PMP having a maximum intensity of 9.3 in/hr for a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> duration is used to simulate the local PMF. In both cases, the 15-foot-diameter culvert in Peggs Run is assumed to pass negligible flow, due to blockage by debris or seismic failure. The general approach taken is to route flow from contributing areas to the Ohio River and to compute the resulting

maximum water depth at the safety-related structures. The U.S. Army Corps of Engineers HEC-2 water surface profile program (1980) is utilized to generate a series of water surface elevations. In both

cases, the resulting water levels in the vicinity of the safety-related structures are below the design basis flood of el 730 feet msl.

2.4.2.3.2 Site Drainage System

The 10-minute PMP having an intensity of 3.5 inches is chosen for evaluation. The distribution of a l-hour PMP down to a 10-minute duration is carried out following the same principle for distributing the 6-hour PMP down to the l-hour duration (U.S. Department of the Army 1965).

The storm drains are designed to pass, without flooding, a rainfall intensity of 4 in/hr. Site ground elevation surrounding all buildings is at or above el 730 feet msl with all safety-related building entrances set 6 inches above ground level, except for one door to the service building where the sill is at grade. A runoff analysis was performed for the 10-minute period of highest BVPS-2 UFSAR Rev. 0 2.4-5 precipitation intensity (21.0 in./hr). The yard drains are assumed to be ineffective due to a concurrent high water elevation.

Roof drains are assumed to be blocked by debris. Critical flow paths and contributing drainage areas were determined using roof plans and site drawings containing topographic information. Peak water surface elevations along the flow paths were computed using the HEC-2 program (U.S. Army 1980). The water depths adjacent to the openings of safety-related buildings are presented in Table 2.4-6. As shown in Table 2.4-6 the maximum water surface is above the sill of only one door to a safety-related structure. Since the sill to the affected door for the service building is at grade, runoff water from

local site flooding will seep under the door during the PMP until the site drainage system becomes operational or the water level dissipates.

An analysis was performed to calculate the quantity of water entering the service building under the affected door. HEC-2 runs were made using flows from time periods of the PMP less than the peak 10-minute intensity. From the water levels computed using HEC-2, an estimate was made of the quantity of water seeping between the bottom of the door and the sill. In the analysis, a maximum gap of 1/16 in. between the bottom of the door and the door sill was assumed. A door width of 8 ft and 1.5 in. thick was used. The flow rate was calculated by assuming laminar steady flow between fixed-parallel plates. In the most intense 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> rainfall, the water depths over the door sill varies from 0.2 to 0.5 ft. The total volume of water seeping through the door was calculated to be 475 ft. Taking into consideration the size of the room, equipment location, and with no credit taken for floor drains and sumps, the accumulation of water in the service building has been calculated to be 1.3 in. deep. Since there are no QA Category I equipment or electrical connections located closer than 2 in. to the floor, there is no impact on the operation of safety-

related equipment due to a PMP.

Since the intensity of winter PMP is only about half of the annual PMP

and the snow accumulation on the road will be plowed regularly, flooding at the site is not anticipated. Furthermore, the topography around BVPS-2 beyond the contour of el 730 feet slopes down sharply

toward the north and the east; therefore, even with ice accumulation on unplowed areas, the drainage in these directions would not be hindered. The access road on the southern side of the buildings will be plowed regularly and will provide drainage for storm flow from the west and the south of the buildings toward Peggs Run.

2.4.3 Probable

Maximum Flood on Streams and Rivers The PMF on the Ohio River has been evaluated by the U.S. Army Corps of Engineers, Pittsburgh District (1970). The Corps of Engineers concludes that the PMF has a peak flow of 1,500,000 cfs with an elevation of 730.0 feet msl at Ohio River Mile 35.0.

BVPS-2 UFSAR Rev. 0 2.4-6 The information presented in Sections 2.4.3.1 through 2.4.3.5 was obtained from the U.S. Army Corps of Engineers (1970) (Appendix 2.4A).

2.4.3.1 Probable Maximum Precipitation

The tributary area upstream of BVPS is adjacent to the Susquehanna River basin where a probable maximum storm has been previously

developed. This PMP study (U.S. Weather Bureau 1965) presented a storm pattern in the form of isohyetal lines developed for 24,100 square miles of drainage area in the Susquehanna basin above Harrisburg, Pennsylvania. This is about the same size as the area above BVPS. Consultation with the Office of Chief of Engineers, Army Corps of Engineers, and the Weather Bureau Hydrometeorological Section confirmed that data for the Susquehanna basin could be reasonably applied to the Pittsburgh area (U.S. Army Corps of Engineers, Pittsburgh District 1970).

Orientation of the storm pattern over the Pittsburgh District was performed by transposing it 2.5 degrees longitude west and 0.8 degree latitude south. This was believed to be not only a logical transposition, but also one conducive to the peak runoff maximization.

The isohyetal storm pattern is shown on Figure 2.4-2; the values of intensity and time distribution of the isohyets are presented in Table 2.4-7. 2.4.3.2 Precipitation Losses Being a summer-type storm, the PMF probably would occur when rainfall is normal or below normal. Antecedent stream flow would also be low and infiltration loss to runoff high. The infiltration rates computed for the high intensity storm of August 3, 1964, which occurred over the French Creek basin, were used in the PMP computations. This storm possessed typical antecedent characteristics from which the PMP storm is generated. These infiltration rates were applied to several high

intensity summer storms that occurred in or near the Stonewall Jackson Lake area, and the losses were found to be in close agreement with the actual losses. The infiltration rates used for the PMF are shown on

Figure 2.4-3.

2.4.3.3 Runoff and Stream Course Model

The sub-basin area is shown on Figure 2.4-4. The map has been subdivided into drainage areas. Each numbered area represents an uncontrolled area for which unit hydrographs have been established. Each shaded area is controlled by a dam and named accordingly. Except for Meander and Chautauqua, which are private, all of these dams are

operated by the Corps of Engineers. The different routing reaches used in the PMF analysis are indicated by letters. A separate tabulation of drainage areas is included in Table 2.4-8.

BVPS-2 UFSAR Rev. 0 2.4-6a Individual hydrographs for each of the 61 subareas in the basin and for the areas above the 13 reservoirs were developed from the unit graphs and the 6-hour rainfall values, applicable to the particular areas, modified by infiltration losses. These losses have been found applicable to storms of similar characteristics and seasonal occurrences in this area.

The reservoir inflow hydrographs were developed in a similar manner with unit graphs and the oriented rainfall values. In no case were these flood flows as great as the spillway design floods which were used to assure the safety of the dam against overtopping and failure. Reservoir storage during the early storm periods was sustained long enough to permit downstream passage of the flood peak before spillway discharge could appreciably add to its magnitude. Ultimate reservoir storage heights were below structural design levels.

The hourly unit hydrographic values and Muskingum routing coefficients cross-referenced to the area and reaches are presented as Table Response 2.10.2-1 in the BVPS-2 PSAR.

After the flow hydrograph for the PMF was computed, a stage-discharge relationship was developed which would accommodate this flow while maintaining all of the hydrologic characteristics. These characteristics require that the valley storage reflect the inflow and outflow into any reach and that the stage-discharge relationship

adequately represent the computed flows.

During analysis of a particular reach, the average volume within that reach (the average of the upstream and downstream stages) was the valley storage. Stage capacity relationships developed for these

BVPS-2 UFSAR Rev. 13 2.4-7 reaches determined a height equalling the maximum volume stored within that reach, which represents the difference between the inflow and outflow. A water surface profile was established from these computations (Figure 2.4-5). The slope of this profile was then inserted into Manning's equation along with the other known values to compute a discharge. This value was then checked against the P MF peak to satisfy all of the requirements. The Manning's roughness coefficient used and the basis for it is given in the response to U.S. Atomic Energy Commission (USAEC) Question 2.11.3 and is included in Amendment 4 to the BVPS-2 PSAR.

Figure 2.4-6 compares actual and reproduced Ohio River flow rates at the Dashields Lock and Dam during the October 1954 flood. Tabl e 2.4-9 presents one page of the flood forecast.

2.4.3.4 Probable Maximum Flood Flow

The uncontrolled area hydrographs routed to Shippingport resulted in a combined flood hydrograph of 1,430,000 cfs.

Reservoir outflows were subsequently routed downstream through the basin and were combined with the uncontrolled flow hydrographs to form

the PMF as modified by the 13 existing reservoirs.

This flood has a maximum flow magnitude of 1,500,000 cfs. It is almost 4 times as great as the maximum reduced flood of 200 years of record. The hydrograph of this flood is shown as Figure 2.4-7.

The analysis shows that outflow from the flood control reservoirs would only contribute 70,000 cfs to the flood peak. Reservoirs would operate according to their predetermined schedules and would be in no danger of failure since their own design criteria provide for flows of even greater magnitude.

None of the flood control dams are realistically expected to fail during peak flood flow, or at any other time.

2.4.3.5 Water Level Determination Using contour and profile data developed from Figures 2.4-8 , 2.4-9 , 2.4-10 , 2.4-11 , 2.4-12 , 2.4-13 and 2.4-14 , the U.S. Army Corps of Engineers (Pittsburgh District, 1970) determined that the PMF would

attain an elevation of 730.0 feet msl at Ohio River Mile 35.0.

2.4.3.6 Coincident Wind Wave Activity

An analysis of the coincident wind and wave activity during the PMF event was requested by the U.S. Nuclear Regulatory Commission (USNRC) during the BVPS-2 PSAR review. This additional analysis was performed in response to (USAEC) Question 2.13 and is included in Amendment 2 to the BVPS-2 PSAR.

BVPS-2 UFSAR Rev. 0 2.4-8 The following is a summary of that analysis:

1. The maximum wave height, H, is 5.0 feet with a wave period, T, of 4.0 seconds.

2. The maximum overpressure on a vertical wall due to wave action is 360 psf at the still water level.

3. The associated wave runup is 6.7 feet above the standing water level of 730 feet msl.

4. As discussed in Section 3.4, protection has been provided against wave action and there will be no loss of ability to maintain a safe shutdown condition.

2.4.4 Potential

Dam Failures, Seismically Induced

2.4.4.1 Dam Failure Permutations

An analysis of the seismically-induced flood potential was requested by the USNRC during the BVPS-2 PSAR review. This analysis is presented in response to USAEC Question 2.12.1 and is included in

Amendment 2 to the BVPS-2 PSAR. Detailed information including dam heights, long-term storage volumes and levels, flood control volumes and levels, and channel distances upstream of BVPS-2 for the major flood control reservoirs is presented in the response to USAEC Question 2.10.4 and is included in Amendment 2 to the BVPS-2 PSAR.

2.4.4.2 Unsteady Flow Analysis of Potential Dam Failures As discussed in the response to USAEC Question 2.12, contained in Amendment 2 to the BVPS-2 PSAR, and to Question 2.12.2 of Amendment 4, failure of the Conemaugh Dam (the most critically located dam with respect to flooding resulting from a dam failure) is not expected to

occur due to shear failure or liquefaction for either the 25-year flood plus the SSE, or the standard project flood (SPF) plus the historic earthquake. Even though the Conemaugh Dam has been analyzed to be safe against these loading conditions, it was assumed to fail coincident with the SPF. An analysis performed by the U.S. Army Corps of Engineers (Pittsburgh District, 1970) (Appendix 2.4A) shows that

the resultant peak stage at the site would be el 725.2 feet. This is less critical than the stage resulting from the PMF (el 730.0 feet), as discussed in Section 2.4.3.

Consideration was also given to the possibility of more than one dam failing. This situation could arise due to either seismically-induced

simultaneous failures or due to the failure of dams downstream from the flood wave caused by a single, seismically-induced upstream dam failure. All dams which could potentially affect water levels at the plant site are located on separate tributaries of the Ohio River. There are no dams in series on a single stream; thus, potential for cascade effects does not exist.

BVPS-2 UFSAR Rev. 0 2.4-9 All dams are designed to withstand an earthquake loading of O.lg horizontal, and safety factors indicate that these structures are safe against the postulated loading systems. Simultaneous failure of two or more dams under these conditions is not considered credible.

2.4.4.3 Water Level at the Plant Site

As discussed in Section 2.4.4.2, the failure of the most critically-located dam (Conemaugh) would result in a maximum water elevation of 725.2 feet at the site. In addition, multiple dam failures is not a

credible postulated event. The most critical flood condition at the site of el 730.0 feet results from the PMF, as discussed in Section 2.4.3. All safety-related equipment and connecting piping and wiring

are either located above that elevation or adequately protected so that their function is unaffected by a flood up to el 730.0 feet.

2.4.5 Probable

Maximum Surge and Seiche Flooding This section is not applicable to the BVPS-2 site since the site is not located near a large body of water where surge and seiche flooding would be a significant consideration.

2.4.6 Probable

Maximum Tsunami Flooding A tsunami is a gravity wave system formed in the sea following any

large scale, short duration disturbance of the free surface. Tsunamis usually occur following undersea earthquakes of a certain magnitude, although landslides, bottom slumping, and volcanic eruptions have

generated tsunamis in certain cases. This section is not applicable to the situation at the BVPS-2 site.

2.4.7 Ice Effects 2.4.7.1 Potential Ice Jamming

The statistical summary of ice in the Ohio River at Cincinnati, Ohio for 1874 - 1964, prepared by the National Weather Service, is the most complete long-term record of icing on the Ohio River. This summary is regarded as a good average between the colder upstream reaches and the warmer downstream reaches by the Ohio River Division Ice Committee of the U.S. Army Corps of Engineers (1978). During the 90 years of record, 62 winters have experienced icing, including 13 winters when the river was frozen over and 28 winters which were ice-free. Table 2.4-10 provides a summary of the amount of time various degrees of icing were experienced.

Except for a 12-day period in February 1948, the longest periods of continuous river ice at Cincinnati occurred prior to 1919. As development of the Ohio River has increased, the influence of

reservoirs and of impurities on ice formation has increased, which may have contributed to shorter periods of continuous ice in more recent times. Frozen-over reservoirs will release warmer flows

BVPS-2 UFSAR Rev. 0 2.4-10 downstream than would have been released without the reservoir. Population and industry growth have increased the amount of impurities in the water, thus lowering the freezing point of the river.

Tributary storage reservoirs, however, trap some impurities, and recently there have been major efforts to reduce pollution, including waste heat. The net effect of these factors is unknown at this time.

Icing records at the New Cumberland locks and dam are maintained by the U.S. Army Corps of Engineers (1963-1979). The Corps has not, however, performed any special icing studies in the New Cumberland Pool, nor is it known whether ice conditions have caused lower or higher than normal water levels (U.S. Army Corps of Engineers, Pittsburgh District 1979). Available data for 1963 - 1979 are summarized in Table 2.4-11. Differences in definitions for various ice conditions prevent detailed comparison of the 17-year record at New Cumberland with the 90-year record at Cincinnati. It can be seen, however, that the majority of ice occurrences are, as expected, in January and February and that the average number of ice occurrences per year are similar, about 12 per year at New Cumberland and 15 per year at Cincinnati. The icing season is shorter at New Cumberland, perhaps reflecting the influences discussed in the preceding paragraph.

Of particular interest is the fact that the New Cumberland data show no occurrences of jamming or gorging or any reports of rising water levels due to ice buildup. Although the data indicate that navigation was occasionally delayed because of difficulty moving through thick ice or because of locking ice prior to locking traffic, there were no relatively long suspensions of navigation or damage to either the vessels or the locks and dam, such as were experienced at the Markland locks and dam in 1978. It appears that New Cumberland was able to

move ice through the locks and maintain sufficient traffic to prevent severe problems. The Ohio River Division Ice Committee Summary Report made the following comments which may explain the less severe difficulties experienced at New Cumberland compared to downriver reaches (U.S. Army Corps of Engineers 1978):

On the extreme upper portion of the Ohio and on the two streams that combine to form the Ohio; that is, the Allegheny and the Monongahela, significant ice is an every-year fact of life.

There are problems, but people expect them and have learned to cope with them with some degree of success. While temperatures in that area during the 1977 and 1978 ice periods were not as much below normal as in other portions of the Ohio basin, they were below normal. Even so, ice problems in 1977 and 1978 were essentially no different from any other year, largely due to

experience in coping with them. This was not the case elsewhere.

There is no reason to believe that operating procedures at the New

Cumberland locks and dam will not continue to be successful in preventing significant ice problems.

BVPS-2 UFSAR Rev. 0 2.4-11 The only significant occurrence of ice jamming in the plant vicinity was in 1936. At that time, all nonadjustable wicket-type gates on an old navigations dam were dropped to avoid damage by a large ice floe coming down from the Allegheny River. The resulting low pool caused

an ice jam with about a 5-foot rise in water level behind it. All of the old dams in this reach of the river have been removed. The New Cumberland Dam is now equipped with tainter gates, some of which are lowered to pass ice and then raised to maintain the normal navigation pool. Ice may also be passed through the locks. Thus, the circumstances of the 1936 ice jam cannot be repeated.

Although it occurred about 500 miles downstream of BVPS-2, the Markland ice jam of 1978 will be discussed since it was one of the most severe ice jams experienced on the Ohio River and because it occurred at a dam equipped with tainter gates. This ice jam caused considerable disruption of navigation as well as damage to vessels due to barges breaking free of moorings and piling against the dam and some gates becoming inoperable. An unusual combination of extreme meteorological events combined with less than optimum operating

decisions contributed to the difficult situation. The following description of the events at Markland is taken from a U.S. Army Corps of Engineers' Memo to Record (Whitlock 1978).

During mid- to late January, the lower Ohio River contained heavy ice, including considerable slush ice from tributaries. The river flow at that time was extremely low and the tainter gates at Markland locks and dam, all of which are non-submergible, could not be raised to pass ice. In addition, due to a coal strike and extreme cold, the hydroelectric station at the dam was operating at full power and this further decreased the amount of water available to move ice. The only recourse was to lock ice and barges through sequentially. The very heavy ice and some lack of coordination among industry, however, slowed traffic and made keeping the channel open very difficult. Simultaneously, an ice jam formed several miles upstream of the Markland Dam in a shallow bar area at a narrow point in the river.

Heavy precipitation, meanwhile, had begun causing a rapid rise in the river and associated flooding. The ice jam began moving and some barges moored upstream broke free. By the time Markland Dam had raised several gates to pass ice, a number of barges had already piled up on the dam and some gates were inoperable. Significant effort was

required to free barges and unjam gates to resume normal operations after the flood flows subsided.

The possibility of a Markland type ice jam forming on the New Cumberland pool is very low for the following reasons. First, the meteorological conditions which led to the Markland ice jam, extreme

cold and low flow followed by severe flooding, are extremely unlikely combined events. Second, some of the tainter gates at the New Cumberland Dam are submergible, permitting ice to be passed even during low flow periods. Third, an Ohio River Industry Ice Committee was formed following the Markland ice jam in order to ensure better BVPS-2 UFSAR Rev. 0 2.4-12 communication, operating procedures, and other measures to prevent a recurrence of the problems experienced at Markland.

The characteristics of the river in the vicinity of the plant also contribute to a very low possibility of an ice jam forming. Normally, ice jams form at obstructions and irregularities which do not exist at the vicinity of the intake structure, and there is no reason to

believe that the intake would ever be blocked by an ice jam. The Shippingport Bridge is located about 1,000 feet upstream of the intake, but its three pointed support piers do not form a significant channel obstruction. Thus, there is no reason to conclude that an ice jam would form there.

From the preceding discussion of historical events and the conditions in the BVPS-2 vicinity, it can be concluded that the formation of an ice jam that would cause a significant rise in the water elevation in

the New Cumberland pool or that would physically block the intake structure is extremely unlikely to occur. Thus, the present design of the station intake is adequate to assure BVPS-2 its required water

supply. 2.4.7.2 Potential Blockage of the Intake by Ice

Blockage of the intake and thus the inability to supply BVPS-2 with sufficient water could occur by means of ice floes plugging the front of the structure or by formation of frazil or anchor ice on the bar racks or traveling water screens. Because of the relatively straight shoreline in the immediate vicinity of the intake and the fact that the intake withdraws water from el 646.0 to 659.5 feet msl, it is extremely unlikely that ice floes could pile up in such a way as to block a significant portion of the intake opening below the curtain wall (659.5 feet msl). In addition, the cleaning mechanism for the bar racks should remove ice just as it removes leaves, branches, and other debris should the broken ice floes pass through the intake opening and block the bar racks. The potential for frazil and anchor ice formation is a more complicated issue and is discussed in detail as follows.

Frazil ice formation takes place in the presence of supercooling, where the turbulence is too great to allow a surface sheet to form.

It first appears as finely divided colloidal particles which grow and cluster together, resembling cinders from which the French Canadian term "Frazil" has come into general use (Book 1948). Supercooling can result from rapid agitation through the action of the wind or through exposure in going through rapids (Book 1948). With respect to supercooling, precise temperature measurements made at the Holtwood

and Safe Harbor hydrostations in Pennsylvania showed that:

On the Susquehanna River, it has been found that frazil ice always forms when the river water becomes supercooled and that BVPS-2 UFSAR Rev. 0 2.4-13 supercooling occurs only when the rate of cooling is greater than 0.018 F/hr (0.01C/hr) within the temperature range 32.18 to 32.0 F (0.1 - 0.0 C). Cooling that occurs outside this temperature range is unimportant, and at cooling rates less than 0.018F per hour (0.01C/hr), a natural ice cover will form. Furthermore, experience shows frazil ice will not form once the ice cover has formed... It has also been noted that

frazil ice formation does not occur during daylight hours because of

the influence of solar radiation (80 Btu/hr/ft or 25 watts/m) (U.S. Bureau of Reclamation 1974).

Frazil ice crystals have a tendency to adhere to surfaces, such as metal trash racks, with a temperature equal to or less than the freezing point of water. The crystals can also clot together loosely in soft masses commonly referred to as slush ice. The term slush ice is also applied to a mixture of water and snow, either freshly fallen

or resulting from river ice break up.

Anchor ice, in contrast to frazil ice, does not form throughout the water body, but only on the bottom or on submerged objects near the bottom during periods of excessive radiational heat loss. Anchor ice could form directly on trash racks, or could accumulate on the racks after breaking loose from the stream bottom. Like frazil ice, anchor ice can build up and completely block an intake structure.

The potential for frazil or anchor ice formation in the vicinity of the station intake was examined. Since there are no rapids immediately upstream of the intake, only wind and/or a sufficiently rapid drop in air temperature could permit supercooling to take place.

There are no precise temperature data available for the Ohio River in

the station vicinity that is measured to 0.018 F or 0.01C/hr. Therefore, it was determined that experience would provide the best

indication of the potential for frazil ice formation.

A discussion with a member of the staff of the Cold Region Research Laboratory (1979) has indicated that no historic data exist on frazil ice formation for the Ohio River. Therefore, a telephone survey was conducted of facilities on the upper Ohio River which were reported by the Ohio River Valley Water Sanitation Commission (ORSANCO 1978) to have intakes on the river. This survey of icing problems is summarized in Table 2.4-12. A number of the facilities contacted have been using riverbank intakes equipped with trash racks and traveling water screens similar to the configuration of the BVPS intake. Some of these intakes had curtain walls, while others did not. In all cases, however, no problems with icing that prevented withdrawal of their required flow, due either to frazil ice formation or blockage by ice floes, were experienced (Duquesne Light Company 1980; American Bridge Company 1980; Jones and Laughlin Steel Corporation 1980; St. Joe Zinc Company 1980; Pennsylvania Power and Light Company 1980; Crucible Steel Company 1980; City of Wellsville

BVPS-2 UFSAR Rev. 13 2.4-14 1979; Crescent Brick Company 1980; Toronto Waterworks Company 1980: Toronto Titanium Metal Company 1980; Steubenville Water Plant 1980; Wheeling Pittsburgh Steel Corporation 1980; Mingo Junction Water Department 1983; Bellaire City Water System 1978; American Electric Power Fuel Supply 1983; Martins Ferry Sanitation Department 1979; and Ohio Edison Company 1980).

In particular, neither Beaver Valley Power Station - Unit 1 (BVPS-1), which has been operating since 1976, nor the neighboring Bruce Mansfield Plant (BMP), which has been operating since 1975 with a similar intake design, have experienced any difficulties related to icing. It should be noted that their operating experience includes the severe winters of 1977 and 1978.

Based on the review of experience at similar installations and consideration of conditions in the BVPS-2 vicinity, it is concluded that the proposed intake design provides sufficient protection against icing problems.

2.4.8 Cooling

Water Canals and Reservoirs Beaver Valley Power Station - Unit 2 does not utilize any safety-related cooling water canals or reservoirs. Therefore, this section does not apply to BVPS-2.

2.4.9 Channel

Diversions There is no potential for upstream diversion since the Ohio River

Valley is deeply entrenched in bedrock of sandstones and shales.

2.4.10 Flooding Protection Requirements

The PMF will not cause any safety-related structure, system, or component to lose its design function. The flood design basis is determined in accordance with Regulatory Guide 1.59. Sections 2.4.3 and 2.4.4 describe the flood and the resulting flood elevation. Flood protection of the site is discussed in Section 3.4.1.

Protection of the intake structure against coincident wind wave activity and associated wave runup is described in the response to USAEC Question 2.13 which is included in Amendment 4 to the BVPS-2 PSAR. The Licensing Requirements Manual ensures adequate flood protection for all safety-related systems, components, and structures when the water level of the Ohio River exceeds 695.0 feet msl at the intake structure. This requirement is discussed more fully in Section 2.4.14.

BVPS-2 UFSAR Rev. 15 2.4-15 2.4.11 Low Water Considerations 2.4.11.1 Low Flow in Streams

The New Cumberland Lock and Dam maintains the New Cumberland Pool at el 664.5 feet. Records indicate that this elevation can be maintained at flows up to 20,000 cfs as shown on Figure 2.4-15.

A low-flow frequency curve for the Ohio River at Shippingport is shown on Figure 2.4-16. This curve represents the lowest continuous 7-day mean flows that would occur. It is based on a statistical analysis of historical flows for the past 44 years (1929-1973) modified by the present reservoir system (U.S. Army Corps of Engineers, Pittsburgh District 1970). An instantaneous flow could be lower, but with the large impoundments behind the storage dams, the 7-day flow could be provided continuously by temporarily drawing on the river storage when

needed. Computerized models developed by the U.S. Army Corps of Engineers were used to simulate regulated stream flows in the Ohio River. Results of the analysis show that a minimum flow of 4,000 cfs would have occurred at the site during the record drought of 1930 with the contemporary

reservoir system. A design basis failure of the nearest downstream dam (the New Cumberland Dam) as described in 9.2.1.1.3 during minimum flow would result in a minimum water surface elevation at the site of 648.6 feet msl (U.S. Army Corps of Engineers, Pittsburgh District 1969, 1973). This minimum water surface elevation of 648.6 ft msl is considered to be the design level for BVPS-2. This is discussed in more detail in Section 2.3.4 of the BVPS-2 PSAR. Corps correspondence related to river flow and elevation is provided in Appendix 2.4B.

The USNRC, in its review of the BVPS-2 PSAR, indicated that, by extrapolating an unregulated low-flow frequency for drought conditions which may be characterized as the most severe reasonably possible at

the plant site, an instantaneous low flow of 800 cfs could occur.

Information received from the Corps of Engineers (1973) indicates that during any low flow period, including postulated flows as low as 800 cfs, navigation pools would not be intentionally lowered. Their analysis considered an extreme drought of 800 cfs coincident with the

loss of a lock gate, the only damage they felt could reasonably be expected to occur with this flow. The Corps stated that following loss of a lock gate, the bulkheads could be installed in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, during which time the pool would drop 1.8 feet to elevation 662.7 ft msl. Therefore, the postulated flow of 800 cfs coincident with lock gate failure is less critical than a flow of 4,000 cfs coincident with

complete dam failure.

A Technical Specification, described in S ection 2.4.14 and earlier established in BVPS-l, requires that plant shutdown be initiated when the river level falls to 654 ft msl. The basis for the 654 ft msl shutdown elevation is described in Applicant Response to NRC Regulatory Staff Position 1 (07/19/73), BVPS-1 FSAR Question 2.14. The design minimum net positive suction head for the BVPS-1 raw water pumps, necessary for normal station operation, is reached at 654 msl.

BVPS-2 UFSAR Rev. 14 2.4-16 BVPS-2 does not have any equivalent to the BVPS-1 raw water pumps.

Even though the service water pumps in the primary intake structure are designed to provide adequate water for normal reactor shutdown down to 648.6 ft msl, shutdown is initiated at 654 ft msl.

2.4.11.2 Low Water Resulting from Surges, Seiches, or Tsunami

Because the site is not located on the coast or on a lakeshore, this section is not applicable to BVPS-2.

2.4.11.3 Historical Low Water

The lowest flow of record occurred during the extreme drought of 1930. A minimum of 1,250 cfs flowed past Shippingport in August of that year. Since that time, eight reservoirs with low flow augmentation

capabilities have been constructed. The lowest flow that would have occurred in 1930 with the contemporary reservoir system is 4,000 cfs.

2.4.11.4 Future Controls Several reservoirs in the authorized or planning stages would have a

substantial influence on low flows. Included in this group are Stonewall Jackson, Rowlesburg, and St. Petersburg Reservoirs. Collectively, they would increase the minimum flow to approximately

6,000 cfs at Shippingport.

2.4.11.5 Plant Requirements

The service water system (SWS) (Section 9.2.1) provides the safety-related source of cooling water to the various plant components requiring heat removal for ensuring plant shutdown and for the mitigation of accident conditions. The minimum required flow rates for safety-related components served by the SWS are given in Table 9.2-2. The SWS is also designed to provide the maximum normal operation flows as required to maintain plant operation. (Section 9.2.1).

The ultimate heat sink (UHS) (Section 9.2.5) is the Ohio River which provides the source of cooling water for the SWS. Section 2.4.14 describes the operation of the intake structure of the SWS during the worst case maximum and minimum river water levels.

BVPS-2 UFSAR Rev. 18 2.4-16a 2.4.11.6 Heat Sink Dependability Requirements

Cooling water for normal and emergency plant operation is provided by the Ohio River via the SWS. The Ohio River and the SWS combine to function as the safety-related means of heat

removal to maintain the plant in a safe condition following all

postulated events as described in Sections 9.2.1 and 9.2.5.

The SWS, as described in Section 9.2.1, is a safety-related Category I system designed and located in structures capable of withstanding the effects of natural phenomena, missiles, and pipe breaks. The system consists of three identical service

water pumps each of which is capable of minimum flow required

for safe shutdown following all unit operating conditions.

The service water pumps are located in and take suction from three separate cubicles of the intake structure. The intake structure elevation is chosen to provide satisfactory service

water pump operations at all river water levels, as described in

Section 9.2.1.

It is anticipated that silt will collect in the main intake structure. Therefore, as a minimum, the depth of silt in the intake structure bays will be measured semi-annually (twice in the period). Silt exceeding the 15-inch allowable level will be removed. The silt limit is 22 inches, as described in Section

9.2.1.1.3, so that a more than adequate water supply is ensured.

The Ohio River provides a continuous, inexhaustible source of

cooling, water, dependent only on operation of the SWS. Drift

and evaporation

BVPS-2 UFSAR Rev. 0 2.4-17 losses are insignificant and the maximum and minimum river water levels are evaluated as described in Sections 2.4.3 and 2.4.11.1 to ensure that the SWS pumps suctions are maintained full.

A standby service water system (SSWS) as described in Section 9.2.1, is provided to meet heat sink requirements when the Seismic Category I intake structure is not available. The SSWS

is designed to duplicate the cooldown capacity of the SWS to accommodate unit shutdown from 100-percent reactor power to cold shutdown conditions.

The SWS takes suction from the intake structure and discharges to the Ohio River. A study has shown that recirculation will not occur even during a design basis accident with a low river flow of 4,000 cfs and maximum heat rejection to the river.

The design basis hydrometeorology is as specified in Section 2.3.

2.4.12 Dispersion, Dilution, and Travel Times of Accidental Releases of Liquid Effluents in Surface Waters

2.4.12.1 Surface Water The refueling water storage tank (Section 6.2.2) was considered

for potential spills to the surface water environment. For the analysis, the tank was assumed to be initially 80 percent full.

The analytical technique used to determine dilution factors and travel times is the instantaneous release stream tube model described in USNRC Regulatory Guide 1.113. This technique uses the following equation in order to obtain downstream concentrations:

}{ttK4ut)(x expA)tK4(M C x 2 x 2 1 ])([B yncos B yncos BtKnexp21 s 2 y22 1n (2.4-1) where:

u = stream velocity

y = lateral location of source Dilution factors (DF) are then determined by:

where:

V = instantaneous volume released The river flow rate used in this analysis is 4,000 cfs. The longitudinal and lateral dispersion coefficients used are 4,740 ft/hr and 6542 ft/hr, respectively.

The longitudinal dispersion coefficient was determined from Regulatory Guide 1.113 to be:

K u*d 5.93 x (2.4-3) where:

u* = velocity shear R n 1.49 g u][6 1 n = Manning's roughness coefficient R = A/P = hydraulic radius

P = wetted perimeter of the cross section

d = depth The lateral dispersion coefficient was determined from Yotsukura and Sayre (1976) whose results have been adequately confirmed in field tests.

2 c][*u u r B 0.4d*u Ky (2.4-4)

BVPS-2 UFSAR Rev. 0 2.4-18a where: r = radius of curvature of river bends Yotsukura and Sayre report that the local values of K in meandering channels vary periodically in the longitudinal direction, usually reaching a maximum value of about twice the average in the downstream portion of the bend and a minimum of about half the average in the upstream portion. The reduction in the upstream portion is caused by the process of reversal in

the secondary circulation as the bend curvature is reversed. If bends are followed by short lengths of straight channel, the established secondary circulation is sustained throughout the straight portion of the channel. Thus, the longitudinal average of value of K is actually larger than that determined by Equation 2.4-4.

The analysis was performed for three downstream locations: Midland, Pennsylvania (1.3 miles downstream and 1,250 feet from the south river bank), East Liverpool, Ohio (5.2 miles downstream and 1,100 feet from the south river bank), and Chester, West Virginia (7.1 miles downstream and 30 feet from

the south river bank). The analysis indicates that the maximum concentrations (minimum dilution factors) are experienced at Chester, West Virginia. The minimum dilution factor and the corresponding travel time for the tank considered are given in Table 2.4-13. The effects of this analysis are discussed in Section 15.7.3.

2.4.12.2 Sediment Uptake Models

Sediment uptake reduces radionuclide concentrations in the water column as predicted by the transient source model utilized to predict far-field dilution factors. Because only limited information is available on sediment uptake, the effect of this process is conservatively neglected in the analysis.

2.4.12.3 Water Use Models There are no planned changes in water use or flow regulations in the Ohio River or adjoining tributaries that could have an appreciable effect on the far-field dilution estimate during the operating life of the station.

BVPS-2 UFSAR Rev. 0 2.4-19 2.4.13 Ground Water 2.4.13.1 Description and Onsite Use

2.4.13.1.1 Regional Aquifers The general geology of the area is described in Section 2.5.

Additional information on ground water may be found in BVPS-2 PSAR Section 2.4, and the responses to USAEC Questions 2.21-2.28 (Amendment 4) and Question 2.29 (Amendment 6).

The BVPS-2 site is located within the bedrock valley of the Ohio River on an alluvial terrace along the south side of the channel. Bedrock under the site consists of horizontally bedded shales with occasional sandstone and a few small coal seams, all of Pennsylvanian age. One thin limestone member, the Vanport limestone, outcrops in the valley wall south of the plant. The power station is located approximately 600 feet north of the south bedrock wall of the valley. At the plant location, bedrock is at approximately el 620 feet and drops only slightly toward the north where it underlies the river. It is overlain by a terrace of granular material which extends approximately to el 735 feet at the plant. The northerly portion of this terrace was eroded subsequent to its placement and replaced by recent deposits of the river in two low level terraces. These younger

terraces of silts and clays overlie the sands and gravels, which in turn rest directly on the bedrock.

The Ohio River at this location is controlled by a system of locks and dams for navigation purposes. The navigation pool at the site is normally held at el 664.5 feet.

The upland surface in the vicinity of BVPS-2 is above el 1,100 feet. The ground water in the bedrock underlying the upland surface occurs in joints and occasional permeable sandstone beds. Migration takes place along bedding and nearly vertical joint planes and along weathered zones. Water well records indicate that normal ground-water flow potential in these rocks ranges from less than 1 to about 10 gallons per minute (gpm) for each well, with 2 to 4 gpm as average. Sixteen seeps were

observed to originate from bedrock along the rock wall of the valley above the terrace during a survey undertaken June 13 to June 16, 1972; all but one seep were less than 1 to 2 gpm. The

remaining seep at el 900 feet, 4,000 feet southeast of the station, flowed at 4 to 5 gpm along shale joints overlying a confined sandstone bed.

The regional ground-water map (Figure 2.4-17) indicates that the ground water occurs under hydrostatic conditions with the phreatic surface having a contour in subdued relief approximating the land su rface. The topographic divides along the ridge crests also mark the local ground-water basin divides.

Ground-water level under the upland surface lies at depths of 10 to 50 feet below the surface, averaging 30 feet. The phreatic surface has a gradient of 50 percent

BVPS-2 UFSAR Rev. 0 2.4-20 on steep hillsides, 25 to 30 percent on gentler hillsides, and 15 percent or less along tributary streams. In all areas, the ground water flows downslope and eventually enters the terrace. Ground-water migration in the bedrock appears to be constant and slow. Due to the low permeability of the bedrock, recharge from rock to the terrace gravels is negligible. There are no known aquifers in the bedrock under the site.

2.4.13.1.2 Local Aquifer

Figure 2.4-18 shows the extent of the alluvial valley-fill deposits which form the terrace system along this portion of the

Ohio River as described in Section 2.5.4.

The terrace on which the station is located is about 4

,000 feet long and 1,800 feet wide at its widest point. The sands and gravels of this terrace form the only significant aquifer in the immediate site area. Both downstream and upstream of the station, the terrace pinches out against the steep bedrock

valley wall (Figure 2.4-18).

To the northeast of the station, ground-water flow is impeded by a buried structure, probably a bedrock bench which is suggested by the ground-water contours shown on Figure 2.4-17. This structure extends northwesterly almost to the river's edge at a point about 2,500 feet upstream of the station.

The terrace soils are predominantly sands and gravels except for

the overlying recent deposits of the clay and silt near the river. Section 2.5.4.6 discusses the observation that measured ground-water levels from piezometers in the plant area reflect changes in the Ohio River elevation with little or no time lag, suggesting good ground-water communication between the terrace soils and the river. Permeability of the sands and gravels was

determined from field tests as described in Section 2.5.4.6.

Recharge to the terrace aquifer in the site area is primarily from precipitation in the immediate area. Infiltration of about 35 percent (which would be expected for these soils, topography, and climatic conditions) would amount to an average infiltration of about 12 inches of water per year (about 900 gallons per day (gpd) per acre). Under normal river conditions, the ground-water levels under the terrace at the station location slope very gently towards the northwest as shown by the ground-water contours on Figure 2.4-17.

2.4.13.1.3 Onsite Use of Ground Water Two temporary wells onsite provided water for sanitary and

construction purposes during construction of BVPS-2. One of these wells had originally been drilled for use during construction of BVPS-1. Although the actual capacity of these wells is unknown, yields up to 300 gpm have been observed at each well. Domestic water for BVPS-2, the emergency response facility, and for other structures

BVPS-2 UFSAR Rev. 12 2.4-21 located to the east of Route 168 will be supplied by two wells (55 and 56) located adjacent to the emergency response facility. Water for BVPS-1 will be supplied by the intake on the Ohio River.

Two wells in the terrace gravels were drilled to supply cooling water (and augment the river water supply) at a rate of 300 gpm each to the Shippingport Atomic Power Station (SAPS, now decommissioned). This water supply is located close to the river (Figure 2.4-17).

2.4.13.2 Sources

2.4.13.2.1 Present Regional Ground-water Use Wells in the station vicinity are listed in Table 2.4-14. The location of these and approximately 43 additional domestic and farm wells is shown on Figure 2.4-17. These are mostly drilled wells, with a few old dug wells. Wells 16, 17, 18, 47, 48, and 49 are believed to be in alluvial deposits; all others are in

shale and sandstone bedrock. These wells were drilled prior to state law requiring filing of well logs (1966) and almost no data are available. In some cases, even though a well was not definitely identified, it was assumed that each house or trailer required a well.

As indicated in Section 2.4.13.1.3, the present ground-water use at the site is limited to two wells for SAPS (10 and 11) and two

construction wells (8 and 8A) for BVPS-1 and BVPS-2. Three wells (55, 56, and 57) have been drilled to supply domestic water to BVPS-2, the emergency response facility, and other structures to the east of Route 68. Well 57 has been capped due to low flow and at present there are no plans to make use of it.

The BMP is serviced by Wells 5, 6, and 9. The remaining wells in the area are used for residential water supply. Most of the wells are located on or upstream of the buried bedrock spur and are thus isolated from the site aquifer. Bedrock wells in the

upland areas are of low yield and all terminate at elevations well above yard elevation at the plant site.

A similar alluvial terrace is found on the north side of the river and slightly downstream from the plant site on which the town of Midland is situated (Figure 2.4-18). Ground-water data are not shown for this t errace since it is isolated from the plant site aquifer by the Ohio River which forms a ground-water

boundary.

2.4.13.2.2 Future Regional Ground-water Use

As described in Section 2.4.13.1.2, the only significant aquifer in the site area is a sand and gravel terrace overlying the site bedrock through which ground water interconnects with the river.

The terrace is about 4,000 feet long and up to 1,800 feet wide. It is limited by the steep valley wall downstream and a buried bedrock bench extending almost to the river's edge about 2,500

feet upstream. This bedrock

BVPS-2 UFSAR Rev. 0 2.4-22 and the surrounding upland region (above el 1,100) effectively isolate the terrace and directs ground-water flow toward the river.

Future ground-water use in the site region is expected to follow the existing pattern (Section 2.4.13.2.1). Shippingport Borough, in which the site is located, has no municipal water supply (ER Section 2.1.3) so future residential development will rely on wells for water supply. As discussed in Section 2.1.3, extensive residential development is not expected and, in addition, areas which are likely to be developed are located outside the site area aquifer. Thus, future domestic use of ground water should not be significantly different from present use. There are no known plans for industrial development in the site area. Future industrial use of ground water is expected to remain limited to the existing wells at SAPS, to those at BMP located about 6,000 feet upstream, and to wells 55 and 56 for BVPS-2 use.

Intrusion of river water into the aquifier, caused by excessive pumping on the site, would not affect any domestic

or industrial supplies because they all lie upstream and upgradient of the station site. Use of ground water at the site is not expected to deplete regional or local supplies because the alluvium is hydrostatically connected with the Ohio River which recharges the aquifier and prevents excessive drawdown due to well pumping.

The location of the station and the characteristics of the local aquifers ensure that any future development of ground-water resources in the site region would be either isolated from the ground water under the site or located upgradient of the station in the site aquifer.

2.4.13.3 Accidental Effects

2.4.13.3.1 Tank Failure and Dilution/Dispersion Modes As discussed in Section 2.4.13.1.2, all ground-water movement under BVPS is directed northwest toward the Ohio River. Ground-water migration is effectively blocked to the southwest where the alluvium pinches out against a bedrock cut scarp covered by relatively impervious colluvium just above river grade.

In order to evaluate the dilution and dispersion of an accidental spill of high level radioactive liquid waste to the ground-water system, a release from the BVPS-2 steam generator

blowdown (SGB) hold tank was postulated. This tank, which is housed in the waste handling building, could potentially hold 50,000 gallons of high-level liquid waste. Eighty percent of the tank's capacity was assumed to enter the ground-water system instantaneously upon tank failure. As shown on Figure 2.4-17, there are no down-gradient residential or municipal wells that could be affected by the postulated accidental release. Future ground-water use in the site region is anticipated to follow the existing pattern (Section BVPS-2 UFSAR Rev. 0 2.4-23 2.4.13.2.1). Therefore, the ground-water pathway to the nearest water user includes ground-water travel to the Ohio River and subsequent travel by the river to the nearest surface water user.

The minimum dilution factor and associated travel time for ground-water travel to the Ohio River due to the SGB tank

failure are 842 and 24 years, respectively. The surface water travel time is negligible compared with ground-water travel time. The total dilution factor for the ground-water path to the most critical water user (3.07x10) is equal to the dilution factor for the ground-water path to the river (842) multiplied by the dilution factor at Chester, West Virginia, due to the dispersion in the river (3.65x1O). The Ohio River and associated ground-water levels for this analysis were selected on the basis of annual average conditions. The river elevation was assumed to be 664.5 feet msl with an associated ground-water elevation of 665.5 feet msl.

All parameters utilized in the computation of dilution and travel time are presented in Table 2.4-15. The permeability of the in situ sand and gravel was estimated from field tests discussed in Section 2.5.4.6.

2.4.13.3.2 Vertical Travel and Horizontal Dispersion Source Configuration

The spill volume is conservatively assumed to enter th e ground-water system instantaneously upon the occurrence of a tank failure with an associated vertical travel time of zero. The

source configuration for the computation of horizontal dispersion is modeled as an instantaneous point source located in an aquifer of finite thickness. The source configuration for

the computation of dispersion in the river was simulated as a continuous vertical line source at the river bank.

2.4.13.3.3 Horizontal Dispersion and Travel Time The dispersion of the contaminant in the ground-water system was

modeled by the application of the solution obtained by Yeh and Tsai (1976) for transient, three-dimensional dispersion:

BVPS-2 UFSAR Rev. 0 2.4-24 Initial and boundary conditions are:

For an instantaneous point source release at the origin in a finite aquifer, the dilution factor DF is:

K = the horizontal permeability coefficient (ft/sec),

i = the hydraulic gradient (ft/ft).

The dispersion coefficients, K, K, K, are determined from dispersivity values as follows: The dispersion coefficient is a linear function of the dispersivity () and ground-water velocity (U), that is, (K= U). Longitudinal dispersivity () and transverse dispersivity () are related by the approximation = 0.3 (Brederhoeft and Pinder 1973). For the granular soils at the site, = . Robertson (1970) has referenced field data collected at the National Reactor Testing Station in Idaho near the Snake

River. Based on the best fit between field data and analytical solution along the centerline of dispersion, the

transverse dispersivity () of the Snake River aquifer was determined to be 59 feet. Robertson's field experimental results show that dispersivity varies with aquifer composition and that more permeable aquifers have higher dispersivity. If

one assumes that the properties of the aquifer

BVPS-2 UFSAR Rev. 0 2.4-26 (other than porosity) are similar, then the value of the dispersivity at the site may be estimated by:

n = the Snake River aquifer porosity = 10 percent, n = the porosity of the aquifer under consideration.

= the Snake River aquifer trans- verse dispersivity = 59 feet The coefficient of permeability measured for the granular soils at the site ranged from 5.7 x 10 feet per second (fps) to 2.00 x 10 fps. A value of 2.0 x 10 fps was utilized in this analysis as representative of the permeability along the pathway considered. The parameters used to determine horizontal dispersion and travel time through the ground-water system are presented in Table 2.4-15. 2.4.13.3.4 Sorption and Decay

The effect of these two processes was conservatively neglecte d in the computation of the dilution factor and associated travel

time.

2.4.13.4 Monitoring

In the event of radioactive materials spillage to ground water, no contamination of wells would occur, since there are no wells downgradient of the station, with the possible exception of SAPS wells 10 and 11. Since SAPS will be decommissioned by the time BVPS-2 is operational, no hazard is expected. Thus, monitoring of ground water to protect users is considered unnecessary and

is not provided.

2.4.13.5 Design Basis for Substructure Hydrostatic Loading

As concluded in Sections 2.4.13.1 and 2.5.4.6, the ground-water elevation at the plant site is assumed to coincide approximately with the Ohio River elevation. The following river elevations are possible at BVPS:

BVPS-2 UFSAR Rev. 15 2.4-27 Elevation Flood Stage (feet)

Normal Water Level 664.5 Ordinary High Water 675.0 25-Year Flood 690.0 Standard Project Flood 705.0 Probable Maximum Flood 730.0 Since monitoring river elevation began in June 1977, the maximum

level recorded was el 681.3 feet in February 1979. Ground-water data is presented in Appendix 2.5A.

All major buildings and structures are located or constructed so as to be unaffected by the SPF or lower flood stages. Any structure founded below SPF elevation is designed to withstand buoyancy and water pressure of the SPF and to be watertight and operative for that condition. The main intake structure is also designed for the water pressure and buoyancy of the PMF, assuming that one of the intake bays is dewatered during its occurrence.

Category I structures are designed to be watertight against, and to withstand the buoyancy and water pressure of, the PMF.

Hydrostatic pressure occurs only du ring flood stages since the ground water at the site is normally well below the founding elevation of all structures, except those located directly adjacent to the river.

Hydrostatic pressure combined with the lateral earth pressure produces maximum stress conditions in the containment walls.

Buoyancy of the containment is not a design problem, since the structure has enough dead load to balance the buoyancy due to a PMF. Flood stages and the wave resulting from a dam break

upstream are discussed in Section 2.4.4.

Liquefaction and dynamic settlement analyses are performed for Category I structures using as a minimum design the 25-year flood coincident with the SSE. These analyses are discussed in Section 2.5.4.

2.4.14 Technical Specification, Licensing Requirements Manual , and Emergency Operation Requirements

As discussed in Sections 2.4.2.2 and 2.4.11, the following Technical Specifications, Licensing Requirements Manual requirements, and associated plans of action are part of operational procedures. These specifications ensure a safe shutdown while an adequate water supply is available, and ensure the integrity of the UHS.

The PMF, with an associated water level of 730 feet msl (Sections 2.4.2 and 3.4.1), is the design basis for all safety-related structures. A requirement (derived from the response to USAEC Regulatory Staff Position 2), now located in the Licensing Requirements Manual , requires flood protection for all safety-

related systems, components, and structures when the water level of the Ohio River at the intake structure exceeds 695 feet msl.

BVPS-2 UFSAR Rev. 15 2.4-28 The dependability requirements of the UHS, as discussed in Section 2.4.11.6, are ensured as described by the following Technical Specification. This specification limits the operation of BVPS-2 to the conditions of the water level and

water temperatures of the Ohio River as follows:

1. A minimum water level at or above el 654 feet msl, at the intake structure, and

2. An average water temperature less than or equal to 89 F.

When the requirements of the above specification are not satisfied, the station is required to achieve hot standby within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and cold shutdown within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

APPENDIX 2.4A TECHNICAL REPORT ANALYSIS OF FLOOD HEIGHTS, OHIO RIVER AT SHIPPINGPORT, PA HYDROLOGIC ENGINEERING INVESTIGATION

Prepared by U.S. Army Engineer District, Pittsburgh, Corps of Engineers, Pittsburgh, Pa., January 1970

BVPS-2 UFSAR Rev. 0 2.4A-1 APPENDIX 2.4A ANALYSIS OF FLOOD HEIGHTS OHIO RIVER AT SHIPPINGPORT, PA.

Scope The proposed Shippingport Atomic Energy Plant site of the Duquesne Light Company is located on the left bank of the Ohio River, 35 miles below the head of the Ohio River at Pittsburgh, Pennsylvania.

The total drainage area of the river at this site is 22,989 square miles. Thirteen Federal reservoirs control flood runoff from 7,648 square miles of this area. The remaining area is 15,341 square miles.

Five additional Federal reservoirs which will control 1,367 square miles or about 9 percent of the now uncontrolled area

should be in operation within about 5 years.

Runoff from the 15,341 square miles below the existing dams will be virtually unaffected by any other structures during floods of maximum proportions.

The drainage area limits above the site are shown on Plate 1 as are the area's tributary to the 13 completed reservoirs and the 5 future reservoirs presently under construction or in an active

status for near future construction.

Actual Floods of Record Actual flood records in the immediate vicinity of mile 35.0 are only available since 1911. Comparable longer term records, however, have been obtained at Pittsburgh, Pennsylvania, 35 miles upstream and at Wheeling, West Virginia, about 52 miles downstream. The record at Pittsburgh dates back to 1762.

Continuous records, however, did not begin until 1854, thus providing 116 years of records available for mathematical frequency analysis but a record of 208 years for historical analysis. Continuous records at Wheeling extend from 1838 to 1850 and from 1861 to date with 110 years of uninterrupted data and an historical period of 132 years.

Between 1937 and 1967, the flood control reservoirs were consecutively built and flood heights have been progressively reduced. An adjustment for reservoir reduction was required to place all floods of record in a natural or modified-by-reservoir status. Consequently, computations were made for reservoir storage impoundment and release for all floods since 1935, not only to determine the effect by completed reservoirs, but also to develop a relationship between natural and modified peak flood flow magnitude. The natural and modified peaks were used to compute the frequency of

BVPS-2 UFSAR Rev. 0 2.4A-2 natural flooding and by relationship, the frequency of modified flooding.

These computations also showed how effective the reservoir system would have been on the March 1936 flood which was the highest of record. It attained an el 703 feet 1 inch at mile 35 with a peak flow of 510,000 cfs.

This flood resulted from average runoff equal to 3.0 inches of precipitation from the whole basin. Maximum precipitation

intensity occurred over the Conemaugh River basin in the contiguous areas now predominately controlled by reservoirs. The Conemaugh River is especially well situated near the center

of the tributary area above Shippingport so that it was formerly a prime contributor to a great many of the district floods. Because the controlled areas were a source of much of the March

1936 flood runoff, the reduction they could have exerted was above average. The maximum computed reduced flood therefore was not the 1936 flood but that of December 1942. This maximum reduced flood flow at mile 35.0 would be 390,000 cfs having a corresponding el 692 feet 9 inches.

Hydraulic Characteristics

Analysis of the 1936 and subsequent floods throughout the basin, stream flow measurements, backwater studies, and detailed topographic maps of the navigable portions of the Allegheny, Monongahela, and Ohio Rivers have provided unit graph and flood routing data for use in determination of actual flood factors and development of theoretical flood hydrographs. Unit hydrographs for 61 drainage areas comprising a separation into

significant portions of the total uncontrolled basin, and 13 unit graphs for the reservoir inflows have been developed for flood forecasting and reservoir operation. Flood wave routing coefficients for the Muskingum method have been developed for transposition of the unit graph flows downstream through the basin. Valley storage curves 30 to 40 feet above the maximum flood of record profile were determined to check routing values and flood storage volumes. The stage discharge relation curve for the Ohio River at mile 35 and other critical locations used in the flood routing procedures have been developed by projection of the curves beyond the flood of record by use of established channel roughness, measured cross sections, and slope values based on various elevations and the related valley storage between rating station reaches. The stage discharge relation for the Ohio River at mile 35.0 is shown as Plate 2.

Standard Project Flood

Although the March 1936 flood is indicated to be the maximum for a period as long as 200 years, undoubtedly higher floods can occur. The Ohio River Standard Project Flood was developed to establish a plausible event in excess of the record. It was to be used for design of riverside structures where an extremely high degree of

BVPS-2 UFSAR Rev. 0 2.4A-3 flood safety was advisable. Its storm rainfall values were those of an actual storm, over a further west location in the Ohio River Basin where rainfall intensities are greater due to closer proximity to the Gulf source of moisture. It was assumed that they could possibly have been more closely centered over this area. Total storm intensities used were as great as 10 inches over portions of the basin. All of the existing reservoirs were assumed to be in flood control operation during the storm. As in the 1936 storm, high intensities occurred over the Conemaugh Reservoir basin and this reservoir was filled by the time the flood had crested downstream. Spillway discharge from this reservoir and several others occurred on the flood recession. This flood has a computed peak flow of 630,000 cfs at Shippingport with a maximum stage at el 705 feet 0 inches.

This flow is about 60 percent greater than the maximum reduced flood and would appear to have only a one or two thousand to one

chance of occurring in any year.

Dam Stability The chance of augmentation of flood flows by dam failure superimposes an extreme improbability on remote probability.

All of the Pittsburgh District Corps of Engineers dams were designed for localized probable maximum storm runoff. They will not fail from overtopping especially from less intense rainfall of more generalized widespread storms such as the Standard Project Flood.

Military personnel also consider it highly improbable to critically breach these dams by sabotage, using conventional means or weapons, because of their mass. The most likely cause of their failure would be from a catastrophic event such as an atomic explosion or an earthquake in the immediate area coincidental with full or near full impoundment. The widespread destruction resulting from an atomic blast, or more significantly from an atomic attack of which it could be a part, could minimize the more local effects that might be caused by dam failure. The Pittsburgh District reservoirs whose failure would most likely have the greatest flooding effect at

Shippingport function solely as flood control projects and consequently are usually at minimum storage. The decreased chance of destruction of these reservoirs when full compounds

the improbability of flooding from this source.

At the World Conference of Earthquake Engineering in Chile, various charts and discussions indicated the improbability of dam failure from earthquakes in this area. Civil Engineering, October 1969, page 73, shows the seismic risk map presented at

the conference. It indicates that this basin lies within a zone-one designation where earthquake damage can be only minor.

Also presented at this conference was a paper that described an earthquake which produced horizontal cracks through a new 300-foot high concrete gravity dam at Koyna, India, in 1967. The shock was of high magnitude registering BVPS-2 UFSAR Rev. 0 2.4A-4 6.5 on the Richter scale. Breaching did not occur (Civil Engineering, March 1969, page 83).

A more local example of the relation between stability of our

gravity dams and earth shock was observed on November 19, 1969 at Bluestone Dam located in southeastern West Virginia. A tremor registered at 4.75 on the Richter scale occurred about 40 miles from the dam at 8 p.m. of this day. A thorough investigation at the dam showed no effect. Personnel on duty at the dam were not conscious of the tremor although people in nearby homes were alarmed at the vibration in these less substantial structures.

Even though breaching is believed to be improbable, especially coincidental with the peak of the Standard Project Flood, it was given consideration and a computation was made to show the

effect of failure of the critically located Conemaugh Dam. The attendant wave from this failure would have raised the peak flow at Shippingport to 1,280,000 cfs with a peak stage at el 725

feet 2 inches.

Probable Maximum Flood Despite the extreme magnitude of such theoretical flood conditions, still more critical conditions are conceivable from the Probable Maximum Rainfall. Such a rainfall represents the culmination of combined critical meteorological factors.

Meteorologists do not reasonably concur that more critical rainfall can be experienced. The flood runoff resulting from such rainfall, when compared to frequency projections developed by the accepted conventional computation methods, show this

maximum event to be in excess of even extreme probability projections, indicating a frequency of once in a geologic age.

Although a probable maximum storm had not been previously developed for the tributary area upstream of Shippingport, a study of this type had been made for the Susquehanna River basin which is adjacent to this area and located to the east. This probable maximum precipitation was presented in Weather Bureau Hydrometeorological Report 40. Consultation with the Office of Chief of Engineers and the Weather Bureau Hydrometeorological Section confirmed the assumption that data in this report could be reasonably applied to the Pittsburgh area. This report presented a storm pattern in the form of isohyetal lines (contours of equal precipitation) developed for 24,100 square miles of drainage area in the Susquehanna basin above

Harrisburg, Pennsylvania. This area is of about the same size as that above Shippingport.

Orientation of the storm pattern over the Pittsburgh District was performed by transposing it 2.5 degrees longitude west and 0.8 degrees latitude south. This was believed to be not only a logical transposition but also one conducive to the peak runoff maximization. The isohyetal storm pattern is shown on Plate 1 with the values of intensity and time

distribution of the isohyets

BVPS-2 UFSAR Rev. 0 2.4A-5 tabulated on Plate 3. Both the pattern and table were obtained from Report No. 40.

Individual hydrographs for each of the 61 subareas in the basin

and for the areas above the 13 reservoirs were developed from the unit graphs and the 6-hour rainfall values, applicable to the particular areas, modified by infiltration losses. These

losses have been found applicable to storms of similar characteristics and seasonal occurrence in this area.

The uncontrolled area hydrographs routed to Shippingport resulted in a combined flood hydrograph of 1,430,000 cfs.

The reservoir inflow hydrographs were developed in a similar manner with unit graphs and the oriented rainfall values. In no case were these flood flows as great as the spillway design floods which were used to assure the safety of the dam against overtopping and failure. Reservoir storage during the early storm periods was sustained long enough to permit downstream passage of the flood peak before spillway discharge could appreciably add to its magnitude. Ultimate reservoir storage heights were below structural design levels.

Reservoir outflows were subsequently routed downstream through the basin and were combined with the uncontrolled flow hydrographs to form the probable maximum flood as modified by the 13 existing reservoirs.

This flood so developed has a maximum flow magnitude of 1,500,000 cfs and would attain an el 730 feet 0 inches at Ohio river mile 35. It is almost 4 times as great as the maximum reduced flood in our 200 years of record. The hydrograph of this flood is shown as Plate 4.

The mean velocity of the peak flood flow is estimated to be 10 feet per second or about 7 miles per hour. Bank velocities at the proposed structure should not exceed 3 mph.

Duration of Inundation

These floods would not only cause the river to rise to the high peak stages which have been discussed but would subject the banks and contiguous structures to protracted durations of inundation. Plate 5 presents stage-duration curves which show the length of time that various elevations would be equalled or exceeded during the Maximum Probable, Standard Project, and maximum actual reduced floods. The short duration of additional flooding caused by breaching of Conemaugh Dam during the Standard Project Flood can be readily observed.

Results and Conclusions

1. The most critical conditions which we believe possible would result from the probable maximum flood (PMF).

BVPS-2 UFSAR Rev. 0 2.4A-6 2. The probable maximum flood would have a peak flow of 1,500,000 cfs and attain an el 730 feet O inches at mile 35 feet 0 inches.

3. Outflow from the flood control reservoirs would only contribute 70,000 cfs to the flood peak. Reservoirs would operate according to their predetermined schedules and would be in no danger of failure as this flood is not as critical to them as results from their own design criteria.

4. Maximum scouring velocities at the structure would not exceed three miles per hour.

5. Failure of any of the flood control dams at any time and particularly coincidental with peak flood flow is not

believed of practical consideration.

6. The probable maximum flow is 400 percent of the comparable maximum reduced flood in the 200-year period of record.

Frequency computations which give consideration to the overall pattern of events, place this flood as only a 100-year event. The same computations indicate the probable

maximum value to be so far beyond reasonable projection limits it might be termed as a geologic era event.

7. The Ohio River Standard Project Flood at mile 35.0 is 630,000 cfs with a maximum el of 705 feet 0 inches. This

flood has a computed frequency of about once in 1,000 to

2,000 years.

8. The Standard Project Flood augmented by breaching of the Conemaugh Dam (an event believed unlikely) is 1,280,000 cfs with an elevation of 725 feet 2 inches.

The studies have been of sufficient depth and detail to assure a degree of accuracy commensurate with the reliability of projections made.

Dear Mr. Miller:

Beaver Valley Power Station -Loss of Pool In response to your letter of 2 October 1973, we are -5ubmitting the ing information relative to the possibility of a drop in the New Cumberland normal pool level during extreme low now conditions.

Should such an event occur or be anticipated, the Pittsburgh District Emergency Center will be alerted. The Center will then be respo:wible for directly notifying the Beaver Valley Power Station, land:ings, intakes and other interested parties affected by a drawdown in the pool. It wUl also notify the public through press releases to the various news media. Dw'ing any low flow period, navigation pools such as New Cumberland would not be intentionally lowered. Locking activities coUld be continued at normal rates without any drawdown of the pool, even if the flow was at the minimum rate of SOD c.r.s. stated in your letter. The only lock or tamter gate damage reasonable to assume during a drought period would be the loss of a lock gate due to a navigation accident.

Sabotage is not considered in this evaluation.

Inclosed is a copy of a letter sent to Mr. Robert J. McAllister of Duquesne Light Con;>aDY ing the situatiom; which could cause loss of pool and the resulting measures that could be taken to correct the problem. In that letter, a flow of 4,700 c.f.s. was used for the analysis.

Loss of more than one gate was also discussed.

It was assumed that any such incident would occur during a flood and that repairs would be made within two weeks. At that time the flow would be no less than 20,000 c.f.s. with a corresponding elevation of 654 feet above mean sea level (m.s.l.) at the plant.

Dear Mr. Miller:

Beaver VaJ.ley Power Station -Loss of Pool. In response to your letter of 2 October 1973, we are -submitting the ing information relative to the possibility of a drop in the New Cumberland normal pool level during extreme low now conditions.

ShoUld such an event occur or be anticipated, the Pittsburgh District Emergency Center will be alerted. The Center will then be responsible for directly notifying the Beaver Vall.ey Power Station, landings, :intakes and other interested parties affected by a drawdown in the pool. It will also notify the public through press releases to the various news media. During any low now period, navigation pools such as New Cumberland would not be intentionally lowered. Locking activi.ties could be cant:inued at normal rates without any drawdown of the pool, even if the flow was at the minimum rate of BOO c.f.s. stated in your letter. The only lock or tainter gate damage reasonable to assume during a drought period woUld be the loss of a lock gate due to a navigation accident.

Sabotage is not considered in this evaluation.

Inclosed is a copy of a letter sent to Mr. Robert J. McAllister of Duquesne Light Coopany :ing the situations which could cause loss of pool and the resulting measures that could be taken to correct the problem. In that letter, a now of 4,700 c.t.s. was used for the analysis.

Loss of more than one gate wa.:s also discussed.

It was assumed that any such incident would occur during a flood and that repairs would be made within two weeks. At that time the now would be no less than 20,000 c.t.s. with a corresponding elevation of 654 teet above mean sea level (m.s.l.) at the plant.

BVPS-2 UFSAR Rev. 15 2.4B-4 OHPED-() Mr. Richard C. Miller 1 November 1973 Our present analysis considers an extreme drought with a flow of 800 c.f.se Slnce the only damage that coul.d reasonably be expected to occur with this flow is the of a gate, the bulkheads coul.d be installed witlUn four hours and there would be no fUrther loss of pool. During these four hours of open flow, the pool woul.d drop 1.S feet to elevation 662.7 feet m.s.l. Computations were made to evaluate the loss of a tainter gate or lock gate without placing the bulkhead:s, although we do not cOll:lider this a reasonable possibilitYe Since you a....-e l..1'lterested

in the rate of fall to jOur critical elevation of 948.0 mes.l., we have included flate 1 show:i.ng the pool recession for these conditions.
