\\_)

2.2.1 The Site and Vicinity 2.2.1.1 Land Use Within the Site Boundary The property for Unit 2 is located on a 364-ha (900-acre) site owned by Niagara Mohawk Power Corporation (NMPC) in the town of Scriba, Oswego County, NY.

The site also includes Nine Mile Point Unit 1 (Unit 1).

Approximately 21 percent of the site is classified industrial.

Other major land uses within the site boundary are woodland (44 percent),

com-munications (15 percent),

inactive agricultural lands (12 percent), and wetlands (7 percent).

The communications land use category includes electric power and telephone lines, microwave stations, and television and radio towers.

The remainder of the site is a recreation area associated with the Nine Mile Point Energy Information Center and a

small orchard.

Table 2.2-1 and Figure 2,2-1 identify the land uses within the site boundary.

2.2.1.2 Land Use. in the Site Vicinity The town of Scriba is primarily rural with large areas of farmland.

Residential and commercial developments are concentrated at major road intersections and along US Route 104, which crosses the town in an east-west direction.

O Several concentrations of residential development are 4'

located in the western area of the town, along the boundary of the city of Oswego.

Seasonal residences are located along the shoreline of Lake Ontario.

Table 2.2-1A iden-tifies the nearest residences and agricultural radiological receptors by sector.

The major industrial land use in the town of Scriba consists of Units 1 and 2, the James A.

FitzPatrick (JAF) plant, and Alcan Aluminum Corporation.

Oswego County is primarily rural.

Except for the power-generating facilities, the majority of the industrial land is concentrated around the cities of Oswego and Fulton, which are located approximately 10 km (6.2 mi) southwest and 20 km (12.4 mi) south of the site, respectively.

Land use in Oswego County is predominantly open space and agricultural.

Forest, brushland, and wetlands encompass 62 percent of the county land area.

Agricultural land en-compasses 23 percent of the county land area.

Approximately 30,000 ha (74,000 acres) are used for harvested cropland (18 Table 2.2-2 provides agricultural characteristics for Oswego County.

The number of farms in Oswego County has declined from 1974 to 1978.

To encourage farmers to keep their land i

Supplement 4 2.2-1 October 1983

Nino Mile Point Unit 2 ER-OLS in agricultural production, agricultural districts have been formed under the New Yor}. State Agricultural Districts Law of 1971.

These agricultural districts are designated areas that are eligible for certain tax incentives if the land is kept in agricultural production.

Oswego County has nine agricultural districts.

Two of these districts encompass portions of the 10-km (6.2-mi) radius from the power plant.

These two districts are Scriba, which includes Scriba and the city of Oswego, and Mexico, which includes Mexico, New Haven, and Richland'2)

Lake Ontario encompasses 19,846 ha (49,040 acres),

or 63 percent of the 10-km (6.2-mi) radius from Unit 2.

The 10-km (6.2-mi) radius is centered on the Unit 2 reactor, but the land uses identified do not include those land uses within the site boundary.

Figure 2.1-2 identifies the 10-km (6.2-mi) radius of the site vicinity.

The types and areas of land uses within the 10-km (6.2-mi) radius of the site are identified in Table 2.2-3 and Figure 2.2-2.

Although only 41 ha (101 acres) of recreational land areas exist within the 10-km (6.2-mi) radius of the

site, Oswego County has a

wide variety of recreational resources, including those associated with water recreation on Lake Ontario.

Within a 10-km (6.2-mi) radius of Unit 2, there are 11 rec-reational land areas.

The nearest facility is the Energy Information Center located adjacent to Unit 1.

The information center has educational

exhibits, nature study

trails, and a picnic area.

The nearest park to the site is Scriba Park, located 8.1 km (5.0 mi) south-southwest of the site.

The park encompasses 30 ha (74 acres) and has a picnic area, playground, and swimming facilities.

Scriba Park has a

capacity of 417 persons.

Table 2.2-4 and Figure 2.2-3 identify recreational land areas within 10 km (6.2 mi) of Unit 2.

Table 2.2-4A identifies facilities utilized by the public along Lake Ontario as well as two irrigation intakes along the lake shore.

In the site

vicinity, the principal transportation facilities are the road and railroad networks.

A spur of the Conrail Corporation provides rail service to the site.

Highway access to the site is via two county

routes, Route 1A to the southwest and Route 29 to the east.

A private east-west road crosses the site and connects with these two routes.

Route 29 intersects County Route 1 approximately 4 km (2.5 mi) south-southwest of Unit 2.

The site is accessible from Route 1 (North Road) via Routes 29, 1A, and Lake View Road.

Daily traffic volume statistics include 1971 traffic counts of 1,050 vehicles on North Road, 4 km (2.5 mi) south-southwest of the site, and Supplement 4 2.2-2 October 1983

QUESTION E291.22 V

Describe procedures for disposal of preoperational cleaning solution wastes.

RESPONSE

NMPC is presently evaluating proposed preoperational cleaning and flushing activities to determine (1) the quantities of wastewater that will

result, (2) the concentration of contaminants in these wastewaters (e.g.,

suspended solids, oil and greare, cleaning agents, etc.) and (3) appropriate alternatives for the disposal of the resulting wastewaters.

One objective of this evaluation is to explore methods of reusing cleaning and flushing solutions in order to minimize the quantity of wastewater requiring disposal.

NMPC will work closely with the New York State Department of Environmental Conservation to identify acceptable wastewater disposal procedures consistent with water quality standards.

Finalized procedures are anticipated to be available by the first quarter of 1984.

QUESTION E451.16(a) (2.7.4, NUREG-0555, 2.3)

Submit for' accident consequence assessments one complete representative year (8760 hours0.101 days <br />2.433 hours <br />0.0145 weeks <br />0.00333 months <br />) of hour-by-hour meteorological data (wind speed, wind direction, stability, and precipitation) for a ground level release.

Include data substitutions for all missing periods.

a)

Transmit _the data on magnetic tape in the recommended i

SRP 2.3.3 Appendix A format.

i b)

Include a

description of the method used to substitute i

for the missing data.

i

RESPONSE

For accident consequence assessment for a

ground-level release, one representative year (1975) of complete hour-by-hour onsite meteorological data (100-percent data recovery) for the lower-level wind, stability and precipitation has been transmitted to the NRC under separate cover (reference letter from C. V. Mangan to D. Eisenhut, dated October 18, 1983).

The 1975 data are formatted as nhown in Table 451.16-1 on magnetic tape according to the recommendations of the Standard Review Plan, Section 2.3.3, Appendix A.

.,)

To achieve 100-percent data

recovery, appropriate data substitutions were made from the other ensite tower measurements made in 1975.

The 9-m (30-ft) vane is the primary direction measurement.

When this direction was

missing, the first valid direction from among the 9-m (30-ft), 30-m (100-ft),

or 61-m (200-ft)

Aerovanes, in i

sequence, was selected to replace the missing primary direction.

When the primary 9-m (30-ft) cup wind speed was

missing, the redundant 9-m (30-ft)

Aerovane speed was i

transferred without adjustment.

Since the two upper wind speeds were also missing when both 9-m (30-ft) wind speeds were missing (only 24 hr),

persistence was conservatively employed to fill in these remaining missing hours, instead of relying on data from distant National Weather Service

stations, such as Syracuse.

Stability was determined from the temperature difference between the 61-m (200-ft) and 8-m (27-ft) tower levels according to the classification scheme in Regulatory Guide 1.23.

Persistence was again employed to replace the missing 13 hr because the 30-8 m (100-27 ft) temperature difference measurements are coincidentally missing.

Since only 1 hr of precipitation was missing, persistence from the hour before of 0 mm (0 in) was substituted.

Supplement 4 Q&R E451.16(a)-1 October 1983

Nine Mile Point Unit 2 ER-OLS The representativeness of the 1975 onsite meteorological data was shown by the similarity of the 5-yr climatology at the site based on the joint frequency distributions of wind direction (with only the 9-m (30-ft)

Aerovane direction substituted) and the temperature difference betieen the 61-m (200-ft) and 8-m (27-ft) tower levels.

This joint frequency distribution of wind direction,

speed, and stability is shown in Table 451.16-2.

A comparison of the 5-yr climatology with that of 1975 is shown in Table 451.16-3 for direction and Table 451.16-4 for stability.

The comparison of precipitation rates and amounts is obtained from FSAR Table 2B-29 for the site and compares with those measured on an annual climatological basis at Syracuse given in FSAR Table 2B-41.

Nine Mile Po2nt Unit 2 ER-OLS

[)T QUESTION E451.16(b) (2.7.4, NUREG-0555, 5.3.3.1)

Submit at least one recent representative annual cycle of meteorological data on magnetic tape in the recommended format-with at least 90%

joint data recovery for the essential cooling tower modeling input parameters (wind speed 61(m),

wind direction 61(m),

stability 61-9(m),

temperature 9(m), and dew point 9(m)).

a)

Include all meteorological parameters measured at the primary tower.

b)

If necessary, substitute missing values with local /NWS data to achieve the 90% joint data recovery.

Explain the methods used to substitute missing values.

RESPONSE

A representative annual cycle of meteorological data (1974) with at least 90 percent-joint data recovery for the

-essential cooling tower modelling input parameters was submitted to the NRC under separate cover (reference letter C.V.

Mangan to D.

Eisenhut dated October 18, 1983).

The essential cooling tower parameters are the 61-m (200-ft) wind direction and

speed, the 61-8 m (200-27 ft) delta temperature, and the 9-m (30-ft) ambient and dew point

(~')g q_

temperatures.

Dew point temperature was calculated from the ambient temperature and 9-m (30-ft) relative humidity.

These parametere, along with the other onsite tower measurements, are formatted on the magnetic tape according to the Standard Reviaw Plan Section 2.3.3 Appendix A as specified in Table 451.16-5.

To achieve over 90% joint data recovery, substitution of the key parameters with other onsite tower data was necessary.

The substitution included replacement of missing 61-m (200-ft) wind directions by the 30-m (100-ft) wind directions.

In

addition, for the instances when the 9-m (30-ft) relative humidity was missing (less than 1 percent of the year), it was replaced by the 61-m (200-ft) relative humidity.

No substitutions were made to improve data recovery for the ambient and delta temperatures.

With the aforementioned substitutions, the onsite meteorological data for 1974 has 93 percent joint data recovery.

To judge the representativeness of the 1974 data, the joint frequency distribution of wind and stability at the 61-m (200-ft) level with the aforementioned substitution is presented in Table 451.16-6.

A comparison of this one year frequency distribution with that of the five-year data base

[O')

Supplement 4 Q&R E451.16(b)-1 October 1983 m..

Nine Mile Point Unit 2 ER-OLS is presented in Table 451.16-7 for direction and Table 451.16-8 for stability.

From these two tables, one concludes that 1974 is representative of the site, although minor variations in the frequency distributions occurred as expected.

QUESTION E460.25 (ER 3.5)

G' Provide the input parameter used for the fraction of feedwater processed through the condensate demineralizers to calculate expected annual gaseous and liquid effluent releases (BWR-GALE Code) from Nine Mile

Point, Unit No. 2 (NMP-2).

For a

BWR with pumped forward feedwater heater drain design (such as NMP-2), the BWR-GALE Code executes the ratio of condensate demineralizer flow rate to steam flow rate of 0.18 for iodines and 0.01 for other nuclides.

It appears that you have used a ratio value of 1.0 (full flow condensate demineralizers) in the BWR-GALE Code while your actual designed ratio value is approximately 0.7 for which the BWR-GALE Code automatically executes 0.18 and 0.01 instead.

RESPONSE

The response to this question will be provided at the end of the fourth quarter of 1983.
