2.2.1.3 Millstone Point Fauna Faunistic studies of Millstone Point were conducted concurrently with floral-investigations in 1973-74 (Figure 2.2-1). The objectives of the program were:

.1. - To identify migrant and/or resident population of mammals, ll birds, reptiles and amphibians, and terrestrial

} invertebrates in the vicinity of the site

2. To determine the general distribution and interrelationships -

of existing wildlife populations t

3. To assess the utilization of existing wildlife habitats by i birds and mammal populations

4. To determine existing effects cf natural arid man-induced factors on communities in the area i Results of the-faunal investigations are preanted.in detail in the Summary Report, 1974 (NUSCo. 1974). Thus, only < brief summary of the data is presented herein.

2.2.1.3.1 Mammals Eight small mammal species totaling 454 specimens were captured from

-May to October 1973 (Table 2.2-2). The white-footed mouse

, .(Peromyscus leucopus) was the .most abundant and widespread small

( mammal collected during the sampling period. This species was l collected in each community sampled and accounted for 61.0 percent of

the total mammal catch (NUSCo. 1974; Industrial Bio-Test l Laboratories, Inc. 1974b). Meadow voles (Microtus pennsylvanicus)

L

.were most abundant in October and constituted. 29.7 percent of the total mammal catch. Less abundant species included the shortail shrew (Blarina brevicauda),-meadow jumping mouse _

_Zapus

( hudsonius),

Norway rat (Rattus. norvegicus)', masked shrew (Sorex cinereus),

i eastern chipmunk (Tamias striatus) and pine vole (Pitymys pinetorum).

L ' Data on sex,- weight and selected body measurements of individual l

species were.also collected (NUSCo. 1974).

Habitat Utilization, defined -as the proportion of animals ' captured l- -within each habitat type, was highest in the beach community and

' lowest in the xeric hardwood forest (Community 6). The, relative

. abundance of small mammals increased significantly (p <0.05) from May to July. Increases were greatest in the beach and managed recreation area,- beach community, and .the transmission line corridor (NUSCo.-1974).

Observations and/or sign of seven larger mammals were recorded during j the 1973-74 field survey -(Table 2.2-3). Cottontail rabbits-l (Sylvilagus spp.), eastern gray squirrels (Sciurus carolinensis) and L , woodchucks (Marmota monax) were common. Visual observations or signs L of cottontail rabbits were recorded in all habitats, with the s exception of the coastal marsh (Community 4). Cottontails were the

MNPS-3 EROLS most frequently observed larger mammal, accounting for 47 percent of the sightings (NUSCo. 1974; Industrial Bio-Test Laboratories, Inc. 1974b). The eastern gray squirrel was recorded in three communities but observations were largely restricted to the mesic hardwood stand (Community 2) and xeric hardwood stand (Community 6).

Woodchucks were also abundant onsite, occurring in the riparian hardwood stand (Community 3), the transmission corridor (Community 5), the abandoned nursery (Community 7) and the beach (Community 9).

Other species recorded from the Millstone Point site included raccoon (Procyon lotor), starnose mole (Condylura ciristata), muskrat (ondatra zibethicus) and white-tailed deer (Odocoileus virginianus).

Only one white-tailed deer was recorded from the site; however, suitable habit for deer is present, particularly along the forest borders.

2.2.1.3.2 Birds Observations of 3,692 birds comprising 106 species were recorded along nine transect routes during the 1973-74 survey (NUSCo. 1974; Industrial Bio-Test Laboratories, Inc. 1974b). Resident status of these species included 39 permanent residents, 42 summer residents, 10 winter residents and 11 migrants (Table 2.2-4). During the spring and fall migration periods, 63 and 55 species, respectively, were sighted. Sixty-two species were recorded during the summer survey and 35 were observed during the winter census.

Predominant birds sighted during the May migration period included -

red-winged blackbirds (Agelaius phoeniceus), common grackles (Quiscalus quiscula), barn swallows (Hirundo rustica) and starlings (Strunus vulgaris). Common nesting species observed during July included black ducks (Anas rubripes), blue jay (Cyanocitta cristata),

American robin (Turdus migratorius), and song sparrow (Melospiza melodia).

In October, double-crested cormorants (Phalacrocorax auritus), Canada geese (Branta canadenses), herring gulls (Larus argentatus),

starlings and American goldfinches (Spinus tristis) were most frequently sighted. Red-breasted merganser (Mergus serrator),

herring gulls, ring-billed gulls (Larus delawarensis), and song sparrows were most prevalent durring the January census.

Raptorial birds observed in the Millstone Point area included ,

Cooper's hawk (Accipiter cooperii), red-tailed hawk (Beuteo jamaicensis), broadwinged hawk (B. platypterus), osprey (Pandion haliaetus), and American kestrel (Falco sparverius).

The osprey is the most conspicuous raptor on Millstone Point.

NUSCo., in cooperation with the Connecticut Department of Environmental Protection, has maintained nesting platforms onsite 8 since 1969. As of the end of 1984, five artificial nesting platforms had been established. Young osprey were successfully produced every year during 1974-1980 and in 1981 osprey in two nests successfully Amendment 8 2.2-8 December 1984 Eju

[

MNPS-3 EROLS produced' a total of four fledglings. In the period of 1969-1980, 8 osprey produced 32 offspring using the nests onsite (NUSCo 1981a).

The. quarry nest was investigated in 1976, 1977, and 1978 by adult ospreys but remained unoccupied. The highly successful wildlife area l 8 nest, however, continues to assist in sustaining the Osprey population of Connecticut.

During the 1977 reconnaissance of the Millstone Point site, bird observations were made in the vicinity of the wildlife management pond. . Most noteworthy was the presence of great blue herons -(Ardea herodius), black-crowned night herons (Nycticorax nycticorax), two

--adult whistling swans (Olor columbianus) and five juveniles, belted kingfisher (Megaceryle alceyon), and pied-billed grebe (Podilymbus podiceps). A number of ducks and a.large number of passerine species were also noted, suggesting that the wildlife management area a continues to be ' a highly productive area with respect to avian species.

2.2.1.3.3 Reptiles and Amphibians During the 1973-74 field survey, five species of amphibians and one species of reptile were observed in the Millstone Point area (Table 2.2-6).

One northern two-lined salamander-(Eurycea bislineata) was captured m at the edge' of the stream in the riparian hardwood stand (Community 3). One American toad (Bufo americanus) was recorded from

~

the xeric hardwood stand (Community 6). Green frogs-(Rana clamitans) were the most abundant amphibian onsite, observed most frequently in the riparian hardwocds stand, coastal marsh (Community 4), and the abandoned nursery -(Community 7). Leopard frogs (Rana pipiens) were recorded from the transmission line corridor (Community 5) and the abandoned nursery, while wood frogs (Rana sylvatica) were observed in the old field (Community 1) and the two hardwood stands (Communities 2 and 6).

With respect ~ to -reptiles, the eastern garter snake (Thamnophis sirtalis) was recorded' from the riparian hardwood stand and transmission line corridor. This species occurs in a wide. variety of habitats. -

r. Terrestrial Invertebrates Two hundred thirty-seven specimens representing 2 classes, 11 orders, and 40 families of terrestrial invertcbrates were collected from the old field (Community.1)- and riparian hardwood stand (Community 3) during the 1973-74 field survey. Plant bugs, dance flies, midges and spiders -were the species most commonly collected. The relative abundance.and diversity of invertebrates were greater in the old field than in the riparian hardwood stand.

' Amendment 8 2.2-9 December 1984

MNPS-3 EROLS 2.2.1.4 Environmental Stresses During the 1972-1974 terrestrial field studies, ground surveys were made to determine the major environmental stresses (both natural and man-induced) on native plant communities of the Millstone Point site.

The most common stresses were caused by lumbering, insect infestations, flooding, fires, hurricanes, gales, and by the conversion of native communities to farm land, residences, commercial and industrial developments, and transportation networks. (NUSCo.

1974). Natural stresses caused by several topographic, edaphic, and physical factors associated with the coastal environment were also present (NUSCo. 1974).

The 1977 reconnaissance of the site revealed very little change in community structure since the 1973-1974 survey. No evidence of major natural environmental stresses was observed. However, man-induced perturbations, associated with the construction of Millstone 3, were noted which may have affected the quality of the terrestrial communities adjacent to the construction site. Inadequate sediment barriers, in conjunction with -heavy precipitation in October, resulted in a small deposition of silt in the marsh west of the construction site and in the mixed hardwood stand west of the batch plant. Several small areas of unchecked erosion due to heavy rainfall and imprcper stabilization of sicpes vcre also noted on site. In addition, storage of fill material in the storage area west of the craft parking lot had led to a depositing of fill in the marsh and woods immediately west of the storage bins.

Subsequent to an Environmental Site Audit, these construction-related problems were rectified. New sediment barriers were installed and slopes were stabilized by seeding (section 4.1.4).

2.2.1.5 Endangered Species No rare or endangered species of flora or fauna listed by the U.S.

Department of Interior, Fish, and Wildlife Service as endangered (U.S. Department of Interior 1979) were observed during the field investigations or are likely to permanently inhabit the Millstone Point site. With respect to mammals, the Indiana bat (Myotis sodalis) is the only potentially occurring endangered species. The geographic range of this bat extends into connecticut (Burt and Grossenheider 1964; Hall and Kelson 1959). It is known that the Indiana bat requires roosting caves in winter; however, little is known about its habitat requeaements in the summer. Hollow trees and man-made structures are thought to provide suitable summer habitat (Burt and Grossenheider 1964). Thus, it is conceivable that if the Indiana bat is present in Connecticut during summer months, it may find a suitable habitat at Millstone Point. However, the lack of limestone caves on the Millstone site suggests that favorable winter roosting habitat is not available.

With respect to avian species, two species, the bald eagle (Haliaeetus leucocephalus) and Artic peregrine falcon (Falco peregrinus tundrius) may be found in Connecticut. The bald eagle may 2.2-10 .

' 3.4' 1 ' Circulating Water System The Millstone 3 circulating water system (Figure 3.4-1) pumps salt y" water from Niantic Bay through a single-pass, triple shell condenser

^ at ' a rate Jof. approximately 57' cubic meters /sec (2,000 cfs) to condense the' steam rejected by the main turbine. The expected temperature . range of inlet water is between 0.6*C (33*F) and 24'C

'~

(75*F). .During its passage through the condenser, the circulating water > is heated approximately ~ 9.4*C (17'F) above its inlet.

temperature. The heated circulating water is then discharged into the quarry, located on the southeast extremity of Millstone Point,

- where it is combined with the_ discharge of Millstone 1 and 2. The total combined flow-from the circulating water systems of all three Millstone units is approximately 118 cubic meters /sec (4,160 cfs),

t with. a maximum temperature rise at full load of about 11.7'c (21*F).

Figure 3.4-2 shows the overall plan for Millstone 3.

4 The circulating and service water pumphouse (Figure 3.4-3) is divided into six bays which supply water to six circulating water pumps, four service; water -pumps, and two screenwash pumps. Flow to each bay leaves Niantic Bay-and passes through a trash rack and a traveling *

- water screen in each bay. The average velocity within the pumphouse

bays during normal operation at low water elevation is about 0.24' meters /sec (0.8 fps).

% The trash racks are 4.9 meters (16 feet - 1 inch) wide and consist of-1.3-cm (1/2-inch) thick by 8.9 cm (3-1/2 inch) deep vertical steel bars installed 6.4 cm (2-1/2 inches) apart on centers at a slope of 5 on 1. Two traversing trash rakes remove debris from the six trash-racks- by means of' motor operated cable hoists mounted on a steel superstructure (located at elevation 4.4 meters [14.5 feet] and deposit'the debris into trash carts for removal.

The traveling water screens are located upstream of the circulating water pumps and consist- of an : endless band of screening panels 4.3 meters 1(14 feet) wide by,0.61 meters (2 feet) high constructed of-

-No. 17 W&M gage 4.76 mm (3/16-inch) mesh copper cloth, which has a

.60-percent clear opening. Each bay has an overall 48-percent clear opening based on 100-percent clean screen. The screens are automatically operated- according to the differential water. level across each screen. Screen wash water is discharged from the screen wash ~~ headers through high pressure spray nozzles at 6 kg/sq cm l8

'(85 psi) to clean debris off the screens into an upper trash trough and through- gentle wash spray nozzles at.0.7 kg/sq cm (10 psi) to flush organisms from the fish trays on' the acreens into .a fish trough. The debris is removed from the trash trough by a motorized conveyor' system to a trash ~~ container for removal. The fish are carried from the fish trough to a fish sluiceway running from the pumphouse back to Niantic Bay.

Th'e circulating water flows from the six circulating water pumps to

' the condenser through six independent 183-meter (600-foot) long lAmenchnent 8 3.4-1 December 1984

MNPS-3 EROLS 213-cm (84-inch) diameter pipelines. The pipe is copper nickel clad steel inside the pumphouse, reinforced concrete outside the pumphouse, and concrete encased fiberglass inside the turbine building. The 213-cm (84-inch) diameter pipes transition to 244-cm (96-inch) diameter pipes just upstream of the condenser to improve flow characteristics inside the inlet water boxes. The condenser is a single-pass, 46,758 square meter (503,300 square foot), triple shell condenser with 28.6-mm (1-1/8 inch) diameter titanium tubes.

Each condenser shell is served by two circulating water pumps. The circulating water discharges from the condenser outlet water boxes through six independent 4.3- by 4.3-meter (50-foot) long 213-cm (84-inch) diameter pipelines. The pipes are copper nickel clad steel followed by concrete encased fiberglass which combine into one 4.3 by 4.3 meter (14 by 14 foot) reinforced concrete tunnel. An additional flow of approximately 114 cubic meters / min (30,000 gpm) from the service water system enters the tunnel immediately downstream of the condenser. This 503-meter (1,650-foot) long tunnel runs to a seal pit structure at the quarry where the circulating water passes over a

' weir, into the quarry, and finally through a channel into Long Island Sound. The water discharges from the seal pit structure at an average velocity of about 0.76 meters /sec (2.5 fps).

A 152 cm (60-inch) diameter recirculating tempering line is provided from the upstream end of the discharge tunnel to the circulating and service water pumphouse to prevent ice formation around the intake during the winter.

The circulating water pumps are arranged in pairs such that the three h pairs of pumps serve the three condenser shells, as shown on Figure 3.4-1. Each pair of pumps is interconnected at the circulating and service water pumphouse by lateral passageways and at the condenser inlet and outlet water boxes by cross connecting 168-cm (66-inch) diameter motor operated valves. This arrangement provides for recirculation of the discharged water for back flushing of the condenser, and for biofouling control of the intake lines, and the pumphouse. An Amertap tube cleaning system is provided for each condenser flow path to maintain a high level of tube cleanliness.

This eliminates the need for a chlorine injection system in the circulating water system. However, in the event that thermal backwashing or tube cleaning proves unsuccessful, provisions for a chlorine injection system have been incorporated into the design of the circulating water system. The existing service water chlorination system (Section 3.4.2) has been designed with the capability to retrofit a chlorination system to provide sequential, intermittent chlorination downstream of the traveling water screens in each circulating water intake bay. This system would back up the 2 Amertap system to provide condenser slime control. Should a more extensive, continuous chlorination program be required to control QE291.8 hard shell fouling in the intake structure, additional chlorination equipment would be necessary. Chlorination frequency, duration, and concentration are indeterminate at this time, since this option is not expected to be added to the circulating water system. However, any chlorination program would be within the EPA Effluent Limitation Guidelines in 40 CFR 423.

i 3.4.2 Service Water System LThe service water system provides cooling water for heat removal from the reactor plant auxiliary systems during all. modes of operation and

-from. the turbine plant auxiliary systems during_ normal operation.

The service water-also supplies lubrication water for the service and circulating water pump bearings. The service water system is shown schematically on Figure;3.4-4.

The -service water system consists of two redundant flow paths. Each flow path is composed of two service water pumps and two service g- water strainers along with the necessary piping, heat exchangers, and valves. . The service water pumps and strainers are located in the circulating and service water pumphouse (Figure 3.4-3) . Each service water pump supplies-50 percent of the required flow, and is rated at 57 cubic meters / min (15,000 gpm), 36.6 meters (120-feet) total dynamic head (TDH). Each service water pump is located in a separate pump bay between the traveling water screen and the circulating water pump. .Each pair of pumps is isolated in a flood protected, seismically designed cubicle inside the pumphouse. The service water.

s strainers are self-cleaning.and have a maximum particle size of 1.59 mm (0.0625 inch). Debris removed from the strainers is discharged back to Niantic Bay.

4 The ' service water system draws cooling water from Niantic Bay, and after passing it through various heat exchangers, discharges it - into Long. Island Sound via the circulating water system discharge tunnel.

Service water!-flow- and heat load requirements under all operating

- conditions are listed.'in' Table 3.4-1. Under all operating conditions, 'except for -the minimum Jengineered safety features required during a design basis accident (DBA), coincident with a loss lF of power (LOP), one service water pump on each of the two trains is g operating. Under normal operation, the relatively small flow and temperature rise of the se rvice water system does not cause any

-appreciable increase in the temperature of the circulating water at the quarry discharge. Under accident operating conditions (DBA coincident with LOP),. the temperature increase in the service ' water

^

• This section describes the nonradioactive liquid waste discharges from Millstone 3. The chemical additions to water used for the station operation are presented in Table 3.6-1.

3.6.1 Makeup Water Treatment System 3.6.1.1. Makeup Demineralizer Regeneration The makeup demineralizer system for Millstone 3 consists of two trains, each having a capacity of 469 liters / min (124 gpm). Each train consists of an activated carbon filter, a cation demineralizer, an anion demineralizer, and a mixed bed demineralizer, arranged in series. An ultrafiltration system is provided upstream of the demineralizers to remove suspended solids and large organic molecules

-- to prevent fouling of the demineralizer resins. Under average operating conditions, the demineralizers require chemical regeneration of- the resins of one of the two trains approximately every 3 days. The total regeneration waste volume per train is 7 approximately 190,000 liters (50,000 kallons).

J

-The main constituent of the regeneration wastes is sodium sulfate, resulting from the use of sulfuric acid and sodium hydroxide as the regenerating chemicals. Regeneration of one train of the cation and anion demineralizers requires the use of approximately 189 liters (50 gallons) of acid (66*Be) and 363 liters (96 gallons) of caustic O\ (50-percent solution), respectively. Regeneration of the mixed' bed demineralizer resins requires approximately 30 liters.(8 gallons) of acid and 45 liters (12 gallons) of caustic. The combined regeneration vastes contain approximately 3,230 ag/1 of sulfate and 1,460 mg/l of sodium (Table 3.6-2). Regeneration wastes from the cation, anion,. and mixed bed demineralizers are neutralized to a pH between 6.0 and 9.0 and discharged to the circulating water system as discussed in Section 5.3.

The waste neutralization system is shown schematically on Figure 3.6-1. The system is a batch neutralization process in.-which wastes are recirculated within the- waste regenerant neutralizing sump. Acid and caustic are added to the' sump, as required, to adjust the pH of the wastes to within a range of 6.0 to 9.0. When the pH is within this range, the sump contents are discharged to 'the circulating water discharge tunnel.

3.6.1.2 ' Condensate Polisher Regeneration Condensate . polishing demineralizers maintain the condensate and feedwater system water quality. A total of eight mixed bed demineralizers (seven operating and one spare), each with a capacity of .10,690 liters / min (2,825 gpm), are provided to demineralize condensate flow. Each polisher requires periodic regeneration of the resins'with sulfuric acid and sodium hydroxide. It is expected that under. average operating conditions, one polisher'per day will be

- regenerated. The total regeneration waste volume per polisher is Amendment 7 3.6-1 April 1984

MNPS-3 EROLS approximately 121,000 liters (32,000 gallons), of which 87,100 liters (23,000 gallons) are discharged to the chemical waste sump to be neutralized and monitored for radioactivity. The remaining 34,100 liters (9,000 gallons) are recycled to the water recovery tank.

The condensate polishing regeneration wastes are discharged after neutralization to a pH between 6.0 and 9.0 to the circulating water discharge tunnel. The main constituent of these wastes is sodium sulfate, resulting from the use of acid and caustic for regeneration.

It is estimated that the concentrations of sulfate and sodium in the wastes discharged to the circulating water are 3,930 mg/l and 1,770 mg/1, respectively.

If the condensate polishing regeneration wastes are determined to be radioactive, they will be treated as discussed in Section 3.5.2.

The waste neutralization system for condensate polisher regeneration wastes is similar to that described for the makeup demineralizer except that two sumps are supplied and are equipped with a common radiation monitor to detect potentially radioactive waste.

3.6.2 Biocide Wastes The circulating water system (Section 3.4) is a once-through cooling system which draws water from the Niantic Bay area of Long Island Sound at a rate of approximately 56.6 cubic meters /sec (2,000 cfs).

This water passes through the main condenser, which condenses steam exhausted from the turbine generator. Physical and chemical characteristics of Long Island Sound water are discussed in Section 2.4 and Section 5.3.

The six circulating water pumps are arranged in pairs such that the three pairs of pumps serve the three condenser shells (Section 3.4).

Interconnection of each pair of pumps provides recirculation of the discharged water for backflushing of the condenser and for biofouling control of the intake lines and the pumphouse. A mechanical condenser tube cleaning system (Amertap), employing sponge rubber balls, provides for control of biofouling in the condenser.  !

Chlorination of the circulating water for biofouling control is not ,

anticipated. l The service water system is a once-through cooling system which draws J water from Long Island Sound at a rate of 1.87 cubic meter /sec '

(66 cfs). This water cools the components and heat exchangers in the engineered safety features building, control building, auxiliary building, turbine building, and other unit structures. After passing through these heat exchangers, the service water is discharged to the . l circulating water discharge tunnel, where it is mixed with the circulating water and discharged to the quarry located on the southeast extremity of Hillstone Point.

A gaseous chlorine solution is injected into the service water system )

8 to control biofouling. The service water is chlorinated continuously for the control of mussels. A 2-year study of Millstone Units 1 and Amendment 8 3.6-2 December 1984

HNPS-3 EROLS O 2 is ongoing to determine the minimum amount of chlorine required to 8 prevent macrofouling. Chlorination is controlled by grab sample monitoring such that the concentration of free available chlorine at the point where the mixture of service water and circulating water is 291.9 discharged to the quarry is maintained at a maximum of or less than 0.25 ppm. After mixing with the quarry water, the concentration of total residual chlorine is reduced to a concentration below l8 detectable limits (i.e., less than 0.05 ppm). In addition, the chlorine demand of the circulating water will further reduce the free residual chlorine concentration below that which would occur through dilution alone. It is estimated that approximately 26,000 kg/yr 8 (57,000 lb/yr) of chlorine (as Cl )a will be used for service water chlorination.

3.6.3 Floor and Equipment Drainage Radioactive and potentially radioactive floor drainage is conveyed to the liquid radwaste treatment system (Section 3.5). Nonradioactive floor and equipment drainage, resulting from pump seal leaks, pump seal and bearing water, floor washing, etc, is discharged to the yard storm sewer. Oil contaminated floor drainage is conveyed to oil / water separators before discharge. The oil removed is collected in drums and hauled offsite for recycle or disposal. The amount of floor drainage discharged to the yard storm sewer on a daily basis is variable. There are three oil / water separators, each having a design capacity of 379 liters / min (100 gpm), for the Millstone 3 plant areas. Oil and grease concentrations in the separate effluent are limited to 10 mg/1, average and 20 mg/1, maximum.

3.6.4 other Liquid Wastes 3.6.4.1 Steam Generator Blowdown The design of the steam generator blowdown system provides a means of controlling the suspended solids concentration and the chemical composition of the steam generator shell water. The system is capable of blowing down water from each of the four steam generators at various blowdown rates up to a maximum of 341 liters / min (90 gpm) per steam generator. Blowdown from each steam generator is conveyed to the blowdown flash tank in which pressure is maintained at a point slightly above the normal operating pressure of the fourth point feedwater heater shells. Characteristics of steam generator blowdown are presented in Table 3.6-3.

Steam from the flash tank is conveyed to the feedwater heaters. The remaining liquid in the flash tank drains by pressure differential to the condensate side of the condenser. Contaminants are removed from

.the liquid in the condensate polishing demineralizers, which are located downstream of the condenser. By using the above system, steam generator blowdown will not be discharged to the environment under normal plant operating conditions. During an extended plant outage, the steam generator shells may be drained through the blowdown lines to the condensate polishing system vaste Amendment 8 3.6-3 December 1984

neutralization sump or, if required, to the low level waste drain j tanks in the liquid radwaste system (Section 3.5).

3.6.4.2 Low Level Waste Drain Tank Approximately 473,000 liters (125,000 gallons) of distillate are discharged, on an annual basis, to the circulating water discharge tunnel from the boron evaporator for tritium control. This waste is initially stored in the 15,000-liter (4,000-gallon) low level waste drain tank prior to discharge to the circulating water. The waste is released from the low level waste drain tank at a rate of 189 liters ,

(50 gpm) on an average of once every 18 days, l The bulk of the discharges occurs during de 6 weeks prior to )

refueling. Distillate from the boron evaporator is treated using the boron demineralizers, boron demineralizer filter, and the effluent filters. Boron is the only constituent in this .aste.

Potentially radioactive floor and equipment drainage is collected and fed into the low level waste drain tanks via the aerated drains system and discharged to the circulating water at a rate of 189 liters (50 gpm) for approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> on an average of once every month. Contaminated shower drainage is also collected in the low level waste drain tanks and demineralized and discharged to the circulating water at 189 liters (50 gpm) in a rr.anner similar to the boron recovery evaporator distillate. In both cases, the main contaminants are detergents from showers and floor washes.

Approximately 1,290 liters (340 gallons) of leakage from the reactor coolant system are assumed to occur on an annual basis. This leakage is diluted by washing down for decontamination purposes and further diluted in the low level waste drain tanks by other equipment and floor drainage. Small quantities, less than 1 ppm of lithium hydroxide used for pH control, could be released from this source.

3.6.4.3 Waste Test Tank Discharges The high level radioactive liquid waste treatment system is described in Section 3.5. Distillate from the waste evaporators is conveyed to the 5aste test tank and discharged after demineralization to either primary grade water storage or to the circulating water discharge tunnel, depending on the plant water balance.

The waste evaporators are designed assuming that all distillate will be discharged to the circulating water. Whenever steam generator leaks exceeding the maximum allowable leak occur, the steam generator blowdtwn is processed by the waste evaporator.

The f:)llowing are the maximum amounts of liquids handled by the waste evaporators annually:

A' raw - sewage analysis performed on a sample from the plant is presented in Table 3.7-2.

[ The ~ force main and pumping station are designed in compliance with the Connecticut Department of Environmental Protection standards and 8 the state of Connecticut Public Health Code.

-Based on a hydraulic loading of 25 gallons per capita per day and a three-plant population of 1,000 during normal plant operations, the estimated average daily sewage flow is 26,000 gallons per day. ,

The pumping station and force main have periodic preventive

, maintenance inspections and both have alarms signalled to a 24-hour manned station should a pumping problem occur.

3.7.2 Laboratory Wastes small quantities of laboratory wastes are discharged periodically to

( 4 the liquid waste tanks. These wastes consist primarily of reactor and turbine plant samples, as well as small quantities of chemicals required for analytical testing of various plant systems. The wastes, are treated as described in. section~3.5 and are conveyed to'the liquid waste system prior to discharge .to the circulating water.

These wastes are directed to the auxiliary building contaminated waste sump and pumped to either.the low or to the high level waste drain tanks.

f 3.7.3. Auxiliary Boilers Two oil-fired auxiliary boilers will provide the Millstone 3 site with steam for space heating when tWe nuclear unit is not operating. .

This time period is the estimated annual operating period for the auxiliary boilers. Both boilers will be operated simultaneously at 100-percent capacity, in order to provide sufficient steam to the site. Each boilet has a maximum firing rate of 78.3 x 108 Btu /hr.

No. 4 fuel oil will be supplied from two 91-cubic mette (24,000-gallon) tanks. Boiler and fuel parameters are listed in Table 3.7-3.

Emissions of particulates, sulfur dioxide (SO 2), nitrogen dioxide (NO3 ), carbon monoxide (CO), and total hydrocarbons from the combined boiler system were calculated from boiler and fuel parameters and from EPA emission factors (EPA 1977). Results for all pollutants were compared to applicable Connecticut standards (Table 3.7-4), and no violations were found (Connecticut Dept. of Environmental Protection 1978). Though the boilers are below the cutoff size requiring compliance with federal standards, boiler emissions do not exceed said requirements (EPA 1971).

3.7.4 Diesel Generators Two oil-fired diesel generators will provide emergency electricity when inplant outages occur. Each generator is capable of supplying 5,335 kWe. The generators will operate on No. 2 diesel fuel oil supplied from two 121-cubic meter (32,000-gallon) storage tanks and two 550-gallon day tanks. Generator and fuel parameters are listed in Table 3.7-5. Under testing conditions the diesels will not be operated simultaneously.

HNPS-3 EROLS f3 5.3 EFFECTS OF CHEMICAL AND BIOCIDE WASTE DISCHARGES 5.3.1 Water Quality Standards and Effluent Limitations -

Water quality standards and classifications for the State of Connecticut were adopted by the State Department of Environmental Protection (DEP) on September 20, 1977. According to these standards, the waters in the vicinity of the Hillstone Nuclear Power Station are classified as Class SB, "... suitable for bathing, other recreational purposes, industrial cooling, and shellfish harvesting for human consumption after depuration; excellent fish and wildlife habitat good aesthetic value."

Water quality standards for Class SB waters are presented in Table 5.3-1.

Effluent limitations for Hillstone 1, 2, and 3 are contained in National Pollutant Discharge Elimination System (NPDES) Permit No. CT0003263 (State of Connecticut DEP Order No. 1505 Modified). A summary of the limitations contained in the permit relating to discharges from Hillstone 3 are listed in Table 5.3-2.

5.3.2 Impact of Liquid Waste Discharge The major discharge associated with operation of the plant is approximately 59.4 cubic meters /sec (2,096 cfs or 942,000 gpm) of water used for cooling the main steam condensers and various heat exchangers within the plant. This water is withdrawn from Niantic Bay and is 7'N discharged to Long Island Sound, via the quarry cut. The chemical

'") composition of this water is essentially unchanged from that taken in at the intake and passed through the plant. The major liquid waste discharges from the plant are chemical wastes resulting from regeneration of the makeup demisieralizers and of the condensate polishing demineralizers.

Table 5.3-3 lists average Long Island Sound water quality based on data collected during the 1974 baseline water quality study (section 2.4).

The data have been tabulated for three areas of the Sounds Niantic Bay in the vicinity of the intake structure (Station 8); Long Island Sound at the discharge from the quarry cut (Station 1); and Long Island Sound at a point between the quarry cut and Twotree Island (Station 2).

Figure 2.4-13 shows the location of these stations. Since the data in Table 5.3-3 indicate very little difference in water quality at these three locations, no attempt has been made to predict receiving water quality outside of a defined mixing zone. The impact on Long Island Sound chemical water quality resulting from the discharge of once-through cooling water will be minimal. The impact of the vaste heat in this discharge is discussed in Section 5.1.3.

As discussed in Section 3.6, an average of approximately 443,000 liters 8 (117,000 gallons) per week of regeneration wastes from the makeup demineralizer system will be discharged, after neutralization (to pH 6.0 to 9.0), to the circulating water discharge tunnel. The principal constituents of this waste are sodium and sulfate at concentrations of 1,460 mg/l and 3,230 mg/1, respectively. The concentration of sodium in

( 'I s

this waste is less than that of the intake water, and, therefore, there Amendment 8 5.3-1 December 1984

HNPS-3 EROLS will be no increase in concentration of sodium in the discharge to the quarry. The concentration of sulfate in the regeneration wastes is approximately 786 mg/l greater than in the circulating waters however, assuming that this waste is discharged to the circulating water tunnel 8 at 7,57 liters / min (200 gpm), the resulting increase in the circulating water discharge concentrations is less than 0.2 mg/1. The discharge impact of neutralized makeup demineralizer regeneration vastes on receiving water quality is minimal.

The discharge of regeneration wastes from the condensate polishing demineralizers to the circulating water will also have a negligible impact on water quality. Under average conditions, approximately 23,000 gallons per day of acutralized condensate polisher regeneration wastes may be discharged to circulating water. These wastes will 8l c ntain approximately 3,930 mg/l of sulfate and 1,770 mg/l of sodium (Section 3.6).

Biofouling in the main steam condenser is controlled through the use of a mechanical condenser tube cleaning system (Amertap) employing captive sponge rubber balls. The use of chlorine for biofouling control in this system is not anticipated. As described in Section 3.6, the service 8l water system is chlorinated continuously. The concentration of free available chlorine in the service water at the point where the service water and circulating water is dischar@ d to the quarry is maintained at 8 l a maximum of or less than 0.25 ppm. After mixing with the quarry water, this concentration is reduced through dilution below detectable limits for free available chlorine. The chlorine demand of the circulating and 8 quarry water reduces the chlorine concentration, such that less than 0.1 ppm total residual chlorine will be discharged to Long Island Sound.

5.3.3 Effects of Chemical and Blocide Discharges on Aquatic Biota The chemical constituents of the discharge of Hillstone 3 (Sections 5.3.1 and 5.3.2) are practically indistinguishable from ambient water at the intake (Niantic Bay). Average discharge stream concentrations are within the range of ambient Niantic Bay concentrations for all parameters sampled during water quality surveys.

Additional dilution in the discharge plume ensures no adverse chemical effects on plankton, fish, or benthos in the vicinity of Hillstone Point. -

Chlorination is not used to control biofouling in the circulating water system of Hillstone 3 (section 5.3.2). An Amertap system is employed for condenser cleaning and a thermal backwash system is used in the intake to control the growth of organisms such as mussels. Piping for chlorination of the circulating water system will be installed for H111 stone 3: however, its use is not anticipated unless the mecaanical tube cleaning system should prove ineffective in controlling fouling of the condenser tubes.

8l Continuous chlorination is used to control biofouling in the service water system. The level of free available chlorine at the point where the service water and circulating water are discharged into the quarry 8 l is maintained at a maximum of or less than 0.25 ppm. After mixing with Amendment 8 5.3-2 December 1984

MNPS-3 EROLS

'l the quarry water, concentration of free available chlorine at the quarry cut is further reduced to an essentially undetectable level. Thus, no impact to the aquatic biota of Long Island Sound is anticipated.

Synergistic effects of the thermal and chemical components of the Millstone 3 discharge are unlikely to occur at the Millstone Point site, since concentrations of the chemical effluent at the point of discharge (the quarry cut) are essentially indistinguishable from ambient levels.

In addition, dilution of the discharge occurs rapidly, such that concentrations likely to be encot.ntered by aquatic organisms in those portions of the plume with less elevated temperature are, for all intents and purposes, at ambient levels. Thus, any impact to aquatic biota results from the thermal component rather than from the chemical or biocide component of the discharge. Section 5.1.3 discusses the thermal effects of the discharge in detail.

5.3.4 condenser Tube Corrosion A study was conducted in 1979 to determine the impact of condenser tube corrosion on trace metal concentrations in Long Island Sound (Waslenchuk 1980). This study determined the concentrations of copper, l8 nickel, and zine and the impact of operation of Hillstone Units 1 and 2 on these concentrations. The Hillstone Nuclear Power Station utilizes a <

once-through cooling water system. Long Island Sound water is passed through the condensers of Millstone Units 1 and 2, which contain l8 copper / nickel condenser tubes with sacrificial zine blocks used as

( corrosion inhibitors, and then discharged to Long Island Sound.

~'

In order to determine the effect of plant operation on trace metal concentrations in Long Island Sound, samples were collected at the plant intake and plant discharge. Samples were also collected along the discharge plume axis and to either side of the plume, as well as at two locations approximately 2 kilometers to either side of Millstone Point to determine ambient far-field concentrations. Ambient concentrations of dissolved copper measured at the two far-field sampling stations averaged 1.2 ug/l at the eastern station and 1.5 ug/l at the western station. A single far-field sample contained 1.0 ug/l of nickel and 1.4 ug/l of zinc. Concentrations of dissolved copper, nickel, and zine measured at the plant intake averaged 1.2 ug/1, 2.4 ug/1, and 0.4 ug/1, respectively. Concentrations of these parameters measured at the plant outfall increased by an average of 1.1 uq/1 for all parameters.

Analyses of intake and outfall water samples were performed to determine the relative concentrations of dissol'.3d and particulate phases of the metals under study. Intake total metal and dissolved concentrations showed essentially no contribution from particulate copper, nickel, and zinc. Dissolved metal concentrations in the outfall samples increased only slightly over intake concentrations while total metal concentrations increased by 3.9 ug/1, 0.6 ug/1, and 1.2 ug/l for copper, nickel, and zinc, respectively. The majority of these increases'were in the particulate fraction and are attributed to the plant cooling system.

_ Analysis of water samples collected in the area of the discharge plume indicate that the increased metal concentrations in the plant discharge f}

Amendment 8 5.3-3 December 1984 r

MNPS-3 EROLS return to ambient levels at a rate similar to that of temperatures with the plume's return to ambient levels (see Section 5.1.3).

Although the results of this program indicated an increase in the levels of copper, nickel, and zine between intake and discharge attributable to the cooling system, the values reported were within the range of ambient concentrations observed during the 1974 baseline study and during the ongoing water quality monitoring program (see Section 2.4 and Table 5.3-3). In addition, the elevated concentrations returned to ambient levels at a rate similar to temperature along the discharge For these reasons, it is concluded that corrosion of the 8 l plume.

copper / nickel condenser tubes at Millstone Units 1 and 2 will have minimal impact on the water quality of Long Island Sound.

Millstone 3 uses titanium condenser tubes, therefore, there will be no 8 additional contribution tc the heavy metal concentrations in 1.ong Island Sound due to corrosion of the condenser tubes of this unit.
