No arsenic was detected during the 1974 sampling program. However,
\\s_,1 the detection limit of the analytical methods used to measure arsenic was above the concentrations reported by previous investigators.
Molybdenum The detection limit of the analytical methods used to measure molybdenum during the 1974 baseline study was 15 pg/1. The range of molybdenum concentrations recorded is from 150 to 600 pg/l in March and 38 to 56 pg/l in September. Recorded June concentrations are as high as 1 mg/l.
No molybdenum was detected in December. A major portion of the polybdenum present in the water column appears to be associated with suspended matter. In June, higher concentrations of molybdenum were detected at the station discharge than at other locations in the area.
Titanium Concentrations of 0.0 to 17.88 pg/l of titanium in the northeast Atlantic Ocean in sea water suspended matter (Blazhis:1971),
and 1 pg/l in the open ocean (Preston et al 1972) have been reported.
The detection limit for titanium during the 1974 sampling program was 150 pg/l which is above the concentrations reported by previous authors. No titanium was detected in the water column except in December, when four stations recorded a range of 150 to 320 pg/1.
Titanium was not detected at the discharge of Millstone Power h)

v Cadmium Dehlinger et al (1973) reports cadmium concentrations in eastern Long Island Sound of 0.1 pg/1. He reports that these concentrations agree with those obtained for nearshore waters by other investigators and that large concentrations of cadmium are not associated with the acid leachable material or strong chelating substances.
In eastern Long j
Island Sound, spring of 1972, he reported a range of cadmium concentrations of 0.16 to 2.7 99/1.

Dehlinger et al (1973) reperts 0.045 to 0.078 pg/l in eastern Long Island Sound in October of 1972. No mercury was detected during the 1974 sampling program. The detection limit for the mercury analysis was 2 pg/1.
Tm Smith (1971) reports 2.25 pg/l tin in the open ocean. Difficulties in tin analysis resulted in unreliable March determinations during the 1974 study.
From June to December, tin was detected in only one sample. The detection limit for tin was 200 pg/1.
Phenol Alekserva (1972) reports 0.02 to 0.08 mg/l in the open ocean. Phenol was detectable at only four sampling stations throughout 1974.

Physical Parameters and Dissolved Gases Salinity Clapp Laboratories (NUSCo. 1973) has collected salinity data around Hillstone Point. Seasonal maxima occur from September to November, peaking at greater than 31 ppt.
Seasonal rainima usually occur between March and May, generally at 27 to 28 ppt.
Jordan Cove salinities are consistently lower than levels recorded in the rest of the Millstone Point area in the May-July period. Values in the range of 25 to 26 ppt were recorded at these times. Average salinities in the area were in the range of 28 to 30 ppt.
Lowest salinities (26 to 28 ppt) recorded by TRC during the 1974 baseline study were recorded in the March-May spring runoff period on both tidal conditions. Jordan Cove and Niantic River salinities are lower than at other stations around Millstone Point during the March-May
- period, because these water bodies are sources of freshwater input to Niantic Bay.
Salinities gradually increased after May, peaking at 31 to 32 ppt in late September, and decreasing thereafter to a concentration in December similar to that recorded the previous January. The average salinity was in the range of 28 to 30 ppt.
Salinities reported in 1980 as part of the ongoing monitoring program ranged from 24.9 ppt (Giants Neck) in May to 33.0 ppt (Twotree Island) in September.
The lowest salinities for all four sampling locations were recorded in May (27.6 ppt average of all stations).

2.5.1 Topography The site is located on a small peninsula near the mouth of the Niantic River. The most striking topographic feature in the region around the site is the north-south trending ridges and valleys. The region is drained by a number of small brooks and the Thames, Niantic, and Connecticut Rivers. The maximum relief in the site area is approximately 61 meters (200 feet).
Glacial till covers much of the bedrock surface on the hills and in smaller valleys.
Figure 2.5-1 shows the topography and surficial geology of the site vicinity. The site area slopes gently upward from Long Island Sound northward to an elevation of approximately 9 meters (30 feet). Wave action has eroded the blanket of till from the promontories of Millstone Point, exposing rock at several places. The reworked material was deposited as beach sand in the protected areas.
Much of the plant area has been graded and backfilled during the construction of the three units at Millstone Point.
2.5.2 Geology
(~'}
The site is located in a geologically complex region characterized by
(._,/
metamorphosed and folded rocks of Ordovician-Silurian age. The area has been affected by four orogenies: the Avalonian (575 million years ago [m.y.a.]), the Taconian (465-445 m.y.a.), the Acadian (400-370 m.y.a.)
and the A11eghenian (230-260 m.y.a.).
The surrounding region has also been affected by rifting ranging from Triassic to Jurassic.
Since then the region has been stable with the exception t
of epeirogenic uplif t during the Cretaceous and Tertiary times and isostatic rebound resulting from the removal of the weight of ice covering the region during Pleistocene time.
The geology of the eastern portion of Connecticut is made difficult to decipher by the complex folding and faulting of the Late Paleozoic Era.
The tectonic features of eastern Connecticut are shown on Figure 2.5-2.
As shown on this figure the site lies on the east limb of the recumbent Hunts Brook syncline which mantles the Lyme Dome, just west of the site.
Much of the rock that underlies eastern Connecticut is a series of Early Paleozoic metavolcanic and meta-sedimentary rocks and granitic gneisses (Goldsmith and Dixon 1968). The site is underlain by the Monson Gneiss of pre-Silurian age and the Westerly Granite of Pennsylvanian or younger age.
The Monson Gneiss is thinly layered with light feldspathic and dark biotitic and hornblendic layers (Goldsmith 1967).
The foliation is well developed in the site area with an average trend of H67W and dips at 45 degrees northeast.

l 0231.1 A
number of faults are prominent in Eastern Connecticut (Figure 2.5-2).
The Honey Hill - Lake Char fault system lies aporoximately 24 km (15 miles) north of the Millstone site. The east-west segment of Honey Hill dips at low angles to the north; the Lake Char section dips westward at approximately 10 degrees (Dixon and Lundgren 1968). The system is thought to have been active beginning in Middle or Late Devonian time and continued into the Permian Period (170-225 m.y.a).
The latest episode of faulting is related to the Jurassie-Triassic rifting which resulted in the formation of the Jurassic-Triassic basin and a number of other high angle normal faults throughout southern New England. These faults generally trend north-sout.t.
Juro-Triassic rifting is evident at the Millstone site. Eleven fault l 2 Q231.1 zones with numerous minor associated faults have been uncovered during excavation, and all but one of these features are normal faults trending approximately north-south. A small thrust fault was found, which was related to, or is older than, the Jurassic activity.
l 2 Q231.1 Samples of the fault gouge found in the fault zones were radiometrically age dated.
The results indicate that the last activity associated with the faulting occurred approximately 142 2 Q231.1 m.y.a.
Therefore, the faulting at the site is considered to be incapable.
During the Pleistocene epoch, all of New England was covered with ice.
The topography was not greatly altered by glaciation, but the ice scoured the land, leaving scattered deposits (Figure 2.5-1) throughout the area after advancing to and beyond the southern New England coast.
The ice began to retreat from the Connecticut coast approximately 15,000 years ago (Flint 1975).

2.7.1 Site Characteristics i
5 Millstone station, with two of its' units operating and the third t
.The under construction, is situated on the tip. of a-small. peninsula
~
. extending southward into Long Island Sound.
Small residential.
- communities, as well as Route 156, bound the site'to-the north and
~
northeast.
The residential areas are mostly year-round suburban
-communities, but many of the commercial businesses. and other land-1 uses are centered'on summer tourism and vacationing. The resulting i
seasonal effects include slight increases in population and traffic j;
volume during the summer months.
Noise-sensitive areas were ' determined through the use of United
[
States Geological Survey maps and an inspection of the site environs 1
by the survey personnel. Measurement locations were chosen in the residential communities of Jordan Cove, Pleasure Beach, Millstone Road,.and Black Point to' ensure-that a complete and accurate description of the ambient sound levels could be drawn for all areas in the vicinity of the Millstone site, and that a comparison of sound
[
levels could be made with those obtained from previous noise surveys j
at similar locations.
i In all, eight measurement locations were selected as representative of the different noise-sensitive areas surrounding the station.
Two 4
locations were chosen in each of the Jordan Cove and Pleasure Beach i
areas. These communities have an unobstructed view of the Millstone
{
site,.and plant noise is generally audible. Three locations were
{
chosen in the Black Point area and a single location in the Millstone t
Road community, where the plant was generally not audible. The eight measurement positions described in Table 2.7-1 are shown on Figures 2.7-1 and 2.7-2.
E291.5 2.7.2 Ambient-Sound Levels
!L The statistical descriptors selected to delineate the ambient sound levels include residual, equivalent, and day-night sound levels.
j Residual ~ sound levels are represented by the Lu percentile level, which is the sound level exceeded 90 percent of. the time.
This residual level represents the minimum or background sound level. The equivalent sound level (Leg) is the level of steady noise which would L
have.the same total sound energy as the fluctuating noise actually l
measured in the community.
The day-night sound level (Ldn) is similar to Leg, but has a 10-dB weighting applied to noise occurring during the night since nighttime noise is censidered more annoying j
thanl the same noise during the day.
The L is calculated by l

Dominating noise sources for the residual and equivalent sound levels were observed to be plant and wind noise, with residual sound levels ranging from 30 to 45 dBA, and equivalent sound levels of 40 to 50 dBA. A slight decrease of approximately 3 or 4 dB occurs from daytime to nighttime for both residual and equivalent sound levels. This reduction of sound level seems to stem from a decline in traffic and decreased construction activity on Millstone 3 during the nighttime hours.
A similar residential community, the Pleasure Beach area, is situated some 1,676 meters to 2,286 meters (5,500 to 7,500 feet) directly east of the plant site.
Traffic and cricket-like noise dominate all percentile levels in this area, with residual sound levels in the order of 32 to 42 dBA.
The equivalent sound levels, in the small residential community close to the shore, generally range from 35 to 50 dBA, while on the more heavily traveled street further onshore, 30 to 55 dBA.
Nighttime residual sound levels are generally 6 dBA lower than daytime levels due to a decline in human activity, decreased construction activity on Millstone 3, and an absence of cricket noise.
In the same manner, nighttime equivalent sound levels are reduced 8 to 10 dBA due to the decline in traffic and aircraft flyovers.
Plant noise was clearly audible during the nighttime, often accompanied with a no wind or a favorable westerly wind condition.
Measurement Location 3, located 1,372 meters (4,500 feet) north of the plant on Mill: tone Road, represents another residential community.
Traffic noise from Route 156 and cricket-like noise govern the sound levels in this area.
Both the residual and equivalent sound levels were approximately 40 to 50 dBA during the daytime, while nighttime residual levels generally ranged from 30 to 40 dBA, and nighttime equivalent levels from 35 to 45 dBA.
Differences between day and night residual and day and night equivalent sound levels are again attributed to the decline of human activity, most notably, the variation in traffic volume during plant workers commuting hours, and the intermittent construction activity on nearby Millstone 3.
Measurement locations on Black Point are 2,591 meters to 3,505 meters (8,500 to 11,500 feet) to the west northwest of the Millstone site.
The three measurement locations include a town park, a yacht club, and a residential street. A variety of noise sources control the ambient sound levels, including traffic, wave, wind, and cricket-like noise.
On only one occasion was the plant audible, when an east wind allowed for sound propagation in the direction of Black Point.
The daytime residual sound levels fell in a range from 30 to 45 dBA at the yacht club and residential crea and 40 to 50 dBA in the park due to the heavier traffic volume. The same effect is seen in the equivalent sound level data, with ranges of 40 to 50 dBA at the yacht club and residential area, and 45 to 65 dBA in the town park.
Differences in day to nighttime measurements reveal a slight decrease 2.7-2

3.3 STATION WATER USE 3.3.1 Water Sources Seawater withdrawn from Long Island Sound supplies the once-through circulating water system and the service water system.
Freshwater from the Town of Waterford public water system supplies the unit's domestic water system, fire protection system, and makeup water treating system.
The makeup water treating system supplies deionized water to the primary grade water, auxiliary boiler, condensate storage, and auxiliary feedwater system.
3.3.2 Water Uses A schematic diagram of station water use is shown on Figure 3.3-1.
lQE291.7 2
Table 3.3-1 shows the maximum, average, and minimum use under normal operating conditions or during temporary shutdown for the various plant water systems.
Under normal operating conditions, water use will vary because systems are dependent upon loadings and demands.
Temporary shutdown will occur when the reactor is shut down for relatively long periods, such as during maintenance and refueling.
Some of the plant systems will be operating at reduced capacities (Table 3.3-1) during a temporary shutdown.
7g (A-)
t 3.3.2.1 Cooling Systems The circulating water system for Millstone 3 will draw water from the Niantic Bay area of Long Island Sound through the circulating and service water pumphouse (located on the west side of Millstone Point and north of the Millstone 2 intake). The water is pumped through the condenser to condense steam exhausted from the turbine generator.
During its passage through the condenser, the circulating water will be heated to approximately 9.4 C (17 F) above its inlet temperature.
Small amounts of radioactive wastes are released after treatment to reduce the radioactivity to a level below the concentrations permitted by Federal Regulations (Section 3.5).. Circulating water, after passing through the condenser, will be used to dilute the treated radioactive waste and small quantities of chemical wastes.
Sections 3.6 and 3.7 summarize the maximum cumulative chemical releases expected from operations at the site.
i The heated circulating water will be discharged into the quarry (which is located on the southeast extremity of Millstone Point) where it will be combined with the heated discharges from Millstone 1 and 2.
Section 3.4 gives details of the heat dissipation system.
The service water, in a manner similar to the circulating water, ps will be used as the coolant for various heat exchangers and will not t
I come in contact with radioactive material or components in the unit.
After passing through these heat exchangers, the service water will 4
Amendment 2 3.3-1 April 1983
MNPS-3 EROLS be mixed into the circulating water and discharged first to the quarry and ultimately to Long Island Sound.
Because of the relativelf small service water flow and temperature rise, this discharge will not increase the temperature of the circulating water at the quarry discharge.
3.3.2.2 Domestic Uses During initial startup of the unit, approximately 3,217 cubic meters (850,000 gallons) of freshwater will be taken into the
- unit, demineralized, and stored in five tanks for use in various systems.
In general, the demineralized water used in the unit will be recycled.
Approximately 545 cubic meters (144,000 gallons) per day will be required as makeup for losses from the unit systems due to floor and equipment washdowns, steam generator blowdown, valve stem leakages, and evaporation from open systems and tanks and normal maintenance activities.
Details of the unit process of the water treating system and the quality of its waste discharge are discussed in Sections 3.6 and 3.7.
In addition, approximately 13.2 cubic meters (3,500 gallons) per day will be required for use in the unit's sanitary waste system.
3.3.2.3 Consumptive Use Various process water streams used in the plant are recycled within the plant for reuse.
Since the. unit uses once-through circulating water system, consumptive use due to evaporation of cooling water is minimal.
Major consumptive uses in the plant are those used in the process of radioactive solid waste and sanitary and potable water system.
Approximately 29.5 cubic meters (7,800 gallons) per year of water are consumed for radioactive solid waste process, and 13.2 cubic meters (3,500 gallons) per day are consumed for potable and sanitary purposes. Details of the sanitary and potable water systems are discussed in Section 3.7.

3.4 HEAT DISSIPATION SYSTEM (Q
3.4.1 Circulating Water System The Millstone 3 circulating water system (Figure 3.4-1) pumps salt water from Niantic Bay through a single-pass, triple shell condenser at a rate of 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),
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.
.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 (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/sq leg cm (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 fi-h trays on the screens into a fish trough.
The debris is re..oved from the trash trough by a mo*orized 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.

The circulating water flows from the six circulating water pumps to the condenser through six independent 183-meter (600-foot) long 3.4-1
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 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 ',
- However, in the event that thermal backwashing or tube cleaning proves unsuccessful, provisions for a chlorine i:.jection 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 l
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.
Amendment 2 3.4-2 April 1983
HNPS-3 EROLS Six independent condenser tube cleaning systems, one for each condenser flow path, are installed to provide a mechanical means of cleaning the condenser tubes and thus provide for the control of biofouling in the condenser. Each system consists of elastomeric sponge-rubber balls oversized in comparison to the condenser tube diameter, which are injected into the circulating water system upstream of the condenser.
The balls are forced through the condenser tubes by the differential pressure between condenser inlet I

/~N A gaseous chlorine solution is injected into the service water system
\\~-}-
to control biofouling. Chlorination of the service water occurs
-(
three times a day for 30-minute periods, for a total of 1 1/2 hours per day. 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 discharged to 2
the quarry is maintained at 0.1 ppm average or less. After mixing QE291.9
^
with the quarry water, the concentration of free available. chlorine is reduced-to a concentration below 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 i
below that which would occur through dilution alone.
It is estimated that approximately 3,720 kg/yr (8,200 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 s)
capacity of 379 liters / min (100 gpm),
for the Millstone 3 plant s
areas.
Cil 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
- s outage, the steam generator shells may be drained through the blowdown lines to the condensate polishing system waste Amendment 2 3.6-3 April 1983

neutralization sump or, if required, to the low level waste drain 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.
The bulk of the discharges occurs during the 6 weeks prior to refueling. Distillate from the boron evaporator is treated using the boron demineralizers, baron demineralizer filter, and the effluent filters. Baron is the only constituent in this waste.
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 manner 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 waste 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 blowdown is processed by the waste evaporator.

5.2.2.1.2 Sediment Uptake Models
{
Sediment uptake reduces radionuclide concentrations as predicted by the two-dimensional vertically averaged numerical model.
- However, because only limited information is available on sediment uptake, the i
effect of this process is conservatively neglected.
It should be noted that such uptake could result. in additional pathways of radioactivity to' man-and biota.
'These pathways and the doses resulting from -sediment uptake are considered in Sections 5.2.1 and a
5.2.3.
f 5.2.2.1.3 Water Use Models The nearest industrial user of Long Island Sound water is the Pfizer -
Corporation, located 8.8 km (5.5 miles) east-northeast of -Millstone Point.
Normal or accidental releases from the site are not expected l
to affect this plant because of its distance from the Millstone site.
There are no planned changes in water use or flow regulation in
{-
Niantic -Bay or Long Island Sound waters that could have an appreciable effect on far-field dilution estimate _during the
[
operating life of the station.
5.2.2.2 Groundwater Models
! V There are no routine discharges of liquid effluents to ground-water; I
therefore, groundwater models are not used in these analyses.
[
5.2.3 Dose Rate Estimates for Biota Other than Man The exposure pathways and parameters-are discussed in previous l
subsections. The doses to terrestrial and aquatic organisms other than man resulting from radionuclide effluents are presented in the l
following subsections and tables. Calculated internal and external' dose rates to biota are based on the model and assumptions presented in Appendix F.
5.2.3.1 Doses through Gaseous Pathways Table 5.2-6 presents the calculated doses to biota other than man from gaseous pathways.
These doses are calculated for a terrestrial animal residing in the vicinity of the plant. The dose rates for these animals are based on methodology used to calculate external dose rates for man.
5.2.3.2 Doses through Liquid. Pathways Table 5.2-6 shows the maximum calculated doses from submersion in water at the edge of the initial mixing zone and exposure to sediments at the closest accessible shoreline from the point of
/
discharge. Table 5.2-7 shows the maximum calculated internal doses due to the bioaccumulation process.

MNPS-3 EROLS 5.2.4 Dose Rate Estimates for Man Calculated doses to the maximum offsite individual and for the population within the 80-km radius for the year 2010 are based on the l2 gaseous and liquid releases shown in Sections 3.5.2 and 3.5.3.
The Q470.2 mathematical models and assumptions used to calculate these doses are given in Appendix F.
5.2.4.1 Gaseous Pathways Tables 5.2-8 through 5.2-19 present the calculated doses to maximum individual from gaseous pathways.
These tables present the calculated total body and organ doses for four age groups - adult, teen, child, and infant. The analysis was performed for locations where an existing resident, milk cow, and milk goat were identified.
Each analysis considers existing and potential pathways at the specified location.
For example, it was assumed that a garden existed at all locations which had milking animals.
The maximum individuals residing' at those farms were analyzed for inhalation, ground deposition, ingestion of vegetation, and consumption of milk.
Tables 5.2-8 through 5.2-11 present the doses to the maximum individuals liting at the estimated maximum resident location (0.81 km east northeast).
Tables 5.2-12 through 5.2-15 present the estimated doses to the maximum individual living at the maximum goat milk animal location (2.4 km north northeast).
Tables 5.2-16 through 5.2-19 present doses to the maximum individuals from consumption of cow milk.
Table 5.2-23 presents the comparison of the maximum individual calculated doses from gaseous effluents to the design objectives of Appendix I limits (U.S. URC 1976).
Annual calculated gamma air dose and beta air dose values were determined. Table 5.2-23 compares these values to the 10CFR50 design objective limit values.
The maximum values occurred at the site boundary in the east northeast direction at a distance of 650 meters from Millstone 3.
5.2.4.2 Liquid Pathways Tables 5.2-20 through 5.2-22 present the calculated doses to the maximum individual from liquid pathways.
The tables present the calculated total body and organ doses for three age groups adult, teen, and child.
It was assumed that an infant would not exceed the doses calculated for a child and, therefore, a separate table was not provided.
Table 5.2-23 presents a comparison of the maximum individual calculated doses from liquid effluents to the design objectives of Appendix I limits (U.S. NRC 1976).

MNPS-3 EROLS rs 5.2.4.3 Direct Radiation from Facility
?
I The station radiation shield analysis is based on conservative operating parameters, which include a nuclide inventory associated with 1 percent fuel defects. The shield walls are designed to meet the operational dose criteria of 0.25 mrem per hour in the yard areas.
The most significant structures which contribute to the yard dose rate are the containment fuel building, vaste disposal building, auxiliary building, refueling water storage tank, and the boron recovery tanks.
The calculated dose rate levels in the unrestricted areas are based on full power normal plant operations assuming fuel defects producing expected quantities and concentrations of radioactive nuclides consistent with NUREG 0017.
The annual dose rate at the site boundary is approximately 0.43 mrem per year. The annual dose rates computed as a function of distance from the site boundary are given on Figure 5.2-4.
5.2.4.4 Annual Population Doses 5.?.4.4.1 Eighty-km Radius Population Doses Population dose commitments are calculated for all individuals living within 80 km of the facility, employing the same models used from
()
individual doses (Regulatory Guide 1.109).
LI Table 5.2-24 presents the calculated annual total body and thyroid doses from gaseous and liquid pathways to the population projected for the year 2010, residing within an 80-km radius of the site. Due l2 to the long travel times and high dilution factors involved in Q470.3 analyzing population doses from liquid pathways out to the 80-km radius, the dilution factor and travel time to the 16-km radius is conservatively assumed to be representative of the 80-km radius.
Thus, population doses from ingestion of aquatic foods, swimming, and boating will be determined using the dilution factor and travel time calculated for the 16-km radius.
l 5.2.4.4.2 Contiguous U.S. Population Doses In addition to the 80-km (50-mile) radius population doses, population doses associated with the export of food crops produced within the 80-km (50-mile) region and the atmospheric and hydrospheric transport of the more mobile effluent species, such as noble gases, tritium, and carbon-14, uere calculated.

MNPS-3 EROLS 5.2.4.5 Liquid Pathways For liquid releases, it was assumed that the maximum individual will consume fish and invertebrates caught at the edge of the initial mixing zone (EI!L'). This location was also used in calculating the doses from swimming and boating. Shoreline recreation was analyzed at the closed shore on the Long Island Sound.
s The calculated n aximum organ dose to the maximum individual from liquid pathways we.s 5.6E-03 mrem per year to an adult thyroid.
This dose was primacily a result of the consumption of fish and invertebrates.
It was assumed that the adult consumes 21 kg per year of fish and 5 kg per year of invertebrates, which were caught at the edge of the init:.al mixing zone.
5.2.4.6 Annual Population Doses The calculated annual doses for the population residing within an 80-km radius of the site are presented in Table 5.2-24.
For the liquid effluents, the calculated whole body and thyroid doses are 1.3E+00 and 6.5E+00 man-Rem per year, respectively.
.The calculated doses fro.n gaseous releases are 4.7E+00 man-Rem per year whole body and 7.2E+00 man-Rem per year thyroid.
These doses were calculated for a projected population in the year 2010 of 3.3 million people within 80 km of the site.
Annual population doses to the contiguous U.S. from the liquid and gaseous pathways are given in Table 5.2-25.
The calculated doses to the U.S. population are 2.3E+01 man-Rem to the whole body and 3.lE+01 man-Rem to the thyroid.

S.3 EFFECTS OF CHEMICAL AND BIOCIDE WASTE DISCHARGES 5.3.1 Water Quality Standar.ds 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 Millstone Nuclear Power Station are classified as
... suitable for bathing, other recreational purposes, Class SB, 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 Millstone 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 Millstone 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 n_
within the plant.
This water is withdrawn from Niantic Bay and is (d
discharged to Long Island Sound, via the quarry cut. The chemical
)
i 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 demineralizers and of the condensate l
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 Sound: 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 l
Sound chemical water quality resulting from the discharge of once-through cooling water will be minimal. The impact of the waste heat in this discharge is discussed in Section 5.1.3.
As discussed in Section 3.6, an average of approximately 242,000 liters (64,000 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 Q
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
/
j this waste is less than that of the intake water, and, therefore, there 5.3-1
MNPS-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 gre-*.er than in the circulating water; however, assuming that this waste is discharged to the circulating water *unnel at 379 liters / min (100 gpm), the resulting increase in the circulating water discharge concentrations is less than 0.1 mg/1.
The discharge impact of neutralized makeup demineralizer regeneration wastes 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 neutralized condensate polisher rege..eration wastes may be discharged to circulating water.
These wastes will contain approximately 3,930 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 water system is chlorinated three times a day for 30-minute periods, l2 totaling 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> per day.
The concentration of free available chlorine in the service water at the point where the service water and circulating water is discharged to the quarry is maintained at or less than 0.1 ppm, average.
After mixing with the quarry water, this concentratien is reduced through dilution below detectable limits for free available chlorine.
The chlorine demand of the circulating and quarry water reduces the chlorine concentration, such that essentially no free residuel chlorine will be discharged to Long Island Sound.
5.3.3 Effects of Chemical and Biocide Discharges on Aquatic Biota The chemical constituents of the discharge of Millstone 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 Millstone Point.
Chlorination is not used to control biofouling in the circulating water system of Millstone 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 Millstone 3; however, its use is not anticipated unless the mechanical tube cleaning system should prove ineffective in controlling fouling of the condenser tubes.
Chlorination for approximately 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> on a daily basis is used to l2 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 is approximately 0.1 ppm average.
After mixing with the quarry water, concentration of free available Amendment 2 5.3-2 April 1983

Question No. Q231.1 (Section 2.5)
Revise the Environmental Report to accurately reflect the results of the site faulting investigations as presented in the FSAR.
Page 2.5-2 (second and third paragraphs) of the ER is incorrect (based on the more detailed geologic submittal presented in the FSAR) as far as:
1.
The number of faults mapped at the Unit 3 site, i
2.
The age of most recent faulting, and f
3.
The type of faulting.
- Response, EROLS Section 2.5 has been revised in Amendment 2 to reflect consistency with the FSAR.

Description of floodplains, as requested by Executive Order 11988, Floodplain-Hanagement, have not been provided. The definition used in the Executive Order is:
Floodplain:
The lowland and relatively flat areas adj oining inland and coastal waters including flood prone areas of offshore
- islands, including at a minimum that arca subject to a one percent or greater chance of flooding in any given year.
a.
Provide descriptions of the floodplains adjacent to the site.
On a suitable map (s) provide delineations of those areas that will be flooded during the one percent (100-year) flood, both before and after plant construction or operation, b.
Provide details of the methods used to determine the floodplains in response to a. above.
Include your assumption of, and basis for, the pertinent parameters used in the computation of the flood flows and water elevations.
If studies approved by the Federal Insurance Administration (FIA) are available for the site and other affected areas, the details of the analyis used in the reports need not be supplied. You can instead provide the reports from which you obtained the floodplain information.
c.
Identify, locate on a map and describe all plant structures and topographic alternations in the floodplains.
d.
Discuss the hydrologic effects of all items identified in response to c. above. Discuss the potential for altered flood flows and levels, offsite.
Discu.s the effects on offsite areas of debris generated from the site during flood events.
e.
Provide the details of your analysis used in response to d.
above.
The level of detail is similar to that identified in item b. above.

4 Question No. Q240.2 (Section 7.1.9)
I Calculate the radiological consequences of a liquid pathway release from a postulated core melt accident. The analysis. should assume, unless otherwise justified, that there has been a penetration of the reactor basemat by the molten. core mass, and that a substantial portion of I
radioactivity. contaminated sump water was released to the ground. Doses
-shculd be compared to those calculated in the Liquid Pathway Generic Stt 'y (NUREG-0440,1978). Provide a summary of your analysis procedures and the _ values of parameters used (such as permeabilities, gradients, populations affected, water use).
It is suggested that meetings with-the staff of the Hydrologic Engineering Section be arranged so that we may share with you the body of information necessary to perform this i-analysis.
Response
As stated in Section 7.1.9 of the Millstone 3 EROLS, "The analyses of the probabilities and consequences of accidents beyond the design bases of.the Millstone 3 plant will be comprehensively discussed in the relevant portions of the Millstone 3 Probabilistic Safety _ Study (PSS),
~
which the _ applicants presently estimate will be _ completed within i.
6 months after the docketing of the FSAR" (August 1983).

On a similar basis, indicate changes in plant or plant component design, location or operation that have been made or planned since the construction permit review.
Response
A review of the ERCPS and EROLS will be conducted to document substantive informational changes since 1973 (ERCPS).
Significant changes in design, new information, and changes in conclusions or impacts will be presented in Tabular (matrix) form in June 1983.

FRC-Letter: January 31, 1983 s'v' Question No. QE291.3 (Section 2.4)
The information on metals in Section 2.4 doesn't always indicate the location when metals concentration values are discussed. These data are helpful when reviewing this section and should be provided.
Response
As discussed in EROLS Section 2.4.3.4.3 Trace Metals,,an ongoing monitoring program was established by NUSCO to determine potential impacts of the Millstone Nuclear Power Station on trace metal concentrations in Long Island Sound.
Samples were collected from four locations in the vicinity of the stationr Hillstone 1 Intake; Quarry Cut (station discharge); Giants Neck; and Twotree Island.
- However, in presenting the 1974 baseline study results, the location of the sampling was not always indicated.
It is supplemented by the following.

NRC Letter: January 31, 1983 nl Question No. QE291.4 (Section 2.4)
The information in Section 2.4 and elsewhere in the ER is referenced to the 1974 water quality program. The ER in Section 6 indicates that more recent surveys have been conducted.
Indicate whether and to what degree the analyses and conclusions drawn in the ER with regard to site area water quality would be changed by this additional information.
Response
The comprehensive baseline water quality survey was conducted during 1974 only by The Research Corporation of New England, Inc.
(TRC).
The objective of more recent surveys is to determine possible contributions
-by the Millstone Station condenser cooling system to the heavy metal concentrations in adjacent Long Island Sound. The heavy metals selected for analyses in seawater include copper, zinc, iron, chromium, and lead.
The results are discussed in Section 2.4.3.4.3 and presented in Table 2.4-5.
The analyses and conclusions drawn in the ER with regard to site area water quality are not changed by this additional information (NUSCO 1982).

Question No. QE29; 8 (Section 3.4.1)
Describe the design and likely operational parameters (e.g., frequency, duration and amount of biocide addition) of the chlorine injection system for the circulating water system.
Response
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 Amertap system to provide condenser slime control.
Should a more extensive, continuous chlorination program be required to control hardshell 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 Guidelined in 40CFR423.

Based on operating experience with Units 1 and 2 or on other bases, provide an estimate of the total residual chlorine concentration of the service water system at the point where it discharges into the discharge tunnel.
Desponse:
A chlorination study was conducted in 1976 and 1977 for Millstone Units 1 and 2(1) to correlate levels of total residual chlorine at the quarry cut with levels of free available chlorine at the condenser outlets (discharge structures) into the quarry.
No significant correlation of the total residual levels at the quarry cut and the free available levels at the discharge structure can be demonstrated from the available data.
It is estimated that the total residual chlorine concentration of the Millstone 3 service water system at the point where it discharges into the Unit 3 discharge tunnel will be 2.5 ppm (the worst case). The 2.5 ppm concentration is an extremely conservative estimate.
The service water chlorination equipment is designed to chlorinate the service water to a concentration of 2.5 ppm.
If it is assumed no chemical reaction occurred between the chlorine and marine organisms (i.e., no chlorine is consumed during chlorination process),
the concentration will remain the same at the point where the service water discha'cges into the discharge tunnel.
The service water (30,000 gpm) will mix with the circulating water (912,000 gpm) in the discharge tunnel.
Even in this worst case, it is calculated that the total residual chlorine will be reduced to 0.03 ppm at the discharge outfall structure into the quarry.

Question No. QE291.18 (Section Appendix C)
Provide a copy of all reports available from the effluent toxicity testing program.
Indicate which "other suitable organisms indigenous to the Millstone area" will be used in effluent toxicity testing.
Response
No formal report providing summaries and interpretation of data from the effluent toxicity testing program has been prepared to date.
Development of the experimental testing facility was not completed until early 1981 when the first series of tests on sheepshead minnow (Cyprinodon variegatus) were begun. During 1982, the program scope was expanded to include Mysidopsis bahia. Preparation of a report on these results is being planned for later in 1983.
Copies vill be made available.
Other indigenous species currently being considered are the silverside (Menidia menidia), an abundant local shore-zone forage fish, and winter flounder (Pseudopleuronectes americanus) which would be tested as larvae or juveniles. Because the experimental facility would have to be modified appreciably to accommodate the lower water temperature requirements of flounder, tests using this species will probably be delayed for several years.

MNPS-3 EROLS NRC Letter: January 31, 1983 Question No. QE320.1 (Sections 8 and 11)
Provide the following:
A production cost analysis which shows the difference in system production costs associated with the availability vs. unavailability of the proposed nuclear addition.
- Note, the resulting cost differential should be limited solely to the variable or incremental costs associated with generating electricity from the proposed nuclear addition and the sources of replacement energy.
If, in your
- analysis, other factors influence the cost differential, explain in detail.
a.
The analysis should provide results on an annual basis covering the period from initial operation of the first unit through five full years of operation of the last unit.
b.
Where more than one utility shares ownership in the proposed nuclear addition or where the proposed facility is centrally dispatched as part of an interconnected pool, the results of the anlaysis may be aggregated for all participating systems.
c.
The analysis should assume electrical energy requirements grow at (1) the system's latest official forecasted growth rate, and (2) zero growth from the latest actual annual energy requirement.
d.
The analysis should assume two capacity factors for the nuclear facility (1) 50 percent average annual capacity factor and (2) applicant's currently anticipated average annual capacity factor.
e.
For each year (and for each growth rate scenario) the following results should be clearly stated:
(1) system present worth production costs with the proposed nuclear addition available as scheduled: (2) system present worth production costs without the proposed nuclear addition available:
(3) the capacity factor assumed for the nuclear addition (4) the average fuel cost and variable O&M cost for the nuclear addition and the sources of replacement energy (by fuel type)--both expressed in mills per kWh: and (5) the proportion of replacement energy assumed to be provided by coal,
- oil, gas, etc.
for both purchased power and for self-generated power. The base year for all costs should be identified.
Response
On March 26, 1982, the Nucler Regulatory Commission ammended its rules and regulations to provide that an applicant for a license to operate a nuclear power plant need not include in its Environmental Report -
Operating License Stage any discussion of "need for power or alternative QE320.1-1

dated January 31,
- 1983, to which the
" Requests for Additional Information" were attached, Darrell G. Eisenhut, Director, Divison of Licensing, Office of Nuclear Reactor Regulation, indicated that the Staff will not include need fcr power and alternative energy sources issues in the licensing review for Millstone 3.
Accordingly, because this question is in essence an inquiry into the need for power and alternative energy sources, a response is not necessary.

Question No. Q470.1 (Section 2.1)
Provide the following distributional data for each of the 22-1/2 degree radial sectors centered on the sixteen cardinal compass directions for the radial distances of 1.6, 3.2, 4.8, 6.4, 8.0, 16.1, 32.2, 48.3, 64.4, and 80.4 km for the reactor:
1.
Present annual meat production (kg/yr) 2.
Present annual milk production (1/yr) 3.
Present annual vegetable production (kg/yr)
Response
Estimated production of beef, milk, and vegetables (corn) is listed by distance and direction in Tables Q470.1-1, Q470.1-2, and Q470.1-3.
Corn was discussed in lieu of all vegetables because garden vegetables were not given in quantities and corn was uniformly distributed throughout the three states.
Since data was only available as state totals in Connecticut and Rhode Island and as county totals in N.Y.,
distributions, with the exception of those within 8 km, were calculated f 's by assuming that production was evenly distributed over either the state
(
)
or the county land area.
Production within 8 km was distributed by first sector distance (see Table 2.1-22 of the EROLS), and actual survey data of beef, dairy, and vegetable gardens was used.
