Question No. QE290.2 (Section 2.1)

During the public meeting held on July 21, 1983, to gather information on environmental concerns over Millstone Unit 3 M.A. Cotter of 50 New, Shore Road in Pleasure Beach indicated that representatives of Northeast Utilities visited his residence for the purpose of obtaining noise level data in response to his complaint regarding noise from the Millstone plant site. Provide the noise level data gathered, if any, in response to Mr. Cotter's complaint.

Indicate the status of construction (i.e., types of activities) ongoing at the Millstone site during noise measurements and similarly indicate the operational status for Millstone Units 1 and 2.

Indicate any follow-up actions taken to resolve Mr. Cotter's noise complaint.

Response

Mr. A. Cotter's residence has been visited with the intent of assessing the noise levsl; however, a noise survey was not conducted in response to his complaint. In response to a complaint by J. Sexton, on October 6, 1983 daytime and nighttime sound level measurements were recorded to determine the background levels created by the Millstone Nuclear Power Station in the vicinity of Millstone

~

Road and Windworthway in Niantic, Connecticut. A-weighted, linear l and one-third octave band readings were taken in front of 283 N- '

Millstone Road, Niantic, Connecticut, J. Sexton residence. The levels measured are below the maximum levels set by the State of Connecticut, Office of Noise Control. The results of this survey were submitted under separate cover on March 15, 1984.

Millstone Unit 1 was operating at 100 percent power on October 6, 1983 and Unit 2 was down for refueling. The following construction activities were in progress during October 1983; however, specific activities occurring on October 6, 1983 are not available.

October 1983 In the containment structure, work on the upper pressurizer shield walls and the snubber installation continued as did piping, instrumentation, HVAC, and electrical work. In the north and east yard, piping continued. For the hydrogen recombiner building, electrical installation continued. In the fuel building, structural work on the roof, building walls, and the railroad canopy superstructure continued as did installation on piping, HVAC, and electrical. In the auxiliary building, work proceeded on painting, ironwork, piping, electrical work, and HVAC. For the waste disposal building, work on the interior walls continued as did piping, electrical, and HVAC installation. In the southwest yard, work on q nitrogen and hydrogen storage equipment, piping, and electrical work continued. In the turbine building, turbine assembly continued as did electrical, piping, and instrumentation installation. In the Revision 1 QE290.2-1 April 1984

MHPS-3 EROLS main steam valve building, piping, electrical, and HVAC work continued. Piping, electrical, and HVAC work continued in the emergency generator enclosure. In the engineered safety features building, piping, electrical, and HVAC work continued. Piping, electrical, and HVAC work continued in the condensate polishing enclosure. In the control building, piping, electrical, and HVAC work continued. In the service building, erection of masonry walls, finish plumbing, piping, instrumentation, electrical, and HVAC work continued. For the auxiliary boiler building, piping, electrical, and HVAC work continued. Piping and electrical work continued for the intake structure. In the main transformer areas, work continued on support steel for nonsegregated bus duct; installation of iso-phase bus duct and buried conduit continued.

As described in the Environmental Report - Operating License Stage (EROLS), Section 2.7, two 3-day ambient noise surveys were conducted for the preparation of the report. One was coaducted in October 1979 and the other in April 1980. The purpose of the surveys was to characterize the ambient noise environment in the residential areas surrounding the Millstone site (see Tables 2.7-1, 2.7-2 and 2.7-3 of the EROLS). The results of the surveys were compared with the last ambient noise survey in 1970 and used to estimate total sound levels from Hillstone Units 1, 2, and 3 (see Table 5.6-1 of the EROLS).

As the time of the surveys Millstone Units 1 and 2 were in operation and the following construction activities were in progress.

October 1979 h

Concrete placemcat far the east vall beam, personnel hatch, and slab at elevation 24 feet :n the containment was completed. Main rebar installation for the crane wall was completed, while concrete and embedment installatioa continued. Cor.struction of stairs to elevation 3 feet-8 inches was initiated. The exterior wall has been poured to a maximum elevation of 64 feet-10 inches and the crane wall to elevation 91 feet. Work on piping and pipe supports, the refueling cavity liner and dome liner continued.

In the auxiliary building, the walls to elevation 41 feet-6 inches were completed and initial concrete pours were made for the slab at 43 feet-6 inches, while shoring, embedments, and rebar continued.

Rebar and conduit installation began for the slab at elevation 4 feet-6 inches, Section 3, and work on piping and pipe supports continued inside the building. The boren evaporator was set in place at elevation 24 feet-6 inches.

Question No. QE290.3 (Section 2.1)

Provide information on noise related complaints associated with operation of the Millstone Nuclear Power Station. Include date and time of complaint, the location of the complaintant, the nature of the complaint and the actions taken by Northeast Utilities to resolve the complaint and to prevent its reoccurrence.

Response

There is no formal procedure for the handling of noise complaints.

The Public Information Officer for the Millstone Nuclear Power Station is generally the point of contact for complaints from the local community. The Public Information Officer forwards the complaints to the Statien Superintendent or the Superintendent, New Site Construction. Noise complaints are dispositioned jointly by Public Information and the Plant. Dispositioning of complaints usually involves an explanation to the party complaining of off normal events responsible for increased noise levels and corrective action where appropriate. For example, in response to complaints received regarding the public address system at the site, personnel at the site were directed not to use the public address system between 6:30 p.m. and 8:00 a.m., except for emergencies. In

' f' . addition, specialists were assigned to review the position,

( -

direction,- and volume of each of the loudspeakers. This resulted in a substantial reduction in the overall offsite noise caused by the daytime use of the public address system. A noise survey was conducted in response to.one complaint, as noted in the response to NRC Question E290.2; however, noise surveys are not conducted in

-response to complaints as a matter of routine.

HNPS-3 EROLS j w., 3.5.2 Liquid Radwaste System

\

\ ) The liquid radwaste system collects, stores, monitors, and reduces the concentration of radioactive nuclides in liquid effluents to a level as low as reasonably achievable. The liquid radwaste system discharges to the circulating water discharge tunnel or to the primary grade water for reuse.

Figure 3.5-1 is a flow diagram of the system, showing interconnections with other systems. Table 3.5-8 shows the component capacities and flow rates. Table 3.5-9 gives the estimated quantities and flow rates to the system from liquid radwaste sources.

Table 3.5-10 lists minimum expected decontamination factors and holdup times.

The liquid radwaste system consists of the waste evaporator system and regenerant evaporator system. These subsystems, as well as the boron recovery system, are discussed in the following sections. More detailed information is contained in Millstone 3 FSAR, Section 11.2.

5.5.2.1 Waste Evaporator System The waste evaporator system collects liquid radwaste from the sources identified in Table 3.5-9 and produces a distillate suitable for reuse or discharge. The high level waste drain tanks store the liquid radwaste prior te processing in the waste evaporator. The r' ' waste evaporator is designed with an external reboiler, a large

( )S liquid disengaging space, a vapor-liquid separator, and a tray

'~~

section. These features combine to form a system with extremely high separation factors for nonvolatile nuclides.

Distillate from the waste evaporator is collected in waste test tanks, sampled, and, if within allowable chemistry and activity limits, is recycled to the primary grade water tanks for reuse in the unit. If required by tritium or water balance requirements, distillate may alternately be discharged via the circulating water discharge tunnel.

If samples indicate that the distillate is unacceptable for reuse or discharge, it is either passed through the waste demineralizer and resampled, or sent back to the high level waste drain tanks for reprocessing. The demineralizer is a bed of mixed ion exchange resins in the H+ and OH- form.

It is expected that the liquid from the waste test tanks will be total 3y recycled. However, for the purpose of evaluating the radiological impact on the environment. 10 percent of this process waste is assumed to be discharged in accordance with NUREG-0017.

Assurance that waste above activity limits is not inadvertently discharged to the environment is provided through sampling of the effluent prior to discharge and radiation monitoring of the effluent stream.

3.5-5 i

MNPS-3 EROLS Isotopic analysis is performed on each batch prior to discharge and 7

the total activity discharged is recorded. Detailed administrative records of all radioactive releases are maintained. Table 3.5-11 presents annual expected liquid discharge activity for significant isotopes. Table 3.5-12 presents radioactive liquid concentrations from various input streams.

Waste evaporator bottoms are allowed to concentrate until either approximately 25 percent solids by weight or an activity level to be determined by the characteristics of the container used to ship the evaporator bottoms offsite is accumulated. Evaporator bottoms are pumped to the solid radwaste system (Section 3.5.4).

3.5.2.2 Regenerant Evaporator System The regenerant evaporator system collects, chemically treats, and concentrates liquid waste from the condensate demineralizer system.

Radioactivity exists in the system only after a primary to secondary leak from the reactor coolant to a steam generator. The system collects radioactive liquid waste from the sources identified in Table 3.5-9 and produces a distillate. The regenerant evaporator feed tanks store any' liquid radwaste prior to processing in the regenerant evaporator. The regenerant evaporator is similar to the waste evaporator.

During evaporator operation, the distillate leaving the demineralizer filter is continuously sampled for radioactivity, conductivity, and pH. If either the radioactivity, conductivity level and pH is

  • unacceptable, the distillate is automatically returned to the feed tanks. If the distillate is acceptable, it is forwarded to the condensate surge tank or to the condensate storage tank. The distillate can also be discharged offsite through the circulating water discharge system.

The regenerant evaporator is operated so as to discharge bottoms at about 25 percent by weight solids concentration to the regenerant bottoms holding tank for storage and then to the waste solidification system.

3.5.2.3 Boron Recovery System The boron recovery system processes reactor coolant to recover primary grade water and boric acid for reuse or disposal. The liquid that enters the boron recovery system is a result of the feed and bleed operations necessary to maintain the boron concentration in the reactor coolant at the desired level. This liquid is reactor coolant letdown from the chemical and volume control system (CHS) and has been passed through a mixed bed demineralizer and from the reactor plant gaseous drains system (DGS).

In the boron recovery system, the reactor coolant letdown passes through the cesium removal ion exchangers, boron recovery tanks, and the boron evaporator. The distillate is transferred to either the primary grade water system for reuse or to the circulating water Amendment 7 3.5-6 April 1984 2

HNPS-3 EROLS g discharge tunnel (via the liquid radwaste system). The bottoms from (V i the boron evaporator are filtered and sent either to 'he CVCE for reuse or to the solid radwaste system for solidificattna and offsite shipment.

3.5.3 Radioactive Gaseous Waste System The gaseous radwaste system consists of the process gas stream (hydrogenated) and the low activity process vent strean (aerated).

Each of the Millstone site units has a separate gaseous radwaste system, as described in this section. Figure 3.5-2 is a flow diagram of the system, which shows interconnections with other systems.

Table 3.5-13 shows the component capacities. Table 3.5-14 shows effluent releases from each release point.

The gaseous radwaste system treats specific gas streams The treated effluent is discharged to the Millstone 1 Stack.

In addition, the exhaust from the reactor plant ventilation system is discharged to the ventilation vent. These exhausts come from the auxiliary building ventilation system, the waste disposal building ventilation system, the fuel building ventilation system, the containment purge air system, and the containment atmosphere filtration system. Exhausts from the engineered safety features (ESF) building are vented from a release point atop the south wall of p the building, but in terms of gaseous releases reports in i 4 Table 3.5-14, releases from the ESF building are included in the V auxiliary building releases as part of the normal composite ventilation releases from the station buildings.

Figure 3.5-3 is a diagram for the reactor plant ventilation system.

Table 3.5-15 lists the expected decontamination factors for the reactor plant ventilation system. Table 3.5-16 defines the release points and rates.

The two portions of the radioactive gaseous waste system and the ventilation systems are discussed in the following sections. More detailed 11 formation is contained in Millstone 3 FSAR, Section 11.3.

3.5.3.1 The Process Gas (Hydrogenated) Portion of the Radioactive Gaseous Waste System The process gas (hydrogenated) portion dehydrates the noncondensable fission product gas stream, removes radioactive iodine, and provides for activity reduction of radioactive xenon and krypton. It can also recycle the purified hydrogen stream back to the reactor coolant system through the volume control tank or release it to the atmosphere via interfacing systems.

The reactor coolant letdown, containing the dissolved hydrogen and fission product gases, is directed to the degasifier. The liquid

^ '

collected by the reactor plant gaseous drains system is also directed to the degasifier.

3.5-7

MNPS-3 EROLS Effluent gases from the degasifier primarily contain hydrogen and water vapor. A small amount of nitrogen and traces of xenon, krypton, and iodine are also present in the effluent gases.

These gases and any hydrogenated gas stream from the reactor plant gaseous vent header are dehumidified in the process gas refrigerant dryers and passed through and filtered by the process gas charcoal bed adsorbers (to limit the buildup of long-lived fission product gases dissolved in the reactor coolant) and released to the environment via the Millstone 1 Stack. The charcoal beds are designed to delay xenon isotopes for a minimum of 142 days and krypton for 6 days. In addition, a decontamination factor of 106 for iodine is obtained during passage through the charcoal beds. The charcoal is divided evenly between two vertical tanke in series.

3.5.3.2 Process Vent Portion of the Radioactive Gaseous Waste System The process vent portion collects, dehydrates, and discharges aerated gas streams to the Millstone 1 stack. It also collects relief valve effluents from the degasifier, liquid waste evaporator, and boron evaporator and discharges them to the reactor plant ventilation vent.

The releases are monitored prior to discharge.

3.5.3.3 Reactor Plant Ventilation Systems The reactor plant ventilation systems consist of the auxiliary building ventilation system, the waste disposal building ventilation system, the fuel building ventilation system, the containment purge air system and the containment atmosphere filtration system. These 7

systems are described in the following sections and shown on figures contained in Millstone 3 FSAR, 0"ction 9.4.

3.5.3.3.1 Auxiliary Building Ventilation System The exhaust may be discharged to the atmosphere filtered or unfiltered. The auxiliary building exhaust system includes one normal exhaust and two fan-filter trains. Each filter bank includes an electric heating coil, prefilter, a carbon adsorber and two high efficiency particulate air (HEPA) filters (one upstream and one downstream of the carbon adsorber). The prefilters have a minimum filter efficiency of 80 percent based on ASHRAE Standard 52-68. The carbon adsorbers are of the gasketless nontray type to facilitate replacement. The carbon adsorber is designed for maximum flow velocity of 12 meters / min (40 fpm) to give sufficient residence time (0.25 sec/5.1-cm (2-inch] bed depth). Anticipated operational pressure surges will not affect the carbon adsorbers. The HEPA filters have a minimum filter efficiency of 99.95 percent when filtering particulates that are 0.3 micron or larger.

,-~s shipping container at the fill station. Then, waste concentrates are

( ) pumped into the container along with catalyst. Solidi 11 cation occurs in the container.

Resins sluiced from demineralizers and ion exchangers are stored in the spent resin hold tank. The resins are then slurried to a 2.83-cubic meter (100-cubic) foot high integrity container, where they are allowed to settle. Excess water is removed by the spent resin dewatering pump and returned to the resin dewatering tank.

Dewatered resin in high integrity containers in shielded shipping casks is suitable for offsite shipment.

Spent filters, contaminated tools, and other incompressible contaminated solid wastes are placed in 2.83- to 8.50-cubic meters (100- to 300-cubic foot) shipping containers. Either evaporator bottoms or water plus a solidification agent are added to the shipping container to immobilize the waste.

The system is designed to prevent external contamination of the containers by use of reliable container sealing, appropriate system flushing, and instrumentation interlocks that prevent overfilling the containers. The containers and shields are handled by a 907-ka (25-ton) capacity overhead bridge crane.

Compressible dry solid waste (e.g., contaminated clothing, wipe up toweling) is compacted into 55-gallon drums by a waste compactor.

x The filled drums are capped and placed in a storage area prior to

( ) shipment to a vaste burial site. The drums are handled with the aid of a manually operated device, such as a forklift fitted with a drum lifting attachment.

The solidification area is located on the ground floor of the waste disposal building. Wastes are packaged to allow for immediate 7 shipment after processing. Shipping containers may be stored in the solidification area and placed in shields, if necessary, until ready for shipment.

An average of sis 5.52-cubic meter (195-cubic foot) high integrity 7 resin containers will be processed per year.

Storage capacity and storage time are based solely on anticipated operational factors, including shipping delays. Holding capacity for radioactive decay is not required. since individual containers are shielded as necessary. However, based on routine storage of 2 weeks and minimum expected holdup and process times of 2 weeks, average decay time prior to shipping is 4 weeks.

7 Amendment 7 3.5-11 April 1984

MNPS-3 ER0LS Components of low activity, such as contaminated tools, can be packaged in available or specially designed shipping containers and stored, if necessary, in the solid waste building. However, it is expected that the latter type components will be shipped immediately.

The average processing rate for compressible waste is six drums per week. The estimated maximum processing rate is 30 drums per week.

One shipment would contain approximately 60 drums.

3.5.5 Process and Effluent Monitoring The radioactive gaseous waste relea.se points are the ventilation vent located on the turbine building and the Millstone 1 stack. The radioactive liquid waste discharge point is the circulating water discharge tunnel (Figure 2.1-3).

The Millstone 1 stack via supplementary leak collection and release system (SLCRS) is the discharge point for the reactor plant gaseous drains, chemical and volume control, reactor plant gaseous and aerated vents, condenser air removal and containment vacuum pumps system.

The ventilation vent and the Millstone 1 stack are continuously monitored. The process gas monitors in the individual gas streams alarm effluent discharges from the specific stream upon high activity signal.

The turbine building ventilation exhaust air is released from the turbine building roof vents. The effect of turbine building roof vent exhaust air on total offsite doses is negligible. Therefore, this release point is not monitored.

The liquid waste system discharge line is monitored upstream of the circulating water discharge tunnel. Upon high activity, this discharge is automatically terminated.

)

i

'd 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 gallons).

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 (N (50 gallons) of acid (66'Be) and 363 liters (96 gallons) of caustic

( ) (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 wastes contain approximately 3,230 mg/l of sulfate and 1,469 mg/l of sodium (Table 3.6-2). E. generation vastes from the caticn, anion, and mixed bed demineralizers are neutralized to a pH

'.,etween 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 poli.hing demineralizers maintain the condensate and feedwater system water quality. A total of eight mixed bed demineralizer., (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 regen 1 ration waste volume por polisher is Amendment 7 3.6-1 April 1984

MilPS-3 EROLS approximately 121,000 liters (32,000 gallons), of which 87,100 liter (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 7 radioactive, they will be treated as discussed in Section 3.5.2.

The waste neutralization system .or condensate polisher regeneration vastes is similar to that descrioed 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 frcm 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 ger.e ra to r . 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 pu;nps 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 bio'ouling control is not anticipated.

The service water system is a once-through cooling system which draws 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 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 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 Amendment 7 3.6-2 April 1984

MNPS-3 EROLS p)

V 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 t the quarry is maintained at a maximumoforlessthan0.25 ppm.l291*9 7 After mixing 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 below that which would occur through dilution alone. It is estimated that approximately 3,720 kg/yr (8,200 lb/yr) of chlorine (as Cla) 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 !!111 stone 3 plant areas. Oil and grease concentrations in the separata effluent are limited to 10 mg/1, average and 20 mg/1, maximum.

p Other Liquid Wastes

() 3.6.4 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 tha 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 maximuin 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 flasb 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 environtrent 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 waste neutralization sump or, if required, to the low level waste drain

tanks in the liquid radvaste system (section 3.5).

Amendment 7 3.6-3 April 1984

MHPS-3 EROLS 3.6.4.2 Low Level Waste Drain Tank Approximately 473,000 liters (125,000 gallons) of distillate are O discharged, on an annual basis, to the circulating water discharge tunnel frcm 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, boron demineralizer filter, and the effluent filters. Boron 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. T61s leakage is diluted by washing down for decontamination purposes and further diluted in the low level waste drain tanks tar other~ equipment and floor drainage. Small quantities, less_ than 1 ppia of lithium hydroxide used for pH control, could be released from this source.

3.6.4.3 Waste Test Tank Discharges The high levtl 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 dtmineralization 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 a11' 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. ._

The following are the maximum amounts of liquids handled by the waste evaporators annually O

Due to pump gland leakage and other equipment leakage, small quantities of hydrazine could be released into the circulating water.

The hydrazine reacts chemically with oxygen to form water and nitrogen. At high temperatures, hydrazine decomposes to form ammonia and nitrogen.

MNPS-3 EROLS C7 EFFLUENT vXICITY TESTING Routine effluent toxicity tests have been conducted on the discharge from Millstone Nuclear Power Station since 1981. Sheepshead minnow (Cyprinodon varigatus) and mysid shrimp (Mysidopsis bahia) have been tested under flow through conditions at 20 C 1 with undiluted effluent. Future testing will include the common indigenous species, winter flounder (Pseudopleuronectes americanus) and Atlantic silverside (Henidia menidia).

Ten partial life cycle tests from egg to juvenile stage have been conducted with sheepshead minnow. Tests consisted of three replicates / treatment (control and effluent) with ten individuals / replicate. No difference was found between treatments for egg viability, mortality, growth, or morphological anomalies.

Eight toxicity tests were conducted with mysid shrimp. These tests included several different procedures that were evaluated for long-term effluent toxicity assessment. The most efficient procedure consisted of a multiple generation exposure during a two .to three month period with three replicates / treatment. No differences between 7 control and effluent treatments were found in individual growth, brood size, and population growth rates.

Future effluent toxicity testing includes two common indigenous species, winter. founder and Atlantic silversides. Winter flounder

/"' testing is proposed for 1985 and will consist of testing yolk sac and I ,N) post-yolk sac. larvae.during their seasonal occurrence. Preliminary testing will be conducted under static conditions with renewal. Flow through testing will be evaluated for feasibility. Atlantic silverside- effluent testing is proposed for 1986. Testing will be conducted on the larval stage, and year round laboratory spawning may 1be possible. Parameters to be examined 'in winter flounder and Atlantic silverside effluent testing include mortality, growth, and morphologica,1 anomalies.
