2.0 ENVIRONMENTAL PROTECTION CONDITION 2.1 Thermal-2.1.1 Maximum AT Across Condenser Objective To Itait thermal stress to the aquatic ecosystem by limiting the maxi-mum AT across the condenser during operation.

Specification

a. The maximum differential temperature across the condenser shall not exceed 150F during normal operation with all four circulating water pumps in operation.

b. If one or two circulating water pumps are out of service at any given time, the maximum condenser AT shall not exceed 300F; and Specifica-l tion 2.1.2 of this Appendix shall be met.

! Monitoring Requiretaent The temperature differential across the cond'enser shall be monitored every hour utilizing the computer output of the condenser inlet and .

outlet temperature measurements. The range of these measurements shall

(.. be 0-1500F and their accuracy shall be 0.5%.

If the plant computer is inoperable, the condenser inlet and outlet temperatures shall be monitored-at least once per shift utilizing the condenser temperature recorder with a 0-1500F range and 0.5% accuracy.

Bases i

Maximum AT's of 150F with 4 circulating water pumps operating (s1700 cfs flow) and 300F with 2 circulating water pumps operating will insure that the limits of the applicable water quality criteria will not be exceeded.

The difference in temperature readings of the RTD's at the inlet and outlet of the condensers provides that AT across the condensers.

Specification 2.1.1.b allows maintenance to be performed on circulating water pumps when the Dardanelle Reservoir ambient temperature is such  ;

that Specification 2.1.2 will not be exceeded. Hydraulic model studies l have shown that a 300F AT at 850 cfs circulating waterflow will not result in adverse' changes in the Dardanelle Reservoir isotherms when {

compared to the isotherms resulting from a 150F AT at 1700 cfs except on the surface of the discharge embayment.

(

Revision 1 1 September 17, 1973

I q 2.1.2 Maximum Discharge Temperature L' ,

objective To limit themal stress to the aquatic t 'osystem by limiting the plants, maximum discharge water temperature.

Specification The condenser discharge' water temperature shall not exceed 1050F for more than two consecutive hours. If the discharge water temperature exceeds 1050F for two hours, an investigation of the situation will be undertaken and corrective action shall be taken to maintain the discharge water 1 temperature at 1050F or less. One such corrective action would be a re-duction in the plant power level unless there is an emergency need for the lost power. This emergency need would exist when a reduction in power would mean cutting off firm customers. If monitoring (see below) indicates that the temperature at the mouth of the discharge embayment is < 105 F, the plant load will not be reduced. ,

Monitoring Requirements Condenser discharge water temperature shall be monitored every hour utilizing the average of the computer output of the condenser discharge RTD readings.

The RTD's have a 0-1500F range and an accuracy of 0.5%.

( If the plant computer is inoperable, the condenser discharge water temper-ature shall be monitored at least once per shift utilizing the condenser temperature recorder with a 0-1500F range and 0.5% accuracy.

If the condenser discharge water temperature exceeds 1050F, plant personnel will be dispatched to the mouth of the discharge embayment to monitor i the exit temperature from the embayment to determine that it was <1050F, Monitoring of the embayment will continue once per shift as long Es the condenser outlet temperature remains at 1050F.

Bases The 1050F maximum discharge water temperature limit is set to assure that the Dardanelle Reservoir temperature does not exceed 950F as established by the applicable water quality criteria. The use of the condenser dis-charge RTD's provides the circulating water discharge temperature prior to mixing with the Dardanelle Reservoir water.

No credit was taken in the analyses and models of the circulating water system for heat exchange within the discharge embayment even though it is expected that the water temperature will be reduced in the embayment. 1 Thus, the average temperature should be <1050F even when the ter6perature at the condenser discharge is greater.

()

Revision 1 September 17, 1973

(]) 2.1.3 Maximum BTU /hr Not applicable.

2.1.4 Rate of Change of Discharge Temperature Objective To avoid thermal stress to the aquatic ecosystem due to sudden changes in water temperature.

, Specification In the event of a planned shutdown during the period November through April, the reactor power level shall be reduced to 0% at a rate such that the decrease in the condenser circulating water discharge temperature shall be <50F/hr in order to avoid any adverse thermal impact on the aquatic environment in the discharge embayment. As the reduction in power level is made and when feasible, the number of operating. circulating water pumps will be reduced so as to limit the rate of decrease of the water temperature in the discharge embayment.

This limitation may be exceeded for brief periods as necessary to protect plant equipmen't and for certain safeguard operations which cannot be

. limited or negated by plant operation. These' safeguard operations include

( -

. automatic plant trips and compliance with safety-related technical speci-fications.

This technical specification only applies to the first two years of plant operation (i.e., the first # ul cycle).

1 Monitoring Requirement

. Condenser discharge water temperature will be monitored every hour during the power reduction utilizing the average of the computer output of the condenser discharge RTD readings. The RTD's have a 0-1500F range and an accuracy of 0.5%.

If the plant computer is inoperable, the condenser discharge water tem-perature shall be monitored at least once per hour during the power reduction utilizing the condenser temperature recorder which has a 0-1500 F range and a 0.5% accuracy.

The aquatic environment of the discharge emba'yment will be watched during and immediately after planned shutdowns in order to detect any adverse environmental impacts on the embayment, which might occur.

Bases There has been no incidence of adverse environmental impact a'ssociated 1

.(~ , with any operating APGL power plant. There is also a lack of data or v

Revision 1 September 17, 1973

evidence which would support a limiting rate of change of temperature

{~5 for the specific species that might inhabit the discharge embayment.

In view of this, a conservative rate of change,150/hr, is specified.

It is also conservative because the actual rate of change of the dis-charge embayment will be slower than the rate of change of the circulating water system. A reduction in circulating water flow will further de-crease the rate of change of temperature in the discharge embayment. 1 If after a few planned shutdowns at the specified rate, there is no detectable adverse effect on the discharge embayment environment, then future planned shutdowns will be conducted at slightly higher rates with the appropriate monitoring until it is established that there is no adverse environmental impact associated with plant shutdowns, no matter what the rate might be. If the opposite occurs and there is some adverse environmental impact, the.n future planned shutdowns will be conducted at slightly slower rates until an acceptable shutdown rate is d ,termined.

(. 2.3 Chemical Obj ective - (General)

To protect.the local biota from lethal and sublethal effects of chemical discharges. To_ assure that the most sensitive use of the receiving medium by human populations is protected. To minimize degradation of the quality of the receiving medium.

Specification (General)

All plant chemical discharges except that from the plant sanitary system shall be diluted by the plant circulating water during release to assure that the stated objective can be achieved.

2.3.1 Blocides Specification

a.. Chlorine (Circulating Water System) ,

. Chlorination of ' condenser cooling water shall be intermittent (1 to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> each day or as may be necessary) . The concen'-

i tration _of free available chlorine residual (in the form of molecular chlorine, hypochlorous acid, and hypochlorite ion)

(~, measured at the condenser outlet shall be limited to a maximum l1 L of 1 mg/1. Total available chlorine residual in the plant effluent shall be less than 0.1 mg/1.

b. Chlorine (Sanitary Waste System) -

The hypochlorinator of the sewage-treatment system shall be maintained so that the effluent free available chlorine residual ,

shall not be greater than 0.1 mg/l at point of discharge to embayment.

Monitoring Requirement.

>\

a. Chlorine (Circulating Water System) i Total stailable chlorine residual in the discharge canal shall be measured twice weekly during periods of chlorination. Analyses will be made according to Table 2-1.

b. Chlorine (Sanitary Waste System -

The sewage treatment effluent shall be checked monthly to ensure that the total available chlorine residual is not greater than 0.1 mg/l at point of discharge to embayment. Analysis will be made accordicg to Table 2-1.

O Revision 1 September 17, 1973

Bases .

The once-through circulating water flow taken from the I.;inois' Bayou arm of the Dardanelle Reservoir will pass through the turbine condenser and will be discharged into an 80-acre embayment of the Reservoir.

Analysis of the chlorine demand of the Arkansas River water (i.e., the amount of chlorine required to oxidize substances in the water which reduce free chlorine) range from 2 to 4 mg/l for a contact time of 10 minutes. Reaction of chlorine with the untreated dilution water during the 4 to 5 minutes required for the flow to reach the embayment should reduce the concentration of total available chlorine residual below 0.1 mg/l in the effluent. It is estimated that Unit I chlorine usage

, will be. 330,000 lbs/ year.

2.3.2 Corrosion Inhibitors Specification There shall be no discharge of sodium nitrite to the plant discharge.

Monitoring Requirement The closed cooling water system of the plant shall be sampled weekly to ascertain whether sodium nitrite leakage from these systems has

. occurred.. .

' ~

Since sodium nitrite is subject to biodegradation, the test for nitrite nitrogen by Method 134 of Standard Methods will not conclusively e tablish whether leakage has occurred. Specific conductance will also 1 be measured using Method 154 of Standard Methods. If nitrite nitrogen drops and specific conductance remains constant, no leakage will be presumed. If both nitrite and conductivity are lower than the previous weekly test, immediate samples of discharge canal will be taken and a report made according to Specification 5.6.

Bases The closed cooling water systems are treated with sodium nitrite or sodium nitrite based inhibitors. Under normal condi.tions, there will be no discharge of the sodium nitrite inhibitor to the plant discharge.

Any leakage from these systems would normally be undetectable by sampling the discharge canal. Sampling of individual closed water systems will be utilized for leak detection. Some inhibitor will be consumed in the protecting of the closed water systems. It is estimated that annual usage after initial charging of all systems will be .',500 lbs/ year.

2.3.3 Suspended and Total Dissolved Solids

({}

Specification Both the conductivity and the turbidity'of the plant effluent in dis-charge canal shall not be more than 10% greater than that of the water in the intake canal.

Monitoring Requirement The turbidity and conductivity of water in the intake and discharge canals shall be determined weekly. Analyses shall be made according to Table 2-1.

Bases The plant is not expected to significantly contribute to suspended or 1 total dissolved solids. Turbidity and conductivity are accepted methods for determining these two parameters. A 10% increcae resulting from plant effluents will be considered significant.

2.3.4 pH Specification

(~ The pH of all discharges to the Dardanelle Reservoir shall be between

,- 6.0 and 9.0. No single unit of discharge shall change the discharge canal water more than 0.5 pH unit. -

Monitoring, Requirement -

The pH of the intake and discharge water shall be determined weekly.

Analysis shall be made according to Table 2-1, 2.3.5 Chemicals Which Affect Water Quality Specification All chemical releases shall be maintained to be less than those con-centrations permitted by the Arkansas Department of Pollution Control and Ecology. See Table.2-3.

Monitoring Requirement 1

Monitoring of the water in the intake and discharge canal will be done by weekly sampling and analysis for conductivity, chloride, hardness, phosphate, sulfate, turbidity, ammonia, iron, manganese, copper, silica, boron, hydrazine and pH. Analyses will be made according to Table 2-1.

If, after the concentrations present in the intake canal are subtracted from those present in the discharge canal, the concentration of any of Revision 1 September 17, 1973

the chemical parameters listed in this specification equal or exceed

/

the concentrations listed above, or those listed in Specification 4.1.1, a report will be made in accordance with Specification 5.6 of this Appendix B.

1 Bases Concentrations will be limited to meet requirements of the regulatory agencies concerned. Table 3-1 lists concentrations of chemicals ex-pected to be discharged and their concentrations now present in the lake water.

a 2.4 Radioactive Discharge o~ Objective To define the limits and conditions for the controlled release of radio-active effluents to the environs to ensure that these releases are as low as practicable. These releases should not result in radiation ex-posures in unrestricted areas greater than a few percent of naturci background exposure. The release rate for all effluent discharges should be within the. limits specified in 10 CFR Part 20.

To assure that the release of radioactive material to unrestricted areas meets the as-low-as-practicable concept, the following objectives apply:

For liquid wastes:

a.

The annual total quantity of radioactive materials in liquid waste,-

excluding tritium and dissolved gases, should not exceed 5 curies; 4

b.

The annual average- concentration of radioactive materials in liquid 4 waste upon release from the Restricted Area, excluding tritium and dissolved noble gases, shall not exceed 2 x 10-8 pCi/ml;-

c. The annual average concentration of tritium in liquid waste upon release and, from the '.estricted Area, shall not exceed 3 x 10-3 pCi/ml;

( d.

For gaseous wastes:

a. __

Averaged over a yearly interval, the release rate of noble gases and other radioactive isotopes, except I-131 and particulate radio-isotopes with half-lives greater than eight days, discharged from the plant should result in a dose rate at the site boundary of less than 10 mrem to the whole body or any organ of an individual.

b. Averaged over a yearly interval, the release rate of I-131 and other ,

particulate radio-isotopes with half lives longer than eight days discharged from the plant should result in a dose in the unrestricted area of less than 15 mrem by breathing or to the thyroid of a child

.through the grass-cow-milk chain.

2.4.1 Liquid Discharge Specification

1. The rate of release of radioactive materials in liquid waste from

e. the plant shall be controlled such that the instantaneous

(

Revision 1 September 17, 1973

4 concentrations of radioactivity in liquid waste, upon release from

() .

the Restricted Area, do not exceed the values listed in 10 CFR 20, Appendix B, Table II, Column 2.

2. If the release of radioactive materials in liquid effluents, when averaged over a calendar quarter, exceeds 2.5 curies, the Licensee shall:

a. hhke an investigation to identify the causes for such release rates;

b. Define and initiate a program of action to reduce such release rates to the design levels; and,

c. Notify the Director, Directorate of Licensing within 30 days, identifying the causes and describing the proposed progrma of action to reduce such release rates.

3. The release rate of radioactive liquid effluents', excluding trit'ium and dissolved gases, shall not exceed 10 curies during any calendar quarter.

4. During release of liquid radioactive waste, the following conditions shall be met:

a. At least two (2) condenser circulating water pumps shall be

(~ , in operation to provide a minimum dilution flow of approxi-

- mately 383,000 gpm in the discharge canal for the liquid .

waste effluent; .

b. The effluent control monitor shall be set to alarm and auto-matica11y close the waste discharge valve such that the requirements of Specification 2.4.1 are met; and,

c. The gross liquid waste activity and flow rate shall be con-tinuously monitored and recorded during release. If this requirement cannot be met,' continued release of liquid effluents shall be permitted only during the succeeding 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> provided that during this 48-hour period, two inde-pendent samples of each tank shall be analyzed and two station personnel shall independently check valving prior to the discharge.

'S. The equipment installed in the liquid radioactive waste system shall be maintained and operated to process all liquids prior to their discharge.when it appears that the projected cumulative discharge r&te excluding tritium and dissolved noble gases, released during any calendar quarter will exceed 1.25 curies.

k) .

Revision 1 September 17, 1973 12 -

L -

p# 6. The maximum activity to be contained in one liquid radwaste tank that can be discharged directly to the environs (Treated Waste Monitor and Filtered Waste Monitor Tanks only), shall not exceed 10 curies.

Monitoring Requirements

1. Facility records shall be maintained of the radioactive concentrations and volume before dilution of each batch of liquid effluent released, and of the average dilution flow and length of time over which each discharge occurred.

2. Prior to release of each batch of liquid effluent, a sample shall be taken from that batch and analyzed in accordance with Table 2-2 to demonstrate compliance with Specification 2.4.1.

3. Radioactive liquid waste sampling and activity analysis shall be performed in accordance with Table 2-2. -

4. The liquid effluent radiation monitors shall be calibrated at least quarterly by means of a known radioactive source. Each monitor shall be tested monthly andL checked daily when discharging. [1

5. The performance of automatic isolation valves and discharge tank selection valves shall be checked annually.

, Bases L'^J Releases of radioactivity in liquid wastes within the design objective levels provide reasonable assurance that the resulting annual exposure from liquid wastes to the whole body or any organ of an individual will ,

not exceed 5 mrem per year. At the same time the Licensee is permitted the flexibility of operation, compatible with considerations of health and safety, to assure that the public is provided a dependable source of power under unusual operating conditions which may temporarily result in releases higher than the design objective levels but still within the concentration limits specified in 10 CFR 20. It is expected that using this operational flexibility under unusual operating conditions, the Licensee shall exert every effort to keep levels of radioactive materials as low as practicable and that annual releases will not exceed ,

a small fraction of the annual average concentration limits specified in 10 CFR 20.

2.4.2 Gaseous Discharge Specification

1. .When the release rate of radioactive materials in gaseous wastes, averaged over a calendar quarter exceeds 4% of 2.4.2.3.a or 2% of l1 2.4.2.3.b, the Licensee shall notify the Director, Directorate of es O

Revision 1 September 17, 1973

Licensing within 30 days, identifying the causes of the excessive h>

activity and describing the proposed program of action to reduce )

such releases to design objective levels. l l

2. The maximum activity to be contained in one Waste Gas Decay Tank '

{',

greater than eight days released to the environs,as part of airborne effluents, shall not exceed 0.96 pCi/sec. l1 j

4. a. The release rate of gross gaseous, activity shall not excemf 16% of the values specified in 2.4.2.3.a when averaged over a calendar quarter.

b. The release rate of I-131 and particulates with half-lives greater than eight days shall not exceed 4% of the values 1 specified in 2.4.2.3.b when averaged over a calendar quarter.

5. During release of radioactive gaseous wastes from the gaseous waste discharge header to the plant ventilation exhaust plenum, the following conditions shall be met:

a. The waste gases and particulates shall be passed through high efficiency particulate (HEPA) and charcoal filters pro-vided in the discharge line (except as noted in Specification 2.4.2.6 below);

7. Radioactive gaseous wastes collected in the gas decay tanks shall '

be held up for a minimum equivalent decay time of 45 days, except  !

when the estimated activity concentration of each identified 1 radioisotope at the site boundary is less than 1% of the MPC specified in 10 CFR Part 20, Appendix B, Table II.

8. Purging of the Reactor Building shall be- governed by the foIIowing conditions:

i

a. Reactor Building purge shall be through the high efficiency

. particulate filters and charcoal filters until the activity

( concentration is below the occupations 1 limit inside the Reactor Building, at which time bypass may be initiated; and 4

. b. Reactor Building purge shall be through the high efficiency

. particulate filters and charcoal filters whenever. irradiated i fuel is being handled or any objects are being handled over

irradiated fuel in the Reactor Building. .

9. Gases discharged through therunit vent shall be continuously

, monitored and recorded for gross (8,y) activity.

i Whenever these monitors are inoperable, appropriate grab samples 1 l shall be taken and analyzed daily.

~

f ' Monitoring Requirement

1. Radio. active gaseous waste sampling and analysis shall be performed j in accordance with Table 2-2.

2.; All waste gas monitors shall be calibrated at least quarterly by means of a known radioactive source. Each monitor shall be tested 1

. at least. monthly and checked at.least daily when discharging.

t .

G Revision 1 September 17, 1973

3. During power operation, the condenser vacuum pump discharge shall

(]) be continuously monitored for gross radiogas activity. The monitor,shall not be inoperable for more than 7 days. Whenever this monitor is inoperable,' grab samples shall be taken and analy:cd for gross radioactivity daily.

4. Records shall be maintained and reports of the sampling and analysis results shall be submitted in accordance with Specification 5.6.

5. The Waste Gas Decay Tank effluent monitor shall be tested prior to any release of radioactive gas from a decay tank and shall be cali-brated at refueling intervals.

Bases: ,

It is expected that the releases of radioactive materials and gaseous wastes will be kept within the design objective levels and will not exceed on an instantaneous basis the dose rate limits specified in 10 CFR 20.

These levels provide reasonable assurance that the resulting annual exposure from noble gases to the whole body or any organ of an indivi-dual will not exceed 10 mrem per year. At the same time, the Licensee is permitted the flexibility of operation, compatible with considerations of health and safety, to assure that the public is provided a dependable

{' source of power under unusual operating conditions which may temporarily result in releases higher than the design objective levels but still within the concentration limits specified in 10 CFR 20. It is expected that using this operational ficxibility under unusual operating condi-tions, the Licensee- shall exert every effort to keep levels of radioactive materials and gaseous wastes as low as practicable and that annual re-Icases will not exceed a small fraction of the annual average concentration limits specified in 10 CFR 20. These efforts shall include consideration

~

of meteorological conditions during releases.

MINIMUM SAMPLING FREQUENCY

.(1)' When radioactivity level is greater than 10 percent of the limits of Safety Specification 3.1.4, the

. sampling frequency shall be increased to a minimum of once. each day.

(2) E determination will be started when gross beta-gamma ' activity analysis indicates greater than 10 pCi/ml and.will be redetermined each 10 pCi/ml increase in gross beta-gamma activity analysis. A radiochemical analysis for this purpose shall consist of a quantitative measurement of 95% of radionuclides in reactor coolant with half lives of 30 minutes. This is expected to consist of gamma isotopic analysis of dissolved

.and gaseous activities, radiochemical analysis for Sr 89, 90, and tritium analysis.

(3) When. gross activity increases by a factor of two above background, an iodine analysis will be made and performed thereafter when the gross beta-gamma activity increases by 10 percent.

(4) When activity level exceeds' 1O percent of the limits of Specification 2.4, the sampling frequency sh,all be increased to a minimum of once each day. When the gross activity release rate exceeds one percent of ,

, maximum release rate and the average gross activity release rate increases by 50 percent over the previous g day, an analysis shall be perforu d for iodines and particulates.

(5)' A proportional sample is one in which the quantity of liquid sampled is proportional to the quantity.of.

liquid waste discharged from the plant.

(6) The detectability limits for activity analysis are based on the technical feasibility and on the potential significance in the environment of the quantities released. For some nuclides, lower detection limits may be readily achievable and when nuclides are measured below the stated limits, they should also be reported.

(7) For certain mixtures of gamma emitters, it may not be possible to measure radionuclides in concentrations .

near their sensitivity limits when other nuclides are present in the sample in much greater concentrations.

Under these circumstances, it will be more appropriate to calculate the concentration of such radionuclides using observed ratios with those radionuclides which are measurable.

(8) Analyses shall also be performed following each refueling, startup or similar operational occurrence which could alter the mixture of radionuclides.

,h 3.0 DESIGN FEATURE $ AND OPERATING PRACTICES 3.1 Intake System .

A velocity of 1.5 fps will occur in the intake canal from Illinois Bayou.

Velocities greater than 2.0 fps are expected to exist at the intake screens. Therefore, loss of fish due to impingement against the intake screens is expected to occur. Monitoring specified in 4.1.2.2 shall permit a quantitative assessment of the impact and an early identifica-tion of the need, if any, for corrective action or modifications to the intake system.

3.2 Discharge System There are no design features or operating practices pertaining to the discharge system not covered in Section 2 which would have a significant adverse effect on the environmental impact if changed.

3.3 Chemical Usage Table 3-1 lists the estimated chemical usage and expected discharges.

If actual uscae exceeds estimated usage by more than a factor of 3.0, environmental effects of such chemical usage shall be reevaluated and shall be reported in accordance with Specification S.6.2.

(] 3.4 Plant Shutdown The rate of change of the condenser discharge water tempera?.ure is limited by Specification 2.1.4 to protect aquatic organisms from thermal shock as a result of plant shutdown.

3.5 Land Management Transmission line rights-of-way have low growing species of cedar, sumac, oak and shrubs as a screen and to assist with erosion control.

Planting of-grass and clover shall be carried out to further prevent erosion. ' Further plantings of game food and cover shall be made in cooperation with landowners and the Arkansas Game and Fish Commission.

No herbicides shall be used for land management on transmission line rights-of-way.

The grounds in the immediate vicinity of the plant building shall be landscaped. Remaining portions of the plant site shall be allowed to remain in their present wild state with the exception of the area on which the visitors center will be located. This area is located approx- 1 imately 0.7 mile northeast of the Reactor Building on a hill overlooking the plant.

l Q. 4.0 ENVIRONMENTAL SURVEILLANCE The surveillance program provides a thorough examination of the aquatic ecosystem of Lake Dardanelle in the vicinity of the plant as well as providing information on air, precipitation, ground water, soil, vege-tation and milk by radiological analysis of samples in the area of the plant.

Since the aquatic ecosystem is the most likely to be affected both chemically and radiologically by plant operation, more emphasis has 1 been placed on its surveillance. The waters of Lake Dardanelle are subjected to frequent chemical and radiological analyses. Organisms that live in the Lake are studied biologically and subjected to radio-logical testing. Studies are also made on the effects of impingement and entrainment of organisms in the cooling water system. Provision is also made for temperature monitoring and controlling the rate of change in water temperature (Specification 2.1.4).

~

Results of the program, including the reports submitted in Specification S.6 will be reviewed as.specified in 5.3. .

4.1 Ecological Surveillance 4.1.1 Abiotic

a. Aquatic

{

(1) Chlorine Objective:

To determine the levels of chlorine concentration in station effluent water.

Specification:

(a) Samples shall be taken twice weekly at the outlet of the discharge canal during chlorination periods and analyzed for chlorine and chloramines accord-ing to Method 114F of " Standard Methods."

)

(b) If total chlorine concentration in the discharge canal exceeds 0.1 mg/1, chlorine feed shall be ,

reduced to a rate that results in a concentration in the discharge canal of less than 0.1 mg/l chlorine, and immediate sampling and chlorine analyses will begin at Points 1, 18, 5, and 9 1 (shown on Figure 4-3).

O Revision 1 September 17, 1973

Reporting Requirements:

(]}

If total available chlorine residual is found to be 0.1 mg/l or above at any of the Points 1,18, 5, or 9 (shown on Figure 4-3), a report shall be made ac-cording to Specification 5.6.2.

1 Bases:

Chlorination of circulating cooling water shall be intermittent. Only one-half of the condenser shall be chlorinated per chlorination period. This arrange-ment will provide both dilution and additional chlorine demand to prevent excessive chlorine concentrations.

(2) Corrosion Inhibitors Objective:

Tb insure that the sodium nitrite based corrosion in-hibitor used in the plant closed cooling water systems does not enter the Reservoir in such concentrations as to be harmful to aquatic biota.

Specifications:

{ 'T (a) Samples shall be taken weekly from the intake and discharge canals and shall be analyzed for nitrite nitrogen according to Method 134 of " Standard Methods." Weekly samples taken near or upstream of Point 20 (shown on Figure 4-3) coincident with y sampling of intake and closed cooling water samples will also be analyzed for nitrite to determine if recirculation is occurring.

(b) Samples of the closed cooling water system shall be analyzed for inhibitor weekly according to the manufacturer's instructions to determine leakage from this system.

Reporting Requirements:

If discharge canal samples show a concentration of 0.005 mg/l of nitrite nitrogen or more after subtracting the concentration of nitrite nitrogen found in the 1 intake canal or Point 20 samples (whichever is smaller),

a report will be made in accordance with Specification 5.6.

O Revision 1 September 17, 1973 i

Bases:

Under normal conditions, no sodium nitrite based corrosion inhibitor will be discharged to the Reservoir. Any abnormal leakage should be detected either in the discharge canal or by inhibitor analysis in the cooling system.

Any leakage of sodium nitrite from the closed cooling water system will most probably find its way to the discharge canal. By sampling the intake canal and Point 20, a determination can be made of any nitrite 1 present in the lake water from sources other than plant operation. Specification 2.3.2 requires that no sodium nitrite be discharged. 0.005 mg/l is the detection limit for the nitrite nitrogen test.

(3) Dissolved Oxygen:

~ ~ ~

Objective:

To determine levels of dissolved oxygen concentration in the Reservoir water and the effects of station effluents thereon.

(. Specifications:

(a) Dissolved oxygen analysis shall be made at all sample points shown in Figure 4-3 on a monthly basisi See Table 4-6r !1 (b) Analyses shall be mada at the one and two-foot

-- depths and at five-foot -intervals-thereafter to the bottom.

(c) Analysis shall be made using a polarographic membrane electrode with Yellow Springs Instruments Model 54 or equivalent. The instrument shall be calibrated just prior to and immediately following I

the analyses described in (a) above 'according to Method 218F of " Standard Methods."

Reporting Requirements:,

If dissolved oxygen is found to be less than 5 mg/1, a report shall be made according to Specification 5.6.

1. P Bases:

Monthly analyses of dissolved oxygen will provide information on changes in concentration caused by naturally occurring seasonal changes as well as any changes brought about by plant operation.

Sampling locations were chosen to provide information about the intake and discharge of station cooling water and its effect on dissolved oxygen in the Reservoir water.

Arkansas Department of Pollution Control and Ecology Regulations require that dissolved oxygen not be less than 5 mg/l except when periodic lower values are of 1 natural origin and therefore beyond the control of the water user.

a. Aquatic (1) General Ecological Survey Objective:

The purpose of this survey is to provide information on the compatibility of Arkansas Nuclear One (ANO) with the planktonic, nektonic, and benthic populations of the Dardanelle Reservoir.

Preoperational monitoring studies have been conducted since 1968, approximately five years prior to operation of Unit 1. These studies served as a basis for develop-ment of the operational monitoring program described herein. The operational monitoring shall begin with the operation of Unit 1 and shall continue for five years after Unit 2 goes into operation. The effects .

of. plant operation shall be determined by comparison of ecological parameters studied in the preoperational program. .

I f) Fish Cage Survey Cages containing mussels shall be placed at sample stations shown on Table 4.3 and marked for recovery. Mussel samples shall be re-covered semiannually and retained for radio-

, logical testing.

Reporting Requirements:

This survey shall be carried out by:

(a) The University of Arkansas at Little Rock (UALR)

,_ (b) Arkansas Polytechnic College, Russellville, Arkansas (c) Arkansas Power 6 Light Company.

. Annual meetings shall be held to discuss the results of the survey and, if ne,cessary for better data, make modifications in the survey.

Reports shall be provided to APSL at least every six month: and copies shall be distributed to the Arkansas Department of Pollution Control and Ecology, UALR, U. S.

Corps of Engineers, U. S. Department of Interior (Bureau of Sports Fisheries and h'ildlife), Arkansas Game and

.i Fish Commission, U. S. Environmental Protection Agency, U. S. Atomic Energy Commission, the Arkansas State De-partment of Health, (Bureau of Environmental Health Services).

Bases:

The purpose of the proposed programs is to monitor possible influences by Arkansas Nuclear One on aquatic life in Lake Dardanelle. The programs are set up so as to sample various levels in the food chain to detect 1 any abnormalities in number, distributic1, size, or physical characteristics of the organisms.

O- .

Revision 1 September 17, 1973

l i

h Sample stations were selected at various points in the area around the site so that data could be co!1ected and a range of plant influence could be determined. By selecting points at the intake and discharge coves, direct changes in the lake water can be observed. The points upstream and in the Illinois Bayou were selected to monitor upstream aquatic life and plant influence.

Stations were selected at scattered locations throughout the river channel so that ANO effects could be surveyed.

Frequencies of sampling were chosen to obtain a trend of aquatic life in the area. Most fish surveys are set up to be conducted in the summer because the fish are more plentiful at this time of year. It is felt that more frequent sampling of the organisms would produce 1 l repetitive data. However, less frequent sampling might l yield erratic data from which no trend could be detected. l l

The data wif1 be evaluated in relation to preoperational

. data obtained by AP6L, UALR, Ark. Tech., and various i

governmental agencies. By comparing preoperational data with postoperational data, changes in the environment

. can be detected. It is felt that in this way effects on the aquatic life by ANO can be monitored and controlled.

i Impingement of Organisms

{ (2) j Objective:

Theobjectiveistomonito[thosefishimpingedonthe ~~

intake screens to permit a quantitative accessment of -

impingement impacts. If these impacts are significant, appropriate state and federal agencies responsible for ,

, fisheries shall be consulted and the necessary modifi- )

cations to the intake system shall be implemented to  ;

satisfactorily reduce these impacts.

-l Specification:

All fish trapped on the intake screens are sluiced to I 1 a collection basket where they are identified, counted and weighed initially on a daily bases. Weekly tabu-lations of this data will be made.

i After the data is taken, the fish will be dumped into the trash grinder and discharged back into the outfall. 1 Should this method of disposal cause a condition of

! pollution in the discharge embayment of the Reservoir, alternate methods such as land fill disposal would be used.

A No firm regulations can be established for what a V condition of pollution is because it is dependent upon all of the environmental factors present at that time. If the discharge embayment should become a nuisance to the inhabitants of the area or to the i fishermen, or if the Biochemical Oxygen Demand (BOD) should increase abnormally or Dissolved Oxygen counts (DO) should be drastically reduced, then the proper governmental agencies will be notified to make further surveys to determine if the situation is a condition of pollution. ,

Reporting Requirements:

Weekly tabulations of data on species, quantity and I weight of fish collected on intake screens will be reported on a semiannual basis.

(3) Entrainment of Plankton, Eggs and Larval Forms Objective:

The purpose of the entrainment study is to determine the thermal and mechanical effects of the cooling water system on the various kinds and quantities of larvae, eggs, and plankton taken into the plant water system.

(s ,

Specification:

Biological samples (organisms) of bottom samples and water samples were taken at six-month intervals prior

. to plant operation and shall be taken at one-month intervals after operation at the intake and discharge locations. Pelagic larval fishes shall be sampled by trawling with a fish larval net also in the intake and discharge areas.

Reporting Requirements:

If.the samples taken indicate a significant detrimental effect on these organisms such as radically increased radioactivity or drastically reduced population and these factors can be traced to ANO, whether due to pressure changes, thermal shock, mechanical stress or blocide exposure, appropriate action shall be taken to 1 assure that these effects will not ultimately affect survival of the organism or its popu.ation. For addi-tional information on the monitoring of these organisms, see Specification 4.1.2.a.1, General Ecological Survey.

W O 4.2 Radio 1o,1ca1 environmenta1 soniterin, -

Objective:

To provide information on the radiological effects of station operation on the environment.

Specification:

An environmental radiological monitoring program will be carried out as defined in Tables 4-1 and 4-2 at locations defined in Figure 4-1 and Table 4-2. .

4.2.1 Air Samp11ng Continuous air sampling is performed at four locations onsite, two off- ,

site within a ten-mile radius of the plant, and one reference location.

Locations have been selected near site boundaries and in existing populated areas for evaluation of possible exposure to airborne particulate and halide radioactivity resulting from station operation. The collection devices for iodine will contain potassium iodide impregnated charcoal or equivalent, and will be constructed and operated so as to retain quanti-tative1y the iodine in the air passing through the device. Appropriate analyses of particulate filters and halide collection devices are per-formed on all. samples in accordance with accepted techniques-and nuclides

( of interest.

4.2 : Direct Radiation Ambient levels of direct external radiation are measured at the same ,

locations as air particulate. Measurements are made by exposing l Harshaw TLD 100 (LiF) and TLD 200 (CaF) thermoluminescent dosimeters  !

for periods of three months and six months, respectively.

4.2.3 Precipitation Sampling -

Precipitation sampling is carried out at four locationsi two onsite, l one within a ten-mile radius, and one reference location approximately 1 twenty miles southwest of the plant. Analyses are performed as given I in Table 4-1.

4.2.4 Lake Dardanelle Samples of lake water are taken monthly from the mouth of the discharge canal and at various points in the Reservoir as shown in Table 4-2 and Figure 4-1. Appropriate analyses are performed in accordance with accepted techniques and nuclides of interest as given in Table 4-1. The status of plant discharge operations will be recorded and correlations between discharge operations measured levels of radioactivity in the environment noted.

s b

Revision 1 September 17, 1975

{ 4.2.S Ground Water Sampling -

Samples are taken quarterly from one onsite well and two offsite wells within a five-mile radius of the plant. One of the offsite wells is a

! water supply well for the town of London. Locations of the wells are shown in Figure 4-1, and the analysis is performed as shown in Table 4-1.

4.2.6 Russellville City Water City water is sampled monthly at the system intake on the Illinois Bayou.

Samples are analyzed for gross alpha and be'ta, gamma emitting isotopes as shown in Table 4-1. Tritium and radiostrontium

• will be performed quarterly on composite samples.

4.2.7 Reservoir Bottom Sediments ,

Samples will be taken semiannually with a 9-inch by 9-inch Ekman Dredge et the same points as lake water samples are taken. Analyses and samples size are as shown in Table 4-1.

4 . 2. 8- Aquatic Biota Samples of fish, plankton, benthic organisms, and underwater plants as available, will be taken semiannually at or near the same points where bottom sediment samples are taken. Appropriate analyses of all samples are performed in accordance with accepted techniques and nuclides of interest as given in Table 4-1, 4.2 9 Fish Bone .

Samples of fish bone from the fall aquatic biota sampling period will be retained and analyzed for Strontium 89-90 each year.

4.2.10 Milk Sampling Samples of milk are collected monthly from the Kirkpatrick farm approxi-mately eight miles west-northwest, from the Sims farm 4.8 miles northwest of the plant and from the Arkansas Tech. Herd S miles east. Samples will be analyzed for Iodine-131, Strontium 89-90 and gamma emitting isotopes.

l The area within five .(S) miles of the plant will be surveyed for the locations of animals (cows, goats) producing milk for human consumption.

These locations will be included in the milk sampling program as soon as the necessary arrangements can be made. The sampling frequency for locations nearer than three (3) miles 'will be every two weeks during the grazing season and locations nearer than 1.5 miles will be sampled weekly during the grazing season. Each sample will be analyzed for I-131 ar.

in Table 4-1, and monthly composites will be analyzed for radiostrontium and gamma emitters.

• Radiostrontium analysis includes identification of Sr 89 and 90.

Revision 1 September 17, 1973

O-

- 4.2.11. Vegetation Sampling Grass and the leafy portions of other natural vegetation available at each of the air sampling stations will be collected three times per year (spring, summer, and fall) . Food crops and pasturage in the vicinity of the plant will also be collected as available at harvest time. Appropriate analyses of all samples are performed in accordance with accepted techniques and nuclides of interest as given in Table 4-1.

4.2.12 Soil Sampling ,

Soil samples are collected semiannually at the same locations as vegeta-tion samples and analyzed for gross alpha and gross beta and gamma emitting isotopes as described in Table 4-1. The Fall sample is also analyzed for Strontium 89-90.

Bases:

One of the limiting conditions for operation of Arkansas Nuclear One is restricting environmental effects due to plant operation in unrestricted

- areas surrounding the plant site to within limits specified in AEC Regulations 10 CFR - Parts 20, 50, and 100. This Radiological Monitoring Progran includes measurements made on the air, water, and land environ-ments to insure that these limits are observed.

C 6.0 SPECIAL SURVEILLANCE, RESEARCH, OR STUDY ACTIVITIES 6.1 Thermal plume mapping Objective To verify analytical and model studies of the thermal plume and to establish compliance with applicable water quality criteria under low-flow conditions in the Reservoir.

Program Specification A quasi-synoptic survey of the plant's thermal plume will be made by towing several' fast response temperature sensors over a pre-planned grid track. Temperatures at five depths will be sampled sequentially at frequent intervals and the data will be automati-cally recorded (digitally) for processing. Wire angle and boat position will be measured and recorded throughout the survey so -

that the absolute position in space of each recorded temperature can be of such density that computer contouring will be i sed for information display. .

This survey will be carried out once prior to plant operation to

~

7.s

( obtain background: temperature data. "When the plant has achieved full power operation, a series of 12 monthly surveys will be con-ducted to define the three dimensional aspects of the thermal dis-charge. Various flow conditions will occur during the year allowing i verification of compliance with applicable water quality criteria at several different- flow conditions. Each continuous underway field survey will result in several thousand discrete data points. This data will be processed by computer to provide contours of temperature for each measured depth. At the conclusion of the survey program, a final report will be prepared which will assess seasonal trends and correlate the measured temperatures and plume configurations with causative natural effects and plant operational data, s

p A (5 Reporting Requirements

u. -

The results of this survey shall be reported to the AEC upon the completion of the survey.

Bases This survey is necessary to establish compliance with applicable water quality criteria. It will be conducted by a consultant firm

~

competent in the measurement of thermal discharges from power plants.

This will insure that the survey data will be accurate and reliable in determining compliance with applicable water quality standards.

6.2 Fish Spawning Characteristics of Dardanelle Reservoir Objective A program has been undertaken to determine the characteristics of the Dardanelle Reservoir relative to fish spawning activities.

Program Specifications . .

This program relates to the fish spawning activities during the Spring of 1973 and shall determine the spawning fish populations and sizes in the intake canal, discharge embayment, and one ref-r- crenco area. -

\.

Samples ~ shall be taken by fish nets selected to provide optimum i spawning information. The positions for shore-line seining operations will be chosen in areas characteristic of fish spawning.

In addition, the pelagic larval fishes will be sampled by trawling with a' fish larval net. Major spawning areas will be determined by sampling several points in each area. Once the optimum sampling points'have been located, consistent sampling will be done to provide as much practical information as pessible.

Samples taken by net will be~ separated according to size, and reported by number under each size. Data will be prepared noting any signi-ficant changes or unusual conditions. At the time of this writing the progress has been completed and the results are being tabulated.

Reporting Requirements The results of this survey shall be reported to the AEC upon its completion.

Bases This survey will provide information relative to the peak spawning period and the relative abundance of these fishes. This in turn will

,. allow a more detailed evaluation of the data obtained from the opera '

(,) tional fish monitoring program.
