2.0 LIMITING CONDITIONS FOR OPERATION 2.1 THERMAL Objective (General)

To limit thermal stress to the aquatic ecosystem and control effluent cooling water temperature within prescribed limits which are consistent with applicable Federal and State regulations,in order to minimize adverse thermal effects.

J 2.1.1 Maximum AT Across condensers i

Objective To limit the maximum temperature rise across the cc denser during normal operation at all power levels.

Specification The temperature rise across the condenser shall not exceed 17.5'F for 7

a period of more than 3 consecutive hours or a maximum of 21*F unless 1 e V

there is an emergency need for power as defined in Section 1.

Monitoring Requirement The condenser temperature rise shall be monitored by detectors (RTD's 0-200 i l'F) located in the condenser inlet and outlet water boxes. The detector signal will be monitored by the control room computer. The AT will be alarmed at 17.5'F and at 21*F maximum.

If the RTD's or computer are inoperative'during power operation

~

above 80%, the condenser AT shall be determined every 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />s-

+ 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> utilizing local temperature indicators on each water box l.

(30-130 1 2*F).

. Bases l

When Unit 3.is operated at design capacity, the intake temperature should be elevated by a value AT-of 17.5'F.

When any one shell of the two twin-shelled surface steam cordensers is inoperative for maintenance or other reasons, the AT uill rise.

Each of the 4 condenser sections will require cleaning every 4 weeks, due to the buildup of marine growth or debris in the pipes and condensers.

During extreme climatic conditions, especially during tropical storms, sea. grass is uprooted from the Gulf of Mexico, requiring

.,--,,-e

---.-...,..,.-..,,v.e w,. -

2-2 temporary shutdown of a circulator to clean grass and other debris which has accumulated at the intake structure or inside the con-denser water boxes. This will cause a temporary increase in the AT across the condenser. Because of these conditions the AT of 17.5'F may be exceeded for a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> period with 21*F specified as a maximum limit. Monitoring by means of RTD's in the condenser inlet and outlet water boxes will provide reliable values of the AT across the condenser.

2.1.2 Maximum Discharge Temperature Objective To limit the macimum temperature of the condenser cooling water discharged from the plant to the environment during normal operation.

Specification The temperature of the condenser cooling water at the Point of Dis-charge shall not exceed 103*F for a period of more than 3 consecutive hours or a maximum of 106*F unless there is an emergency need for power as defined in Section 1.

Monitoring Requirement The temperature at the point of discharge shall be monitored once per hour during power operations of Unit 3 utilizing the automatic or manual address of thermistor buoy Station "E" of the Environmental Data Acquisition System. The temperature sensor system has a range of 30 - 110* and an accuracy of 1 0.2%.

If this buoy is inoperative, temperatures from other buoys (upstream and downstream) in the discharge canalshall be monitored. Once per hour during power operacions of Unit 3.

When the data acquisition system is inoperative the temperature at the point of discharge shall be estimated using operating and physical data in conjunction with curves generated by an empirical analysis of the Crystal River discharge canal variables.

l I

Bases lie effluent temperature limits during normal operations have been established to assure that the affected area within the receiving waters is minimized. Due to conditions as specified in Section 2.1.1 Bases, the condenser cooling water temperature of 103*F at the point of discharge may be exceeded for a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> period with 106*F specified as a maximum limit.

c 2-3 2.2 HYDRAULIC Not applicable.

2.3 CHEMICQ Objective (General)

To ensure that all chemical releases from the plant are controlled and diluted so as not to adversely affect public health or the natural environment and which are consistent with applicable State and local regulations.

2.3.1 Biocides Obj ective To limit the amount and concentration of total residual chlorine in the discharge.

Specification The concentration of total residual chlorine shall not exceed 1.8 ppm in an individual conden.ser outlet water box.

The frequency of chlorination shall not exceed 30 minutes per water box per shift and chlorination of each of the condenser circulating pipes and water boxes shall be staggered to prevent simultaneous treatment with chlorine.

Monitoring Requirement A continuous chlorine recorder with a' detection limit of 0.1 mg/ liter shall be observed once each day on days when chlorination is performed to verify that the total residual chlorine does not exceed 1.8 ppm in the 1.9 e idual condenser outlet water boxes. The continuous r

chlorine anal;ter shall be calibrated semi-annually.

When the chlorine analyzer and/or recorder ere inoperative, a sample shall be taken of each affected water box weekly (during chlorination) and analyzed.

Bases Residual chlorine has a potentially detrimental effect on the estuary.

The chlorine demand of the seawater at Crystal River has a range of 0.6 - 1.8 ppm. Only one of the four water boxes is chlorinated at a time. This results in water having a iaxinum chlorine residual of 1.8 ppm mixing with three equal volumes c f aater having a ninimum chlorine demand of 0.6 and the almost immadiate chemical reduction of the remaining chlorine within the Unit 3 discharge. As each L

1 l

l

e 2-4 water box is being chlorinated, a sample is taken from the outlet water box, analyzed for residual chlorine (free and combined), and the results are recorded on a circular recorder.

Samples are automatically changed by solenoid valves in accordance with the sequence of the chlorine generation system. This system provides a continuous record of chlorine residual in each outlet water box.

2.3.2

. corrosion Inhibitors No chromates shall be used.

2.3.3 Other chemicals which Affect Water Quality Chemical releases anticipated from the plant with the exception of chlorine-treatment of' the condenser cooling water are monitored as described in Section 3.1.6.

2.4 RADIOACTIVE EFFLUENTS Obj ective: To define the limits and conditions for the controlled release of radioactive materials in liquid and gaseous effluents to the environs to ensure that these releases are as low as practicabic. These releases should not result in radiation exposures in unrestricted areas grer er than a few percent of natural background exposures. The concentration of effluent discharges of radioactivities shall be within the limits specified in 10 CFR Part 20.

To ensure that the releases of radioactive material above back-ground to unrestricted areas be as low as practicable, the following design objectives apply:

~

~

Bases The release of radioactive materials in liquid waste effluents to unrestricted areas shall not exceed the concentration limits specified in 10 CFR Part 20 and should be as low as practicable in accordance with the requirements of 10 CFR Part 50.36a. These specifications provide reasonable assurance that the resulting annual dose to the total body or any organ of an individut.1 in an unrestricted area vill not exceed 5 mrem. At the same time, these specifications permit the flexibility of operation, compatible with con-siderations 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 Part 20.

It is expected that by using this operational flexibi ity under unusual operating

[

I conditicas, and exerting every effort to keep levels of radioactive material in liquid wastes as low as practicable, the annual releases will not exceed a small fraction of the concentration limits specified in 10 CFR Part 20.

i l

The design objectives have been developed based on operating experience l

taking into account a combination of variables including defective fuel, primary system leakage, primary to secondary s-stem leakage, and performance of the various waste treatment systems.

l s

9

o c.

2-8 A.

Specification 2.4.1.A requires the licensee to limit the concentration of radioactive materials in liquid waste affluents released from the site to levels specified in 10 CFR Part 20, Appendix B, Table II, Column 2, for un-restricted areas. This specification provides assurance that'no member of the general public will be exposed to liquid containing radioactive materials in excess of limits

, considered oermissible under the Commission's Regulations.

Specification 2.4.1.B and 2.4.1.C establish the upper limits for the release of radioactive materials in liquid effluents. The intent of these Specifications is to permit the licensee the flexibility of operation to assure that the public is provided a dependable source of power under i

unusual operating conditions which may temporarily result in releases higher than the levels normally achievable when the plant and the liquid waste treatment systems are i

functioning as designed. Releases of up to these levels will result in concentrations of radioactive material in liquid waste effluents at small percentages of the limits specified in 10 CFR Part 20.

C.

Specifications 2.4*l.b and 2.4.1.E require that suitable equipment to control and monitor the releases of radioactive materials in liquid wastes are operating during any period these releases are taking place consistent with the require-ments of 10 CFR Part 50, Appendix A, Design Criterion 64.

D.

Specification 2.4.1.F requires that the licensee maintain and operate the equipment install &d in the liquid waste systems to reduce the release of radioactive materials in liquid effluents to as low as practicable consistent with the. requirements of 10 CFR Part 50.36a. Normal use and maintenance of installed equipment in the liquid waste system provides reasonable. assurance that the quantity released will not exceed the design objective.

In order to keep releases of radioactive materials as low as practicable, the specification requires' operation of equipment whenever it appears that the projected cumulative I

discharge rate will exceed one-fourth of this design ob-(

jective annual quantity during any calendar quarter.

m

,s 2-9 E..

Specification 2.4.1. G limits the amount of radioactive material that could be inadvertently released to the environment to an amount that will not exceed the Technical Specification limit.

F.

In addition to limiting conditions for operation listed under Specification 2.4.1.B and 2.4.1.C, the reporting requirements of Specification 2.4.1.H delineate that the licensee shall identify the cause whenever the cumu-lative release of radioactive materials in liquid waste effluents exceeds one-half the design objective annual quantity during any calendar quarter and describe the proposed program of action to reduce such releases to design objective levels on timely basis. This report must be filed within 30 days following the calendar quarter in which the release occurred.

G.

The sampling and monitoring requirements provide assurance that radioactive materials in liquid wastes are properly controlled and monitored in conformance with the require-ments of Design Criteria 60 an 64.

These requirements provide the data for the licensee and the Commission to evaluate the plant's performance relative to radioactive liquid wastes released to the environment. Reports on the quantities of radioactive materials released in liquid waste effluents are furnished to the Commission according to Section 4.6.1.B in conformance with Regulatory Guide 1.21.

On the basis of such reports and any additional information the Commission may from time to time require the licensee to take such action as the Commission deems a.propriate.

Bases: The release of radioactive materials in gaseous waste effluents to unrestricted areas shall not exceed the concentration limits specified in 10 CFR Part 26 and should be as low as practical in accordance with the requirements of 10 CFR Part 50.36a. These specifications provide reasonable assurance that the resulting annual air dose from the site due to gamma radiation will'not exceed 10 mrad, and an annual air dose from the site due to beta radiation will not exceed 20 mrad from noble gases, that no individual in an unrestricted area vill receive an annual-dose to the total body greater than 5 mrem or an annual skin dose greater than 15 mrem from fission product noble gases, and that the annual dose to any organ of an individual from radiciodines and radioactive material in particulate form with half-lives greater than eight days will not exceed 15 mrem per site.

~

At the same time these spe_ifications permit the flexibility of operation, compatible with considerations of health and safety, to assure that the public is provided with a dependable source of power under unusual operating conditions which may temporarily rcault in releases higher than the design objective icvels but still within the concentration limits spe.cified in 10 CFR Part 20.

Even with this operational flexibility under unusual operating conditions, if the licensee exerts every effort to keep levels of rzdioactive material in gaseous vaste effluents as lov as. practicable, the annual releases vill not exceed a small fraction of the concentration limits specifi,cd

~

in 10 CFR Part 20.

5 e-J

,.=O 2-16 The design objectives have been developed based on operating experience taking into account a ecmbination of system variables including defective fuel, primary system leakage, primary to secondary sys' tem leakage, and the performance of the various waste treatment systems.

Specification 2.4.2./U(0 limits the release rate of noble gases from the site. so that the corresponding annual gamma and beta dose rate above background to an individual in an unrestricted area will not exceed 500 mrem to the total body or 3000 mrem to the skin in compliance with the limits of 10 CFR Part 20.

l' For Specification 2.4.2. A(t), gamma and beta dose factors for the individual noble gas radionuclides have been calculated for the plant gaseous release points and are provided in Table 2.4-5.

The expressions used to calculate these dose factors are based on dose models derived in Section 7 of Meteorology and Atomic Energy-1968 and model techniques provided in Draft Regulatory Guide 1.AA.

Dose calculations have been mad ~e 'to determine the site boundary location with the highest anticipated dose rate from nobic gases using on-site meteo'ological datia and the dose expressions provided in Draft r

Regulatory Guide 1.AA.

The dose expression considers the release point location, building wake effects, and the physical characteristics of the radionuclides.

7 The offsite location with the highest anticipated annual dose from released noble gases is 145'o meters in the ENE direction.

The release rate Specifications for a radioiodine and radioactive material in particulate form with half-lives greater than eight days are dependent on existing radionuclide pathways to man. The pathways which were examined for these Specifications are: 1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consnmption by man, and 3) deposition onto grassy areas where milch animals graze with consumption of the milk by Methods for estimating doses to the thyroid via these pathwcys are man.

E described in Draft Regulatory Guide 1.AA.

The offsite location with the highest anticipated thyroid dose rate from radiciodines and radioactive material in particulate form with half-lives greater than eight days was determined using on-site meteorologien1 data and the expressions described in Draft Regulatory Guide 1.AA.

Specification 2.4.2.A(2) limits the release rate of radioiodines and radioactive material in particulate form with half-lives greater than eight days so that the corresponding annual thyroid dose via the most restrictive pathuay is less than 1500 mrem.

For radioiodines and radioactive material in particulate form with half-lives greater than eight days, the moc: restrictive location is Wi[ Acou 3 located M00 meters in the EpJE. direction a

In addition to the limiting conditions for vperation of Specifications 2.4,2.A and 2.4.1.B. the reporting requirements of 2.4.2.C provide that the cause shall be identified whenever the release.f gaseous effluents exceeds one-half the design objective annual quantity during any calendar quarter and that the proposed program of action to reduce such release rates to the design objectives shall be described.

Specification 2.4.2.D requires that suitable equipment to monitor and control the radioactive ~ gaseous releases are operating duiing any period these releases are taking place.

Specification 2.4.2.E limits the maximum quantity of radioactive gas that can be contained in a vaste gas storage tank. The calculation of this quantity should assume instantaneous ground release, a X/Q based on 5 percent meteorology, the average gross energy is 0.19 Mev per disintegration (considering Xe-133 to be the prir.cipal emitter) and exposure occurring at the minimum site boundary radius using a semi-infinite cloud model. The calculated quantity vill limit the offsite dose above background to 0.5 rem or less, consistent with Commission guidelines.

3.0 ENVIRONMENTAL SURVEILLANCE 3.1 NONRADIOLOGICAL SURVEILLANCE Study Plan The estuary has been exposed to the influence of the operation of Units 1 and 2 for approximately seven (?) years. During this time, the systems in the area have adapted to this influence. A pre-operational surveillance program was designed to determine the exact nature of the new stabilized conditions relative to control areas adjacent to the plant site. This surveillance consisted of system modeling with measurements of biomass, productivity, respiration and diversity in all major compartments. The information derived will serve as a baseline for comparison with the data taken after Unit 3 becomes operational.

The post-operation surveillance program is designed to determine any significant environmental effects of the operation of the power plant, particulary unpredicted and catastrophic changes.

The program consists of 4 short-term intensive surveillance program elements and 2 long-term program elements.

A period of adjustment of the ecosystem is expected concurrent with Crystal River Unit 3's initial operation. This will be a localized perturbation limited to a portion of the inner bay associated with the higher water velocity as well as the temperature increase re-sulting from the condenser discharge.

Any ecosystem which experiences a change in its environment will-undergo a period of adaption unless catastrophic conditions occur.

With the small changes anticipated with the addition of Unit 3, no catastrophic effects are expected. However, any changes in the en-vironmental conditions of a system will normally cause it to oscillate.

An example of the oscillation of a hypothetical system's productivity is shown below.

9 F-F2 In this pacticular system the final stab 11 zed level is higher than the initial level and is only obtained after a period of stablization and after going through a suppressed level following the initial per-turbation. The recognition of this type of potential response is obviously important in considering any surveillance program.

The models of the systems involved at Crystal River along with the data available indicate that the approximate time to stabilization should not exceed one year. Therefore, the time frame for the in-tensive surveillance program elements allows one year of monitoring to determine the transient response that the systems are experienc'ing.

An additional year of monitoring is required to indicate the new stabilized level. If the second year's data indicate that the systems have not approached stabilization, the monitoring will be extended for an additional year. It is anticipated that the intensive surveillance program elements should not be necessary beyond three years.

The areas in which intensive monitoring vill be performed as indicated or until stabilization occurs include the following program elements:

(1) Thermal plume model verification, (2) Benthos in discharge area, (3) Marsh grasses, and (4)

Impingement on intake screens.

In addition to the s ort-term intensive surveillance program elements designed to determine how the systems hav.e responded to the per-turbations, an on-going program element designed to obtain a diagnositic view of the condition of the environment will be continued during the operational life of the plant. This indicator program element consists i

of a number of simple measurements which will detect any major changes in the system. A second long-term program element involves chemical-industrial waste water monitoring.

3.1.1 Thermal Plume Model Verifidation Objective To verify previous calculations which predict the size and location of the effluent thermal plume.

Specification Salinity, temperature, and depth measurements shall be made in the discharge area under varying tidal conditions.

Isothermal contours shall be mapped and compared with predicted values. Two surveys shall be made during the first year of operation: one with winter conditions and one with summer conditions.

s 5

3-3 Reporting Requirement Results of the data gathered in this program elementshall be reported in accordance with Section 5.6.1.

In addition, any isotherm which exceeds the predicted area by 30 percent shall be reported as specified in Section 5.6.2.

Bases A full spectrum of thermal conditions is included during the summer and winter measurements under all tidal conditions. The limit of 30 percent was established because this is the maximum expected error 4

of the analytical' program due uncertainties caused by solar back-radiation.

3.1.2 Benthos in Discharge Area Objective To determine the ecological condition of the benthic system in the area directly affected by the thermal plume.

Specification Post-operational monitoring of productivity, respiration, diversity and biomass of the benthic system in the area adjacent to and north of the discharge canal shall be measured on a quarterly basis until the system has approached stabilization. Samples shall be taken by harvesting quadrats, by sediment cores, and by venturi pumps. The number, frequency and location of samples to be taken shall be determined from a statistical analysis of the research presently being conducted in this area.

Samples shall be stratified by macrophyte dominance. Productivity and respiration i

of the syste a shallbe determined by the methods currently employed in the modeling work.

Reporting Requirement Results of the data gathered in this program element snall be reported in accordance with Section 5.6.1.

Background

Preoperational radiological environmental monitoring programs. to establish baseline environmental concentration values, were initiated in mid-1970..One program was operated by the State of Florida Department

'of Health and Rehabilitative Services; another pregram was operated by the University of Florida.

A summary of the preoperational surveillance results is shown in Table 3.2.1.

This summary includes median val 6es of the observed environmental concentrations and 95 percentile values (i.e., values which exceed 95 percent of all the comparable measured values).

These values will be taken as the preoperational baseline concentrations.

The 95 percentile values indicate the random frequency of high measured values during the operation of the plant operation contributes neg-ligibly to the environmental radioactivity. These 95 percentile values will be used during operation to assess the probability that any observed high concentration value is due to random fluctuations in measurements rather than to a true increase in environmental con-centrations.

r Specification (Program)

Environmental media which are sampled and.nalyzed for radioactivity are shown by the two diagrams on Figure 3.2.-l.

Each oox in the dia-grams contains the name of an environmental media which is sampled.

The upper diagram shows the critical pathways; the lower diagram shows the other monitored pathways.

The operational radiological monitoring program shall consist of a continuation of the preoperational program of measurements of radio-activity in environmental media which is outlined in Table 3.2-2.

The critical pathway monitoring program which is included in Table 3.2-2 is also shown in Table 3.2-3.

Sample station locations are described on Table 3.2-4 and shown on maps on Figures 3.2-2 and 3.2-3 Typical minimum detectable concentration values are given on Table 3.2-5.

Table 3.2-6 presents the ancicipated maximum concentration increases in the critical pathway and other media for the design releases. The guidelines for these values are that limits in dose rate in unrestricted areas due to Crystal River Unit 3 operation are as low as practicable but should not exceed a 5 mrem /yr incremental increase in dose rate from radionuclides except I-131 and that the incremental thyroid dose increases from the plant's release of I-131 should be less than 15 mrem /yr. All of.the values listed in Table 3.2-6 were derived from 5

• 9

ne 1

~

3-9 the design release values listed in the " Final Environmental State-ment" (Crystal River Unit 3) and the dose models in Wash 1258. The lists of nuclides considered for determination in the environmental media include all that are anticipated from a design liquid and -gas-eous release even though most will produce concentrations far below detection limits. The design objectives of the Crystal River Unit 3 plant (insofar as environmental media concentrations are concerned) i are that the radioactivity concentrations in the environment in the vicinity of the Crystal R$ver Plant, assuming that radioactivity from sources other than the Crystal River plant are insignificant, sho~uld not exceed, over a long term, values greater than the preop'.ational baseline median concentration values plus the maximum conce: : ration increase for design release value's on Table 3.2-6.

Detailed specifications for critical pathway Environmental media are divided into three major protection elements:

(1) milk (an/or green leafy vegetable samples); (2) all other media, because of the basic differences in reporting requirements for I-131; and (3) external gamma radiation.

3.2.1 Milk and Green Leafy vegetables Specification (Program Element)

Samples of milk shallbe taken from locations and at frequencies listed in Table 3.2-2 and shall be analyzed according to the routine listed in Table 3.2-2.

Analysis shall te carried out within eight days (one I-131 half-life) of sampling.

Suitable analytical procedures shallbe used to determine the radiciodine concentration to a sensitivity of 0.5 picoeuries per liter of milk at the time of sampling. For act-ivity levels at or above 0.5 picorcuries per liter the overall error (one sigma confidence level) of the analysis shallbe within i 25%.

Results will be reported, with associated calculated error, as picoeuries of I-131 per liter of milk at the time of sampling.

If for any reason, milk samples listed in Table 3.2-2 are not available, green leafy vegetable sabples shallbe substituted for the above milk specification. The time of analysis should be similar to milk samples however, the overall error should be within 1 50%. All deviations from the sampling schedule shall be described in the semi-annual reports.

A semi-annual census of milk animals and food crops shall be conducted to determine their location and number within 10-mile radius of the plant site using reference information from county agricultural agents or other reliable sources.

If it is learned from this census that milch cnimals are present at l

a location which yields a calculated infant thyroid dose greater than from previously sampled aninals, the new location shall be added to the surveillance program as soor. as practicable.

The sampling location having the lowest calculated dose may then be dropped from the surveillance program at the end of the grazing season during which the census was con-ducted. Also, any location from which milk can no longer be obtained may be dropped from the surveillance program af ter notifying the NRC in writing of the reasons for this action.

-3.2.2 Critical Pathway Media Other Than Milk, Green Leafy Vegetables or External Radiation Specification Samplesshall be taken from locations and at frequencies listed in Table 3.2-2 and will be analyzed according to the rcutine listed in, Table 3.2-2 using procedures which shall provide. concentration values with minium detectable limits which are equal to or less than those listed in Table 3.2-5.

Both the preoperational environmental surveillance results (Table 3.2-2) and the maximum expected concentration increase due to the design releases (Table 3.2-6) have been summarized. The control station value for each media, radioiosotope and station will be defined as either (1) the upper 95% percentile value from the pre-operational program, (1) the upper 95 percentile value from operational stations outside of the plant's influence, whichever is smaller.

3.2.3 External Radiation Specification Ambient external radiation levels shall be measured at 3 scations and frequencies listed in Table 3.2-2 using procedures which will provide Tadiation level values with adnimum detectable increases over pre-operational mean background which are equal to or less than that listed in Table 3.2-5.

Reporting Requirements The results of the radiological monitoring program shall b'e reported on a routine basis as specified in Section 5.6.1.

In addition, measurements of radioactivity in critical pathway environmental media samples shall be reported on a nonroutine basis as described in Section 5.6.2.

4.0 SPECIAL SURVEILLANCS, RESEARCH, OR STUDY ACTIVI ES s "4.1 THERMAL PLUME DETFRNINATION DURING UNIT 3 OPERATION Objective To establish the location and size of the thermal plume during normal operation, under conditions of high and low tide at.d maximum and minimum intake temperature; to provf de data to verify the mathematical and physical modele so that good predictions of isotherm location under all conditions will be possible and to establish the operational monitoring-system.

General Approach and Schedule Intensive field surveys shall be conducted twice during the first year of operation. Specifically, the surveys will be done during the months of July or August when the maximum intake temperature is observed and during the months of December or January for contrast when the minimum intake temperature is observed. The thermal field measurements shall be made in sufficient locations to cover the full extent of the thermal plume.

Salinity ceasurement may be required in order to effectively decouple the plume from ambient isotherms. During the tests the behavior of the plume during both phases of the tidal cycleshall be tested. The measurements should allow for construction of the isothermal maps with 1.0*F above ambient costour intervals. These tests shall be carried out with all three Units operational and un' der at least 80 percent of full capacity. During the surveys the following conditions shall be recorded as needed to assess the extent of the thermal plume and its correspondence to a computer run with parallel parameters:

(a) plant conditions (condenser flows, intake temperature, discharge temperature, loading, etc.) of all three units. (b) hydrologi. cal conditions (tidal stage, salinity traverses, etc., (c) meteorological conditions (wet and dry bulb temperature, humidity, windspeed, wind direction, solar radiation, etc.).

The field survey measurements shall be compared to the results of the computer runs. Any modifications needed in either the physical model or the mathematicel model will then be incorporated in the models.

The models will then be available to use in the evaluation of any abnormal environmental occurrence or other modifications in plant system or equipment performance.

~

4.2 INTAKE VELOCITY DETE10fINATION Objective To measure the velocity of water at the intake screens and to verify the validity of the calculated value of intake velocity.

General Approach and Schedule Velocity currents shall be measured ~o the nearest 0.1 using a 711 mash-Mc 51rney electromagnetic. dsetion currentmeter or its equivalent. Measurements shall be =ade at the surface, 3' and 6' elevations at each side of the canal, and 3' intervals from the surface at mid-canal during normal operation of all three units within a period of one year after startup of Unit 3.

4.3 STUDY OF EROSION IN THE DISCHARGE SYSTEM Objective To study scouring and deposition in the discharge system.

General Approach and Schedule It is expected that doubling of the discharge volume flow rate by the addition of Unit 3 will nearly double discharge canal velocities and thus could increase the scouring already occurring in the canal.

If the canal turbidities were doubled, they would be approximately the same as those of the Withlacoochee River Barge Canal Waters. Much of the scoured canal sediment would be deposited about a mile and c' half down the canal and to the west where the currents diverge.

Since the scoured discharge canal particules are expected to be larger in grain size than the sediments suspended in the slower With-lacoochee waters, near-canal regions would be affected by scoured.

canal suspended sediments. These particles would most likely be redeposited once the canal currents slowed upon divergence. The contribution to the turbidity characteristics of the characteristics of the region will continue to be dominated by the suspended loads associated with the Withlacoochee River-Barg~e Canal complex.

~.

Sediment levels and particle size are being investigated in areas of concern and changes in the community structure can be detected.
