2.0 ENVIRONMENTAL PROTECTION CONDITION 2 2.1 Thermal 2.1.1 Maximum AT Across Condenser 4
Objective To limit thermal stress to the aquatic ecosystem by limiting the maximum AT across the condenser during operation.
Specification:
~ a. The maximum differential temperature across the ' condenser shall not exceed 15*F during normal operation with all four circulating water pumps in operation. j
- b. If one or two circulating water pumps are out of service at any given time the maximum condenser AT shall not exceed 30*F; and Specification 2.1.2 of this Appendix shall be met.
Monitoring Requirement ;
The temperature differential across the condenser shall be monitored .
, every hour utilizing the computer output of the condenser inlet and outlet temperature measurements. The range of these measurements shall be 0-150*F 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 0-150*F range and 0.5%
accuracy.
Bases Maximum AT's of 15*F with 4 circulating water pumps operating
(%1700 cfs flow) and 30*F 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 j RTD's at tha inlet and outlet of the condensers provides that AT across the conder. rs. j 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 have shown that a 30*F 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 15'F AT at 1700 cfs except on the surface of the discharge embayment.

l 2.1.2 Maximum Discharge Temperature Objective 1
'I To limit thermal stress to the aquatic ecosystem by limiting the plants, maximum discharge water temperature.
1 Specification The condenser discharge water temperature shall not exceed 105*F for more than 2 consecutive hours. If the water temperature exceeds 105'F for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, the plant power level shall be reduced to the extent necessary to maintain the discharge water temperature at i .1105*F, unless there is an emergency need for the lost power.
(Define emergency need for the lost power.)
I Monitoring Requirements Condenser discharge water temperature shall be monitored every hour utilizing the average of the computer output of the condenser dis-charge RTD readings. The RTD's have a 0-150*F range and an accuracy of 0.5%.
If the plant computer is inoperable, the condenser discharge water temperature shall be monitored at least once per shif t utilizing the condenser temperature recorder with a 0-153*F range and 0.5%
accuracy.
Bases .
The 105'F maximum discharge water temperature limit is set to assure that the Dardanelle Reservoir temperature does not exceed 95'F as established by the applicabitc water quality criteria. The use of the condenser discharge RTD's prevides the circulating water discharge temperature prior to mixing with the Dardanelle Reservoir water.
2.1.3 Maximum BTU /hr Not applicable.

I Specification (General) l All plant chemical discharges except that from the plant sanitary system j shall be diluted by the plant circulating water during release to assure
that the stated objective can be achieved.
2.3.1 Biocides Specification
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 con-centration of free available chlorine residual (in the form of molecular chlorine, hypochlorous acid, and hypochlorite lon) added to the circulating water system shall be limited to a maximum of 1 mg/1. Total available chlorine residual in the plant effluent shall be less than 0.1 mg/1.

%_ m Bases The once-through circulating water flow taken from the Illinois Bayou arm of the Dardanelle Reservoir will pass through the turbine condenser and will be discharged into an 80-acre embay-
' < ment 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 3.,
of total available chlorine residual below 0.1 mg/l in the
. ?37i effluent. It is estimated that Unit 1 chlorine usage will be 330,000 lb / year.
2.3.2 Corrosion Inhibitors -
Specification There shall be no discharge of sodium nitrite to the plant discharge.
Monitoring Requirement i
The closed cooling water system of the plant shall be sampled weekly to ascertain whether sodium nitrite leakage from these systems has occurred. (Provide method of analysis and level at which corrective action will be taken.)
Bases The closed cooling water systems are treated with sodium nitrite or sodium nitrite based inhibitors. Under normal conditions, there will be no discharge of the sodium nitrite inhibitor to the plant dis charge. Any leakage from these sytems would normally be un-detectable 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 af ter initial charging of all systems will be 1500 lb/ year.

- MINIMUM SAMPLING FREOUENCY (1) When radioactivity level is greater than 10 percent of the limits of Safety Specifications 3.1.4, the i- sampling frequency shall be increased to a minimum of.once each day.'
d (2) E determination will be started when gross beta-gamma activity analysis indicates greater than 10 pCi/ml f;. and will be redetermined each 10 pCi/ml increase in gross beta-gamma activity analysis. A radiochemical j 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 j> and gaseous activities, radiochemical analysis for Sr 89, 90, and tritium analysis .
(3) When gross activity increases by a f actor of two above background, an iodine analycis will be made and performed thereafter when the gross beta-gamma activity increases by 10 percent. ,
(4) When activity level exceeds 10 percent of the limits of Specification 2.4, the sampling frequency shall ,
t be increased to a minimum of once each day. When the gross activity release rate exceeds one percent of '
- a maximum release rate and the average gross activity release rate increases by 50 percent over the previous day, an analysis shall be performed for iodines and particulates. $
1 (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.
The detectability limits for activity analysis are based on the technical feasibility and on the potential 4
(6)
. significance in the environment of the quantities released. For some nuclides, lower detection limits may l be readily achievable and when nuclides are measured below the stated limits , they should also be reported.
(7) For certain mixtures of gamma emitters, itmmay 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, i
(8) Analyses shall also be performed following each refueling, startup or similar operational occurrence ,
, which could alter the mixture of radionuclides.

Herd 5 miles east. Samples will
- be analyzed for Iodine-131, Strontium 89-90 and gree wii. ting isc,tenes.
The area within five (5) miles of the plant will be surveyed for the locations of animals (cows, goate,) producing milk for human consumption. These locatic;s will be included in the milk sampling program as soon as the necessa*.y arrangements can be made. The sampling frequency for locations n .arer 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 as in Table 4-1, and monthly composites will be analyzed for radiostrontium and gamma enitters. 4.2.11 Vegetation Sampling i 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, s.nd fall) . Food crops and pasturage in the vicinity of the plant will also be collected as available at harvest i time. Appropriate analyses of all samples are performed in accordance d

4.2.12 Soil Sampling - Soil samples are collected semi-annually at the same locations as vegetation samples and analyzed for gross alpha and gross beta and gamma emicting 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 l 7 'gs specifided in AEC Regulations 10 CFR - Parts 20, 50, and 100. This
, Radiological Monitoring Program includes measurements made un the air," water, and land environments to insure that these limits are observed.

j ( Operating Report within 60 days af ter January 1 and July 1 of each year. The first such period shall begin with the date of initial criticality. The report shall be a summary of the results of the environmental activities for the 6 month period and an assessment of the observed impacts of the plant operation on the environment. The report shell include a summary of the quantities of radio-active effluents released from the plant as outlined in USAEC Regulatory Guide 1.21, with data summarized on a monthly basis following the format of Appendix A thereof. 'k-- If statistically significant variations of offsite environmental radionuclide concentrations with time are. observed, a comparison of these results with effluent releases shall be provided. Individual samples which show higher than normal levels (25% above background' for external dose, or twice background for.radionuclide content) shall be noted in the reports. Results of all radiological samples taken shall be summarized on a quarterly basis following the format of Table 1 for inclusion in the semiannual report. In the event that some results are not available within the 60 day period, the report should be submitted - noting and explaining the reasons for the missing results. The l missing data shall be submitted as soon as possible in a supplementary J report. 5.6.2 Non-Routine Reports
- a. Radioactive Discharge The reporting requirements for radioactive discharges are
.,. specified in Section 2.4 of the Technical Specification.
- b. Radiological Environmental Monitoring i
(1) If a measured level of radioacti ity in "critica pathway environmental medium samples" aioicates that the resultant annual dose to an individual from ttar.e levels could equal or exceed 4-8 times the design objeccive, a plan shall be sdbmitted within one week advising the AEC of the proposed action to ensure the plant related annual doses will be
. within the design objective. For example, with an I-131
- design objective of 15 mrem /yr to the thyroid of any
,j' individual, if individual charcoal filters show I-131 j concentrations in air of 8 x 10-12 pC1/cm3 (8 pei/m3 ) or l greater (3 x 10-14 pCi/m3 if the milk pathway is involved) ,
3 or if individual milk samples show I-131 concentrations l of 19 pCi/l or greater, the results shall be reported i along with a proposed plan of action, as discussed above. d I lx - -

i i I 6.0 SPECIAL SURVEILLANCE, RESEARCH, OR STUDY ACTIVITIES (This section should contain a description of special surveillance, research, or study activities acceptable to the staff that are not included in Section 4. Examples of the types of activities
. that are appropriate for inclusion in this section include:
thermal plume mapping and the program to determine characteristics of fish spawning activities in the Reservoir) . (The description of these studies should include a summary of the objecrive of the activity, the general approach to accomplishing the objective, a schedule of significant milestones, and the plan for reporting the results to the AEC.) l 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 each depth will be sampled sequentially at frequent intervals and the data will be automati- 1 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 used for information display. (Provide nore details) This survey will be conducted as necessary to map the plant's l thermal plume and insure compliance with ~ applicable water quality criteria. Background temperature data will be obtained orior to plant operation. (Provide schedule for completion, desc.'be data utilization and verify compliance with applicable criteria under low flow conditions) . ,

- of the Dardanelle Reservoir relative to fish spawning activities.
Program Specifications: l l This program relates to the fish spawning activities during the i Spring of 1973 and shall determine the spawing fish populations I and sizes in the intake canal, discharge embayment, and one 1
" control area" (sample area 19) .
Samples shall be taken by fish nets selected to provide optimum spawning information. The positions foi 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. (Provide more details) . Samples taken by net will be separated according to size, and reported by number under each size. Data will be prepared noting any significant changes or unusual conditions. (Provide schedule for completion). Reporting Requirements : The results of this survey shall be reported to the AEC upon its completion. Bases : (Provide rationale for program) .
