ARKANSAS POWER 1 LIGHT COMPcNY DOCKET NO. 50-313 ARKANSAS NUCLEAR ONE - UNIT NO. 1 AMENCMENT TO FACILITY ODERATING LICENSE Amendnent No. 51 License No. DPR-51 1.
The Nuclear Regulatory Comission (the Comission) has found that:
A.
Thd application for amendment by Arkansas Power & Light Company (the licensee) dated March 9,1979, as supplemented December 9, 1980, complies with the standards and regiairements of the Atomic Energy Act of 1954, as amended (the Act), and the Ccmmission's rules and regulations set forth in 10 CFR Chapter I; B.
The facility will operate in confomity with the application, the provisions of the Act, and the rules and regulations of the Comission; C.
There is reasonable assurance (1) that the activities authorized by this amendnent can be conducted without endangering the health and safety of the public, and (ii) that such activities will be conducted in compliance with the Comission's regulations; D.
The issuance of this amendment will not be inimical to the comon defense and sectJrity or to the health and safety of the public; and E.
The issuance of this amendment is in accordance with 10 CFR Part 51 of the Comission's regulations and all applicable requirements have been satisfied.

4-11 Frequencies of sampi ng were chosen to obtain a trend of aquatic life in the area. Most fish surveys are set up to oe conducted in the suniner because the fish are more plentiful at this time of year.
It is felt that more frequent sampling of the organisms would produce repetitive data. However, less frequent sampling might yield erratic data from which no trend could be detected.
The data will be evaluated in relation to preoperational data ob-tained by AP&L, UALR, Ark. Tech., and various 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.
(2)
Imoingement of Organisms Objective The objective is to monitor those fish impinged on the intake screens to permit an assessment of impingement impacts. Potential impacts of concern are effects on the fishery resource and dissolved oxygen re-source of Lake Dardanelle.
If these impacts are significant, acpropriate state and federal agencies responsible for fisheries shall be consulted, and the necessary modifications to the intake system shall be implemented to satisfactorily reduce these impacts.
Specification Fish trapped on all of the intake screens shall be sluiced to a collec-tion basket where they shall be identified, counted and weighed following a twenty-four (24) hour sampling period twice each week.
If the weight of fish and trash impinged during any given 24-hour sacpling period exceeds 150 pounds, two replicate subsamples of 75 pounds each shall be taken and their averages used for extrapolation and detennination species data for the total weight and nuntier of each species impinged. Length and weight -
or each fish in a subsample shall be detennined for each species collected up to 25 fish per specie.
If the number of fish in a subsample for a particular species is greater than 25, 25 fish plus 1". of N-25 (where N is i
l the number of fish for a particular species in the subsample) shall have i
their length and weight measured. Total biomass of all fish impinged shall be estimated regardless of the number impinged. Tabulations of this data shall be made.

4-12 Fish shall be disposed of in a manner consistent with U. S. Environmental Protection Agency, Arkansas Department of Pollution Control and Ecology and Arkansas Game and Fish Comission Guidelines.
Reporting Requiremenc Monthly results from this study shall be submitted to the NRC, Division of Operating Reactors, no later than 30 days after the end of the reporting month. The reports shall contain the foliewing infomation:
the date of the sample, the species collected, the number or estimated number impinged in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for each species, the modal length (in mm) for each species, the maximum length (in m) for each species, the modal weight (in g) for each species, and-the number of pumps coerating during each sample collection.
A summary of the impingement results shall be included in the report required by Specification S.6.1.
Bases Tne purpose of this program is to pamit accc=plishment of the specification objective. Surveillance frequency is based on previous surveillance data at Arkansas Nuclear One indicating large impingements during the period October through Marqh. Subsampling is done to reduce the sampling effort and replicates are taken to reduce subsampling error.
Length and weight deteminations are made to determine __ impingement selectivi.ty.
(3).Entrainment of Ichthvoolankton Objective Tne objective of the entrainment study is to determine the effects of operation of the Circulating Water System on the ichthyoplankton.
Soecification A sampling program shall be implemented to determine estimated numbers of ichthyoolankton passing through the circulating water system.
It shall be assumed that those organisms passing through the system undergo a 1 COT, Il mortali ty.
Intake samples shall be taken in the intake canal. Physio-chemical parameters to be monitored at sampling shall include water temperature, dissolved oxygen and pH.
Ichthyoplankton shall be samoled monthly during the months of April through September. Samples shall be taken at eight-hour
[
intervals over 24-hour periods.
