Subject:

Annual Environmental Operating Report Volume I - Nonradiological Cooper Nuclear Station NRC Docket No. 50-298, DPR-46

Dear Mr. Collins:

The requirement for submittal of this report was removed from the Cooper Nuclear Station Environmental Technical Specifications by Amendment No.

81 to Facility Operating License DPR-46 issued on March 11, 1983.

Nebraska Public Power District submits the final Cooper Nuclear Station Annual Environmental Operating Report Volume 1 - Nonradiological for the period January 1, 1983 through June 30, 1983.

We are enclosing one signed original of the report for your use and t re transmitting 18 copies to the Document Control Desk in accordance with Regulatory Guide 10.1, Revision 4.

Should you have any questions or comments regarding this report, please contact me.

2.0 ENVIRONMENTAL PROTECTION CONDITION Requirements of Section 2.3 (Chemical Analyses and Chemical Use Report) have been met as demonstrated by Table 1 and the following summary text.

2.3 Chemical Analyses and Chemical Use Report Chemical Analyses River water samples were collected by plant personnel and analyzed monthly from January through June, 1983. The samples were collected at the intake structure and the discharge canal of Cooper Nuclear Station (CNS).

Analyses for turbidity, specific conductance, chlorine, copper, iron, potassium, sodium, and pH were conducted by plant personnel as specificed in the CNS Environmental Technical Specifications (ETS). Turbidity and specific conductance at the discharge were within 10 percent of the inlet values and therefore did not exceed the ETS limitations. Total chlorine in the discharge canal did not exceed the ETS maximum concentration limit of 0.1 mg/1. The pH values ranged from a minimum of 7.1 to a maximum of 8.6. The pH was well within the ETS limitations of 6.5 to 9.0. The concentration of copper, iron, potassium, and sodium in the discharge canal does not indicate any subatantial increase due to plant operation.

The limitations of the above-mentioned parameters were not exceeded; therefore, there has been no significant chemical ef fect on the Missouri River water due to station operation in 1983.

ENVIRONMENTAL SURVEILLANCE AND SPECIAL STUDIES l

4.0 ENVIRONMENTAL SURVEILLANCE AND SPECIAL STUDIES Requirements of Cooper Nuclear Station ETS paragraph 4.1.1.2 (Plant Cooling Water System Fish Entrapment) have been met as demonstrated by Tables 1 through 4 and the following summary.

4.1.1.2 Plant Cooling Water Systems Fish Entrapment Limits Samples of fish impinged on the traveling screens were collected in accordance with the ETS. Sampling was conducted hourly at least twice per month.

During the January-June, 1983 impingement sampling (13 hourly periods),

36 fish representing 10 species were collected (Table 1). Monthly impingement rates ranged from an average of 1.5 (February and March) to 5.5 (May) fish per hour.

Predominant fished impinged , in order of decreasing magnitude, included gizzard shad, smallmouth buf f alo and bigmouth buf f alo. These three species represented 69.4 percent of the total fish impinged. Game species including largemouth bass, channel catfish, flathead catfish, and white perch, comprised only 16.8 percent of the impinged fish. Species composition and relative adundance of fish impinged during the 1983 sampling were somewhat similar to I those of previous years (Table 2). Some differences exist because this report covers only the first half of 1983.

i Seven of the 13 impingement sampling periods were during periods of darkness (1900-0700 hours) . The nocturnal impingement rate averaged 2.7 fish / hour while the diurnal impingement rate averaged 2.8 fish / hour during six sample 1 periods (Table 3) .

' 11-2

1 The rate of impingement at CNS during 1983 did not vary much. The rate of ,

impingement varied from three fish per hour in February and March to 11 fish per hours in May. ,

Fish impinged on the traveling screens at CNS are returned to the Missouri River via a return pipe from the traveling screen wash system. During 1983, 66.7 percent of the impinged fish were classified as alive and active 9 (Table 4) and can be assumed to have survived the impingement process.

Amendment 81 to Facility Operating Licensa DRP-46 for Cooper Nuclear Station issued March 11, 1983 elimated from the Technical Specifications the requirement to submit the Annual Environmental Operscing Report Volume I -

Nonradiological to the NRC. Therefore, this report covers only the first half of 1983 and is the final submittal of the " Annual Environmental Operating e Report, Volume I - Nonradiological" for Cooper Nuclear Station.
