Pre-Operational Environmental Radioactivi ng Report Oconee Nuclear Station AECDocketNos.Ci0-269,'270,and287
Dear Sir:
This is in reply to your letter of December 8,1971 forwarding comments T
from the U. S. Department of Interior, Fish and Wildlife Service on subject report.
d
)Y 00CKETED USAEC 1.
In regard to benthic organisms:
ff DEC2 71971
- 3 Page 6, item 6 of subject report, specifically listing among others, bottom organ' v, was a requirement that was received G REGULATCRY from the AEC late in.he pre-operational program period.
A fyLyE more. accurate requirement for these samples is stated in the b
j Final Safety Analysis Report, Section 2.7.2, revision 6, dated 6/22/70, which reads, "... samples are collected depending on I
availability." Soon after this requirement was received person-nel from the South Carolina Wildlife Resources Department who furnish us with fish samples, conducted an extensive survey j
downstream of the effluent release point and were unable to find bottom organisms or crustaceans (crayfish),which were also required, in quantity. They did give es a small quantity of fresh water clams which we subjected to gamma analysis, finding only natural potassium-40.
However, in order to resolve the problem and your concerns in
~ this regard, we will attempt to gather sufficient quantities of bottom organisms sometime-prior to the. operation of Oconee Unit 1 and subject them to comprehensive radioactivity analysis and measurement so that we will have background data available for comparison purposes during Unit 1 operation.
2.
In regard to the nearest downstream sampling ' station from the radioactive waste discharge point:
The answer depends on the type sample.
For example, a water sampling station is located approximately 2640 feet downstream.
5G17 LL[
y.. %.
O U. S. Atr -J c Energy Commission Page 2 December 23, 1971 Bottom sediment is collected at the shortest distance downstream where sediment persists and is not swept away by the Keowee hydroelectric plant operation.
This is within the one mile Exclusion Area. Bottom organisms will be collected from the nearest lat downstream where they can be found.
Because of temporary construction conditions in the area this may be several miles downstream for freshwater clams.
Also there is a dearth of bottom organisms upstream in Lake Keowee because it is a new lake. This obviously makt.s comparison of upstream and downstream samples quite difficult.
But, this situation will be resolved during the operating period by analyzing downstream samples for the specific radionuclides released from the station in the liquid waste effluent.
We expect that the above information will answer your questions.
