Environmental Radiolo ical Honitorin

(.1-01-79 to 6-30-79)

Introduction

. This report is submitted in accordance with Turkey Point Plant Technical Specifications.

All environmental samples were collected and analysed in conformance with the requirements of the Technical Specifications.

The minimum frequency of collection and analyses for specific radionuclides and sample types as required by these specifications has been me't or exceeded.

The Monitorin Pro ram Period Covered:

This current report covers the period from January 1,

1979 to June 30, 1979.

Anal tical Res onsibilit

.: Environmental radiological monitoring at Turkey Point Plant is carried out.

by the Orlando Radiological Laboratory of the Department of Health and Rehabilitation Services of Florida (DHRS).

All samples are collected and analysed by DHRS personnel.

Number of Sam les Anal zed:

A total of 698 analyses

~

on samples collected from 35 different sampling locations were performed during the period of this report.

TABLE 1 summarizes the mean and range values of these analyses.

S lit-Sam le Anal ses:

Twelve samples were collected to be analyzed by the DHRS/ERDA Split-sampling program.

Evaluation of Data a)

As applicable, TABLE 1 reports'ata for sampling locations that have concentrations of a particular radionuclide higher than the observed mean for all sampling locations where the same type of sample material was collected and analyzed for that particular radionuclide.

b)

Recognition must be given that data reported herein could be influenced by the residual fallouts from the Chinese weapons tests of September, 1977 and the fallout from new Chinese tests carried out on Harch 14, 1978 and December 14, 1978.

q~~>.x@ & l l

0 Q

c)

The radioactive isotope Ce found in sponges collected at locations T-59 and T-93 is due to fallout.

Other locations showing radionuclide concentrations possibly attributable to fallout are:

Estuarine Sediments:

'Aquatic Biota, crustacea:

fish:

Turtle grass:

Soil T-66, T-94 T-94, T-66, T-81 T-66, T-59, T-95 T-66 T-55 d)

The

,H concentra$ ion at sampling location T-84 is consistent with H levels previously observed in the cooling canal system.

The other canal lgcation,,

T-97, had a slightly lower concentration of H.

e)

No significant increases above previously reported data have been observed in Gross Beta-DS and H

concentrations at location T-75 in the Fresh Mater Canals.

f)

The H concentrations in the Ground Water, Wells at sampling locations T-91 and=T-92 continue to be of the same ma'gnitude as previously reported.

g)

The concentration levels of Co and Co in the 58 60 bottom sediments of the cooling canal at sample location'-84 continue to.be of the same order of magnitude as previously reported.

All data have been compared with pre-operational data'and have been found to be within the

+ 2a limits observed.

i)

Where applicable, comparisons of test sample location data with that of the control sample show no differences in concentration levels except as noted in TABLE l.

Concl us i ons The concentration level of any radionuclide reported in TABLE 1 will contribute much less than the maximum permi ssibl e 1 imits of indi vi dual or popul ation group exposure that could result if there had been a continuous intake.of radionucli.des having concentration values equal to those permitted by APPEHOIX B, TABLE II, 10 CFR20.. Therefore, the operations of Turkey Point Plant Units 3

8 4 are not contributing harmful effects-

,of irreversible damage to either the environment or to the health and safety of individuals or population groups in'he regions surrounding Turkey Point Plant.
