1.0 Introducti on:

This report is submitted in accordance with St. Lucie Plant Technical Specifications, Section 5.6. l.b.

The St. Lucie Plant Radiological Envi rormental Surveillance Program for January 1,

1982 thru December 31, 1982 is summarized in Taole 1.

This program is conducted in accordance with the provisions of Appendix 8 to the St. Lucie, Unit Ho. 1, Technical Specifications.

Garden and milk animal

censuses, are required by St. Lucie Technical Specifications.

An aerial flyover was conducted in June.

Milk animal censuses were ccmpleted in March and June.

A summary of the results of these surveys is provided in Table 2.

2.0 Analytical Responsibility Radiological envirormental monitoring for the St. Lucie Plant is conducted by. the State of florida Department of Health and Rehabilitative Services (DHRS).

All samples are collected and analyzed by DHRS personnel.

3.0 Missing Data / Deviations 3.1 Mi ssing Data:

3.1.1 Missing data is.explained on page 9 of 10 of.Table 1.

Results which were not available to be included in this report due to inccmplete analyses shall be provided in a

supplementary report when they are received.

3.2 Deviations

3.2. 1 A ground water sample can no longer be collected at the specified location, 7609 Indian River Drive.

This sample is now being collected at a residence located at 7601 Indian River Drive.

4.0 Di scussion During this period, a total of 1160 samples were collected including 19 samples collected and analyzed in accordance with the DHRS/DOE split sampling program.

Table 1 summarizes the range and mean results for all sample locations and where applicable the range and mean results for control locations and for sample locations which yielded the highest annual mean levels.

In order to meet the specif'ied detection limits for 1I in milk samples, DHRS has been contracting these samples to an outside laboratory.

DHRS has now aquired the capability to perform this analysis as specified and is performing the analyses in-house beginning with the 3rd quarter 1982.

Continuous air sampling.was conducted at nine di fferent locations surrounding the St. Lucie Plant.

Samples were collected and analyzed for gross beta radioactivity and radioiodine (131I) on a

weekly basis.

In addition the air particulate filters were ccmposited and monitored for gamma radiation and Sr, DSr on a

monthly and quarterly basis respectively.

All results for this reporting period were within the normal expected range for

)g~kground measurements.

Measurements for gamma, 8 Sr, 9DSr ana I were al 1 nondetectable.

Air monitoring results are summarized in Table 1

4. 2 Di rect Radi.ati on Monitori ng:

Continous monitoring of ambient radiation exposure rate by thermal-luminescent dosimeter (TLD) was provided routinely at nine different sample locations surrounding the St. Lucie Plant.

TLDs are collected and analyzed on a quarterly basis.

During analyses of the TLDs for the first quarter, it was noted that an instrument malfunction was causing suspiciously low readings; These results were subsequently

-corrected and reported based upon test measurements performed by DHRS.

Except for location

H12, an FPL substation located-in Stuart K,.~z q Florida, all exposure rate measurements during 1982 were within the normal expected range of background measurements.

At location

H12, the exposure rate is influenced by the presence of natural radioactivity contained in backfill used at, this location.

The exposure rate at H12 is consistent with past, measurements.

Exposure rate measurements are summarized in Table 1

4.3 Water Sampl es:

As a part of the'St.

Lucie Radiological Enviroenental Surveillance

Program, surface water (4 locations) potable water (3 locations) and ground water

( 1 location) samples are collected.

iso isotopes whi ch could be attributed to operation of the St. Lucie Plant were detected in any water samples collected in 1982.

The gross beta results for the potable water 'and ground water wells are from natural radioactivity and are within the normal expected range of background measurements.

Water sample results are summarized in Table 1.

4.4 Sediment and Sand:

In addition to water samples, samples of bottom sediment (6

locations) and of beach sand (3 locations) are routinely collected around the St. Lucie Plant.

During this period, radioisotopes which could be attributed to the operation of the St. Lucie Plant

were detected in samples taken frcm within the plant discharge canal.

During normal operation, small amounts of radi oactivi ty are periodically released in effluents from the plant.

Consequently measurements of low concentrations of radioactivity in samples taken near the plant discharge would not be.unexpected from time to time.

The St. Lucie Plant discharge canal ccmprises part of the plant restricted area.

The concentration of radioactivity reported in the discharge canal sediment however, is less than one third of that which would be permitted continously in unrestricted area

'aters.

Further, the'oncentrations of

~

Cs and

""Ce are less than that which have been measured in environmental samples in Florida even before the operation of nuclear plants within the state.

Except for the discharge canal samples, all sand and sediment samples yielded nondetectable results.

The results for sand and sediment samples are summarized in Table l.

4.5 A uatic and Terrestrial Biota:

The St. Lucie Plant Radiological Environmental Surveillance Program also includes samples of aquatic and terrestrial bi ota collected from several locations around the St. Lucie Plant.

All results for these sampl'es are within the expected normal range and are consistent with past measurements including measurements made dur ing the pr e-operational surve il lance period.

The results for aquatic and terrestrial biota samples are summarized in Table l.

5.0 Conc 1 us i ons With respect to the St. Lucie Plant, the operation of St. Lucie Unit Ho.

1 is not contributing significantly to the presence or buildup of radioactivity in the enviroreent around the St. Lucie Plant.

Operation of St. Lucie Unit No.

1 is not contributing significantly to the exposure of any individual or population group or to any radiological consequence involving the health or safety of any individual or population group.

The concentrations of any radionuclides reported in Table 1 are much less than that permitted for those radionuclides in unrestricted areas as provided in 10CFR20, Appendix B.
