1 License Ho. - DPR-67 Docket Ho. 50-335 ANNUAL RADIOLOGICAL EHVIR0$1ENTAL NOHITORIHG REPORT for The Period:
1-01-81 to 12-31-81 Prepared 3-19-82 (Suppl anented July 1982) 8504090507 820802 PDR ADOCK 05000335 R
1.0 Introduction This report is submitted in accordance with St. Lucie Plant Technical Specifications'ection 5.6'. 1.b.
The St. Lucie Plant Radiological Envi ronmental Sampling Program for January 1,
1981 thru December 31, 1981 is summarized in Table 1.
Tnis program's conducted in accordance with the provisions of Appendix 8 to the St.
Lu'cie, Unit No. 1, Technical Specifications.
Except as otherwise noted herein, the minimum Technical Specification requirements for sampling and analysis have been met or exceeded.
Garden and milk animal
- censuses, are required by St. Lucie Technical Specifications.
A garden census was conducted i n June.
Milk animal censuses were conducted i n February and June.
A summary of the results of these surveys is provided in Table 2.
2.0 The Monitoring Program
- 2. 1 Analytical responsibility Envi ronmental radiological monitoring at the St. Lucie Plant is carried out by the Department of Health and Rehaoi litative Services of Florida (DHRS).
Samples are collected and analyzed by UHRS personnel.
2.2 During the period, a total of 1158 samples were collected including 19 samples collected and analyzed in accordance with tne DHRS/DOE split sampling program.
Table 1 summarizes the range and mean results for all sample locations and where applicaole the range and mean results for the control locations and for sample locations which yielded the highest mean levels.
The numbers of samples which yielded detectable measurements compared to the total numbers of samples analyzed are also indicated.
3.0 Hi ssin and Non-Confonain Data During this period, five samples for particulates in air were missed.
A description of the affected samples and the reason for not being collected is provided in Table 1A.
- 3. 2 Non-Conformi n Data In order to meet the detection limits for 131I i milk, DHRS sends samples to an outside contractor.
During the period January 1,
1981
- December 31, 1981, the detection limit for 1~11 in milk was exceeded for six samples.
In one instance, a sample did not reach it's destination and was apparently lost in the mail.
DHRS'etection limit for that sample was used in lieu of the missing result.
The remaining instances
~here the detection limit for 131I in milk was exceeded occurred because of sample spoilage during shipment to the outside laboratory.
A descri ption of the affected samples is provided in Table 1A.
Based upon the sample results that were obtained during this period as well as historical data for the St.
Luci e Plant, no changes to the conclusions of this report would be expected because of the missing or non-conformi ng data.
4.0 Discussion and Inter r etation of Results
- 4. 1
,Atmospheric Weapons Test During the first half of 1981, the radiological effects of a Chinese Weapons
- Test, which took place on October 16, 1980, continued to oe reflected in environmental samples collected as a part of the St.
Lucie Plant Radiological Environmental Surveillance Program.
. Similar effects were observed throughout the U.S.
and Florida.
Airborne particulate gross beta radioactivity peaked in April 1981 (0.370 pCi/m3) then decreased during the second and third quarters.
Average airborne particulate beta radioactivity for the fourth quarter was in the normal expected range at 0.019 pCi/m3.
Gamma analyses on particulate filter samples collected during the affected period revealed the presence of particulate form fission-products such as 106Ru and 95Zr.
There were no detectaole measurements of radioiodines in any of the air samples.
Ho fission products were detected, on filter samples collected during the fourth quarter.
Two garden vegetation samples that were collected in Narch 1981 revealed abnormal levels of 137Cs (2790 pCi/kg ave.)
and "5Zr (220 pCi/kg ave.)
Based upon the timing of the sample collections and the known atmospheric radiological'onditions throughout the sample growing period the most probable explanation for the elevated levels of fission product radioactivity in the garden samples is that they they were effects associated with the October 16 weapons tests.
- However, due to the close proximity of the garden to the St; Luci e Plant (approximately 2 miles WSW), and the unavailability of suitable control specimens for the garden
- samples, release data from the St. Lucie Plant were evaluated to determine if a correlation existed between the released data and the measured levels of radi oactivitg in the garden samples.
Since there were no measurable levels of >>~Cs or its parent isotope 137Xe in'airborne effluents fran the St. Lucie Plant and since the winds were blowing in the WSW direction for only approximately 2$ of the total time, the're is
no apparent correlation of the measured levels of radi oactivi ty in the garden samples to operation of the St.
Luci e Plant.
It has been further noted that elevated levels of 137Cs and 95zr have been observed during the same period by other licensees within the state of Florida.
Effects from the weapons test therefore remains the most likely explanation for the elevated level of radioactivity in the garden sample.
It should also be noted however, that 137Cs levels in the same range have been measured in other types of Florida vegetation prior to the operation of nuclear power plants in
4.2 Water Samples During normal operation of St. Lucie Unit 1, small quantities of radioactivity are periodically released from the plant.
As a result tritium may from time to time be detectable in the plant discharge canal.
During this period (January 1 - December 31, 1981) tnere were detectable.levels of tritium in three of of the twelve samples collected from the discharge canal.
As indicated in Table 1, the highest concentration of tritium observed in the St. Lucie Plant discharge canal was 7200 pCi/1.
This level of tritium represents only about 0.24$ of the allowable limit for tritium in water in unrestricted areas.
In fact, this amount of tritium is only aoout 36$ of that which would be allowed if the discharge canal represented a source of dri nking water.
- However, no drinking water sources are affected by effluents from the St.
Lucie Plant.
l<o other radioi sotopes which could be attributed to the operation of the St.
Lucie Plant were detected in water samples from the discharge canal or environment surrounding the St. Lucie Plant.
4.3 Other Environmental Sam les Bottom samples collected from within the St. Lucie Plant discharge canal indicate that there is a detectable level of 60Co in the canal's bottom sediment.
The levels reported are low and are consistent with previous measurements.
Atmospheric fallout from the October 16 Chinese Weapons Test is
'esponsible for the presence of 95Zr which was detected in. some of the beach and soil samples collected during the first and second quarters or 1981.
Neasurements of radionuclides and/or radiation for all other environmental samples provided in Table 1 are consistent witn measurements made during pre-operational surveillance programs 5.0 Conclusions The Chinese weapons test conducted on Octooer 16,
- 1980, had a
significant impact on radiological environmental samples collected in the vicinity of the St. Lucie Plant during the first two quarters of 1981.
With-respect to the St. Lucie Plant, the operation of St. Lucie Unit No.l is not contributing significantly to the presence or buildup of radioactivity in the environment around the St.
Lucie Plant.
Operation of St. Lucie Unit No.l 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
