  • Includes NRC split samples.

NOTE:

Measurement results having magnitudes that are significantly above the background of the measurement system are reported as net values plus or minus a one-standard-deviation error term.

Measurement results that are not significantly above background are reported as "non-detectable" (ND) or as less than a Lower Limit of Detection

(<LLD),

which is an estimated upper limit (with at least 95> confidence) for the true activity in the sample.

ACTION LEVEL:

(2)

Cause:

An incorrect efficiency file was used to calcu-late the results.

Corrective Action: Check the final printout from the gamma spectrometer more carefully.

Cause:

An incorrect date for beginning of the yttrium ingrowth was used in the calculations.

Corrective Action: Point out to the new chemist the significance of the ingrowth date and stress its importance in the calculation of the data.

(3)

Cause:

A short term glitch in the proportional counter produced very erroneous data.

Corrective Action: Check the proportional counter printout for obvious glitches.

Inter retation of Results Direct Radiation:

The results for direct radiation monitoring are consistent with past measurements for the specified locations.

The exposure rate data shows no indication of any trends attributed to effluents from the plant.

The measured exposure rates are consistent with exposure rates that were observed during the preoperational surveillance program.

Direct radiation monitoring results are summarized in Table 1.

2.

Air Particulates/Radioiodine:

The results for radioactive air particulate and radioiodine monitoring are consistent with past measurements and indicate no trends attributed to plant effluents.

All samples for radioiodine yielded no detectable I-131.

Gamma isotopic measurements yielded no indication of any nuclides attributed to station operation.

The results for air particulate/radioiodine samples are consistent;with measurements which were made during the preoperational surveillance program.

Air particulate and radioiodine monitoring results are summarized in Table 1.

3.

Surface Water:

The results for radioactivity measurements in surface water samples are consistent with past measurements.

Tritium was reported as present in four of the weekly surface water samples collected from Site H-15.

'ubsequent samples indicate there has been no increase nor adverse trend for tritium in surface water samples at H-15.

The highest measured tritium at site H-15 was less than 14 of the reporting level specified by plant technical specifications, Table 3.12-2.

Cobalt 58 was reported as present in two of the weekly surface water samples collected from Site H-15.

The highest measured Co-58 was less than 24 of the reporting level specified by Table 3.12-2.

Note that Tritium and Co-58 was not seen in the same sample.

No other nuclides attributed to station operation were detected.

Results for surface water samples are summarized in Table 1.

Waterborne Sediment and Food Products:

The results for radioactivity measurements in waterborne sediment, fish and crustacea samples are consistent with past measurements and with measurements made during the preoperational surveillance program.

Cs-137 was reported as present in one fish sample collected at Site H-15, Atlantic Ocean beach about a mile east of the plant.

The reported value is less than 104 of the Table 4.12-1 LLD, and less than 14 of the Table 3.12-2 reporting level.

Results for the waterborne sediment, fish and crustacea samples are summarized in Table 1.

5.

Broad Leaf Vegetation:

The results for radioactivity measurements in broad leaf vegetation are consistent with past measurements and with measurements made during the preoperational surveillance program.

Minute quantities of Cs-137 were detected in two monthly samples at a location close to the plant.

The maximum value is, less than 40% of the table 4.12-1 LLD and is less than 24 of the table 3.12-2 reporting level.

There were no indications of any nuclides attributed to plant effluents.

Results for the broad leaf vegetation samples are summarized in Table 1.

C.

Conclusions The data obtained through the St.

Lucie Plant Radiological Environmental Monitoring Program verifies that the levels of radiation and concentrations of radioactive materials in environmental

samples, representing the highest potential exposure pathways to members of the public, are not being increased.

The measurements verify that the dose or dose commitment to members of the public, due to operation of St.

Lucie Units 1

& 2, during the surveillance

year, are well within "as low as reasonably achievable (ALARA)" criteria established by 10 CFR 50, Appendix I.

The dosimeters from site S/SSE-10 gave an uhcorrected result of 12.0

+ 0.6 micro-R per hour.

Because this result is much higher than the long-term average value of 5.0 micro-R per hour for this site, and because we know of no other reason to explain an elevated reading there, it is suspected that these dosimeters were not annealed (zeroed) when they were deployed.

An estimate

, based, on this assumption. yielded a corrected result of 5.4

+ 0.3 micro-R per hour, which would be a normal result for this site.

  • Includes NRC split samples.

NOTE:

Measurement results having magnitudes that are significantly above the background of the measurement system are reported as net values plus or minus a one-standard-deviation error term.

Measurement results that are not significantly above background are reported as "non-detectable" (ND) or as less than a Lower Limit of Detection

(<LLD),

which is an estimated upper limit (with at least 95% confidence) for the true activity in the sample.
