I. INTRODUCTION The Radiological Environmental Monitoring Program provides information

. which can be used to assist in assessing the type and quantity of radiation exposure in unrestricted areas resulting from plant operation. The Program is conducted via a contract with the University of Florida,

. Department of Environmental Engineering Sciences, Gairesville, Florida and a grant to the State of Florida, Department of Health and Rehabilitative

. Services, Orlando, Florida. The parts of the Program for which each are responsible are listed in Table I-1. In essence, the Program provides a continuation of the preoperation program so that any increases of radioactivity in the environment can be detected. No pathway has shown any confirmed increases of radioactivity in the environment due to plant operation during this report period. Two major items of change in the Program during this report period were in the areas of results reporting and sample analysis lower limits of detection, LLD's.

Early in 1977, an annual report for 1976 was prepared and reviewed in order to anticipate and correct potential problems in the Program.

Many areas were improved upon, the biggest of which was in forwarding data to Florida Power Corporation on a timely basis for review. Update reports had been sent in 197.6 but they were sporadic and did not contain l

sufficient specific data for a critical review. Development of a computer program (Environmental Radioactivity Data Analysis Program [ERDAP]) was begun by the University to forward better data faster. In the meantime,

' the State forwarded all data to FPC as well as to the University and the University sent FPC monthly reports on sample collection and analysis completion. Beginning in September 1977, the ERDAP wa.s complete and the -

monthly reports consisted of the output of this program. This prugram not only'kept track of sample collection and analysis completion, it also printed out the analysis results of each sample for each psthway, the LLD's of each sample, and a year-to-date summary of all samples for each pathway in the required report summary format. This made for better reviews in that missed samples were easily determined, trends of radio-activity in the environment could be detected, and sample LLD's could be evaluated. The summary tables in this report are from the ERDAP output and are identical in form and required content as Environmental Technical Specification Table 5.6-1 (Table 1, Reg. Guide 4.8,12/75).

The second area of major change was in the sample analysis LLD's for the University. From the review of the 1976 report, it was apparent that many sample LLD's were above those required by ETS Table 3.2-5A. A new, more efficient GeLi crystal was purchased in May. Sample sizes were increased and sample count times were lengthened. These efforts lead to lower and lower LLD's each month. License Event Reports 77-lllE,134E,141E,144E, and 164E give the number of LLD's for each analysis that were in excess of those raquired. It is anticipated that all average annual LLD's for 1978 will be within the ETS requirements.

1

One point that will be mentioned throughout the report is the lack of operational statistics. The Preoperational Program results cover four years' worth of data-taking. There can be no validity in comparing the

. results from one operational year to the preoperational data. This is especially true in the as..'ual and semiannual samples. In addition, l preoper.itional values less thari the preoperational minimum detectable activities (MDA's) have been included in the preoperational results

. where corresponding operational values have not. This tends to artificially

. elevate the operational results in comparison to the preoperational results.

In the summary analysis tables, two terms are used which need explanation.

The term "ND" means that the activity of the nuclide for the samples was less than half of the LLD's for those samples. The term "<LLD" means that the activity of the nuclide for the samples was less than the LLD's for those samples. In this way, an apparent change in activity below the lower limits of detection can ba t. rended without getting bogged down in " actual" activity 1 values.

Finally, the statistical evaluation of the operational values includes the median values. This is done solely for comparison to preoperrcional results since the results of the operational progrem are not numerous enough to lend validity to the median values.

II. MILK AND GREEN LEAFY VEGETABLE CENSUS Environmental Technical Specification 3.2.1 requires a census of animals producing milk for human consumption to be conducted seminannually.

If this census fails to locate any such animals, a census of gardens producing fresh leafy vegetables for human consumption is required annually.

On August 23, 1976 an aerial garden survey was performed as a baseline census to get an idea of the number of gardens in the area. Two garden sites were located within five miles of the plar,t. The first was a year-round garden in the east sector at 4.5 miles from the plant. The second was a spring garden in the east-southeast sector again at 4.5 miles from the plant.

A milk animal census was conducted on December 7,1976 and the only milk cow was found in the east sector at 4.5 miles from the plant (on the same farm as the year-round garden).

No garden survey was therefore required. The second semiannual milk animal census was performed on July 25, 1977 with the same results as the first.

On October 10, 1977, the USNRC was notified in writing that the milk cow in the surveillance program was no longer being milked for human consumption and as such, the location was being dropped from the program.

A green leafy v.egetable sample was then collected from the year-round garden even though it was not required at that time. ,

On December 12, 1977, the third semiannual milk animal census was performed and again the results were the same as the first. It was subsequently determined that the cow was producing milk but not for human consumption. It was in fact being dried up and let out to pasture until the spring. A garden census was then instituted but was not completed withir, the period of this report.

AIR INHALATION PATHWAY The Air Inhalation Pathway is one of two pathways split between the University and the State. In addition te the assigned stations, the University operates a station at C47 Weekly Grocs Beta Analysis The sumary for the gross beta analysis is in Table III-1. Four weekly samples were not collected and analyzed:

C40 for the week of 01-03-77 because of power failure C46 for the week of 01-24-77 because of #er failure C18 for the week of 02-28-77 because of power failure C41 for the week of 09-23-77 because of loss in the U.S. Mail All weekly samples that were collected and analyzed had LLD's equal to or less than those required. Six samples had activites greater than 10 times the preoperational 95 percentile values (but not 10 times greater than the 95 percentile value of the stations outside the influence of the plant):

C04 for the week of 10-03-77 due to the fallout from a Chinese weapons test

' C07 for the week of 10-03-77 due to the fallout from a Chinese

weapons t'est C18 for the week of 10-03-77 due to the fallout from a Chinese weapons test C26 for the week of 10-03-77 due to the fallout from a Chinese weapons test C40 for the week of 10-03-77 due to the fallout from a Chinese weapons test C41 for the week of 10-07-77 due to the fallout from a Chinese weapons test Deleting the above six stations, the statistical analysis of the data is as follows:

Preoperational Mecian Value = 0.029 pCi/m3 Preoperational 95 Percentile Value = 0.12 pCi/m3 Operational Mean Value = 0.103 pCi/m3 Operational 95 Percentile Value = 0.698 pCi/m3 O

7

There are no critical stations for this type of analysis.

While it appears that the operational values have increased by a factor of five over the preoperational values, the statistics for the four years

- worth of preoperational data far outweighs the present year's worth of data. In addition many preoperational results were reported for data

- that was less than the minimum detectable activity, whereas these low values are not included in the operational statistics.

Weekly I-131 Analysis The sumary for the I-131 analysis of weekly samples is in Table III-2.

i Five weekly samples were not analyzed:

C41 for the week of 04-08-77 because the filter was lost C47 for the week of 04-08-77 because the filter was lost C41 for the week of 04-15-77 because the filter was lost C47 for the week of 04-15-77 because the filter was lost C41 for the week of 09-23-77 because of loss in the U.S. Mail All other weekly samples were collected and analyzed. There is no LLD specification for this pathway. Sample Station C41 is the critical station in this pathway and no simple had activity greater than 10 times the controlA station pathway. value.

statistical Thereof analysis was theno preoperational operational data data (in pCi/m for tgis ) is as follows:

Mean 95 percentile Critical Sample Station .047 .139 Control Sample Station .085 .168 All Sample Stations .075 .164 Most of the operational activity is due to fallout from a' Chinese weapons test. This activity was seen equally by critical and control stations.

Quarterly Gamma Analysis The summary for the gama analysis of quarterly composites is in Table III-3. All quarterly composite samples were collected and analyzed and

, all had LLD's equal to or less than those required. There are no ritical stations for this type of analysis and no samples had activities greater than 10 times the control station value.

The statistical evaluation of these analyses is in Table III-4. The operational 95 percentile value of almost all nuclides is about equal

to or less than the preoperational value. The two exceptions are Zr-95 i and K-40. But since all other nuclides have statistics similar to the preoperational numbers, it is likely that some preoperational data reported

.. was less than the minimum detectable activity.

.g_ - -

Quarterly Sr-89 and 90 Analysis The summary for the Sr-89 and .90 analysis of quarterly composites is in Table III-5. The quarterly composite for the third quarter from

. San.,le Stations C41 and C47 was lost due to a laboratory accident.

, All other quarterly composites were collected and analyzed and all

. had LLD's equal to or less than those required. There are no critical

, stations t'or this type of analysis and no samples had activities greater than 10 times the control station value.

There are no preoperational results reported for this type of analysis, therefore no cqm data (in pCi/F )parison are as can be made. The statistics of the operational follows:

Median Mean 95 Percentile Value Value Value Sr-89 .005 .009 .025 Sr-90 .001 .002 .005

PRECIPITATION PATHWAY The State has the responsibility to collect and analyze precipitation samples. There are no additional stations for the pathway.

Monthly Tritium Analysis The summary for the tritium analysis of the monthly precipitation sample

. is in Table III-6. Due to insufficient rainfall, samples were not collected at C04 for July, at C26 for November, and at C40 for June and November. All other samples were collected and analyzed and.all had LLD's equal to or less than those required. There are no critical stations for this type of analysis and no sample had any detectable activity. The preoperational analyses also had no detectable activity.

Monthly Gamma Analysis The summary for the gamma analysis of the monthly samples is in Table III-7. Due to insufficient rainfall the samples listed in the Monthly Tritium Analysis section were not collected. All other monthly samples were collected and analyzed and all had LLD's equal to or less than those required. There are no critical stations for this type of analysis and no sample had any datectable activity. The pre-operational analyses also had no detectable activity.

SEAWATER PATHWAY The University has the responsibility to collect and analyze seawater

[ samples. There are no additional ststions for this pathway.

', Monthly Gamma Analysis

,' The summary for the gamma analysis of monthly samples is in Table III-8. The monthly samples were not collected at C01 for March, at C09 for March, at Cl3 for March, at C14H for April and at C14M for April. All other samples were collected and analyzed and all but three nuclides had annual average LLD's equal to or less than those required.

The three nuclides were Th-232 (averaged 22 pci/kg), I-131 (averaged 12 pC1/kg) and Zn-65 (averaged 23 pCi/kg). As can be seen, these averages are only slightly above the required LLD's and longer count times will bring these averages down in 1978. Sample Station C14G is the critical station in this pathway and no sample had activity greater than 10 times the control station value. A statistical evaluation of the operational data and a comparison with the pre-operational data is presented in Table III-9. The operational data compares favorably with the preoperational data except for perhaps Th-232.

Crystal River Unit 3 did not release any Th-232 in its liquid releases so the differences may be attributable to the preoperation statistics.

Quarterly Sr-89 & 90 Analysis The summary for the Sr-89 & 90 analysis of quarterly composites is in Table III-10. The quarterly composites for the first quarter from Sample Stations C01, C09 and Cl3 were lost due to a laboratory '

accident. All other quarterly composites were collected and analyze and the annual average LLD for Sr-89 was equal to or less than that required. The annual average LLD for Sr-90 was 3 pCi/kg (vs the required 2 pCi/kg) because of low composite volumes for the third quarter. There are no critical stations for this type of analysis and r.o sample had activities greater than 10 times the control station value.

There were no reported preoperational results and the only detectable operational activity was 12 pCi/kg of Sr-89 for the first quarter at C14H. During the first quarter of 1977, Crystal River Unit 3 released less than 11 pCi of Sr-89. Therefore, the resul? is not considered valid.

Quarterly Tritium Analysis

.' The summary for the tritium analysis of quarterly composites is in

. Table III-ll. All quarterly composites were collected and analyzed

, and all had LLD's that were equal to or less than those required. There are no critical stations for this type of analysis and no sample had

. activity greater than 10 times the control station value.

A com arison of the preoperational and operational analysis (in pCi/t is as follows:

Preoperational Median Value = 71 ,

Preoperational 95 Percentile Value = 87 Operational Mean Value = 497 Operational Median Value = 510 Operational 95 Percentile Value = 626 In the first quarter, Crystal River Unit 3 released 3.74 curies of tritium in its liquid releases. In the remaining three quarters, 28.9, 47.5, and 85.4 curies respectively were released with no tritium being detected at any sample station. It is possible that the first quarter samples were collected just after a liquid release (although this would not explain the tritium activity at Sample Station C09) and the samples for the next three quarters weren't, but this is not probable.

Since the preoperational values are below the minimum detectable activity of 320 pCi/t, it is more probable that spurious activity findings were combined with findings of less than the MDA and~thus hidden in the vast' amount of preoperational data.

POTABLE WATER PATHWAY The University has the responsibility to collect and analyze potable

. water samples. There are no additional stations for this pathway.

Quarterly Gamma Analysis The summary for the ganna analysis of quarterly samples is in Table III-16.

All samples were collected and analyzed and six of the eight nuclides had annual average LLD's squal to or less than those required. The annual average LLD for 7.-131 was high because of high first quarter LLD's. Corrective act';n resulted in an average LLD for the final three quarters of 11 pCi/kg (10 pCi/kg is required). The high annual average LLD for Zn-65 was the result of high first quarter LLD's and a high third quarter LLD for Sample Station C07 because of insufficient sample volume. The averago LLD for the remaining samples was equal to that required. There are no critical stations for this type of analysis.

The only samples that had any activity was for the second quarter at Sample Stations C10 and C18. The activity was equal to or less than the preoperational activity levels.

Quarterly Tritium Analysis The summary for the tritium analysis of the quarterly samples is in Table III-17. The third quarter sample for Sample Station C07 was lost due to a laboratory accident. All other samples were collected and

. analyzed and all had LLD's equal to or less than those required. There are no critical stations for this type of analysis and Sample Station-C18 had the only detectable activi:y. It was 470 pCi/t during the first quarter. All preoperational samples had an average activity of less than 320 pCi/t. There was, therefore, probably no increase in activity over the preoperational levels.

SHORELINE EXTERNAL SEDIMENT PATHWAY

, The University has the responsibility to collect and analyze shoreline external sediment samples. There are no additional stations for this pathway.

. Semiannual Gamma Analysis The summary for the gamma analysis of the semiannual samples is in Table III-18. Due to extremely hard shoreline sediment, samples were not collected for the first half at Sample Stations C01, Cl4H and C14M. All other samples were collected and analyzed and the annual average LLD's for eight of the eleven nuclides were equal to or less than those required. The annual average LLD for I-131 was 11 pCi/kg (10 pCi/kg is required) and for Mn-54, it was 14 pCi/kg (10 pCi/kg is required. Corrective action including longer count times reduced the LLD's in the second half from those in the first half and the annual average LLD's for 1978 should be equal to or less than those required. The annual average LLD of 46 pCi/kg for Zn-65 is very large .

compared to the required LLD of 20 pCi/kg. However, the Zn-65 gamma l is at about the same energy as the average gamma from the Compton effect of l K-40. When there is K-40 activity in a sample, it will influence the Zn-65 LLD even though there may be no Zn-65 activity. The critical ,

stations for this analysis are Sample Stations Cl4H, Cl4M and C14G.

A statistical evaluation of the operational data and a comparison with the preoperational data is presented in Table III-19.

The operational data is equal to or less than the preoperational data for almost every nuclide. The lack of more operational data prevents a more thorough comparison. Also, the control station data is very similar to the critical station data. The plant, therefore, has had no detectable effect on this pathway.

Semiannual Sr-90 Analysis The summary for the Sr-90 analysis of the semiannual samples is in l Table III-20. Due to extremely hard snoreline sediment, samples were not collected for the first half at Sample Stations C01, C14H, and Cl4M. 1 All other samples were collected and analyzed and all had LLD's equal to or less than that required. There are no critical sample stations in the l pathway. There was no preoperational data for this analysis and all

~

i operational analyses resulted in nondetectable activity.

Semiannual Gama Analysis The sunnary for the gamma analysis of semiannual samples is in Table III-21. All samples were collected and analyzed and all nuclides but K-40 had annual average LLD's greater than those required. Corrective actions including increased sample sizes and longer count times should bring all annual average LLD's in line with the requirements in 1978.

There are no critical stations in this analysis and no samples had activity greater than 10 times the control station value. A statistical evalua-tion of the operational data and a comparison with the preoperation data ,

is presented in Table III-22.

The operational values are very close to the preoperational values but the lack of more data prevents a more rigourous statistical comparison.

Semiannual Sr-89 and 90 Analysis The summary for the Sr-89 and 90 analysis of semiannual samples is in Table III-23. All samples were collected and analyzed and both annual average LLD's were equal to or less than those required. There are no critical sample stations for this analysis. There was no preoperational data for this analysis and all operatiional analyses resulted in nondetectable activity.

- Semiannual Gamma Analysis The summary for the gamma analysis of the edible portion of semiannual samples is in Table III-24. The sample for the first half at C30 was not collected due to the unsuccessful attempts at entrapment. All other samples were collected and analyzed. Even though nine of the eleven nuclides had annual average LLD's greater than those required, the second '

half LLD's were less than the first half LLD's due to longer count times.

Even longer count times and increased sample size should bring all annual average LLD's in line with the requirement in 1978. Sample Station C29 is the critical station in this pathway. A statistical evaluation of the operational data and a comparison with the preoperational data is presented in Table III-25.

Even though there is a lack of enough samples to allow for a useful statistical evaluation, the operational results do tend to be similar to the preoperational results.

. The University has the responsibility to collect and analyze oysters.

There are no additional stations in this pathway.

Semiannual Gamma Analysis The summary for the gamma analysis of the edible portion of semiannual samples is in Table III-30. All samples were collected and analyzed.

Even though eight of the ten ncclides had annual average LLD's greater than those required, longer count times and larg r samples should bring all annual average LLD's in line with the requirements in 1978. There are no critical stations in this pathway. A statistical evaluation of the operational data and a comparison with the preoperational data is presented in Table III-31.

Even though there is a lack of enough samples to allow for a useful statistical evaluation, the operational results do tend to be similar to the preoperational results.

INGESTION SHRIMP PATHWAY I The Unviersity has the responsibility to collect and analyze shrimp. There are no additional stations in this pathway.

- Semiannual Gamma Analysis The summary for the gamma analysis of the semiannual samples is in Table III-32. The sample for the second half at C27 was not available from the Ralston Purina Research Facility. The other sample was collected and analyzed. Even though eight of the ten nuclides had LLD's greater than those required, longer count times and larger sample size should bring all annual average LLD's in line with the requirements in 1978.

There are no critical stations ir. this pathway.

One sample lacks the statistics for an evaluation of the operational data or a rigorous comparison with the preoperational data. The activity found in the shrimp does however correspond to that found in the preoperational shrimp. It should be noted that discharge canal water was not used for shrimp raising in 1977.

INGESTION MILK PATHWAY The University has the responsibility to collect and analyze milk. There are no additional stations in this pathway.

Monthly Gansna Analysis

, The summary for the gama analysis of monthly samples is in Table III-33. The samples for January through May at Sample Stations C47 and C49 were not collected due to the unavailability of milk at the Critical 4 Sample Station. The samples for October through December at Sample Station C49 were not collected due to the unavailability of milk. All other samples were collected and analyzed and all had annual average LLD's equal to or less than those required except for T-131. The annual average LLD was 11 pci/kg and the required LLD is 10 pCi/kg. The greater than required LLD is due to the reduced sample volume at the critical sample station (a private farm). All efforts will be made to collect the needed quantity of milk in the future to assure LLD's equal to or less than those required. Sample Station C49 is the critical station in this pathway and is located at 4.5 miles from the plant in the east sector.

A statistical evaluation of.the operational data and a comparison with the preoperational data is presented in Table III-34.

While there are not enough samples to develop meaningful statistics, the large increase in Cs-137 should ,be addressed. Very small amounts of Cs-137 have been released from the plant during 1977, the initial year of operation. Cesium-134 has also been re!aased from the plant and reacts similarly to Cs-137 to the environment. Tht: absence of detectable Cs-134 in the milk (which is made only by nuclear power plants and not by weapons tests) leads to the conclusion the the Cs-137 did not come from the plant.

Weapons acts by the Peoples Republic of China in the Fall of 1976 and the Fall of 1977 resulted in clouds of radioactive fallout traversing the United States. It was these clouds that probably deposited the Cs-137 in the cow pasture which was susequently detected in the milk samples.

The other nuclides yielded results similar to those determined during the preoperational study.

Monthly Sr-89 and 90 Analysis The sumary for the Sr-89 and 90 analysis of monthly samples is in Table III-35. The samples for January through May at Sample Stations C47 and C49 were not collected due tc the unavailability of milk at the Critical Sample Station. The samples for October through December at Sample Station C47 ' vere not collected due to the unavailability of milk. All other samples were collected and analyzed and all had annual average LLD's equal to or less than those required. There are no critical sample stations for

. this analysis. There was no preoperational data for this analysis and all operational analyses resulted in nondetectable activity.

INGESTION ANIMAL PATHWAY

, The University has the responsibility to collect and analyze small terrestrial animals. There are no additional stations in this pathway.

Semiannual Gamna Anaysis The summary for the gamma analysis of the semiannual samples is in Table III-36. All samples were collected a'nd analyzed. Even though eight of the eleven nuclides had annual average LLD's greater than those required, longer count time and increased sample size should lead to annual average LLD's in 1978 that are equal to or less than those required. Longer count times did decrease the LLD's for the second half samples as compared to those of the first half samples. There are no critical sample stations for this pathway. A statistical evaluation of the operational data and a comparison with the preoperational data is presented in Table III-37.

The operational results compare favorably with the preoperational results except for perhaps Cs-137. But again, this came from weapons testing and not the plant.

FOOD CHAIN (SOIL) PATHWAY The University has the responsibility to ecliect and analyze soil samples.

There are no additional stations in this pathway.

Annual Gamma Analysis The summary for the gamma analysis of the annual samples is in Table III-42.

All samples were collected and analyzed. Five of the ten nuclides analyzed had annual average LLD's greater than those required. Four of these five LLD's were excessive by only a few pCi/kg a piece. The fifth, Zn-65, is high because of apparent Zn-65 activity (see Shoreline External Sediment Pathway, Semiannual Gamma Analysis). Longer count times should lead to all annual average LLD's being equal to or less than those required. A statistical evaluation of the operational data and a comparison with the preoperational data is presented in Table III-43.

The operational results are almost identical to the preoperational results.

Thus, the plant has not increased the amount of deposited radioactive material.

FOOD CHAIN (GREEN LEAFY VEGETABLES) PATHWAY

. The University has the responsibility to collect and analyze the green leafy vegetable samples. There are no additional stations in this pathway.

Semiannual Gamma Analysis The summary for the gamma analysis of the semiannual samples is in Table III-47. Samples for the first half were not collected due to the sampling of a milk cow that was within five mile ~s of the plant. Samples for the second half were collected when the milk cow was no longer available. The LLD's for eight of the ten nuclides in the sample were i

greater than those required. Larger sample volures and longer count times should bring all LLD's to equal to or less than those required.

The critical station for this pathway (Sample Station C49) is in the east sector at 4.5 miles from the plant. There is no preoperational data for this pathway. A statistical evaluation of the operational data is presented in Table III-48. However, a comparison between the critical and control stations would not be valid because of the single sample taken.

Semiannual Sr-90 Analysis The summary for the Sr-90 analysis of semiannual samples is in Table III-49. Samples for the first half were not collected due to the sampling of a milk cow that was within five miles of the plant. Samples for the second half were collected when the milk cow was no longer available. All LLD's were equal to or less than those required. There is no critical station for this anaTysis. There was no preoperational data for this analysis and all operational analyses resulted in nondetectable activity.

IV EXTERNAL RADIATION The External Radiation portion of the Radiological Environmental Monitoring

Program (Specification 3.2.3) is split between the University and the State (See Table I-1). The University also has a TLD at Sample Station C47 and the State has additional TLD's at Sample Stations

C04, C40, and C46. The summaries for the University's data is in Table IV-1 ar for the State's data in Table IV-2. Because of vandalism, tr _ University's TLD's at Sample Stations C14M and C47 were lost. No other TLD's were lost during the report period.

Table IV-3 presents a statistical summary of all data. The data from all TLD stations compares very well with the preoperational data.

Additionally, the critical stations and the control stations of the University also compare very well. However, because the University and the State use different types of TLD's, it is necessary to report their results separately. The pcoling of the results may lead to erroneous conclusions.

Historically, the University has used a LiF-type of dosimeter while the State has employed a CaF-type of TLD. The advantages and disadvantages of both types are well documented and an unsuccessful attempt was even made to correlate the two TLD types at the Crystal River Site (EPA 520/5-73-006 and ORP/EERF 73-1). In general, the LiF TLD gives a more constant response to radiation over the energy spectrum where the CaF TLD can respond to radiation in the environment in a much shorter time. As illustrated in Table IV-3, the CaF TLD's give a consistently

( lower radiation reading than do the LiF TLD's. This allows comparisons lonly to the data of similar TLD's. It also gives a rough cross check on ,

both types of TLD's to insure that neither type is in g'ross error of the actual environmental external radiation exposure.
