1.2 MAXIMUM PERMISSIBLE CONCENTRATIONS iA)

\_/ The MPC values used in. determining allowable liquid radwaste release rates and concentrations for principal gamma emitters, I-131, tritium, St-89, Sr-90 and Fe-55 are taken from 10CFR Part 20, Appendix B, Table II, Column 2.

For dissolved or entrained noble gases in liquid radwaste, the MPC is taken from Technical Specification 3.15.1.1 (Unit I) and 3.11.1.1 (Unit' II) as 2.0E-04 uCi/ml.

For gross alpha in liquid radwaste, the MPC is taken from 10CFR Part 20, Appendix B, Note 2.b as 3.0E-08 uCi/ml.

Further for all the above radionuclides or categories of radioactivity, the overall MPC fraction is determined in accordance with 10 CFR Part 20, Appendix B, Note 1.

The method whereby the MPC fraction is used to determine release rates and liquid radwaste effluent radiation monitor setpoints is described in Section 1.3 of this report.

l.3 MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY Prior to release of any tank containing liquid radwaste, and following the required recirculation, samples are collected and analyzed in accordance with Technical Specification Tables 4.15.1-1 (Unit I) and 4.11.1-1 (Unit II). A sample from each tank planned for release is analyzed for principal gamma emitters, I-131, and dissolved and entrained noble gases by gamma spectrometry. Monthly and quarterly composites are prepared for analysis by extracting aliquots from each sample taken from tanks which are released. Liquid radwaste sample analyses are

, performed as follows:

1 Measurement Frequency Method

1. Gamma Isotopic Each Batch Gamma spectroscopy with computerized data reduction i

2. Dissolved o r' Each Batch Gamma spectroscopy i \

Entrained with computerized

- Noble Cases data reduction 4

Measurement Frequency Method

3. Tritium Monthly Distillation and

\_ - Composite liquid scintillation counting

4. Gross Alpha Monthly Gas Flow Proportional Composite counting

5. Sr-89 and Sr-90 Quarterly Chemical separation and Composite gas flow proportional counting

6. Fe-55 Quarterly Chemical separation and Composite low energy photon detector.

Gamma isotopic measurements are performed in-house in the radiochemistry lab using germanium spectrometry.

Three germanium detectors are available a 10%

efficient Ge(Li) detector and two 15% efficient intrinsic germanium detectors, with 2.0 FWHM resolution and housed in 4 inch-thick lead shields. A one-liter liquid radwaste sample is poured into a Marinelli beaker in preparation for a 2000-3000 second count. A peak search of the resulting gamma ray spectrum is performed by the computer system. Energy Q( ,) and net count data for all significant peaks are determined, and quantitative reduction or LLD calculations are performed for the nuclides specified in Table Notation e of Technical Specification Tables 4.15.1-1 (Unit 1) and 4.11.1-1 (Unit 2) : Mn-54, F-59, Co-58, Co-60, 2n-65, Mo-99, Cs-134, Cs-137, Ce-141 and Ce-144. The quantitative calculations include corrections for counting time, decay time, sample volume, sample geometry, detector efficiency, baseline counts, and branching ratio. LLD calculations, L

including the above corrections, are made based on the counts in two standard deviations of the baseline count at the location on the spectrum where a peak for that radionuclide would be located if present.

l l

The radionuclide concentrations determined by gamma spectroscopic analysis of a sample taken from a tank planned for release and the most current sample analysis results available for tritium, gross alpha, Sr-89, Sr-90, and Fe-55 are used along with the corresponding MPC values to determino an MPC fraction for the tank planned for release. This MFC fraction i is then used, with appropriate safety factors, along l with the expected dilution stream flow to calculate a

() maximum permissible release rate and a liquid effluent l

monitor setpoint. The monitor setpoint is calculated to assure that the limits of Technical Specifications 3.15.1.1 (Unit 1) or 3.11.1.1 (Unit 2) are not exceeded.

l.

I l

l A nonitor reading in excess of the calculated setpoint therefore results in an automatic termination of the liquid radwaste discharge.

Liquid effluent discharge is also automatically I'~ terminated if the dilution stream flow rate falls

(_ /D below the dilution flow rate used in the setpoint calculations and established as a setpoint on the j dilution stream flow monitor. J Radionuclide concentrations, safety factors, dilution stream flow rate, and liquid effluent radiation monitor calibration factor are entered into the computer and a prerelease printout is generated. If the release is not permissible appropriate warnings will be included on the prerelease printout. If the release is permissible it is-approved by the Chemistry Foreman on duty. The pertinent information is transferred manually from the prerelease printout to a one-page release permit which is forwarded to Radwaste Operations. When the release is completed the release permit is returned from Radwaste Operations with actual release data included. This data is input to the computer and a postrelease printout is generated. The postrelease printout contains actual release rates, actual release concentrations and quantities, actual dilution flow and calculated doses to an individual.

l l.4 LIQUID EFFLUENT RELEASE DATA Regulatory Guide 1.21 Tables 2A and 2B are found in this report as Table 1-2a for Unit 1 and Table 1-2b for Unit 2; and Table 1-3a for Unit 1 and 1-3b for Unit 2.

The values for the four categories of Tables 1-2a l

. and 1-2b are calculated and the Tables completed as follows:

1. Fission and activation products - The total release values (not including tritium, gases, alpha) are comprised of the sum of the measured individual radionuclide activities. This sum is for each batch released to the river for the respective t

quartor. Porcont of cpplicablo limit is datorminod froo a nixod nuclido MPC fraction I calculation. The average concentration for  !

each nuclide over all released batches is I divided by the corresponding individual MPC j-s)

( value. The sum over all nuclides of the Ci/MPCi ratios times 100 is the percent of applicable limit for effluent releases during the quarter.

2. Tritium - The measured tritium concentrations in the monthly composite samples are used to calculate the total release and average diluted concentration during each period. Average diluted concentration divided by the MPC limit, 3.0E-03 uCi/ml, is converted to percent to give the percent of applicable limit.

3. Dissolved and entrained gases -

Concentrations of dissolved and entrained gases in liquid effluents are measured on each batch by germanium spectroscopy on a one liter sample from each liquid radwaste batch. The average concentration of dissolved or entrained nobles gases for all released batches is divided by the MPC value stated in Technical Specifications 3.15.1.1 and 3.11.1.1 (2.0E-04 uCi/ml) to determine the MPC fraction. The result x100 is the pe,rcent of applicable limit for noble gases N in liquid effluent releases during the quarter. Iodine radionuclides in any form are also determined during the isotopic analysis for each batch, therefore a separate analysis for possible gaseous forms is not performed because it would not provide additional information.

4. Gross alpha radioactivity - The measured gross alpha concentrations in the monthly composite samples are used to calculate the total release of alpha radioactivity.

Other data pertinent to batch releases of radioactive liquid effluent from both units is as follows:

Number of batch releases: 805 Total time period for batch releases: 87,722 minutes Maximum time period for a batch release: 293 minutes 2

~

Doses to an individual, due to radioactivity in liquid effluent, were calculated in accordance with Technical Specifications 3/4.15.1.2 (Unit 1) and 3/4.11.1.2 (Unit 2) using the methodology presented in the Plant Edwin I. Hatch Offsite Dose Calculation Manual. As required by the above Technical Specifications, doses were calculated separately for Unit 1 and Unit 2.

Results are presented in Table 1-4a for Unit 1 and Table 1-4b for Unit 2.

1.6 ABNORMAL RELEASES Technical Specifications 3.15.1.1 (Unit 1) and 3.11.1.1 (Unit 2) state in part that if concentration of radioactive material in liquid effluents released from the site to unrestricted areas exceeds the concentration limits stated within, notification, including a discussion of causes and corrective actions taken, must be f)

\'

provided to the Commission in the next Semi-annual Effluent Release Report. Further, Regulatory Guide 1.21 states that the total curies of radioactive materials released as a result of abormal releases should be included.

On November,3, 1985, during the release of Chemical Waste Sample Tank B (Unit 2) to the Altamaha River, the concentration of radioactive material entering the river exceeded Technical Specification 3.11.1.1 limits for a period of one minute. A total of 58 gallons of liquid containing 70.6 microcuries was released.

The cause of the abnormal release was personnel error in that the chemistry technician and the lab foreman who approved the discharge permit prior to release failed to recognize that the i specified tank discharge rate was greater than the maximum permissible discharge rate calculated for the planned release. The liquid radwaste i effluent radiation monitor tripped after one j minute of discharge and terminated the release.

Additional training was given to the chemistry i staff concerning liquid radwaste discharge s,) permits and the significance of information contained in the permits.

l

\

Waste gas release at Plant Hatch is confined to four paths: main stack (also called the offgas vent) , Unit 1 reactor building vent; Unit 2 reactor building vent, and the recombiner building vent. Each of these four paths is continuously monitored for gaseous radioactivity. Each is equipped with an integrating-type sample collection device for collecting particulates and iodines. Sample collection is in accordance with Technical Specification Tables 4.15.2-1 (Unit 1) and 4.11.2-1 (Unit 2) . Unless required more frequently under certain circumstances specified in Table Notations to the abovementioned tables,-

samples are collected as follows:

1. Noble gas samples are collected by grab sampling monthly.

2. Tritium samples are collected by grab sampling monthly.

3. Radioiodine samples are collected by pulling

'j the sample stream through a charcoal cartridge over a 7-day period.

)

4. Particulates are collected by pulling the sample stream through a particulate filter over a 7-day period.

5. The 7-day particulate filters above are analyzed for gross alpha activity.

6. Quarterly composite samples are prepared from the particulate filters collected over i

the previous quarter and the quarterly composite sample is analyzed for Sr-89 and i

Sr-90.

Sample analyses results and release flow rates from the four release points form the basis for calculating released quantities of radionuclide-specific radioactivity, dose rates associated with gaseous releases, and cumulative doses for the current quarter and year. This task is normally performed with computer assistance.

O 4

The noblo goo greb neaplo analycio results are used along with, maximum expected release flow rates from each of the four vents to calculate monitor setpoints for the gaseous effluent

(~}/

(, monitors serving the four release points, to assure that the limits of Technical Specifications 3.15.2.1.a (Unit 1) or 3.11.2.1.6 (Unit 2) are not exceeded. Calculation of ,

monitor setpoints is described in the Plant Hatch.

ODCM.

With each release pe$1od released radioactivity, dose rates, and cunulative doses are calculated.

Cumulative dose results are tabulated along with percent of Technical Specification limits (3.15.2.2 and 3.15.2.3,(Unit'l); 3.11.2.2 and 3.11.2.3 (Unit 2) for each release, for the current quarter and year.

After each calendar quarter (13 weeks) a summary of waste gas releases from the four vents is compiled for preparation of the Semiannual Effluent Release Report required by' Technical Specifications 6.9.1.8 and 6.9.1.9 and described in NRC Regulatory Guide 1.21.

The methods for determining released quantities of, radioactivity, dose' rates and cumulative doses are as follows:

l. FISSION AND ACTIVATION GAS The radionuclide-specific' releases radioactivity is determined from sample analyses results

collected as described above and average release flow rates over the period represented by the' collected sample.

Instantaneous dose rates are calculated (with 3 computer assistance) due to noble gases and due to radioiodines, tritium, and particulates.

Calculated dose rates are compared to the dose-l rate limits specified in 3.15.2.1.a (Unit 1) and 3.11.2.1.a (Unit 2) for noble gases; and 3.15.2.1.b (Unit 1) and 3.11.2.1.b (Unit 2) for radioiodine, tritium, and particulates. Dose rate calculation methodology is presented in the Plant Hatch ODCM.

O l (

l

' s ,3 I( A (4, Beta and gamma air doses due to noble gases are y ,_ ' calculated for the location in the unrestricted area with the potential for the highest exposure f

t due to gaseous releases. Air doses are calculated for each release period and cumulative totals are kept for each unit for the current calendar quarter and year. Cumulative air doses are compared to the dose limits specified in Technical Specifications 3.15.2.2 (Unit 1) and 3.11.2.2 (Unit 2) . Current percent of tech spec limits are shown on the printout for each release period. Air dose calculation methodology is presented in the Plant Hatch ODCM.

2. RADIOIODINE, TRITIUM, AND PARTICULATE RELEASES Released quantities of radioiodines are determined from the weekly samples and release flow rates for the four release points.

Radioiodine concentrations are determined by gamma spectroscopy.

Released quantities of particulates are determined from the weekly (filter) samples and release flow rates for the four release points.

Gamma spectroscopy is used to quantify concentrations of principal gamma emitters.

(\)

After each calendar month the particulate filters from each vent are combined, fused, and strontium separation is made. Since sample flows and vent flows are almost constant over each monthly period the filters from each vent can be dissolved together. Decay corrections are made back to the middle of the quarterly collection period. Where significant Sr-89 or St-90 is not detected, LLD's are calculated. Strontium concentrations are input to the composite file of the computer to be used in release, dose rate and individual dose calculations.

Tritium samples are obtained monthly from each vent by passing the sample stream from a cold trap immersed in a liquid nitrogen or an acetone and ice mixture. The grams of water vapor / cubic foot gas is measured upstream of the cold trap in order to alleviate the difficulties in determining water vapor collection efficiencies.

The tritium samples are analyzed by an independent laboratory and results are furnished in uCi/ml of water. The tritium concentration in water is converted to tritium concentration in air and this value is input into the composite file of the computer to be used in release, dose C) rate, and individual dose calculations.

s.

Dose rates due to radioiodine, tritium, and fs particulates are calculated for a hypothetical

.( ) child, exposed to the inhalation pathway, at the location in the unrestricted area where the potential dose rate is expected to be the highest. Dose rates are calculated for each release point, for each release period, and the total dose rate from all four release points are compared to the dose rate limits specified in Technical Specifications 3.15.2.1.b (Unit 1) or 3.11.2.1.b (Unit 2) .

Individual doses due to radioiodine, tritium, and particulates are calculated for the critical receptor, which for Plant Hatch is an infant exposed to tne grass-cow-milk, inhalation, and ground-plane pathways. Individual doses are calculated for each release pericd and cumulative totals are kept for each unit for the current calendar quarter and year. Cumulative individual doses are compared to the dose limits specified in Technical Specifications 3.15.2.3 (Unit 1) and 3.11.2.3 (Unit 2) . Current percent of tech spec limits are shown on the printout for each release period.

[ T 3. GROSS ALPHA RELEASE

.V The gross alpha release 's i computed each month by counting the particulate filters each week for gross alpha activity in a proportional counter.

The four or five weeks numbers are then recorded i on a data sheet and the activity is summed at the end of the month. This concentration is input to the composite file of the computer and is used

[ for release calculations.

4. ERROR ESTIMATES Regulatory Guide 1.21 requires that estimated total error in analysis techniques be reported.

These estimates are required for the total fission and activation gas release, total I-131 release, total particulates with half-lives greater than 8-day release, and total tritium release.

l l

l l

"The total or maximum error associated with the effluent measurement will include the cumulative errors resulting from the total operation of sampling and measurement. Because it may be very

("N

( ,) difficult to assign error terms for each parameter affecting the final measurement, detailed statistical evaluation of error are not suggested. The objective should be to obtain an overall estimate of the error associated with measurements of radioactive materials released in liquid and gaseous effluents and solid waste."

Estimated errors are based on errors in counting equipment calibration, counting statistics, vent flow rates, vent sample flow rates, non-steady release rates, chemical yield factors, and sample losses for such items as charcoal cartridges.

1 2.3 GASEOUS EFFLUENT RELEASE DATA Regulatory Guide 1.21 Tables lA, 1B, and 1C are found in this report as Tables 2-2a-c, 2-3a-c, and 2-4a-c.

Data are presented on a quarterly basis as required by Regulatory Guide 1.21.

To complete Vables 2-2a-c, total release for each of the four categories (fission and activation gases; iodines; particulates; and tritium) was divided by the number of seconds in the quarter to obtain a release rate in uCi/second for each category.

However, the applicable Technical Specification limits are not in terms of release rate in uCi/second but in g3 terms of done rate in mrem / year, as presented in

( ) Technical Specifications 3.15.2.1 (Unit 1) and 3.11.2.1 (Unit 2) . Noble gases are limited as specified in 3.15.2.1.a and 3.ll.2.1.a. The other three categories (tritium, radioiodines, and particulates) are limited as a group as specified in 3.15.2.1.b and 3.11.2.1.b. Further the limits specified in Technical Specifications 3.15.2.1 and 3.11.2.1 are site limits, not unit limits. Dose rates due to noble gas releases and due to radioiodine, tritium, and particulates are presented in Table 2-5 along with percent of technical specification limits.

5. METEOROLOGY

_ In accordance with Technical Specification 6.9.1.9, the annual summary of meteorological data collected at Plant Hatch over 1985 is presented in this section.

5.1 REVIEW OF 1985 DATA The second year of Plant Hatch meteorological data was collected on the new level primary tower during 1985.

The wind speed and direction data of all three levels (10m, 60m, 100m) are shown in Attachments 5-4 through 5-6. The wind roses agree quite well between levels.

They all have a predominant wind direction of northeast with a secondary peak of a westerly wind direction. This agreement is prevalent in the quarterly wind roses as well, particularly during the third and fourth qu6rters with a high percentage of northeast winds.

The wind directions generally agree with previous years when the west and northeast winds have been dominant. However, in 1984 the winds were more from the southwest. This slight shift is due to normal year to year climatic variations in wind direction.

The high percentage of northeast winds may have caused by the large number of storms moving up the east coast

, during the fall.

The ambient and dew point temperature date (10m level) for 1985 are shown in Attachment 5-7. The temperatures were normal when compared with previous years. They reflect the fact that the temperatures were well above average for the month of June. As with the 1984 data, the summertime temperatures are a few degrees lower than the average for the early 1980's. Since data collection began on the new meteorological tower in 1982, this has occurred each year.

The joint frequency tables of wind speed and direction versus delta temperature (Attachments 5-1 through 5-3) continue to show some differences with previous years tables. The elevation difference between the new and old meteorological towers 164 feet versus 117 feet is responsible for the shift from unstable toward neutral conditions.

l

J The following table shows the latest 5 year stability classifications.

i The total precipitation for 1985 was about 28 inches. As in the past, this is well below local climatic averages of about 45 inches. The 28 inches is close to the Hatch average precipitation totals of previous j years.
