1.1. REGULA10RY LIMITS

1. The concentration of radioactive caterials released in liquid wastes from all reactors at the site shall net exceed the values specified in 10 CFR Part 20, Appendix 0, Table 11, Colua.n 2, for unrestricted area.

2. The release rate of radioactive materials in liquid wastes, excluding tritium and dissolved gases, shall not exceed 10 Ci/ reactor / calendar quarter.

3. The release rate of radioactive materials in liquid wastes, -

excluding tritium and dissol','ed gases, shall not exceed 20 Ci/ reactor in any 12 consecutive months.

4. During release of radioactive wastes, the effluent control monitor shall be set to alarm and to initiate the automatic closur.e of the waste discharga valve prior to exceeding the limits specified in 1. above.

5. The operability of the automatic isolation valve in the liquid radioactive waste discharge line shall be demonst-rated qu1rterly.

6. The equipment installed in the liquid radioactive waste system shall be maintained and shall be oparated to process radioactive liquid wastes prior to their discharge when the projected cumulative release rate w~ill excced 1.25 Ci/ reactor /

. calendar quarter, excluding tritium and dissolved gases.

7. The makimum radicactivity to be contained in any liquid radwaste t. ink that can be discharged directly to the environs shall not exceed 10 Ci, excluding tritium and dissolved gases. , .

8.' When the release' rate of radioactiYe materials in liquid wastes, excluding tritium and dissolved gases, exceeds 2.5 Ci/ reactor / calendar quarter, the licensee shall maPe an in-vestigation to identify the causes of such release rates, define and initiate a program of action to reduce such release rates to the design objective levels end report these actions to the Conaission within 30 days from the end of the quarter during which the release occurred.

l.2. l'AXIMUM PERMISSIBLE CONCENTRATI0"5 The IIPC values used in.deternining allowable liquid radwaste release concentrations are taken frem 10 CFR Part 20, Appendix 8. Table II, Colua.n 2. Release rate and dilution ratio for each batch are de-ternined by a mixed nuclide W C calculation cerfonned before the re .

lease of the batch. To facilitate the measurements and calculations, the nuclides of Column 2 which can be produced in a fission reactor have been grouxd according to MPC value and type of radiation as sho.n in Figure 1-1.

(1)

The concentration of each of the 29 gamna emitting nuelides specifically noted in Figure 1-1 is measured individually because of interest in that nuclide or because of inadequate sensitivity for the nuclide from a gross activity measurement. For any of the 29 nuclides not de tec te d in the gamma scan, the MDA limit is computed from the measured data for that sample.

Only two pure beta emitters, Sr-89 and Sr-90, have MPC values less than 9X 10-6 uCi/ml. Individual measurements are made the on proportional composite liquid radwaste samples to determine Sr-89 and Sr-90 concentration or MDA value to be applied to individual batch release calculations.

Although the MPC limit for tritium is greater than 9 X 10 - 6, a separate measurement is made for tritium since the gross beta technique does not provide an acceptable tritium measurement. A distilation and liquid scintillation counting technique is used to measure tritium concentration.

The maximum activity of gamma and beta emitting nuclides with MPC values greater than 9X 10-6 uCi/ml, except for the 29 nuclides noted above, is determined by gross gamma and gross beta Measurement sensitivity limits of approximately 2 measurements.

cpm /ml allow a null measurement to shou that the sum E (Ci/MPCi), is less than 0.1 for gamma and beta nuclides not measured directly.

The sum of the ration, I (Ci/MPCi), for alpha emitters can be shown to be less than 0.1 by a null measurement with a sensitivity limit of approximately 1 X 10 - 2 cpm /ml. Cas flow counting is used to achieve the required sensitivity of measurement.

Thus, except for ra d ionu c li de s produced in negligible quantities in a fission reaction (eg. I-125, I-129 etc.), the methods outlined above provide a means to assign a quantitatively measured or MDA value to all nuclides in Column 2. These measured and calc 21ated concentration values for each batch are used to calculate the dilution ratio, release rate, and dilution rate. prior to release of each batch. Both the concentration and release data are stored on a computer disc file. The disc file data is used to assure that quarterly and annual release limits are not exceeded. Bases used for the data of Table 1-1 are as follows:

A. Fission and activation produc ts - The total release values (not including tritium, gases, alpha) are comprised of the sum of the individual ra d ionuc li de activities and include the LLD concentration of all isotopes that were not measured but did not meet the minimum sensitivity limit as set forth in the Envircnmental Tech Specs. This num is for each batch 9 released to the river for the of applicab1" limit 1: determinod ^ n t 7 respactive "t

summed over all batches is divided by the corresponding individual MPC value. The sum over all nuclides of the Ci/MPCi ra t i on times 100 in the percent of applicable limit for effluent releases during the quarter.

B. Tritium - The measured tritium concentration in a composite sample is used to calculate the total release and average diluted concentration during each period. Average diluted concentration divided by the MPC limit, 3 X 10-- 3 uct/ml, is converted to percent to give the percent of applicable limit.

C. Dissolved and entrained gases - Concentrations of dissolved and entrained gases in liquid offluents are measured on each batch by Ge(Li) spectroscopy on a one liter sample from each liquid radwaste batch. Dissolved and entrained gases for which neasured or MDA concentrations are determined include nobic gases with half lives greater than 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months ; Xe-135, Xe-133m, Xe-133, and Kr-85. Iodine radionuclides in any form are also determined during the isotopic analysis for each batch, there fore a separate analysis for possible gaseous forms is not performed because it would not provide additional information.

A conservative release limit, the maximum sensitivity limit of 10 - 5 uC1/ml of each dissolved and entrained radionuclide as specified in Regulatory Guide 1.21, has been applied in determining the percent of applicalbo limit.

D. Alpha measurements are taken monthly from the Liquid Radvaste composite. A study was instituted in July to determine if the ratio method, as described in the E.T.S.

Table 2.1 ' footnote e could meet the LLD of 10% of the MPC value spectfled in 10 CFR part 20 Appendix B, Table II, Column 2. The lim!t of 3X 10-9 uCi/mi was never excecced tiuring the study. Below is a summary of the study findings.

1. 3 MEASUR EME!!TS A!!D APPROXIM ATIO!!S OF TOTAL R ADIO ACTIVITY.

Details of the analytical procedures for liquid radwaste analysis are contained in operating procedure IU!P-7601. The following measurements are performed as indicated:

ME A SU R EMC:!T FR EQlIE!!CY METHOD

1. Ganna Isotopic Each Batch Ge(Li) spectronotry with on-line computer.

2. Gross Gamma Each Batch 2X 2 flaI well crystal counting 3 Gross Beta Each Batch Gas flow proportional counting

4. Sr-89 Monthly Chemical separation and composite gas flow proportional counting

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

6. Tritium Monthly Distillation and liquid Composite scintillation counting

7. alpha Monthly Gas flow proportional Composite counting

8. Dissolved Gases Each Batch Ge(Li) spectrometry with on-line computer (4)

If a liquid raduaste tank cannot be reprocef.[ed, a san.nle for analysis is taken from the tank af ter the required recirculation t irse. The sample is used for ganm-ray spectroscopy, gross ganna and gro',s beta counting, and for preparat icn of a co:.;sosite sample.

lhe Ge(Li) detector systems censist of a 10", and two 15% efficiency, 2.0 FUllM resolution detectors in <i-inch thick lead shields. A one-liter raddaste liquid sanale is solidified in a furinelli beaker in prepa-ration f or a 20000000 second Ge(Li) count. A peak search of the resulting gar.na ray spectrum is performed by the on-line cc:rputer systen. Energy and net count data for all significant peaks are Je-termined, and quantitative reduction or MDA calculations are performed for the nuclidos listed in figure 1-1. lhe quantitative calcula-tions inclu& correcticas for counting tina, decay time, sample volume, sample gcometry, detector efficienc.y, baseline counts, and branching ratio. l'DA calculations, including the above corrections, are made ba',ed on the counts in two standard deviations of the baseline count at the location on the spectrum t;here a peak for that nuclide would be located if present.

The calculated radionuclide concentrations or MDA values from the gamma scan an:I fro::1 previously s tored Sr-89 and Sr-90 values are used to calculate the dilution ratio t (Ci/MPCi) and allowable release parameters.

A sarcple printout is shcain in figures 1-2 and 1-3.

The Liquid Radaaste Discharge Permit Printout is transferred item by item to the first portion cf the release pernit (Figure 1 o.) by a laboratory technician. Although the computer could printout the release permit and vill inform the technician if a batch cannot be discharged as desired, a manual transfer of calculated res ults to the release permit by the technician was implemented as moce likely to catch abnermal conditions in the data:

The liquid rantaste monitor setting is calculated by the computer based on the gross gama activity es mecsure.d in the sarrple used for laboratory analysis. A coefficient hts been determined which relatcs laboratory gress gam.ca counts to the monitor count rate. If the msnitor count rate e:'ceeds the calculated setting' during discharce, then the liquid possing through the monitor is not Pepresentative of the sanple which was analyzed in the lab. A monitor reading in excess of the cal-culated setpoint therefore results in an culcactic termination of the liquid ef fluent discharge. Liquid effluent discharge is also auto-matically terminated if the dilution flow rete falls belove the flow rate used in the computer calculation.

When the release peruit is returned from Rydaaste Operations following discharge, the discharge data is cambined vith the analysis results on the computer disc file. The disc file may be scanned to display trends in any recorded parameter, or my be summed for reparting purposes as shown in Figure 1-5.

O m ,

All other radionuclide concentration measurements are performed as indicated in the table given previously in this section and as detailed in the procedure HNP-7601. The dissolved gases calculation is performed in the Ge(Li) spectrometry system with computer data reduc tion using the Liquid Radwaste Library which includes gases.

Several comments are indicative of the success of the HNP liquid radwaste prog"am during this reporting period:

1. The total measured activity released in liquid e f fluen t for both Units was 7.34 E-3 curie for the third quarter and 1.51 E-2 curie for the fourth quarter. These alues were approximately 1/1430 for Unit 1 and 1/2832 for unit 2 for the third quarter and 1/1280 for Unit 1 and 1/1381 for Unit 2 for the fourth quarter of the allowed 10 curies per quarter per reactor.

2. The ra d wa s t e releast procedure strongly emphasized reprocessing rather than discharge of liquid radwaste.

During this report period only ?4.h% of the Itquid radwaste reaching the sample tanks was discharged; 75.6% was recycled back into both of the reactor water systems.

3 A complete isotopic scan, gross beta, and gross gamma counts and ceaputer analysis were performed prior to the release of each of the 566 discharge batches for both Units.

1.4 BATCH RELEASES Regulator" Guide 1.21 Tables 2A and 2B are found in this report as Table 1-1 and 1-2. Data is presented on a quarterly basis as per Regulatory Guide 1.21. If it is requested, a monthly tabulation will be submitted.

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

Number of batch releases: 566 Total time period for releases: 66875 minutes Maximum time period for a batch release: 227 mi nu te s Average time period for batch release: 121 minutes Minimum time period for a batch release: 18 mi nu tes Average stream flow during periods of release of effluent into a flowing stream: 3705 CFS (6)

2.2 MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY Waste gas releare at Hatch is confined to four paths. Each of these four gaths is continuously monitored for gaseous concentration and each has an integrating type collection device which concentrates particulates and iodine for each seven day period (Procedures are such that shorter collection times are used where applicable to Technical Specification requirements).

Each of these continuous samplers has a flow controller which maintains sample flow within about a 10 percent range over each seven day collection period. The offgas vent (elevated release) and the reactor building vents have flow measurement devices which continuously record the flow rate of the gas released (accuracy of these devices are within 10% of the actual fl.ows as measured during preoperational testing). The recombiner building vent fl ow on Unit One is conservatively assuaed to be constant at 500 CFM. In addition to the gaseous, particulate, and iodine release measurements tritium, gross alpha and gaseous isotopic neasurements of each vent stream are conducted on a monthly schedule.

(21)

After each calendar quarter (13 weeks) c summary of waste gas release from the four vents is compiled and as such is designed to meet the requirements for prepa"ation of the 6-month report as specified in Regulatory Guide 1.21. unit one and two releases were calculated together because the Tech. Specifications for tne two reactors are identical in this respect. The methods for compilation of the quarterly releases are as follows:

1. FISSION AND ACTIVATION GAS The total cur.e release is determined from the continuously reading gaseous monitors in addition to the vent ow recorders. Activity monitors and vent flow rate reaot.igs are read hourly and input into the computer. From these readings a daily release is calculated. The calibration factors fon the monitors are determined from the monthly isotopics when su"ficient activity allows or by injection of a known amount of off-gas into the sample chambers. The total curie release is calculated by the computer for each of the individual nuclides released. This number _ is multiplied by the average energy per disintignation (ET &

Ep) along with the coe fficien ts in the release limit formula in our Environmental Technical Specifications. All of the nuclides are summed and stored in their respective data files until the end of the quarter. Then the computer divides the sum of the nuclides by the seconds in the quarter to determine the percent of the tech. spec. limit released.

T

2. R ADI0 IODINE RELEASES Iodine releases are determined weekly for I-131, I-133, and I-135, for each vent. Where significant activity is not measured MDA releases are calcul'ted. Since calculated MDA's are below Technical Specification detectable concentrations then 0 (zero) release is used for the weeks with only MDA values. Weekly releases are summarized with the aid of the counting room calculator -

computer system and a quarterly total is prepared from the weekly summaries. The percent Technical Specification for I-131 on Table 2-1 is based on the quarterly Technical Specification limit.

3 PARTICULATE RELEASES Particulate releases are de te rmi ned weekly for each vent.

Where signifiennt activity is not measured MDA release is calculated. Since calculated MDA's are below Technical Specification detectable concentrations, then 0 (zero) release is used for weeks with only MDA valtes. Weekly rele,ses are sunmarized uith the aid of the counti.ng room calculator - computer.

(22)

After each calendar month the particulate fi 2 ters from each vent are combined, fused, and strontium separation is made.

Sinae sample flows and vent flows are almost constant, over each monthly period the filters from each vent can be dissolved togethea. Decay corrections are made back to the middle of the monthly collection period. Again the countin a room calculator - computer is used to aid in the calculation of the Sr-89, 90 release. Where significant strontium activity is not detected MDAs are calculated. In order to eliminate the need for a quarterly composite Sr-89 and Sr-90 activity is calculated for each monthly composite. The percent of Technical Specification was calculated using quarterly average equation.

4. GROSS ALPHA RELEASE The gross alpha release is competed 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 on a data sheet and the activity is summed at the end of the month.

S. TRITIUM R ELEASE Tritium staples 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 .' s measured upstream of the cold trap in order to alleviate the difficulties in dotermining water vapor collection e f f'ici enc ie s . The tritium samples are analyzed by an independent laboratory. From the uCi/ml tritium ccncentration, the grams water /ft3, and the vent flow ra ce s , the monthly tritium release is calculated for each vent, and the quarterly summary can be generated from the monthly calculation forms.

lintch has attempted to maintain all calculated MDAs as low as possible by counting samples longer than what would be nor 111y practical. For example at this time all weekly particualte and iodine counting times are 3000 see and strontium separations are counted for 100 minutes.

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.

"The total or maximum error associated with the effluent measurement will include the cumulative errors resulting from the total operation cf s a m p i. i n g and measurement.

Because it may be very difficult to assign error terms for each parameter affecting the final measurement, detailed ,

(23)

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. Fission and Activation Gas Total Release was calculated from process monitor readings. As 99.2% of the Xc-133 measur d was released from the main stack tne Kr-85 concentration was calculated *o be 1.26 E-ll uci/ml using 0.288 as the fission yield and basing the calculations on the measured release of Xe-133 With this number so far below the MPC limit of 3 X 10'7 the release was reported as 0.

Monitor Error in Calib ra ti on 50%

Vent Flow Rate 10%

Non-Steady Release Rate 20%

H5T

2. I-131 Release was calculated from each weekly sample:

Statistical error 60%

Counting Equipment Calibration 10%

Vent Flow Rates 10T Vent Sample Flow Rates 10%

Non-Steady Release Rates 10%

Losses From Charcoal Cartridge 10%

115T

3. Particulates with half-lives greater than 8 days release was dominated by the MDA calculations for I-131 and Ba-La-140 hence the errors in the strontium determinations and gross alpha had negligible affects on the estimated error in the total particulate release:

Statistical Error at MDA concentration 60%

Countng Equipment Calibration 10%

Vent Flow Rates 10%

Vent Sample Flow Rates 10%

Non-Steady Release Rates 10%

T565 4 Total Tritium Release was dominated by the reactor building vent PEItium release, hence, the larger statistical erroas of the off-gas vent and recombiner building vent tritium re le a s e.s do not affect the error in the total tritium release:

(24)

- Water Vapor in Sample Stream Determination 20%

Vent Flow Rates 10%

Counting Calibration and Statistics 10%

!!on-Steady Release 50%

1.2. KulMUM PERMISSIBI.E CO:!CE!!TRATIO::S

' The M?C values used in. determining allowable liquid radwaste release concentrations are taken frcm 10 CFR Part 20, Appendix B. Table II, Column 2. Release rate and dilution ratio for each batch are de-

, termined by a mixed nuclide MPC calculation performed before the re .

lease of the batch. To fat.ili ta te the mdasurements and calcula tions ,

the nuclides of Column 2 unich can be produced in a fission reactor

- have been grouped according to MPC value and type of radiation as shown in Figure 1-1. - .

e ,

(1)

The concentration of each of the 20 gamma emitting nuclides specifically noted in Figure 1-1 is measured individually because of interest in that nuclide or because of inadequate sensitivity for the nuclide from a gross activity measurement. For any of the 29 nuclides not detected in the gamma scan, the MDA lt att is computed from the ueasured data for that sample.

Only two pure beta emitters, Sr-84 and Sr-90, have MPC values less than 9 X 10 6 uCi/nl. Individual measurenents are made on proportional composite liquid radwaste samples to determine the Sr-89 and Sr oD concentration or MDA value to be applied to individual batch release calculations.

Although the MPC limit for tritium is greater then 9X 10 - 6 , a separate measurement is made for tritium since the gross beta technique does not provide an acceptable tritium measu"ement. A distilation and liquid scintillation counting technique is used to measure tritium concentration.

The maximum activity of gamma and beta emitting nuclides with MPC values greater than 9 X 10-6 uCi/ml, except for the 29 nuclides noted above, is determined by gross gamma and gross beta measurements. Measurement sensitivity linits of approxinately 2 cpm /ml allow a null measurement to show that the sum I (Ci/MPCI),

is less than 0.1 for gamma and beta nuclides not measured directly.

The sun of the ratios, I(Ci/MPCi), for alpha emitters can be shown to be less than 0.1 by a null measurement with a sensitivity limit of approximately 1 X 10 -2 cpa/ml. Gas flow counting is used to achieve the required sensitivity of measurement.

Thus, except for radionuclides produced in negligible quantities in a fission reaction (eg. I-125, I-129, etc.), the methods outlined above provide a means to assign a quantitatively measured or MDA value to all nuclides in Colunn 2. These measured and calculated concentration values for each batch are used to calculate the dilution ratio, release rate, and dilution rate prior to release of each batch. Both the concentration and release data are stored on a computer disc file. The disc file data is used to assure that quarterly and annual relea e limits are not exceeded. Bases used for the data of Table 1-1 are as follows:

A. Fission and activation products-The total release values (not including tritium, gases, alpha) are comprised of the sun of the individual "adionuclide activities .nd include the LLD concentration of all isotopes that were not measured but did not meat the mininum sensitivity li mi t as set forth in our Envirannental Tech Specc. This se is for each batch 4 - released to the river for the respective quarter. Percent of applicable limit is determined from a mixed n u e .* i d e MPC cal ci:1 a t t re . ha wc m ca mnecer m'4-- Nr ot* w' 4 (2)

summed over all batches is divided by the corresponding individual MPC value. The sum over all nuclides of the Ci/MPCi ra t i os times 100 is the percent of applicable limit for ef fluent releases during the quarter.

B. Tritium - The measured tritium concentration in a composite sample is used to calculate the total release and average diluted concentration during each period. Average diluted concentration divided by the MPC limit. 3 X lo - 3 aci/ml, is converted to percent to give the percent 01 applicable limit.

C. Dissolved and entrained gases - Concentrations of dissolved and entrained gases in liquid effluents are measured in each batch by Ce(Li) spectroscopy on a one liter sample from each liquid radwaste batch. Dissolved and entrained gases for which measured or MDA concentrations are determined include noble gases with half lives greater than 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months ; Xe-135, Xe-133m, Xe-133, and Kr-85. 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.

A conservative release limit, the maximum sensitivity limit of 10 - 5 uCi/ml of each dissolved and entrained radionuclide as specified in Regulatory Guide 1.21, has been applied in determining the percent of applicable limit.

D. Alpha measurements are taken monthly from the Liquid Radwaste composite. A study was instituted in July to determine if the catio method, as described in the E.T.S.

Table 2.1-1 footnote e could meet the LLD of 104 of the MPC value specified in 10 CFR part 20 Appendix B, Table II, column 2. That limit of 3 X 10 -9 uCi/ml was never exceeded during the study. Below is a summary of the study findings.

All other radionuclide concentration measurements are performed as indicated in the table given previously in this section and as detailed in the procedure HNP-7601. The dissolved gases cal cula ti on is performed in the Ge(Li) spectrometry system with computer datw reduction using the liquid Radwaste Library which includes gssses.

Several comments are indicative of the success of the HNP liquid radwaste program during this reporting period:

1. The total measured activity released in liquid effluent was 6.99 E-03 curie for the third quarter and 7.81 E-03 curie for the fourth quarter. These values were approximately 1/1430 and 1/1280 respectively, of the allowed 10 curies per quarter.

2. The radwaste release procedure strongly emphasizes reprocessing rather than discharge of liquid radwaste.

During this report period only 17.3% of the liquid radwaste reaching the sample tanks was discharged: 82.7% was recycled back inte the reactor water system.

3. A complete isotopic scan, gross beta, and gross gamma counts and computer analysis were performed prior to the release of each of the 180 discharge batches.

1.4 BATCH RELEASES Regulatory Guide 1.21 Tables 2A and 2B are found in this report as Table 1-1 and 1-2. Data is presented on a quarterly basis as per Regulatory Guide 1.21. If it is requested, a monthly ta b ula ti on will be submitted.

Other data pertinent to batch releases of radioactive effluent is as follows:

Nrmber of batch releases: 180 Total time period for releases: 22885 minutes Maximum time period for a batch release: 198 minutes Average time period for batch release: 127 minutes Minimum time period for a batch release: 18 minutes Average stream flow during periods of release of effluent into a flowing stream: 3583 CFS

Whenever the hydrogen monitor is inoperable during power operation, grab samples shall be taken and analyzed for hydrogen concentration each shift. Calibration check of the monitoring system shall be performed weekly.

2.2 MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY Waste gas release at Hatch I is confined to three paths. Each of these three paths is continuously monitored for gaseous concentration and each has an integrating type collection device which concentrates particulates and iodine for each seven day period (Procedure, are such that she tar collection times are used where applicabls to Technical Specification requirements).

Each of these continuous samplers has a flow controller which maintains sample flow within about a 10 percent range over each seven day collection period. The offgas vent (elevated release) and the reactor building vent have flow measurement devices which continuously record the flow rate of the gas released (accuracy of these devices are within 10% of the actual flows as measured during preoperational testing). The recombiner building vent flow is conservatively assumed to be constaat at 500 cfm. In addition to the gaseous, particulate, and iodine release measurement; tritium, gross alpha, and gaseous isotopic measurements of each vent stream are conducted on a monthly schedule.

After each ca .1 e n d a r quarter (13 weeks) a summary of waste gaa release from the three vents is compiled and as such is designed to meet the "cquirements for preparation of the 6- month recort as specirted in Regulatory Guide 1.21. The methods for compilation of the quarterly releases are as follows:

1. Fission and Actvation Gas The total curic release is determined from t'.e continuously reading gaseous monitors in addition to the vent flow recorders. Activity monitors and vent flow rate readings are read hourly and input into the computer. From these readings a daily release is calculated. The calibration factors for the monitors are determined from the monthly isotopics when sufficient activity allows or by in .i e c t io n of a known amount of off-gas into the sample chambers. The total curie release is calculated by the computer for each of the individual nuelides releaned. This number is multiplied by the average energy per Jisintegration (5 r &

Eg) and the coefficients in the release limit formula.

All the nuclides are summed and stored in their respective dat'a fil e s until the end of the quarter. Then the computer -

(16)

divides the sum of the nuclides by the seconds in the quarter to determine the percent of the tech, spec. limit releases.

2. RADIOIODINE RELEASES

_ Iodine releases are determined weekly for I-131, I-133, and 1-135, for each vent. Where significant activity is not measured MDA releases are calculated. Since calculated MDA's are below Technical Specification detectable concentrations then 0 (zero) release is used for the weeks with only MDA values. Weekly releases are summarized with the aid of the counting room calculator-computer system and a quarterly total is prepared from the weekly summarios.

The percent Technical Specification for I-131 on Table 2-1 is based on the quarterly Technical Specification limit.

3 PARTICULATE RELEASES Particulate release are determined weekly for each vent.

Ehere sig3ificant activity is not measured MDA rel_ ease is calculated. Since calculated MDA's are below Technical Specification detectable concentrations, then 0 (zero) release is used for weeks with only MDA values. Weekly releases are summarized with the aid of the counting room calculator - computer.

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 monthly collection period. Again the counting room calculator - computer is used to aid in the calculation of the Sr-89, 90 release. Where significant strontium activity is not detected MDAs are calculated. In order to eliminate the need for a quarterly composite Sr-89 and Sr-90

~

activity is calculated for each monthly composite. The percent of Technical Specification was calculated using the quarterly average equation.

4 GROSS ALPHA RELEASE The gross alpha release is computed each month by counting the particulate fil t e rs each week for gross alpha activity in a proportional counter. The four or five weeks numbers are then recorded on a data sheet and the activity is summed at the end of the month.

5. TRITIUM R ELEASE Tritium samples are. obtained monthly from each vent by

pa ssing the sample stream from a cold trap immersed in a .

(17)

liquid nitrogen or an acetone and ice mixture. The grams of water vapor / cubic foot gas is measured upstream of the cold trap inorder to alleviate the difficulties in determining water vapor collection efficiencies. The tritium samples are analyzed by an independent laboratory. Fcom the uCi/ml tritium concentration, the grams water /ft3, and the vent flow rates, the monthly tritium release is calculated for each vent, and the quarterly summary can be generated from the monthly calcualtlon forms.

Hatch I has attempted to maintain all calculated MDAs as low as possible by counting samples longer than what would be normally practical. For example at this time all weekly particualte and iodine counting times are 3000 see and strontium separations are counted for 100 minutes.

Regulatory Guide 1.21 requirrs 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.

"The total or maximum error associated with the effluent measurement will include the cumulative errors resulting from the total ope"ation of sampling and measurement. Because it may be very difficult to assign error terms for each pacameter affecting the final measurement, detailed stattstical evaluations of error are not suggested. The object've 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.

these actions to the Comission within 30 days from the end of the quarter during which the release occurred in accordance

. .. with section 5.7.2 of Tech Specs. ,

1.2. FAXIMUM PERMISSIBLE CONCENTRATIONS ' '.

The FPC values used in determining allowable liquid radwaste release '

concentrations are taken from 10 CFR Part 20, Appendix B, Table II,

, Column 2. Release rate and dilution ratio for each batch are de-termined by a mixed nuclide ??C calculation performed before the re- .

. lease of the batch. To facilitate the measurements and calcula tions, the nuclides of Column 2 which can be produced .in a fission reactor ,...

'.. ', have been grouped accor' ding to PPC value and type of radiation as shown in Figure 1-1. .

(1) . -

The concentration of each of the 29 gamma emitting nuclides lhI' specifically noted in figure 1-1 is measured individually because of interest in that nuclide or be ause of inadequate sensitivity for the nuclide from a gross activity measurement. For any of the 29 nuclides not de tec te d in the gamma scan, the MDA limit is computed from the measured data for that sample.

Only two pure beta emitters, Sr-89 and Sr-90, have MPC values less than 9X 10-6 uCi/ml. Individual measurements are made on proportional composite liquid radwaste samples to determine the Sr-89 and Sr-90 comcentration or MDA value to be applied to individual batch release calculations.

Although the MPC limit for tritium is greater than 9X 10 -6 , a separate measurement is made for tritium since the gross beta technique does not provide an acceptable tritium measurement. A distilation and liquid scintillation counting technique is used to measure tritium concentration.

The maximum activity of ganna and beta emitting nuclides with MPC values greater than 9 X 10-6 uCi/ml, except for the 29 nuclides noted above, is determined by gross gamma and gross beta measurements. Measurement sensitivity limits of approxinately 2 cpm /ml allow a null measurement to show that the sum E (Ci/MPCi), is less than 0.1 for gamma and beta nuclides not

.casured directly.

The sum of the ratios, E (Ci/MPC1), for alpha emitters can be shown to be less than 0.1 by a null measurement with a sensitivity limit of approxinately 1 X 10 - 2 cpm /mi. Gas flow counting is used to achieve the required sensitivity of measurement.

Thus, except for radionuclides produced in n e g li g i b l.e quantities in a fission reaction (eg. I-125, I-129, etc.), the methods outlined above provide a means to assign a quantitative measured or MDA value to all nuclides in Column 2. These measured and calculated concentration values for each batch are used to calculate the dilution ratio, release rate, and dilution rate prior to release of each batch. Both the concentration and release data are stored on a computer disc file. The disc file data is used to assure that quarterly and annual release limits are not exceeded. Bases used for the data of Table 1-1 are as follows:

A. Fission and activation products - The total release values (not including tritium, gases, alpha) are comprised of the

. , s . - . .

(2)

sum of the individual ra d i. so u c li d e activities and include the LLD concentrationof all isotopes that were not measured but did not meet the m '. n im u m sensitivity limit as set forth in our Environmental 'ech. Specs. This sum is for each batch released to ti a river for the respective quarter.

These values represent t ,. 2 activity known to be present in the liquid radwaste effluent. Percent of applicable limit is determined from a mixed nuclide MPC calcualtion. the average concentration for each nuclide summed over all batches is divided by the corresponding individual MPC 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.

B. Tritium - The measured tritium concentration in a composite sample is used to calculate the total release and average diluted concentration during each period. Average diluted concentration divided by the MPC limit, 3 X 10 - 3 uCi/ml, is converted to percent to give the percent of applicable limit.

C. Dissolved and entrained gases - Concentrations of dissolved and entrained gases in liquid effluents are measured in each batch by Ge(Li) spectroscopy on a one liter sample from each liquid radwaste batch. Dissolved and entrained cases for which measured or MDA concentrations are determined include noble gases with half lives greater than 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months ; Xe-135, Xc-133m, Xe-133, and Kr-35. Iodine radionuclides in any form are also determineu d aing the isotopic analysis for each batch, therefore a separate analysis for possible gascous forms is not performed because it would not provide additional information.

A conservative release limit, the maximum sensitivity limit of 10 - 5 uCi/ml of each dissolved and entrained radionuclide as specified in Regulatory Guide 1.21, has been applied in determining the percent of applicable limit.

D. Alpha measurements are taken conthly from the Liquid Radwaste composite. A study was instituted in July to determine if the ratio method, as described in the E.T.S.

Table 2.1-1 footnote could meet the LLD of 10% of the MPC value specified in 10 CFR part 20 Appendix B, Table II, Column 2. The limit of 3X 10-9 uci/ml was never exceeded during the study. Below is a summary of the study findings.

If a liquid radwaste tank cannnt he reprocessed, a sample for analysis is taken from the tank af ter the required recirculat ion time. The sample is used for gaao-ray spectroscopy, gross gar::ia and gross beta (nunting, and for preparatien of a composite sar ple.

The Ge(Li) detector systems consist of a 10% and two 15% efficiency, 2.0 s fuiM resolution detcctors in 4-inch thick lead shields. A one-liter rad.vaste liquid sarale is solidified in a furir.elli beaker in prepa-ration for a 2000-3000 second Ge(Li) count. A peak search of the resulting garca ray spectrum is perfort.:ed by the on-line co:rputer systen. Energy and net <ount data for all significant peaks are de-termined, and quantitative reduction or MDA calculations are perforrr.ed for the nuclic'es listed in Figure 1-1. The quantitative calcula-tions include correcticas for counting tire, decay time, sample volume, sample gec: retry, detector efficiency, baseline counts, and branching ratio. MDA calculations, 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 nuclide would be loccted if present.

~

The calculated radionuclide concentrations or l'CA values from the gamma scan and frca previcusly stored Sr-C9 and Sr-90 values are used to calculate the dilution ratio Y (Ci/MPCi) and allowable release parameters.

A sample printout is shcwn in figures 1-2 and 1-3.

The Liquid Radwaste Discharge Permit Printout is transferred item by itera to the first portion of the release permit (Figure 1-4) by a laboratory technician. Although the computer could printout the release permit and will inform the technician if a batch cannot be discharged as desired, a manual transfer of calculated results to the release permit by the technician was implemented as more likely to catch abnormal s conditions in the data.

The liquid rah:aste monitor setting is calculated by the ccmputer based on the gross gamma cctivity as measure.d in the sa:rple used for laboratory analysis. A coefficient has been determined which relates laboratory gross gann counts to the ranitor count rate. If the monitor courit rate exceeds the calculated settinq during discharge, then the liquid passing th. rough the monitor is not Fepresentative of the sangle which 'as analyzed in the lab. A monitor reading in excess of the cal-culatcd setpeint therefore results in an autcutic ter:rination of the liquid effluent discharge. Liquid effluent _discharce is also auto-matically terminated if the dilution flow rate falls belo- the flow rate used in the computer calculation.

1.' hen the release peruit is returned from Ra'dwaste Operations following discharge, the discharge data is combined uith the analysis results on the computer disc file. The disc file may be scanned to display trends in any recorded para:.;eter, or mTV be summed for reporting purposes as shown in Figure 1-5.

All other radionuclide concentration measurements are performed as indicated in the table given previously in this section and as detailed in the procedure HNP-7601. The dissolved gases calculation is performed in the Ge(Li) spectronotry system with conputer data reduction using the Liquid Radwaste Library which includes gases.

Several conments are indicative of the success of the HNP liquid radwaste program during this reporting period:

1. The total measured activity released in liquid effluent was 3.53 E-4 curie for the third quarter and 7.24 E-3 curie for the fourth quarter. These values were approximately 1/2832 and 1/1381 respectively of the allowed 10 curies per quarter.

2. The "adwaste release procedure strongly emphasized r e p r o c e s s i n:, rather than discharge of liquid radwaste.

During this report period only 32.42% of the liquid radwaste reaching the sample tanks was discharged: 67.58% was recycled back into both of the "eactor water systems.

3 A complete isotopic scan, gross beta, and gross gamma counts and computer analysis were performed prior to the release of each of the 386 discharge batches for both Units.

1.4 BATCH RELEASES Regulatory Guide 1.21 Tables 2A dnd 2B are found in this report as Table 1-1 and 1-2. Data is presented on a quarterly basis as per Regulatory Guide 1.21. If it is requested, a monthly tabulation will be submitted.

Other data pertinent to batch releases of radioactive e f fl u er. t from both units is as follows:

humber of batch releases: 386 Total time period for releases: 43990 minutes Maximum time period for a batch release: 227 minutes Average time period for batch release: 115 minutes Minimum time period for a batch release: 42 minutes Average stream flow during periods of release of effluent into a flowing stream: 3826 CFS

2.2 MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY Waste gas release at Hatch II is confined to two paths. Each of these two paths is continuously monitored for gaseous concentration and each has an integratirq tyne collection device which concentrates particulates and iodinc for each seven day period (Procedures are such that shorter collection times are used where applicable to Technical Specification requirements). Each of these continuous samplers has a flow controller which maintains sample fl ow within about a 10 percent range over each seven day collection period. The offgas vent (elevated release) and the reac tor building vent have fl ow measurement devices which continuously record the flow rate of the gas released (accuracy of these devices are within 10% of the actual flows as measured during preoperational testing). In addition to the gaseous, particulate, and iodine release measurements tritium, gross alpha, and gaseous isotopic measurements of both vent streams are conduc te d on a monthly schedule. After each calerdar quarter (13 weeks) a summary of waste cas release from the two vents is compiled and as.such is designed to ..

   ' meet the requirements for preparation of the 6-month report                        as specified,in Regulatory Guide 1.21.           Unit   one  and  two   releases (16)

were calculated separately because of the difference in the Tech. Specifications for the two reactors. However in the future we hope to combine both units into one report. The methods for compilation of the quarterly releases are as follows:

1. Fission and Activation Gas Total Release The total curie release is determined from the continuously reading gaseous monitors in addition to the vent flow recorders. Activity monitors and vent flow rate readings are read hourly and input into the computer. From these readings a daily release is calculated. The calibration factors for the monitors c-- datermined from the monthly isotopics when sufficient activity a: lows or by injection of a known amount of off-gas into the sample chambers. The total curic release is calculated by the computer for each of the individual nuclidcs released. This number is multiplied by the average energy per d i s i n t ig r a t i. on (Ey &

Ep) and the coefficients in the release limit formula in our Environmental Technical Specifications. All of the nuclides are summed and stored in their respective data files until the end of the quarter. Then the computer divides the sum of the nuclides by the seconds in the quarter to determine the percent of the tech. spec. limit released.

2. E ADI0 IODIN E RELEASES Iodine releases are determined weekly for I-131, I-133, and IZI35, for each vent. Where significant activity is not measured MDA releases are calculated. Since calculated MDA's are below Technical Specification detectable concentrations then 0 (zero) release is used for the weeks with only MDA values. Weekly releases are sunmarized with the aid of the counting room calculator -

computer system and a quarterly total is prepared from the weekly summaries. The percent Technical Specification for I-131 on Table 2-1 is based on the quarterly Technical Specification limit. 3 PARTICULATE RELEASES Particulate release are determined weekly for each vent. Ehere s IgnIficant activity is not measured MDA release is calculated. Since calculated MDA's are below Technical Specification detectable concentrations, then 0 (zero1 release is used for weeks with only t'D A values. Weekly releases are summarized with the aid of the counting room calculator - computer. After each c a l e r. d a r month the particulate filters from each

   -      vent are combined, fused, and strontium separation is made.

Since sampic fl ows and vent flows are almost constant over (17)

cach monthly period the filters from each vent can be dissolved together. Decay corrections are made back to the middle of the monthly collection occiod. Again the counting room calculator - computer is used to aid in the calculation of the Sr-89, 90 release. Where significant strontium activity is not detected MDAs are calculated. In order to eliminate the need for a quarterly composite Sr-89 and Sr-90 activity is calculated for each monthly composite. The percent of Technical Specification was calculated using the quarter 2.y average equation.

4. GROSS ALPHA R EL E A SE The gross alpha release is 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 on a data sheet and the activity is summed at the end of the month.

5. TRITIUM R ELEASE 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. From the uCi/ml tritium concentration, the grams water /ft3, and the vent flow rates, the monthly tritium release is calculated or each vent, and the quarterly summary can be generated from the monthly calculation forms.

Hatch 2 has attempted to maintain all calculated MDAs as low as possible by counting samples longer than what would be normally p ra c ti cal . For example at this time all weekly particualte and iodine counting times are 3000 see and strontium separations are sounted for 100 minutes. 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.

         "The total or maximum error associated with the effluent measurement will include the cumulative errors resulting from the      total    operation of sampling           anc      measurement.

Because it may be very difficult to assign ert'or terms for each parameter affecting the final measuf;aent, detailed atatistical evaluation of error are not suggested. The obj ec tive should be to obtain an ove ra ll estimate of the ~

       - error associated with measurements of radioactive materials released in liquid and gaseous effluents and solid waste."

(18)

Estimated errors arc based on errors in counting equipnent calibration, counting statistics, vent flow rates, vent sample flow ra t e s , non-steady release rates, chemical yield factors, and sample losses for such items as charcoal cartridges.

1. Fission and_ Activation Gan_ Total _ Release was calculated from process monitor readings.

2. I-131 Release was calculated from each weekly sample:

4. Total Tritium Release was dominated by the reactor building vent tritium release, hence, the larger statistical errors of the off-gas vent and recombiner building vent tritium releases do not affect the error in the total tritium release:
