[ ')
The MPC values used in determining allowable
^
\\ /-
11guld radwaste release rates and concentrations for principal ganna emitters, I-131, tritium, St-89, Sr-90 and Fe-55 are taken from 10CFR Part 20, Appendix B, Table II, Column 2.
For dicsolved or entrained noble cases in liquid radwaste, the MPC is taken from Technical Specification 3.15.1.1 (Unit 1) ard 3.11.1.1 (Unit
- 2) as 2.0E-04 uC1/ml.
For gross alpha in 11guld radwaste, the MPC 2s taken from 10CFR Part 20, Appendix B, Note 2.b as 3.0E-03 uC1/ml.
Further, for all the above radionuclides or categories of radioactivity, the overall MPC fraction is determined in accordance with 10 CPR Part 20, Appendix B, Note 1.
The method whereby the MPC f racticn is used to determine release rates and 11guld radwaste effluent radiation monitor setpoints is described in Section 1.3 of this report.
(
1.3 MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY Prior to releace of any tank containing liquid radwaste, and following the regul:ed recirculation, samples are collected and analyzed in accordance with Technical Specification Tables 4.15.1-1 (Unit 1) and 4.11.1-1 (Unit 2).
A sample from each tank planned for release is analyzed for principal gamma emitters, I-131, and dissolved and entrained noble casca by gamma srectrometry.
Monthly and quarterly composites are prepared for analysis by extracting aliquots from each sample taken from tanks which are released.
Ligurd radwaste samric analyses are performed as follows:

Gamm isotopic measurements are performed in-house in the radiochemistry lab usino aermanium spectrometry.
Three germanium detectors are available:
a 20%
efficient and two 15% efficient intrinsic aermnium detectors, with 2.0 fvHM resolution and housed in 4 2nch-thick lead shields. A one-liter 11guld radwaste sample is poured into a Marinella beaker in preparation for a 3000 second count. A peak search of the resulting camm ray spectrum is performed by the p
computer system. Energy and net count data for all (v) significant peaks are determined, and quantitacave reduction or LLD calculations are performed for the l
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, Fe-59, co-58, co-60, 2n-65, Mo-99, t
Cs-134, Cs-137, Ce-141 and Ce-144 The quantitative calculations include corrections for counting time, decay time, sample volume, sample geometry, detector l
efficiency, baseline counts, and branching ratto. LLD l.
calculations, includina 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 radionuellde would be located if present.
The radionuclide concentrations determined by camma spectroscoolc analysis of a sample taken from a tank planned for release and the most current sample analysis results available for tritium, cross alpha, Sr-89, Sr-90,. and Fe-55 are used alono with the corresponding MPC values to determine an MPC fraction for the tank planned for release. This MPC fraction l

(/
to assure that the limits of Technical Specifications 3.15.1.1 (Unit 1) or'3.11.1.1 (Unit 2) are not exceeded.

Radlonuclidt concentrations, safety factors, I
dilution stream flow rate, and 11guld effluent 1
<;adiation monitor calibration factor are entered into the computer and a prerelease printout is 1
generated.
If the release 18 not termissible appropriate Warnings will be included on the prerelease prantout.
If the release is permissible it is approved by the Chemistry Foreman on duty. The pertinent infornation is transferred manually from the prerelease printout I
to a one-page release termit which as forwarded to Radwaste Operations.
When the release is completed the release permit is returned from Radwaste Operations with actual release data included. These data are input to the computer and a post release printout is generated. The post release trintout contains actual release rates, actual release concentrations and quantitles, actual dilution flow, and calculated doses to an individual,

1.4 LIQUID EFFLUEtc RELEASE DATA Reculatory Guide 1.21 Tables 2A and 28 are found in this report. as Table 1-2a for Unit 1, Table 1-2b for Unit 2 and Tab.?e 1-2c for the siter and Table 1-3a for Unit 1, 1-3b for Unit 2, and Table 1-3c for the site.
The values for the four categories of Tables 1-2a and 1-2b, and 1-2c are calculated and the Tables completed as follows:
1.
Fission and activation products - The total release values (not including tritium, cases, and alpha) are comprised of the sum of the measured individual radionue12de activities. This sum 1s -for each batch released to the river for the respective O

Lti quarter.
Percent of applicable limit is determined from a mixed nuclide MPC fraction
/~T-calculation. The average concentration for i)
each nuellde over all released batches is divided by the corresponding individual MPC value. The sum over all nuelldes of the C/MPC ratios times 100 is the percent of apo11 cable 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. Averace diluted concentration divided by the MPC limit, 3.00-03 uC1/ml, is converted to percent to otve the percent of applicable limit.
3.
Dissolved and entrained cases -
Concentrations of dissolved and entrained gases in liquid effluents are measured by germanium spectroscopy on a one liter samole from each 11guld radwaste batch. The average concentration of dissolved or entrained noble gases for all released batches is div2ded by the MPC value stated In Technical Specifications 3.15.1.1 and
.f 3.11.1.1 ( 2.0E-04 uC1/ml) to determine the i
\\
MPC fraction. The result x100 la the percent of applicable limit for noble cases in liquid effluent releases during the quarter.
Radioisotopes of lodine in any form are also determined durinq 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 l
composite samples are used to calculate the total release of alpha radioactivity.

~ Waste gas release-at Plant Hatch is confined to 4
- four paths: main stack (also called the offgas
(
vent)~, Unit 1; reactor building vent: Unit 2 reactor building vent, and the recombiner-i building vent. -Each of these four paths is continuously monitored for gaseous radioactivity.
Each is equipped w; W an integrating-type samle' collection device for collecting particulates and lodines. Samole collection-is in'accordance with Technical Specification Tables 4.15.2-1 (Unit 1) and
.[
4.11.2-1.(Unit 2)..Unless required more g
frequently under-certain circumstances specified in Table Notations to the above mentioned tables, samples are collected as follows:,
m 1.
Noble gas samles are collected by Arab 4'
sampling monthly.
2.
Tritium.samles are collected by grab sampling monthly.
3.
Radioiodine samles are collected by pulling the sample stream through a charcoal v ;tridge over a 7-day petlod.

The noble gas grab sample analysis results are used along with maximum expected release flow rates from each of the four vents to calculate f(Y monitor setpoints for the gaseous ef fluent
(,,/
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.a (Unit 2) are not exceeded. Calculation of monitor setpoints is described in the Plant Hatch ODCM.
With each release period released radioactivity, dose rates, and cumulative 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 1): 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 quantitles of radioactivity, dose rates and cumulative doses are as o
follows:
Lt 1.
FISSION ANu ACTIVATION GAS The radionuclide-specific released radioactivity is determined from sample analyses results collected as described above and averaqe release flow rates over the period represented by the collected sample.
Instantaneous dose rates due to noble gases and due to radiolodines, tritium, and particulates are calculated (with computer assistance).
Calculated dose rates are compared to the dose rate limits specified in 3.15.2.1.a (Unit 1) and 3.11.2.1.a (Unit 2) for noble gasest and 3.15.2.1.b (Unit 1) and 3.11.2.1.b (Unit 2) for radiolodine, tritium, and particulates. Dose rate calculation methodology is presented in the Plant Hatch 00CM.

After each calendar' quarter the particulate y

flows and vent-flows =are almost-constant over 9
each quarterly period the filters from each vent can be dissolved together. ' Decay corrections-are made back_ to the ' middle of the quarterly B

The purpose of this section is to acknowledae the f ailure to meet the lower limit of detection (LLD) requirement for Sr-89 when analy:Ino two 11guld composite samples representina the second quarter 1990, and to discuss the potential impact on 11guld effluent values reported in the HNP Semlannual Radioloq1 cal Ef fluent Pelease Peport for the first six months of 1990.
The lower limit of detection for St-89 in 11guld ef fluent samples spec 1 fled in Technical Specification Table 4.15.1-1 (Unit 1) and Table 4.11.1-1 (Unit 2) is SE-8 uC1/ml.
In both instances in which the required lower linut of detection was not achieved, the primsry cause was inadequate sanole size.
For the Unit 1 11guld effluent samole compos 1ted durano the second quarter 1990, results of analysis for St-89 were reportel as less than 7E-8 uC1/ml. Positive composite sample results are norna11y reported to two significant figures. Therefore, St-89 could potentially have teen present in Unit 1 liquid effluent at a concentration of 6.9E-8 uC1/ml.
During the second quarter 1990, 4.78E6 11ttes of 11guld effluent were released from Unit 1, Therefore, 3.3E-4 curies of Sr-89 potentially nay have been released in Unit 1 11guld effluent during the second quarter 1990.
This amount of radioactivity would not have affected the " fission and activation products
- total which was reported as 1.35E-1 curies in Table 1-2a of the Semiannual Radiological Effluent Pelease Ih Repsct for the first six months of 1990. While the "t of
\\- '
applicable 11nat" would be sllchtly increased, it would remain less than one-third of one percent.
Doses to an individual, reoorted in Table 1-4a of the aforemen*.ioned report, would not be increased due to this amount of Sr-89 in Unit 1 liquid ef fluent.
For the Unit 2 liquid effluent sample camposited during the second quarter 1990, results of analysis for Sr-89 were reported as less than 6E-8 uC1/ml. Therefore, Sr-89 could have been present in Unit 2 11guld effluent at a concentration of 5.9E-8 uC1/ml. During the second quarter 1990, 2.43E6 liters of liquid effluent were released from Unit 2, potentially resulting in a release of 1.43E-4 curies of Sr-89. This amount of radioactivity would have increased the
" fission and activation products" total, presented in Table 1-2b of the Senuannual Radioloq1 cal Effluent Pelease Report for the first six months of 1990, from 1.13E-2 curies to 1.14E-2 curies, which would be an increase of less than one percent. Although the "% of applicable limit" would be increased s11ohtly, it would remain approxinately one-fourth of one percent. Doses to an individual, reported in Table 1-4b of the report mentioned above, would not be increased due to this-amount of Sr-89 in Unit 2 liquid ef fluent.
In summary, althouah Sr-89 may hav. been present in liquid effluents released from Plant Hatc; during the second quarter 1990, the ef fect on reported quantitles of radioactivity released would
(~l have been minimal.
Potential doses to an Individual resulting from
\\m /
Sr-89 in liquid effluents would have been too sna11 to affect reoorted doses. l J
