- INTRODUCTION SALEM GENERATING STATION RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - JUNE 1992 This report, SGS-RERR-32, summarizes information pertaining to the releases of radioactive materials in liquid, gaseous and solid form from the Salem Generating Station {SGS) Units 1 and 2 for the period January 1, 1992 to June 30,* 1992.
This Semiannual RERR is submitted for both Salem Units and combines those sections which are common to each unit.
Separate tables of releases and release totals are included whenever separate processing systems exist.
Salem Unit 1 is a Westinghouse Pressurized Water Reactor which has a licensed core power of 3411 MWt and an approximate net electrical output of 1115 MWe.
Salem Unit 1 achieved initial criticality on December 11, 1976. and went into commercial operations on June 30, 1977.
Salem Unit 2 is a Westinghouse Pressurized Water Reactor which has a licensed core power of 3411 MWt and an approximate net electrical output of 1115 MWe.
Salem Unit 2 achieved initial cri~icality on August 2, 1980 and went into commercial operations on October 13, 1981.
The report is prepared in the format of Regulatory Guide 1.21, Appendix B, as required by Specification 6.9.1.11 of the Salem Technical Specifications. Preceding the tables summarizing the gaseous and liquid discharges and solid waste shipments are our responses to parts A-F of the "Supplemental Information" section of Regulatory Guide 1.21, Appendix B.
As required by Regulatory Guide 1.21, our Technical Specification limits are described in detail within this report along with a summary description of how measurements and determinations of the total activity discharged were developed.

- a.
- b.
- c.
MPC values were not used to determine the maximum release rates for fission gases, iodines, or particulates.
MPC values as stated in 10CFR20, Appendix B, Table II, Column 2 were used for liquids.
The MPC value used for dissolved or entrained noble gases is 2E-4 microcuries per milliliter.
4
3.0 AVERAGE ENERGY Regulatory Guide 1.21 requires that the licensee provide the average energy of the radionuclide mixture in releases of fission and activation gases, if applicable.
Release limits for SGS are not based upon average energy, hence, this section does not apply.
4.0 MEASUREMENTS AND APPROXIMATION OF TOTAL RADIOACTIVITY
- 4.1 Liquid Effluents Liquid effluents are monitored in accordance with Table 4.11-1 of the Technical Specifications.
During the period of record, all wastes from the chemical drain tank and the laundry and hot shower tanks were routed to the hold-up tanks for monitoring prior to release.
Technical Specifications require these tanks to be uniformly mixed for sampling and analysis before being released.
Batch releases are defined as releases from the waste monitor hold-up tank and the chemical and volume control tanks.
Continuous liquid releases are defined as condensate releases from intermittent blowdown of the steam generators.
Specific activities from analyses were multiplied by the volume of effluent discharged to the environment in order to estimate the total liquid activity discharged.
4.2 Gaseous Effluents Gaseous effluent streams are monitored and sampled in accordance with Table 4.11-2 of the Technical Specifications.
The plant vent is the final release point of all planned gaseous effluents and is continuously monitored by beta scintillators and high range GM tubes.
The vent is also continuously sampled for iodine and particulates with a charcoal cartridge and filter paper connected in series to a low volume air sampler.
The filter and charcoal are changed weekly, and analyzed on a multi-channel analyzer in the laboratory.
Sampling is also performed on all gas decay tanks and containment purges prior to their release to the environment.
The plant vent is sampled for noble gases monthly.
The detection requirements of Tables 4.11-1 and 4.11-2 of the Technical Specifications are achieved or exceeded.
Radionuclides measured at concentrations below the Technical Specification detection limits (LLDs) are treated as being present. Radionuclides for 5
which no activity was detected, while meeting the required LLDs, are treated as absent.
Continuous Mode gaseous releases are quantified by routine (monthly or weekly) sampling and isotopic analyses of the plant vent.
Specific activities for each isotope detected are multiplied by the total vent flow volume for the entire sampling period in order to estimate the normal continuous release of radioactivity through the plant vent.
Slightly elevated plant vent radiation monitor readings are treated as continuous releases.
The monitors response is converted to a "specific activity" using historical efficiency factors.
The "specific activity" is multiplied by a default volume of effluent discharge to estimate the total activity discharged.
Batch Mode gaseous releases are quantified by sampling each gas decay tank or containment purge prior to discharge..specific activities for each isotope are multiplied by the total volume of gas discharged.
Elevated plant vent radiation monitoring system readings while the channel is in an alarm state are treated as batch mode releases. If specific activity data from grab samples taken is not available, then the abnormal release is quantified by the use of the plant vent radiation monitors.
The monitor's response is converted to a "specific activity" using historical efficiency factors.
The i*specific activity" is multiplied by the volume of effluent discharged while the channel was in an alarm state in order to estimate the total activity discharged.
4.3 Estimated Total Error The estimated total error of reported liquid and solid releases is within 25%
The estimated total error of the reported continuous gaseous releases is within 50% when concentrations exceed detectable levels.
This error is due primarily to variability of waste stream flow rates and changes in isotopic distributions of waste streams between sampling periods.
The estimated total error of the reported batch gaseous releases is within 10%.
Error estimates for releases where sample activity is below the detectable concentration levels are not included since error estimates at the LLD are not defined.

PART E.
RADIOLOGICAL IMPACT ON MAN The calculated individual doses in this section are based on actual locations of nearby residents and farms.
The population dose impact is based on historical site specific data i.e., food production, milk production, feed for milk animals and seafood production.
The doses were calculated using methods described in Regulatory Guide 1.109 and represent calculations for the six month reporting interval.
Individual doses from batch and continuous releases were calculated using the annual average historic meteorological dispersion coefficients as described in the Offsite Dose Calculation Manual.
Population doses were calculated using the meteorological dispersion coefficients for the six month reporting interval.
Liquid Pathways Doses to individuals in the population from liquid releases are primarily from the seafood ingestion pathway. Calculated doses to individuals are as shown below:
Total body dose to an individual:
4.06E-Ol mrem Highest organ dose:
2.82E+OO mrem to the GI-LLI.
Dose to the 6 million individuals living within the 50 mile radius of the plant site:
Total population dose:
8.SOE-02 person-rem Average population dose:
l.47E-05 mrem/person 8
L Air Pathways The calculated doses to individuals via the air pathway are shown below:
Total body dose: 1.62E-02 mrem Skin dose:
l.SOE-02 mrem Highest organ dose due to radioiodines and particulates with half lives greater than 8 days:
9.llE-03 mrem to the Thyroid.
Dose to the 6 million individuals living within the 50 mile radius of the plant site:
Total population dose:
2.44E-Ol person-rem Average population dose:
4.09E-05 mrem/person Direct Radiation Direct radiation may be estimated by thermoluminescent dosimetric (TLD) measurements.
One method for comparing TLD measurements is by comparison with preoperational data.
It should be noted that the TLDs measure direct radiation from both the Salem and Hope Creek Generating Stations at Artificial Island, as well as natural background radiation.
TLD data for the six month reporting period is given below:
TLD 2S-2 5S-1 Location 0.3 mile 0.9 mile Measurement 5.7 mrad/month 4.9 mrad/month These values are intepreted to represent natural background, since they are within the statistical variation associated with the pre-operational program results, which are: 3.7 mrad/month for location 2s-2, and 4.2 mrad/month for location 5S-1.
9
Total Dose 40CFR190 limits the total dose to members of the public due to radioactivity and radiation from uranium fuel cycle sources to:
<25 mrem total body or any organ
<75 mrem to the thyroid for a calendar year. For Artificial Island, the major sources of dose are from liquid and gaseous effluents from the Salem and.Hope Creek plants.
The following doses to members of the public have been calculated for the six month reporting period:
0.778 2.930 0.179 mrem total body mrem organ (GI-LLI) mrem thyroid Dose to Members of the Public Due to Activities inside the Site Boundary.
In accordance with the requirements of Technical Specification 6.9.1.7, the dose to members of the public inside the site boundary has been calculated based on the following assumptions:
- Such persons are participating or spectators in local softball league
- 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> per week on site
- Dose due to airborne pathway(inhalation and immersion)
- persons are located about 3/4 mile east of plant discharge points {baseball fields)
- occupancy coincides with batch gaseous discharges For the six month reporting period, the calculated doses are:
6.61E-05 6.96E-05 6.61E-05 mrem Total Body mrem Organ mrem Thyroid 10
Assessment Gaseous effluents continue to be low and are predominately xenon-133. Calculated doses are low, due to the dose factor of xenon-133.
Liquid effluents increased slightly from previous reporting periods. Calculated doses are due principally to isotopes of iron, cobalt and cesium.
The following two trend graphs show gaseous and liquid effluents and calculated doses from combined Salem 1 and 2 for the previous five years.

METEOROLOGICAL DATA Cumulative joint wind frequency distributions by atmospheric stability class at the 300 foot elevation are provided for the first and second quarters of 1992 in Tables 5 and 6.
OFFSITE DOSE CALCULATION MANUAL (ODCM) CHANGES During this period, there were was a revision to the SGS ODCM. Revision 7 was approved on 1/16/92, a summary of the revision along with the pages that were changed is included in an addendum to this report.
INOPERABLE MONITORS During this period, the following effluent monitors were inoperable for more than 30 days
- Unit 2 Plant Vent Noble Gas Monitor (2R41C)
- Unit 2 Chemical Waste Basin Process Monitor (2R37)
- Unit 2 Steam Generator Blowdown Process Monitors
( 2 Rl 9 A, B, C, D)
These monitors could not be returned to operating status within the 30 day time period due to a forced shutdown on Unit 2 and Design Change work being performed on the monitors.
Unit 2 Plant Vent Noble Gas Monitor (2R41C) - Monitor was inoperable for more than 30 days due to design change work being performed on the monitor (DCP 2EC-3086). Work included a primary calibration of the detector and the replacement of electronic components.
Unit 2 Chemical Waste Basin Process Monitor (2R37) -

RADIOLOGICAL IMPACT OH MAH The calculated individual doses in this section are based on actual locations of nearby residents and farms.
The population dose impact is based on historical site specific data i.e., food production, milk production, feed for milk animals and seafood production.
The doses were calculated using methods described in Regulatory Guide 1.109 and represent calculations for the six month reporting interval.
Individual doses from batch and continuous releases were calculated using the annual average historic meteorological dispersion coefficients as described in the Offsite Dose Calculation Manual
- Population doses were calculated using the meteorological dispersion coefficients for the six month reporting interval.
Liauid Pathways Doses to individuals in the population from liquid releases are primarily from the seafood ingestion pathway. Calculated doses to individuals are as shown below:
Total body dose to an individual:
3.83E-Ol mrem Highest organ dose:
1.79E+OO mrem to the GI-LLI.
Dose to the 6 million individuals living within the so mile radius of the plant site:
Total population dose:
7.lOE-02 person-rem Average population dose:
1.19E-05 mrem/person 8

REVISION 7 TO SALEM ODCM
REVISION 7 OF THE SALEM OFFSITE DOSE CALCULATION MANUAL Attached is a breakdown of the revisions made to the Salem Generating Stations Offsite Dose Calculation Manual (ODCM). The revisions were made to satisfy part B closure of some DCP's and to update information contained in the ODCM.
Chanqe f 1 page 5 bottom Change From:
Use of the effective MPC value as derived in Appendix A may be non-conservative for the R-19 Steam Generator Slowdown monitors and R37 Chemical Waste Basin monitors where I-131 transfer during primary to secondary leakage may potentially be more controlling blowdown monitors, lR13** Service Water monitor and R37 Chemical Waste Basin monitor~
Change to:
Based upon the potential for I-131 to be present in the secondary and service water systems, the use of the default effective MPC value as derived in Appendix A may be non-conservative for the 1Rl9 and 2Rl9 SGBD monitors, the R-37 Chemical Waste Basin Monitor and the lR-13 Service Water Monitors.

Mtq. # 7 ""'- 007
Salem ODCM Rev. 7 The radioactivity monitor setpoint equation (1.2) remains valid during outages when the circulating water dilution is potentially at its lowest value.
Reduction of the waste stream flow (RR) may be necessary during these periods to meet the discharge criteria.
However, in order to maximize the available plant discharge dilution and thereby minimize the potential offsite doses, releases from either Unit-1 or Unit-2 may be routed to either the Unit-l or Unit-2 Circulating Water System discharge.
This routing is possible via interconnections between the Service Water Systems (see Figures land 2).
Procedural restrictions prevent simultaneous releases from either a single unit or both units into a single Circulating Water System discharge.
1.2.2-Conservative Default Valu***
Conservative alarm setpoints may be determined through the use of default parameters.
Tables 1-1 and l-2 summarize all current default values in use for Salem Unit-l and Unit-2, respectively.
They are based upon the following:
a) substitution of the effective MPC value with a default value of 4.71E-06 uCi/ml (Unit 1) and 3.38E-.06 uci/ml (Unit 2). (refer to Appendix A for justification);
b) for additional conservatism*, substitution of the I-131 MPC value of 3E-07 uci/ml for the Rl9 Steam Generator Slowdown Monitors, the R-37 Chemical Waste Basin monitor and the R-13 Service Water Monitors.
- Based upon the potential for I-131 to b* present in the secondary and service water systems, the use of the default effective MPC value as derived in Appendix A may be non-conservative for the 1, 2 R-19 SGBD monitors, the R-37 Chemical waste Basin Monitor and the R-13 Service Water Monitors.
5
c) d)
Salem ODCK Rev. 7 substitutions of the operational circulatinq water flow with the lowest flow, in qal/min: and, substitutions of the effluent release rate with the highest allowed rate, in gal/min.
With pre-established alarm setpoints, it is possible to control the radwaste release rate (RR) to ensure the inequality of equation (1.2) is maintained under changing values for MPCe and*
for differing Circulating Water System dilutions
- The Unit 2 seriice Water system utilizes the Unit l Circulating Water syat.. tor dilution prior to release to th* river. It is possible to have the Unit l Circulating Water system out of service when Unit l is in an outage.
So, for conservatism no dilution is used for determining a 2Rl3 default alarm setpoint.
Because no dilution is considered and the 2Rl3 monitor sensitivity is high, the ~* of 3.38E-06 uCi/ml is used in calculating the alarm setpoint (otherwise using JE-07 uCi/ml would result in an alarm setpoint of l cpm)

~ an effective MPC value for a mixture of radionuclide (uCi/ml) concentration of radionuclide i in the mixture the 10 CFR 20, Appendix B, Table II, Column 2 MPC value for radionuclide i (uCi/ml)
The equation for determininq the liquid effluent setpoints ( Section 1.2.l, equation 1.2 ) is based on a multiplication of the effective MPC times the monitor sensitivity. However, the radiation monitors on the effluent lines will not detect non-qamma emittinq radionuclides, such as H-3, Fe-55, and Sr-90. The derivation *of the effective MPC ( Section 1.2.l, equation 1.3*) is valid for any distribution but must be modified to account for the fact that the effluent monitor will not detect the non-gammas. Th* above modified equation for the effective MPC provides for a default satpoint determination that accounts *for the non-gamma emitting radionuclide*
