I I SALEM GENERATING STATION RADIOACTIVE EFFLUENT RELEASE REPORT I JANUARY - JUNE 1995 INTRODUCTION I This report, SGS-RERR-38, 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 I for the period January 1, 1995 to June 30, 1995.

This Semiannual RERR is submitted for both Salem Units and I combines those sections which are common to each unit. Separate tables of releases and release totals are included whenever separate processing systems exist.

I 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 I criticality on December 11, 1976 and went into commercial operations on June 30, 1977.

Salem Unit 2 is a Westinghouse Pressurized Water Reactor which I has a licensed core power of 3411 MWt and an approximate net electrical output of 1115 MWe. Salem Unit 2 achieved initial criticality 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 I 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 I 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 I summary description of how measurements and determinations of the total activity discharged were developed.

a. MPC values were not used to determine the maximum I release rates for fission gases, iodines, or particulates.

b. MPC values as stated in 10CFR20, Appendix B, Table I II, Column 2 were used for liquids.

c. The MPC value used for dissolved or entrained I noble gases is 2E-4 microcuries per milliliter.

- 4 I

I I

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, I hence, this section does not apply.

4.0 MEASUREMENTS AND APPROXIMATION OF TOTAL RADIOACTIVITY I 4.1 Liquid Effluents Liquid effluents are monitored in accordance with Table I 4.11-1 of the Technical Specifications. During the period of record, all batch liquid wastes from the chemical drain tank and the laundry and hot shower I 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 I 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 I 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.

The detection requirements of Tables 4.11-1 of the Technical Specifications are achieved or exceeded.

I Radionuclides detected at concentrations below the Technical Specification detection limits (LLDs) are treated as being present. Radionuclides for which no activity was detected, while meeting the required LLDs, I are treated as absent.

4.2 Gaseous Effluents I 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 I point of all planned gaseous effluents and is continuously monitored by beta scintillator and high range GM tubes. The vent is also continuously sampled I for iodine and particulates with a charcoal cartridge and filter paper. The filter and charcoal are changed weekly, and ?~~lyzed on a multi-channel analyzer in I the laboratory.

~ 5 I

I

I I

Noble gas sampling is also performed on all gas decay tanks and containment purges prior to their release to the environment. The plant vent is sampled weekly for noble gases.

The detection requirements of Tables 4.11-1 and 4.11-2 of the Technical Specifications are achieved or I exceeded. Radionuclides detected at concentrations below the Technical Specification detection limits (LLDs) are treated as being present. Radionuclides for I which no activity was detected, while meeting the required LLDs, are treated as absent.

Continuous Mode gaseous releases are quantified by I routine (monthly or weekly) sampling and isotopic analyses of the plant vent. Specific activities for each isotope detected are multiplied by the total vent I flow volume for the entire sampling period in order to estimate the normal continuous release of radioactivity through the plant vent.

I Slightly elevated plant vent radiation monitor readings are treated as continuous releases. The monitors response is converted to a "specific activity" using I 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 I multiplied by the total volume of gas discharged for that batch.

Elevated plant vent ~adiation monitoring system I 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 I abnormal release is quantified by the use of the plant vent radiation monitors. The monitors response is converted to a "specific activity" using historical efficiency factors. The "specific activity" is I multiplied by the volume of effluent discharged while the channel was in an alarm state in order to estimate the total activity discharged.

I I 4.3 Estimated Total Error The estimated total error of reported liquid and solid I releases is within 25%

The estimated total error of the reported continuous gaseous releases is within 50% when concentrations exceed detectable I 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 I 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 I error est::_rwtes at the LLD are not defined.

5.0 BATCH RELEASES I Summaries of batch releases of gaseous and liquid effluents are provided in Tables 4A-l and 4B-l for Unit 1 and 4A-2 and 4B-2 for Unit 2.

I 6.0 UNPLANNED RELEASES I During this reporting period there were no unplanned releases.

7.0 ELEVATED R-16/R41C CHANNEL RESPONSES During this reporting period, there was one instance of an elevated :xinitor reading on Salem Unit 1 Rl6/R41C. On May I 19, 1995 ~he contents of the pressurizer relief tank was inadvertently released to the containment atmosphere. A containme~\t: purge was subsequently performed on 5/19/95 14:54 to 5/20/95 10:05 during which time the 1R16 plant vent I monitor alarm was actuated. There are no warning alarms or interlocks associated with the 1R16 radiation monitor. There are containment purge valve interlocks associated with the I 1R41C noble gas radiation monitor, however, no alarm was reported for the 1R41C radiation monitor. The radioactivity released from this purge resulted in a small fraction of the allowable limit and is included in the summary tables I presented in Table lA-1 and lB-1 of this report.

I a.o MODIFICATION TO PREVIOUS RADIOACTIVE EFFLUENT.'RELEASE REPORTS our last report (R~ 0 R-37) did not include the quarterly Sr-89, Sr*-90 and Fe-55 composite data for the fourth quarter I of 1994. 1~mended pages to RERR-37 are included at the end of this report.

PART D. SOLID WASTE I See Summary in Table 3.

PART E. RADIOLOGICAL IMPACT ON MAN I The calculated individual doses in this section are based on actual locations of nearby residents and farms. The I population dose impact is based on historical site specific data i.e., food production, milk production, feed for milk animals and seafood production.

I 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.

I Population doses were calculated using the meteorological dispersion coefficients for the six month reporting interval.

I Liquid Pathways I Doses to "maximum hypothetical individuals" in the population from liquid releases are primarily from the seafood ingestion pathway. Calculated doses to individuals are as shown below:

I Total body dose to the individual: 3.43E-Ol mrem Highest organ dose (GI-LLI): 1.48E+OO mrem I Dose to the 4.5 million individuals living within the 50 mile radius cf the plant site:

I Total population dose: 3.17E-02 person-rem Average population dose: 7.04E-06 mrem/person 8

Air Pathways I The calculated doses to "maximum hypothetical individuals" via the air pathway are shown below:

I Total body dose: 4.04E-03 mrem Skin dose: 9.85E-03 mrem I Highest organ dose due to radioiodines and particulates with half lives greater than 8 days:

I l.lOE-01 mrem to the Thyroid.

Dose to the 4.5 million individuals living within the 50 mile radius of the plant site:

I rota! population dose: 2.68E+OO person-rem I Average population dose: 5.96E-04 mrem/person I Direct Radiation Direct radiation may be estimated by thermoluminescent I dosimetric (TLD) measurements. One method for compa.ring TLD measurements is by comparison with preoperational data. It should be noted that the TLDs measure direct radiation from both the Salem and Hope I Creek Generating Stations at Artificial Island, as well as natural background radiation.

I TLD data for the six month reporting period is given below:

lLD Location Measu::-ement I 28-2 0.3 mile 4.3 mrad/month 58-1 0.9 mile 3.3 mrad/month I These values are interpreted to represent natural background. They are within the statistical variation associated with the pre-operational pr6gram I results, which are: 3.7 mrad/month for location 28-2, and 4.2 mrad/month for location 58-1.

I I:' 9 I

I

I I Total Dose 40CFR190 limits the total dose to members of the public I due to radioactivity and radiation from uranium fuel cycle sources to:

I <25 mrem total body or any organ

<75 mrem to the thyroid for a calendar year. For Artificial Island, the major I sour{~S of dose are from liquid and gaseous effluents from the Salem and Hope Creek plants.

I The following doses to members of the public have been calculated for the six month reporting period:

0.447 mrem total body I 1. 690 0.185 mrem mrem organ (GI-LLI) thyroid I Dose to Members of the Public Due to Activities inside the Site Boundary.

Assessment Gaseous effluents released from Salem resulted in a minimal dose to the maximum hypothetical individual.

The*air dose for the 6 month period was a small fraction of all applicable limits.

I Liquid effluent activity decreased slightly from previous reporting periods. Calculated doses are due principally to isotopes of iron, cobalt and cesium. The I dose from liquid effluents to the maximum hypothetical individual were well below all applicable limits.

The following two trend graphs show the total curies of I gaseous and liquid effluents released from Salem units 1 and 2 for the past 5 years. Calculated doses in the graphs are to the maximum hypothetical individual.

INOPERABLE MONITORS I During this period, the following effluent monitor was inoperable for more than 30 days:

I

Unit 1 Waste Gas Analyzer The waste gas analyzer could not be returned to service within the specified time period due to I extensive design changes. The design changes were necessary to prevent moisture accumulation in the waste gas analyzer. The analyzer was returned to I

service when the design changes were completed.

Unit 1 Steam Generator Blowdown Process Radiation Monitors (1R19 A,B,C,D)

The steam generator blowdown flow monitors could not be returned to service within the specified time due I to low S/G blowdown flow conditions. The low S/G blowdown flow was due to an extended shutdown of the reactor.

I

Unit 1 Containment Fan Coil Unit Process Radiation Monitor (1R130)

I The radiation monitor could not be returned to service within the specified time due to station planning workload and the unavailability of parts.

I

The monitor was inoperable for a total of 31 days.

Unit 2 Steam Generator Blowdown Process Radiation Monitors (2R19 A,B,C,D)

Incomplete tritium sample purification yielded artificially elevated tritium results. These results could not be I reverified by further analysis because the sample was inadvertently discarded.

I I 8. 0 MODIFICATION TO PREVIOUS RAD:OACTIVE EFFLUENT RELEASE REPORTS I our last report (RERR-36) did not include the quarterly Sr-89, Sr-90 and Fe-55 composite data for the second quarter of 1994. Amended pages to RERR-36 are included at the end of this report.

I PART B. GASEOUS EFFLUENTS I See summary Tables lA-1 thru lC for Salem Unit 1 Operations.

See Summary Tables lA-2 thru lC for Salem Unit 2 Operations.

PART c. LIQUID EFFLUENTS I See summary Tables 2A-1 thru 2B for Salem Unit 1 Operations.

See Summary Tables 2A-2 thru 2B for Salem Unit 2 Operations.

I PART D. SOLID WASTE See Summary in Table 3.

I PART E. RADIOLOGICAL IMPACT ON MAN I 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 I animals and seafood production.

The doses were calculated using methods described in I 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 I described in the Offsite Dose Calculation Manual.

Population doses were calculated using the meteorological dispersion coefficients for the six month reporting I interval.

Liquid Pathways I Doses to "maximum hypothetical individuals" in the population from liquid releases are primarily from the seafood ingestion pathway. Calculated doses to I individuals are as shown below:

Total body dose to the individual: 5.85E-Ol *:.::n I Highest organ dose (GI-LLI): 8.54E-Ol mrem Dose to the 4.5 million individuals living within the 50 mile radius of the plant site:

I I Total population dose: 7.44E-02 person-rem Average population dose: 1.65E-05 mrem/person I

Air Pathways I The calculated doses to "maximum hypothetical individuals" via the air pathway are shown below:

I Total body dose: 1.07E-02 mrem Skin dose: 2.60E-02 mrem I Highest organ dose due to radioiodines and particulates with half lives greater than 8 days:

I 1.71E-02 mrem to the Thyroid.

Dose to the 4.5 million individuals living within the I 50 mile radius of the plant site:

Total population dose: 1.84E-Ol person-rem I Average population dose: 4.09E-05 mrem/person I Direct Radiation-I 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 I measure direct radiation from both the Salem and Hope Creek Generating Stations at Artificial Island, as well as natural background radiation.

I TLD data for the six month reporting period is given below:

I TLD Location Measurement 2S-2 0.3 mile 3.9 mrad/month I 5S-1 0.9 mile 3.1 mrad/month These va11-~- are interpreted to represent natural background. They are within the statistical I 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 .
