SALEM GENERATING STATION RADIOACTIVE EFFLUENT RELEASE REPORT JULY - DECEMBER 1998

INTRODUCTION This report, SGS-RERR-45, 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 July 1, 1998 to December 31, 1998.

This semiannual Radioactive Effluent Release Report (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 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, as required by Specification 6.9.1.8 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.

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 .

1

To facilitate determination of compliance with 40CFR190 requirements, the following information on electrical output is provided.

Unit 1 generated 4,139,144 megawatt-hours of electrical energy (net) during the reporting period.

Unit 2 generated 4,045,853 megawatt-hours of electrical energy (net) during the reporting period.

The Sr-89, Sr-90 and Fe-55 analyses for the first half of 1998 (refer to RERR-44) have been completed. Composite analyses for tritium released through the chemical waste basin were.also completed. *Amended pages to RERR-44 are included in this report .

PART A. PRELIMINARY SUPPLEMENTAL INFORMATION 1.0 REGULATORY LIMITS

1.1 Fission and Activation Gas Re1ease Limits The dose rate due to radioactive materials released in gaseous effluents from the site to areas at and beyond the site b6undary, shall be limited to the following:

For noble gases: Less than or equal to 500 mrem/yr to the total body and less than or equal to 3000 mrem/yr to the skin.

In addition, the air dose due to noble gases released in gaseous effluents, from each reactor unit, from the site to areas at and beyond the site boundary, shall be limited to the following:

For Iodine-131, for tritium, and for all :

radionuclides in particulate form with half lives greater than 8 days: Less than or equal to 1500 mrem/yr to any organ.

In addition, the dose to a member of the public from Iodine-131, from tritium, and from all radionuclides in particulate form with half-lives greater than 8 days in gaseous effluents released, from each reactor unit, from the site to areas at and beyond the site boundary, shall be limited to the following:

During any calendar quarter: Less than or equal to 7.5 mrem to any organ~ and During any calendar year: Less than or equal to 15 mrem to any organ .

3

1.3 Liquid Effluents Release Limits

The concentration of radioactive material released in liquid effluents to unrestricted areas shall be limited to the concentrations specified in 10 CFR, Part 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 microcuries per milliliter.

In addition, the dose or do"se commitment to a member of the public from radioactive materials in liquid effluents released to unrestricted areas shall be limited to:

During any calendar quarter to less than or equal to 1.5 mrem to the total body and to less than or equal to 5 mrem to any organ, and During any calendar year to less than or equal to 3 mrem to the total body and to less than or equal to 10 mrem to any organ.

1.4 Total Dose Limit The annual (calendar year) dose or dose commitment to

any member of the public, due to releases of radioactivity and radiation, from uranium fuel cycle sources shall be limited to less than or equal to 25 mrem to the total body or any organ (except the thyroid, which shall be limited to less than or equal to 75 mrem).

2.0 MAXIMUM PERMISSIBLE CONCENTRATIONS (MPC)

Regulatory Guide 1.21 requires that the licensee provide the MPCs used in determining allowable release rates for radioactive releases.

a. MPC values were not used to determine the maximum release rates for fission gases, iodin~s, or particulates from gaseous releases.

b. According to Technical Specifications, MPC values as stated in 10CFR20, Appendix B, Table II, Column 2 are to be used for liquid effluents. Since MPC values were removed from 10CFR20 effective 1/1994, the MPC values are provided as Appendix C of this report.

4

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

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 batch liquid 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 include condensate releases from intermittent blowdown of the steam generators. Tritium releases through the chemical waste basin are also included as continuous releases. 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.

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, are treated as absent.

4.2 Gaseous Effluents Gaseous effluent streams are monitored and sampled in accordahce 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 scintillator and high 5

range GM tubes. The vent is also continuously sampled for iodine and particulates with a charcoal cartridge and filter paper. The filter and charcoal are changed weekly, and analyzed on a multi-channel analyzer in

the laboratory.

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 exceeded. 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, 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 for that batch.

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 "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 .

6

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.

5.0 BATCH RELEASES 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.

6.0 UNPLANNED RELEASES During this reporting period there were no unplanned releases of radioactivity from Salem Unit 1 or 2.

7.0 ELEVATED RADIATION MONITOR RESPONSES During this reporting period, there were no elevated readings on Salem Unit 1 or 2 effluent radiation monitors.

8.0 MODIFICATION TO PREVIOUS RADIOACTIVE EFFLUENT RELEASE REPORTS Our last report (RERR-44) did not include the quarterly Sr-89, Sr-90 and Fe-55 composite data for the second quarter of 1998. RERR-44 also did not include the composite results for tritium released through the chemical waste basin. The chemical waste basin discharge is common to both Salem Units; however, the results are reported in Unit 1 liquid effluent tables. The gaseous effluent Tables lA and lB were updated with additional information that became available after RERR-44 was issued. The revised activities were less than 1% of previously reported total activity and did not affect the reported radiological impact on man. Amended pages to RERR-44 are included at the end of this report .

PART B . GASEOUS EFFLUENTS

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 See Summary Tables 2A-l thru 2B for Salem Unit 1 Operations.

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

PART D. SOLID WASTE See Summary in Table 3.

PART E. RADIOLOGICAL IMPACT ON MAN The calculated individual doses in this section are based on the controlling dose pathways and age groups as described below. The estimated dose represents the maximum radiation dose that could be received by a member of the general public. The popula.tion 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 1998 calendar year. 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 each of the (2) six month reporting intervals.

Organ Pathway only applies to July - December 1998 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 Location Measurement 2S-2 0.3 mile 4.43 mrem/month 5S-l 0.9 mile 3.54 mrem/month These values are interpreted to represent natural background.

They are within the statistical variation associated with the pre-operational program results, which are: 3.7 mrem/month for location 2S-2, and 4.2 mrem/month for location 5S-l.

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. Fo~ Artificial*Island, the major sources of dose are from liquid and gaseous effluents from the Salem and Hope Creek plants .

9

The following doses to members of the public have been calculated for the January - December 1998 reporting period:

2.90 mrem total body 0.344 mrem organ (Liver) 0.195 mrem thyroid Dose to Members of the Public Inside the Site Boundary.

In accordance with the requirements of Technical Specification 6.9.1.8, the dose to members of the public inside the site boundary has been calculated based on the following assumptions:

a. The most. limiting member of the general public is the commercial food vendors.

b. The food vendors spend 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> per day on site.

c. The highest total body dose contribution is direct radiation received from Salem and Hope Creek operation.

d. The food vendors are located near the restricted area boundary

e. Occupancy coincides with batch gaseous effluent discharges For the six month reporting period, the calculated doses are:

3.17E-01 mrem Total Body 1.69E-02 mrem Organ (Liver) 2.99E-02 mrem Thyroid Assessment The dose from liquid and gaseous effluents to the maximum hypothetical individual continues to be well below all applicable limits. Liquid and Gaseous effluents released from Salem increased from previous reporting period due to the startup of 0nit 1 in the 2nd quarter. Liquid effluents remain well below historical operational releases. .

Calculated doses from liquid effluents are due principally to isotopes of iron, cobalt and cesium. Gaseous effluents released from Salem also increased due to the presence of small fuel defects. A portion of the gaseous effluent reported activity is due to a change in data collection method for containment relief process. Calculated doses from gaseous effluent are due* principally to isotopes *of xenon.

The following two trend graphs show the total curies of

liquid and gaseous effluents released from Salem Units 1 and 2 10

for the past 10 years. Calculated doses in the graphs are to the maximum hypothetical individual .

PART I. PROCESS CONTROL PROGRAM (PCP) CHANGES During this reporting period, there were no changes to the Process Control Program.

PART J. ENVIRONMENTAL MONITORING LOCATION CHANGES During the reporting period, the farmer located at 5.2 miles NNE from the plant discontinued milking operations for personal health reasons. Although this location does not meet the requirements for Table 3.12.1 of the Technical Specifications because of distance from the plant, a replacement milk sampling location was found at 7.5 miles NNE from the plant.

PART K. MAJOR CHANGES TO THE WASTE PROCESSING SYSTEM A tubular ultra-filtration (TUF) system was installed as an improvement to the liquid radioactive waste system. The TUF system is common to both Salem Units 1 and 2 and has reduced the total curies released in liquid effluents .

APPENDIX A AMENDMENT TO RERR - 44

PART E. RADIOLOGICAL IMPACT ON MAN The calculated individual doses in this section are based on the controlling dose pathways and age groups as described below. The estimated dose represents the maximum radiation dose that could be received by a member of the general public. 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.

Any s.ingle 3E-8 3E-8 radionuclide not listed above, which decays by alpha emission or spontaneous fission.

Notes:

1. If the identity of any radionuclide is not known, the limiting values for the purposes of this table shall be: 3E-8 uci/ml.

2. If the identity and concentration of each radionuclide are known, the limiting values should be derived as follows: Determine, for each radionuclide in the mixture, the ratio between the quantity present in the mixture and the limit otherwise established in Appendix B for the specific

adionuclued not in a mixture. The sum of such ratios for all the radionuclides in the mixture may not exceed "l" (i.e. "unity") .
