SALEM GENERATING STATION RADIOACTIVE EFFLUENT RELEASE REPORT JULY - DECEMBER 1993 INTRODUCTION This report, SGS-RERR-35, 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, 1993 to December 31, 1993.

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 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 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 .

  • 1

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

Unit 1 generated 1,391,149 megawatt-hours of electrical energy (net) during the reporting period.

Unit 2 generated 3,744,544 megawatt-hours of electrical energy (net) during the reporting period.

Results of liquid and gaseous composites analyzed for sr-89, Sr-90 and Fe-55 for the fourth quarter of 1993 were not available for inclusion in this report. The results of these composites will be provided in the next Radioactive Effluent Release Report.

The Sr-89, Sr-90 and Fe-55 analyses for the second half of 1993 (refer to RERR-34) have been completed; amended pages to RERR-34 are included in this report .

' . ' )

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 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.

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 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 scintillator and high 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 .

  • 5

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 monthly 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.

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

6.0 UNPLANNED RELEASES

  • 7.0 During this reporting period there were no unplanned releases.

ELEVATED R-16/R41C CHANNEL RESPONSES During this reporting period, their were no elevated monitors readings on R16/R41C.

a.o MODIFICATION TO PREVIOUS RADIOACTIVE EFFLUENT RELEASE REPORTS Our last report (RERR-34) did not include the quarterly Sr-89, Sr-90 and Fe-55 composite data for the second quarter of 1993. Amended pages to RERR-34 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-1 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 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 "maximum hypothetical 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 the individual: 5.04E-Ol mrem Highest organ dose (GI-LLI): 1.90E+OO mrem Dose to the 6 million individuals living within the 50 mile radius of the plant site:

Total population dose: 7.46E-02 person-rem Average population dose: 1.25E-05 mrem/person

  • 8

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

Total body dose: 1.50E-02 mrem Skin dose: 3.58E-02 mrem Highest organ dose due to radioiodines and particulates with half lives greater than 8 days:

2.14E-02 mrem to the Thyroid.

Dose to the 6 million individuals living within the 50 mile radius of the plant site:

Total population dose: 3.65E-Ol person-rem Average population dose: 6.llE-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 Location Measurement 2S-2 0.3 mile 5.8 mrad/month 5S-1 0.9 mile 6.3 mrad/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 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:

0.723 mrem total body 2.030 mrem organ (GI-LLI) 0.587 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:

a. Such persons are participating or spectators in company softball league
b. 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> per week on site
c. Dose due to airborne pathway(inhalation and immersion)
d. persons are located about 3/4 mile east of plant discharge points (softball fields)
e. occupancy coincides with batch gaseous discharges For the six month reporting period, the calculated doses are:

1.54E-04 mrem Total Body 1.63E-04 mrem Organ (Lung) 1.54E-04 mrem Thyroid

  • 10
  • 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.

Liquid effluents increased slightly from previous reporting periods. Calculated doses are due principally to isotopes of iron, cobalt and cesium. The 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 gaseous and liquid effluents released from Salem units 1 and 2 for the past 6 years. Calculated doses in the graphs are to the maximum hypothetical individual.

PART F

  • METEOROLOGICAL DATA
  • Cumulative joint wind frequency distributions by atmospheric stability class* at the 300 foot elevation are provided for the third and fourth quarters of 1993 in Tables 5 and 6.

PART G. OFFSITE DOSE CALCULATION MANUAL (ODCM) CHANGES During this period, Revision 9 was approved to the SGS off-site dose calculation manual. Revision 9 consisted of updating the ODCM to reflect current Environmental Sampling locations. A copy of the changes made to the ODCM is attached to the end of this report.

PART H. INOPERABLE MONITORS During this period, the following effluent monitors were inoperable for more than 30 days:

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

  • Unit 2 Containment Fan Coil Unit Process Radiation Monitor (2R13B)
  • Unit 2 Containment Fan Coil Unit Process Radiation Monitor (2R13 A,B,C)
  • Unit 2 Liquid Radwaste Disposal Process Radiation Monitor (2R18)
  • Unit 2 Chemical Waste Basin Process Radiation Monitor (2R37)

The 2R18, 2R19 A-D, 2R37 radiation monitors were inoperable from 7/7/88 to 6/91 due to incorrect source decay tables being used. The source decay tables were in error due to an incorrect half-life for Ba-133 being used. The Radiological Health Handbook lists the half-life for Ba-133 as 7.2 and 10.6 years. A half-life for Ba-133 of 7.2 years was used in the source decay tables. This number is incorrect and results in non-conservative radiation monitor system calibrations .

  • 12
  • The 2R13 A-C process monitors were inoperable from 7/7/88 to 10/93 due to the use of incorrect source decay table as stated above.

The 1R19 and 2R19 process monitors could not be returned to operating status within the 30 day time period due to a scheduled refueling outage on Unit 1 and a forced outage on Unit 2.

The R19 process monitors rely on steam generator blowdown flow to maintain operability status.

The 2Rl3B radiation monitor could not be returned to operable status within the 30 day time period due to a cracked weld on the service water discharge valve from the monitor (2SW443). The monitor was inoperable for a total period of 31 days.

The inoperability of the 1R19 & 2R19 monitors are a routine occurrence during extended plant outages.

PART I

  • PART J.

During this reporting period, there were no changes to the Process Control Program.

ENVIRONMENTAL MONITORING LOCATION CHANGES During the reporting period, two additional TLD locations were added to the environmental monitoring sampling program. The new TLD locations, 3.8 miles NW and 6.0 miles ENE of the plant ventilation discharge, were added for program enhancement purposes. The ODCM for Salem and Hope Creek stations was updated to reflect the added locations. A complete list of the current sampling locations is included in the ODCM attached to the end of this report *

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 "maximum hypothetical 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 the individual: 3.39E-Ol mrem Highest organ dose (GI-LLI): 1.32E+OO mrem Dose to the 6 million individuals living within the 50 mile radius of the plant site:

Total population dose: 5.74E-02 person-rem Average population dose: 9.61E-06 mrem/person 8

Salem ODCM Rev. 9

  • APPENDIX E SAMPLE DESIGNATION Samples are identified by a three part code. The first two letters are the power station identification code, in this case "SA". The next three letters are for the media sampled.

AIO = Air Iodine IDM = Immersion Dose (TLD)

APT = Air Particulates MLK = Milk ECH = Hard Shell Blue Crab PWR = Potable Water (Raw)

ESF = Edible Fish PWT = Potable Water (Treated)

ESS = Sediment RWA = Rain Water (Precipitation)

FPB = Beef SWA = Surf ace Water FPL = Green Leafy Vegetables VGT = Fodder Crops (Various)

FPV = Vegetable (Various) WWA = Well Water GAM = Game The last four symbols are a location code based on direction and distance from the site. Of these, the first two represent each of the sixteen angular sectors of 22.5 degrees centered about the reactor site. Sector one is divided evenly by the north axis and

  • other sectors are numbered in a clockwise direction; i.e., 2=NNE, 3=NE, 4=ENG, etc. The next digit is a letter which represents the radical distance from the plant:

s = on-site location A = 0-1 miles off-site E = 4-5 miles off-site F = 5-10 miles off-site B = 1-2 miles off-site G = 10-20 miles off-site c = 2-3 miles off-site H = > 20 miles off-site D = 3-4 miles off-site The last number is the station numerical designation within each sector and zone; e.g., 1,2,3, *** For example; the designation SA-WWA-501 would indicate a sample in the SGS program (SA),

consisting of well water (WWA), which had been collected in sector number 5, centered at 90 1 (due east) with respect to the reactor site at a radical distance of 3 to 4 miles off-site, (therefore, radial distance D). The number 1 indicated that this is sampling station #1 in that particular sector *
