SALEM GENERATING STATION RADIOACTIVE EFFLUENT RELEASE REPORT JULY - DECEMBER 1991 INTRODUCTION This report, SGS-RERR-31, 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, 1991 to December 31, 1991.

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 4,367,423 megawatt-hours of electrical energy (net) during the reporting period.

Unit 2 generated 3,294,730 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 1991 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 first half of 1991 (refer to RERR-30) have been completed; amended pages to RERR-30 are included in this report .

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 mrems to the total body or any organ (except the thyroid, which shall be limited to less than or equal to 75 mrems).

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, iodines, or particulates.
b. MPC values as stated in 10CFR20, Appendix B, Table II, Column 2 were used for liquids.
c. The MPC value used for dissolved or entrained noble gases 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 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 "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 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 .

    • 6

The estimated total error of reported solid releases is

  • s.o within 25%.

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 During this reporting period there was one unplanned release. On November 22, 1991 while the Unit 2 plant was in a refueling outage a maintenance activity caused a small release of airborne radioactivity into the containment building (LER 91-020-00). The release was detected by the plant ventilation monitors and included in the data presented in Table 4B-2. No personnel contamination occurred as a result of this release.

7.0 ELEVATED R-16/R41C CHANNEL RESPONSES During this reporting period, their were no elevated monitors readings on Rl6/R41C.

8.0 MODIFICATION TO PREVIOUS RADIOACTIVE EFFLUENT RELEASE REPORTS Our last report (RERR-30) did not include the quarterly Sr-89, Sr-90 and Fe-55 composite data for the second quarter of 1991. Amended pages to RERR-30 are included at the end of this report.

Additionally, calculational errors were found after RERR-30 was submitted. The corrected pages are included at the end of this report. The reported doses were not significantly affected.

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.

c.

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

See Summary Tables 2A-2 thru 2C 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 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: 3.18E-Ol mrem Highest organ dose: 1.63E+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: 6.94E-02 person-rem Average population dose: 1.16E-05 mrem/person

  • 8

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

Total body dose: 3.66E-03 mrem Skin dose: 8.93E-03 mrem Highest organ dose due to radioiodines and particulates with half lives greater than 8 days:

7.17E-03 mrem to the Thyroid.

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

Total population dose: 2.02E-Ol person-rem Average population dose: 3.38E-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 28-2 0.3 mile 5.0 mrad/month 58-1 0.9 mile 4.7 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 28-2, and 4.2 mrad/month for location 58-1.

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:

0.752 mrem total body

1. 740 mrem organ (GI-LLI) 0.336 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 West of plant discharge points (baseball fields)
  • occupancy coincides with batch gaseous discharges For the six month reporting period, the calculated doses are:

3.06E-05 *mrem Total Body 3.25E-05 mrem Organ 3.06E-05 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 are about the same as 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.

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 1991 in Tables 5 and 6.

PART G. OFFSITE DOSE CALCULATION MANUAL (ODCM) CHANGES During this period, there were no changes to the SGS ODCM.

PART H. INOPERABLE MONITORS During this period, the following e*ffluent monitors

  • Unit 1 Containment Fan Cooling Unit Process Monitors (1R13 A,B,C,D,E)
  • Unit 2 Containment Fan Cooling Unit Process Monitors (2R13 A, B, C)

These monitors could not be returned to operating status within the 30 day time period due to a forced shutdown and subsequent refueling outage on Unit 2. The Unit 1 monitors are declared inoperable due to Unit 2 Circulating Water out of service during the refueling outage. The service water discharge of Unit 1 is cross connected with the Unit 2 circulators. The Unit 1 Rl3 monitor setpoints are based on the dilution of the circulating water. The monitors will be restored to service following completion of the current outage.

Additionally the Chemical Waste Basin Process Monitor (2R37) was inoperable for more than 30 days (LER 91-011-00). In July 1991 it was discovered that a non-conservative setpoint had been in place for the Chemical Waste Basin Process Monitor since June of 1985. The reason for the non-conservative setpoint was a change in Clearwell Pump design which resulted in a higher capacity for the pumps. The new design information was not transmitted to the proper documents which resulted in the new design information not being updated. Procedural changes have been made to prevent the reoccurrenc"e of this incident. Investigation of this occurrence concluded that no regulatory limits were exceeded due to the non-conservative setpoint being used *

See summary Tables 2A-2 thru 2C 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 cal~ulations 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.

Liguid 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: 2.94E-Ol mrem Highest organ dose: 1.34E+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: 1.0SE-01 person-rem Average population dose: 1.76E-05 mrem/person 8
