"SALEM GENERATING STATION RADIOACTIVE EFFLUENT RELEASE REPORT JULY - DECEMBER 1990 INTRODUCTION This report, SGS-RERR-29, 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, 1990 to December 31, 1990.

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.

This 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.

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

Unit 1 generated 3,209,274 megawatt-hours of electrical energy (net) during the reporting period.

Page 2

Unit 2 generated 4,084,649 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 1990 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 1990 (refer to RERR-28) have been completed; amended pages to RERR-28 are included in this report.

.O 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 1CFR20, Appendix B, Table II, Column 2 were used for liquids.

c. MPC value used for dissolved or entrained noble gases was 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.

MEASUREMENTS AND APPROXIMATION OF TOTAL RADIOACTIVITY 4.1 Liquid effluent streams are monitored and sampled in accordance with Table 4.11-1 of the Technical Specifications. During the period of record, all wastes from the chemical drain tank, 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 tanks and the chemical and volume control system.

Continuous liquid releases are defined as condensate releases from intermittent blowdown of the steam generators. The preponderant gamma emitting nuclides detected in sampling were Co-58, Co-60 and Mn-54.

Specific activities from analyses were multiplied by the volume of effluent discharged to the environment in order to calculate the total liquid activity discharged.

4.2 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

• Page 5

range GM tubes. Also, the vent is sampled continuously for iodine and particulates with a carbon cartridge and filter*

paper connected in series to a low volume air sampler. The filters are changed weekly and analyzed on a multi-channel analyzer. 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 (LLDs) of Tables 4.11-1 and 4.11-2 of the Technical Specifications are achieved or exceeded. Radionuclides for which no activity was detected while meeting the 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 nuclide detected are multiplied by the total vent flow volume for the entire sampling period in order to calculate the normal continuous release of radioactivity through the plant vent.

Slightly elevated plant vent radiation monitor readings are treated as continuous releases. The monitor's 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 nuclide 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 are 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 The estimated total error of reported liquid releases is within 25%.

Page 6

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 (MDA) are not included since error estimates at the MDA are not defined.

The estimated total error of reported solid releases is within 25%.

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

• O ELEVATED R-16/R41C CHANNEL RESPONSES During this reporting period, the plant vent radiation monitors indicated slightly elevated readings on several occasions. As indicated above, elevated R16/R41C readings were quantified and treated as continuous releases. It was assumed that they were Xe-133, since it the preponderant nuclide released. The elevated readings are included in Tables lB-1 and lB-2.

8.0 MODIFICATION TO PREVIOUS RERRS Our last report (RERR-28) did not include the second quarter Sr-89, Sr-90 and Fe-55 composite data for the first half of 1990. Amended pages to RERR-28 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.

~art c. 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 milch 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. The total body dose to an individual was calculated to be 1.59E-Ol mrem. The calculated highest organ dose from liquid releases was 1.15E+OO mrem to the GI-LLI. The calculated population total body dose was 8.20E-02 person-rem. The calculated average total body dose to the population within fifty miles of the site was 1.37E-05 mrem/person.

Air Pathways The resulting total body and skin doses to an individual were calculated to be 6.84E-03 mrem and 1.64E-02 mrem respectively. The calculated highest organ dose due to radioiodines and particulates with at greater than eight day half-life was 3.27E-03 mrem to the thyroid. The calculated population total body dose was 1.50E-Ol person-rem. The calculated average total body dose to the population within fifty miles of the

• site was 2.SOE-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.

TLDs at onsite locations 2s-2 and ss-1, which are 0.3 miles and 0.9 miles from the point of origin, averaged 4.9 and 4.2 mrads/month respectively. The values for stations 2S-2 and SS-1 are within the statistical variation associated with the preoperational program results.

It should be noted the nearest resident is 3.5 miles away. It can thus be concluded that there is no measurable dose to any offsite location from direct radiation.

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 1990 in Tables 5 and 6.

art G. ODCM CHANGES During the report period, there were no changes to the Salem Generating Statio*n Off-Site Dose Calculation Manual.

Part H. INOPERABLE MONITORS Between the period* of July 1, and December 31, 1990, there were three instances of radioactive effluent monitors being out of service for periods greater than 30 days. Per Salem Technical Specification 3.3.3.8, an explanation for the inoperability not being corrected within 30 days is given below:

On August 2, 1990 the number 14 steam generator blowdown radiation monitor (l-R19D) flow indicator was determined inoperable due to positive flow indication while Unit 1 was in cold shutdown and blowdown flow secured. Maintenance work was done on the flow indicator on August 17. The operability retest could not be performed within 30 days of the monitor being declared inoperable per Technical Specification 3.3.3.8, due to the shutdown with no steam generator blowdown flow. On September 4, 1990, during plant heatup, the flow indicator was successfully tested for

• operability

• Page 9

On June 23, 1990, the number 22 steam generator blowdown radiation monitor {2-Rl9B) was determined to be inoperable due to erratic response of the meter. Maintenance work was done on the monitor on June 27. The operability retest could not be performed within 30 days of the monitor being declared inoperable per Technical Specification 3.3.3.8, because Unit 2 was shutdown with no steam generator blowdown flow. On September 5, 1990, with the plant at power, the radiation monitor was successfully tested for operability.

on June 28, 1990, the number 21, 23, and 24 steam generator blowdown radiation monitor {2-R19A, c, D) flow indicators were determined to be inoperable due to indications of low flow. Unit 2 was in a maintenance shutdown with steam generator blowdown secured. Technical Specification 3.3.3.8 requires that the steam generator blowdown radiation monitors be operable at all times. No corrective maintenance work was required on the flow indicators. An operability retest could not be performed within 30 days of the monitors being declared inoperable per Technical Specification 3.3.3.8 because Unit 2 was shutdown with no steam generator blowdown flow. on September 5, 1990, with the plant at power, the radiation monitors were successfully tested for operability *

• f Liauid Pathways Doses to individuals in the population from liquid releases are primarily from the seafood ingestion pathway. The total body dose to an individual was calculated to be 3.04E-Ol mrem. The calculated highest organ dose from liquid releases was 1.13E+OO mrem to the GI-LLI. The calculated population total body dose was 9.SOE-02 person-rem. The calculated average total body dose to the population within fifty miles of the site was 1.64E-05 mrem/person .

. Air Pathway The resulting total body and skin doses to an individual were calculated to be 3.04E-03 mrem and 7.41E-03 mrem respectively. The calculated highest organ dose due to radioiodines and particulates with a greater than eight day half-life was 1.13E-02 mrem to the thyroid. The calculated population total body dose was 4.05E-Ol person-rem. The calculated average total body dose to the population within fifty miles of the site was 6.78E-05 mrem/person.

Direct Radiation Direct radiation may be estimated by Thermoluminescent dosimetric (TLD) measurements. One method for comparing TLD measurements is by omparison with preoperational data. It should be noted that the TLDs easure direct radiation from both the Salem and Hope Creek Generating Stations at Artificial Island.

TLDs at onsite locations 2S-2 and 5S-1, which are 0.3 miles and 0.9 miles from the point of origin, averaged 4.6 and 4.1 mrads/month respectively. The values for stations 2s-2 and 5S-l are within the statistical variation associated with the preoperational program results.

It should be noted that the nearest resident is 3.5 miles away. It can be concluded that there is no measurable dose to any.offsite location from direct radiation.
