SALEM GENERATING STATION RADIOACTIVE EFFLUENT RELEASE REPORT I JULY - DECEMBER 1996 INTRODUCTION This report, SGS-RERR-41, summarizes information pertaining to the releases of radioactive materials in liquid, gaseous and I solid form from the Salem Generating Station (SGS) Units 1 and 2 for the period July 1, 1996 to December 31, 1996.

This semiannual Radioactive Effluent Release Report (RERR) is suomitted 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 I 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 I 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 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 release rates for fission gases, iodines, or particulates from gaseous releases.
b. MPC values as stated in 10CFR20, Appendix B, Table II, Column 2 were used for liquids.

l

c. The MPC value used for dissolved or entrained I 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 batch liquid wastes from the I 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 I 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 I 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 estima'te 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 I

~

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 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 I weekly, and analyzed on a multi-channel analyzer in the laboratory.

5

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 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 g below the Technical Specification detection limits a (LLDs) are treated as being present. Radionuclides for which no activity was detected, while meeting the g required LLDs, are treated as absent. 3 Continuous Mode gaseous releases are quantified by g routine (monthly or weekly) sampling and isotopic 3 analyses of the plant vent. Specific activities for each isotope detected are multiplied by the total vent a flow volume for the entire sampling period in order to g estimate the normal continuous release of radioactivity through the plant vent.

Slightly elevated plant vent radiation monitor readings I

are treated as continuous releases. The manitors 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 g discharge. Specific activities for.each isotope are E ,

multiplied by the total volume of gas discharged for l that batch.  !

l l

I Elevated plant vent radiation monitoring system readings while the channel is in an alarm state are g i treated as batc. mode releases. If specific activity gI 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 Tctal 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-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 were no unplanned releases of radioactivity from Salem Unit 1 or 2.

I 7.0 ELEVATED RADIATION MONITOR RESPONSES During this reporting. period, there were no elevated monitors readings on R16/R41C.

8.0 MODIFICATION TO PREVIOUS RADIOACTIVE EFFLUENT RELEASE REPORTS I Our last report (RERR-40) did not include the quarterly Sr-89, Sr-90 and Fe-55 composite data for the second quarter of 1996. Amended pages to RERR-40 are included at the end I of this report.

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 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 1996 calendar year. Individual doses from batch and continuous re W ses were calculated using the annual average historic meteorological dispersion coefficients as described in the Offsite Dose Calculation Manual. Population doses E were calculated using the meteorological dispersion 5 coefficients for the (2) six month reporting intervals.

One method for comparing TLD I 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 I Artificial Island, as well as natural background radiation.

TLD data for the six montu reporting period is given below:

TLD Location Measurement 2S-2 0.3 mile 4.1 mrem / month SS-1 0.9 mile 3.3 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 SS-1.

Total Dose 40CFR190 limits the total dose to members of the public 1 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.

- 9

I The following doses to members of the public have been calculated for the January - December 1996 reporting period:

0.275 mrem total body 0.662 mrem organ (GI-LLI) 0.026 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 i.'m general public is the commercial food vendors.
b. The food vendors spend 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. 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 E doses are- 5 3.30Et00 mrem Total Body g 5.50E-03 mrem Organ (Lung) E 5.50E-03 mrem Thyroid Assessment Liquid and Gaseous effluents released from Salem decreased from previous reporting periods due to the extended shutdown of both units. Calculated doses from liquid effluents are due principally to isotopes of iron, cobalt and cesium. The l dose from liquid and gaseous effluents to the maximum hypothetical individual were well below all applicable limits.

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

The Radiation Monitoring system instrumentation listed above have been inoperable during this report period due to the extended maintenance outage on Salem Unit 1& 2. The Unit's have been shutdown since the 2nd quarter of 1995.

Maintenance items conducted during this time period include the complete replacement of the Unit 1 and 2 Plant Vent Radiation Monitoring System; the replacement of Unit 1 Steam Generators, and extensive maintenance on the Unit 2 Waste Gas monitoring system. Additionally, the inability to establish sample stream flow due to I the extended outage prevented restoring some of the radiation monitors to service.

On July 17, 1996, an engineering review determined that the sample flow to the Chemical Waste Basin Process Radiation Monitor was not adequate under certain plant 1 conditions. The conditions of inadequate flow would occur when the Delaware River was at low tide and only one discharge pump was in service. Licensing Event Report 96-006 provides additional information on this i occurrence. A design change to the sample line is required to correct the problem. The design change is expected to be complete during the next reporting I period.

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

I PART J. ENVIRONMENTAL MONITORING LOCATION CHANGES During the reporting period, there were no changes to the environmental monitoring sampling program.

PART K. MAJOR CHANGES TO THE WASTE PROCESSING SYSTEM I

During this reporting period, there were no major changes to the radioactive waste processing system.

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, feod 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. l Population doses were calculated using the actual 5 meteorological dispersion coefficients for the six month reporting interval.
