  • INTRODUCTION SALEM GENERATING STATION RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - JUNE 1990 This report, SGS-RERR-28, 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 January 1, 1990 to June 30, 1990.

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 1158 MW(e). 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 MW(e). 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 2,742,500 megawatt-hours of electrical energy (net) during the reporting period.

Unit 2 generated 2,157,320 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 second 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 last half of 1989 (refer to RERR-27) have been completed; amended pages to RERR-27 are included in this report .

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

  • 2.0 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).

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. ~PC 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. 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.

4.0 MEASUREMENTS AND APPROXIMATION OF TOTAL RADIOACTIVITY 4.1 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. The preponderant gamma emitting isotopes detected in sampling were Co-58, co-60 and Mn-54. Specific activity 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 Table 4.11-1 of the Technical Specifications are achieved or exceeded.

Nuclides existing at concentrations below the achieved detection limit are treated as being present. Nuclides for which no activity was detected while meeting the required sensitivity values (LLDs) are treated as not being present.

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 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

  • 5

The detection requirements of Tables 4.11-1 and 4.11-2 of the Technical Specifications are achieved or exceeded. Isotopes existing at concentrations below the achieved detection limit are treated as not being present.

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 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% .

  • 6

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.

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-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.

7.0 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 Rl6/R41C readings were quantified and treated as continuous releases. It was assumed that they were Xe-133 since it the preponderant isotope released. The releases due to the elevated readings were thus included in Tables lB-1 and lB-2.

8.0 MODIFICATION TO PREVIOUS RADIOACTIVE EFFLUENT RELEASE REPORTS Our last report (RERR-27) did not include the quarterly Sr-89, Sr-90 and Fe-55 composite data for the last half of 1989.

Amended pages to RERR-27 are included at the end of this report.

PART B. GASEOUS EFFLUENTS See Summary Tables lA-1 through lC for Salem Unit 1 Operations.

  • PART C. LIQUID EFFLUENTS See Summary Tables 2A-1 through 2C for Salem Unit 1 Operations.

See Summary Tables 2A-2 through 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., ~ood 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. The total body dose to an individual was calculated to be 2.82E-Ol mrem. The calculated highest organ dose from liquid releases was l.07E+OO mrem to the GI-LLI. The calculated population total body dose was 9.77E-02 person-rem. The calculated average total body dose to the population within fifty miles of the site was l.64E-05 mrem/person *

  • 8

Air Pathways 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 radioiodine an particulates with at greater than eight day half-life was 1.13E-02 mrem to the thyroid. The calculated population total body dose was 4.0SE-01 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 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 4.6 and 4.1 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 first and second quarters of 1990 in Tables 5 and 6.

PART G. ODCM CHANGES During the reporting period between January 1, 1990 and June 30, 1990, the Salem ODCM was revised. Revision 6 was subsequently SORC approved on April 11, 1990. In accordance with Salem Technical Specifications 6.9.1.11 and 6.14, information on the changes is being provided. The current revision 6 of the ODCM includes changes which 9

(1) reflect more current release information to ensure

  • (2) that recommended default alarm setpoints for liquid releases are representative of the current releases; change the impact reflecting the use of dose equations (i.e. changing the requirement to use the ODCM dose equations from "may use" to "shall use") ; and (3) are in response to Technical Evaluation Report (TER), SIM-20-89.

Below is a breakdown of the revisions made to the revised ODCM:

Dose factors in equations 2.6 and 2.11 on pages 22 and 26 were changed to include subscripts for the Ri dose factors in order to avoid any possible misinterpretation of which dose factors should be used for a given pathway.

A footnote was also added to page 36 stating that no public drinking or irrigation water samples are taken for the REMP program as these pathways are not directly affected by liquid discharges from Salem .

  • Figure 1-3 on page 40 was also revised to provide a more simplified illustration of the solid radwaste treatment system. The previous figure was too complex for quick reference and did not depict current treatment methods.

Figure 2-4 was revised to include "inhalation" to the pathway list for the infant age group to insure that all pathways are analyzed for this controlling age group.

The direction and distance to the nearest dairy/residence was a~so corrected in Table 2-4 on page 51.

Equation 2.16 on page 30 was corrected by removing the summation sign before the term (Ci*SFj) since this equation is to be used for one radionuclide and one pathway. The definition of cij was also added to equation 2 .16.

The words 11 * *

  • and the child age group is controlling for the vegetation pathway " were removed from the first sentence on page 27. The words "and pathway " were removed from "only the controlling age group and pathway as identified in Table 2-4" The reason for these revisions was to ensure that dose analyses are performed for all pathways and not just controlling pathways *
  • 10

The dose conversion factor for Ce-141 in the child vegetation pathway was corrected in Table 2-5. No dose calculations have been affected as Ce-141 has not been identified in any gaseous effluents.

Per the requirements of Technical Specification 6.9.1.11, a copy of the revised ODCM is attached for NRC records.

These changes will not reduce the accuracy or reliability of the dose calculations or the setpoint calculations ~s outlined in the ODCM.

PART H. INOPERABLE MONITORS Between the period of January 1, 1990 and June 30, 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 of why the inoperability was not corrected in a timely manner is given below :

On April 7, 1990, the number 14 steam generator blowdown line flow indicator was declared inoperable because of a malfunction in the flow indication. Unit 1 entered an outage between April 9 and June 7 for Safety

  • Injection Pump related work. During the outage, work was performed to bring the monitor back into service.

The initial work order was completd on April 10. The operability retest required to return the monitor to service could not be performed within the 30 day limit due to the unavailability of steam generator blowdown process flow. The monitor was out of service for 59 days.

Steam Generator process flow is not available during modes 5 and 6. The plant did not reach a mode in which the retest could' be performed until June 5. This was well after the 30 day requirement. The cause of the monitor being out of service for greater than 30 days was due to plant conditions which would not allow a test of monitor operability to be performed.

During this reporting period, the A,B,C and D channels of the Salem Unit 2 steam generator blowdown radiation monitors exceeded the Technical Specification 3.3.3.8 thirty day inoperability limit. Channel 2R19C exceeded the thirty day limit on April 21, 1990. Channels A,B and D exceeded the thirty day limit on April 30, 1990.

All four monitors became inoperable due to the loss of 11

secondary system blowdown flow which was due to the Unit 2 March 30 refueling outage.

The Salem Unit 2 22 steam generator blowdown flow monitor was declared inoperable on April 9, 1990 due to faulty flow indication. Unit 2 was shutdown between March 30 and June 22 for a refueling outage. During the outage, work was performed to bring the monitor back into service. The initial work order was completed on April 19. The operability retest required to return the monitor to service could not be performed within the 30 day limit due to the unavailability of steam generator blowdown flow during the outage. The retest was performed on June 26 after the Unit start up. This retest failed and another work order was issued to replace the flow transmitter. The Unit was then shutdown on June 27 for an MSIV outage. The transmitter was replaced and the monitor was declared operable on July 24 while in mode 3. The monitor was inoperable for 106 days.

Steam generator blowdown process flow is not available during modes 5 an 6. The plant did not reach a mode in which the initial retest could be performed until June 26. This was well after the 30 day requirement. The cause of the monitor being out of service for greater than 30 days was due to plant conditions which would not allow a test of monitor operability to be performed.

  • 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 l.lBE-01 mrem. The calculated highest organ dose from liquid releases was 5.BBE-01 mrem to the GI-LLI. The calculated population total body dose was 6.65E-02 person-rem. The calculated average total body dose to the population within fifty miles of the site was l.llE-05 mrem/person.

Air Pathway The resulting total body and skin doses to an individual were calculated to be l.37E-02 mrem and 3.22E-02 mrem respectively. The calculated highest organ dose due to radioiodine and particulates with a greater that eight day half-life was 2.35E-02 mrem to the thyroid. The calculated population total body dose was 7.0lE-01 person-rem. The calculated average total body dose to the population within fifty miles of the site was l.l7E-04 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 A~ificial 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 4.6 mrads/month, respectively. The values for stations 25-2 and 55-1 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 thus .. pe concluded that there is no measurable dose to any offsite location from direct radiation.

Part F. MITEOROLQGICAL PATA cumulative joint wind frequency distributions by atmospheric stability class at the JOO foot elevation are provided for the third and fourth quarters of 1989 in Tables 5 and 6.
