DPR 70 REPORT NO. RERR-5 UNIT NO. l RADIOACTIVE EFFLUENT RELEASE REPORT JULY -

DECEMBER 1978 SALEM NUCLEAR GENERATING STATION Public Service Electric and Gas Company

Introduction SALEM NUCLEAR GENERATING STATION 50-272 UNIT NO. 1 RADIOACTIVE EFFLUENT RELEASE REPORT July 1, 1978 to December 31, 1978 This report, RERR-5, summarizes the release of radioactive materials in liquid, gaseous and solid form from Salem Unit 1 for the period July 1, 1978 to December 31, 1978.

This report was prepared in the format specified in USNRC Regulatory Guide 1.21

  • Release of radioactive materials from the Salem station during the reporting period were within the limits set forth in the Environmental Technical Specifications and calculated radiation exposures to off-site individuals were small fractions of the limits set forth in 10CFR20 and within Appendix I to 10CFR50 requirements.

P78 56 02 EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT RERR 5 A.

SUMMARY

INFORMATION 1.0 Regulatory Limits Symbols utilized in the equations listed below under Sections 1.1 and 1.2 are the same as those used in the Salem Environmental Technical Specifications (ETS).

The symbol Q as explained in Section 2.3.3 of the ETS is the release rate of the gaseous activity in units of curies per second.

The K, L, M and N terms are actually site dependent dose conversion factors.

The equations listed below in Sections 1.1 and 1.2 take into consideration the release point location, building wake effects and physical characteristics of the radionuclides released.

1.1 Fission and Activation Gases -

Gaseous releases from the nuclear units are limited such that at no time will releases of gaseous radioactive materials cause a member of the general public to be exposed to an annual dose rate in excess of 500 mrem to the entire body or 3 rem to the skin in conformance with the requirements of 10CFR20.

Gaseous releases from the units are further restricted such that when releases are averaged over a calendar quarter no member of the general public will be exposed to an annual dose rate in excess of 20 millirads of gamma radiation or 40 millirads of beta radiation.

In addition, it is required that air doses averaged over a twelve month period be less than 40 and 80 millirads for gamma and beta radiation respectively

  • At any instant the release rate of radioactive gases must satisfy the following equations whose basis is 10CFR20.

P78 56 03 2.0 Qtv*Kv < 1 0.33 Qtv*(Lv + 1.1 Nv) < 1 The release limit Q is therefore calculated to be 5.67E4 and 2.65E4 microcuries/sec. for the 3rd and 4th Quarters respectively.

When averaged over a calendar quarter the release rate for radioactive gases must satisfy the following equation.

The basis for these equations is 10CFR50 Appendix. I.

< 1 6.3 Qtv*Mv < 1 The release limit Q is therefore calculated to be 5.67E4 and 2.65E4 microcuries/sec for the 3rd and 4th quarters respectively

  • When averaged over any twelve consecutive month period, the release rate for radioactive gases must satisfy the following equation.

The basis for this equation is 10CFR50 Appendix I.

25 Qtv*Nv < 1 The release limits of radioactive gases for the Salem Nuclear Generating Station are not fixed numbers, but depend upon the radioactive isotopes present in the effluent.

1.2 Iodine and Particulates, Half Life ~ 8 days The regulatory limits for iodines and particulates are listed below.

Releases of iodine and particulates are restricted such that no member of the general public will receive a dose rate in excess of 1.5 rem to the thyroid.

Releases of iodines and particulates are further restricted to*

prevent any member of the general public from receiving a dose rate in excess of 30 mrem in a calendar quarter or 60 mrem in any twelve month period.

The equations which govern these conditions are listed below.

At any instant of time the release rate for radioactive iodines and particulates material with a half life greater then 8 days is limted by the equation below.

The basis for this equation is 10CFR20.

( 1

  • 5 x 1 O 5 ) Ov < 1 P78 60 28 During any calendar quarter the release.limit is governed by the equations listed below.

The basis for these equations is 10CFRSO Appendix. I.

2 curies of I-131 and Qv x 13 x ( 1. s x 1 as) < 1 During any twelve month period radioactive releases should con-form to the following constraints as prescribed by 10CFRSO Appendix I.

25 x (1.5 x 105) x Qv < 1 and 4 curies of I-131 1.3 Liquid Effluents The regulatory limits for radioactive liquids released from the plant are governed by 10CFR20, Appendix B, Table II, Column 2.

In addition, the following limits apply:

The cumulative release of radioactive effluents, excluding tritium and dissolved gases, shall be less than 10 Ci in a calendar quarter for each unit.

The cumulative release of radioactive effluents, excluding tritium and dissolved gases, shall be less than 20 Ci in any twelve consecutive months

  • 2.0 Maximum Permissible Concentrations Regulatory Guide 1.21 requires that the licensee provide the MPC's used in determining allowable release rates for radio-active releases.

We have addressed this question below.

a.

Fission Gases -

MPC values were not used to determine the maximum release rates.

b.

Iodines -

MPC values were not used to determine the e

maximum release rates.

c.

Particulates, Half Lives > 8 days -

MPC limits were not used to determine the maximum release rates.

d.

Liquid effluents -

MPC values as stated in 10CR20, Appendix B, Table 11, Column 2 were used.

P78 60 29 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 the SNGS 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 2.3-3 of the Environmental 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.

These tanks were then recirculated the equivalent of two tank volumes to produce uniform mixing and a sample was extracted and analyzed before any release was made.

Batch releases included releases from the waste monitor tanks, waste monitor hold-up tank, and the chemical and volume control tanks.

Continuous releases included releases from intermittent blowdown of the steam generators.

The predominate isotope detected continued to be cobalt 58

  • Other isotopes detected included Co60, Mn54, and H3 (tritium).

At no time did releases exceed limits.

4.2 Gaseous effluent streams are monitored in accordance with Table 2.3-4 of the Environmental Technical Specifications.

The plant vent is the final release point of all planned gaseous effluents and is continually monitored by four very sensitive Geiger Mueller tubes.

The vent is also continuously sampled for iodine and particulates with a charcoal cartridge and Cesco filter paper connected in series to a low volume air sampler.

The filter and charcoal are changed weekly weather permitting and analyzed on a multichannel analyzer in the laboratory.

Sampling is also performed on all gas decay tanks prior to release to the environment.

The results of these analyses are used as the basis for the cumulative release of gaseous effluents into the environment.

All tritium samples were taken by bubbling gas through water and then counting the tritiated water on a liquid scintillation counter

  • P78 60 37 4.3 5.0 The estimated total error of the reported continuous gaseous releases is within 50%.

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%.

The estimated total error of reported liquid releases is within 25%

  • Batch Releases In order to maintain releases as low as practical as releases approached 1.25 Ci, liquid radwaste was processed through a licensed contractor's demineralizers prior to discharge.

The resins from these demineralizers were transported to an offsite burial facility.

Batch releases of gaseous and liquid effluent are provided in Tables 4A -

4B

  • 6.0 Unplanned Releases There was one unplanned release to an unrestricted area during this reporting period.

This occured when a relief valve on a volume control tank failed to close.

The resultant e

gaseous release included 2.36 Ci of noble gases, l.58E-5 Ci of I-131, l.73E-5 Ci of particulates as Cs-137 and 7.19E-3 Ci of tritium

Liquid Effluents See Summary Tables 2A and 28

  • Part D.

Solid Waste See Summary Table 3

  • P77 77 09 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 the projected 1980 population and 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
  • 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 l.88E-3 mrem.

The calculated population total body dose was 2.70E-2 person~rem

  • The highest organ dose from liquid releases was l.82E-2 mrem to the gastrointestinal tract.

Air Pathways The resulting whole body and skin doses to an individual were calculated to be 4.50E-3 mrem and 2.60E-3 mrem respectively.

The calculated population total body dose was 5.02E-l person-rem.

The average total body dose to the population within fifty miles of the site was 9.38E-5 mrem/person.

Direct Radiation Direct radiation may be estimated by TLD measurements.

One method for comparing TLD measurements is by comparison with preoperational data.

Direct radiation measurements of on site locations averaged only 4.79 mrem/month.

This value is within the statistical variation associated with the preoperational mean value of 4.42 + 0.59 mrem/month.

Maximum Organ Doses The maximum organ doses from radioactive iodines and particulates was 2.28E-2 mrem to the gastro-intestinal tract.

Part F.

Meteorological Data Cumulative joint wind frequency distribution by atmospheric stability class are provided for the third and forth quarters of 1978 as Table 5 and 6.

Tables 7 and 8 provide joint wind frequencies during batch releases for these respective periods
