Introduction SALEM NUCLEAR GENERATING STATION 50-272 UNIT NO. l RADIOACTIVE EFFLUENT RELEASE REPORT January 1, 1980 to June 30, 1980 This report, RERR-8, summarizes the release of radioactive materials in liquid, gaseous and solid form from Salem Unit l for the period January 1, 1980 to June 30, 1980.

This report

.was prepared in the format specified in USNRC Regulatory Guide 1.21.

Release of radioactive materials from the Salem station dur-ing the reporting Period were within the limits set forth in the Environmental Technical Specifications and calculated radiation exposures to off-site individuals were small frac-tions of the limits set forth in 10CFR20 and within Appendix I to lOtFR50 and 40CFR190 requirements.

The unit generated 4,710,530 megawatts-hour of electrical energy (0.54 gigawatt-year) during the reporting period.

SUMMARY

INFORMATION 1.0 Regulatory Limits Symbols utilized in the equations listed below under Sec-tions 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 conver-sion 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.

In addition 40CFR190 regulations require that the annual.

dose equivalent does not exceed 25 mrem to the whole body or any organ. (except the thyroid which is limited to 75 mrern).

1.1 Fission and Activation Gases Gaseous releases from the nuclear units are limited such that at no time will releases of gaseous* radioactive mater-ials 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 rnillirads 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.

2.0 Otv*Kv.S. 1 0.33 Otv*(Lv + 1.1 Nv) < 1 M PB 0 1 T 18 I

I I

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

The basis for these equations is 10CFRSO Appendix I.

13 Otv*Nv

< 1 6.3 Otv*Mv < 1 The release limit Q is therefore calculated to be 5.30E04 microcuries/sec for the 1st and 2nd 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 10CFRSO Appendix I.

25 Otv*Nv < 1 13 Otv*Mv < 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 particu~ates are listed below.

The release rates of iodine and particulates are restricted such that no member of the general public will receive a dose at a rate in excess of 1.5 rem/yr. 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 equation~ 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 than 8 days is limited by the equation below.

The b~sis for this equation is 10CFR20.

I During any calendar quarter the release limit is governed by the equations listed below.

The basis for these equations is 10CFR50 Appendix I.

2 curies of I-131 and Qv x 13 (1.5 105) < l During any twelve month period radioactive releases should conform to the following constraints of 10CFR50 Appendix I.

25 x (1.5 x lOs) x bv < l 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 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.

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.

Technical Specifications require these tanks to be recirculated the equivalent of two tank volumes to produce uniform mixing.

Afterwards, a sample is extracted and analyzed before any releases are 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 stream generators.

T~e predominate gamma emitting isotopes detected included Co60, Mn54, Co58, and Cesium 137.

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 Specifica-tions.

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 Cesco charcoal.cartridge and filter paper con-nected 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 and containment purges 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.

4.3 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%.

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

4B.

6.0 Unplanned Releases There were no unplanned releases to an unrestricted area during this reporting period.

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 i~ based on the projected 1980 pop-ulation and historical site specific data i.e., food pro-duction, milk production, feed for ~ilch animals and sea-food production.

The doses were calculated using methods described in Reg-ulatory Guide 1.109 and represent calculations for the six month reporting interval.

Doses from batch and continuous releases were calculated using the meteorological disper-sion coefficient X/Q for the six month reporting interval.

Liquid Pathways Doses to individuals in the population from liquid re-leases are primarily from the seafood ingestion pathway.

The total body dose to an individual was calculated to be 2.69E-3 mrem.

The calculated population total body dose was l.26E-2 person-rem.

The highest organ dose from liquid releases was 7.79E-3 mrem to the gastrointestinal tract.

Air Pathways The resulting whole body and skin doses to an individual were calculated to be 4.31E-3 mrem and 3.93E-3 mrem re-spectively.

The calculated population total body dose was 4.76E-l person-rem.

The average total body dose to the population within fifty miles of the site was l.03E-4 mrem/person.

Direct Radiation Direct radiation may be estimated by TLD measurements.

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

TLD measurements on site near the Service Water pumps -(location llSl) and near the Cir-culating Water pumps (location lOSl) averaged 18.3 and 9.1 mrads/months, respectively, apparently due to trace activ-ity in the Refueling Water Storage Tank.

TLD's at onsite locations 2Sl and 5Sl which are 0.3 miles and 0.9 miles from the reactor containment, averaged 5.73 and 4.75 mrads/month respectively.

The values for station 2Sl are within the statistical variation associated with the preoperation program results which was 4.57 + 2.00.

Values at onsite location 5Sl were slightly higher than preoperation value of 3.91 + 0.62.

It should be noted that the nearest resident is 3.5 miles away.

It can thus be concluded that there was no measurable dose to any offsite locations from direct radiation.
