SALEM NUCLEAR GENERATING STATION 50-272 UNIT NO. 1 RADIOACTIVE EFFLUENT RELEASE SUPPORT JANUARY 1, 1977-JUNE 30, 1977 Introduction The Salem Nuclear Generating Station, which went critical on December 11, 1976, has continued in operation through June 30, 1977. During the early part of this reporting period, the station was operating at a capacity of less than 20%, however, during the latter part of the reporting period, the plant has consistently operated near 100% power. In general, the specific activity in each of the waste streams was relatively low.

  • EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT A.

SUMMARY

INFORMATION 1.0 Regulatory Limits 1.1 Fission and Activation Gases Noble Gases Our absolute instantaneous I

limits are: 0.33 Qtv (Lv + 1.1 Nv)< 1 calculated to be 5.50E5 microcuries/sec.

for the period of record Our quarterly 13 Qtv Nv<l limits are: 6.3 Qtv Mv <.l calculated to be 5.92E04 microcuries/sec.

for the period of record and Our twelve month 25 Otv Nv < 1 Limits are: 13 Otv Mv <1 calculated to be 3.07E04 microcuries/sec.

foi the period of record In addition, no gas' decay tank may contain more than 41,000 curies. All symbols used are as stated in Section 2.3.3 of the Environmental Technical Specifications (ETS). The release limits for the Salem Nuclear Generating Station are not fixed numbers, but depend upon the radioactive isotopes present in the effluent.

1.2 Iodines (Same as Part C)

1. 3 Particulates, Half Live"> 8 days The regulatory limit for iodine~ and particulates is:

P77 77 04 1.3 (Continued)

Our absolute instantaneous limit is:

Our quarterly 2 curies of I-131 and limit is: Ov x 13 x (1 . 5 x 1 o5 ) < 1 Our twelve month 2 5 x (1 . 5 x 10 5) Qv < 1 and limit is: 4 curies of I-31 All symbols used are as stated in Section 2.3.3 of the Salem ETS.

1.4 Liquid Effluents The regulatory limits for liquids are governed by 10CFR20, Appendix B, Table II, Column 2.

In addition, the following limits apply:

At no time shall any radwaste tank contain more than 10 Ci of activity. Noble gases and tritium are excluded from this limit.

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.

P77 77 05 2.0 Maximum Permissible Concentrations Provide the MPC's used in determining allowable release rates for concentrations.

a. Fission Gases - MPC values were not used to determine the maximum release rate.
b. Iodines - MPC values were not used to determine the maximum release rates.
c. Particulates, Half Lives ~ 8 days - No MPC limit used to determine the maximum release rates.
d. Liquid effluents - See 10CFR20, Appendix B, Table 11, Column 2.

3.0 Average Energy Provide the average energy E of the radionuclide mixture in releases of fission and activation gases, if applicable.

Release limits are not based upon average energy.

P77 77 06 4.0 Measurements and Approximation of Total Radioactivity 4.1 Liquid effluents are monitored in accordance with Table 2.3-3 of the Salem Nuclear Generating Station Environmental Technical Specifications (ETS). During the period of record, all waste from the chemical drain tank and the laundry and hot shower tanks were routed to the hold-up tanks for monitoring and discharge. These tanks were then recirculated the equivalent of two tank volumes in order to produce uniform mixing and a sample was extracted and analyzed before any release. Although the results of laboratory analysis have indicated the presence of the Isotope F-18, it is suspected that the response of the multi-channel analyzer (MCA) was probably due to the annihilation of a beta particle accompanied by the liberation of 0.511 Mev energy. Since the F-18 isotope also emitts a 0.511 Mev gamma ray it is impossible to discern F-18 from annihilation energy by sole reliance on the MCA. To be conservative F-18 is being reported as present in the effluent released.

4.2 Gaseous effluent streams are monitored in accordance with Table 2.3-4 of the Salem Station ETS. The station's plant vent is the final release point of all planned gaseous effluents.

This location is continually monitored by four very sensitive Geiger-Mueller tubes *and is sampled for iodine and particulates with a charcoal cartridge and Cesco filter paper connected in series to a high volume air sampler. The filter and charcoal are changed weekly and analyzed iri the laboratory.

  • Sampling is also performed on all gas decay tanks prior to release to the environment. The results of these analyses is used as the basis for the cumulative release of gaseous effluent 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% and is primarily due to conservatism in the assumptions of release volumes of liquid holdup tanks.

That is, liquid releases were slightly overestimated.

P77 77 07 5.0 Batch Releases

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

  • 6.0 Abnormal Releases There were no abnormal releases to an unrestricted area during this reporting period.

. Part B. Gaseous Effluents See Summary Tables lA - lC.

Part C. Liquid Effluents See Summary Tables 2A and 2B.

Part D. Solid waste See Summary Table 3.

P77 77 09 Part E. Radiological Impact on Man The calculated doses in this section pertain to those received in unrestricted areas. The population dose impact is based on the expected 1980 population and sites specific data i.e., food production, milk production, feed for milch animals and seafood production, gathered during 1976. It is expected that this data will be representative of 1977 data.

The doses were calculated using methods described using Regulatory Guide 1.109.

Liquid Pathways Doses to individuals in the population- from liquid pathways is primarily the seafood ingestion pathway. The maximum total body dose to an individual was calculated to be 2.22E-4 mrem.

The calculated population total body dose was l.~8E-3 man-rem.

The average total body dose to the population within fifty miles of the site was 2.32E-5 mrem. The highest organ dose from liquid pathways was l.95E-3 mrem to the gastrointestinal tract.

Air Pathways The resulting maximum unrestricted area, whole body and skin dose were calculated to be 5.86E-4 mrem and 9.0lE-4 mrem respectively. The calculated population total body dose was l.74E-2 man-rem. The average total body dose to the population within fifty miles of the site was 3.25E-6 mrem/person.

Direct Radiation The direct radiation resulting from station operation to individuals in unrestricted areas is considered to be negligible.

Maximum Organ Doses The maximum organ doses from radioactive iodines and particulates was 5.78E-4 mrem to the thyroid. The second highest organ dose was calculated to be 7.07E-4 mrem to bone.

Part F. Meteorological Data Cumulative joint wind frequency distribution by atmospheric stability class are provided for the first and. second quarters of 1977 as Table 5 and 6. Tables 7 and 8 provide joint wind frequency during Batch Releases.
