SUMMARY

Gaseous and liquid effluents for the period remained at a fraction of the Technical Specification limits. Calculations of environmental concentrations based on effluent, Mississippi River flow, and meteor-ological data for the period indicate that consumption by the public of radionuclides attributable to the plant will not exceed the quantity of those radionuclides that result from continuous exposure to the concen-tration values listed in Appendix B, Table 11, of 10CFR20. Gamma rad-iation exposure from noble gases released to the atmosphere represented the critical pathway for the period with a maximum individual dose es-timated to be 3.0 mrem for the six-month period,1974, when a shielding and occupancy factor of two is assumed. Environmental monitoring results ,

confirm that dose via other pathways was not significant.

1.0 EFFLUENTS 1.1 GASEOUS EFFLUENTS TO THE ATMOSPHERE Measured concentrations and isotopic composition of noble gases, radioiodine, and particulate radioactivity released to the atmosphere dur-ing the period 1 January through 30 June 1974, are listed in Table 1.1-1.

A six-month total of 4.2 E +5 curies of noble gases was released during the period with a mximum release rate during any one-hour period of 1.7 E -1 Ci/sec. Release rates during any one month of the period did not exceed 10%

of the Technical Specification limit.

A total of 2.6 curies of I-131 and 3.0 curies of I-133 were released during the six-month period. The highest monthly radioiodine release was 52% of the Technical Specification limit.

Six-month totals of 6.0 E -2 curies of beta-gamma emitters and 1.2 E -6 curies of alpha emitters were released as airborne particulate matter. The highest monthly release of beta-gamma particulate activity did not exceed 12% of the Technical Specification limit.

1.2 LIQUIDS RELEASED TO MISSISSIPPI RIVER A total of 1.7 E +7 liters of radioactive liquid wastes containing 1.3 E +1 curies (excluding tritium) were discharged from the station. These vastes were released at an average concentration of 2.2 E -08 pCi/ml which is 22% of the Technical Specification releases limit for unidentified radioactiv-icy. During the same period,13 curies of tritium and 9.1 E -4 curies of alpha radioactivity were released. Monthly release estimates and principal radionuclides in liquid effluents are given in Table 1.2-1.

The maximum concentration of radioactielty, above background, in the Quad Cities Unit 1/2 discharge canal during the period was computed to be 9.7 E -08 i uC1/ml. This particular release occurred on 10 April 1974.

2.0 SOLID RADIOACTIVE WASTE ,

}

! The total amount of solid waste packaged for disposal was 16,537 cubic feet ,

during the last six-month period. The total amount of radioactivity involved was calculated to be just over 196 curies. Solid radioactive wastes were shipped to either Nuclear Engineering Company, Sheffield, Illinois or Chemical Nuclear '

Services, Bellevue, Washington. Date, volume and radioactivity of each shipment are shown in Table 2.0-1.
