Determination of radioactivity discharge limit to the atmosphere on Bandung nuclear area

Abstract

The determination of radioactivity discharge limits to the atmosphere on Bandung Nuclear Area has been carried out. The purpose is that these values can be used to control the discharge of radioactivity from the TRIGA 2000 reactor stack and the labeled compounds and radiometry laboratory stack in the Area to the atmosphere. The determination method is using PC-CREAM software, assuming the discharge of radioactivity from the stack to the atmosphere occurs under normal conditions and occurs only once. The source terms discussed are radionuclides I-131 and Cs-137, while several the other source terms that were not discussed also contribute to this determination. The initial discharge limits of radioactivity I-131 and Cs-137 from the reactor stack of 4.46E-03 Bq/h and 1.26E+05 Bq/h respectively, while I-131 from the laboratory stack of 2.23E-02 Bq/h. The dose constraint for community members at a distance of 1000 m from the Area is set at 0.15 mSv/y. The parameter needed is source term, reactor building volume, the air flow rate in the reactor stack, stack height, angle and distance between the two stacks, meteorology, topographic roughness, and radionuclide pathway to the community. The result of the calculation obtained the discharge limits of radioactivity for I-131 and Cs-137 from the reactor stack of 7.07E-05 Bq/h and 2.00E+03 Bq/h respectively; and I-131 from the laboratory stack of 3.53E-04 Bq/h.
