1.2 Gaseous Effluents All gaseous effluents are treated as ground level releases and are considered to be "long-term" as discussed in NUREG-
- 0133, Section 3.3, page 8.
This includes the containment purge and 'gaseous decay tank releases as well as the normal ventilation system and condenser vacuum exhaust releases.
All releases are either greater than 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> in duration or are made at random, not depending upon atmospheric condi-tions or time of day.
The releases a'e lumped together and calculated as an entity.
The historical annual average X/Q is therefore used throughout this manual for all gaseous effluent set-point and dose calculations.
Airborne releases are further subdivided into two, subclasses:
1.2.1 Iodine,131, Iodine 133, Tritium and Radionuclides in Particulate Form with Half-Lives Greater than Ei ht
~Da s In this model, a critical location is identified for assessing the maximum exposure to an individual for the various pathways and to critical organs.
Infant exposure occurs through inhalation and any actual milk pathway.
Child, teenager and adult exposure derives.
from inhalation, consumed leafy vegetable and produce
- pathways, and any actual milk and meat pathways.
Dose to each of.the seven organs listed in.Regulatory Guide 1.109,(bone, -liver, total body, thyroid, kidney, lung and GI-LLI) are computed from individual nuclide contributions in each sector.
The largest of the organ doses in any sector is compared to 10 CFR 50, Appendix I design objectives.
This dose calculation is performed monthly for all age groups.
As necessary, the release rates of these nuclides will be converted to dose rates for comparison to the limits of 10 CFR 20.
