a) During any calendar quarter: Less than or equal to 1.5 mRem to the total body and to less than or equal to 5 mRem to any organ, and b) During any calendar year: Less than or equal to 3 mRem to the total body and to less than or equal to 10 mRem to any organ.
- c. Total Dose
- 1) The dose or dose commitment to any member of the public, due to releases or radioactivity and radiation, from uranium fuel cycle sources shall be limited to less than or equal to 25 mRem to the body or any organ (except the thyroid, which shall be limited to less than or equal to 75 mRem) over 12 consecutive months.
- 2. Allowable Concentrations

SUPPLEMENTAL INFORMATION
- b. Liquid Effluents
- 1) The concentration of radioactive material released from the site shall be limited to ten (10) times the concentrations specified in 10 CFR Part 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to the following:
Nuclide DWC
( Ci/mL)
Kr-85m 2.00E-04 Kr-85 5.00E-04 Kr-87 4.00E-05 Kr-88 9.00E-05 Xe-131m 7.00E-04 Xe-133m 5.00E-04 Xe-133 6.00E-04 Xe-135m 2.00E-04 Xe- 135 2.00E-04 Ar-41 7.00E-05
- 3. Average Energy
- 1) Not applicable - average energy is no longer used to determine dose to the public.
- 4. Measurements and Approximations of Total Radioactivity
- a. Gaseous Effluents
- 1) Containment Vent and Purge System is sampled by grab sample, which is analyzed for principal gamma emitters and H-3.
- 2) Main Vent Stack is sampled by grab sample, which is analyzed for principal gamma emitters and H-3.
- 3) Standby Gas Treatment System is sampled by grab sample, which is analyzed for principal gamma emitters.
- 4) All release types as listed in 1 and 2 above are sampled at the vent stack, and those listed in 3 above are sampled at the Standby Gas Treatment System whenever there is flow. These effluents are continuously sampled by charcoal cartridge and particulate filter paper, which are analyzed for iodines and principal gamma emitters. Particulate filter papers are composited and analyzed for gross alpha, Sr-89 and Sr-90. Noble gases, gross beta and gamma are continuously monitored by noble gas monitors for the vent stack and the standby gas treatment system.
- 5) The LaSalle County Station estimate of 16.85 Ci/Unit/year of C-14 (as total C-14 released) is based upon a normalized C-14 production rate of 5.1 Ci/GWt-yr, a gaseous release fraction of 0.99, a reactor power rating of 3546 MWt (per Unit) and equivalent full power operation of 343.5 days (per Unit).
- b. Liquid Effluents
- 1) Batch waste release tanks are sampled each batch for principal gamma emitters, 1-131, dissolved and entrained noble gases, H-3, gross alpha, Sr-89, Sr-90 and Fe-55.
