Supplemental Information

1. Regulatory Limits

a. Gaseous Effluents

1) The air dose due to noble gases released in gaseous effluents,from each reactor unit, from the site shall be limited to thefollowing:

a) During any calendar quarter: Less than or equal to 5mrad for gamma radiation and less than or equal to 10mrad for beta radiation, and

b) During any calendar year: Less than or equal to 10 mradfor gamma radiation and less than or equal to 20 mradfor beta radiation.

2) The dose to an individual from radioiodines and radioactivematerials in particulate form, and radionuclides, other thannoble gases, with half-lives greater than eight days ingaseous effluents released, from each reactor unit, from thesite shall be limited to the following:

a) During any calendar quarter: Less than or equal to 7.5mRems to any organ, and

b) During any calendar year: Less than or equal to 15

mRems to any organ.

b. Liquid Effluents

1) The dose or dose commitment to an individual from radioactivematerials in liquid effluents released, from each reactorunit, from the site shall be limited:

a) During any calendar quarter to less than or equal to 1.5mRem to the total body and to less than or equal to 5mRem to any organ, and

b) During any calendar year to less than or equal to 3 mRemto the total body and to less than or equal to 10 mRemto any organ.

c. Total Dose

1) The dose or dose commitment to any member of the public, dueto releases or radioactivity and radiation, from uranium fuelcycle sources shall be limited to less than or equal to 25mRem to the body or any organ (except the thyroid, which shallbe limited to less than or equal to 75 mRem) over 12consecutive months.



Supplemental Information (continued)

2. Allowable Concentrations


1) The dose rate due to radioactive materials released in gaseouseffluents from the site shall be limited to the following:

a) For noble gases: Less than or equal to 500 mRem/year tothe total body and less than or equal to 3000 mRem/yearto the skin, and

b) For all radioiodines and for all radioactive materialsin particulate form, and radionuclides, other than noblegases, with half-lives greater than eight days: Lessthan or equal to 1500 mRem/year to any organ via theinhalation pathway.

b. Liquid Effluents

1) The concentration of radioactive material released from thesite shall be limited to the concentrations specified in 10CFR Part 20, Appendix B, Table II, Column 2 for radionuclidesother than dissolved or entrained noble gases. For dissolvedor entrained noble gases, the concentration shall be limitedto the following:

Nuclide DWC (pci/ml)

3. Average Energy

a. Not Applicable.

4. Measurements and Approximations of Total Radioactivity


1) Containment Vent and Purge System is sampled by grab samplewhich is analyzed for principal gamma emitters and H-3.

2) Main Vent Stack is sampled by grab sample which is analyzedfor principal gamma emitters and H-3.

3) Standby Gas Treatment System is sampled by grab sample whichis analyzed for principal gamma emitters.




4) All release types as listed in 1 and 2 above, at the ventstack and as listed in 3 above, at the Standby Gas TreatmentSystem whenever there is a flow, are continuously sampled bycharcoal, particulate and composite samples which are analyzedfor iodines, principal gamma emitters, gross alpha, Sr-89 andSr-90. Noble gases, gross beta and gamma are continuouslymonitored by noble gas monitors for the vent stack and thestandby gas treatment system.

b. Liquid Effluents

1) Batch waste release tanks are sampled each batch for principalgamma emitters, 1-131, dissolved and entrained noble gases,H-3, gross alpha, Sr-89, Sr-90 and Fe-55.

2) Continuous releases are sampled continuously in proportion tothe rate of flow of the effluent stream and by grab sample.Samples are analyzed for principal gamma emitters, 1-131,dissolved and entrained noble gases, H-3, gross alpha, Sr-89,Sr-90 and Fe-55.
