Supplemental Information
Regulatory Limits
a. Gascous Effluents

2) The dose to an individual from radioiodines and radioactive materials in particulate form, andradionuclides, other than noble gases, with half-lives greater than eight days in gaseous effluentsreleased, from each reactor unit, from the site shall be limited to the following:
3)a) During any calendar quarter: Less than or equal to 7.5 mRems 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 radioactive materials in liquid effluentsreleased, from each reactor unit, from the site shall be limited:
a) During any calendar quarter: Less than or equal to 1.5 mRem to the total body and to lessthan 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 thanor 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 andradiation, from uranium fuel cycle sources shall be limited to less than or equal to 25 mRern to thebody or any organ (except the thyroid, which shall be limited to less than or equal to 75 mRem)over 12 consecutive months.

Supplemental Information (continued)
2. Allowable Concentrations -
a. Gaseous Effluents
I) The dose rate due to radioactive materials released in gaseous effluents from the site shall belimited to the following:
a) For noble gases: Less than or equal to 500 mRem/year to the total body and less than orequal to 3000 mRem/year to the skin, and
b) For all radioiodines and for all radioactive materials in particulate form, andradionuclides, other than noble gases, with half-lives greater than eight days: Less than orequal to 1500 mRem/year to any organ via the inhalation pathway.
b. Liquid Effluents
1) The concentration of radioactive material released from the site shall be limited to ten (10) timesthe concentrations specified in 10 CFR Part 20, Appendix B, Table 11, Column 2 for radio iuclidesother than dissolved or .entrained noble gases. For dissolved or entrained noble gases, theconcentration shall be limited to the following:
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 Principalgamma emitters and H-3.
2) Main Vent Stack is sampled by grab sample, which is analyzed for principal gamma emitters andH-3.
3) Standby Gas Treatment System is sampled by grab sample, which is analyzed for principal gammaemitters.

Supplemental Information (continued)
4) All release types as listed in I and 2 above, at the vent stack and as listed in 3 above, at the StandbyGas Treatment System wvhenever there is flow, are continuously sampled by charcoal cartridge andparticulate filter paper, which are analyzed for iodines and principal gamma emitters. Particulatefilter papers are composited and analyzed for gross alpha, Sr-89 and Sr-90. Noble gases, gross betaand gamma are continuously monitored by noble gas monitors for the vent stack and the standbygas treatment system.
b. Liquid Effluents
1) Batch waste release tanks are sampled each batch for principal gamma emitters, 1-131, dissolvedand entrained noble gases, H-3, gross alpha, Sr-89, Sr-90 and Fe-55.
2) Continuous releases are sampled continuously in proportion to the rate of flow of the effluentstream and by grab sample. Samples are analyzed for principal gamma emitters, 1-131, dissolvedand entrained noble gases, H-3, gross alpha, Sr-89, Sr-90 and Fe-55.

6. Abnormal Releases
a. Gaseous
1) Number of releases: None
2) Total activity released: N/A
b. Liquid
1) Number of releases: None
2) Total activity released: N/A
7. Process Control Program
The: c were no changes to the Process Control Program during this time period.
8. Effluent Monitoring Instrumentation timeclocks and sample anomalies.
Time clocks:
There were no effluent monitoring time clocks exceeded in 2005
Sirnple anomalies:
There were no sampling anomalies experienced during 2005
9. Offsite Dose Calculation Manual Revisions.
Two revisions were made to the LaSalle ODCM during the reporting period. Revision 8 replaced a 72 hrshutdown timeclock associated with inoperable pre-treat rad monitors with compensatory sampling requirements.The second revision of 2005 standardized the ODCM under ITS format JAW Exelon Corporate Procedures.Through this process LaSalle's ODCM became CY-LA-170-301 Rev. 0. The most recent revision of LaSalle'sODC'M is included as Appendix A.
