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.

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 Standby Gas Treatment System whenever there is flow, 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.
- b.
Liquid Effluents I)
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.
- 2)
Continuous releases are sampled continuously in proportion to the 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.

Effluent Monitoring Instrumentation timeclocks and sample anomalies.
Time clocks:
There were no effluent monitoring time clocks exceeded in 2004 Sample anomalies:
During refueling outage LIRIO, 1-131 was detected, at levels slightly above LLD, via analysis of the Waste Water Treatment Facility effluent composite sample. This anomalous sample result was entered into the Station Corrective Action Program as AR# 195907 and is discussed in this section, as this sample is not required by the ODCM program.
Rather, the WWTF sample is obtained and analyzed daily when the facility is in operation and serves as a trending tool. The Cooling Pond Blowdown to the Illinois River is monitored via composite sampling and serves as the means for determining dose to the public. Detection of activity at the WWTF prompts in-plant "clean sump" sampling to identify and correct the source. In this case the source of 1-131 activity were traced back to the Unit One fire sump, a "clean" sump. Efforts to identify inputs into the fire sump as a source were unsuccessful. A review of medical records was also inconclusive, as some records did not specify an isotope.
As a conservative measure a dose calculation was performed since the WWTF discharges to the LaSalle Cooling Lake. Utilizing the activity levels measured and the gallon throughput of the WWTF for the period, a total activity of 1.9 uCi's of 1-131 resulted in a calculated resultant maximum total body dose of 5.484 E-10 mRem (child) and Internal organ dose of 3.69E-10 mRem (infant thyroid). Again, this calculation was performed as a conservative measure. It should be noted that the LaSalle Cooling Lake does not serve as a drinking water supply and was closed to public access during the period in question (1/1 3/04 - 1/15/04). No positive activity was identified throughout the reporting period in ODCM required Pond Blowdown composite samples. LaSalle Cooling Lake REMP samples were reviewed following the occurrence and found to reveal no adverse affects.
