Quad Cities Nuclear Power Station 2018 Annual Radioactive Effluent Release Report Effluent and Waste Disposable Summary Supplemental Information Discussion of Radiation and Radioactivity <1>

Radiation and Radioactivity All matter is made of atoms. An atom is the smallest part into which matter can be broken down and still maintain all its chemical properties. Nuclear radiation is energy, in the form of waves or particles that is given off by unstable, radioactive atoms. Radioactive material exists naturally and has always been a part of our environment. The earth's crust, for example, contains radioactive uranium, radium, thorium, and potassium.

Some radioactivity is a result of nuclear weapons testing. Examples of radioactive fallout that is normally present in environmental samples are Cesium-137 and Strontium-90. Some examples of radioactive materials released from a nuclear power plant are Cesium-137, lodine-131, Strontium-90, and Cobalt-GO. Radiation dose is measured in units of millirem; much like temperature is measured in degrees. A millirem is a measure of the biological effect of the energy deposited in tissue. The natural and man-made radiation dose received in one year by the average American is 300 to 400 mrem (References 2, 3, 4 in Table - 1 below). Radioactivity is measured in curies. A curie is that amount of radioactive material needed to produce 37,000,000,000 nuclear disintegrations per second.

Sources of Radiation mentioned previously, naturally occurring radioactivity has always been a part of our environment. Table - 1 ows the sources and doses of radiation from natural and man-made sources.

Quad Cities Nuclear Power Station 2018 Annual Radioactive Effluent Release Report Effluent and Waste Disposable Summary Supplemental Information Cosmic radiation from the sun and outer space penetrates the earth's atmosphere and continuously interacts with us via rays and charged particles. Some of this cosmic radiation interacts with gases and particles in the atmosphere, making them radioactive in turn. These radioactive byproducts from cosmic ray interaction are referred to as cosmogenic radionuclides. Isotopes such as Beryllium-7 and Carbon-14 are formed in this way.

Exposure to cosmic and cosmogenic sources of radioactivity results in about 33 mrem of radiation does per year.

Additionally, natural radioactivity is in our body and in the food we eat (about 29 mrem/year), the ground we walk on (about 21 mrem/year) and the air we breathe (about 228 mrem/year). The majority of a person's annual dose results from exposure to radon and thoron in the air we breathe. These gases and their radioactive decay products arise from the decay of naturally occurring uranium, thoron and radium in the soil and building products such as brick, stone, and concrete. Radon and thoron levels vary greatly with location, primarily due to changes in the concentration of uranium and thorium in the soil. Residents at some locations in Colorado, New York, Pennsylvania, and New Jersey have a higher annual dose as a result of higher levels of radon/thoron gases in these areas. In total, these various sources of naturally-occurring radiation and radioactivity contribute to a total does of about 311 mrem per year.

In addition to natural radiation, we are normally exposed to radiation from a number of man-made sources. The single largest doses from man-made sources result from the therapeutic and diagnostic applications of x-rays and radiopharmaceuticals. The annual dose to an individual in the U.S. from medical and dental exposure is bout 300 mrem. Consumer products, such as televisions and smoke detectors, contribute about 13 mrem/year.

uch smaller does result from weapons fallout (less than 1 mrem/year) and nuclear power plants. Typically, the verage person in the United States receives about 314 mrem per year from man-made sources.

2. Maximum Permissible Concentration a,b,c. For Fission and activation gases, iodine and particulates with half-lives greater than 8 days, allowable release limits are calculated by solving equations 2.0-5 and 2.0-6 from the Offsite Dose Calculation Manual Part II Chapter 2. The alarm setpoints is conservatively set at approximately 10% of the 10CFR20 limit.
d. For liquid effluents, with the exception of tritium and dissolved and entrained noble gases, allowable release limits are calculated by solving equations 2.0-1 and 2.0-2 from the Offsite Does Calculation Manual Part II Chapter 2. The MPC values used for the monitors were as follows:

Radwaste discharge 5.00E-06 µCi/ml Service water 1.00E-05 µCi/ml The allowable release limits for tritium and dissolved and entrained noble gases are as follows:

Tritium: 3.00E-03 µCi/ml taken from Reg Guide 1.21 Dissolved and Entrained Noble Gases: 2.00E-04 µCi/ml taken from NU REG 1302

3. Average Energy The average gamma energy used to calculate the alarm setpoints for the noble gas monitors are as follows:

9.21E-01 MeV for Quarter 1 9.71E-01 MeV for Quarter 2 9.43E-01 MeV for Quarter 3 9.60E-01 MeV for Quarter 4

4. Measurements for Approximations of Total Radioactivity
a. Fission and Activation Gases
b. Iodines
c. Particulates a,b,c. The main chimney and reactor building ventilation exhaust systems are continually monitored for iodines and particulates. These samples are pulled every 7 days and analyzed by gamma isotopic. The particulate papers are composited every 31 days and sent to a vendor for Sr-89/90 and gross alpha analysis. Noble gas grab samples are pulled and analyzed by gamma isotopic weekly. Tritium samples are pulled and analyzed every month.

The Sr-89/90, Fe-55, Ni-63 and gross alpha curies released values reported are actual. On a real time basis, the portion of the "percent of applicable limit" for these contributors is reported based on projections using the previous available data. The actual results are Page 14of78

Quad Cities Nuclear Power Station 2018 Annual Radioactive Effluent Release Report Effluent and Waste Disposable Summary Supplemental Information obtained by editing the ODCM software inputs when the vendor results become available.

Therefore, the "percent of applicable limits" in this report are actual.

The continuous chart recorders for the monitors on the release points are reviewed for spikes and the activity released is calculated. An additional calculated activity for noble gases is added to the main chimney or reactor building release each month if applicable. This calculation is done because most of the grab samples show less than the lower limit of detection due to the low amount of activity and the large dilution flow at the sample point. The calculation takes into account the normal offgas train and the gland steam contribution to the release.

The average flow at the release points is used to calculate the curies released.

There are no ground level releases from QCNPS. All monitored releases are considered either elevated or mixed mode.

d. Carbon-14 Quad Cities has estimat,ed its Carbon-14 generation and release in accordance with EPRI Technical Report 1021106, "Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents".

The Quad Cities estimate of 2.84E+Ol Ci of Carbon-14 and the resultant 2.84E+Ol Ci 14C02 released is based upon a normalized Carbon-14 production rate of 5.lOE+OO Ci/GWTh-yr, a gaseous release fraction of 1.00, a Carbon-14 C02 fraction of 1.00, a reactor power rating of 2957 MWTh/unit for 2 units, and a calculated Effective Full Power days based upon Total Core Therms data. The maximum expected annual dose contribution from Carbon -14 has been calculated to be 2.08E-01 mrem/year organ dose and 4.15E-02 mrem/year total body dose. This was obtained using maximum gross thermal capacity maintained for 365 days for both units.

e. Liquid Effluents River Discharge Tanks, when performed, are analyzed prior to discharge by gamma isotopic. A composite representative portion of this sample is saved. This is composited with other discharges that occurred every 31 days and is analyzed for tritium and gross alpha. The monthly composites are composited quarterly and sent to a vendor for Sr-89/90, Fe-55, and Ni-63 analyses. The discharge bay is sampled every 31 days and analyzed for gamma by isotopic, for tritium and for gross alpha. It is sampled quarterly and sent to a vendor for Sr-89/90, Fe-55, and Ni-63 analysis. On a real time basis, the portion of the "percent of applicable limit" for these contributors is based on projections using scaling factors.

The actual results are obtained by editing the ODCM software inputs when the vendor results become available. Therefore, the "percent of applicable limits" in this report are actual. The tank volumes and activities are used to calculate the curies released for the River Discharge Tank. The total water released during the quarter and the activity is used to calculate the diluted activity released at the discharge bay, from batch discharges.

6. Abnormal Releases
a. Liquid On March 28, 2018, approximately three to four feet of water was observed in a Radwaste Piping Vault, located adjacent to monitoring well QC-GP-18. Samples were collected from the water in the vault as well as the groundwater in QC-GP-18. Both samples had tritium concentration of approximately 4.S million pCi/L. Approximately S,000 gallons of water was pumped from the vault and processed through the Station's Radwaste System on March 28, 2018. Remediation of the groundwater near the RW Pipe Vault began on March 29, 2018 via pumping from monitoring well QC-GP-18 and processing through the Stations Radwaste System.

On March 29, 2018, the station contacted the Illinois Environmental Protection Agency (IEPA) and Illinois Emergency Management Agency (IEMA) to report a release of a radionuclide pursuant to 3S Ill. Adm. Code 1010.202. The station also notified the Nuclear Regulatory Commission (NRC) of these report to state agencies to satisfy 10CFRS0.72(b)(2)(xi), notification of the NRC for any event related to the health and safety of the public for which a notification to other government agencies has been or will be made (EN #S3299)

The cause of the tritium activity in the vault and QC-GP-18 was determined to be a leaking pipe clamp located within the RW Pipe Vault and degraded seams in the concrete vault which allowed water to seep from the vault into the surrounding groundwater. The pipe clamp was repaired and the concrete/degrade seams in the vault sealed.

On April 2, 2018, an extraction well (RW-1) was installed nearthe vault and QC-GP-18 to assist in remediating the tritium activity in groundwater. The extraction well began pumping groundwater on April 10, 2018 for processing through the Station's Radwaste System. On May 2, 2018 effluent from RW-1 was routed to the Discharge bay for release. On May 7, 2018 effluent from QC-GP-18 was routed to the Discharge Bay for release. On November 24, 2018, both well remediation pumps were shut down for the winter season. Between March 29, 2018, and November 24, 2018, approximately 1.8 million gallons of groundwater was pumped from the vicinity of the RW Pipe Vault for remediation purposes. Prior to the RW Pipe Vault release in March 2018, QC-GP-18 groundwater tritium concentration was 22,300 pCi/L. When remediation ceased on November 24, 2018, QC-GP-18 tritium concentration was 27,600 pCi/L.

During the period of May 2nd 2018 to Nov 24th 2018 and May 7th to Nov 24th 2018 respectively, wells RW-1 and QC-GP-18 were routed to send the groundwater affected by the spill to the Discharge Bay, which is Quad Cities' liquid effluent final release point.

Upon initiation of routing to the discharge bay, samples were collected from each well on a daily basis to monitor for tritium concentration, gamma spectroscopy, and to create monthly composite samples to be analyzed for gross alpha, Fe-SS, Ni-63, Sr-89, and Sr-90. LLDs and sampling requirements for this monitored abnormal release are Page 17 of 78

Quad Cities Nuclear Power Station 2018 Annual Radioactive Effluent Release Report Effluent and Waste Disposable Summary Supplemental Information identical to the requirements listed in the ODCM for routine liquid effluent analysis. Starting the week of June 19th, 2018, due to consistently decreasing concentrations of tritium identified in the samples, sample collection was changed to a frequency of once per week. No other changes were made to the previously identified sampling and analysis frequency.

Samples were also obtained at the Discharge Bay outfall and analyzed for the same radionuclides and at the same frequency as the well samples. No samples of the discharge bay outfall showed detectable activity.

During the period that the wells were routed to the discharge bay, only tritium was detected in the well discharge at levels above the required limit of detection. A total of 3.53E-01 Ci of tritium were released to the Mississippi River via this abnormal release. This amounts to 4.31%

of the total liquid tritium released from Quad Cities Station in 2018. The associated dose impact to members of the public from this abnormal release was calculated to be 3.17E-08 mRem to the Teen/Liver dose pathway, which is 7 .08E-04% of the total liquid dose to this maximally exposed individual. The total body dose associated with this abnormal release was calculated to be 2.0lE-07 mRem to the Adult Total Body, which is 7.13E-03% of the total liquid dose to this maximally exposed individual. The associated curies and doses due to this release are included in the Summation of All Releases Table (page 6 of this report), Mississippi River Continuous Mode (page 7 of this report) and Radiological Impact on Man (page 18 of this report).
