DNPS 2008 Annual Radioactive Effluent Release Report DRESDEN NUCLEAR POWER STATION 2008 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT DOCKET NUMBERS: 50-010/50-237/50-249 EFFLUENT AND WASTE DISPOSAL

SUMMARY

ANNUAL REPORT, SUPPLEMENTAL INFORMATION Facility: Dresden Nuclear Power Station units I 1]2,3 Licensee: Exelon Niiclenr I, Regulatory Limits

a. Fission and activation gases:

Dose Rate I) Less than 500 mrem/year to the whole body.

2) Less than 3000 mrem/year to the skin.

Dose Gamma Radiation (each unit)

I) Less than or equal to 5 mrad/quarter.

2) Less than or equal to 10 mrad/year.

Beta Radiation (each unit)

I) Less than or equal to 10 mrad/quarter.

2) Less than or equal to 20 mrad/year.

b.,c. Iodine- 13 1, Iodine- 133, and all radionuclides in particulate form with half-lives greater than 8 days:

Dose Rate I) Less than 1500 mrem/year.

Dose (each unit)

I) Less than or equal to 7.5 mrem/quarter to any organ.

2) Less than or equal to 15 mrem/year to any organ.
d. Liquid effluents (each unit):
1) Less than or equal to 1.5 mrem to the whole body during any calendar quarter.
2) Less than or equal to 5 mrem to any organ during any calendar quarter.
3) Less than or equal to 3 mrem to the whole body during any calendar year.
4) Less than or equal to 10 mrem to any organ during any calendar year.
2. Maximum Permissible Concentration a., b., c. For fission and activation gases, iodines, and particulates with half-lives greater than 8 days, allowable dose rates are calculated by solving equations 2-3 and 2-4 of the Offsite Dose Calculation Manual (ODCM).
d. For liquid effluents, allowable release limits are calculated by solving equations 2-1 and 2-2 of the ODCM.
3. Average Energy Average energy is not used to determine dose to the public. The ODCM limits the dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem per year to the total body and less than or equal to 3,000 mrem per year to the skin. Compliance with these limits is demonstrated based on dose calculations using measured isotopic concentrations of effluent streams and not based on gross count rate measuring systems. Therefore, the average beta and gamma energies (E) for gaseous effluents as described in Regulatory Guide 1.21, "Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials- in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants," are not applicable.

4. Measurement and Approximations of Total Radioactivity
a. Fission and Activation Gases:
b. Iodines:
c. Particulates:

The Units 2/3 and Unit I Chimneys, Units 2/3 Reactor Building Vent, and Chemical Cleaning Building effluents are continually sampled for iodines and particulates. These samples are changed weekly and analyzed by gamma spectroscopy. The particulate filters are composited and sent to a vendor for gross alpha, Sr-89, Sr-90, and Fe-55 analysis. Noble gas grab samples of the Chimneys and Vent are obtained weekly and analyzed by gamma spectroscopy. Contributing streams of the Units 2/3 Chimney and 2/3 Reactor Building Vent are also sampled and analyzed by gamma spectroscopy. Tritium samples of the Chimneys and Vent are obtained monthly and analyzed by liquid scintillation.

For the Units 2/3 Chimney and Units 2/3 Reactor Building Vent effluents, the measured flow at the release points is used to calculate the curies released. For the Unit I Chimney and Chemical Cleaning Building effluents, the design basis flows are used to calculate curies released.

d. Liquid Effluents:

The river discharge tank is analyzed for gamma-emitting nuclides by gamma spectroscopy and for tritium by liquid scintillation prior to discharge. A representative portion of this sample is saved and composited with other discharges that occur during the calendar month. The composite is sent to a vendor for analyses of gross alpha, Sr-89, Sr-90, and Fe-55. The tank volumes and activities are used to calculate the diluted activity released at the discharge point from batch discharges.

Containment Cooling Service Water (CCSW) is sampled from the Low Pressure Coolant Injection (LPCI) heat exchangers monthly and analyzed for gamma-emitting nuclides by gamma spectroscopy. These samples are composited quarterly and analyzed for tritium, gross alpha, Sr-89, Sr-90, and Fe-55. Release volume is based on LPCI heat exchanger shell side volume.

e. Estimated Total Errors The estimated total errors were calculated as the square root of the sum of the squares of significant errors present in the sampling and analysis process.
f. Less than the Lower Limit of Detection (<LLD)

Samples are analyzed such that the ODCM LLD requirements are met. When a nuclide is not detected, then

<LLD is reported.

g. Estimation of Data/Corrections:

In May 2008, the 2/3 Main Chimney system flow rate meter was found to be indicating lower than actual flow rate due to plugging of the sensor probe. Review of historical 2/3 Main Chimney flow data indicates this condition began in April 2004. Per the ODCM, if 2/3 Main Chimney actual system flow rate is not available, the design flow rate of 1.25E+10 cc/min can be used. This flow rate is conservative because it is higher than the actual value. This flow rate was applied to 2/3 Main Chimney noble gas, particulate, iodine, and tritium measurements for the entirety of 2008. Units 2 and 3 gland seal and offgas effluent activity release calculations were not affected because they do not use the 2/3 Main Chimney flow rate meter.

b. I An access door on a 2/3 Chimney duct was found ajar on September 26, 2008. Investigation concluded the door was ajar for a maximum of 154 days and the maximum flow was 2000 scfm, and these maximum values were used for calculating the sample volume. Measurements of activity released from the 2/3 Chimney surrounding the event, consisting of tritium, Mn-54, Co-60, Sr-89, 1-131, 1-133, Xe-135, Cs-137, and Ba-140 were used to estimate the concentration of activity released. For this event, an estimated 6.1 0E-02 Ci of total activity was released to the environment as a ground-level gaseous release.
  • These releases are included in the Effluents Summation of all Releases Tables and in the Radiological Impact on Man.

7. Unmonitored Releases*
a. Liquid
1. Number of releases: 1
2. Total activity released: 8.17E-02 Ci
b. Gaseous
1. Number of releases: 8
2. Total activity released: 5.30E-04 Ci
a. I Water in on-site storm sewers is routinely sampled and analyzed for tritium content. The highest storm drain concentrations measured during each calendar quarter of 2008 was used to calculate the released activity for each quarter. The total activity released is based on an estimated typical discharge flow of 10 gallons per minute. An estimated 8.17E-02 Ci of tritium was released to the environment during 2008.
b. I The Unit I Main Turbine Floor is used as an area to work on contaminated equipment. The ventilation system is no longer operational and the floor is at ambient pressure with the outside environment. With radiological work activities being performed on the Unit I Main Turbine Floor, the potential exists for airborne activity to be released to the environment through various potential release points. Based on the work normally performed in this area, an estimated 3.60E-05 Ci of Cs- 137 was released from this area during 2008.

b.2 The Unit 2/3 Heating Steam system has low-level contamination present. During operation of the system, some steam is vented directly into the environment. Based on the activities detected in the system and the makeup volume used during the year, an estimated 1.11 E-06 Ci of Co-60 was released to the environment from this system during 2008.

b.3 The Chemistry Laboratory Ventilation system exhausts directly into the environment and is not monitored.

Based on an evaluation of activities performed in the area, the estimated activity released to the environment from the laboratory in 2008 is 1.22E-04 Ci of noble gases and 3.2 IE-06 Ci of iodines and particulates.

b.4 Past radiological surveys have identified low-level contamination in the East Turbine Building Ventilation ductwork. This system vents directly to the environment and is not monitored. Based on the highest activities detected during a survey of the system and the estimated area of the system surface, an estimated 2.OOE-06 Ci Co-60 and 1.49E-06 Ci Cs- 137 were released for a total estimated 3.49E-06 Ci of activity that was released to the environment from this system during 2008.

b.5 Four unmonitored releases occurred when the Unit 2 Isolation Condenser was actuated as part of planned surveillances on September 7, 10, 12, and 13, 2008. In the past, activity was detected on the shell side of the condenser / heat exchanger, which vents directly to the atmosphere. As a result, actuation of this system prompts analysis of the shell side contents and the downspouts from roofs under the exhaust. The highest concentrations of activity detected before, during, and after each actuation were used for release calculations, and release volume was calculated from changes in the shell-side level. An estimated 1.07E-06 Ci Co-60 and 3.63E-04 Ci tritium were released during these planned system actuations for a total estimated 3.65E-04 Ci of activity that was released to the environment from this system during 2008.

  • These releases are included in the Effluents Summation of all Releases Tables and in the Radiological Impact on Man.
8. Summary of Offsite Dose Calculation Manual (ODCM) Changes by Dresden Nuclear Power Station (DNPS) in 2008 Revision 7 of the ODCM was issued on October 15, 2008. The revision implements an existing contingency (i.e.,

expansion of the Restricted Area to accommodate the Steam Dryer Storage Building), clarifies existing guidance and data, makes typographical corrections, and makes editorial enhancements. Further description of the changes is provided in a separate attachment to this report.

C. CHANGES TO THE PROCESS CONTROL PROGRAM (PCP)

I. Revision 6 of RW-AA- 100, "Process Control Program for Radioactive Wastes" was issued on May 14, 2008. This revision clarified the definition of a High Integrity Container and clarified documentation requirements for High Integrity Container shipment to specific locations. These changes do not constitute a significant change to the PCP.

2. Revision 7 of RW-AA- 100, "Process Control Program for Radioactive Wastes" was issued on December 15, 2008.

This revision did not constitute a significant change to the PCP because it implemented administrative enhancements only. The enhancements implemented include the clarification of which section of 49CFR is applicable to burial site requirements, the addition of references, and corrected the use of "should," "shall," "may," and "will."

No major changes were made to the DNPS radioactive liquid, gaseous, or solid waste treatment systems in 2008.

DOCKET NUMBERS: 50-010/50-237/50-249 D. 40CFRI90 Compliance The General Electric Hitachi Nuclear Energy Morris Operation (GE-Hitachi Morris Operation) facility is physically located near Dresden Station and, in addition to evolutions performed at Dresden station, is considered in the evaluation of the uranium fuel cycle on members of the public in the general environment for 40CFR190 compliance.

Dresden decommissioning activities (Unit 1) and operations (Units 2 and 3) resulted in a maximum 1.32E-02 mrem organ dose and 9.19E+00 mrem Deep Dose Equivalent. Radiological Environmental Monitoring Program (REMP) direct radiation monitoring at or near the site boundary demonstrates that Deep Dose Equivalent calculations are conservative.

No effluents were released from the Dresden Independent Spent Fuel Storage Installations (ISFSIs) during 2008.

REMP direct radiation monitoring at or near the site boundary demonstrates that the ISFSIs do not result in measurable dose to the public.

Steam Dryers from Units 2 and 3 reactors were relocated from their respective reactor buildings to a storage location on site north of the units during August 2008. Dose at the Restricted Area Boundary (RAB) due to the dryer moves was measured with thermoluminescent dosimeters (TLDs) along the travel path at the RAB or inside the RAB. No measurable dose to the public due to the dryer moves was detected. TLDs placed in the vicinity of the Steam Dryer Storage Building inside the RAB measured 1.00E+00 mrem greater than background (background as measured at the REMP control location) during the period of August and September 2008. No dose greater than background was measured using the same methodology during the period of October through December 2008. No effluents were released during the dryer moves and the Steam Dryer Storage Building is sealed to prevent airborne effluents. In summary, dryer moves and storage resulted in 1.00E+00 mrem Deep Dose Equivalent and no organ dose in 2008.

Per the 2008 GE-Hitachi Morris Operation IOCFR72.44(d)(3) report, maximum dose at their site boundary from direct radiation exposure was 7. 1OE-01 mrem and maximum organ dose was 1.40E-02 mrem for 2008.

Maximum Deep Dose Equivalent from Dresden and GE-Hitachi Morris Operation activities is 9.90E+00 mrem during 2008, which is 3.96E+0I% of the 40CFR 190 limit of 2.50E+0I mrem.
