PNP was taken off line on June 24, 2010, to repair control rod drive mechanism leakage. The plant was returned to service on July 3, 2010. PNP was taken off line on October 3, 2010, for a refueling outage, and was returned to service on October 29, 2010. PNP remained on line for the remainder of 2010.A.

Supplemental Information

1. Abnormal Discharges In December 2007, tritium was detected in a groundwater monitoring well at a level of 22,000 pCi/L. The source of the activity is leakage associated with T-91, the utility water storage tank, and associated piping. T-91 is used to store processed liquid waste prior to discharge.

No radionuclides other than tritium have been detected in the groundwater.

Tritium is still being released to the environment (Lake Michigan) via an unmonitored pathway, as demonstrated by the continued detection of monitoring well sample activity.Page 1 of 6 However, repairs have been made and tritium concentrations have dropped to approximately 90% of values seen in previous years. A definitive release rate or total activity released cannot be determined.

Conservatively, 0.5% of the total tritium activity released via batch releases, or half of the percentage that was used in 2007, 2008, and 2009, was used for 2010 effluent calculations.

Date and Duration -Tritium was first detected in a monitoring well in December 2007 and release to the environment is still occurring.

Location -The location is between the northwest corner of the auxiliary building and Lake Michigan; the plume roughly paralleling piping associated with T-91.Volume -The volume release is conservatively estimated at 0.5% of liquid radioactive waste discharge volume -3886 gallons.Estimated Activity of Each Radionuclide

-3.37 curies of tritium Effluent Monitoring Results -PNP has no offsite monitoring wells as part of the ground water monitoring program.On-site Monitoring Results -Monitoring well sample results range in concentration from < MDA to 11,029 pCi/L for the most affected well.Depth to Local Water Table -The depth is approximately eight to nine feet.Classification of Subsurface Aquifers -Not used for drinking water.Size and Extent of Any Groundwater Plume -Fifteen yards wide by fifty yards long.Expected Movement/Mobility of Groundwater Plume -Westerly direction down-gradient toward Lake Michigan at approximately two feet per day.Land Use Characteristics

-PNP site property, water not used for drinking or irrigation.

Remedial Actions Considered or Taken -None Calculated Member of Public Dose Attributable to the Release -Total body and organ dose are both 2.65E-6 mrem.Calculated Member of Public Dose Attributable to the Discharge

-Total body and organ dose are both 2.65E-6 mrem.Page 2 of 6 Actions Taken to Prevent Recurrence

-T-91 has been repaired and recirculation piping from the auxiliary building to T-91 has been replaced.The T-90/T-91 overflow line is drained routinely.

NRC Notification, Date and contact Organization

-The NRC was notified on December 10, 2007, by PNP.2. Non-Routine Planned Discharges None.3. Radioactive Waste Treatment System Changes None.4. Annual Land Use Census Changes The garden critical receptor is now located in the southeast sector at 1.47 miles. The residence critical receptor is unchanged.

Also unchanged is that there are no beef cattle, dairy cows or goats located within five miles of the plant.5. Effluent Monitoring System Inoperability The effluent monitors that were out of service for greater than 30 days were: RIA-2323, B steam generator main steam line monitor, was out of service from March 28, 2010, to July 26, 2010 (120 days). RIA-2327, high range noble gas monitor, was out of service from July 4, 2010, to December 15, 2010 (142 days).6. Offsite Dose Calculation Manual (ODCM) Changes The ODCM was revised on July 7, 2010. Changes included:* Tables 1.3, "Palisades XOQDOQ," 1.4, "Land Use Census," and Table 1.4a, "Critical Receptors," were removed and placed in a site procedure.

-Removed Section C, "Design--Basis Quantities Limits" and all references to Design Basis Quantities (DBQ).* Removed Section I D, Optional Quarterly Dose Calculations.

  • Editorial changes.ODCM, Appendix A Changes:* Removed asterisk from the Mo-99 isotope that permitted a higher lower limit of detection (LLD) from Tables B-1 and D-1.Page 3 of 6
  • Removed the phrase "Xe-133 content" and replaced it with "dose consequences" from Section III E 2 a.* On Table E-3, Lower Limit of Detection, Listed Ba-140 and La-140 in two separate lines and changed the LLD value for Ba-140 from 15 pCi/I to 60 pCi/l. Also listed Zr-95 and Nb-95 on two separate lines and changed the LLD for Zr-95 from 15 pCi/L to 30 pCi/I.* Removed the majority of Section IV A, that described what was to be included in the Annual Radioactive Effluent Release Report, and instead stated that the contents and format should follow the guidance of Regulatory Guide 1.21, Measuring, Evaluating, and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste.* Added a new section,Section VI, Onsite Ground Water Monitoring.

This section provides a brief description of the ground water monitoring wells added in 2007 and 2008.* Editorial changes.Enclosure 1 contains the ODCM, Revision 24, per the requirements of Technical Specification 5.5.1 .c.3.7. Process Control Program Changes None.8. Errata/Corrections to Previous Reports None 9. Other Groundwater Monitorinq PNP installed five groundwater monitoring wells in 2007, and added an additional nine wells in 2008. These wells were strategically placed within the owner controlled area, both inside and outside the protected area to allow detection of radioactive contamination of ground water due to leaks or spills from plant systems. Monitoring well (MW) 3 is most indicative of the leak described in the Abnormal Leaks section. Tritium levels ranged from a less than minimum detectable activity (MDA) to 11,029 pCi/L. Monitoring wells MW2 and MW1 1 tritium levels ranged from <MDA to 2944 and 1217 pCi/L, respectively.

The remaining wells showed no activity throughout the year. Well locations are depicted in Figure 1.Page 4 of 6 Carbon-14 In 2010, PNP and other facilities participated in an EPRI task force to build a model to accurately estimate gaseous C-14 releases, given some key site-specific plant parameters (mass of the primary coolant, average thermal neutron cross section, rated MW, etc). This work was completed in November 2010. The estimates for C-14 were constructed using the aforementioned EPRI methodology contained with EPRI 1021106, Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents.

Using the C-14 curie estimates, the annual dose to man was derived from guidance contained within Regulatory Guide 1.109. Because the dose contribution of C-14 from liquid radioactive waste is much less than that contributed by gaseous radioactive waste, evaluation of C-14 in liquid radioactive waste is not required. (Reg Guide 1.21 Rev 2)Annual C-14 release PNP and subsequent doses Total Gaseous C-14 Released Curies = 7.69 Gaseous C-14 as C02 Curies = 2.31 Effective Child TB Dose, C-14 mrem = 0.0207 Effective Child Bone Dose, C-14 mrem = 0.104 The quarterly curies released are provided in Tables A-1 A and A-1 B.Airborne doses due to C-14 are grouped under the category of Particulate, Iodine, and Tritium which are contained in Table A-4.Page 5 of 6 FOGUE I1 GRUND'MWATER MOTORDM WE~LL LOCATIONS OR> P~c TF-TRAkGE ~//mW10-O&8'9)P~iMaRY , MMGAWI///-, A MMA-08 ------LEGEND FENCELINE SHEET PE AIING WALL APPROXIMATE SHORELINE MONITORING WELL LOCATION SOIL BORING LOCATION figure 4.1 GROUNDWATER MONITORING WELL LOCATIONS PALISADES NUCLEAR POWER PLANT 27780 BLUE STAR HWY.Covert, Michigan UOIlSit$UCIUUL?31*UCUUOILJV I
