1.0 Introduction

This Radioactive Effluent Release Report, for Comanche Peak Nuclear Power Plant Unit 1 and Unit 2, is submitted as required by Technical Specification 5.6.3 and Offsite Dose Calculation Manual (ODCM) Administrative Control 6.9.1.4 for the period January 1, 2008, through December 31, 2008.1.1 Executive Summary The radioactive effluent monitoring program for the year 2008 was conducted as described in the following report. The results of the monitoring program indicate' the continued effort to maintain the release of radioactive effluents to the environment as low as reasonably achievable (ALARA).Gaseous Effluents:

'from the spent fuel pools. Factors contributing to the tritium activity in the pools is related to the type of fuel used (i.e., 18-month fuel) the core life and power output and number of core cycles.2 The majority of the gaseous activity and 100% of the Iodine activity was released in the first 2 quarters of the year as a result of 2RF10 with fuel defects.3 No alpha activity was released.4 Whole body dose was still very low (0.29% of Technical Specification).

Overall the gaseous radioactivity releases from CPNPP are well controlled and maintained ALARA.CPNPP is well below all applicable limits for gaseous releases.Page 5 of 44 Liquid Effluents:

A summary of all the radioactive liquid releases to the environment during 2008: Liquid Waste 2008 2007 Comments Total Activity (excluding tritium) 15.2 mCi 7.6 mCi 1 Tritium Activity 2426 Ci 532 Ci 2,3 Total Whole Body Dose 0.127 mRem 0.137 mRem n/a Comments/.1 CPNPP had 2 refueling outages during 2008. Despite the fuel defects on Unit 2 at 2RF10, the site managed to limit the total activity (excluding tritium) to 15 mCi.2 A combination of factors resulted in the large increase of tritium released during 2008 as described in Note 3. During 2007, an unusually low amount of tritium was released.

Averaging the tritium from 2007 and 2008 results in a more "normal" value of 1479 Ci.3 In preparation for 2RF10, 22 PET tanks were processed during the first quarter of 2008. Much of this waste water was due to U2 end of cycle dilutions and contained higher concentrations of tritium. Unit 1 tritium concentrations were at the highest level for the cycle. Lastly, with the use of IFBA (Integral Fuel Burnable Absorber) fuel, additional tritiated waste water was produced from initial borations and subsequent dilutions.

The combination of all of these factors resulted in a much larger than usual total tritium release for 2008.Meteorological Data The CPNPP meteorological system achieved a 98.0% recoverable data rate for the joint frequency parameters required by Regulatory Guide 1.23 for wind speed, wind direction and delta temperature.

Monitors OOS > 30 Days During 2008 there were no Technical Specification/ODCM effluent radiation monitors out of service for >30 days.ODCM Changes There was one revision to the ODCM in 2008.Revis'ion 28 (9/11/08):

LDCR-OD-2007-1 (EVAL-2006-003080-05) (JDS) -Revised the definition of rated thermal power to reflect a 4.5% increase on Units 1 and 2 as issued by the. NRC in Amendment 146 to the Operating Licenses and Technical Specifications.

The large. volume in 2007 was from the steam generator replacement outage.2 The majority of the activity came from resins and filters.Overall, the radioactive effluent monitoring program has been conducted in an appropriate manner to ensure the activity released and associated dose to the public has been maintained as low as reasonably achievable (ALARA).Groundwater Tritium A positive indication (2186 pCi/L) for tritium was found in the artesian basin near the water plant.The source of the tritium was determined to be from the Squaw Creek Lake (approximate tritium concentration of 11,000 pCi/L). The basin discharges back to the lake. This concentration was well below the state reportable criteria of 20,000 pCi/L. This issue is tracked in our corrective action program.A positive indication (8380 pCi/L) for tritium was also found in Waste Monitoring Basin C liner leachate.

This water is contained within the double liner system of basin C; therefore, this incident does not confirm a leak from Basin C, but does suggest a leak in the primary liner of Basin C. Plans have been made to inspect and repair all basin liners. This issue is also tracked in our corrective action program.See section 6.10 for the details.Page 7 of 44

A value of 2.OE-04 ptCi/ml is used as the ECL for dissolved and entrained noble gases in liquid effluents.

2.3 Measurements

and Approximations of Total Radioactivity Measurements of total radioactivity in liquid and gaseous radioactive effluents were accomplished in accordance with the sampling and analysis requirements of Tables 4.11-1 and 4.11-2, respectively, of the CPNPP ODCM.Page 14 of 44

2.3.1 Liquid

Radioactive Effluents Each batch release was sampled and analyzed for gamma emitting radionuclides using gamma spectroscopy, prior to release. Composite samples were analyzed monthly and quarterly for the Primary Effluent Tanks (PET), Waste Monitor Tanks (WMT), Laundry Holdup and Monitor Tanks (LHMT) and Waste Water Holdup Tanks (WWHT). Composite samples were analyzed monthly for tritium and gross alpha radioactivity in the onsite laboratory using liquid scintillation, and gas flow proportional counting techniques, respectively.

Composite samples were analyzed quarterly for Sr-89, Sr-90 and Fe-55 by a contract laboratory.

The, results of the composite analyses from the previous month or quarter were used to estimate the quantities of these radionuclides in liquid effluents during the current month or quarter. The total radioactivity in liquid effluent releases was determined from the measured and estimated concentrations of each radionuclide present and the total volume of the effluent released during periods of discharge.

For batch releases of powdex resin to the LVW pond, samples were analyzed for gamma emitting radionuclides, using gamma spectroscopy techniques, prior to release. Composite samples were analyzed quarterly, for Sr-89 and Sr-90, by a contract laboratory.

For continuous releases to the Circulating Water Discharge from the LVW pond, daily grab samples were obtained over the period of pond discharge.

These samples were composited and analyzed for gamma emitting radionuclides, using gamma spectroscopy techniques..

Composite samples were also analyzed for tritium and gross alpha radioactivity using liquid scintillation and gas flow proportional counting techniques, respectively.

Composite samples were analyzed quarterly for Sr-89, Sr-90 and Fe-55 by a contract laboratory.

2.3.2 Gaseous

Radioactive Effluents Each gaseous batch release was sampled and analyzed for radioactivity prior to release. For releases from Waste Gas Decay Tanks, noble gas grab samples were analyzed for gamma emitting radionuclides using gamma spectroscopy.

For releases from the Containment Building, samples were taken using charcoal and particulate filters, in addition to noble gas and tritium grab samples, and analyzed for gamma emitting radionuclides prior to each release. The results of the analyses and the total volume of effluent released were used to determine the total amount of radioactivity released in the batch mode.For continuous effluent release pathways, noble gas and tritium grab samples were collected and analyzed 'Weekly for gamma emitting radionuclides by gamma spectroscopy and liquid scintillation counting techniques, respectively.

Continuous release pathways were continuously sampled using radioiodine adsorbers and particulate filters. The radioiodine adsorbers and particulate filters were analyzed weekly for 1-131 and gamma emitting radionuclides using gamma spectroscopy.

Results of the noble gas and tritium grab samples, radioiodine adsorber and particulate filter analyses from the current week and the average effluent flow rate for the previous week were used to determine the total amount of radioactivity released in the continuous mode.Monthly composites of particulate filters were analyzed for gross alpha activity, in the onsite laboratory using the gas flow proportional counting technique.

Quarterly composites of particulate filters were analyzed for Sr-89 and Sr-90 by a contract laboratory.

2.4 Batch

Releases A summary of information for gaseous and liquid batch releases is included in Table 7.1.2.5 Abnormal or Unplanned Releases Abnormal releases are defined as the unintended discharge of a volume of liquid or airborne radioactivity to the environment.

No abnormal or unplanned liquid or gaseous effluent releases occurred during 2008. Table 7.2 summarizes the abnormal and unplanned releases.3.0 GASEOUS EFFLUENTS The quantities of radioactive material released in gaseous effluents are summarized in Tables 7.3 and 7.4. All releases of radioactive material in gaseous form are considered to be ground level releases.4.0 LIQUID EFFLUENTS The quantities of radioactive material released in liquid effluents are summarized in Tables 7.5 and 7.6.5.0 SOLID WASTES The quantities of radioactive material released as solid effluents are summarized in Table 7.10.6.0 RELATED INFORMATION

6.1 Operability

of Liquid and Gaseous Monitoring Instrumentation ODCM Radiological Effluent Controls 3.3.3.4 and 3.3.3.5 require an explanation of why designated inoperable liquid and gaseous monitoring instrumentation was not restored to operable status within thirty days.During the period covered by this report, there were no instances where these instruments were inoperable for more than thirty days.6.2 Changes to the Offsite Dose Calculation Manual During the period covered by this report, there was one revision to the ODCM approved and/or implemented.

The revision number is 28. A complete copy of the ODCM, with change bars, will be provided as a separate Enclosure to the letter transmitting this report. The change revised the definition of rated thermal power to reflect a 4.5% increase on Units 1 and 2 as issued by the NRC in Amendment 146 to the Operating Licenses and Technical Specifications.

6.3 New Locations for Dose Calculations or Environmental Monitoring!

ODCM Administrative Control 6.9.1.4 requires any new locations for dose calculations and/or environmental monitoring, identified by the Land Use Census, to be included in the Radioactive Page 16 of 44 Effluent Release Report. Based on the 2008 Land Use Census, no new receptor locations were identified which resulted in changes requiring a revision in current environmental sample locations.

Values for the current nearest resident, milk animal, garden, X/Q and D/Q values in all sectors surrounding CPNPP were included in the 2008 Land Use Census.6.4 Liquid Holdup and Gas Storage Tanks ODCM Administrative Control 6.9.1.4 requires a description of the events leading to liquid holdup or gas storage tanks exceeding the limits required to be established by Technical Specification 5.5.12. Technical Requirements Manual 13.10.33 limits the quantity of radioactive material contained in each unprotected outdoor tank to less than or equal to ten curies, excluding tritium and dissolved or entrained noble gases. Technical Requirements Manual 13.10.32 limits the quantity of radioactive material contained in each gas storage tank to less than or equal to 200,000 curies of noble gases (considered as Xe-133 equivalent).

These limits were not exceeded during the period covered by this report.6.5 Noncompliance with Radiological Effluent Control Requirements This section provides a listing and description of Abnormal Releases, issues that did not comply with the applicable requirements of the Radiological Effluents Controls given in Part I of the CPNPP ODCM and/or issues that did not comply with associated Administrative Controls and that failed to meet CPNPP expectations regarding Station Radioactive Effluent Controls.

Detailed documentation concerning evaluations of these events and corrective actions is maintained onsite.6.5.1 Normal, Unplanned Gaseous Release No normal, unplanned gaseous effluent releases occurred during 2008.6.5.2 Abnormal, Unplanned Gaseous Effluent Release No abnormal, unplanned gaseous effluent releases occurred during 2008.6.5.3 Abnormal.

Unplanned Liquid Effluent Releases No abnormal, unplanned liquid effluent releases occurred during 2008.6.6 Resin Releases to the LVW Pond A total of 277 ft 3 of powdex resin was transferred to the LVW pond during the period covered by this report. The cumulative activity deposited in the LVW pond since operations began through the end of 2008 is 1.16E-03 Curies, consisting of Co-58, Co-60, Cs-134, Cs-137, 1-131 and Sb-125.6.7 Chan2es to the Liquid. Gaseous, and Solid Waste Treatment Systems In accordance with the CPNPP Process Control Program, Section 6.2.6.2, changes to the Radwaste Treatment Systems (liquid, gaseous and solid) should be summarized and reported to the Commission in the Radioactive Effluent Release Report if the changes implemented required a Page 17 of 44 10CFR50.59 safety evaluation.

For the reporting period of this report, no changes to the Radwaste Treatment Systems occurred that meet the reporting criteria of the Process Control Program.6.8 Meteorological Monitoring Program In accordance with ODCM Administrative Control 6.9.1.4, a summary of hourly meteorological data, collected during 2008, is retained onsite. This data is available for review by the NRC upon request. Joint Frequency Tables are included in Attachment

8.1. During

2008, the goal of >90%joint data recovery was met.6.9 Assessment of Doses 6.9.1 Doses Due to Liquid Effluents The doses to an adult from the fish and cow-meat consumption pathways from Squaw Creek Reservoir were calculated in accordance with the methodology and parameters in the ODCM. The results of the calculations are summarized on a quarterly and annual basis in table 7.7.6.9.2 Doses Due to Gaseous Effluents The air dose due to gamma emissions and the air dose due to beta emissions were calculated using the highest annual average atmospheric dispersion factor at the Site Boundary location, in accordance with the methodology and parameters in the ODCM. The results of the calculations are summarized on a quarterly and annual basis in Table 7.8.6.9.3 Dose Due to Radioiodines, Tritium and Particulates The doses to an adult, teen, child, and infant from radioiodines and particulates, for the pathways listed in Part II, Table 2.4 of the ODCM, were calculated using the highest dispersion and deposition factors, as appropriate, in accordance with the methodology and parameters in the ODCM. The results of the calculations are summarized on a quarterly and annual basis in Table 7.9.6.9.4 40CFR190 Dose Evaluation ODCM Radiological Effluent Control 3.11.4 requires dose evaluations to demonstrate compliance with 40 CFR Part 190 only if the calculated quarterly or yearly doses exceed two times the applicable quarterly or annual dose limits. At no time during 2008 were any of these limits exceeded, therefore no evaluations are required.6.9.5 Doses to a MEMBER OF THE PUBLIC From Activities Inside the Site Boundary Three activities are considered in this evaluation:

fishing on Squaw Creek Reservoir, recreation activities at the CPNPP employee recreational area and site tours through the CPNPP Visitors Center.The highest dose occurred in the evaluation for fishing, resulting in a dose of 1.27E-4 mrem/yr.The dose to a MEMBER OF THE PUBLIC (fisherman) on Squaw Creek Reservoir was calculated Page 18 of 44 based on fishing twice a week, five hours each day, six months per year. Pathways included in the calculation were gaseous inhalation and submersion.

Liquid pathways are not considered since all doses are calculated at the point of circwater discharge into the lake.The dose to a MEMBER OF THE PUBLIC engaged in recreational activities at the CPNPP employee recreational park was calculated based on one visit a week, five hours each day, six months per year. Pathways included in the calculation were gaseous inhalation, submersion and ground plane.The dose to a MEMBER OF THE PUBLIC during site tours through the CPNPP Visitors Center was calculated based on two visits per year, thirty minutes each visit. Pathways included in the calculation were gaseous inhalation and submersion.

Due to increased security, routine fishing on Squaw Creek Reservoir and visitation by the public on-site has been significantly restricted.

The calculations are still valid and included in the event security access restrictions are ever returned to previous conditions and controls.All calculations were performed in accordance with the methodology and parameters in the ODCM.6.10 Groundwater Tritium monitoring Program Samples of perched groundwater are taken quarterly in accordance with the site groundwater tritium monitoring program. During the first quarter of 2008, a sample from the Water Production Plant artesian basin (storm drain) had a positive value for tritium of 2.18E-6 uCi/cc (2186. pCi/L).This value was well below state reportable limit of 20,000 pCi/L. The source of the tritium was from Squaw Creek Lake water (tritium concentration approximately 11,000 pCi/L) from a small leak in the water treatment system. Subsequent samples were taken to monitor for degrading conditions.

Since this basin is part of the groundwater tritium monitoring program, the event was put into the corrective action program for tracking.

The basin discharges back to Squaw Creek Lake.Analysis of the fourth quarter ground monitoring conducted on 11/06/08 also indicated the presence of tritium in Waste Monitoring Basin C liner leachate at a concentration of 8380 pCi/L.This water is contained within the double liner system of basin C; therefore, this incident does not confirm a leak from Basin C, but does suggest a leak in the primary liner of Basin C. A sample was collected on 11/17/08 from downgradient well #19 (located east of switchyard) and no tritium was detected, suggesting no release from secondary liner of Basin C. A vendor inspected the WMS liners, including Basin C, on 12/17/08 and indicated the integrity of liners appear to be in good condition.

A scope of work for liner leak detection has been received from the contractor and a PIF is in preparation for funding both the leak detection work, as well as anticipated repairs.Man. Act. 08-3781-03 and 04 have been issued to process and leak detect/repair, respectively.

6.11 Nonroutine planned release There was one nonroutine planned release. During the U2 refueling outage, fuel defects along with a minor steam generator manufacturing imperfection resulted in positive activity in the steam generators.

Prior to opening the steam relief valves, the quantity of steam was estimated and a permit was generated to account for the steam release.Page 19 of 44 SECTION 7.0 TABLES Page 20 of 44 Table 7.1 Site Liquid and Gaseous Batch Release Summary (2008)A.
