ENCLOSURE I 2003 ANNUAL RADIOACTIVE EFFLUENT RELEASE AND WASTE DISPOSAL REPORT JANUARY 2003 - DECEMBER 2003 This report provides information relating to radioactive effluent releases and solid radioactive waste shipments at the Palisades Nuclear Plant during the period of January 1, 2003, through December 31, 2003. The report is required by 10 CFR 50.36a(a)(2) and Technical Specification 5.6.3. The report format is detailed in the Offsite Dose Calculation Manual (ODCM), Appendix A.

2003 Plant Operatinq History Palisades went off-line on March 16, 2003, for a refueling outage. The unit returned to service on April 21, 2003, and remained in service for the rest of the year.

1. SuDplemental Information A. Batch Releases Information related to batch release of gaseous and liquid effluents is provided in Attachment 1.

B. Abnormal releases RV-1 120 Release (CAP033556)

On February 21, 2003, at 2018 hours0.0234 days <br />0.561 hours <br />0.00334 weeks <br />7.67849e-4 months <br />, an abnormal release of noble gas occurred in the auxiliary building when the relief valve (RV-1 120) from waste gas decay tank T-68B was removed from service for maintenance. This relief valve exhausts to the waste gas header.

The source of the release was the waste gas surge tank, T-67. This tank had a higher than normal radioactivity content due to a recent plant power escalation. When the system was breeched, gas flowed from the waste gas header into the auxiliary building, and was ultimately released through the plant stack system (as detected by the stack gas normal range noble gas monitor). A conservative estimate determined that a total of 3.72E-01 Curies were released. The resultant dose to the most conservative site boundary location was 2.63E-05 millirads beta air dose, and 8.85E-06 millirads gamma air dose. The release was quantified and documented in Stack Gas Analysis Record 03-009-ST.

C. Lower Limits of Detection (LLD's) for gaseous and liquid effluents are provided in Attachment 5.

D. Results of the 2003 Radiochemistry Cross Check Program with Analytics are shown in Attachment 6. Results were in agreement for all isotopes on all three detectors. There were a total of 272 measurements made.

E. Radioactive Effluent Monitoring Instrumentation The ODCM, Appendix A, requires that any gaseous or liquid effluent monitor out of service for greater than 30 days be included in this effluent report. In 2003, no radioactive effluent monitoring instrument channels were inoperable for more than 30 days. However, RIA-2327, the high range noble gas channel (one of the channels associated with the stack gas effluent system) was out of service for 16 consecutive days in August 2003. As a result of this inoperability, a special report was submitted to the NRC detailing the cause of the event. This report was submitted on September 4, 2003, under docket 50-255.

2. Gaseous Effluents Attachment 2 lists and summarizes all gaseous radioactive effluents released during the reporting period. The unidentified beta was 1.01 E-05% of the total release.

Gaseous effluents (noble gases) and resultant beta and gamma doses to the site boundary in 2003 were approximately 72% higher than the previous year. The total fission and activation gases released in 2003 were also 72% higher than that of 2002.

The higher gaseous effluent releases in 2003 were a result of the two fuel failures experienced in fuel cycle 16. The majority of the release occurred during the first quarter of the year during the containment purge activity at the start of the refueling outage. Organ dose (long-lived particulates and iodine) was 60% higher than 2002, due to the same factors that influenced the beta and gamma site boundary doses.

3. Liquid Effluents Attachment 3 lists and summarizes all liquid radioactive effluents released during the reporting period. The unidentified beta was 1.48E-04% of the total release.

Overall, whole body and organ dose from liquid effluents released during 2003 were 277% higher than those of 2002. Total release curies in 2003 were 686% higher than 2002, while liquid release volumes were nearly identical for both years.

The increased dose and curies released for 2003 was a result of the polishing demineralizer being out of service. Release tanks were not re-circulated through the demineralizer prior to release to further reduce activity concentration during the fourth quarter of 2003. The demineralizer has been returned to service and is available for processing tanks prior to release in 2004.

4. Estimate of Uncertainty Both the Gaseous and Liquid Summation of Release data sheets include an estimate of the uncertainty associated with the measurement of radioactive effluents. These estimates are based on a statistical analysis of a series of sample results as described in the ODCM, Appendix A. These results are listed in the "Est Total Error %" columns on the Gaseous Summation Report (Attachment 2) and the Liquid Summation Report (Attachment 3).
5. Solid Waste Attachment 4 summarizes all solid radwaste classification, sources, volume shipped, curie and nuclide content. Radwaste shipments were made either to Barnwell Waste Management Facility in Barnwell, South Carolina, or to Envirocare of Utah, Inc. In 2003, the waste volume and the curies shipped were lower than that of 2002. Less waste was shipped off site for processing, and very little resin waste was disposed of in 2002, accounting for the lower values in volume and curies.
6. Summary of Radiological Impact on Man Potential doses to individuals and populations were calculated using GASPAR and LADTAP computer program codes. The quarterly values for curies released were input for each nuclide and summarized as follows:

A. The maximum total body dose to an individual in unrestricted water-related exposure pathways was:

First Quarter - 2.49 E-04 millirem (adult)

Second Quarter - 3.92 E-04 millirem (adult)

Third Quarter - 7.31 E-08 millirem (adult)

Fourth Quarter - 6.49 E-04 millirem (teenage)

The maximum organ dose was:

First Quarter - 3.05 E-04 millirem (teenage bone)

Second Quarter - 5.02 E-04 millirem (teenage liver)

Third Quarter - 7.31 E-08 millirem (adult liver)

Fourth Quarter - 1.04 E-03 millirem (teenage bone)

Page 3 of 5

B. The offsite air doses at site boundary (0.48 mi SSE) due to noble gases was:

First Quarter - 4.36 E-03 millirad beta and 1.44 E-03 millirad gamma Second Quarter - 2.64 E-04 millirad beta and 5.41 E-05 millirad gamma Third Quarter - 3.78 E-05 millirad beta and 1.12 E-05 millirad gamma Fourth Quarter - 5.32 E-05 millirad beta and 1.78 E-05 millirad gamma The maximum noble gas offsite air dose to the nearest residence (0.50 mi S) for beta and gamma occurred during the first quarter, 2.83 E-03 millirad and 9.33E-04 millirad respectively.

C. The most restrictive organ dose to an individual in an unrestricted area (based on identified critical receptors) from gaseous effluent releases were:

First Quarter - 3.09 E-02 millirem (infant thyroid)

Second Quarter - 1.55 E-02 millirem (infant thyroid)

Third Quarter - 5.66 E-03 millirem (child thyroid Fourth Quarter- 5.52 E-03 millirem (child thyroid)

D. Integrated total body doses to the general population and average doses to individuals within the population from liquid effluent release pathways to a distance of 50-miles from the site boundary were:

First Quarter - 1.90 E-03 person-rem and 1.44 E-06 millirem Second Quarter - 2.62 E-03 person-rem and 1.98 E-06 millirem Third Quarter - 8.55 E-07 person-rem and 6.48 E-10 millirem Fourth Quarter- 2.92 E-03 person-rem and 2.21 E-06 millirem E. Integrated total body doses to the general population and average doses to individuals within the population from gaseous effluent release pathways to a distance of 50 miles from the site boundary were:

First Quarter - 2.35 E-02 person-rem and 1.78 E-05 millirem Second Quarter - 2.50 E-02 person-rem and 1.89 E-05 millirem Third Quarter - 2.01 E-02 person-rem and 1.52 E-05 millirem Fourth Quarter- 1.96 E-02 person-rem and 1.48 E-05 millirem

7. Process Control Program (PCP)

There were no changes made to the Process Control Program in 2003.

8. Offsite Dose Calculation Manual (ODCM)

The ODCM was revised in January 2003. Attachment 7 contains the ODCM, Revision 18, and the 50.59 review, per the requirements of Technical Specification 5.5.1.c.3.

Page 4 of 5

Revision 18 to the ODCM involved changes as a result of use of the 2002 Land Use Survey. The Land Use Survey is used to ensure that effluent dose is calculated accurately. These changes maintain the level of radioactive effluent control required by 10 CFR 20.1302, 40 CFR Part 190, 10 CFR 50.36a, and Appendix I to 10 CFR Part 50, and do not adversely impact the accuracy of effluent dose, or setpoint calculations.

The following tables were changed:

1) Update of Table 1.4, 2002 Palisades Land Use Census
2) Update of Table 1.4a, 2002 Palisades Land Use Census - Critical Receptor Items Page 5 of 5
