St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 2003 Annual Radioactive Effluent Release Report Attached is the 2003 Annual Radioactive Effluent Release Report for St. Lucie Units 1 and 2. This report is being sent pursuant to 10 CFR 50.36a(a)(2) and Technical Specification (TS) 6.9.1.7. The report is for the 12-month period beginning January 1, 2003 and ending December 31, 2003.

Attachment A of the report is a summary of the June 12, 2003 unplanned release of the Unit 2 gas decay tank 2C event.

There were no revisions to the Offsite Dose Calculation Manual (ODCM).

Therefore, the ODCM will not be included in this submittal.

Please contact us with any questions regarding this submittal.

EFFLUENT AND WASTE DISPOSAL SUPPLEMENTAL INFORMATION

1. Regulatory Limits 1.1 For Liquid Waste Effluents A. The concentration of radioactive material released from the site shall be limited to 10 times the concentrations specified in 10 CFR Part 20 Appendix B, Table 2, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 micro-Curies/ml total activity.

B. The dose or dose commitment to a MEMBER OF THE PUBLIC from radioactive material in liquid effluents released, from each reactor unit, to UNRESTRICTED AREAS shall be limited to:

During any calendar quarter to <= 1.5 mrems to the Total Body and to <= 5 mrems to any organ, and During any calendar year to

<= 3 mrems to the Total Body and to <= 10 mrems to any organ.

1.2 For Gaseous Waste Effluents:

A. The dose rate in UNRESTRICTED AREAS due to radioactive materials released in gaseous effluents from the site shall be limited to:

For Noble Gases: <= 500 mrems/yr to the total body and

<= 3000 mrems/yr to the skin, and For Iodine-131, Iodine-133, Tritium, and all radionuclides in particulate form with half-lives greater than 8 days:

<= 1500 mrems/yr to any organ.

  • B. The air dose due to noble gases released in gaseous effluents from each unit, to areas at and beyond the SITE BOUNDARY shall be limited to the following:

During any calendar quarter, to <= 5 mrads for gamma radiation, and

<= 10 mrads for beta radiation and, during any calendar year, to <= 10 mrads for gamma radiation and

<= 20 mrads for beta radiation.

  • C. The dose to a MEMBER OF THE PUBLIC from lodine-131, Iodine-133, Tritium, and all radionuclides in particulate form, with half-lives > 8 days in gaseous effluents released, from each unit to areas at and beyond the site boundary, shall be limited to the following:

During any calendar quarter to <= 7.5 mrem to any organ, and During any calendar year to

<= 15 mrem to any organ.

  • The calculated doses contained in an annual report shall not apply to any ODCM Control. The reported values are based on actual release conditions instead of historical conditions that the ODCM Control dose calculations are based on. The ODCM Control dose limits are therefore included in Item 1 of the report, for information only.

EFFLUENT AND WASTE DISPOSAL SUPPLEMENTAL INFORMATION (Continued)

2. Effluent Concentration Limits (ECL)

Water: Ten times the 10 CFR Part 20, Appendix B, Table 2, Column 2, except for entrained or dissolved noble gases as described in 1.1.A of this report.

Air:

Release concentrations are limited to dose rate limits described in 1.2.A. of this report.

3. Average energy of fission and activation gases in gaseous effluents is not applicable.
4. Measurements and approximations of total radioactivity Where alpha, tritium, and listed nuclides are shown as zero Curies released, this should be interpreted as "no activity was detected on the samples using the ODCM Control analyses techniques to achieve required Lower Limit of Detection (LLD) sensitivity for radioactive effluents."

A summary of liquid effluent accounting methods is described in Table 3.1.

A summary of gaseous effluent accounting methods is described in Table 3.2.

SOLID WASTE SUPPLEMENT NOTE 1:

The total radionuclide activity and composition of solid waste shipped from the St. Lucie Plant, Units I and 2 are determined using a combination of qualitative techniques. In general, the St. Lucie Plant follows the guidelines outlined in the Low Level Waste Branch Technical Position (BTP) on Radioactive Waste Classification (5111/83) for these determinations. The most frequently used techniques for determining the total activity in a package are the "Dose-to-Curie" method and "Concentration Times Volume or Mass' calculations. Where appropriate. engineering type activation analyses may be applied. Since each of the above methodologies Involve, to some extent, qualitative parameters, the total activity Is considered to be an estimate.

The composition of radionuclides in the waste is determined by both on-site analyses for principal gamma emitters and periodic off-site analyses for other radionuclides. The on-site analyses are performed either on a batch basis or on a routine basis using reasonably representative samples as appropriate for the waste type. Off-site analyses are used to establish scaling factors or other estimates for radionuclides such as H3, C14, Fe55; Sr90, Tc99, 1129, Pu238, Pu239/240, Pu241, Am241, Cm242 and Cm243/244.

NOTE 2:

"Principal Radionuclides' refer to those radionuclides contained in the waste in concentrations greater than 0.01 times the concentration of nuclides listed in Table 1 or 0.01 times the smallest concentration of nuclides listed In Table 2 of 10 CFR 61.

NOTE 3:

'Type of Waste" is generally specified as described in NUREG 0782, Draft Environmental Impact Statement on 10 CFR 61. 'Licensing Requirements for Land Disposal of Radioactive Waste".

NOTE 4:

'Type of Container' refers to the transport package.

NOTE 5:

The volume and activity listed for "Dry Compressible Waste' represent the quantity of material that during the reporting period was sent to the licensed disposal facilities. Some of this material was shipped to a contract vendor for volume reduction or recycle prior to final disposal at the licensed disposal facilities. During the reporting period, seventeen (17) shipments of dry active waste, non-compressible waste, and resins (27,971 cubic feet, 1.05E+0 curies) were made from the St. Lucie Plant to the volume reduction facility. These materials were shipped via "Sole Use Truck' in non-specification, strong tight containers.

Unplanned Release of Unit 2 Gas Decay Tank 2C Description of the event:

On 6/12/03 prior to criticality, the Unit 2 waste gas system was realigned from the plant stack to the 2C gas decay tank (GDT) utilizing the 2B gas compressor and the gas surge tank (GST). During the time the system was aligned to the 2C GDT, the tank pressure dropped 23 psig. This constitutes an unplanned release per C-200 ODCM (Offsite Dose Calculation Manual).

Apparent Cause After placing the waste gas system in service, the on-shift unlicensed operator observed that the GST pressure had increased (exact value not known) and the "C" GDT pressure dropped with the "B" gas compressor in service. He notified the control room that the waste gas system was realigned back to the plant stack. Chemistry was notified of this system re-alignment. The drop in GDT gas pressure was due to the "2B" waste gas compressor was not working properly after return to service following maintenance and the auto gas analyzer was lined up to take a sample from the "C" GDT per Operating Procedure 2-0530020 "Waste Gas System Operation." The gas was directed back to the GST from the in service "C" GDT. While the auto gas analyzer was in service, the in service GDT provided a continuous sample flow being removed from it.

The GST design pressure is 40 psig. The GST relief valve V6778 setpoint is 20 psig per TEDB. Based on calculating the tank volumes, the pressure got high enough to open relief valve V6778 which goes to the relief valve collection header. Once the waste gas system was realigned to the plant stack, the gas in the gas surge tank and the vent gas collection

'header was discharged to the plant stack. This constitutes an unplanned, but monitored release. No plant or site radioactive release limits were exceeded during this event.

Corrective Actions

1. The waste gas system operating procedure was revised to add steps to vent the waste gas compressor head oiling system prior to placing a waste gas compressor in service following maintenance. Additional guidance was added to enhance awareness of the waste gas system operation during re-alignment activities to prevent possible unplanned releases.
2. The waste gas system surveillance procedures were revised to ensure operators drain the waste gas compressor accumulators weekly.
