FLORIDA POWER AND LIGHT COMPANY ST. LUCIE UNITS #1 AND #2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2006 THROUGH DECEMBER 31, 2006 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 ten 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 Iodine-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.

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.

The VISITOR received exposure from each of the two reactors on the Site. Actual Met Data was used to calculate Visitor Dose for Calendar Year 2006.

VISITOR DOSE RESULTS FOR CALENDAR YEAR 2006 were:

DOSE Gas Particulate Dose NOBLE GAS mrad & Iodine Dose mrem Gamma Air Dose 1.85E-03 Bone 1.76E-05 Beta Air Dose 8.71 E-04 Liver 3.18E-04 Thyroid 3.05E-04 Kidney 3.03E-04 Lung 3.03E-04 GI-LLI 2.96E-04 Total Body 5.68E-04

8. Offsite Dose Calculation Manual (ODCM) Revision(s):

The ODCM was revised two times during 2006. The first revision was to clarify operational and calibration requirements for the vent flow rate monitors and make various administrative changes to tables, appendices and page number references. The second change was to create an additional liquid release flowpath to the intake canal from the construction dewatering that will be required for the Independent Spent Fuel Storage Installation project.

9. Solid Waste and Irradiated Fuel Shipments:

No irradiated fuel shipments were made from the site.

Common Solid waste from St. Lucie Units 1 and 2 were shipped jointly.

SOLID WASTE SUPPLEMENT NOTE 1: The total radionuclide activity and composition of solid waste shipped from the St. Lucie Plant, Units 1 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 (5/11/83) 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 and non-compressible waste (22,627 cubic feet, 1.21 E+1 curies) were made from the St. Lucie Plant to the volume reduction facilities. These materials were shipped via "Sole Use Truck". in non-specification, general design containers.

NOTE 6: The volume and activity listed for "Spent Resin, Process Filters" 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 contracted vendor as dewatered bead resin and process filters for volume reduction prior to final disposal at the licensed disposal facility. During the reporting period, four (4) shipments of bead resin and process filters (338.1 cubic feet, 1.78E+2 curies) were made from the St. Lucie Plant to the contract vendor for volume reduction and disposal.

NOTE 7: The volume and activity listed for "Other" (Reactor Head and Pressurizer) represent the quantity of material that during the reporting period was sent to the licensed disposal facility. This material was shipped to a contracted vendor for volume reduction prior to final disposal at the licensed disposal facility.

Unplanned Release of 2A Gas Decay Tank Description of the event:

On October 6, 2006, following maintenance on the 2A Gas Decay Tank, the tank was pressurized to 120# with nitrogen. Later, the field operator identified the 2A GDT had dropped to 70#. The Operating Crew entered the Waste Gas Off-Normal procedure, 2-0530030, to investigate the

-ause of the leakage. Valve V6580 was identified as leaking past its closed seat due to a mis-adjusted reach rod. Maintenance made an adjustment to the reach rod for V6580 and all leakage stopped. Subsequent monitoring of the tank's pressure confirmed that the leak had been aorrected.

Actions taken to prevent a recurrence:

Unplanned Release of the 1B GDT Description of the event:

On 4/15/06, the Unit 1 Control Room was notified of a loss of 16 psig from the 1 B Gas Decay Tank(GDT). At that time, it did not meet the threshold of an unplanned gas release as indicated in the off-normal procedure, however a leak search was commenced. The oxygen analyzers, waste gas compressors and accessible piping in the RAB were checked for leaks, none were found.

Pressure held steady for the day, but in the afternoon, it was identified the 1 B GDT had lost an additional three pounds, which met entry criteria for the off-normal. The off-normal procedure was entered, and the gas analyzers were isolated, and pressure stabilized. Engineering assisted Operations with the search, but could not determine the location of the leak.

After three days of extensive leak searches, the gas analyzers were returned to service and the system is holding pressure. Therefore, the location of the leak is unknown.

Actions taken to prevent a recurrence:

The Unit 1 and 2 Off-normal operating procedures for gas leakage have been revised to clarify operator actions that need to be taken in the event of GDT pressure loss.

Consequences of the unplanned release:

FLORIDA POWER AND LIGHT COMPANY ST. LUCIE UNITS #1 AND #2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY 1, 2006 THROUGH DECEMBER 31, 2006 ATTACHMENT B Radiation Monitors Out of Service for Greater than 30 Days Radiation Monitors Out of Service for Greater Than Thirty Days Unit 1 Liquid Waste Discharge Monitor The Unit 1 Liquid Rad Waste Discharge monitor has been out of service for greater than 30 days several times during the year. The monitor was declared out of service due to failure of the flow switch internal to the radiation monitor skid. The flow switch detects ifthere is sample flow going to the detector well, and to annunciate when the liquid waste discharge flow drops below a pre-set value, signaling the end of the liquid release. This flow switch has been clogging up with debris during the liquid discharges, and not annunciating in the control room when required. This switch has been replaced multiple times, with the same results. A back-flushing procedure was implemented, but has not had consistent positive results. Replacement of the switch with a new design that has no moving parts will be required. This replacement is currently under investigation by the St. Lucie Engineering Department.

Unit 1 Fuel Handling Building Radiation Monitor The Unit 1 Fuel Handling Radiation Monitor was declared out of service on 9/11/2006 due to a low flow alarm. The photohelic gauge was determined to be cause of the failure. A replacement photehelic gauge was removed from stock and installed. This replacement part was found to be defective. No additional replacements parts were available on site and the manufacturer was unable to supply additional parts in a timely manner. A new photohelic gauge was installed on 11/8/2006. The monitor was calibrated and returned to service on 11/9/2006.

Jnit 2 Fuel Handling Building Radiation Monitor The Unit 2 Fuel Handling Building radiation monitor was declared out of service on 7/23/2006, after the Control Room received multiple alarms for the monitor. The initial repairs attempts were unsuccessful due to the badly corroded condition of the monitor due to extended exposure to the moist salt air environment. The building that houses the monitor is not air conditioned and is force ventilated by outside air. This is original plant design and is the main contributor to the degradation of the monitor.

Vlaintenance is continuing to attempt repairs to the monitor to replace affected components and

<eep the monitor operating, but the long term plan is to replace the monitor skid and provide an Bnvironmentally controlled enclosure for the monitor. Change Authorization Request 04-056 has

)een generated to provide replacement of the radiation monitor skid and installation of an air

,onditioned enclosure.

Inadvertent Release to On-site Settling Basin On August 22nd, 2006, a sample taken from the East Settling Basin located on the Owner

-ontrolled Property, inside of the Protected Area, was found to have tritium activity present at 3.39E-6 uCi/ml. Previous samples taken from this basin had been less than minimum detectable activity. Follow-up samples and investigation into this matter determined that a valve leak on a montainment spray line in an underground vault had migrated to the settling basin. The valve leak Nas repaired.

State and local authorities, as well as the NRC, were notified of the leak. The settling basin is being monitored for activity weekly.
