ENCLOSURE 1 FPL ENERGY POINT BEACH, LLC POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 2007 ANNUAL MONITORING REPORT 1.0 RADIOACTIVE AIRBORNE RELEASES Corrections to Tables 3-2 and 3-3 (2000 through 2005)

During the years 2000 through 2005, F-1 8 was reported in Table 3-3 "Isotopic Composition of Airborne Releases," and used to calculate the total particulate curies released in Table 3-2, "Radioactive Airborne Effluent Release Summary." Because particulate F-18 has a short half-life, it should not have been reported in either table during those years. The curies of airborne particulates released have been recalculated.

The originally reported values and the corrected particulate values are presented in Table 1.

5.0 ADDITIONAL REPORTING REQUIREMENTS 5.1 Revisions to the PBNP Effluent and Environmental Proqrams The ODCM was revised in 2007 to include the modification (ALPS - Advanced Liquid Processing System) to the liquid waste treatment system. The wastewater treatment system that serves the radiologically controlled area of the plant has been modified by replacing the evaporator system with an ion exchange system.

6

5.2 Interlaboratory Comparison Program Environmental, Inc, Midwest Laboratory, the analytical laboratory contracted to perform the radioanalyses of the PBNP environmental samples, participated in the Department of Energy's Mixed Analyte Performance Evaluation Program (MAPEP) as well as in the interlaboratory comparison studies administered by Environmental Resources Associates (ERA) during 2007. The ERA environmental crosscheck program replaces the Environmental Measurements Laboratory (EML) Quality Assessment Program which was discontinued. The results of these comparisons can be found in Appendix A of the AMR.

5.3 Special Circumstances No special circumstances report regarding operation of the explosive gas monitor for the waste gas holdup system was needed during 2007.

6.0 RADIOACTIVE LIQUID RELEASES The radioactive liquid release path to the environment is via the circulating water discharge.

A liquid waste treatment system in conjunction with administrative controls is used to minimize the impact on the environment and maintain doses to the public ALARA from the liquid releases.

6.1 2007 Circulating Water Radionuclide Release Summary Radioactive liquid releases via the circulating water discharge are summarized by individual source and total curies released on a monthly basis and presented in Table 6-1. These releases are composed of processed waste, wastewater effluent, and blowdown from Units 1 and 2. The wastewater effluent consists of liquid from turbine hall sumps, plant well house backwashes, sewage treatment plant effluent, water treatment plant backwashes, and the Unit 1 and 2 facade sumps.

6.2 2007 Isotopic Composition of Circulating Water Discharges The isotopic composition of circulating water discharges during the current reporting period is presented in Table 6-2. The noble gases released in liquids are reported with the airborne releases in Table 7-1. The isotopic distribution shows little change from 2006, with tritium down slightly from 2006 and close to 2005 value. Tritium continues to be the major radionuclide released via liquid discharges.

7.0 RADIOACTIVE AIRBORNE RELEASES The release paths to the environment contributing to radioactive airborne release totals during this reporting period were the Auxiliary Building Vent Stack, the Drumming Area Vent Stack, the Letdown Gas Stripper, the Unit 1 Containment Purge Stack, and the Unit 2 Containment Purge Stack. A gaseous radioactive effluent treatment system in conjunction with administrative controls is used to minimize the impact on the environment from the airborne releases and maintain doses to the public ALARA.

7.1 Radioactive Airborne Release Summary Radioactivity released in airborne effluents for 2007 are summarized in Table 7-1.

7.2 Isotopic Airborne Releases The monthly isotopic airborne releases for 2007, from which the airborne doses were calculated, are presented in Table 7-2. When both the equipment hatch and the Elevation 66' hatch are open during an outage, there is a measurable, convective flow out the upper hatch. Because this air is not filtered, whatever is measured in containment air is assumed to be carried out the hatch, through the fagade, and into the environment thereby contributing to the particulate effluent and the calculated dose.
