Duke Power Company, LLC d/b/a Duke Energy Carolina, LLC Catawba Nuclear Station, Units 1 and 2 Docket Nos. 50-413 and 50-414 2005 Annual Radiological Environmental Operating Report -Errata Catawba Nuclear Station transmitted its 2005 Annual Radiological Environmental Operating Report pursuant to Technical Specification 5.6.2 and Selected Licensee Commitment 16.11-16 on May 11, 2006.During a subsequent review, it was discovered that the bound copies of this report did not contain the correct Figure 3.1, "Concentration of Gross Beta in Air Particulate" in Section 3.1, Airborne Radioiodine and particulates.

The recipients of the bound copy of this report should replace the first page in Section 3.1, which contains the incorrect figure (Concentration of Tritium in Drinking Water) with the attached page which contains the correct figure (Concentration of Gross Beta in Air Particulate).

The report transmitted on the compact discs contained the correct figure.Any questions should be directed to Kay Nicholson at 803.831.3237.

com 0 p 3.1 AIRBORNE RAD!OIODINE AND PARTICULATES In 2005, 265 radioiodine and particulate samples were analyzed, 212 from four indicator locations and 53 at the control location.

Particulate samples were analyzed weekly for gamma and gross beta. Radioiodine samples received a weekly gamma analysis.Figure 3.1 shows individual sample gross beta results for the indicator location with highest annual mean and the control location samples during 2005. The two sample locations' results are similar in concentration and have varied negligibly since preoperational periods.There were no detectable gamma emitters identified for particulate filters analyzed during 2005. Table 3.1-A shows the highest indicator annual mean and control location annual mean for gross beta in air particulate.

There was no detectable 1-131 in air radioiodine samples analyzed in 2005. Table 3.1-B shows the highest indicator annual mean and control location annual mean for 1- 131 since 1984 (preoperational period).K-40 and Be-7 that occur naturally were routinely detected in charcoal cartridges collected during the year. Cs-137 activity was not detected on any cartridges in 2005. Cs-137 detection on the charcoal cartridge was determined in 1990 to be an active constituent of the charcoal.

A similar study was performed in 2001 again yielding this conclusion.

Therefore, any Cs-137 activities were not used in any dose calculations in Section 4.0 of this report.Figure 3.1 There is no reporting level for gross beta in air particulate pCi/m3 1.00E-01 9.OOE-02 -8.OOE-02 --7.OOE-02 6.OOE-02 5.OOE-02 --4.OOE-02 --3.OOE-02 -2.OOE-02 1.OOE-02 O.OOE+O0 *1984 Concentration of Gross Beta in Air Particulate 1986 1988 1990 1992 1994 1996 1998 2000 2002 2004--- Indicator Location U Control Location
