BIG ROCK POINT INDEPENDENT SPENT FUEL STORAGE INSTALLATION ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT January 1, 2006 through December 31, 2006

1. FACILITY DESCRIPTION The Independent Spent Fuel Storage Installation (ISFSI) is located within the Owner Controlled Area of the Big Rock Point (BRP) site. The storage of spent fuel at BRP meets the requirements of Certificate of Compliance (No. 72-1026) issued by the NRC.

II. EFFLUENT LIMITS AND CONTROLS This installation operates under effluent control limits as required by 10 CFR 72.44(d).

However, the design of the sealed storage canisters at the ISFSI precludes any gaseous or liquid effluent releases. This report is submitted in compliance with ISFSI Certification of Compliance 72-1026 and pursuant to 10 CFR 72.44(d)(3).

III. RADIOLOGICAL EFFLUENT RELEASES As noted in Section II, by design, there are no radioactive liquid or gaseous effluents originating from the ISFSI facility. The annual radiological surveillance performed during this reporting period did not find any indication of radioactive releases occurring from the ISFSI.

IV. ISFSI ENVIRONMENTAL MONITORING PROGRAM The Big Rock Point Radiological Environmental Monitoring Program (REMP) is described in the Off-Site Dose Calculation Manual (ODCM),Section I, Subsection 4.0. The ISFSI Environmental Monitoring Program which is contained within the Big Rock Point Radiological Environmental Monitoring Program (REMP), consists of thermoluminescent dosimeters (TLDs) at four locations along the perimeter of the ISFSI site and three control TLDs 10.5 to 50 miles from the site. These TLDs are read both annually and quarterly. The results for the ISFSI TLDs and the average of the control TLDs measured in 2006 are summarized in the following table.

There were no sample anomalies for 2006.
