Dear Sir or Madam:
In accordance with 10 CFR 72.44(d)(3), Entergy Nuclear Operations, Inc. is submitting the annual independent spent fuel storage installation (ISFSI) radioactive effluent release report for Big Rock Point for the period from January 2011, through December 2011.
This letter contains no new commitments and no revision to existing commitments.
Sincerely, owg/bed

Independent Spent Fuel Storage Installation Annual Radioactive Effluent Release Report CC Administrator, Region Ill, USNRC BRP Decommissioning Inspector, USNRC NMSS Project Manager, USNRC
ATTACHMENT INDEPENDENT SPENT FUEL STORAGE INSTALLATION ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT BIG ROCK POINT January 2011 December 2011 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 10 CFR 72, and the Certificate of Compliance No. 72-1026, issued by the Nuclear Regulatory Commission (NRC).
II.
EFFLUENT LIMITS AND CONTROLS The ISFSI operates under effluent control limits as required by 10 CFR 72.104.
However, the design of the sealed storage canisters at the ISFSI precludes any gaseous or liquid effluent releases.
III.
RADIOLOGICAL EFFLUENT RELEASES As noted in Section Il, 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 indicate any release of radioactivity from the ISFSI.
IV. ISFSI ENVIRONMENTAL MONITORING PROGRAM The BRP Radiological Environmental Monitoring Program (REMP) is described in the Offsite Dose Calculation Manual (ODCM),Section I, Subsection 4.0. The ISFSI Environmental Monitoring Program, which is contained within the BRP REMP, consists of thermoluminescent dosimeters (TLDs) at four locations along the perimeter of the ISFSI site, and three control TLD5 10.5 to 12.6 miles from the site.
Quarterly TLD5 are read quarterly, as reflected in Section VI. Quarterly measurements are compared to control measurements to evaluate compliance with 10 CFR 72.104. The results for the ISFSI TLD5 and the average of the control TLDs measured in 2010 are summarized in Section VI.
V.
SAMPLE ANOMALIES None.
