Dear Sir or Madam:
Entergy Nuclear Operations, Inc. is submitting the enclosed Radiological Environmental Operating Report for the Big Rock Point Independent Spent Fuel Storage Installation (ISFSI). This report was prepared in accordance with the requirements of 10 CFR 50, Appendix I, Section IV.B, and Defueled Technical Specification 6.6.2. The period covered by the enclosed report is January 1,2012, through December 31, 2012.
This letter contains no new commitments and no revision to existing commitments.
Sincerely, OWG/bed
Enclosure:
Big Rock Point 2012 Annual Radiological Environmental Operating Report Attachment 1: Sample Collection Anomalies Attachment 2: Environmental Sample Schedule and Sample Location Maps Attachment 3: Radiological Environmental Monitoring Program Data for BRP ISFSI CC Administrator, Region Ill, USNRC BRP ISFSI Inspector, USNRC NMSS Project Manager, USNRC
ENCLOSURE Big Rock Point 2012 Annual Radiological Environmental Operating Report Introduction The 2012 Big Rock Point (BRP) Annual Radiological Environmental Operating Report provides a summary and data interpretation of the BRP Radiological Environmental Monitoring Program (REMP) as conducted during the 2012 reporting period. Reporting requirements are detailed in the BRP Defueled Technical Specification 6.6.2 and Offsite Dose Calculation Manual (ODCM).
The BRP ODCM contains the requirements for the REMP. The radiological environmental monitoring sampling requirements are greatly reduced from the plant's operating period, and now only encompass Independent Spent Fuel Storage Installation (ISFSI) operations.
All samples were collected during the monitoring period with no anomalies.
Tables 1, 2, and 3, of this enclosure, provide a summary of 2012 BRP REMP sample requirements and results.
I1. Discussion and Interpretation of Results A. TLDs - Gamma Dose The BRP Gamma Dose Assessment Program consists of eleven thermoluminescent dosimeter (TLD) locations: Four at the outside perimeter of the ISFSI (locations: BR-18, BR-19, BR-20, and BR-21), four at the ISFSI protected area fence line (locations: BR-22, BR-23, BR-24, and BR-25), and three control TLDs, approximately 13 miles out (locations: BR-5 Petoskey, BR-6 Boyne City, and BR-7 Ironton). These are the only TLDs required for ISFSI operation. The additional locations are no longer applicable because they no longer exist. Environmental gamma doses are measured quarterly by placement of one TLD badge per designated location. Detailed sample station identification and location information is provided in Attachment 2.
For 2012, the average quarterly gamma readings were:
24.9 millirem for protected area fence TLDs, 18.3 millirem for ISFSI outside perimeter TLDs, and 17.9 millirem for the control TLD locations.
The comparative evaluation of the protected area fence line quarterly TLD mean and the ISFSI outside perimeter TLD mean measured in 2012, are slightly higher from that of 2011, but still within the statistical standard deviation.
Page 1 of 3
ENCLOSURE Big Rock Point 2012 Annual Radiological Environmental Operating Report A comparative evaluation was also completed of the 2012 offsite control TLD data to the ISFSI outside perimeter TLD data. There was excellent correlation between the off-site control TLDs and the ISFSI outside perimeter TLDs. There was no significant difference between the 2011 and 2012 control data.
Each TLD badge contains a 4-zone calcium sulfate (CaSO 2 ) phosphor wafer (the wafer also includes an additional backup/reserve read-out zone). Sensitivity for the multi-zone TLDs are 1.0 millirem with a linear response to 1000 rem.
B. Air Samples The BRP REMP no longer requires that airborne surveillance be conducted.
C. Milk The BRP REMP no longer requires that milk samples be collected.
D. Lake Water The BRP REMP no longer requires that lake water samples be collected.
E. Drinking Water The BRP REMP no longer requires that drinking water samples be collected.
F. Crops The collection of food crops/vegetation is not required by the BRP REMP.
G. Sediment The BRP REMP no longer requires that well water samples be collected.
H. Aquatic Biota The collection of aquatic biota (algae and periphyton) is no longer required by the BRP REMP.

ENCLOSURE Big Rock Point 2012 Annual Radiological Environmental Operating Report Ill. Assessment of BRP ISFSI Operational Environmental Impact Review and comparison of the 2012 BRP radiological environmental monitoring data to previous data shows that the parameters analyzed support the conclusion that ISFSI operations have had minimal environmental impact.

If specimens are unobtainable due to sampling equipment malfunction, every effort shall be made to complete corrective action prior to the end of the next sampling period. All deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report pursuant to the Reporting Requirements of ODCM. Alternative media and locations may be chosen for any particular pathway if designated locations or media are not available, and appropriate substitutions are made within 30 days in the radiological environmental monitoring program.
