ENCLOSURE BIG ROCK POINT PLANT 2007 RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT

1. Introduction The 2007 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 2007 reporting period. Reporting requirements are detailed in the BRP Defueled Technical Specification, Section 6.6.3, and the Offsite Dose Calculation Manual (ODCM)

Section III, Subsection 2.0.

During 2006, site decommissioning activities were completed. The last activity was the final site survey which concluded that the former BRP Nuclear Plant met the radiological criteria for unrestricted use in accordance with 10 CFR 20.1402. On April 11, 2007, the BRP license was transferred to Entergy Nuclear Palisades, LLC.

The BRP ODCM,Section III, contains the requirements for the REMP. The radiological environmental monitoring sampling requirements are greatly reduced from the plant's operating period and now encompass independent spent fuel storage installation (ISFSI) operations.

There was a revision to the ODCM in 2007 that provided clarification of which thermoluminescent dosimeters (TLDs) are required for ISFSI-only operation.

Tables 1, 2 and 3 provide a summary of 2007 BRP REMP sample requirements and results. Detailed sample station identification and location information is included in Attachment 2.

Discussion and Interpretation of Results A. TLDs - Gamma Dose The BRP Gamma Dose Assessment Program consists of 11 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, 10.5 to 50 miles out (locations: BR-5 Petoskey, BR-6 Boyne City and BR-7 Traverse City).

Environmental gamma doses are measured quarterly and annually by placement of two TLD badges per designated location. Attachment 2 provides a description and diagram of TLD locations.

Page 1 of 3

For 2007 the average quarterly gamma readings were:

20.4 millirem for protected area fence TLDs, 15.2 millirem for ISFSI outside perimeter TLDs, and 17.8 millirem for the control TLD locations.

For 2007 the average annual gamma readings were:

96.8 millirem for protected area fence TLDs, 53.4 millirem for ISFSI outside perimeter TLDs, and 73.3 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 2007 are nominally elevated from that of 2006. This is comparable to the nominal elevation of the control TLD data for 2007.

A comparative evaluation was also completed of the 2007 offsite control TLD data to the ISFSI outside perimeter TLD data. The ISFSI outside perimeter mean, although lower than the offsite control mean, is not statistically different than the offsite control TLD mean.

Each TLD badge contains a 4-zone CaSO2 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.

Page 2 of 3

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.

III. Assessment of BRP's Operational Environmental Impact Review and comparison of the 2007 BRP radiological environmental monitoring data to previous data shows that the parameters analyzed support the conclusion that ISFSI operations have had minimal environmental impact.

Table 1 -1 Notations

a. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons. 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,Section III. 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.

b. One or more instruments, such as a pressurized ion chamber, for measuring and recording dose rate continuously may be used in place of, or in addition to, integrating dosimeters. The background dosimetry requirement also may be met through use of dosimeters shared with another facility, or from data provided by another entity, such as the State of Michigan, as appropriate for this site.

c. Gamma isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable to licensed materials in the effluents from the facility.

d. For the purposes of this table, a TAD is considered to be one phosphor; two or more phosphors or phosphor readout zones in a packet are considered as two or more dosimeters.

e. TLDs designated for ISFSI-only operation.
