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 2020 - December 2020 I. 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.

Ill. RADIOLOGICAL EFFLUENT RELEASES As noted in Section II, by desigrr;-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 TLDs 10.5, 10.8, and 12.6 miles from the site. Quarterly TLDs 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 TLDs and the control TLDs measured in 2019 are summarized in Section VI.

V. SAMPLE ANOMALIES None.

  • Control Location - Petoskey BRP-05 could not be located for 01 2020 (CR-PLP-2020-1107)

VII. CONCLUSIONS When compared to the control locations, it is evident that the dose from ISFSI operations during the reporting period does not exceed the limits as defined in 10 CFR 72.104.
