- SMUD March 31, 2015 DPG 15-089 REIRS Project Manager Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 Docket No. 50-312 Rancho Seco Nuclear Generating Station License No. DPR-54 Docket No. 72-11 Rancho Seco Independent Spent Fuel.Storage Installation License SNM-2510 10 CFR 20.2206 ANNUAL REPORT OF INDIVIDUAL MONITORING Attention: REIRS Project Manager In accordance with 10 CFR 20.2206, Rancho Seco Quality Manual Appendix A, Sections 1.5.2.1 and 1.5.2.2, we are providing the following information regarding monitoring radiation exposure for individuals and the annual exposure report.
Since late 2008, the only remaining radiation area at Rancho Seco is the area immediately adjacent to the stored fuel at the Independent Spent Fuel Storage Installation (ISFSI). Entries into the ISFSI radiation area are made infrequently, and for relatively short durations. Therefore, it is unlikely that any individual could receive an occupational radiation exposure greater than the values indicated in 10 CFR 20.1502(a) associated with the storage of spent nuclear fuel.
In 2014, the low-level radioactive waste stored in the Interim Onsite Storage Building (IOSB) was shipped for disposal at the Andrews, Texas Low-Level Radioactive Waste disposal facility' The activities associated with preparing this pre-packaged waste for transportation created the potential that an individual supporting the waste shipment project could receive an occupational radiation exposure greater than the values indicated in 10 CFR 20.1502(a), so personnel monitoring for radiation exposure was provided for employees' requiring access to the IOSB in 2014.
Note however, that none of the personnel monitored for radiation exposure exceeded the values requiring monitoring listed in 10 CFR 20.1502(a).

REIRS Project Manager DPG 15-089 In addition, no areas exist at the facility that are controlled for purposes of limiting intake of radioactive materials (i.e., no areas of airborne or loose contamination). Therefore, it is unlikely that any individual could receive an occupational radiation exposure greater than the values indicated in 10 CFR 20.1502(b) and no personnel monitoring for intake of radioactive materials was required or performed in 2014.
