INTRODUCTION Rancho Seco Nuclear Generating Station (RSNGS) Unit No. 1 is located in Sacramento County, California approximately 25 miles southeast of Sacramento and26 miles nprth~northeast of Stockton.
....... ;.c ................. , ..............  
Rancho Seco Unit No. 1 began commercial operation on April 17, 197;5. The single unit on the Rancho Seco site was a pressurized W<;lter reactor supplied by Babcock and Wilcox. The rated capacity was 913 megawatts electrlcaL Because of a public vote on June 6, 1989, Sacramento Municlpal Utility District (SMUD)shutdowrithe Rancho Seco Nuclear Generating Station and completed defueling operations on December 8, 1989. Transfer of the spentluel rod assemblies from the Spent Fuel Pooljnto dry storage at the Independent Spent Fuel $torage Installation (ISFSI) was completed on August 21, 2002.
;;.; ...........
Radiological dismantleh1eht oftne nuclear facility was completed ln December 2068 and the release of the Rancho Seco property, ex.ceptfor the area associated with the lnterirn,Onsite Storage Building (IOSB), from NRC license DPR~54 was i;ipprovedon September2!5, 2009. With.the completion of Phase I of decommissioning, the facility was placed in a SAFSTOR-type condition awaiting a suitable disposal option for the low~levelradioactive waste in storage in the IOSB. In 2014, the. Class B & c radioactive waste. stored in the IOSB was shipped to a suitable disposal-facility in Texas. Phase II of decommissioning {the IOSB and surrounding area) began in 20.15 and is expected to be completed in the first quarter of201'7.                     *                               * *

RSNGS ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER2016.

INTRODUCTION Rancho Seco Nuclear Generating Station (RSNGS) Unit No. 1 is located in Sacramento County, California approximately 25 miles southeast of Sacramento and26 miles nprth~northeast of Stockton.

Rancho Seco Unit No. 1 began commercial operation on April 17, 197;5. The single unit on the Rancho Seco site was a pressurized W<;lter reactor supplied by Babcock and Wilcox. The rated capacity was 913 megawatts electrlcaL Because of a public vote on June 6, 1989, Sacramento Municlpal Utility District (SMUD)shutdowrithe Rancho Seco Nuclear Generating Station and completed defueling operations on December 8, 1989. Transfer of the spentluel rod assemblies from the Spent Fuel Pooljnto dry storage at the Independent Spent Fuel $torage Installation (ISFSI) was completed on August 21, 2002.

Radiological dismantleh1eht oftne nuclear facility was completed ln December 2068 and the release of the Rancho Seco property, ex.ceptfor the area associated with the lnterirn,Onsite Storage Building (IOSB), from NRC license DPR~54 was i;ipprovedon September2!5, 2009. With.the completion of Phase I of decommissioning, the facility was placed in a SAFSTOR-type condition awaiting a suitable disposal option for the low~levelradioactive waste in storage in the IOSB. In 2014, the. Class B & c radioactive waste. stored in the IOSB was shipped to a suitable disposal-facility in Texas. Phase II of decommissioning {the IOSB and surrounding area) began in 20.15 and is expected to be completed in the first quarter of201'7. * * *

  • This-Annual Radioactive Effluent Releas~ Report (AR ERR) provides ,a summary ofgaseous anc;l liquid effluent releases made from Rancho Seco during the period of January 1 through December 3,1, 2016.

This report also:provides a summary of solid radioactili'e waste shipments during the.reporting period.

- .

In the currentcondition, there are nb radioactive liquids or liquid systems atthe facility. Radioactive material handing during limited remediation activities associated with the Phase II decommissioning effort, as well as subsequer:itwaste packaging activities were monitored with local air sampling as was the exhaust ventilation system. None of these portable air samples returned activity levels above. Ml)A,.

elimillatlng th~ potential of rc:idiocictive material being released from the facility in gaseous effluents.

Accordingly, there were no radioactive liquid or gaseous effluent releases made from Rancho *seco during the reporting period.

One shipment of solid radioactive waste was made during. the reporting period utilizing contract brokerage services This repOrt ha.s been prepared by SMUD to meet the requirements of Rancho seco Quality M<,mual (RSQM), Appendix A, Section 1.5.2:4 and Offsite Dose Calculation Manual (O[)CM) Revision 23, Step 6.10.1. It is presented in accordance with the format of USNRC Regulatory Guide 1.21. Radiation doses associated with radioactive effluents in liquids and gasses would be calc1,1lated for a hypothetical individual who receives the maximum possible exposure at or beyond the applicable Site Boundary, had any releases occurred. *

  • Since there were no releases of radioactivity in gaseous and liquid effluents during this report period, the limits' of 10 CFR20 were riot exceeded, nor were the numerical guidelines of 10 CFR 50, Appendix I ex.ceeded .. A 40 CFR 190 dose evaluation is not required be.cause radioactive effluent releases did not exceed twice the numerical guidelines of 10 CFR 50, Appendix L 1
