Issued Combined Licenses for South Texas Project, Units 3 and 4

By letter dated September 20, 2007, STPNOC, acting on behalf of itself and the proposed owners, including NINA Texas 3 LLC, NINA Texas 4 LLC, and the City of San Antonio, Texas, acting by and through the City Public Service Board, submitted its application to the NRC for two Advanced Boiling Water Reactors (ABWRs) under Title 10 of the Code of Federal Regulations (10 CFR) Part 52, "Licenses, Certifications, and Approvals for Nuclear Power Plants." The STP 3 and 4 reactors will be located on the existing South Texas Project Electric Generating Station site in Matagorda County, Texas.

On January 24, 2011, NINA became the lead applicant for the STP 3 and 4 COL application, with STPNOC remaining as the operator. NINA assumed responsibility for design, construction, and licensing prior to operation of STP 3 and 4. STPNOC would be the licensed operator for the STP 3 and 4, as it currently is for the existing STP Units 1 and 2.

Application Information

The following table provides access to the COL Application that NINA submitted for South Texas Project, Units 3 & 4.

Some combined license applications were submitted with hyperlinks to various reference documents. Currently, the hyperlinks in those applications are not active. These hyperlinks represent an advanced feature that could be activated when the agency upgrades to web-based ADAMS, at which point these applications and documents such as the Final Safety Analysis Report and associated Technical/Topical Reports would be linked together. In the interim, and for those applications that do not have the hyperlink feature, the reference documents may be viewed under the Reference Documents section of the combined license application page. In addition, DVDs of the various documents are available by contacting the Public Document Room staff.
