Nuclear Regulatory Commission Attention: Document Control Desk Washington, DC 20555-0001 South Texas Project Units 1 and 2 Docket Nos. STN 50-498, STN 50-499 Annual Update to the South Texas Project License Renewal Application (TAC NOS. ME4936 and ME4937)

Reference:

STPNOC Letter dated October 25, 2010, from G. T. Powell to NRC Document Control Desk, "License Renewal Application" (NOC-AE-10002607) (ML103010257)

By the referenced letter, STP Nuclear Operating Company (STPNOC) submitted an application to the Nuclear Regulatory Commission (NRC) for the renewal of Facility Operating Licenses NPF-76 and NPF-80, for South Texas Project (STP) Units 1 and 2, respectively. The application included the License Renewal Application (LRA), and the Applicant's Environmental Report - Operating License Renewal Stage. As required by 10 CFR 54.21(b), each year following submittal of the LRA, an amendment to the LRA must be submitted that identifies any change to the current licensing basis (CLB) that materially affects the contents of the LRA, including the Updated Final Safety Analysis Report (UFSAR) supplement.

This LRA update covers the period from September 1, 2011 through August 31, 2012. identifies STP LRA changes that are being made to: (1) reflect the CLB that materially affect the LRA; and (2) reflect completed enhancements and commitments. Changes to LRA pages described in Enclosure 1 are depicted as line-in/line-out pages provided in .

There are no regulatory commitments in this letter.

Should you have any questions regarding this letter, please contact Arden Aldridge, STP License Renewal Project Lead, at (361) 972-8243, or Ken Taplett, STP License Renewal Project regulatory point-of-contact, at (361) 972-8416.

Changes Reflected in Annual LRA Update Following Changes Materially Affect the LRA Reason for Change Affected LRA Sections or Tables Changed aging management program for fire dampers AMR Section 3.3.2.1.10 lines from B2.1.22, "Inspection of Internal Surfaces in Section 3.3.2.1.11 Miscellaneous Piping and Ducting Components" to B2.1.12, Section 3.3.2.1.12 "Fire Protection" because the B2.1.12 program manages fire Section 3.3.2.1.13 dampers that perform a fire barrier function. Section 3.3.2.1.14 Section 3.3.2.1.15 Table 3.3.1 Table 3.3.2-10 Table 3.3.2-11 Table 3.3.2-12 Table 3.3.2-13 Table 3.3.2-14 Table 3.3.2-15 Table 3.3.2-17 Added aging management program Open-Cycle Cooling Section 3.3.2.1.17 Water System B2.1.9 to LRA Section 3.3.2.1.17 to correct a previous omission.

Added the standby diesel generator starting air membrane Table 2.3.3-20 dryer and connection tubing to the scope of the standby Table 3.3.2-20 diesel generator in-scope components. The membrane dryers are credited for providing dry air (dry gas) environment.

Clarified that the steam generator secondary steam flow Table 3.1.2-4 restrictor venturies (component type SG Secondary Nozzles and Safe Ends), that are welded into the SG Secondary Nozzles, are only exposed to Secondary Water and not Plant Indoor Air.

Added the aging management program "Inspection of Table 3.3.1 Internal Surfaces in Miscellaneous Piping and Ducting Table 3.3.2-24 Components" (B2.1.22) to Gray Cast Iron and Copper Alloy Table 3.3.2-27

(>15% Zinc) components exposed to Raw Water Environment. The only assigned aging effect was for loss of material due to selective leaching. The aging effect of loss of material due to general, pitting crevice and microbiologically influenced corrosion is also required.

In addition, Item Number 3.3.1.81 in Table 3.3.1 deleted the reference to the "liquid radioactive waste system". This system is referred to as the "liquid waste processing system" for the South Texas Project.

The only assigned aging effect was for loss of material due to selective leaching. The aging effect of loss of material due to general, pitting crevice and microbiologically influenced corrosion is also required.

Item Number 3.3.1.81 in Table 3.3.1 deleted the reference to the "liquid radioactive waste system". This system is referred to as the "liquid waste processing system" for the South Texas Project.

~ Discussion~

uopper aiioy piping, Loss of material due to pitting, Open-Cycle Cooling Water Consistent with piping components, crevice, and microbiologically System (B2.1.9) NUREG-1801 for all and piping elements, influenced corrosion, and components except that a exposed to raw water fouling different aging management program is credited for components exposed to the raw water environment in the liquid radioactive wastc and essential cooling pond makeup, open loop auxiliary cooling, oily waste, liquid waste processing, and solid waste processing systems.

The aging of internal component surfaces exposed to the raw water environment of the l4qid Fadioactive waste and essential cooling pond makeup, open loop auxiliary cooling, oily waste, liquid waste processing, and solid waste processing systems is are managed by Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components (B2.1.22) aging management
