STPEGS UFSAR 1.1-1 Revision 1 8
1.0 INTRODUCTION
AND GENERAL DESCRIPTION OF PLANT
1.1 INTRODUCTION
1.1.1 General
Information The Updated Final Safety Analysis Report (UFSAR) is submitted as a unique document in compliance with Regulatory Guide (RG) 1.70, "Standard Format and Content of Safety Analysis Reports," Rev. 2 and 10CFR50.71(e).
The original Final Safety Analysis Report (FSAR) was submitted in support of the application by Houston Lighting & Power Company (HL&P) for a Class 103 construction permit and facility operating license for the nuclear power plants designated as South Texas Project Electric Generating Station (STPEGS) Units 1 and 2.
The applicant was HL&P acting for itself and for City Public Service Board of San Antonio, Texas (CPS), Central Power and Light Company (CPL), and the city of Austin, Texas (COA) pursuant to the South Texas Project Participation Agreement between said four systems. HL&P, acting as project manager for the owners, was responsible for the design, construction, and operation of the STPEGS Units 1 and 2.
HL&P was responsible for securing a Class 103 construction permit and the operating licenses for the two units. The license was applied for under Section 103 of the Atomic Energy Act of 1954 as amended and the regulations of the U.S. Nuclear Regulatory Commission (NRC) as set forth in Title 10 of the Code of Federal Regulation (CFR). HL&P was involved in a limited amount of the design for the two units, reviewed the entire design, and initially had overall responsibility for STPEGS.
On November 17, 1997 responsibility for the operation of the South Texas Project was transferred from HL&P to the STP Nuclear Operating Company (STPNOC). STPNOC is a Texas non
-profit corporation created, controlled and financed by the Owners specifically for the purpose of operating STPEGS. This change was incorporated in the Unit 1 and Unit 2 Licenses via Amendments 93 and 80, respectively.
On August 31, 2002, HL&P (Reliant Energy) transferred its ownership interest in STPEGS and in STPNOC to Texas Genco, LP. This change was incorporated in the Unit 1 and Unit 2 Operating Licenses via Amendments 142 and 130, respectively.
On January 12, 2006, the NRC approved the transfer of ownership interest in STPEGS and in STP Nuclear Operating Company from Texas Genco, LP to NRG South Texas LP. This change was incorporated in the Unit 1 and Unit 2 Operating Licenses via Amendments 178 and 165, respectively.
American Electric Power Company, Inc. (AEP) is the parent company of CPL. Effective December 23, 2002, AEP sold the retail company portion of CPL to Centrica, and transferred the Central Power and Light/CPL names to Centrica as well. AEP renamed the remaining portions of CPL (generation and distribution interests) as "AEP Texas Central Company" (TCC). TCC sold its STP ownership interest to CPS and Texas Genco, LP on May 19, 2005.
STPEGS UFSAR 1.1-2 Revision 1 8 AEP Texas Central Company sold its ownership interest in STPEGS to Texas Genco, LP and CPS. License Amendments 172/160 became effective on May 19, 2005.
Texas Genco, LP sold its STP ownership interest to NRG South Texas LP. License Amendments 178 and 165 became effective on June 29, 2007
. The following entities currently own the STPEGS site, Units 1 and 2, and common station facilities:
City Public Service Board of San Antonio
City of Austin The site is located in south
-central Matagorda County west of the Colorado River, 8 miles north
-northwest of the town of Matagorda and about 89 miles southwest of Houston (Figure 1.2
-1). The exclusion area is shown on Figure 1
.1-1. The plant is designed as essentially two duplicate units. Description of one unit shall be interpreted as applying to both units. Differences between the two units, structures, systems, and components that are shared between the two units are specified in the appropriate section in the UFSAR and are summarized in Section 1.2.
The limited work authorization was granted on August 12, 1975, and nonsafety
-related construction was initiated in September 1975. A Class 103 construction permit was granted on December 22, 1975.
Fuel loading was completed in August 1987 and December 1988 for Units 1 and 2, respectively.
Commercial operation was declared in August 1988 and June 1989 for Units 1 and 2, respectively.
Each unit utilizes a four
-loop, pressurized water reactor (PWR) Nuclear Steam Supply System (NSSS) and supporting auxiliary systems designed by Westinghouse Electric Corporation.
The rated core thermal power of each unit is 3,853 MWt. Each unit was originally designed for a net electrical power output of 1,250 MWe at 3.5 in. Hg abs. backpressure.
Brown & Root, Inc. (B&R) was the initial engineer/constructor responsible for the design, engineering, equipment and material procurement, and construction of STPEGS Units 1 and 2. This included all plant structures, systems, and components other than those provided by the NSSS supplier, except for any promotional or other non
-plant-oriented structures that were done by outside contractors.
In September 1981, Bechtel Energy Corporation (BEC), at the request of HL&P, initiated action to assume responsibility for engineering, design, procurement, and construction management of STPEGS. Ebasco Services, Inc. was responsible for construction of STPEGS.
The Containment structure is a post
-tensioned concrete cylinder with steel liner plates, hemispherical top, and flat bottom. The cylinder portion and the hemispherical dome of the Containment are STPEGS UFSAR 1.1-3 Revision 1 8 prestressed by a Post
-Tensioning System consisting of horizontal and vertical tendons. Three buttresses are equally spaced around the Containment. The cylinder and the lower half of the dome are prestressed by horizontal tendons anchored 360 degrees apart by passing the intermediate buttresses. Each successive hoop is progressively offset 120 degrees from the one beneath it. The vertical U
-shaped tendons are continuous over the dome, forming a two
-way Post-Tensioning System for the dome. These tendons are anchored in a continuous gallery beneath the base slab which is provided for the installation and inspection of the vertical tendons.
1.1.2 Organization
of Contents This UFSAR has been organized according to the guidelines established by the regulatory staff of the NRC in their publication, "Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants" (Rev. 2, dated September 1975), and the regulations of the NRC set forth in 10CFR50.
Portions of this UFSAR may have to be clarified or revised during the course of operation and these changes will be made in the form of revisions. The revision process will contain the following procedures:
- 1. When a change is made to the UFSAR text, those pages affected will be marked with the revision number in the lower right
-hand corner and a vertical line in the right
-hand margin next to the material affected.
- 2. Figures will be revised by indicating the revision umber in the lower right
-hand corner of the page.
Lists of acronyms, abbreviations, and names of major buildings and structures used throughout this UFSAR are given in Tables 1.1
-1, 1.1-2, and 1.1-3, respectively. Figures 1.1
-2 and 1.1-3 provide piping and instrumentation symbols used on engineering drawings throughout the UFSAR.
1.1.3 Licensing
Basis and Configuration Control of the UFSAR STP controls the UFSAR in compliance with the requirements of 10CFR50.71 (e). The UFSAR is regarded as the primary document describing the licensing basis of the station, although the comprehensive definition of the Current Licensing Basis may include other documents as described in station procedures.
1.1.3.1 Non-Licensing Basis Information in the UFSAR
- Information contained in the UFSAR that meets the criteria listed below is not regarded as constituting current licensing bases requirements and is maintained in the UFSAR only for historical or informational purposes.
- 1. Historical information in Table 7.1
-2, which was included on a one
-time basis to provide general perspective of the facility or to provide a comparison with other facilities.
- 2. General arrangement drawings are listed in Table 1.2
-1. As noted in R.G. 1.70, the general arrangements are included "to provide a reasonable understanding of the general layout of the plant."
STPEGS UFSAR 1.1-4 Revision 1 8 1.1.3.2 Changes to Electrical, Instrumentation, and Controlled Drawings
- electrical, instrumentation and controlled drawings listed in Tables 1.7
-1, 1.7.2 and 1.7
-3 of the UFSAR; and controlled drawings relocated to the STP Controlled Drawing Manual (P&IDs, single line diagrams, logic diagrams, etc.) are provided to aid in understanding the design, function and method of performing the function of a component, system or structure described in the text of the UFSAR.
These drawings provide detailed information for the purpose of plant configuration control documentation. As a result, more detail exists in these drawings than is necessary to support the safety analysis in the UFSAR. Therefore, changes to the electrical, instrumentation and controlled drawings listed in Tables 1.7
-1, 1.7-2 and 1.7-3 of the UFSAR; and controlled drawings relocated to the STP Controlled drawing Manual that meet criteria 1, 2, and 3 AND at least one of criteria 4, 5, and 6 below have been generically reviewed pursuant to 10CFR50.59 and are not considered changes to the UFSAR.
- 1. The change does not:
Affect the reactor coolant system pressure boundary. Affect the function of the systems, structures or components required to achieve or maintain safe shutdown.
Affect the function of the systems, structures or components required to mitigate the consequences of an accident, including fire.
Affect the function of the systems, structures or components described in the safety analysis report for regulatory compliance (e.g., AMSAC).
- 2. The change does not affect calculational results used to support the conclusions in the safety analysis report.
- 3. The changes meets design specifications. Design specifications are the criteria or range of criteria for controlling parameters for assurance that design safety functions are met.
- 4. The change is made to systems, structures, or components that are part of the current plant configuration but which are not described or referred to in the text of the UFSAR. Failure of these systems, structures or components are evaluated to not have any direct or indirect effect on the design, function of method of performing the function of systems, structures or components as described in the safety analysis report.
- 5. The change involves additions or deletions of systems, structures or components to the plant's configuration that does not alter the design, function or method of performing the function as described in the text of the UFSAR.
- 6. The change involves reference information on the engineering document (s) that does not require or result in a corresponding physical change to the existing configuration of the system, structure or component, nor is found in or referred to in the text of the safety analysis report.

. The NSSS is a Westinghouse Electric Corporation four loop PWR.
1.2.2.2.1 Reactor Core and Control Rods
- The reactor has a multi
-region-cycled core. The fuel rods are Zircaloy tubes containing slightly enriched uranium dioxide fuel. The fuel assembly is of the canless type basically consisting of guide thimbles attached to top and bottom grids, and top and bottom nozzles. The fuel rods are held by spring clip grids which provide very stiff support.
The integrity of the fuel rods is ensured by designing to prevent excessive fuel temperatures, excessive internal rod gas pressures due to fission gas releases, and excessive cladding stresses and strains.
Rod cluster control assemblies (RCCAs) are inserted into guide thimbles of certain fuel assemblies for reactor control. The control rods use hafnium or silver
-indium-cadmium as the neutron absorber. Above the core, each cluster of absorber rods is attached to a spider connector and drive shaft that is STPEGS UFSAR 1.2-3 Revision 1 8 raised and lowered by a drive mechanism mounted on the reactor vessel head. Upon reactor trip, the RCCAs are inserted into the core by gravity.
The control rods are designed to shut down the reactor with adequate margin under conditions of normal operation and anticipated operational occurrences, thereby ensuring that specified fuel design limits are not exceeded.
A soluble neutron absorber is utilized for long
-term reactivity control and refueling operations.
The reactor core rated thermal power is 3,853 MWt core power plus 21 MWt reactor coolant pump (RCP) energy.
1.2.2.2.2 Reactor Vessel and Internals
- The reactor vessel and internals contain and support the fuel. The vessel has a low
-alloy carbon steel hemispherical head and bottom, and is clad inside with stainless steel.
1.2.2.2.3 Reactor Coolant System:
High-pressure light water serves as the coolant, neutron moderator, reflector, and solvent for the neutron absorber. The Reactor Coolant System (RCS), comprised of four parallel loops (each with a RCP and a steam generator [SG]), is used to transfer the heat generated in the core to the SGs using RCPs to circulate the water. RCS pressure is maintained by means of a pressurizer attached to the hot leg of one of the loops. The RCS is designed to circulate borated demineralized water at temperatures, pressures and flow rates consistent with the design thermal and hydraulic performance of the NSSS.
1.2.2.2.4 Residual Heat Removal System
- The Residual Heat Removal System (RHRS) is used to cool down the RCS following reactor shutdown after the RCS temperature and pressure have been reduced by the Auxiliary Feedwater System (AFWS) and by dumping steam during cooldown. The entire system is located within the Containment. Following cooldown, the RHRS removes decay heat from the reactor core to maintain the desired temperature. The system consists of three independent trains, each having its own pump and heat exchanger (HX).
1.2.2.2.5 Chemical and Volume Control System: The Chemical and Volume Control System (CVCS) maintains the coolant inventory in the RCS. The functions of the CVCS are purification of the reactor coolant, control of the RCS chemistry, regulation of the reactor coolant inventory, control of reactivity in the core, and seal water injection for the RCPs.
The CVCS consists of charging pumps, boric acid transfer pumps, chiller pumps, regenerative HX, letdown HX, and other HXs, tanks, filters and demineralizers.
1.2.2.2.6 Reactor Coolant Pressure Boundary Leak Detection
- The Reactor Coolant Pressure Boundary Leak Detection System consists of temperature, level, humidity, and radioactivity sensors with associated instrumentation and alarms. Small leaks are detected by temperature and level changes of systems, increasing sump levels, and humidity and radioactivity concentration changes inside the Containment. Large leaks are detected by changes in reactor coolant inventory and changes in flow rates in process lines.
STPEGS UFSAR 1.2-4 Revision 1 8 1.2.2.3 Engineered Safety Features Systems. The following systems are used to directly mitigate the consequences of postulated accidents up to and including the Design Basis Accidents (DBAs) and are classified as Engineered Safety Features (ESF) Systems:
- 1. Containment Heat Removal System (CHRS)
- 2. Containment Isolation System (CIS)
- 4. Fuel Handling Building (FHB) Heating, Ventilating and Air Conditioning (HVAC) Exhaust Subsystem
- 5. Control Room (CR) Habitability Systems
- 6. Auxiliary Feedwater System (AFWS) 1.2.2.3.1 Reactor Containment
- This structure provides a virtually leaktight barrier to prevent escape of fission products to the environment in the unlikely event of a loss of coolant accident (LOCA).
The Reactor Containment is a post
-tensioned concrete cylinder with a steel liner plate, hemispherical top, and flat bottom. The overall dimensions of the Containment are:
Cylinder - Inside Diameter 150ft - Height 166 ft-3 in. - Wall thickness 4 ft - Liner thickness 3/8 in. Dome - Inside Radius 75 ft - Thickness 3 ft* - Liner thickness 3/8 in. Foundation
- Mat thickness 18 ft - Mat elevation (top)
(-) 13 ft-3 in. - Mat liner thickness 3/8 in.
- varies from 4 ft to 3 ft in transition zone
The Containment is designed to withstand the internal pressure and coincident temperature resulting from the mass and energy release of a LOCA.
1.2.2.3.2 Containment Heat Removal Systems
- Following the unlikely event of a LOCA, heat is removed from and pressure is reduced in the Containment by the Reactor Containment Fan Coolers (RCFCs) and the Containment Spray System (CSS). Following a LOCA, component STPEGS UFSAR 1.2-5 Revision 1 8 cooling water (CCW) is circulated through the RCFCs and borated water from the refueling water storage tank (RWST) is sprayed into the Containment atmosphere. Long
-term post-LOCA cooling and pressure reduction of the Containment is provided by switching the CSS suction to the Containment sump and by the RCFCs.
1.2.2.3.3 Containment Air Purification and Cleanup Systems
- Borated water followed by trisodium phosphate is used by the CSS to remove iodine from the Containment atmosphere following a LOCA.
1.2.2.3.4 Containment Isolation System
- Following a LOCA, the CIS provides the capability to isolate the various system lines penetrating the Containment and prevents the direct release of radioactivity to the environment.
1.2.2.3.5 Combustible Gas Control System
- Per 10CFR50.44, hydrogen recombiners are no longer required for design basis accidents.
1.2.2.3.6 Emergency Core Cooling System
- The ECCS injects borated water into the RCS following a LOCA to limit core damage, metal/water reaction, and fission product release, and to provide, in conjunction with the control rods, sufficient negative reactivity to assure safe shutdown of the reactor core.
Borated water is injected from the accumulators and the RWST. The ECCS also provides long
-term, post
-accident cooling of the core by recirculating borated water from the Containment sump to the core.
The system consists of three independent trains, each one capable of providing 100 percent of the required flow to the core in the unlikely event of a LOCA. Each train consists of one high
-head safety injection pump and one low
-head safety injection pump. Heat is removed from the system during recirculation by the residual heat removal HX (low
-head pump only). The piping and valving associated with each of the three subsystems are identical. In the event of a steam pipe rupture, the ECCS provides adequate shutdown capability.
1.2.2.3.7 Fuel Handling Building HVAC Exhaust Subsystem
- The FHB HVAC Exhaust Subsystem provides adequate filtration to remove radioiodines and particulates from the air above the spent fuel pool as well as the remainder of the FHB in the unlikely event of an accident.
1.2.2.3.8 Control Room Habitability Systems
- Habitability systems are provided to ensure that operating personnel can safely occupy the CR following a LOCA. Adequate shielding, air conditioning and filtering systems, health physics, and communications and domestic facilities are provided to allow residence for an extended period of time following the postulated accident.
1.2.2.3.9 Auxiliary Feedwater System
- The AFWS provides adequate cooling to the SGs in the event of a normal feedwater (FW) supply interruption. The system consists of four pumps. These pumps take suction from the auxiliary feedwater storage tank (AFST).
1.2.2.4 Engineered Safety Features Support Systems
.
1.2.2.4.1 Component Cooling Water System
- The Component Cooling Water System (CCWS) acts as an intermediate fluid barrier between the radioactive systems and the Essential STPEGS UFSAR 1.2-6 Revision 1 8 Cooling Water System (ECWS) to reduce the possibility of leakage of radioactivity from the plant to the environment.
The CCWS is designed to provide a continuous supply of cooling water to remove residual and sensible heat from the reactor during normal shutdown, to cool the letdown flow to the CVCS during power operation, to cool various ESF heat loads after a postulated LOCA, and to remove heat from various other plant components during normal operation.
1.2.2.4.2 Essential Cooling Water System
- The ECWS supplies cooling for those loads which are necessary for the safe shutdown of the reactor and to mitigate the consequences of postulated accidents. The ECWS also supplies cooling water to various systems during normal operation and shutdown.
Heat rejection to the ECWS during either normal operation, normal shutdown, or DBA conditions is accomplished by three redundant cooling water loops, each having its own pump and motor, piping, valves, and instrumentation. Each loop cools one set of diesel generator heat exchangers, CCW HX, one essential chiller and the CCW pump supplementary cooler.
The required cooling water is taken from the ECP (also ultimate heat sink [UHS]
).
1.2.2.4.3 Ultimate Heat Sink
- The ECP provides source of cooling water for the ECWS for safe plant shutdown for accident conditions, and is the normal heat sink for plant auxiliary heat loads for normal operating conditions and normal shutdown.
1.2.2.4.4 Standby Diesel Generator System
- Three standby diesel generators (DGs) are the onsite standby power sources feeding the Class 1E loads in the event that the offsite power sources become unavailable.
1.2.2.4.5 HVAC Systems
- Various HVAC systems, including the ECWS, EAB HVAC System, and other building or component cooling/ventilation systems, are provided to maintain the environment required for ESF components.
1.2.2.5 Reactor Control and Protection Systems
. The primary purposes of the Reactor Control and Protection Systems are to provide indication of automatic protection, to exercise proper control to ensure safe and proper reactor operation during steady
-state and transient power operations, and to provide initiating signals to mitigate the consequences of accident conditions.
1.2.2.5.1 Reactor Trip System
- The Reactor Trip System (RTS) automatically prevents operation of the reactor in an unsafe region by shutting down the reactor whenever preset limits are approached. The safe operating region is defined by several considerations, such as mechanical/hydraulic limitations on equipment and heat transfer phenomena. Therefore, the RTS keeps surveillance on process variables which are directly related to equipment mechanical limitations, such as pressure, pressurizer water level (to prevent water discharge through safety valves, and uncovering heaters), and also on variables which directly affect the heat transfer capability of the reactor, e.g., flow and reactor coolant temperatures. Still other parameters utilized in the RTS are calculated from various process variables. In any event, whenever a direct process or calculated variable exceeds a setpoint, the reactor will be shut down in order to protect against either STPEGS UFSAR 1.2-7 Revision 1 8 gross damage to fuel cladding or loss of system integrity which could lead to release of radioactive fission products into the Containment.
1.2.2.5.2 Engineered Safety Features Actuation System
- The ESF Actuation Systems are those instrumentation and control systems that are needed to actuate the equipment and systems listed in Sections 1.2.2.3 and 1.2.2.4.
1.2.2.5.3 Instrumentation and Control Power Supply System
- The Instrumentation and Control Power Supply System provides continuous, reliable dc or regulated single
-phase ac power to all instrumentation and control equipment required for plant safety.
1.2.2.5.4 Reactor Control System
- The Reactor Control System enables the nuclear plant to accept a step load increase or decrease of 10 percent and a ramp increase or decrease of 5 percent per minute within the load range of 15 percent to 100 percent without reactor trip, turbine bypass or pressurizer relief actuation, and is subject to possible xenon limitations.
The system also maintains reactor coolant average temperature (Tavg) within prescribed limits by creating the bank demand signals for moving groups of rod cluster control assemblies (RCCAs) during normal operation and operational transients. The Tavg control also supplies a signal to pressurizer water level control and steam dump control.
1.2.2.5.5 Rod Control System:
The Rod Control System provides for reactor power modulation by manual or automatic control of control rod banks in a preselected sequence and for manual operation of individual banks.
Control rod position is displayed in the control room, and alarms are provided to alert the operator if the required core reactivity shutdown margin is not available due to excessive control rod insertion or if control rod deviation exceeds preset limits.
1.2.2.5.6 Plant Control System Interlocks
- Interlocks are provided to prevent further withdrawal of the control banks when signal limits are approached that predict the approach of a departure from nucleate boiling ratio limit or kW/ft limit and to inhibit automatic turbine load change as required by the NSSS.
1.2.2.5.7 Pressurizer Pressure Control
- This system functions to maintain or restore the pressurizer pressure to the design pressure 35 psi (which is well within reactor trip and relief and safety valve actuation setpoint limits) following normal operational transients that induce pressure changes. It functions by control (manual or automatic) of heaters and spray in the pressurizer. It also provides steam relief by controlling the power operated relief valves.
1.2.2.5.8 Pressurizer Water Level Control
- This control system establishes, maintains and restores pressurizer water level within specified limits as a function of the average coolant temperature. Changes in level are caused by coolant density changes induced by loading, operational and unloading transients. Level changes are produced by means of charging flow control (manual or automatic) as well as by manual selection of letdown orifices. It maintains coolant level in the pressurizer within prescribed limits by actuating the charging and letdown system, thus providing control of the reactor coolant water inventory.
STPEGS UFSAR 1.2-8 Revision 1 8 1.2.2.5.9 Steam Generator Water Level Control
- This system establishes and maintains the SG water level within predetermined limits during normal operation and operating transients. It restores the SG water level to within predetermined limits at unit trip conditions, provided that FW isolation has not occurred and the FW pump turbine supplied with steam. Steam generator water inventory control to maintain a minimum heat sink for the RCS is manual or automatic through the use of the FW control valves.
1.2.2.5.10 Steam Dump Control
- This control system permits the nuclear plant to accept a 50 percent load rejection without incurring reactor trip or lifting a main steam (MS) safety valve. Steam is dumped to the condenser as necessary to accommodate excess power generation in the reactor during turbine load reduction transients.
This control system ensures that stored energy and residual heat are removed following a reactor trip to bring the plant to equilibrium no
-load conditions without actuation of the SG safety valves. It also maintains the plant at no
-load conditions and permits a manually controlled cooldown of the plant.
1.2.2.5.11 Incore Instrumentation
- Incore instrumentation provides information on the neutron flux distribution and the core outlet temperatures at selected core locations.
1.2.2.5.12 Qualified Display Processing System
- The Qualified Display Processing System (QDPS) is an integrated system designed to perform the following functions:
- 1. Data acquisition and qualified displays for post
-accident monitoring.
- 2. Safety-grade control and position indication, as applicable, of several safety
-related valves.
- 3. Data acquisition, display and control to address the separation requirements of the South Texas Project Electric Generating System (STPEGS) design approach to a CR or relay room.
- 4. SG water level compensation for the effect of temperature changes in the reference leg fluid.
The system functions are performed by several subsystems. These subsystems, though related, have sufficient independence such that the individual functions can be performed with maximum reliability and minimum unnecessary interactions between functions.
1.2.2.5.13 Emergency Response Facilities Data Acquisition and Display System
- This data acquisition system is described in Sections 1.2.2.14.1 and Sections 7.5.7.

-flow, 40-in. last-stage-blade, 1,800
-rpm machine. It is installed outdoors on a turbine pedestal. The turbine guaranteed rating is 1,311,838 kW at a backpressure of 3.5 in. Hg abs. and 0 STPEGS UFSAR 1.2-9 Revision 1 8 percent makeup. The rating of the electric generator is 1,504,800 kVA at 60 Hz and a 0.90 power factor.
1.2.2.6.2 Main Steam System
- The MS System transfers the steam from the outlet of the SGs to the turbine, where it is converted into mechanical energy that drives the electric generator. The steam is also used for various other services, such as shaft steam seals and turbine drives for main and auxiliary FW pumps.
Steam generator safety and power
-operated relief valves are provided to protect the SG and the MS System in the event of high steam pressure.
1.2.2.6.3 Condenser: The condenser is a three
-shell, single
-pass type located below the turbine. Cooling water from the MCR passes through the tubes with the condensing steam flowing outside the tubes. Condensate is collected in the hotwell where the condensate pumps take their suction and supply the FW system.
1.2.2.6.4 Condenser Air Removal System
- The Condenser Air Removal System removes air from the condenser. During operation, it removes noncondensible gases which are then discharged to the unit vent and monitored for radiation. The evacuation system consists of three 50-percent-capacity motor driven vacuum pumps which operate in parallel.
1.2.2.6.5 Turbine Gland Sealing System
- The Turbine Gland Sealing System is designed to prevent in leakage of air to the turbine or outleakage of steam along the turbine shaft.
The system provides steam for sealing the main turbine and SG feed pump turbine shafts. The MS System is the normal source of sealing steam. Auxiliary Steam (AS) may be used during normal shutdown. The leakoff steam and air mixture flows to the gland seal condenser, which is cooled by condensate. The condensed leakage is returned to the main condenser, and noncondensible gases are exhausted to the atmosphere.
1.2.2.6.6 Turbine Bypass System
- The Turbine Bypass System provides an artificial steam load in the Steam and Power Conversion Systems when necessary. The system is rated at 4 0-percent of plant design steam flow. This bypass flow allows the turbine to take a 50-percent load reduction without reactor trip or lifting of SG safety valves. The bypass steam is equally distributed to all condenser shells to prevent uneven turbine exhaust backpressures. The Turbine Bypass System is not required for any safety function, but it provides operational flexibility and minimizes steam relief to the atmosphere.
1.2.2.6.7 Condensate and Feedwater System
- The Condensate and FW Systems convey condensed steam from the condenser hotwells and the drains from the regenerative feedwater heating cycle to the SG while maintaining the water inventories throughout the cycle.
The condensate pumps take suction from the condenser hotwells and discharge through the FW heaters to the deaerator.
The low-pressure heater drip pumps take suction from the flash tanks that collect drains from the two lowest pressure FW heaters and pump the drips into the condensate heater.
STPEGS UFSAR 1.2-10 Revision 1 8 Condensate flows to and from the secondary makeup tank (SMT) to maintain the proper inventory of water in the secondary cycle.
Feedwater booster pumps draw deaerated water from the deaerator storage tank to provide ample net positive suction head (NPSH) to the feedwater pump suction.
The three steam
-driven FW pumps discharge through the highest pressure FW heater into the SGs.
A Condensate Polishing Demineralizer System is provided to remove dissolved and suspended solids from the condensate.
1.2.2.6.8 Steam Generator Blowdown System
- The SG blowdown system provides the means to continuously blowdown the SG to maintain the prescribed water chemistry in the SGs. It also removes the dissolved solids and corrosion products from the blowdown stream to make it suitable for reuse in the condenser hotwell.
1.2.2.7 Electrical Systems.
1.2.2.7.1 Utility Grid Description
- Four transmission service providers tie into the STPEGS switchyard: CenterPoint Energy, AEP Texas Central Company (TCC), City of Austin, and City Public Service Board of San Antonio. The combined electrical grids of the four systems presently consist of interconnected fossil
-fuel plants which serve approximately 51,354 square miles of area with an overlaid 345/138/69 kV transmission system.
1.2.2.7.2 Onsite Electrical System: The Onsite Electrical System of each unit consists of the unit auxiliary transformer, four 13.8 kV auxiliary busses, three 13.8 kV standby busses, five 4.16 kV auxiliary transformers, two normal 4.16 kV auxiliary busses, three ESF 4.16 kV auxiliary buses and three DGs. The three ESF 4.16 kV auxiliary busses feed the Class 1E ac power loads. The Class 1E 125 vdc power system consists four independent subsystems (channels).
Channels I and IV each consist of two inverters, one battery, and two battery chargers. Channels II and III each consist of one inverter, one battery, and two battery chargers.
The Onsite Electrical System is designed to supply the functional requirements of all auxiliary loads required for all modes of plant operation. Sufficient instrumentation and protective control devices are provided to ensure reliability and availability of the system.
1.2.2.7.3 Offsite Electrical System
- The Offsite Electrical System consists of two (345/13.8/13.8 kV) standby transformers, the 138 kV emergency transformer (138/13.8 kV), two main generators, two main power transformers (345/25 kV), the 345 kV lines connecting the main power transformers and the standby transformers to the switchyard, and the 345 kV switchyard, and the nine 345 kV transmission circuits from the STPEGS 345 kV switchyard to the interconnecting grids, and the 138 kV radial line out of TCC's Blessing Substation circuit to the 138 kV emergency transformer.
The transmission system provides reliable sources of offsite power for supplying plant auxiliary power systems for plant startup, shutdown or at any time that power is unavailable from the unit's STPEGS UFSAR 1.2-11 Revision 1 8 main generator. The normal power supply to unit balance
-of-plant (BOP) auxiliary loads is provided through the unit auxiliary transformer connected to the generator bus.
The unit auxiliary transformers can provide power from the main generator or from the 345 kV switchyard through the main transformers (with generator breakers open) to all that unit's BOP and ESF loads (Fig. 8.
2-3). The standby transformers are individually supplied by separate and independent overhead 345 kV ties from the 345 kV switchyard. These 345 kV ties to the standby transformers are connected to two separate 345 kV busses. Each transformer can provide offsite power to all ESF busses in both units and two 13.8 kV auxiliary busses.
1.2.2.8 Radioactive Waste Management Systems
. 1.2.2.8.1 Liquid Waste Processing System
- The Liquid Waste Processing System (LWPS) collects and processes potentially radioactive liquid wastes. The LWPS is designed to receive, segregate, process, recycle, and discharge liquid wastes. Provisions are made to sample and analyze fluids before they are discharged. The system design considers potential personnel radiation exposure and ensures that quantities of radioactive releases to the environment meet the requirements of Appendix I of 10CFR50 and are as low as is reasonably achievable (ALARA).
Under normal plant operation, release from the LWPS will be a small fraction of the concentration limits as defined in Appendix B of 10CFR20.
1.2.2.8.2 Gaseous Waste Processing System
- The Gaseous Waste Processing System (GWPS) removes and processes fission product gases from the RCS, CVCS, and other miscellaneous sources. The design objectives of the GWPS are two
-fold: first, to collect fission product gases from the various sources; and second, to process and control the release of gaseous radioactive effluents to the sit environs so that the total radiation exposure to offsite persons is ALARA and does not exceed applicable regulations.
1.2.2.8.3 Solid Waste Processing System
- The design objective of the Solid Waste Processing System is to provide a practicable means for collection, processing, packaging, temporary storage, and preparation for shipment of the solid radioactive wastes generated during operation of each unit.
1.2.2.8.4 Radiation Monitoring System
- The Radiation Monitoring System (RMS) is a group of independent radiation monitors used to measure the levels of radioactivity within various process streams, ventilation ducts, and plant general areas. The monitors are designed to provide information on the radiation levels to the plant main control room as well as locally at the monitors. The monitors initiate alarm signals when predetermined setpoints are exceeded and initiate various control functions as required when selected alarms are initiated. The RMS continuously records the levels of radiation in the various streams and areas to indicate trends of increasin g radiation so as to aid in achieving ALARA radioactivity releases and personnel exposures.
1.2.2.9 Cooling Water Systems
.
STPEGS UFSAR 1.2-12 Revision 1 8 1.2.2.9.1 Auxiliary Cooling Water System
- The Auxiliary Cooling Water System (ACWS) is used to service nonsafety
-related equipment in the turbine plant and nonsafety
-related HVAC chillers.

The following utilities currently own the South Texas Project Electric Generating Station (STPEGS) site, Units 1 and 2, and common station facilities:
NRG South Texas, LP City Public Service Board of San Antonio (CPS)
City of Austin (COA)
1.4.2 Applicant
The applicant was Houston Lighting & Power Company (HL&P), acting for itself and for CPS, COA, and Central Power and Light Company (CPL) pursuant to the South Texas Project Electric Generating System Participation Agreement between the four companies. HL&P was acting as project manager for the owners, responsible for the design, construction, and operation of STPEGS, Units 1 and 2.
HL&P had the responsibility of securing and maintaining the operating licenses for the two units. HL&P has been involved in a limited amount of the design for the two units, has reviewed the plant design, and had the initial overall responsibility of STPEGS.
On November 17, 1997 responsibility for the operation of the South Texas Project was transferred from HL&P to the STP Nuclear Operating Company (STPNOC). STPNOC is a Texas non
-profit corporation created, controlled and financed by the owners specifically for the purpose of operating STPEGS. This change was incorporated in the Unit 1 and Unit 2 Licenses via Amendments 93 and 80, respectively.
On August 31, 2002, HL&P (Reliant Energy) transferred its ownership interest in STPEGS and in STPNOC to Texas Genco, LP. This change was incorporated in the Unit 1 and Unit 2 Operating Licenses via Amendments 142 and 130, respectively.
On January 12, 2006, the NRC approved the transfer of ownership interest in STPEGS and in STP Nuclear Operating Company from Texas Genco, LP to NRG South Texas LP. This change was incorporated in the Unit 1 and Unit 2 Operating Licenses via Amendments 178 and 165, respectively.
American Electric Power Company, Inc. (AEP) is the parent company of CPL. Effective December 23, 2002, AEP sold the retail company portion of CPL to Centrica, and transferred the Central Power and Light/CPL names to Centrica as well. AEP renamed the remaining portions of CPL (generation and distribution interests) as "AEP Texas Central Company" (TCC). ). TCC sold its STP ownership interest to CPS and Texas Genco, LP on May 19, 2005.

CN-3 101 CN-3101 STPEGS UFSAR 1.5-1 Revision 131.5 REQUIREMENTS FOR FURTHER TECHNICAL INFORMATION Reference 1.5-1 presents descriptions of the safety-related research and development programs which are being carried out for, by, or in conjunction with Westinghouse Nuclear Energy Systems, and
which are applicable to Westinghouse Electric Corporation (Westinghouse) pressurized water
reactors (PWRs). For each program still in progress, the safety-related program is first introduced and then is followed, where appropriate, by background information. There is, then, a description of the program that relates program objectives to the problem and presents pertinent recent results. Finally, a backup position may be given for programs generally experimental rather than analytical which have not yet reached a stage where it is reasonably certain that the results confirm the expectation. The backup position is one that might be used if the results are unfavorable; it is not necessarily the only course that might be taken. The term "research and development", as used in the report, is the same as that used by the Nuclear Regulatory Commission (NRC) in Section 50.2 of its regulations, that is: (n) 'Research and development' means (1) theoretical analysis, exploration or experimentation; or (2) the extension of investigative findings and theories of a scientific nature into practical application for experimental and demonstration purposes including the experimental production and testing of models, devices, equipment, materials, and processes. The technical information generated by these research and development programs will be used to demonstrate the safety of the design and more sharply define margins of conservatism or will lead to design improvements. 1.5.1 Verification Tests (17 x 17 XLR Fuel Assembly) A comprehensive description of the 17 x 17 XLR Fuel Assembly is given in Section 4.2. 1.5.1.1 Rod Cluster Control Spider Tests. An evaluation of previously available test data was conducted to verify the fatigue life of the rod cluster control assembly (RCCA) spider in South Texas Units 1 and 2. This review of RCCA testing completed to date showed that further testing is not required to verify the South Texas spider design. The spider loads in the test data bound the expected loads in South Texas. 1.5.1.2 Grid Tests. The grid design of the XLR Fuel Assembly is similar to the 17 x 17 fuel assembly grid design. Verification tests of the structural adequacy of this grid design have been completed. Refer to Section 4.2 and Reference 1.5-2 for a discussion of these tests. 1.5.1.3 Fuel Assembly Structural Tests. The 17 x 17 XLR fuel assembly has been tested for mechanical strength, including internal damping, lateral and axial stiffness, and lateral and axial impact responses for both static and dynamic loading. These tests confirm the structural integrity of
the design.
STPEGS UFSAR 1.5-2 Revision 13 1.5.1.4 Prototype Assembly Tests. The purpose of these tests was to demonstrate that the 17 x 17 XLR fuel assembly design will perform as predicted. The tests, which included flow and system conditions covering those most likely to occur in a plant during normal operation, verified the adequacy of the design. 1.5.1.5 Guide Tube Tests. Verification tests of the structural adequacy of the guide tubes have been completed, and reported in WCAP-9596 (Ref. 1.5-7). 1.5.1.6 Single Rod Burst Test. Previously, single-rod burst tests (SRBTs) and multi-rod burst tests (MRBTs) were performed on 15 x 15 fuel assembly rods under conditions conservatively calculated to exist during a loss-of-coolant-accident (LOCA). The conclusions drawn from these tests were that fuel rods burst in a staggered manner to produce assembly average blockage at the peak axial location of 47 percent or less. Subsequently, the NRC determined that fuel rod burst and fuel assembly blockage should be predicted using models contained in NUREG-0630. These models have been incorporated into the Westinghouse Emergency Core Cooling System (ECCS) Evaluation Model (featuring BASH) used
herein (Ref. 1.5-9). 1.5.2 Lower Internals 1/7 Scale Model Internals Test Test Purpose and ParametersIn this series of tests, a 1/7-scale model of the 17 x 17 XLR internals will be employed to determine the vibration and flow forces on the internals.Flow distribution through the lower core support plate to the fuel assemblies will be verified, and the flow velocities at other areas within the vessel will be measured.
Facility These tests were conducted in the Westinghouse Test Engineering Laboratory H-Loop.
StatusThe 17 x 17 XLR internals 1/7 scale model test is completed and is reported in WCAP-9395 (proprietary) (Ref. 1.5-5). 1.5.3 Lower Internals Vibration Tests Test Purpose and Parameters See Section 3.9.2.3 and WCAP-10865 (Ref. 1.5-8).
1.5.4 LOCA Heat Transfer (17 x 17 XLR)
STPEGS UFSAR 1.5-3 Revision 13Extensive experimental programs have been performed with a simulated 17 x 17 assembly to determine its behavior under LOCA conditions. The 17 x 17 tests were conducted in the G-2 Loop Facility at the Westinghouse Forest Hills Laboratory. Results from the 17 x 17 programs were used together with data from 15 x 15 assembly test programs to validate the BART computer code (Ref. 1.5-4) models for predicting LOCA heat transfer. 1.5.5 Rapid Refueling Hardware Tests Selected tests have been conducted on components specifically designed for the Rapid Refueling System. These selected tests are limited to components which have a direct impact on safety. These tests are considered confirmatory (Ref. 1.5-6). 1.5.6 Prototype Roto-Lok Closure System Test Test Purpose and Parameters A full-size prototype roto-lok stud, vessel insert, closure nut, spherical washer, and associated hardware were tested to verify the design. Static loads were placed on this closure system to obtain shank, lug, and fillet stress. These stresses were compared to the analytical numbers obtained in the design to verify that proper assumptions were made for obtaining reactor vessel and stud sizes.
Fatigue tests were conducted to obtain stresses under simulated conditions of heatup, cool-down, and vessel opening and closing.
FacilityThese tests were conducted in a special test area set up at the Westinghouse Forest Hills test site.Following the completion of the test, the facilities were dismantled for storage.
StatusThe full-size prototype roto-lok closure tests were conducted and documented in WCAP-8447 (Ref.
1.5-6).1.5.7 Prototype Control Rod Drive Mechanism with Rod Holdout Device System Test Test Purpose and ParametersA magnetic jack mechanism with the rod holdout device will be tested to verify the safety and reliability of this system for holding rods withdrawn during refueling operations and for preventing this system from activating during power operation. Cyclic tests were performed to determine wear rates and characteristics. Static load tests were performed to determine load-carrying capabilities of the system.
Facility STPEGS UFSAR 1.5-4 Revision 13These tests on t he Rod Holdout System were performed in the control rod drive mechanism (CRDM) test facilities located at EMD, Cheswick, Pennsylvania, and in the D Loop Facility at the
Westinghouse Forest Hills Laboratory.
StatusThe CRDM rod holdout device test was completed in May 1978. Results of the test were satisfactory and documented in WCAP-9596 (Ref. 1.5-7). These tests are considered confirmatory. 1.5.8 Westinghouse Test Engineering Laboratory Facility The Test Engineering Laboratory at Forest Hills, Pennsylvania, has long been the major Westinghouse center for nuclear research and development. The Test Engineering Laboratory is totally involved with the design and implementation of facilities and programs to prove the reliability of Westinghouse PWR concepts and components. The Test Engineering Laboratory has full in-house capabilities to design and construct PWR loops for both hydraulic and heat transfer programs. Five general purpose hydraulic loops are also involved in the development of improved water reactor components, as well as the reliability testing of current and prototype PWR components. The Test Engineering Laboratory is a very flexible installation, one which will continue to expand and develop as future needs for its services arise. Its staff varies according to requirements. The Test Engineering Laboratory has the option of obtaining personnel from the entire corporation, depending upon the
need for specific skills, knowledge, and experience.
