The South Texas nuclear power plant (also known as the South Texas Project (STP) ) with two reactor blocks is located southwest of Bay City in the south of the state of Texas in the USA . The owners are NRG South Texas (44%), a subsidiary of NRG Energy , and the cities of San Antonio (40%) and Austin (16%). The operator is the STP Nuclear Operating Company (STPNOC). The nuclear power plant is located on 49 km 2 on the Colorado River about 145 km southwest of Houston. It was the first nuclear power plant in Texas.
The reactors
The reactors in the South Texas nuclear power plant are two identical pressurized water reactors with a net electrical output of 1280 MW and a gross output of 1354 MW. The South Texas NPP is unique in its design of systems for the safety of the reactors. Each unit has three, instead of the usual two, completely independent Emergency Core Cooling Systems and the associated systems.
history
On December 6, 1971, Houston Lighting & Power Co. (HL & P) presented the City of Austin, the City of San Antonio and Central Power and Light Co. (CPL) with a feasibility study for the construction of a joint subsidiary of nuclear power plants. The original cost estimate for the power plant was $ 974 million.
Until mid-1973 the location of the power plant in Bay City was planned, but then the decision was made to build the power plant on a different site.
An application for planning permission for the facility was filed with the United States Atomic Energy Commission in May 1974. The Nuclear Regulatory Commission granted approval on December 22, 1975. Construction began on both blocks on December 22, 1975. By 1981, the South Texas Project was four years behind schedule and had significant cost overruns. Brown and Root revised the schedule for completion by June 1989 and the cost estimate to $ 4.4-4.8 billion.
The first block was synchronized with the power grid for the first time on March 30, 1988 and went into commercial power operation on August 25, 1988. Unit 2 was first synchronized with the power grid on April 11, 1989 and went into commercial operation on June 19, 1989.
In 2007, South Texas-2 was the world's highest annual nuclear reactor . Both blocks were previously among the top five several times.
In December 2016 it became known that South Texas was also affected by the Creusot Forge scandal over falsified certificates. Parts of the steam generator come from the polluted Areva daughter.
The future of the power plant
On June 19, 2006, NRG Energy presented a plan to build two ABWR reactors, each with a capacity of 1,358 MWe, on the site of the South Texas nuclear power plant.
On September 24, 2007, the operator submitted a complete application to the Nuclear Regulatory Commission to build two General Electric ABWRs on the site of the nuclear power plant. The proposed expansion of the STP would have an additional 2700 MW electrical output, so the power plant could have had about twice the installed capacity of today if the new buildings had been completed before the first two blocks were shut down. On April 19, 2011, NRG announced that it would end the new building project because the project partner Tepco was no longer available for South Texas due to the explosions in Fukushima .
The shutdown of the existing blocks is planned for 2027 (block 1) and 2028 (block 2).
Data of the reactor blocks
The South Texas nuclear power plant has a total of two blocks :
| Reactor block | Reactor type | net power |
gross power |
start of building | Network synchronization |
Commercialization of essential operation |
switching off processing |
|---|---|---|---|---|---|---|---|
| South Texas-1 | Pressurized water reactor | 1280 MW | 1354 MW | 12/22/1975 | 03/30/1988 | 08/25/1988 | (Planned for 2027) |
| South Texas-2 | Pressurized water reactor | 1280 MW | 1354 MW | 12/22/1975 | 04/11/1989 | 06/19/1989 | (Planned for 2028) |
