US-APWR Design
As a result of extensive verification and qualification testing, we have developed an Advanced Pressurized Water Reactor (APWR) design that is more efficient with greater output than any previous power plant. This design has been slightly modified to satisfy U.S. and international utility requirements as the US-APWR, and it will become the design that we sell around the globe. The US-APWR satisfies our customers’ requirements with the best performance for safety, economy, operation and maintenance.
The main specifications of the US-APWR are:
| Electric Power |
1,700 MWe |
| Core Thermal Power |
4,451 MWt |
| Reactor Fuel Assemblies |
257 |
| Reactor Fuel |
Advanced 17x17, 14 ft. |
| Active Core Length |
4.2 meters |
| Coolant System Loops |
4 |
| Coolant Flow |
2.75x104 m3/h/loop |
| Coolant Pressure |
15.5 MPa |
| Steam Generator Type |
90TT-1 |
| Number of Steam Generators |
4 |
| Reactor Coolant Pump Type |
100A |
| Number of Reactor Coolant Pumps |
4 |
| Reactor Coolant Pump Motor Output |
6,000 kW |
Features of the US-APWR include:
Enhanced Safety:
- A four-train safety system for enhanced redundancy.
- An advanced accumulator.
- An in-containment refueling water storage pit.
Enhanced Reliability
- A steam generator with high corrosion resistance.
- A neutron reflector with improved internals.
- A 90% reduction in plant shutdowns compared to other four-loop PRWs.
Attractive Economy
- A large core with a thermal efficiency of 39%.
- Building volume per MWe that is four-fifths that of other four-loop PWRs.
More Environment Friendly
- A 28% reduction in spent fuel assemblies per MWh compared to other four-loop PWRs.
- Reduced occupational radiation exposure.
- Capacity to use mixed oxide (MOX) fuels made from reprocessed nuclear fuel waste.
