The advanced boiling water reactor (ABWR) is a Generation III boiling water reactor. The ABWR is currently offered by GE Hitachi Nuclear Energy (GEH) and Toshiba.

The main feature of ABWR RRS is to adopt reactor internal pumps (PIRs), which eliminates conventional external loops consisting of the external recirculation pumps, large diameter pipes and internal jet pumps.

2024年1月1日 · Advanced boiling water reactors (ABWRs) represent a notable advancement in ligh water nuclear reactor technology. Developed collaboratively by General Electric and Hitachi, these reactors prioritize safety, efficiency, and sustainability.

The reactor feed pumps discharge through the high pressure feedwater heaters to the reactor. Major S&PC System design features are summarized in Table 10.1-1. The system main conceptual features are illustrated on Figure 10.1-1, assuming a triple pressure condenser.

piping or jet pump is required. The elimination of the external recirculation piping is particularly significant, as it provides a wide space inside the primary containment vessel and remov

2009年4月28日 · Hitachi has developed two mid-sized ABWRs (ABWR-600 and ABWR-900) to provide nuclear power plants that can respond flexibly to these requirements and to provide a distributed power source for regions where electricity demand or …

ABWR, which is the only Generation III+ reactor operating in the world, has achieved an incomparable level of safety with additional facilities for safety enhancement as well as plant layout designs to mitigate site specific external hazards.

2009年6月1日 · This work developed an advanced boiling water reactor (ABWR) feedwater pump and controller model, which was incorporated into Personal Computer Transient Analyzer (PCTran)-ABWR, a nuclear power plant simulation code. The feedwater pump model includes three turbine-driven feedwater pumps and one motor-driven feedwater pump.

ABWR采用10台 内置泵替代原先的喷射泵，省去了外部再循环回 路。 这种一体化主回路设计，使得堆芯顶部以下 没有大口径管道贯穿压力壳，减少了大破口失水 事故（LOCA）发生的可能性并减轻了事故的后 果。
