The Economic Simplified Boiling Water Reactor (ESBWR) is a passively safe generation III+ reactor design derived from its predecessor, the Simplified Boiling Water Reactor (SBWR) and from the Advanced Boiling Water Reactor (ABWR). All are designs by GE Hitachi Nuclear Energy (GEH), and are based on previous Boiling Water Reactor designs.

2025年2月25日 · The ESBWR, designed by GE-Hitachi Nuclear Energy (GEH), is a single-cycle, boiling-water reactor (BWR), with a rated power of 4,500-MWt. The containment vessel is a cylindrical steel-lined reinforced concrete structure integrated with the reactor building.

Certified by the US Nuclear Regulatory Commission (NRC) in 2014, the ESBWR is the world’s safest light water reactor. It has the lowest core damage frequency (industry standard measure of safety) of any Generation III or III+ reactor and can safely cool itself with no AC electrical power or human action for more than seven days.

GEH’s Generation III+ reactor, the Economic Simplified Boiling Water Reactor (ESBWR) was certified by the U.S. Nuclear Regulatory Commission in 2014. GEH’s portfolio of modular reactors offer the safest and most efficient nuclear energy generation capability available.

GE Hitachi Nuclear Energy’s (GEH) next evolution of advanced Boiling Water Reactor (BWR) technology is the ESBWR. This simplified design provides improved safety, excellent economics; better plant security, a broad seismic design envelope, and operational flexibility that increases plant availability. long line of proven GEH BWR reactors.

2006年1月3日 · By harnessing these design concepts and testing results from the origi-nal SBWR and construction and operating experience from the Advanced Boiling Wa-ter Reactor (ABWR), the ESBWR design team has produced a simplified reactor with a standardized design and first-rate eco-nomics (see Table I).

2010年11月1日 · Two examples of these new reactor designs are GE Hitachi’s (GEH’s) Advanced Boiling Water Reactor (ABWR) and its later incarnation, the Economic Simplified Boiling Water Reactor (ESBWR, Figure...

2021年3月9日 · A 4,500- MWt nuclear reactor design, which has passive safety features and uses natural circulation (with no recirculation pumps or associated piping) for normal operation. GE-Hitachi Nuclear Energy (GEH) submitted an application for final design approval and standard design certification for the ESBWR on August 24, 2005.

The ESBWR, which is designed by GE Hitachi, is a generation III+ reactor that utilizes complete passive features and natural circulation principles for accident preventions and mitigations. The ESBWR is rated at 1560 MWe.
