According to GEH, the ESBWR is the world’s safest approved nuclear reactor design based on core damage frequency. The reactor has. generation nuclear reactor, commonly referred to as the “ESBWR”. No other use, direct or indirect, of the document or the information it contains is authorized;. The COL references GE Hitachi Nuclear Energy’s (GEH) Economic Simplified Boiling Water Reactor (ESBWR), which received design.

Key global commercial projects include: Please provide a name for this query: NRC’s decision concludes a technical, safety and environmental review process that began when DTE submitted the COL application for the proposed plant in September There are no circulation pumps or associated piping, power supplies, heat exchangers, instrumentation, or controls needed for these systems.

Second, fewer demands on plant operators and safety systems reduce plant operating staff while still providing direct improvements in accident and transient response. ESBWR safety systems are designed to operate normally in the event of station blackout, which prevented proper functioning of the emergency core cooling systems at the Fukushima Daiichi Nuclear Power Plant.

The steam is condensed in the heat exchangers and the denser condensate then flows back down to the reactor to complete the cooling loop. In case of an accident, the ESBWR can remain in a safe, stable state for 72 hours without any operator action or even electrical power. Looks like Javascript is disabled on your browser.

If the water level inside the reactor pressure vessel drops to a predetermined level, due to the loss of water inventory, the reactor is depressurized and the GDCS is initiated.

Through design simplification and standardization, ESBWR offers improved safety, increased reliability, and ease of operation. According to GEH, that project is expected to receive a licence in GE stopped this program because the power output of the SBWR was too small to generate the right economics for a new build project.


Reactor coolant is cycled through this flow path to provide continuous cooling and to add water to the reactor core. Based on core damage frequency, the industry standard measure of safety, the ESBWR is the world’s safest approved nuclear reactor design. Reacyor from the original pdf on This article needs additional citations for reactoe.

The ICS system is a closed loop system that connects the reactor pressure vessel to a heat exchanger located in the upper elevation of rractor reactor building. March Learn how and when to remove this template message. The company also said that the NRC certification has paved the way for it to be built in other locations around the world, and pointed to Brazil, India, Poland, Saudi Arabia, South Africa, Sweden and Vietnam as potential project locations.

The combination of these features allows the pool to be refilled easily with low pressure water sources and installed piping. New build Plant licensing USA.

Articles needing additional references from March All articles needing additional references All articles with dead external links Articles with dead external links from September Articles with permanently dead external links. In cases where the reactor coolant pressure boundary does not remain intact and water inventory in the core is being lost, the Passive Containment Cooling System PCCS and Gravity Driven Reacgor System GDCS work in concert to maintain the water level reactod the core and remove decay heat from the reactor by transferring it outside containment.

It consists of large pools of water inside containment located above the reactor that are esbar to the reactor pressure vessel. According to GEH, the ESBWR also offers the lowest projected operating, maintenance and staffing costs in the nuclear industry on a per-kilowatt basis.

Sign Up Sign Up. The ESBWR employs advanced, true passive safety systems and a simplified design utilizing natural circulation. The company has not committed to building the new plant but says it intends to keep the option open for long-term planning purposes. The NRC granted approval in September To find out more check our cookies and privacy policy. Finally, reductions in building volumes and required manufactured components shorten the length of time needed for ESBWR construction, resulting in improved financial returns for plant owners.


Archived from the original on The regulator completed its environmental review and issued the final environmental impact statement for the plant in January The final safety evaluation report accepted by the NRC reports an overall core damage frequency of 1. The passive safety systems in an ESBWR operate without using any pumps, which creates increased design safety, integrity, and reliability, while simultaneously reducing overall reactor cost.

Types of nuclear fission reactor. This page was last edited on 13 Septemberat Please help improve this article by adding citations to reliable sources.

The reactor core is shorter than in conventional BWR plants to reduce the pressure drop over the fuel, thereby enabling natural circulation. The alliance offers customers around the world the technological leadership required to effectively enhance reactor performance, power output and safety. The COL application was submitted before the Fukushima Daiichi accident ofand conditions that the NRC has imposed on the licence address the regulator’s post-Fukushima requirements for mitigation strategies, spent fuel pool instrumentation, and emergency preparedness plans and procedures.

On June 7,the NRC completed its public comment period. Retrieved from ” https: From Wikipedia, the free encyclopedia. First, fewer active components in particular, active safety systems reduce the maintenance and online surveillance requirements, thereby reducing operational exposure and dose rates.

It also uses natural circulation to drive coolant flow within the reactor pressure vessel RPV ; this results in fewer systems to maintain, and precludes significant BWR casualties such reacror recirculation line breaks. An Evolutionary Reactor Design.
