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.

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.

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 eabwr recirculation line breaks. Key global commercial projects include: From Wikipedia, the free encyclopedia. We use cookies to provide the best experience for you. The final safety evaluation report accepted by the NRC reports an overall core damage frequency of 1.

Standard Search Advanced Search. New build Plant licensing USA. The licence, which NRC says will be issued promptly, will authorize DTE Energy to build and operate the unit at a site adjacent to its operating Fermi 2 boiling water reactor on the shores of Lake Erie. Archived from the original pdf on After the reactor has been depressurized, the decay heat is transferred to the containment as water inside the reactor boils and exits the reactor pressure vessel into the containment in the form of steam.

Economic Simplified Boiling Water Reactor – Wikipedia

The condensate then drains from the PCCS heat exchangers back to the GDCS esbar where it completes the cycle and drains back to the reactor pressure vessel.


Design certification also paves the way for the ESBWR to be built in other locations around the globe. Based on core damage frequency, the industry standard measure of safety, the ESBWR is the world’s safest approved nuclear reactor design. First, fewer active components in particular, active safety systems reduce the maintenance and online surveillance requirements, thereby reducing operational exposure and dose rates.

GE Hitachi’s ESBWR Receives NRC Design Certification Approval

In addition to its best-in-class safety, the ESBWR includes a modular reactoor for ease of construction, increased fuel efficiency and the lowest projected operating, maintenance and staffing costs per megawatt hour in the industry. Please help improve this article by adding citations to reliable sources.

Views Read Edit View history. Another condition requires monitoring and analysis of the plant’s steam dryer during initial start-up, in line with NRC’s current requirements for existing BWRs rsbwr at increased power levels.

GE Hitachi’s ESBWR Nuclear Reactor Gains Some Industry Support

While the company has not made a decision to build the new unit, we consider North Anna 3 as an important part of our strategy to maintain a diverse supply of electrical generation for our customers and at the same time lower our overall carbon footprint in Virginia. Nuclear fusion reactors List of nuclear reactors Nuclear technology Nuclear accidents.

It consists of large reachor of water inside containment located above the reactor that are connected to the reactor pressure reacto. Sign Up Sign Up. Below the vessel, there is a piping structure that allows for cooling of the core during any very severe accident.

GE stopped this program because the power output of the SBWR was too small to generate the right economics for a new build project. Close Go to Workspace. 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. These systems utilize natural circulation based on simple laws of physics to transfer the decay heat outside containment while maintaining water levels inside the reactor, keeping the nuclear fuel submerged in water and adequately cooled. Retrieved 24 September By using this site, you agree to the Esbbwr of Use and Privacy Policy.

The program was a success however, because the design proved many of the passive safety technology developments that are being utilized in the ESBWR. On June 7,the NRC completed its public comment period.

The pool is vented to the atmosphere and is located esbrw of the containment. This page was last edited on 13 Septemberat Javascript must be enabled for narrowing.

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. According to GEH, that project is expected to receive a licence in Get permanent URL for this record.

Steam leaves the reactor through the ICS piping and travels to the ICS heat exchangers which are submerged in a large pool. Organic nuclear reactor Aircraft Reactor Experiment.
