The ESBWR is designed to meet the needs of nuclear power plant owners today and into the future, with a year design life.

The NRC granted approval in September The pool is vented to the atmosphere and is located outside of the reactir. Get permanent URL for this record. Retrieved from ” https: The alliance offers customers around the world the technological leadership required to effectively enhance reactor performance, power output and safety.

Please help improve this article by adding citations to reliable sources.

First, fewer active components in particular, active safety systems reduce the maintenance and online surveillance requirements, thereby reducing operational exposure and dose rates. We use cookies to provide the reactlr experience for you.

Types of nuclear fission reactor. Key global commercial projects include: The ESBWR employs advanced, true passive safety systems and a simplified design utilizing natural circulation.

Economic Simplified Boiling Water Reactor – Wikipedia

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.

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. 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 Cooling System GDCS work in concert to maintain the water rsbwr in the core and remove decay heat from the reactor by transferring it outside containment.


The steam from the reactor rises through the containment to the PCCS heat exchangers where the steam is condensed. Second, fewer demands on plant operators and safety systems rreactor plant operating staff while still providing direct improvements in accident and transient response.

Nuclear fusion reactors List of nuclear reactors Nuclear technology Nuclear accidents. New build Plant licensing USA. These attributes result in the ability of the reactor to cool itself for more than ssbwr days without operator intervention or AC power on or off site.

Sign Up Sign Up. Another condition requires monitoring and analysis of the plant’s steam dryer during initial start-up, in line with NRC’s esbw requirements for existing BWRs operating at increased power levels.

Retrieved 24 September In addition to its best-in-class safety, the ESBWR includes a modular design for ease of construction, increased fuel efficiency and the lowest projected operating, maintenance and staffing costs per megawatt hour in the reacotr.

As reacotr result, operating and maintenance staff requirements are reduced; low-level waste generation is reduced; dose rates are reduced; operational reliability is improved; and plant safety and security are improved. From Wikipedia, the free encyclopedia. Both the ICS and Ewbwr heat reactpr are submerged in a pool of water large enough to provide 72 hours of reactor decay heat removal capability. The licence, which NRC says will be issued promptly, will authorize DTE Energy to build and operate the unit at a site exbwr to its operating Fermi 2 boiling water reactor on the shores of Lake Erie.

Javascript must be enabled for narrowing. The reactor core is shorter than in conventional BWR plants to reduce the pressure drop over the fuel, thereby enabling natural circulation.

Yet compared to current nuclear power plants, the ESBWR requires only a fraction of traditional plant operating and maintenance staff, offers faster construction and lower costs of construction, while also reducing operational costs.

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. Design certification also paves the way for the ESBWR to be built in other locations around the globe. This article needs additional citations for verification. The company has not committed to building the new plant but says it intends to keep esnwr option open for long-term planning purposes.


Please provide a name for this query: According to GEH, the ESBWR also offers the lowest projected operating, maintenance and staffing costs in the nuclear industry on reactlr per-kilowatt basis.

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 pipes facilitate cooling above and below the molten core with water.

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 reacyor into the containment in the form of steam. Below the vessel, there is a piping structure that allows for cooling of the core during any very severe accident. An Evolutionary Reactor Design. Archived from the original pdf on The program was a success however, because the design proved many of the passive safety technology developments that are being utilized in the ESBWR.

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

Retrieved 24 January It consists of large pools of water inside containment located above the reactor that are connected to the reactor eabwr vessel. Organic nuclear reactor Aircraft Reactor Experiment. The pools are sized to provide sufficient amounts of water to maintain the water at a level above the top of the nuclear fuel.
