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.

Please provide a name for this query: In events where the reactor coolant pressure boundary reactot intact, the Isolation Condenser System ICS is used to remove decay heat from the reactor and transfer it outside containment.
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 operating at increased power levels. New build Plant licensing USA. While the company has not made a reactod 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.
According to GEH, that project is expected to receive a licence in 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.
Retrieved from ” https: Sign Up Sign Up. The ESBWR’s technology represents the culmination of more than 55 years of experience designing, building and servicing advanced reactors globally. Retrieved 24 September 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.

Close Go to Workspace. 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. 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.
Types of nuclear fission reactor. There are no circulation pumps or associated piping, power supplies, heat exchangers, instrumentation, or controls needed for these systems.
First licence for ESBWR – World Nuclear News
These attributes result in the ability of the reactor to cool itself for more than seven days without operator intervention or AC power on or off site. As a 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. The NRC granted approval in September Based on core damage frequency, the industry standard measure of safety, the ESBWR is the world’s safest approved nuclear reactor design.
March Learn how and when to remove this template message. First, fewer active components in particular, active safety systems reduce the maintenance and online surveillance requirements, thereby reducing operational exposure and dose rates.
United States Department of Energy. Our Privacy and Cookies Policy. The ICS system is a closed loop esber that connects the reactor pressure vessel to a heat exchanger located in the upper elevation of the reactor building. The licence, which NRC says will be issued promptly, will ewbwr 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.
Below the vessel, there is a piping structure that allows for cooling of the core during any very severe accident. The steam from the reactor rises through the containment to the PCCS heat exchangers where the steam is condensed. Views Read Edit View history. NRC’s decision concludes a technical, safety and environmental review process that began when Reactir submitted the COL application for the proposed plant in September Through design simplification and standardization, ESBWR offers improved safety, increased reliability, and ease of operation.
The final safety evaluation report accepted by the NRC reports an overall core damage frequency of 1.
Design certification also paves the way for the ESBWR to be built in recator locations around the globe. GE stopped this program because the power output of the SBWR was too small to generate the right economics for a new build project.

Archived from the original pdf on 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. Unsourced material may be challenged and removed. The combination of these features allows the pool to be refilled easily with low pressure water sources and installed piping.
Retrieved 24 January Reference Number Reference Number. 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.
