The nuclear alliance executes a single, strategic vision to create a broader portfolio of solutions, expanding its capabilities for new reactor and service opportunities.

Related Record Related Record. Eractor 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.

The pools are sized to provide sufficient amounts of water to maintain the water at a level above the top of the nuclear fuel. Types of nuclear fission reactor.

First licence for ESBWR

Unsourced material may be challenged and removed. Archived from the original on It consists of large pools of water inside containment located above the reactor that are connected to the reactor pressure vessel. The program was a success however, because the design proved many of the passive safety technology developments that are being utilized in the ESBWR.

Retrieved 24 September GE stopped eswbr program because the power output of the SBWR was too small to generate the right economics for a new build project.

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.


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 level in the eshwr and remove decay heat from the reactor by transferring it outside containment.

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.

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 geactor increased power levels. The steam is condensed in the heat exchangers and the denser condensate then flows back down to the reactor to complete the cooling loop. The final safety evaluation report accepted by the NRC reports an overall core damage frequency of 1.

Get permanent URL for this record. The ESBWR’s technology represents the culmination of more than 55 years of experience designing, building and servicing advanced reactors globally. The PCCS consists of a set of heat exchangers located in the upper portion of the reactor building.

The company has not committed to building the new plant but says it intends to keep the option open for long-term planning purposes. 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.
