Is the Natrium reactor a breeder?
Given the reactor’s closed fuel cycle and generation of plutonium, a fissile fuel, the reactor can also be used as a breeder to regenerate fuel. This process requires additional recycling processes to ensure that the fuel is properly developed and qualified for use.

Is the Natrium reactor a breeder?
Given the reactor’s closed fuel cycle and generation of plutonium, a fissile fuel, the reactor can also be used as a breeder to regenerate fuel. This process requires additional recycling processes to ensure that the fuel is properly developed and qualified for use.
What is the coolant in EBR II?
sodium coolant
The clean-up process for EBR-II includes the removal and processing of the sodium coolant, cleaning of the EBR-II sodium systems, removal and passivating of other chemical hazards and placing the deactivated components and structure in a safe condition.
Who has the most advanced nuclear power plants?
The most developed Gen IV reactor design, the sodium fast reactor, has received the greatest share of funding over the years with a number of demonstration facilities operated, as well as two commercial reactors, operating in Russia. One of these has been in commercial operation since 1981.
What are two problems with liquid sodium cooled reactors?
Disadvantages. A disadvantage of sodium is its chemical reactivity, which requires special precautions to prevent and suppress fires. If sodium comes into contact with water it reacts to produce sodium hydroxide and hydrogen, and the hydrogen burns in contact with air.
Do Natrium reactors produce waste?
In mid-February, Gates told 60 Minutes correspondent Anderson Cooper that the Natrium reactor will produce less nuclear waste and be safer than a conventional light-water reactor.
What do breeder reactors produce?
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes.
How many breeder reactors are there?
two
Types. There are two categories of breeder reactors, based on the speed of the neutrons. Fast breeder reactors which use uranium-238 as fuel and thermal breeder reactors which use thorium-232 as fuel.
What is the safest nuclear power plant?
Molten-salt reactors
Molten-salt reactors are considered to be relatively safe because the fuel is already dissolved in liquid and they operate at lower pressures than do conventional nuclear reactors, which reduces the risk of explosive meltdowns.
What is the most efficient nuclear power plant?
The Beloyarsk Nuclear Plant is the only commercially operating fast breeder reactor in the world. Developed over more than 20 years, it started producing power since October 2016. The reactor produces over 800 MW of power. Fast breeder reactors produce more fuel than they consume.
What does EBR II stand for?
Experimental Breeder Reactor-II ( EBR-II) is a sodium-cooled fast reactor designed, built and operated by Argonne National Laboratory at the National Reactor Testing Station in Idaho. It was shut down in 1994. Custody of the reactor was transferred to Idaho National Laboratory after its founding in 2005.
What was the replacement for EBR 1?
EBR-I was deactivated by Argonne in 1964 and replaced with a new reactor, Experimental Breeder Reactor II . It was declared a National Historic Landmark in 1965 with its dedication ceremony held on August 25, 1966, led by President Lyndon Johnson and Glenn T. Seaborg.
What was the purpose of the EBR II test reactor?
Testing of the original breeder cycle ran until 1969, after which time the reactor was used to test concepts for the Integral Fast Reactor concept. In this role, the high-energy neutron environment of the EBR-II core was used for testing fuels and materials for future, larger, liquid metal reactors.
How much did it cost to build EBR 2?
Initial operations began in July 1964 and it achieved criticality in 1965 at a total cost of more than US$32 million (US$260 million in 2019 dollars). The original emphasis in the design and operation of EBR-II was to demonstrate a complete breeder-reactor power plant with on-site reprocessing of solid metallic fuel.
