What factors must be considered while selecting materials for various reactor components?
The major factors considered in the selection of materials include operating conditions, availability of design data in nuclear codes, ease of fabrication, international experience and cost.
What metal would you choose to cool a fast breeder reactor?
sodium
For fast breeders using a liquid metal cooling system, sodium is the selected coolant since it can remove heat effectively from the compact reactor core and remains in the liquid state over a fairly broad temperature range.
What is the fuel used in Kalpakkam fast breeder test reactor?
KAMINI, the research facility at Kalpakkam which uses uranium-233 (extracted from irradiated thorium) fuel is a pioneering endeavour towards thorium utilization. The reactor was operated upto 30kW and used for irradiation of specimens for experimental/forensic purposes.
Which coolant is used for fast breeder reactor?
Liquid Sodium
So the correct answer is ‘ Liquid Sodium’.
What is the material of a reactor?
As mentioned, the very first reactor (CP-1) used wood as the structural material. However, today the nuclear structural materials are steel and concrete. The nuclear-fueled core is contained inside a steel vessel which has steel core support plates, top and bottom, upon which the core is held in place.
What materials are reactors made from?
Reactor materials include nuclear fuels (mainly uranium, but also plutonium and thorium), the clad- ding in which the fuel is contained and pipes and ves- sels in which coolants circulate (a large variety of steel, aluminium, zirconium and other alloys), mod- erators (graphite, beryllium, etc.), shielding (con- crete …
What does liquid metal fast breeder reactor Lmfbr mean?
A liquid metal fast breeder reactor (LMFBR) is a nuclear reactor capable of producing more fissile product than it takes in. Breeders exhibit remarkable fuel economy compared to light water reactors.
Which moderator used in fast breeder test reactor Fbtr?
No moderator is used in the breeder reactor since fast neutrons are more efficient in transmuting U-238 to Pu-239. Heavy water is used as a coolant to slow down the neutrons.
Which element is used in nuclear reactor for fuel?
uranium dioxide
A nuclear fuel element typically consists of a tube containing cylindrical uranium dioxide fuel pellets. In the reactor, heat is generated throughout the pellets and is conducted through the cladding tube to the surrounding coolant.
Why prototype fast breeder reactor?
India’s energy requirements are large and only nuclear energy produced through fast breeder reactors can meet a significant part of the requirements. The Prototype Fast Breeder Reactor has been designed based on FBTR experience. The design is validated by large amount of R&D carried out in various disciplines.
What is the PFBR reactor?
The PFBR is a 500 MWe, sodium cooled, pool type, mixed oxide (MOX) fuelled reactor having two secondary loops. The reactor is located at Kalpakkam, close to the 2 × 220 MWe PHWR units of the Madras Atomic Power Station (MAPS).
Who is responsible for the establishment of Fast Breeder technology in India?
Indira Gandhi Centre for Atomic Research, Kalpakkam is responsible for the establishment of fast breeder technology in the country. The commissioning of a 40 MWt/13 MWe Fast Breeder Test Reactor (FBTR) at Kalpakkam in 1985 marked the beginning of a FBR programme in India.
What is the core configuration of a nuclear reactor?
Fig. 1 shows the core configuration. A homogenous core concept with two fissile enrichment zones of 21/28% PuO 2 is adopted for power flattening. The active core where most of the nuclear heat is generated consists of 181 fuel subassemblies. Each fuel subassembly contains 217 helium bonded pins of 6. 6 mm diameter.
