breeder reactor has a conversion ratio of

‘This is because advanced converter reactors are optimised to achieve high conversion ratios and, in the case of heavy water moderated variants, low fissile inventories.’ ‘The material has a proven use in breeder and converter reactor systems.’ This will help us to improve better. (Assume that the reactor consists of pure fuel and that no neutrons escape from it.) b. By sizing a chemical reactor we mean we're either detering the reactor volume to achieve a given conversion or determine the conversion that can be achieved in a given reactor type and size. Ans: b. What is the maximum conversion ratio that could be achieved in principle with each fuel? Breeder reactor has a conversion ratio of _____. Given -r A as a function of conversion,-r A =f(X), one can size any type of reactor. MEDIUM. A. unity. A breeding ratio of greater than unity implies that for every fission reaction, more than one fissile atom can be generated, and the fuel can be bred from non-fissile material. Breeder reactor can maximize production of new fuel. C. less than unity. Uranium Breeding and Fast Breeders Here we will assume that we will be given -r A = f(X) and F A0.In chapter 3 we show how to find -r A = f(X).. This required a high level of energy density in the core, a fast neutron spectrum and a large proportion of fuel. D. zero. Consider that breeder reactors are to be built using 2 3U (obtained from 23 Th) and 239Pu, respectively. Boiling water reactor employs (a) boiler (b) direct cycle of coolant system (c) double circuit system of coolant cycle (d) multi pass system (e) single circuit system. Nuclear reactors are being developed to make use of this to breed fissile material from relatively much more abundant materials [6]. In the liquid-metal, fast-breeder reactor , the target breeding ratio is 1.4 but the results achieved have been about 1.2 . Ans: b. In a breeder reactor, the conversion ratio is higher than 1. 3. breeder reactors produce useful energy during operations, just as conventional "burners" using up uranium 235 do, by fission in a sustained chain reaction within the reactor core. However, at the very first stage, it became obvious that breeder reactors with a breeding ratio of 1.3–1.5 were needed. Breeder reactor has a conve... general knowledge. France has made the largest implementation of breeder reactors with its large Super-Phenix reactor and an intermediate scale reactor (BN-600) on the Caspian Sea for electric power and desalinization. toppr. Pressurized heavy water reactors running on natural uranium have a conversion ratio of 0.8. Upvote(4) How satisfied are you with the answer? B. more than unity. A converter, with a conversion ratio near 1, offers a balance of TRU production and consumption. In the breeding of plutonium fuel in breeder reactors, an important concept is the breeding ratio, the amount of fissile plutonium-239 produced compared to the amount of fissionable fuel (like U-235) used to produced it. This mode results in low reactivity loss rates with better control. Answered By . Fast breeder reactor does not produce more fuel than it is is provided initially. Answer. A breeder, with a conversion ratio greater than 1, results in a net creation of fissile materials but requires more U to be recycled in the reactor … So conservation of energy principle is not violated. Breeder reactor has a conversion ratio of (a) unity (b) more than unity (c) less than unity (d) zero (e) infinity. answr. "Breakeven" is achieved when the conversion ratio becomes 1: the reactor produces as much fissile material as it uses. 12. a.
