1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
Q41 ⇒ U238 will undergo fission by high energy (fast) neutrons alone [other wrong options] [Discuss in forum] low energy (slow) neutrons alone either fast or slow neutrons medium energy neutrons none of the above. |
Q42 ⇒ A reactor capable of converting a ferrite material into fissile isotopes is called regenerative reactor [other wrong options] [Discuss in forum] fast breeder reactor breeder reactor boiling water reactor ferrite reactor. |
Q43 ⇒ Hydrogen is preferred as better coolant in comparison to C02 because former has high specific heat [other wrong options] [Discuss in forum] is lighter is inert is a good conductor all of the above. |
Q44 ⇒ Natural uranium is made up of 99.282% U238, 0.712% U235, 0.006% U234 [other wrong options] [Discuss in forum] 99.282% U235, 0.712% U238, 0.06%' U234 99.282% U234, 0.712% U238, 0.006% U235 99.282% U235, 0.712% U234, 0.006% U238 none of the above. |
Q45 ⇒ The risk of radioactive hazard is greatest in the turbine with following reactor boiling water [other wrong options] [Discuss in forum] pressurized water gas cooled liquid metal cooled all of the above. |
Q46 ⇒ Plutonium is produced by neutron irradiation of Uz [other wrong options] [Discuss in forum] as basic raw material by neutron irradiation of thorium artificially in high capacity furnace. |
Q47 ⇒ Electron-volt is the unit of energy [other wrong options] [Discuss in forum] atomic power voltage radio activity there is no such unit. |
Q48 ⇒ Pick up the wrong statement Fast reactor uses moderator [other wrong options] [Discuss in forum] In a heterogeneous or solid-fuel reactor, the fuel is mixed in a regular pattern within moderator. Slow or thermal neutrons have energy of the order or 0.025 eV Fast neutrons have energies above 1000 eV Most serious drawback in using water as coolant in nuclear plants is its high vapor pressure. |
Q49 ⇒ The unit of radio-activity is curie [other wrong options] [Discuss in forum] electron-volt electron-ampere MeV AMU. |
Q50 ⇒ Pick up the wrong statement Fast breeder reactors use water as coolant. [other wrong options] [Discuss in forum] operate at extremely high power densities. are liquid-metal cooled produce more fuel than they consume are unmoderated |
