delayed neutrons उदाहरण वाक्य

उदाहरण वाक्य

1. As for delayed neutrons, do you think it is better to include them in nuclear fission or to leave them ( like now ) in nuclear reactor physics?
2. McElroy, R . D .; Clark, David D .; Yeh, T . R . Level parameters deduced from experimental beta-delayed neutron spectra.
3. This delayed neutron fraction, on the order of 0.007 for uranium, is crucial for the control of the neutron chain reaction in one dollar of reactivity.
4. A steady-state ( constant power ) reactor is operated so that it is critical due to the delayed neutrons, but would not be so without their contribution.
5. Filippone claims that unlike conventional water-cooled fission reactors, where fission occurring in Maxwellian thermal neutron flux profile, the neutron energy profile from delayed neutrons varies widely.
6. At the first level of control in all nuclear reactors, a process of delayed neutron emission by a number of neutron-rich fission isotopes is an important physical process.
7. These delayed neutrons account for about 0.65 % of the total neutrons produced in fission, with the remainder ( termed " prompt neutrons " ) released immediately upon fission.
8. However, if the mass is critical only when the delayed neutrons are included, then the reaction can be controlled, for example by the introduction or removal of neutron absorbers.
9. When differentiating between a prompt neutron versus a delayed neutron, the difference between the two has to do with the source from which the neutron has been released into the reactor.
10. The moment of beta decay of the precursor nuclides-which are the precursors of the delayed neutrons-happens orders of magnitude later compared to the emission of the prompt neutrons.
