Neutron stars velocities and magnetic fields

open access: yesEPJ Web of Conferences, 2018
We study a model that explain neutron stars velocities due to the anisotropic emission of neutrinos. Strong magnetic fields present in neutron stars are the source of the anisotropy in the system.

On the spectrum of moderated neutrons emitted by the isotropic source in the gas fuel

open access: yesЯдерна фізика та енергетика, 2016
Analytical formula for the equation of the neutron scattering for isotropic neutron source, which includes the temperature of the moderating medium as the parameter, was first obtained in the given work in the framework of gas model of the medium.

The Effect of Neutron Fluence at High Temperatures on Strength Nuclear Graphite: Based on Elasticity [PDF]

open access: yesE3S Web of Conferences
The main structural component and moderator in a high-temperature gas-cooled reactor (HTGR) is nuclear graphite. The long-term performance of these components is greatly influenced by exposure to high neutron fluence at operational temperatures above 600°

Enzyme activity and flexibility at very low hydration [PDF]

open access: yes, 2005
Recent measurements have demonstrated enzyme activity at hydrations as low as 3%. This raises the question of whether hydration-induced enzyme flexibility is important for activity. Here, to address this, picosecond dynamic neutron scattering experiments

Effect of Neutron Fluence Rate on Irradiation Embrittlement of Low-copper RPV Steel

open access: yesYuanzineng kexue jishu
The reactor pressure vessels (RPVs) of pressurized water reactor (PWR) nuclear power plants currently in operation and under construction in China are all made of low-alloy ferritic steels obtained by quenching and tempering treatments (which meet the ...

Impact of fuel temperature on nuclear core design calculations

open access: yesNuclear Engineering and Technology
The operation of a nuclear power plant relies on precalculated nuclear design predictions based on core calculations of various reactor states. The fuel temperature is a crucial factor in determining the reactor fuel behavior, but assessing the ...

Temperature Coefficient of Neutron Multiplication Factor [PDF]

open access: yesJournal of Nuclear Science and Technology, 1964
A method for calculating the temperature coefficient of the neutron multiplication factor in an infinite homogeneous medium is investigated for the purpose of discussion of the temperature coefficient for thermal reactors. Two kinds of expression for the temperature coefficient of the neutron multiplication factor are derived and given in terms of ...

Temperature Dependence of Phonons in Elemental Cubic Metals Studied by Inelastic Scattering of Neutrons and X-Rays [PDF]

open access: yes, 2009
The vibrations of atoms in a crystal (phonons) make up the majority of its entropy (or heat capacity), and these vibrations are typically modeled by simple harmonic oscillators.

Enzyme activity below the dynamical transition at 220K [PDF]

open access: yes, 1998
Enzyme activity requires the activation of anharmonic motions, such as jumps between potential energy wells. However, in general, the forms and time scales of the functionally important anharmonic dynamics coupled to motion along the reaction coordinate ...
