A Comparative Study of Effective Delayed Neutron Fraction
Influence of various sets of evaluated six-group delayed neutron parameters on kinetic parameters P e[f and P e f f / A is analyzed. The comparative study of the kinetic parameters is made for the coupled fast-thermal system HERBE at the Vinca Institute. Methods of calculation and measurement techniques used in this analysis are described. The results of calculations are compared with measureme...
متن کاملOne-run Monte Carlo Calculation of Effective Delayed Neutron Fraction and Area-ratio Reactivity
The Monte Carlo code MCNPX has been utilized to calculate the effective delayed neutron fraction and reactivity by using the area-ratio method. The effective delayed neutron fraction eff has been calculated with the fission probability method proposed by Meulekamp and van der Marck. MCNPX was used to calculate separately the fission probability of the delayed and the prompt neutrons by using th...
متن کاملProto-neutron and Neutron Stars
It has been shown that effective chiral hadronic models can satisfactorily describe nuclear matter, properties of finite nuclei as well as the structure of neutron stars1. While most of the approaches are based on variations of the linear sigma model or its non-linear realization, in the approach discussed here the scalar sigma meson serves to split the nucleon and its chiral partner (particle ...
متن کاملNeutron flux Measurement at Tapiro fast reactor for APD’s Irradiation fluence evaluation
The Avalanche Photodiodes (APD) were chosen as photon sensors for the barrel region of the CMS electromagnetic calorimeter. The LHC will be a hard environment for what concerns the radiation levels in the detectors. The most relevant damage on APDs is caused by neutrons that produce an increase in the dark current of these devices. In the CMS-ECAL collaboration a big effort was indeed done to u...
متن کاملEvolution of proto-neutron stars with quarks.
Neutrino fluxes from proto-neutron stars with and without quarks are studied. Observable differences become apparent after 10-20 s of evolution. Sufficiently massive stars containing negatively charged, strongly interacting, particles collapse to black holes during the first minute of evolution. Since the neutrino flux vanishes when a black hole forms, this is the most obvious signal that quark...
