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 کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Estimation of neutron effective dose from DD and DT neutron generators and the design of appropriate shield for standing user
Neutron Generators (NG) are used as a neutron source for different applications. During recent years, major efforts are underway to develop a high yield compact NG. In this way, radiation protection aspects need to be considered during the operation of these high yield NGs. In this paper the neutron effective dose of a NG operator has been calculated using MCNPX Monte Carlo code. The results sh...
