حساب معامل التضاعف الفعال و توزع التدفق النتروني في مفاعل الطاقة VVER-640 باستعمال الكود MCNP5-beta

الملخص EN

The MCNP5-beta Monte Carlo code was used in this paper to model the VVER-640 nuclear power reactor, and to calculate the effective multiplication factor, delayed neutrons, and thermal and fast neutron fluxes distribution.

The values of the effective multiplication factor was 1.34311, and the value of delayed neutrons fraction was 0.007893.

The thermal flux in reactor core was 3.37.1013 (n/cm2 .s) and the fast flux 1.76.1014 (n/cm2 .s).

The results showed good agreements with the presently available results about VVER-640 reactor.
