Investigation of the in uence of various re ector elements material types on thecore nuclear parameters of the 2 MW Triga Mark-II research reactor using theMonte Carlo code

Özet

The in uence of variation in the kind of material of neutron re ector elements on the core neutronic parametersof the Moroccan Triga Mark-II research reactor was examined. The comparison was made between three kinds of re ectorelement materials: graphite, beryllium, and beryllium oxide. MCNP5 Monte Carlo computations of the effective neutronmultiplication factor (keff) of the reactor according to the number of re ector material elements inserted in the reactorcore for these three re ector elements materials families were carried out. The results found could be used in order toincrease thekeffparameter without changing the size of the reactor.
