Bazı Nükleer Reaktör Kontrol Çubuğu Malzemelerinde Yüklü Parçacık Giricilik Mesafesi ve Kütle Durdurma Gücü Hesaplamaları

İnsanlığın karşılaştığı artan enerji talebine olası bir çözüm, fisyon mekanizmasıyla çalışan nükleer reaktörler olarak gösterilebilir. Bu tesislerin çalışmalarını takip edebilmek için, aralarında hayati öneme sahip olarak gösterilebilecek kontrol çubuklarının da bulunduğu ve tamamı birlikte çalışabilecek şekilde tasarlanmış pek çok ekipman bulunmaktadır. Bu bileşenlerin fiziksel-kimyasal özellikleri ve farklı etkileşimlerdeki davranışları gibi malzeme özellikleri yadsınamaz bir öneme sahiptir. Bu nedenle, bu bileşenlerin üretiminde kullanılan malzemelerle ilgili olası tüm bilgilerin toplanması son derece önemlidir. Bu önem göz önünde bulundurarak bu çalışmada, nükleer reaktör kontrol çubuklarında kullanım olasılığı bulunan bazı materyaller için kütle durdurma gücü ve yüklü parçacık giricilik mesafesi 1-50 MeV enerji aralığındaki alfa, 3He, triton, döteron ve protonlar için en çok bilinen bilgisayar destekli hesaplama ve benzetim programları olan GEANT4 ve MCNP kullanılarak yapılmıştır. Her iki koddan elde edilen sonuçlar grafikle görselleştirilmiş ve birbirleriyle kıyaslanmıştır.

Charged Particle Penetration Distance and Mass Stopping Power Calculations on Some Nuclear Reactor Control Rod Materials

One possible solution to the increasing energy demand, which mankind has been facing through, might be pointed as the nuclear reactors that work with the fission mechanism. In order to pursue the operation of these facilities, many equipment have been designed in a way that all of them could operate together where the control rods could be given as one of the vital parts among them. Material properties of these components, such as physical-chemical characteristics and their behaviors under different interactions, have an undeniable importance. Due to that, gathering all the possible information about the materials used for the production of these components is extremely important. By considering this importance, in this study, the mass stopping power and charged particle penetration distance calculations have been done for some materials which have possible usage in nuclear reactor control rods using alphas, 3He, tritons, deuterons and protons within the energy range of 1-50 MeV via employing two of the most known computer aided calculation and simulation software which are GEANT4 and MCNP. Obtained results from both codes have been visualized by graphing and compared with each other.
