İleri ve Geri Saçılma İçin Difüzyon Uzunluklarının PN ve Modifiye UN Metodu ile Hesaplanması

Öz

Tek boyutlu nötron transport denkleminde difüzyon uzunluğu hesaplamaları için Modifiye U1 ve P1 yaklaşımları kullanıldı. Yaklaşımlar ileri-geri saçılmalı tek hızlı nötron transport denklemine uygulandı. Analitik difüzyon uzunluğu denklemleri elde edildi ve farklı çarpışma parametreleri (c) için U1 ve P1 yaklaşımından elde edilen sayısal sonuçlar birbiri arasında kıyaslandı.

Calculation of Diffusion Lengths using PN and Modified UN Method for Forward and Backward Scattering

Öz

Modified U1 and P1 approximations are used for the calculation of diffusion lengths in one- dimensional neutron transport equation. The approximations are applied to one-speed neutron transport equation with forward and backward scattering. Analytical diffusion length equations are obtained and the numerical results obtained from modified U1 and P1 approximations for different collision parameters (c) are compared with each other.

Anahtar Kelimeler

• : U1 Approximation
