Abstract:

Abstract
Neutronic analysis of a typical swimming pool type research reactor, Pakistan research
Reactor-1 (PARR-1), was carried out for determine the effect of graphite reflector
configuration modification as a way to optimize the neutron flux in the irradiation positions.
Standard computer codes WIMSD and CITVAP were employed to calculate core excess
reactivity, neutron fluxes, power distribution, and burn-up distribution. A comparison
between four different core configurations is presented in this article.
