Abstract
The Egypt second research reactor have many irradiation channel, beam tubes and irradiation boxes, inside and omside die reactor core. The core reload configuration has great eft’ect on
This work contains the results of design arid safety analysis performed for the determination of Egypt second research reactor (ETR.R2) in-core fuel management strategy which fulfills neutronic design criteria, safety reactor operation, utility optimization and achieve the overall fuel management criteria .
A procedure was followed to design the fuel management strategy, a reference core and fuel management schemes were suggested according to the previous accumulated experience and the reactor irradiation demands. This reference core and its reference management strategy were studied and improved for the verification of operational conditions. From this study, a reference equilibrium core and a knowlegde of the core performance under diffirent operating condition were obtained.
Starting with the reference equilibrium core, some variables were studies simultaneously, the equilibrium core , the proposed fuel movement schemes and the obtained initial core and its depletion variable parameters.
A backword iteration was used to estimate the initial core from the estimated equilibrium core, the iteration starts with the estimated equilibrium core burp up distribution .The result of this iteration is some estimated initial cores.
Then starting with this estimated initial cores, using a two dimension code, the core is depleted in order to test the depletion behavior, during this step some obtained initial cores from the iteration are rejected as it violate some neutronic and fuel management criteria. From the last stage equilibrium cores are obtained, compared with the first estimated equilibrium core, some rejected and other remains , if it agree with it. A further analysis is performed in the intermediate cores and the equilibrium core for the verification of the operational conditions.
