PREVIOUS CALCULATIONS FOR OPTIMIZATION ALGORITHMS OF NUCLEAR FUEL RELOADING AT BUDAPEST RESEARCH REACTOR
22nd Symposium of AER on VVER Reactor Physics and Reactor Safety (2012, Průhonice, Czech Republic)
CORE DESIGN, OPERATION AND FUEL MANAGEMENT
Several questions occur during the core design calculation of the Budapest Research Reactor
like keep the limit of the power peaking factor and set the neutron flux of the irradiation
channels inside a desired interval. These problems can be solved with an acceptable choice of
the load pattern of the nuclear fuel elements. To determine what kind of load patterns are
preferable for the above discussed requirements preliminary calculations have been made for
random configurations of load pattern. Large number of random configurations overlaps the
search space therefore the desired parameters as function of load pattern are examined. The
data processing of the previous calculations based on statistical tools like correlation which is
a good method for earn information about a large database with large number of variables.
The main deal of the calculations is finding roles for creating load pattern whose parameters
are inside the prescribed interval. The results will be used in the future for different
algorithms of optimization.
