The Use Of 6/1 Pattern In The Fuel Loading Of 2.96GU/CC Silicide RSG-Gas Core

Change of the RSG-GAS loading pattern from 6/1 or 6/2 pattern to 5/1 pattern has been reduced a generated energy for each cycle operation. Therefore, it is necessary to research fuel loading pattern of RSG-Gas. Loading pattern proposed in this research is 6/1 meaning 6's fuel element and 1 control element loading in the reactor for each cycle operation. To know neutronic characteristic of 2.96 g U/cc silicide RSG-Gas core using 6/1 loading pattern, the calculation of 2 dimensional of core had been done using SRAC-ASM BURN computer code. Calculation results showed that core with 6/1 loading pattern can increase the energy for each cycle operation about 180,6 MWD, the core operation more effective 24,15 day, and fuel discharge burn-up increase average of 5.716%235U for each fuel compared core with 5/1 loading pattern. The core with 6/1 loading pattern is more efficient in the use of the fuel, because with different 2 fuel element/years, the raised energy was higher about 726.762 MWD/y equivalent to 1 cycle operation
