Determination distribution characteristic core power density of Kartini reactor

Purpose of this research is determines big of neutron flux at platform Kartini Reactor and determines distribution of core power density Kartini Reactor. All changes in arrangement of fuel in rector core will have influence in neutron flux magnitude in each location (ring). Therefore after made a change the configuration hence need to be done measuring of neutron flux magnitude. This research of this neutron flux done in ring in core Kartini Reactor. This research applies activation method foil from material 197/79 Au. This measuring do at distance 20 cm, 25 cm, 30 cm, 35 cm, 40 cm, 45 cm, and 50 cm from fuel shell. Result of this research is highest neutron flux value at ring F is 2,52x10¹² neutron cm^-2s^-1, at ring E the highest neutron flux is 1,98x10¹² neutron cm^-2s^-1, at ring D the highest neutron flux is 2,48x10¹² neutron cm^-2s^-1, at ring C the highest neutron flux is 3,06x10¹² neutron cm^-2s^-1and at ring B the highest neutron flux is 3,76x10¹² neutron cm^-2s^-1. Distribution characteristic of power density core Kartini Reactor at ring F power density is 1,25 watts cm^-3, at ring E power density is 0,95 watts cm^-3, at ring D power density is 1,16 watts cm^-3, at ring power density is 1,41 watts cm^-3 and at ring B highest power density is 1,69 watts cm^-3.
