Abstract

Radiation safety analysis of nickel material neutron colimator (as requirement) for pearcing radial beamport utilization of Kartini research reactor has been done before the neutron colimator instaled. The neutron collimator made of nickel material with cyllindrical geometry which is 156 cm length. The Inside and outside diameter are 16 cm and 19 cm respectively with mean cyllindrical thickness is 1,5 cm. Irradiation process to the neutron collimator begin when the reactor beeing operated for 6 (six) hours per day and assumed optimum at 100 kW power level. Results of the analysis showed that gamma dose rate which was generated by collimator at a distance of 50 cm from the end of the collimator is 1,5328e-03 mr/hours. The dose rate is still below the dose limit value which was required by Nuclear Energy Regulatory Agency (BAPETEN) is 1 mr/hours. It can be concluded that utilization neutron colimator of nickel material which installed at the radial pierching beamport of Kartini Reactor is safelly.
