BNCT utilizes thermal neutron capture by boron compounds that have been injected into the patient's body. In Indonesia, BNCT research has been carried out by the National Atomic Energy Agency (BATAN) using the Kartini reactor as a neutron source. The collimator is a supporting facility to produce neutron fluxes that comply with IAEA (International Atomic Energy Agency) standards for BNCT, namely 1 × 109 n / cm2s. The nuclear facilities used will require protection, so BATAN has also designed paraffin shielding. Paraffin shielding is a radiation shield made of paraffin which is coated with aluminum AA 1100 as a protection. To create the aluminum casing, the Gas Tungsten Arc Welding (GTAW) technology is used with argon as an inert gas. Testing of Brinell hardness and metallography values were carried out to determine changes in mechanical properties. As a result, in the aluminum weld area, the hardness value decreased to 90.235 HBW. The welding area which was given annealing process also decreased to 77.325 HBW. The metallography that has been carried out shows that the FeAl3 phase distribution can reduce the hardness value of aluminum. %Z Dr. Nita Handayani. S. Si., M. Si
