Reflector TRIGA Mark II Bandung waste container shielding using Microshield 7.02 has been conducted. In 1996, TRIGA Mark II power was upgraded from 1MWt into 2MWt, and the reflector was one part of the reactor core that was changed. Reflector waste consists of graphite with activated Co-60. In 2015 the activity was 0.557 Ci with 1,221.5 Kg weight. This large radioactive waste needs to be removed from Bandung Nuclear Area into PTLR-Serpong Nuclear Area. This removal process needs calculations and the basic design of the waste container. Pure lead material is planned to be used for attaining requirements standards of radioactive container category base on Transport Index score. In addition, MicroShield 7.02 is a software that is used for helping to analyze shield thickness and could count exposure rate out of the waste container. This software was also used in this research to calculate the lead thickness and demonstrate the radioactivity in several points. The result of simulation with this software is; lead thickness for the container is 3 cm; the container category is III-Yellow with; Transport Index score is 189 or bigger than 10. With tubular shape with 3 cm thickness it will use 1,945.13 kg pure lead. Then, the dose rate on the surface of the container is 128.6 mSv/hr.
