Overview This module describes the main systems of low power (< 2MW) and higher power ( = 2 MW) TRIGA reactors. The most significant difference between the two is that forced reactor cooling and an emergency core cooling system are generally required for the higher power TRIGA reactors. However, those TRIGA reactors that are designed to be operated above 3 MW also use a TRIGA fuel that is specifically designed for those higher power outputs (3 to 14 MW). Typical values are given for the respective systems although each TRIGA facility will have unique characteristics that may only be determined by the experienced facility operators. Due to the inherent wide scope of these research reactor facilities construction and missions, this training module covers those systems found at most operating TRIGA reactor facilities but may also discuss non-standard equipment that was found to be operationally useful although not necessarily required. The expected audience for this training consists of designated, certified or licensed reactor operators, operator trainees and regulators with some experience in nuclear reactor facilities and operations. The material is specifically directed at TRIGA reactor facilities but many of the systems described would also be required, perhaps with modifications, at any research reactor facility.
