The study analyzed the U‐235 burn evolution and the element remain in the research reactor IEA‐R1. The fuel elements are of the type MTR (Material Testing Reactor), the standard with 18 plates and a 12‐plate control, with a nominal mean enrichment of 20%.397-400openAccessburnupbrazilian cnenfissionfuel elementsiear-1 reactormaterials testingnuclear fuelsoperationplatesreactor control systemsreactor fuelingreactor safetyuranium 235Texto completo de evento10.1063/1.3608995
