This paper talks about a resolved resonance evaluation carried out for 103Rh. Rhodium is one of the six most important fission product nuclides encountered in nuclear reactors with an important microscopic capture cross section which impacts results of calculations of spent nuclear fuel.
The buildup of fission products in spent nuclear fuel accounts for a reactivity decrease (burnup credit). Such burnup credit may lead to cost savings in packaging, transportation, and storage of spent nuclear fuel. The knowledge of 103Rh
cross sections and its corresponding uncertainties is therefore paramount in order to secure criticality safety margins.
