“…In order to evaluate the isotopic ratios of the transmutation products the Multi-Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS) can be used. This technique has insured uncertainties lower than 0.5% (2  level of confidence) in measuring the isotopic ratio to the respect of that of the sample with a sensitivity as low as 10 -6 [12]. Filters can be used for mimicking the spectrum of the target reactor.…”

A number of advanced reactor concepts are planned for near-term demonstrations including microreactors, larger demonstrations and space nuclear systems. These reactor concepts are based on a wide variety of reactor technologies, including sodium, gas, and salt cooling. An overlooked area in the development and ultimate startup of these reactors is addressing nuclear data needs that allow confident prediction of the criticality, safety requirements, and operation of the reactors. In this paper we try to address the problem of assessing nuclear data needs and possible remedies to reduce the existing uncertainties for advanced nuclear reactors. A methodology for defining these needs is described. The case of the Molten Chloride Reactor Experiment (MCRE) has been considered and the related investigation highlights the specific needs for reducing uncertainty on the 235 U capture and 35 Cl (n,p) reactions. Relatively inexpensive integral experiments are indicated as possible solutions for significantly reducing the current associated uncertainties.
