FPoliSolutions demonstrates RISE, an RIPB systems engineering tool
The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) has held another presentation in its monthly Community of Practice (CoP) series. Former RP3C chair N. Prasad Kadambi opened the October 3 meeting with brief introductory remarks about the RP3C and the need for new approaches to nuclear design that go beyond conventional and deterministic methods. He then welcomed this month’s speakers: Mike Mankosa, a project engineer at FPoliSolutions, and Cesare Frepoli, the company’s president, who together presented “Introduction to RISE: A Digital Framework for Maintaining a Risk-Informed Safety Case for Current and Next Generation Nuclear Power Plants.”

The neutron capture and fission cross sections of 240 Pu have been measured from 20 eV to 30 keV. Transmission measurements were also made from 30 to 500 eV. The capture data were normalized using the transmission results to minimize the uncertainty in absolute normalization. The average capture cross section has been determined from 6 to 30 keV. The s-wave average radiation width has been found to be (0.0295 ± 0.0015) eV. Resonance parameters to 500 eV and an s-wave strength function of (1.10 ± 0.27) × 10−4 have also been obtained. Subthreshold fission structure was observed up to 30 keV. The level spacing for subthreshold fission was found to be (710 ± 200) eV. Comparisons of all our results are made to previously published data.
