Division Spotlight
Mathematics & Computation
Division members promote the advancement of mathematical and computational methods for solving problems arising in all disciplines encompassed by the Society. They place particular emphasis on numerical techniques for efficient computer applications to aid in the dissemination, integration, and proper use of computer codes, including preparation of computational benchmark and development of standards for computing practices, and to encourage the development on new computer codes and broaden their use.

A day in the life of the nuclear community
The November issue of Nuclear News is focused on the individuals who make up our nuclear community.
We invited a small group of those individuals to tell us about their day-to-day work in some of the many occupations and applications of nuclear science and technology, and they responded generously. They were ready to tell us about the part they play, together with colleagues and team members, in supplying clean energy, advancing technology, protecting safety and health, and exploring fundamental science.
In these pages, we see a community that can celebrate both those workdays that record progress moving at a steady pace and the exceptional days when a goal is reached, a briefing is delivered, a contract goes through, a discovery is made, or an unforeseen challenge is overcome.
The Nuclear News staff hopes that you enjoy meeting these members of our community—or maybe get reacquainted with friends—through their words and photos.

This paper illustrates the capability of a global sensitivity analysis (GSA) framework applied to the TRACE thermal-hydraulics (TH) system code in the context of selected flooding experiments with blocked arrays reflood experiments. The proposed GSA framework deals with functional outputs (temperature profiles) and aims at quantifying the sensitivity of a specific feature of the reflood curve (its amplitude) to the physical parameters of TRACE. The framework uses a registration strategy based on the Square Root Slope Function (SRSF) transform to separate the amplitude and phase of the temperature profile. The registration is followed by a dimension reduction on principal component basis and the estimation of Sobol’ sensitivity indices. This paper compares the SRSF registration to the more traditional landmark registration and shows its excellent properties. Given the simple nature of the reflood curve, the Sobol’ indices obtained on the amplitude of the reflood curve also compare well with those obtained on the scalar maximum temperature of the curve. This suggests the framework to be of interest for deriving the sensitivity of the amplitude of more complex TH transients to the physical parameters of the code.
