Deep Space: The new frontier of radiation controls
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

The U.S. Dept. of Energy (DOE) Office of Science and the National Nuclear Security Administration initiated the Exascale Computing Project (ECP) in 2016 to prepare mission-relevant applications and scientific software for the delivery of exascale computers to DOE in 2023. The ECP currently supports 24 science applications, 6 supporting co-design projects, and greater than 80 scientific software libraries in pursuit of this mission. In this talk I will introduce the ECP and give an overview of the application development focus area. The challenges associated with converting multiphysics scientific applications to heterogeneous computer architectures, and the approaches taken in the ECP, will be shown. I will discuss the programming models used in the ECP to achieve performance portability across a range of computer architectures. Finally, I will show highlights and discuss specific challenges in the ECP energy applications portfolio that consists of six projects modeling wind power, combustion, nuclear reactors, chemical looping reactors, fusion tokamak reactors, and plasma accelerators.
Radiation effects play an important role in nearly every aspect of our understanding of core-collapse supernovae, from neutrino transport in the dense central engine to the photon transport behind the luminous emission from the supernova blast wave. Modeling the radiation accurately is important in using observations of these cosmic explosions to understanding both the physical mechanism behind supernovae but also the fundamental physics behind supernova explosions. In this talk, I will review the different transport processes and some of the more challenging aspects of the transport modeling in these different regimes. I will focus on a new challenge posed by future NASA missions to model observations of supernova shock breakout.
