  Reactor Physics
  The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

  DOE report: Cost to finish cleaning up Hanford site could exceed $589 billion
  The cost to complete the cleanup of the Department of Energy’s Hanford Site in Washington state could cost as much as $589.4 billion, according to the 2025 Hanford Lifecycle Scope, Schedule, and Cost Report, which was released by the DOE on April 15. While that estimate is $44.2 billion lower than the DOE’s 2022 estimate of $640.6 billion, a separate, low-end estimate has since grown by more than 21 percent, to $364 billion.
  The life cycle report, which the DOE is legally required to issue every three years under agreement with the U.S. Environmental Protection Agency and Washington State Department of Ecology (Ecology), summarizes the remaining work scope, schedule, and cost estimates for the nuclear site. For more than 40 years, Hanford’s reactors produced plutonium for America’s defense program.

See you in Indianapolis!

The theme for this year’s meeting is: “Failure is not an Option.” Yes, we have seen historic U.S. investments in nuclear technology in the last two years. Nuclear optimism is at a generational high. However, tough challenges remain: a laborious licensing process, a domestic enrichment gap, lack of progress on nuclear waste policy, a steep scale-up of our workforce and supply chains, demonstrating first of a kind fission and fusion technologies, just to name a few. It’s become increasingly clear that the world will not be able to solve its most fundamental climate and energy challenges without the power of nuclear technology, As such, we cannot afford to merely kick these challenges down the road. We must face them head on. If nuclear fails, the planet fails. That is not an option.
