Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

The nuclear industry is pursuing the development and licensing of a number of advanced reactor designs of various technologies and sizes. Instrumentation and control (I&C) for these designs can play a key role in the operation and safety of the facilities. Multiple advanced reactor designers and applicants are in various licensing stages working closely with the United States Nuclear Regulatory Commission (NRC). The industry has submitted power reactor construction permit applications for advanced reactors, and they are currently under NRC staff review. Multiple designers have also been engaged with the NRC staff regarding I&C as part of the pre-application activities. In addition, the NRC has been preparing for the review of the advanced reactor licensing applications and developed various regulatory guidance on the risk-informed and performance-based (RIPB) approach with a goal for an efficient and reliable licensing review. The Advanced Reactor Content of Application Project (ARCAP), which encompasses the Technology-inclusive Content of Application Project (TICAP) spearheaded by the industry, led to issuance of a set of regulatory guidance that include Regulatory Guide (RG) 1.233, which endorses NEI 18-04, RG 1.253, which endorses NEI 21-07, and various Interim Staff Guidance documents. The implementation of the RIPB regulatory infrastructure provides opportunities and challenges for the I&C design and licensing. Specific to I&C, the NRC staff has also issued Design Review Guide (DRG) for I&C to be ready for the advanced reactors, and several designers are using this guidance. This panel will discuss the NRC staff and industry perspectives on the development and licensing of advanced reactor I&C. The emphasis for this panel is placed on the I&C-related regulatory infrastructure, the approaches of some of the designers, the industry implementation, challenges, and experience of such regulatory infrastructure, and the NRC perspectives.
