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.

Geological work begins on Poland’s first nuclear plant
Project management firm Bechtel started site geological surveys for Poland’s first nuclear power plant project, the company announced on Wednesday.
Bechtel will conduct in-depth geological surveys at the Lubiatowo-Kopalino site in the Pomeranian municipality of Choczewo, in northern Poland. This is a key milestone for the country’s entry into nuclear power production, as the surveys will inform the suitability of the planned site.

The purpose of this paper is to provide an overview of the development of the Diversity and Defense-in-Depth (D3) strategy for the TerraPower Traveling Wave Reactor, TWR-300 Advanced Nuclear Power Plant. Previously, a D3 analysis was performed for the TWR-P Digital Control System (DCS) being designed by TerraPower for the TWR-P (prototype) reactor design. This paper provides an update on the D3 report specifically applicable to the TWR-300, which will be the first TWR Plant deployed. The Instrumentation and Control (I&C) design and configuration were based on standard digital control products. The control systems making up the DCS were selected because of their applicability to the functions required by TerraPower and the United States Nuclear Regulatory Commission (USNRC). The recommended installation of a digital-based Plant Protection System (PPS) and other systems throughout the TWR-300 enhances safety in many areas when compared to the previous generation of analog-based instrumentation systems.
