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.
Meeting Spotlight

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Several investigators have demonstrated empirical relationships between creep and rupture properties for various metals and alloys. We have examined empirical relationships between the rupture life and the minimum creep rate and the time to the end of steady-state creep (start of tertiary creep) for four heats of normalized-and-tempered Cr—1 Mo steel with different carbon contents. The primary objective was the determination of the conditions that affect the correlation. The following relationships were obeyed: andt2 = Fs tr , where t2 is the time to start tertiary creep, tr is the rupture life, is the steady-state creep rate, and C and Fs are constants. The primary micro-structural constituent (proeutectoid ferrite or bainite) of the matrix and the precipitates present in that matrix (before test or formed during test) played a significant role in the correlation of the data with the empirical relationships.
