ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

The purpose of this paper is to present a qualification methodology for software tools for nuclear safety I&C applications. When tools are used for development or verification & validation (V&V) of safety instrumentation & controls (I&C) software, their correctness has to be assured so that the tools can perform their intended function and would not mask any errors in software being developed or V&Ved. Therefore, it is important to thoroughly evaluate tools before they are used. The evaluation using proven methodologies shall result in confidence in using the tools because they are then qualified. IEEE Std 7-4.3.2-2003 provides guidance for qualifying software tools, which requires that software tools used to support software development processes and V&V processes shall be controlled under configuration management. One or both of the following methods shall be used to confirm the software tools are suitable for use: First (1), a test tool validation program shall be developed to provide confidence that the necessary features of the software tool function as required. And second (2), the software tool shall be used in a manner such that defects not detected by the software tool will be detected by V&V activities. Finally, tool operating experience may be used to provide additional confidence in the suitability of a tool, particularly when evaluating the potential for undetected defects.
