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
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Finite difference techniques for the solution of the motion of an elastic-plastic solid are used to investigate the effect of rock strength and the cavity gas properties on the cavity size formed by a nuclear explosion. The material description includes the effect of pressure and temperature on the yield surface and the change of material description in the solid, liquid, and vapor phases. The results presented indicate a strong dependence of cavity size on the rock strength and a considerably lower sensitivity to the ideal gas coefficient, γ, assumed for the cavity gas. The results suggest that the cavity sizes observed in nuclear field tests can be better correlated with calculations by assuming strength parameters considerably lower than observed in laboratory tests on competent rock samples.
