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.
Meeting Spotlight
Nuclear Energy Conference & Expo (NECX)

A simple estimation of the absolute value of the error in the dependence of the step number performed for the implicit (backward) Euler method has been derived for the case of a single ordinary differential equation (ODE). This estimation distinctly shows the way and the degree to which the implicit Euler method (recommended in user guides for the RELAP4 family of codes) can give more inaccurate results than the explicit (forward) method. The short and simple reasoning presented should be treated as an indication of the problem. Error estimation for a general system of ODEs is an extremely difficult and complex task, and it is still not completely solved.
