Fission product model for BWR lattice calculation code.

Advanced Bwr Stability Analysis with a Reduced Order Model and System Code

The solution manifold of the system of nonlinear differential equations representing a BWR needs to be examined to understand its dynamical behavior. In particular, stable or unstable fixed points and stable or unstable oscillatory solutions (or turning points/saddle node bifurcations) are of paramount interest. In this framework integrated BWR (system) codes and simplified BWR models (reduced ...

Bwr Stability and Bifurcation Analysis Using a Novel Reduced Order Model and the System Code Ramona

A dynamic lattice model for heterogeneous materials

In this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. The Timoshenko beam theory is applied instead of the classical Euler-Bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. T...

Fission: Secure Dynamic Code-Splitting for JavaScript

Traditional web programming involves the creation of two distinct programs: a client-side frontend, a server-side back-end, and a lot of communications boilerplate. An alternative approach is to use a tierless programming model, where a single program describes the behavior of both the client and the server, and the runtime system takes care of communication. Unfortunately, this usually entails...

Piezonuclear Fission Reactions Simulated by the Lattice Model

Recent experiments conducted on natural rocks subjected to different mechanical loading conditions have shown energy emissions in the form of neutrons and anomalous chemical changes (“piezonuclear fission”). In the present study, we have used a numerical technique to simulate the anomalous nuclear products of piezonuclear fission. Specifically, the reactions were simulated by means of a nuclear...
