PHYS-443: Physics of nuclear reactors

In this course, one acquires an understanding of the basic neutronics interactions occurring in a nuclear fission reactor as well as the conditions for establishing and controlling a nuclear chain reaction. ...

Description

Cette séance de cours couvre le calcul du facteur de picking, qui est le rapport entre le flux maximum et la valeur moyenne du flux. L'instructeur guide les étudiants à travers des exercices de résolution liés à ce concept, en mettant l'accent sur l'utilisation de formules et la compréhension de la relation entre les constantes et le pouvoir dans le processus.

Computation

A computation is any type of arithmetic or non-arithmetic calculation that is well-defined. Common examples of computations are mathematical equations and computer algorithms. Mechanical or electronic devices (or, historically, people) that perform computations are known as computers. The study of computation is the field of computability, itself a sub-field of computer science. The notion that mathematical statements should be ‘well-defined’ had been argued by mathematicians since at least the 1600s, but agreement on a suitable definition proved elusive.

AC power

In an electric circuit, instantaneous power is the time rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow. Its SI unit is the watt. The portion of instantaneous power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as instantaneous active power, and its time average is known as active power or real power.

Theory of computation

In theoretical computer science and mathematics, the theory of computation is the branch that deals with what problems can be solved on a model of computation, using an algorithm, how efficiently they can be solved or to what degree (e.g., approximate solutions versus precise ones). The field is divided into three major branches: automata theory and formal languages, computability theory, and computational complexity theory, which are linked by the question: "What are the fundamental capabilities and limitations of computers?".

Panne de courant

thumb|Court-circuit d'une ligne électrique à Troy, Illinois. Une panne de courant est la suspension de la distribution du courant électrique dans une région attribuée. Ceci peut provenir d'un défaut dans une centrale électrique, de l'équipement de distribution endommagé (par exemple, par une tempête de neige ou de pluie verglaçante), un court-circuit ou une surcharge du système. Le terme « blackout » est également utilisé lorsque la panne concerne un grand nombre de clients.

Model of computation

In computer science, and more specifically in computability theory and computational complexity theory, a model of computation is a model which describes how an output of a mathematical function is computed given an input. A model describes how units of computations, memories, and communications are organized. The computational complexity of an algorithm can be measured given a model of computation. Using a model allows studying the performance of algorithms independently of the variations that are specific to particular implementations and specific technology.
