Reaktorsfræði

Reaktorsfræði is the Icelandic term for reactor physics. It is the scientific study of nuclear reactors, focusing on the fundamental principles that govern their operation. This field investigates the behavior of neutrons within a reactor core, including their production, absorption, and scattering. Key aspects of reaktorsfræði include understanding neutron diffusion, criticality, and the chain reaction process.

Central to reaktorsfræði is the concept of neutron flux, which describes the density of neutrons and their movement. Calculations in reaktorsfræði are crucial for determining reactor core design parameters, such as the amount and arrangement of fuel, moderator, and control elements. It also involves analyzing the effects of temperature, pressure, and material composition on reactor behavior.

Reaktorsfræði plays a vital role in ensuring the safe and efficient operation of nuclear power plants and research reactors. It underpins reactor control strategies, accident analysis, and the development of new reactor designs. The field draws heavily on nuclear physics, neutron transport theory, and computational methods to model and predict reactor performance. Understanding reaktorsfræði is essential for nuclear engineers and physicists involved in the nuclear industry.
