The general-purpose Monte Carlo code MCNP can be used for neutron, photon, or coupled neutron-photon transport, including the capability to calculate eigenvalues for critical systems. The code treats an arbitrary three-dimensional configuration of materials in geometric cells bounded by first- and second-degree surfaces and some special fourth.

    Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. Monte Carlo Integration of the Adjoint Gamma-Ray Transport Equation. Emphasis is put upon requirements for calculation of effects in shielding. The massive shielding around the reactor and the concrete floors are preventing particle transport in the foundations and the thick concrete structures around the nuclear reactor, such as biological shield and concrete walls/floors, produce heavy shielding against ionising radiation, which results with some white areas (no results.

Monte Carlo Methods for Particle Transport teaches appropriate use of the Monte Carlo method, explaining the method’s fundamental concepts as well as its limitations. Concise yet comprehensive, this well-organized text: Introduces the particle importance equation and its use for variance reduction.

Nuclear Particle Transport with Emphasis on Monte-Carlo and Shielding Calculations by Peter Kirkegaard The Danish Atomic Energy Commission Research Establishment Risfl Reactor Physics Department Abstract A description is given of a number of methods of calculating the trans­ port of neutrons and Y-rays, mainly in reactor shields.

Emphasis has been laid on the Monte-Carlo Author: P. Kirkegaard. "This is a very solid book for graduate students in nuclear engineering to learn how the Monte Carlo method can be used to solve reactor physics problems.

It covers the fundamentals of Monte Carlo simulations before discussing how the technique can be used to solve fixed and fission sources neutron transport by: Abstract Attention is focused on the application of the Monte Carlo method to particle transport problems, with emphasis on neutron and photon transport.

Topics covered include sampling methods, mathematical prescriptions for simulating particle transport, mechanics of simulating particle transport, neutron transport, and photon transport. The left side of equation (2) is the uniform distribution between 0 and 1 and f(y) is the distribution needed.

In this way any distribution can be made with a uniform distribution. Monte Carlo results are obtained by simulating particle histories and assigning a score x i to each particle history. The particle histories typically produce a range of score depending on the selected by: LA-UR - 13.

Monte Carlo Calculations. • After a particle emerges from source or collision, or if the particle is entering a new cell:.

Monte Carlo N-Particle Transport (MCNP) is a general-purpose, continuous-energy, generalized-geometry, time-dependent, Monte Carlo radiation transport code designed to track many particle types over broad ranges of energies and is developed by Los Alamos National Laboratory.

Specific areas of application include, but are not limited to, radiation protection and dosimetry, radiation shielding, radiography, medical physics, nuclear criticality safety.

FLUKA, is a multipurpose transport Monte Carlo code, for calculations of particle transport and interactions with matter, covering an extended range of applications spanning from proton and electron accelerator shielding to target design, calorimetry, activation, dosimetry, detector design, Accelerator driven systems, cosmic rays, neutrino physics.

Carlo methods. The Monte Carlo simulation (in this paper we use the terms, ‘Monte Carlo simulation and code’ as ‘Monte Carlo simula- tion and code for particle transport’ ‘ particle ’ as neutron and/or photon ’) mainly consists of three parts, i.e., particle tracking, collision analysis and statistical calculation.

Modern computing capabilities are such that it is feasible to design a radiotherapy linear accelerator bunker based only on Monte Carlo calculations.

MONTE CARLO IN RADIATION THERAPY. The Monte Carlo techniques have been used in various branches of radiation therapy,[8,9] from simulation of radiation therapy equipments and sources to dose calculation in various geometries.[10–18] For simulation of the photon and electron particles one has to apply the physics of transport for modeling, which requires the knowledge of interactions of the.

4. Principles of Monte Carlo Basic idea of Monte Carlo method is to calculate the travelling distance of each neutron. We need to propagate the neutron trajectory in the reactor like it really behaves (the best way is 'to think like a neutron').

Republished with same title by the American Nuclear Society.Much emphasis has been placed on the fact that the explosion in computer power has enabled Monte Carlo transport simulations to be performed that were previously impractical.

Much less attention has been given to the idea that simply being able to calculate hundreds of millions, or even billions of particle histories may not ensure an accurate solution if the simulation is limited by nuclear.
