PWR Fuel Assembly Modal Testing and Analysis

Flow-Induced Vibration, 2003
Pressurized Water Reactor (PWR) seismic or Lost Of Coolant Accident (LOCA) loads could result in impacts between nuclear fuel assemblies or between fuel assemblies and the core baffles. Forces generated during these shocks are often the basis for the determination of the maximum loads and of the spacer grid and fuel rod design.

Metallic wastes from fuel assemblies

Atomic Energy, 1994
Investigation of a pulsed pneumatic transportation system for spent fuel is briefly described. Testing parameters for air transport included nozzle optimization and transportation range. The range of particles (30 to 40 mm metal chunks) was determined as a function of the nozzle diameter.

Fuel Pin and Assembly Design

2011
This chapter deals with the mechanical designs of fuel pins and assemblies. These core components must be designed to withstand the high temperature, high flux environment of a fast spectrum reactor for a long irradiation exposure time. In this chapter we will describe many of the factors that influence this design, and we will examine in some detail ...

Numerical simulation of fuel assemblies containing pebble fuel elements

Thermal Engineering, 2010
A numerical calculation of the new fuel assembly for a VVER-1000 reactor containing fuel on the basis of pebble fuel elements is carried out. The reactor core pressure drop coefficients in the axial and radial directions are studied.

Fuel Pellet, Element and Assembly

2023
Fuels that are fabricated for water-cooled power reactors are based on ceramic uranium dioxide (UO2), sintered from the powder to form fuel pellets. Fuel pellets, usually about 10 mm to 12 mm in diameter and 10 to 15 mm in length, are stacked in zirconium alloy (i.e., zircaloy) tubes, forming fuel elements.

On the development of fuel assemblies

Experimental Thermal and Fluid Science, 1991
Abstract Investigations of RBMK fuel assembly models of various geometries were carried out to develop fuel assemblies with reduced uranium dioxide temperatures and decreased void reactivity effect. The investigations include thermophysical experiments and neutron and physical calculations.

Fuel assembly burnup calculations for VVER fuel assemblies with the MONTE CARLO code SERPENT

Kerntechnik, 2014
Abstract The Monte Carlo code SERPENT (http://montecarlo.vtt.fi) is tested and validated for different fuel configurations but not for VVER fuel assemblies with Gd fuel pins and enrichment profiling. The presentation outlines the results obtained during fuel assembly burnup calculations for VVER-440 and VVER-1000 reactor types with Gd ...
