NANOTECHNOLOGY FOR ADVANCED NUCLEAR THERMAL-HYDRAULICS AND SAFETY: BOILING AND CONDENSATION

Large-Scale Simulations on Thermal-Hydraulics in Fuel Bundles of Advanced Nuclear Reactors

In order to predict the water-vapor two-phase flow dynamics in a fuel bundle of an advanced light-water reactor, large-scale numerical simulations were performed using a highly parallel-vector supercomputer, the earth simulator. Although conventional analysis methods such as subchannel codes and system analysis codes need composition equations based on the experimental data, it is difficult to ...

Thermal Hydraulics Design Limits

The following discussion of PWR steady state and transient design limits is extracted from the theses of Carter Shuffler and Jarrod Trant while the BWR discussion is extracted from Paolo Ferroni's thesis (covers steady state only). These limits are a simplified and narrower discussion than the relevant NRC standard review plan you will also be referred to. All materials are directly extracted f...

Appendix 1 Thermal Hydraulics, Draft for Comment

Several different fuel failure criteria have been used in previously NRC-sponsored SFP accident studies. Benjamin, et. al. used the onset of runaway fuel clad oxidation as the fuel failure criterion in NUREG/CR-0649 [Ref. 1]. This criterion was criticized because clad rupture can occur at a relatively low temperature causing a gap release. The consequences of gap release can be significant if t...

Thermo-hydraulics of Nuclear Reactors

This book provides a concise and up-to-date summary of the essential thermo-hydraulic analyses and design principles of nuclear reactors for electricity generation. Beginning with the basic nuclear physics, it leads through technical and quantitative analyses to descriptions of both the normal operation of the various modern nuclear reactor designs and the analyses of the possible departures fr...
