- Abstract
- Fire models are used increasingly for fire safety assessment in nuclear power plants.
Examples of these fire models are CFD models and zone models. When using these
models it is important that they are sufficiently verified and validated. In Sweden the
majority of fire safety consultants are using FDS, developed by NIST. The verification
and validation of this package is intensively done for a number of scenarios by the developing
team. One of the recent modifications in FDS is the implementation of a ventilation
module. The first aim of this paper was to validate FDS and ANSYS-CFX within
the Swedish part of the OECD/NEA PRISME project using the PRISME SOURCE D1
test.... (More) - Fire models are used increasingly for fire safety assessment in nuclear power plants.

the Swedish part of the OECD/NEA PRISME project using the PRISME SOURCE D1
test. The results are presented in this article and show how powerful the module is for
simulation in enclosures with mechanical ventilation. Beside CFD models, fire safety
engineers need also simple empirical models for determining temperatures, smoke
heights, etc. In the second part of this paper such a model is developed. The model
predicts gas temperatures in a room adjacent to a room involved in a pre-flashover fire.
The correlation is derived with help of computer simulations and validated by means of
a set of fire tests. The results of the correlation model are satisfactory and the correlation
formulae will be an additional tool for fire safety engineers. (Less)
