Task Overview
Objective
The first step in a Fire PRA is to define the physical boundary of the analysis, and to divide the area within that boundary into analysis compartments.
Purpose
For the purposes of a fire Probabilistic Risk Assessment (PRA), the plant is divided into a number of fire compartments. The analysis then considers the impact of fires in a given compartment, and fires that might impact multiple compartments. This procedure establishes the process for defining the global plant analysis boundary and partitioning of the plant into fire compartments. The product of this task will be a list of plant fire compartments in the nuclear power plant under analysis.
Scope
The work package developed to support the plant-partitioning task should address the following issues:
- Basis for and identification of the limits of the selected global plant boundary,
- Basis for and results of partitioning the selected global plant boundary into fire compartments,
- Mapping of fire compartments to plant fire areas defined in regulatory compliance activities, and
- Documentation of the basic features of some or all fire compartments.
