A set of fire scenarios based on identified fuels and possible ignition sources has been presented. A qualitative risk assessment has been made for each scenario. The level of risk is approximately the same for most of the identified scenarios; no one sce nario presents significantly greater risks. In no case has it been found that a clearly possible fire scenario results in a severe loss (risk class 3). Operation of the facility with the mitigations given in this document may be undertaken with an accepta ble level of risk. A summary of hazards and their risk classes is given in See Also: A summary of scenarios and risk classes. The relevant mitigations are summarized in each individual scenario section.
A number of improvements can be made to decrease the total fire risk. These are detailed in See Also: Future Upgrades. Most of these would provide only incremental improvement. A significant improvement, however, would be obtained by providing automatic, early-stage, clean fire suppression systems for each fuel. Although developing such a system is a multi-year research project, the total fire risk would be significantly smaller.
