Requirements for Establishing Detector Siting Criteria in Fires Involving Electrical Materials.

摘要

Due to increased public awareness and regulatoty actions, significant strides have been made in the capabilities of fire technology as it applies to fire detection systems. However, these advances in detector selection, siting, reliability and approvals tests have not substantially addressed the overall fire protection requirements within nuclear reactors. This report emphasizes some of the basic requirements and considerations needed for establishing siting criteria for early-warning detection of electrical cable fires. Recent research in electrical cable flammability and damageability characteristics are discussed. Also current work in systemizing detector siting criteria is also described. Confirmatory tests linking assessment of electrical-cable damageability with electrical cable fire detection is stressed.
