Cable tray fire tests. [BWR; PWR]
Funds were authorized by the Nuclear Regulatory Commission to provide data needed for confirmation of the suitability of current design standards and regulatory guides for fire protection and control in water reactor power plants. The paper summarizes the activities of this program through March 1977. It describes a survey of industry in order to determine current design practices. The adequacy of cable tray spacing designated in Regulatory Guide 1.75 was chosen for evaluation. Using electrical cable types currently being selected for new nuclear power plant construction, a screening test was designed and completed to select two cable constructions which were used in subsequent full scale tests. Seven full scale tests were run and resulted in no functional damage to cables in trays adjacent to that cable tray in which a fire was electrically initiated. Characterization of these fires was made and reveal a margin of safety in the separation criteria of the regulatory guide for electrically initiated fires in IEEE-383 qualified cable.
