“…Works carried out by Chavez showed that an air gap of 2.54 cm may prevent fire spread from a fire cabinet to an adjacent cabinet. In contrast, the study conducted by Mangs et al highlighted that fire may spread between two fastened cabinets (ie, without air gap between them), and when samples of PVC cables are implemented in the adjacent cabinet. The results of the CORE‐6 test are thus consistent with the latter work, but they also show that the samples of HFFR cable types, located inside the PVC trunkings placed against the adjacent side wall of the adjoined cabinets, were not ignited.…”

Summary Electrical cabinet fire is one of the main fire hazards in nuclear power plants. As part of the OECD PRISME‐2 programme, four fire tests were carried out to investigate the fire spread from an open‐doors electrical cabinet to overhead cable trays and adjacent cabinets in a confined and mechanically ventilated facility. These tests, named CFS‐5 to CFS‐7 and CORE‐6, used same both cabinet (fire source) and three overhead cable trays. The trays were filled with a halogenated flame‐retardant cable‐type for CFS‐5 and one halogen‐free for the three other tests. Moreover, fire dampers were used for CFS‐7 test while CORE‐6 test implemented two additional cabinets adjacent to the fire source. Measurements such as flame and gas temperature, gas concentration, mass loss rate, and heat release rate were performed for investigating the fire spread. Cabinet fire spread to the cable trays for CFS‐5 and CFS‐6 tests. Three fast and short cable tray fires were shown for CFS‐5, while a slow and long cable tray fire was highlighted for CFS‐6. In contrast, the fire dampers shutdown for CFS‐7 test prevented ignition of the overhead cables. Furthermore, for CORE‐6 test, cabinet fire spread to the adjacent cabinets, but the upper cables were not ignited.

“…Calorimetric experiments were conducted by VTT during the 1990s (Mangs et al, 2003;Keski-Rahkonen, 1994, 1996) using electrical and electronic components as fire load within closed-door cabinets. The maximum HRR were measured in the 100-400 kW range.…”

“…Characterising the combustion of electrical cabinets under a calorimetric hood has, however, been attempted, in order to cope with this problem (Mangs et al, 2003) and to provide useful input data (mass loss rates, heat release rates, chemical reactions, soot production, etc.) needed to simulate fire scenarios properly for computer modelling.…”

“…Two experimental programs addressing the phenomenology of electrical cabinet fires have been conducted to study such fires in a free atmosphere: one in the United States conducted by SANDIA National Laboratories in the 1980s ( [5,6]) and a second on in Finland conducted by VTT in the 1990s ( [7][8][9]). More recently, Avidor et al from the University of Maryland ( [4]) have reported experimental simulations of electrical cabinet fires (approximately 40 tests) using propane and heptane as the fire load.…”
