Mechanistic Analysis of Glovebox Fire Propagation

PDF Version Also Available for Download.

Description

Propagation of a fire that originates in a single glovebox to other locations in the Plutonium Facility at Los Alamos National Laboratory is conceivable only if transport of hot combustion gases to other locations causes ignition of combustible materials elsewhere in the system (i.e., flashover). This paper describes a model developed, using the MELCOR computer code, to calculate the generation and transport of combustion gas mass and energy during postulated glovebox fire accident scenarios. The accident scenarios involved a wide spectrum of glovebox operating and potential fire conditions to determine whether flashover conditions could occur at locations outside the burning ... continued below

Description

Propagation of a fire that originates in a single glovebox to other locations in the Plutonium Facility at Los Alamos National Laboratory is conceivable only if transport of hot combustion gases to other locations causes ignition of combustible materials elsewhere in the system (i.e., flashover). This paper describes a model developed, using the MELCOR computer code, to calculate the generation and transport of combustion gas mass and energy during postulated glovebox fire accident scenarios. The accident scenarios involved a wide spectrum of glovebox operating and potential fire conditions to determine whether flashover conditions could occur at locations outside the burning glovebox: o A variety of combustible material characteristics was considered (e.g., type, quantity, and combustion properties of combustible material). o A spectrum of safety system operating conditions was considered (e.g., glovebox ventilation system operating normally vs an inoperative exhaust fan; drop-box fir e damper closure vs failure to close). o A range of analytical modeling assumptions was considered (e.g., the extent to which heat transfer between hot combustion gases and the glovebox walls is represented in the model). Example results of these calculations are presented to illustrate the benefits obtained and lessons learned by using a computational tool like MELCOR for this analysis.
