{{#Wiki_filter:Fire Modeling At the request of the Region III inspectors, an Office of Nuclear Reactor Regulation (NRR) fire protection engineer performed an analysis of the radiation protection office area to evaluate the potentially hazardous conditions (increased temperature and smoke layer level) that could be caused by a fire and assess the associated damage potential in the fire area.The staff concluded that hot gas layer temperature in the radiation protection office could reach in excess of 1,006 OF (540 °C) in 9 minutes. The staff's analysis was based on computer fire modeling of the radiation protection office using CFAST (Consolidated Model of Fire Growth and Smoke Transport).
{{#Wiki_filter:Fire Modeling At the request of the Region III inspectors, an Office of Nuclear Reactor Regulation (NRR) fire protection engineer performed an analysis of the radiation protection office area to evaluate the potentially hazardous conditions (increased temperature and smoke layer level) that could be caused by a fire and assess the associated damage potential in the fire area.
CFAST was developed by the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST) for fire modeling steady and unsteady state burning rates in multiple compartment configurations (multiple room capability, up to 15 rooms can be modeled) (Jones et al., 2000).The primary combustibles in the radiation protection office are open bookshelves with paper materials, offices chairs, tables, computers, open plastic recycle bin, and plastic trash can.Actual fire growth curves from testing have shown that the many common combustibles (e.g., cotton, polyester, mail bags, pallets stack) tend to be greater than the t 2 medium fire growth (Nelson, 1987). The t 2 relationship has proven to be useful and has been adopted into the National Fire Protection Association NFPA 72 to categorize fires for detector spacing requirements and into NFPA 92B for design of smoke control system. For the purpose of this analysis a t 2 medium fire growth rate for these fires was assumed for fire modeling.The main ignition sources in radiation protection office include coffee makers, toaster, pizza oven, freezer, microwaves, and printer. The electrical failure of one of the ignition source is postulated in this analysis to ignite the combustibles in the radiation protection office.Based on this information, the inspectors concluded that a fire in the radiation protection office area could adversely affect the post-fire safe-shutdown cable trays in the cable spreading area above due to heat being conducted and radiated through the metal decking.References Jones, W.

Fire Modeling At the request of the Region III inspectors, an Office of Nuclear Reactor Regulation (NRR) fire protection engineer performed an analysis of the radiation protection office area to evaluate the potentially hazardous conditions (increased temperature and smoke layer level) that could be caused by a fire and assess the associated damage potential in the fire area.

The staff concluded that hot gas layer temperature in the radiation protection office could reach in excess of 1,006 OF (540 °C) in 9 minutes. The staff's analysis was based on computer fire modeling of the radiation protection office using CFAST (Consolidated Model of Fire Growth and Smoke Transport). CFAST was developed by the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST) for fire modeling steady and unsteady state burning rates in multiple compartment configurations (multiple room capability, up to 15 rooms can be modeled) (Jones et al., 2000).

The primary combustibles in the radiation protection office are open bookshelves with paper materials, offices chairs, tables, computers, open plastic recycle bin, and plastic trash can.

Actual fire growth curves from testing have shown that the many common combustibles (e.g.,

cotton, polyester, mail bags, pallets stack) tend to be greater than the t2 medium fire growth (Nelson, 1987). The t2 relationship has proven to be useful and has been adopted into the National Fire Protection Association NFPA 72 to categorize fires for detector spacing requirements and into NFPA 92B for design of smoke control system. For the purpose of this analysis a t 2 medium fire growth rate for these fires was assumed for fire modeling.

The main ignition sources in radiation protection office include coffee makers, toaster, pizza oven, freezer, microwaves, and printer. The electrical failure of one of the ignition source is postulated in this analysis to ignite the combustibles in the radiation protection office.

Based on this information, the inspectors concluded that a fire in the radiation protection office area could adversely affect the post-fire safe-shutdown cable trays in the cable spreading area above due to heat being conducted and radiated through the metal decking.
