Abstract
This report examines the role of compartment ventilation
from the standpoint of nuclear power plant fire
protection safety. Based on a review of numerous
design standards which consider the influence of
controlled ventilation on reducing fire severity, the
report concludes that current standards and regulatory
guidelines inadequately define criteria for design of
ventilation systems and their operation under fire
emergencies. To resolve this deficiency, the report
evaluates four candidate design bases for ventilation
systems: smoke removal, smoke dispersion control,
fire spread control, and fire temperature control. It
is concluded that the lack of existing fire technology
precludes the implementation of all but one of these
criteria--fire temperature control. On this basis the
report presents an example design calculation for
applying the temperature control criterion.
