G-3. Building Number 1.
Building number 1 is a poured concrete structure with 3.1-m-thick walls and roof. The facility
has no windows. Leakage rate versus internal pressure is shown in Figure G-1. Building leakage
rates can be calculated using equation G-1.
log(y) = C0 + C1log(x)
(eq G-1)
where: C0 = 2.3007476
C1 = 0.59040570
y = leakage rate, L/s
x = internal pressure, Pa
