At 40 m upstream sections temperature and air speed
measurements were located at several heights (Figure 6). At 5 m
downstream section temperature was measured (Figure 7) and at
840 m downstream section temperature, air velocity, O 2 and CO
concentration and humidity were measured (Figure 8).
These measurements permitted to evaluate cooling capability of
the water mist system and fire heat release in order to evaluate
control and suppression capability. Calculation of heat released
were based on oxygen consumption calorimetry technique.
Water mist system was located above fire area located at 5.2 m height.
Water was discharged in a single 50 m long section (Figure 9).

3. Fire Scenarios And Results
30 MW Pool Fire:
First scenario tested was a 6 diesel pool fire configuration. Each
pool was 1.2 x 1.6 m with a heat release about 4 and 5 MW (Figure
10).
Additionally a target wood pallet and bucket of water were located
at 6 m and 2.5 m downstream in order to evaluate water mist
system capability to avoid fire spread and radiation attenuation to
avoid tank vehicles to achieve dangerous temperature increase.
