A.
See attached Table 2.
Q.
What is the containment air cooler fan and containment ~pray start time?
- 2.
A.
Assuming DBA conditions (LOCA with*coincident loss of off-site power) and failure of a diesel generator.
With the 1-2 diesel failed the only fan cooler is operational in 23 seconds.
The sprays, with two spray pumps available, are operational in 84 seconds.
With the 1-1 diesel failed one fan cooler is operational in.23 seconds and the remaining two in 33 seconds.
The sprays are operational in 104 seconds with one spray puinp available.
