NOTE The containment drains sump sample line purge volume is 6.240 liters.
Due to the size of the sump and the capacity of the sump pumps, the pumps typically run for less than 1 minute when sump pumpdown is initiated. This short runtime does not allow for sufficient purge and sample collection. Because the containment drains sump pump discharge is the only input into this sample line, any sample collected from this point is representative of the contents of this sump at some time in the past. If desired, this section can be repeated several times to determine the present contents of the sump.
4.8.7 IF desired, REQUEST SM/US start 3DAS-P2A or 3DAS-P2B.
4.8.8 PURGE at least 6.240 liters.
4.8.9 COLLECT containment drains sump sample.

NOTE The containment drains sump sample line purge volume is 6.240 liters.
Due to the size of the sump and the capacity of the sump pumps, the pumps typically run for less than 1 minute when sump pumpdown is initiated. This short runtime does not allow for sufficient purge and sample collection. Because the containment drains sump pump discharge is the only input into this sample line, any sample collected from this point is representative of the contents of this sump at some time in the past. If desired, this section can be repeated several times to determine the present contents of the sump.
