4.8.3 REQUEST Operations align all other sumps to the High Level Waste Drain Tank Header per OP 3335B.

4.8.6 OPEN 3SSR-V779, "Containment Sump Liquid Sample Grab Valve."

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.

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.

4.22 Waste Test Tank B'Alternate Sample Point ALARA Radiological conditions may be more severe following an accident.

Health Physics assessment and support is necessary when sampling during post- accident conditions.

4.22.1 IF sample is being collected during post-accident conditions, PERFORM the following:

a. CONSULT with Health Physics and DETERMINE the following:
  • Protective clothing
  • Respiratory protection
  • Dosimetry a Route to be followed to and from sample point
  • Stay times
  • Expected dose and dose rate 0 Sample volume
  • Sample handling precautions
  • Any other Health Physics requirements needed to keep liquid PASS team personnel radiation exposure ALARA and to reduce the spread of radioactive material
