o Significant open items.
- AREVA has been contracted to investigate containment closure requirements during a LODHR accident. Specifically, this may result in (i) the ability to cut the liner plate while still defueling and (ii) start refueling before the liner plate has been welded in place, tested and inspected.

- The. Reactor Building purge exhaust fans are operational
- The Reactor Building supply fans are shut down
- If the purge exhaust must be shut down then either the personnel hatch or equipment hatch openings must be closed
- Monitor the Reactor Building recirculation system by using RM-A6 or by taking general area air samples.
Other considerations to be considered when the liner is breached are:
" Run the main purge long enough to assure cleanup of the RB atmosphere
- Degas and depressurize the Reactor Coolant System.
