- 1.
How voiding in the reactor vessel upper head occurs, and the consequences.
- 2.
Identify observable signs that voiding is necessary.
- 3.
Discussion of procedures for preventing and mitigating voiding.
- 4.
Discussion of St Lucie event dated June 1980.
- 5.
Insure proper modeling of the reactor vessel upper head is in the Palisades simulator.
