The NRC released a more detailed version of the Fort Calhoun Restart Checklist earlier this week. The major points in my opinion are:
Safety Culture
Containment Internal Structure design margin (not pressure boundary integrity)
Containment electrical penetration have potential LOCA level radiation degradation
Flood protection procedures and structures (Yellow finding, 2010)
Reactor Protection System contactor failure (White finding, 2011)
Electrical Distribution 480V breaker fire(Red finding, 2012)
