@ Equipment performance was not meeting our expectations during 2003 and early 2004:
- Resources often pulled from prevention to reactive duties
- 28 days of lost generation in 2003 due to equipment problems
- Several unplanned events that required NRC interaction 2

OPERA MAKING e
NEW NUCLEAR SITE DIRECTIVE GHAT PROVIDES A FRAMEWORK FOR EVALUATING DECISIONS THAT HAVE THE POTENTIAL. TO AFFECT PLANT OPERATION OR OPERATIONAL MARGINS; PROVIDES A PROCESS FOR IDENTIFYING, EVALUATING, AND APPROVING OPERATIONAL DECISIONS; ALIGNS TO INPOs P INCIPLES FOR EFFECTIVE OPERATIONAL DECISION MAKING.
2
SIX PRINCIPLES OF OPERATIO DECISION MAKING Conditions that potentially challenge safe, reliable operation are recognized and promptly reported for resolution.
- Roles and responsibilities are established for making and implementing decisions and are thoroughly understood by plant personnel -
e Potential consequences of operational challenges are clearly defined and alternative solutions are rigorously evaluated.
e Decisions are based on a full understanding of short and long-term risks and the aggregate impact of conditions associated with various options.
Implementation plans are developed to effectively communicate actions, responsibilities, compensatory measures, and contingencies to ensure successful outcomes.
Decisions and decision-making activities are periodically evaluated.
3
M PROCESS
- An evaluation team is formed for each o erational decision makin (ODM) issue.
- Each ODM issue is documented to ensure operational decision-making processes are followed.
