APPENDIX A

19.8

List the parameters used and identify the indications of a degraded process.

19.9

State the potential problems of a degraded system or process, and discuss policies and

procedures that are used to diagnose and mitigate the situation.

Review basic concepts to familiarize the trainee with information that has

operational impact contained in the safety analysis report.

19.1, 19.2

Have a discussion with an individual knowledgeable in transient and

19.6-19.9

accident analysis, with an emphasis on providing the STA a thorough

operational understanding of transient and accident analyses that will

enhance the ability to make decisions during emergencies. Include a

discussion of the concepts and information that have operational impact

contained in the Probabilistic Risk Assessment. Operating experience

may be useful to relate the reasons and operational considerations

resulting from the analyses.

19.3, 19.4

Use a case-study approach with emphasis on understanding, evaluating,

and responding to the parameters affecting core heat transfer

capabilities and accident mitigation.

19.5, 19.6

A simulator (for those facilities that have them) should be used to

exercise implementation skills related to the application of transient and

accident analysis to events that could result in system or process

damage. This should be done to the extent that the simulator models

conditions approaching core damage. Emphasize the understanding

and skills needed to maintain and restore safety functions.
