Suggested Learning Activities:

Objectives

None

Review basic concepts covered in previous nuclear facility/reactor

operator training to refamiliarize the trainee with information contained in

the facility safety analysis report and plant operating limits.

21.1-21.5, 21.9

Have a discussion with an operations instructor (having individual

knowledge of facility design criteria) on fundamental design

considerations and the relation of these considerations to facility

operation and operating limits. Stress aspects of design that affect

facility safety, including systems important to mitigating facility transients.

Discuss the role of design bases and operating limits in minimizing the

potential for adverse interactions among systems (e.g., adjustments of

cooling water to a large component may affect cooling to other

components served by that cooling water system). Discuss

environmentally qualified equipment and the impact upon facility

operation if environmental qualification deficiencies are encountered.

ALL

Review (reading and self-study) and discuss with an engineering

representative data from selected safety analyses involving facility

vulnerabilities, dominant damaging events, important systems and

equipment, and key operator actions for event mitigation as a result of

facility-specific design characteristics.

21.6-21.8

Use a case study approach to a facility-specific, challenging, and

plausible event(s) that addresses the potential of putting the facility

outside the design bases, such as loss of residual heat removal.

Operating experience may be used to support this activity. (A simulator

may also be used for demonstration following classroom discussion.)
