APPENDIX B - EXAMPLE DRILL SCENARIOS
Loss of Non-1E Invertor, D-115
Drill Number: 062-01
Revision Number: 0
Initial Conditions: MHTS temp less than 450 0F, D-114 must be operating, HTS-S sampling
systems must be in a condition to allow an HTS CIS event, Reactor Cover
Gas Pressure at 10+2" W.G., Loop #1 control must be operable (52040-1),

Pre-drill Notifications: Mark space as notifications are made.
Safeguards and Security
Precautions and Limitations: No Mode 3 or 4 rod testing in progress. Forced cooling not
required in the IEM Cell.
Reactor Modes 3 or 4
Technical Safety Requirements: Control Room temperature < 100 0F; Reactor Cover Gas
Pressure >-20 < 40" (Mode 3) or > 0 < 40" (Mode 4); at
lease one LLFM (Mode 3) or two LLFM (Mode 4 fuel
handling in vessel). 188.8.131.52.2 LLFM Operability, 184.108.40.206
Control Room Temperature, 220.127.116.11.c Reactor Cover Gas
Pressure, 18.104.22.168.4 HTS Monitoring Instrumentation,
22.214.171.124.5 Control Room Instrumentation, 126.96.36.199
Post-Accident Monitors, 188.8.131.52 Pressure Transients.
Drill Team Duties: Ensure that actions and responses sufficiently control the casualty.
Evaluator: Monitor procedural usage and trouble-shooting techniques.
Do not allow reactor cover gas pressure or IEM cell pressure to exceed
Emergency Termination limits.
Drill Initiation: Drill Coordinator trips the D-115 AC output breaker and places a 3x5 card on it
stating that the breaker is in a trip-free condition.
