1. The BOP operator will start SX 1C Pump IAW CPS No. 3211.01, Section 8.1.2 to perform PMT.

2. Annunciator CPS 5041-5H, Hyd Ignitor Sys Div 1 Trouble, is received. Technical Specifications will be evaluated and LCO 3.6.3.2, Action A1 will require the Hydrogen Ignitor Division to be restored to Operable status within 30 days.

3. Power reduction with flow will commence. Power reduction can be halted upon direction from the Lead Examiner by initiating next event.

4. Generator field voltage will start to increase requiring the ATC Operator to take manual control of the voltage regulator and adjust voltage. Annunciator CPS 5008-3E, Gen/Exciter Field Trouble, will also initiate alerting the operator to the problem.

5. The Shutdown Service Water (SX) pump, which is running for PMT, will trip. The BOP operator will need to open the 1SX014C valve to restore cooling water to the SX components. Technical Specifications LCO 3.7.2, Action A. will be evaluated which will require that HPCS be declared Inoperable immediately.

6. Annunciator 5004-2L, DCS Component Failure, causing a loss of the #4 and #8 DCS screens. This will require the RO to reroute the information by operating the DG 4 Bypass pushbutton on the P680 panel.

7. A trip of TBCCW Pump B will require the BOP Operator to start the standby pump.

8. Security will report that the Thunderstorm Watch has been upgraded to a Tornado Warning and that a Tornado has been sighted on the South edge of Clinton. A Tornado will tear through the RAT and ERAT causing a loss of off-site power. The Div II DG will fail to auto start.

9. A RCIC line break. will develop that simulates leakage into both the RCIC romm and the Steam Tunnel. This will cause entry into EOP-8, Secondary Containment Control as temperatures exceed Max Safe Values.
