SRO PRO URO Event Description Remove EPR from service for maintenance Steam seal exhaust blower trips, start other blower Scenario Summary The scenario begins with the reactor at 100% power with the A CRD Pump out of service. The crew will begin by removing the EPR from service. The running steam seal exhaust blower trips. The crew will start the other exhaust blower. A reference leg leak will develop in a RPV Level instrument. The crew will take manual control of RPV level and transfer to the alternate signal. A loss of power to VMCC 1A2 will result in the crew restoring RPS and resetting the half scram. The Cy Feedwater Pump trips requiring the crew to reduce power to maintain reactor level. The only available CRD pump trips, which will require the crew to scram the reactor. A RWCU leak will occur in the Reactor Building requiring entry into Secondary Containment Control EOP. A RWCU valve will fail preventing the isolation of the leak. Emergency Depressurization will be required to mitigate the primary leak into the Reactor Building.

Scenario Summary The scenario begins with the reactor startup in progress at 5-1 0% power with mode switch in RUN.
Control rods will be moved to raise power. The crew will swap the Service Water Pumps. Running CRD pump trips, start standby pump. Reactor Level Instrument RE02A Fails Downscale causing the Core Spray to start but EDG #2 does not start and idle. Core Spray will be manually secured. APRM 4 will then fail upscale requiring the crew to evaluate Tech Specs, bypass the APRM, and reset the half scram. The running RBCCW pump trips requiring the standby pump to be started. An RPV steam leak will result in increase in Drywell temperature and pressure. Drywell pressure will increase requiring Drywell Sprays using the Containment Spray system. The drywell spray valve fails to automatically realign and must operated manually to permit sprays to function.

4 Scenario Summary The scenario begins with the reactor at 99% power with the A CRD pump out of service. The crew will begin by placing an alternate Reactor Building HVAC fan in service and secure the running fan. A Drywell recirculation fans trips and an alternate fan will be started. The RBHVAC ventilation radiation monitor will fail upscale, causing RBHVAC to trip, but the SGTS will fail to start. The crew will start the SGTS manually. A control rod drifts out and it will be restored to its programmed position. The running Service Water pump trips requiring the standby pump to be started. The rod drift will cause a small fuel failure. Power will be reduced to lower radiation levels. A leak in the Torus will require the Reactor to be scrammed and eventually this will lead to Emergency Depressurization. Five rods will fail to insert on the scram.
