Emergency&AbnormalPlantEvolutionsTierGroup5N/AN/A314For Tier 3, select topics from Section 2 of the K/A catalog, and enter the K/A numbers, descriptions, IRs,and point totals (#) on Form ES-401-3. Limit SRO selections to K/As that are linked to 10 CFR 55.43.Absent a plant-specific priority, only those K/As having an importance rating (IR) of 2.5 or higher shall be selected.Use the RO and SRO ratings for the RO and SRO-only portions, respectively.Select SRO topics for Tiers 1 and 2 from the shaded systems and K/A categories.The generic (G) K/As in Tiers 1 and 2 shall be selected from Section 2 of the K/A Catalog, but the topicsmust be relevant to the applicable evolution or system. Refer to Section D.1.b of ES-401 for the applicable K/As.On the following pages, enter the K/A numbers, a brief description of each topic, the topics' importance ratings (IRs)for the applicable license level, and the point totals (#) for each system and category. Enter the group and tier totalsfor each category in the table above; if fuel handling equipment is sampled in other than Category A2 or G* on theSRO-only exam, enter it on the left side of Column A2 for Tier 2, Group 2 (Note #1 does not apply). Use duplicatepages for RO and SRO-only exams.23Select topics from as many systems and evolutions as possible; sample every system or evolution in the group before selecting asecond topic for any system or evolution.Ensure that at least two topics from every applicable K/A category are sampled within each tier of the ROand SRO-only outlines (i.e., except for one category in Tier 3 of the SRO-only outline, the "Tier Totals"in each K/A category shall not be less than two).324333. Generic Knowledge and AbilitiesCategories103361227Systems/evolutions within each group are identified on the associated outline; systems or evolutions that do not applyat the facility should be deleted and justified; operationally important, site-specific systems that are not includedon the outline should be added. Refer to Section D.1.b of ES-401 for guidance regarding the eliminationof inappropriate K/A statements.The point total for each group and tier in the proposed outline must match that specified in the table.The final point total for each group and tier may deviate by +/-1 from that specified in the table based on NRC revisions. The final ROexam must total 75 points and the SRO-only exam must total 25 points.Revision 2 Revision 2ES-4012Form ES-401-2ES-401PWR Examination OutlineForm ES-401-2Emergency and Abnormal Plant Evolutions - Tier 1/Group 1 (RO)E/APE # / Name / Safety FunctionK1K2K3A1A2GK/A Topic(s)IR#000007 Reactor Trip / 1CE/E02 Reactor Trip Recovery / 103Annunciators and conditions indicating signals, and remedialactions associated with the (Reactor Trip Recovery).3.0000008 Pressurizer Vapor Space Accident / 330Inadequate core cooling4.31000009 Small Break LOCA / 30000011 Large Break LOCA / 301.20Ability to interpret and execute procedure steps.4.61000015 RCP Malfunctions / 4000017 RCP Malfunctions (Loss of RC Flow) / 401Natural circulation in a nuclear reactor power plant4.41000022 Loss of Rx Coolant Makeup / 203Relationship between charging flow and PZR level3.01000025 Loss of RHR System / 403LPI pumps3.41000026 Loss of Component Cooling Water / 802The automatic actions (alignments) within the CCWS resultingfrom the actuation of the ESFAS3.61000027 Pressurizer Pressure Control SystemMalfunction / 303Controllers and positioners2.61000029 ATWS / 112M/G set power supply and reactor trip breakers4.11000038 Steam Gen.

The ATC will report thatthe letdown heat exchanger temperature is reading high on the hand indicating controller but thecomputer point and control board indication are reading lower than normal due to excessive coolingflow. The SRO will direct the ATC to take manual control of the Letdown heat exchangertemperature control valve and manually control temperature for the duration of the scenario.After the letdown temperature controller has been placed in manual and cued by the lead examiner,2VSF-1D containment cooler will trip. The BOP will determine that 2VSF-1D containment coolerhas tripped and refer to OP-2203.012D/E, 2K04 and 2K05 Annunciator Corrective Actions. TheBOP will start the idle containment cooler to maintain containment temperature and pressure in theacceptable region of operation. The SRO will enter Tech Spec 3.6.2.3 Action a.

The CRS will enter OP-2203.025, RCP Emergencies AOP. The crewwill monitor the 'A' RCP oil level trend and bearing temperatures. After bearing temperaturesbegin to rise (trip criteria >180F/min.) the ATC should trip the reactor and secure the 'A' RCP. Thecrew may elect to secure a RCP in the 'B' S/G loop to balance flows. Securing a RCP notsatisfying operating limits is a time critical operator action per OP-1015.050 Time Critical OperatorAction Program.

After the reactortrips a Main Steam line break ('B' SG) inside containment will cause an Excess Steam Demand.Main Steam Isolation (MSIS) and Containment Spray (CSAS) will actuate tripping Main Feedwaterpumps, Condensate pumps, AFW pump, closing the MSIVs and feedwater block valves. The 2P-7B EFW pump motor will fail to start and 2P-7A EFW pump coupling will break causing a loss offeedwater event. The ATC will secure all the Reactor Coolant pumps due to the ContainmentSpray actuation. When the 'B' RCP spray valve (2CV-4652) handswitch is placed in manual, thevalve will fail open. The ATC must recognize this and isolate the spray valve using the associatedblock valve. If the spray valve is not isolated, the ATC's ability to control RCS pressure will belimited.

Appendix D Scenario 3Form ES-D-1Revision 3Page 3 of 44SCENARIO #3 NARRATIVESimulator session begins with the plant at ~98% power.When the crew has completed their control room walk down and brief, they will shift runningvacuum pumps.When the vacuum pumps have been shifted or when cued by the lead examiner, the Reactor Regpressurizer level program output will fail to minimum (41%). The SRO will enter the OP-2203.028, PZR System Malfunctions AOP. The ATC will take manual control of letdown tocontrol pressurizer level. The ATC must take control of PZR heaters to control RCS pressure (Allheaters will be energized) The ATC should place the PZR level controller to Auto and Local thenadjust the setpoint to programmed setpoint. Then Letdown should be placed back in automatic.This failure will also prevent manual start of back up charging pumps if needed to control PZRlevel.When letdown has been restored to automatic or cued by lead examiner, the in-service ContainmentAir Monitor System (CAMS) unit 2RITS-8271-2 coupling will fail. The ATC should report the2K-11 H10 CNTMT Air Monitor trouble alarm and refer to the ACA. The BOP should investigateand determine that 2RITS-8271-2 has low flow. When contacted, the NLO will report the couplinghas failed. The BOP should use OP-2104.033 Ventilation System Operations to place the standbyCAMS unit in service. When the standby CAMS unit is placed in service, the particulate detectorwill fail requiring entry into Tech Spec 3.4.6.1 Action a. [Site OE: CR-ANO-2-2013-1880, CAMSparticulate detector failure, CR-ANO-2-2011-2691, for CAMS unit low air flow and CR-ANO-2-2006-1191, for sample motor failure.]When all actions due to the CAMS failure have been completed, or cued by the lead examiner, 'B'MFWP will trip. The SRO will enter and implement OP-2203.027, Loss of Main Feedwater PumpAOP. This will result in steam flow exceeding feed flow and SG levels lowering. The crew willmanually and rapidly reduce turbine load, insert group 6 and group P CEAs, borate usingemergency boration to the RCS until feed flow is greater than steam flow. The SRO will berequired to enter Tech Spec 3.2.6 for Tc out of range high. Then start a normal boration powerreduction to less than 80%. [Industry OE: INPO event # OE31445 Loss of a Main feedwater pump.Site OE: CR-ANO-2-2009-3744, 'B' Main Feedwater pump trip.]After the crew has restored feedwater flow greater than steam flow or cued by lead examiner, aSteam Generator Tube Leak will occur on 'B' Steam Generator. The SRO will enter OP 2203.038,Primary to Secondary Leakage AOP. The SRO should enter TS 3.4.6.2 Action a, RCS leakage, andTS 3.7.1.2 for EFW when steam is isolated to 2P-7A EFW pump. When the leak rate exceeds 44gpm, the crew should determine that the leak rate is greater than 44 gpm. They will trip the reactor,actuate SIAS, and CCAS.

Appendix D Scenario 3Form ES-D-1Revision 3Page 4 of 44SCENARIO #3 NARRATIVE (continued)The Crew will implement OP-2202.001, Standard Post Trip Actions (SPTA) EOP. When SIAS isactuated the Green train components will fail to reposition. The crew should recognize the failureof Green train SIAS to actuate. The BOP should have a NLO check the breaker and pump motorsfor the Green train High Pressure Safety Injection (HPSI) and Low Pressure Safety Injection pumps(LPSI) pumps. After the NLO report, the BOP should manually start 2P-89B HPSI pump and openall injection valves. Also, 2CV-4821-1 Red train letdown isolation valve will fail to close leavingletdown aligned. The ATC should recognize that letdown is aligned and close a Green trainisolation to help maintain RCS inventory. The crew will align Service Water to CCW to maintainforced circulation. The crew may lower Steam Dump Master Controller setpoint during SPTAs toaid in maintaining margin to saturation. [Industry OE: SOER 83-9, Valve inoperability cause bymotor operator failures for 2CV-4821-1.]The SRO will diagnose and enter OP-2202.004, Steam Generator Tube Rupture (SGTR) EOP. TheATC should commence cool down of the RCS to allow isolation of 'B' steam generator. The BOPwill override Service Water to Auxiliary Cooling Water to maintain condenser vacuum. During thecooldown, 2CV-0303, 2CV-0302, or 2CV-0306 Steam dump valve (depending on which is beingused) will fail closed impacting the cooldown rate. The ATC will notice that the cooldown hasstopped and adjust the cooldown rate to ensure the steam generator is isolated within the 30 minuterequired time. Once Thot is less than 535 degrees F, the BOP should isolate 'B' steam generator.[Site OE: CR-ANO 2010-558, CR-ANO 2009-3780, CR-ANO 2008-1190, Steam dumpvalve failure to open.]
