Appendix D Scenario 2Form ES-D-1Revision 3Page 3 of 41SCENARIO #2 NARRATIVE (continued)When the Red Train Proportional Heater has been placed to auto or when cued by the leadexaminer, Channel B Excore upper chamber will fail high. The SRO will enter the OP-2203.026,NI Malfunction AOP and the crew should determine that B channel linear power is failed but logpower is still functional by monitoring output for the three chambers. The SRO will also enter TechSpec 3.3.1.1 Action 3 for Reactor Protection System. The BOP will trip points 1, 3, and 4 onchannel 'B' by using the linear calibrate switch. The points must be tripped because Channel C isin bypass.  [Site OE: CR-ANO-2-2002-693, D Excore failure.]When the SDBCS permissives have been aligned and cued by the lead examiner, the 'B' pressurizerpressure control channel will fail high causing the spray valves to open and RCS pressure to lower.The CRS should enter the OP-2203.028, Pressurizer System Malfunction AOP. The crew willplace the other pressurizer pressure controller in service, verify that both spray valves close, and thepressurizer heaters restore RCS pressure. The BOP will place a maximum of one Steam Dump andBypass Control System (SDBCS) valve permissive in manual and all other permissives to off.  [SiteOE: CR-ANO-2-2011-1605, Pressurizer pressure failing high.]After the BOP has tripped points 1, 3, and 4, and cued by lead examiner, 2P-33B CCW pump willtrip and 2P-33C CCW pump will fail to start automatically or manually. The SRO will enter OP-2203.025, RCP Emergencies AOP. The BOP should call NLOs to investigate the CCW pump trip.The SRO should direct the BOP to start 2P-33C CCW pump but it will fail to start. The SRO willthen direct opening all CCW cross-tie valves and start 2P-33A CCW pump.  [Site OE: CR-ANO-2-2007-313, Trip of 2P-33B CCW pump with 2P-33C out of service for maintenance.]After the crew has restored CCW flow to the RCPs, and cued by the lead examiner, a 15 gpm RCSto CCW leak will start. The crew should notice that CCW Surge Tank level is rising. The crew'srecognition of the leak may be delayed because the 'B' Surge Tank level would normally rise fromthe different pump configuration. Also the CCW letdown radiation monitor will alarm indicatingRCS to CCW leakage. The SRO will enter OP-2203.016, Excess RCS Leakage AOP, and directthe board operator actions. The crew should perform leak rates, isolate letdown to verify the leak isnot in letdown and determine the need for a plant shutdown using normal boration. The SROshould enter Attachment A of Excess RCS Leakage, align the CCW surge tanks to the gascollection header and direct the NLO to control surge tank level. The crew will perform a powerreduction such that the plant will be taken off line. The SRO should enter Tech Spec 3.4.6.2 Actiona for RCS leakage. The ATC will boratethe RCS and reduce turbine load to maintain Tave-Trefwithin 2&deg;F. The BOP will make preparations to remove secondary plant equipment from service aspower is reduced.  [Industry OE: NRC information notice 92-36 Intersystem LOCA outsidecontainment. Industry OE: SEN-220, SEN-216, & SEN-182, RCS leakage events.]After the required reactivity manipulations are complete and cued by the lead examiner, the RCS toCCW will degrade to 250 gpm. The SRO will direct the reactor to be tripped, actuate SIAS &CCAS, secure RCPs, and isolate CCW to the RCPs. The CCW to RCPs valves will fail to autoclose on a valid CIAS. The SRO should enter and direct the actions of SPTAs.

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.

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 topics must 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 totals for each category in the table above; if fuel handling equipment is sampled in other than Category A2 or G* on the SRO-only exam, enter it on the left side of Column A2 for Tier 2, Group 2 (Note #1 does not apply). Use duplicate pages 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 a second 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 RO and 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 Abilities Categories 103361227Systems/evolutions within each group are identified on the associated outline; systems or evolutions that do not apply at the facility should be deleted and justified; operationally important, site-specific systems that are not included on the outline should be added. Refer to Section D.1.b of ES-401 for guidance regarding the elimination of 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 RO exam must total 75 points and the SRO-only exam must total 25 points.

Appendix D Scenario 1Form ES-D-1Revision 3Page 3 of 51 SCENARIO #1 NARRATIVESimulator session begins with the plant at 100% power steady state.When the crew has completed their control room walk down and brief, the BOP will shift ControlElements Drive Mechanism (CEDM) fans from 2VSF-35D to 2VSF-35C.When the CEDM fans have been shifted or cued by lead examiner, the temperature input (2TE-4815) to the letdown heat exchanger temperature controller will fail high. 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. [Site OE: CR-ANO-2-2006-2444, 2VSF-1A motor failure and breaker trip.]After the BOP has started the idle containment cooling fan and cued by lead examiner, CEA 43 willdrop into the core due to faulty timing card. The SRO will enter OP-2203.003, CEA malfunctionAOP. The SRO should check that less than 2 CEAs are inserted and then commence a down powerwithin 15 minutes. The BOP should complete attachment C DNBR/LPD log. The SRO will enterTech Specs for CEA position (3.1.3.1 Action d) and Aztilt (3.2.3). [Site and industry OE: CR-ANO-2-2007-0127 dropped CEA, and NRC Event # 49601 Palo Verde dropped CEA.]After the crew has completed the required reactivity manipulation, entered the appropriate techspecs, and cued by the lead examiner, 'A' RCP oil leak will start that causes oil level to lower andbearing temperatures to rise. 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 >18 0F/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. [Site OE: RCP oil leaks CR-ANO-2-2013-1602, CR-ANO-2-2013-587, CR-ANO-2-2013-58.]The crew will implement OP-2202.001, Standard Post Trip Actions (SPTA) EOP. 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.
