Appendix D Scenario Outline Form ES-D-1 Facility: Fermi 2 Scenario No. 2 Op-Test No: 2018-1 Examiners: xxxx Operators: SRO-2 (CRS), SRO-1 (ATC), RO-1 (BOP) xxxx Surr (CRS), RO-3 (ATC), RO-2 (BOP) xxxx Initial Conditions: IC-182, MOC, 94% Rx. Power.

Turnover: The plant is operating at 94% following a rod pattern adjustment. Power is being held at 94%

pending an evaluation of thermal limits by Reactor Engineering. In the meantime, the plan for the shift is to swap divisions of CCHVAC for work on the Division 1 CCHVAC chiller. The operational checkout, and IV, for the D2 CCHVAC makeup radiation monitor is complete and in the Unit Log.

Critical Tasks: SC-SCRAM - With reactor at power and with a primary system discharging into the secondary containment MANUALLY SCRAM the reactor, before any area exceed the Maximum Safe Operating (MSO) levels); With a primary system discharging into the secondary containment and area radiation/temperature/water levels exceed maximum safe operating levels in more than one area, INITIATE Emergency Depressurization.

Event Malf. No. Event Event No. Type* Description 1 N/A N (BOP) BOP shifts from Division 1 to Division 2 CCHVAC.

N (SRO) 2 C51MF0006 I (ATC) APRM Flow Unit #2 fails upscale.

I (SRO) ATC bypasses APRM #2 and SRO evaluates LCO 3.3.1.1.

TS T41MF0004 C (BOP) Trip of Div 2 CCHVAC Return Air Fan. AOP 20.413.01 3 C (SRO) entry. BOP starts Div 2 CCHVAC. SRO evaluates LCO TS 3.7.3 and 3.7.4.

4 BBAZP603_ C (ATC) Swap of the running RRMG LO Pump due to noise (field A153NOISE C (SRO) report) and fluctuating amps.

5 N21MF0019 R (ATC) N. Condenser Pump Trips R (SRO) AOP 20.107.01 entry; ATC lowers power using Recirc. flow to 88%.

B21MF0103 M (ALL) RB Steam Tunnel Leak.

6 7 B21MF0015 C (BOP) MSIVs Fail to Isolate.

B21MF0054 C (SRO) Crew should attempt to isolate leak when area temp 160ºF EOPRF0033 (MNO). IF area temp is 200ºF and MSIVs are not closed, EOPRF0036 crew should manually close them. (MSL C MSIVs do not fully close.).

Reactor Manual Scram (Mode Switch to Shutdown) before RB Steam Tunnel Area temp reaches Max Safe Operating Temperature (MSO) of 210ºF. (CT)

Event Malf. No. Event Event No. Type* Description 8 E41MF0007 M (ALL) HPCI Steam Leak.

9 C (BOP) HPCI Fails to Isolate.

EOPRF0022 C (SRO) E4150-F002 Failure to Auto Isolate / E4150-F600 E41MF0001 Thermal Overload E41MF0008 Fire Alarm in the HPCI Quad; HPCI Area temp

>148ºF (MNO).

NOTE: 154ºF in HPCI area generates isolation signal.

E4150-F002 will not close, and E4150-F600 loses power. The leak cannot be isolated.

When Area Temperatures are >MSO (210ºF) in 2 areas, Emergency Depressurization is directed.

CRS directs BOP to open 5 SRVs (ADS preferred). (CT)

D. Reeser SRO-2 (CRS), RO-2 (ATC), Surr. (BOP)

Initial Conditions: IC-183, S/U, Rx Press at 700 psig, pulling control rods to raise RPV Pressure to 944 to 949 psig.

Turnover: The plant is in MODE 2 at ~4.5% CTP during a startup. RPV pressure is 700 psig with the N.

RFPT feeding via the SULCV, which is ~30% open. The S. RFPT has been warmed and speed brought back down to 1000 rpm.

Plans for the shift are to re-commence power ascension by withdrawing control rods.

Critical Tasks: RPV - Loss of Level - ED WHEN RPV water level cannot be determined, depressurize the RPV, ignoring cooldown rate; RPV - Loss of Level - FLOOD WHEN RPV water level cannot be determined, and RPV pressure is below the Minimum Steam Cooling Pressure (MSCP), inject into the RPV to FLOOD the RPV to the Main Steam Lines OR establish RPV pressure above the MSCP.
