These differences meet the NUREG

malfunction will be added post trip that has
not been used in any scenario on the last 2
NRC exams. This will give this scenario 4
events not on a previous scenario in the

address the Containment safety function.
This was not part of either of the last 2
exams.
In the 2018 exam, the LOCA included a loss
of all Low Pressure Injection Pumps and the
crew had to align a Containment Spray
Pump to address that safety function. The
crew did enter OP-902-008, the Functional
Recovery, but it was due to a loss of all low
pressure injection.
Attachment 6 OBDI 202 - IOLE Process Rev 3
In the 2017 exam, The LOCA was followed
by an excess steam demand event. The
crew did enter OP-902-008, the Functional
Recovery, but it was due to having 2
separate events in progress.
In addition to different entry conditions each
exam, verified that the SRO prioritization
after entering OP-902-008 was different in all
3 exams.
Scenario 3. For 2020, the major event is a
Loss of Offsite power and a failure of the
remaining diesel output breaker to close
because of the voltage regulator failing low
requiring operators to raise voltage manually.
For 2018, a loss of offsite power occurred
and the remaining EDG output breaker did
not auto close because the 3 to 2 tie breaker
did not auto open on under voltage requiring
the operator to manually open the 3 to 2 tie
breaker.
Scenario 4- The major is a Steam Generator
Tube rupture. The subsequent malfunction
on the 2020 NRC exam is a failure of a
Charging Pump to start. The subsequent
event on the 2018 NRC exam following the
Steam Generator Tube Rupture is a failure of
a HPSI pump to auto start.
The initial conditions for all scenarios were
different for the major that were overlapped
in the previous two exams.
Per the NUREG, if major is repeated from
any of the previous two exams, the author
should change the major event, the IC, or
subsequent malfunction to alter the course of
action.
This outline meets the requirement of the
NUREG for overlap of the major events.
For events, at least two events in each of the
four scenarios have not been used on the
previous two NRC exams; no scenarios were
used from the W3 bank. This requirement
being met is explained in the comments
above for each scenario.
