ExerciseScenario(82301)
The exercise scenario was reviewed and was found to be adequate to
demonstrate the objectives therein.
The objectives had been developed by
the licensee to demonstrate the adequacy of corrective actions taken in
response to exercise weaknesses identified during the December 17, 1986,
Annual Emergency Preparedness Exercise.
These weaknesses included a
delayed first aid response to a simulated medical emergency, an excessive
time period required for activation of the Technical Support Center (TSC)
,
and Emergency Operations Facility (E0F), and an incomplete information
flow from the Control Room to the TSC and from the Communicators to the
'
State and counties.
The scenario provided for a medical emergency and a
simulated accident which resulted in a General Emergency classification.
l
During the simulated accident the TSC and E0F were manned and participated
!
fully.
The Control Room participation was only a player / controller (one

The simulated patient was properly cared *,

30 minutes from the time of the accident.
Radiological monitoring

"
and contamination control techniques were observed during the medical
emergency.
The medical drill was successful and considered to be a
-
significant improvement over the December 17, 1986, drill in which
,
t
42 minutes elapsed from the time of discovery of the injured

individual to the time initial first-aid was provided.

The TSC was manned and activated 27 minutes after the Alert had been
declared. Command and control appeared to be effective and personnel
appeared aware of ongoing events and knowledgeable of their *
i
responsibilities as observed during the status briefings held by the
..
i
Site Emergency Coordinator.
The primary focus of the inspector's
observations following the TSC's activation centered on the
information flow from the Control Room and the notifications made r.o
e
the State and counties.
The receipt of information from the control C
.
. -~'
-
'-
Room was timely and accurate.
However, this information flow was an *
'
i
exercise artificiality since the Control Room personnel were not'
<
fully playing except for passing information and making
!
-
!
notifications.
During the licensee's criticue it was noted that
-
!-
personnel making notifications had signif' cant problems in
,
establishing the conference calls for making notifications.
The
-
r
4
licensee stated that this problem should be corrected with the
selective signaling feature being added to their telephones during
March 1987.
Notifications were adequate in that they were promptly
'
initiated and provided significant events and periodic status updates
,
to the State and counties.

Marrative summary
This scenario is based upon a medical emergency, a hydrogen leak'in a vital
area, failure of ,the reactor to trip on demand, fuel damage, and a loss of
,
coolant accident.
'
Initial conditions establish the Plant at 651 power. The Plant has reduced
power in order to perform OST-551 (Turbine Trip Functional Test) and scheduled
maintenance on "A" Main Feedwater Pump.
'
At the beginning of the scenario, a Chemistry Technician is found unconscious
by the ramp beside the RWST, apparently knocked out froh a fall due to an ice
accumulation on the ramp. Several containers from his sample hay have been
opened and spilled on the Chemistry Technician. An Und'sual Event should then
be declared due to " injured and contaminated personnel."
At 08:40, the condenser vacuum trip does not function correctly during the
performance of 087-551. A work request is generated, maintenance is notified,
and an I&C Technician is dispatched to investigate the problem.
At 08:45, a construction worker notifies the control room about a hydrogen
'
line rupture on the east side of the auxiliary building wall. Personnel are
dispatched from the control room and verify that the auxiliary building
,
hydrogen supply header is completely severed just above the intake for HVS-5A C
("A" Emergency Diesel Generator Room).
It was discovered that the CARDOX system has been actuated.
Shortly after the
line break is discovered, a hydrogen leak survey indicates levels of >100% LEL
outside the Emergency D/C room. An Alert should be declared at this time due
to " unplanned and uncontrolled entry of flammable or toxic gases into vital
areas in sufficient quantities to endanger personnel." An inspection of the
room will reveal that no fire exists.-
At around 10:30, the turbine trips due to a loss of condenser vacuum. The
lef t turbine stop valve and the left upper governor valve close switches do
not make, and a reactor trip signal is not generated. The operator will not
be able to initiate a manual reactor trip due to both reactor trip breakers
mechanically binding in the closed position. A Site Emergency will be
declared due to this ATWS condition. The EOP Network will be entered, and at
10:45 the reactor is successfully tripped outside the control room. During
the pressure transient, further fuel failure occurs, therefore, increasing
reactor coolant activity substantially. Also, during the pressure transient,
the pressuriser safety valves lift and relieve to the pressurizer relief tank
(PRT).

' Pressuriser relief valve RC-551'A does not fully ressat after the pressure
transient and continues to relieve to the PRT at a substantilat' rate. During
this same time, "B" sain feedwater pump trips due to HI-HI level in "A" steam
generator, and attempts to restart the pump will be unsuccessful. A Safety
Injection occurs at 11:05. Control board indications and radiation monitors
will confirm a loss of coolant accident and_ substantial fuel damage. When the
reactor fails to trip, a Site Emergency should be declared duai to " failure of
the reactor protection system to initiate and complete a trip which brings the
reactor to a subcritical condition as indicated by a valid trip signal
,
generated (manual or automatic) and reactor trip does not take place." The
event should be upgraded to a General. Emergency by approximately 11:45 due to
R-32 A/B >1,000 R/HR.
-
The PZR safety valve will fully ressat around 11:30, but only after the
rupture disks on the PRT have blown, releasing main coolant to containment
-steosphere. Containment radiation monitors will increase, and a dose
assessment will be made. Plant Operations staff will stabilise the Plant by
use of the Emergency Operating Procedures (EOPs). Recovery efforts will focus
on maintaining the Plant in a stable condition and r,estoring normal
