However,- the onsite emergency response organization failed to demonstrate
proficiency in recognizing and classifying emergency conditions as listed
-in the_EAL matrix.
Specifically, the exercise controllers prompted the
Site _ Area Emergency declaration when exercise participants failed to
promptly declare a SAE based on greater than 50 mR/hr at the site boundary
for greater than 30 minutes.
This failure to fully meet the exercise
objective' of demonstrating an understanding of EALs and proficiency in
recognizing and classifying emergency conditions.in the TSC was noted as
an exercise weakness (Corrective action to this finding will be tracked by
IFI 50-302/88-15-01).
No violations or deviations were identified.
6.
Notification Methods And Procedures (82301)
This area was observed to assure that procedures were established for
notification of State and local response organizations and emergency
personnel by the licensee, and that the content of initial and followup
messages to response organizations were established.
This area was
further observed to assure that means to provide early notification to the
populace within t% plume exposure pathway were established pursuant to
10 CFR 50.47(b)(5), Paragraph IV.D of Appendix E to 10 CFR 50, and

The inspector observed that notification methods and procedures were
established and available for use in providing information regarding the
simulated emergency conditions to Federal, State, and local response
organizations, and to alert the licensee's augmented emergency response
organization. Notification to the State of Florida and designated of fsite
organizations appeared to be made in accordance with procedures with the
following exceptions:
(1) the Alert notification to the State Warning
Point was not initiated until 17 minutes after the Alert; (2) the
Emergency Coordinator did not review all notification messages; and
(3) State Notification forms for the Site Area Emergency were not
completoly filled cut (i.e. time and person notified was missing).
Corrective action to these findings will be tracked by IFI

by 10 CFR 50.47(b)(9), Paragraph IV.B of Appendix E to 10 CFR 50, and
specific guidance promulgated in Section II.I of NUREG-0654.
The accident assessment program included an engineering assessment of
plant status, and an assessment of radiological hazards to onsite and
offsite personnel resulting from the accident. During the exercise it was
noted by the inspector that timely and correct offsite dose projection
data was not available in the E0F.
The licensee also noted in their
critique that dose assessment data was not available on a timely basis.
The NRC inspection identified these observations as a significant concern
that required early corrective action.
In a brief meeting held after the
formal exit interview, the licensee committed to an increased dose
assessment training effort followed by a mini drill of the dose assessment
portion of the emergency organization.

1988 ANNUAL RADIOLOGICAL EMERGENCY RESPONSE PLAN EXERCISE
PURPOSE
The purpose of this Exercise is twofold:
to test the state of
emergency prepa' redness of Crystal River Unit 3 (CR-3), the Florida
Power Corporation (FPC) Corporate Emergency Response Organization,
and the State and local response organizations; and to meet the
annual Exercise requirement for licensees as. defined in 10CFR50,
Appendix E.
SCOPE
The Exercise will be a "partial participation exercise."
The
State's Division of Emergency Management (DEM) and Department of
Health and Rehabilitative Services (DHRS) will participate only to
the degree necessary to test directi6n and control functions.
The
State will provide a limited staff in the State's Emergency
Operations Center and at FPC's Emergency Operations Facility.
The
response organizations of the risk counties will participate
fully.
The Exercise will simulate events that will initiate a minimum of
three of the four emergency classifications.
The Exercise will'be conducted in a manner that simulates actual
,
emergency conditions as close.'.y as possible,
~
,
.
Throughout the Exercise events may be scheduled such that two or
more drills may be conducted simaltaneously.
Implementation will occur via Message Cards that will be provided
to Exercise participants by Implementors.
The Message Cards will
contain information that will require the participants to evaluate
conditions and initiate specific emergency responses.
Incorrect
response, or failure to respond within a reasonable time, will be
corrected.
The correction will be provided both as on-the-spot
training, and as a method for keeping the Exercise on schedule.
All corrections and prompts will be documented.
The Exercise will be formerly critiqued by participants and
Implementor / Evaluators.
The purpose of this critique will be to
evaluate the performance of response organizations, and to
determine the degree to which exercise objectives were met.

An ambulance
is requested and dispatched. Seven Rivers hospital is
notified.
0527 A work crew that evacuated the Auxiliary Building due to the
fire left an improperly installed hoist in place in the waste
gas valve alley on 95' elev.
The hoist causes a failure of a
waste gas header line resulting in a small crack and a
release of activity into the Auxiliary Building. The source
of the leak is the Waste Gas Decay Tank (WGDT) and cannot be
isolated.

NRC authorities are notified. TSC activation begins and the
Environmental Survey Team and Dose Assessment Team prepara to
activate.
0625 The TSC is staffed and operational and the release continues
from the WGDT.
,
0630 The Emergency Coordinator receives follow-up information
concerning the accident victims.
The first victim is good
condition but is being held for observation (mild smoke
inhalation), the second victim is in critical condition and
is being airlifted to Tampa Burn Center.
0635 A SITE AREA EMERGENCY is declared based on a dose rate of
>50 mr/hr for greater than 30 minutes at the Site Boundary.
State, local, and NRC authorities are notified and the EOF is
activated.
0645 WGDT pressure continues to decrease due to the leak thus
decreasing radioactive release rate through the plant vent
(RM-A2) to the environment.
0654 A Heater Drain Limit Switch shorts causing a reactor trip.
The turbine fails to trip and is tripped locally.
0657 The transient (Reactor Trip) causes a small break reactor
coolant system leak of 30 gpm in the Reactor Building.
0706 The control room receives a Reactor Building Sump alarm.
0715 RM-A2 is at normal levels (< Tech. Spec.) and WGDT pressure is
O psi thus terminating the release to the environment. The
RCS leak in the Reactor Building is now at ~48 gpm.

R/hr. Building spray is initiated and one pump fails due to a
failed Building Spray Valve (BSV-3). The Emergency Repair
Team is dispatched to the Auxiliary Building to investigate.
High RB pressure and operation of the Building Spray System
causes a failure of the penetration seal for the supply line
for RB Spray Ring No. 2 (l'ocated in quadrant 3,
106'elev., 8"
pipe). This causes the elevated RB activity to be released
into the Auxiliary Building.
0806 Control Room receives an RM-A2 HIGH alarm due to penetration
failure. Activity is again released to the environment.
0814 Reactor Building pressure is at 43 psig, RB temperature is at
