CRYSTAL RIVER EMERGENCY PREPARI'.DNESS EXERCISE I
(Inspection Report #50-302/90-30)
September 27, 1990 A.
Name: John M. Will B.
Assionment: To observe the Control Room (CR) operators' ability to detect and classify an emergency, to make appropriate and timely notifications, and to take actions to mitigate and correct the casualties imposed by the exercise scenario.
C.
Site Personnel Contacted: J Stevenson, Lead Controller; E. Gallion, CR Controller; S. Chapin, Radiological Protection Controller, T. Miller, Shift Supervisor (SS); G. Sutter, Assistant Shift Supervisor; J Bech, Chief Nuclear Operator (offsite Com.); Gene Carr, Nuclear Operator; E. Lee, Nuclear Operator; L. Rutledge, Assistant helear Operator; T. Smith, Auxiliary Operator; S. Betts, Assistant Auxiliary Operator; P. Grimes, Clerk (Auxiliary Operator); P. Haines, Shift Technical Advisors; Bill Marshall, Accident Assessment (Operations Superintendent),
i G. Hebb, Technical Support Center (TSC) Operations Communicator (Off-shift SS;); C. Bennett, TSC-Operational Support Center (OSC) Communicator (OperationsPlanner).
D.
Positive Findinos Personnel demonstrated good use of repeat-back communications t
procedures.
Personnel at several stations were able to keep their stations effectively appraised of the status of the emergency through the intercept of walkie-talkie communications with field and emergency l'
0 l
J l
4 response teams. However, the one channel used for the exercise was quickly overloaded.
CR operators showed initiative in thinking ahead regarding potential i
1 events, such as evacuating personnel from possible plume effected areas; sources of water, should it be required, etc.
CR operators conducted a thorough review of Technical Specifications that would be effected by the sustained loss of offsite power.
CR personnel showed initiative in completing two EM-204(A) manual dose projection calculations prior to the activation of the TechnicalSupportCenter(TSC).
The operators showed' initiative which accelerated the backfeed procedure by using existing scaffolding in the area and by cutting rather than disconnecting the links.
l The operators conducted good discussions of alternatives, and the Operations Superintendent ensured that any proposed CR-generated actions were to be coordinated with the TSC.
The CR maintained an excellent detailed log of events.
E.
Neoative Findings The CR participating shift started the exercise somewhat augmer.ted with an auxiliary operator serving as clerk, an extra capability in a position that would not be filled during a back-shift emergency.
EM 202 Status:
When making the initial notification of an emergency condition to the l
NRC (Nuclear Regulatory Comission) and the State Warning Point, l
Tallahassee (SWPT), the highest emergency classification level.that i
2
?
a would have applied at any time prior to the call should first be declared.
i The notification chronology was:
0754 Unusual Event (CE) declared.
i 0804 Alert declared.
0808 States / counties notified of the UE.
l 0815 NRC notified of the Alert.
0825 States / counties notified of the Alert.
l Problems resulting were that 1) state / counties were informed of the-VE when the plant was in an Alert, 2) the NRC was informed of the Alertbeforethestateandcounties,and3)NRCwasneverinformedof the Notification of Unusual Event (NOVE).
The communicator started delivering his notification message of the Alert to the state / counties 21 minutes after the declaration and completed the message delivery 24 minutes after the declaration.
The State of Florida notification form does not require the signature of the Emergency Coordinator (EC) to release the message.
In the case of the Alert notification message, the communicator made three additions to the message after it.had been seen by the EC.
Reading the references listed below, it is not clear.if, during an emergency, the on-shift SS becomes the EC or the Acting EC.
In that responsibilities are described only for the EC, the title Acting EC
~
should be eliminated.

,u (c) Operation and staffing of the CR 3 Control Room During Emergency Classifications (EM-103).
The public address system was used to announce emergency classifications and evacuation instructions, but was not used to keep personnel informed of plant conditions such as the high-f radiation plane crash, loss of power, etc.
Extra participant badges should be provided to the CR for personnel who came in to become players (e.g., NRC Site Resident, Operations Superintendent, etc.
l Controller messages which inform a player of what he sees or observes should be shown to the player or read to him, but not left with him for later referral.
Exercise instructions refer alternately to Implementers, Evaluators, Controllers and Observers. Definitions of these titles need clarification.
F. Chronology Time Observation 0742 Walkie-talkie report from the Spent Fuel Area that there was a fuel handling problem and bubbles were corning from the pit.
