PURPOSE:
This Exercise is planned to test the s'. ate of emergency preparedness of Crystal River Unit 3 (CR #3), FPC Corporate emergency support organization, State of Florida, and local response organizations. In keepirg with the objectives of annual exercises, this test will provide a basis for individual familiarization with plans and procedures developed to manage emergency situations, as well as strengthen notification and professional interfaces among participating agencies. Following the events of the exercise, a formal critique will provide needed feed-back to resolve issues or problems identified during the mock emergency.
(1)
OB3ECTIVES:
Notification and Warning Verify the timeliness and adequacy of procedures and systems necessary for alerting and notification of off-site support agencies as well as Corporate Emergency response organizations.
Emergency Communications Test the adequacy and function of communication networks and systems among emergency response organizations as outlined in the Radiological Emergency Response Plan for Crystal River Unit 3.
Direction and Control Verify the adequacy of the Florida Power Corporation Emergency Plans and methods used in the implementing procedures and to assure that the participants are familiar with their respective duties and responsibilities.
Emergency Facilities and Equipment Verify the operability of emergency equipment and facilities as well as check the availability of emergency supplies.
Radiological Dose Assessment Test the methodology and implementing procedures for determining dose projections associated with release from the plant during emergency conditions. As a part of the dose l
assessment activities, the protective action recommendations will be evaluated for i
consistency and applicability.
Accident Assessment Test the overall performance of Florida Power Corporation's Emerec v;y Response Organization in the evaluation and mitigation of emergency situatio<
and recovery l
activities.
l l
Evaluation Provide the basis for evaluation of performance during simulated emergency operations in order to review and correct identified deficiencies in the Radiological Emergency Preparedness Program.
l l
(2) l l
SCOPES The exercise will involve all the emergency classifications by simulating events that will initiate each of the four emergency classifications.
This exercise shall be conducted, simulating as closely as possible, actual emergency conditions.
Throughout this exercise simulated conditions may be scheduled such that one or more drills may be held simultaneously.
Site evacuation will not include Units 1, 2, 4, & 5; however, they will be required to implement their personnel accountability procedures.
The exercise will be conducted in accordance with the pre-established scenario through a team of Implementors, Evaluators, Participants and Observers (See Section II, Definitions).
Tentative lists of Implementors / Evaluators and Observers are provided in Exhibits 1 and 2, respectively. The Implementors will initiate exercise activities according to Implementor Instructions, which may inturn provide Message Cards to Participants. (See Exhibits 3 & 4).
These Message Cards will contain information requiring the Participants to initiate specific emergency responses. Failure to respond or incorrect response will be corrected after a reasonable time to insure proper response and to keep the exercise on schedule. Evaluators, will assess and record the emergency response via Exercise Evaluation Forms (See Exhibit 5). Separate Observers may also be present.
A critique will be held to the exercise to document the implementation of the emergency plans and include appropriate evaluations and recommendations for corrective action.
Should events outside the control of the scenario or actual emergency conditions exist, the exercise will be terminated and appropriate steps taken to mitigate emergency situations.

III3 EXERCISE SCENARIO
Background
Crystal River Unit 3 has been operating at full power for 12 weeks with no significant problems. The reactor was shut down 2 weeks ago for refueling and a 10-year in-service inspection, which is currently ongoing.
During the in-service inspection, a loose part has been found in the reactor vessel. The decision has been made to remove the part through the fuel tube and the spent fuel pools.
The spent fuel pools contain fuel removed from the reactor for the inspection, as well as older spent fuel.
February 22,1983 TIME ACTIVITY / EVENT Unusual Event 1300 Work crew consisting of a Radiation Protection (R.P.) Technician, Mechanical Supervisor and ceveral mechanics is attempting to correct a malfunction in the Deboration Demineralizer System so that spent resin can be transferred.
During this repair effort, a piping connection breaks, spraying resin-slurry in a mechanic's face. The mechanic trips, falls, and is knocked unconscious.
1310 Control Room is notified, and First Aid Team is dispatched.
1315 A general radiation level of 10-20 mR/hr is measured.
1320 First Aid Team arrives at scene, calls Control Room to verify the injury, and reports the need for transport of the injured mechanic to a hospital. The victim's vital signs are as follows: BP - 110/60; pulse - 130/ weak; respiration -
28/ labored; pupils - slightly dilated. A radiation level of 750,000 dpm is measured on the victim's face, hair, and outer clothing.

TIME ACTIVITY / EVENT 1330 Control Room notifies plant emergency vehicle personnel and hospital and declares an " unusual event," in accordance with Implementing Procedure EM-202.
1335 Injured mechanic is made ready for transport by plant emergency vehicle (PEV).
1345 Injured mechanic is transported to hospital, with First Aid Team leader accompanying the PEV, in accordance with EM-213. (ETA Shands Hospital in Gainesville is 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br />).
1350 Remaining mechanics are contaminated at a level of 50,000 dpm on head and shoes.
1400 Decontamination of work crew begins, in accordance with Standard Plant Procedure RP-103.
1445 Decontamination of work crew is completed.
Alert Condition 1500 Smoke is detected in the Rad Waste Area (95 ft. level of Auxiliary Building) and reported to Control Room (CR) by an operator.
1510 CR notifies fire brigade.
1520 Fire brigade arrives in Rao Waste Area but is unable to locate fire immediately because of thick smoke.
1530 Fire brigade notifies CR of situation. CR declares an " alert" due to a fire duration of more than 10 minutes with the potential to affect safety-related systems.
Announcement of alert condition results in implementation of personnel accountability procedures, in accordance with EM-205.
(6)
TIME ACTIVITY / EVENT 1535 Fire brigade determines that the source of the smoke is a resin-slurry transfer pump which burned up as a result of being left on and running against a closed valve.
Site Emergency 1540 In preparation for removing the loose part found earlier, the missile shields have been removed from the spent fuel pools, and the pool divider gate is being lifted out of the water, using the jib crane and an electric hoist.
1545 Report is received in CR of one person not accounted for. Search Team is dispatched.
1605 Fire brigade notifies CR that fire is out and the only damage is the pump motor and the extensive water sprayed in the area. Clean-up commences.
1615 The pool divider gate is dropped into the spent fuel pool because of a failure in the lifting equipment. The R. P. Technician assigned to the work crew sees the gate strike fuel bundles in the pool and bubbles rise to the surface. The work crew evacuates the building and notifies the CR.
1625 The Spent Fuel Area Radiation Monitor (RM-GIS) alarms at its set point. The Fuel Handling and Spent Fuel Area Exhaust Duct Monitor (RM-A4) also alarms and is increasing. The Plant Vent Monitor (RM-A2) is also increasing rapidly.
