• Palisades Plant Emergency Exercise Scenario - February 23, 1982 An emergency exercise is planned for the Palisades Plant for February 23, 1982.

The following action will be simulated:

At 0545 am Unusual Event will be declared due to high specific activity in the primary coolant system. Beginning the exercise before 0600 will fulfill the NUREG 0654 requirement of one exercise starting before 0600 every six years.

At 0700 the Shift Supervisor will begin shift augmentation. Although whift augmentation is not required in our emergency plan at this level, this action will provide an opportunity to test our shift autmentation ability as per NUREG 0654, Table B-1.

At 0800 specific activity in the primary coolant system will rise calling for an escalation to Alert be performed. As soon as each assembly area leader has accounted for his area, personnel not directly involved in the exercise will report back to work.

Personnel involved in the exercise will continue. Staff.to continue will be identified in advance and consist of the Technical Support Center staff and a portion of the Operations Support Center staff consisting of approximately one Radiation Safety Supervisor, ten Chemistry/Radiation Safety technicians, one Maintenance Supervisor and four Maintenance workers. The Emergency Operations Facility staffing and operation has been coordinated with the General Office.

At 0900 a turbine trip will occur. The main steam isolation valves will close and the atmospheric steam dump valves will open. One atmospheric dump valve will fail to seat after pressure lowers. At 0901 the reactor trips.

At 0915, steam generator tubes will repture. Radioactivity will be released to the atmosphere through the steam dump. A General Emergency will be declared. The release will be sufficient to require evacuation of the population out to three miles. A simu-lated evacuation will take place for non-essential personnel at the site due to high radiation levels.

At 1115 the release will end.

At 1200 the exercise will end.

The above scenario will test the following areas:

1. Notification and augmentation of the emergency organizations.

2. Communications

3. Emergency classification

4. Emergency actions

5. Protective action recommendations (1)

6. Decision making

7. Radiological monitoring, offsite and onsite.

8. Post accident sampling

9. Accountability Observer/Evaluators will be provided by General Physics, the General Office and the Midland Plant.

A critique is scheduled for 1330 until 1600 on 2/23/82. This critique will be organized by General Physics.

A final report, to be written by General Physics, is scheduled to be completed by 4/1/82.

The background information for the drill is as follows:

The plant has been operating at full power for the past month. No unusual conditions have been noted except as follows; the primary coolant activity has been slightly greater than 1.0 uCi/g dose equivalent I-131 for the past 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

The meteorological conditions are as follows:
