Nuclear Evacuation Procedures
Standard Operating Procedures (SOP)
This SOP is prepared according to the requisites outlined in Annex F of the Hood County Emergency Operations Plan.
II. To establish an effective evacuation capability for the schools in the Granbury Independent School District.
III. General Plan
Notification that an incident has occurred at the Comanche Peak Steam Electric Station will be sent to the Texas Department of Health, the Texas Department of Public Safety, and the Hood County Sheriff. The responsibility for the evacuation of designated portions of Hood County is assigned to the County Sheriff. The County Sheriff, when advised of areas to be evacuated, will notify the Granbury ISD Superintendent, who will be responsible for the evacuation of the affected schools.
IV. Procedures for Evacuation
A. To accomplish evacuation from designated schools, the Sheriff will establish roadblocks and assist in relocation of evacuees.
B. Schools will be evacuated by the following procedures:
- When the Superintendent receives notification of an incident at Comanche Peak and evacuation is advised, schools will be notified over the intercom system that the school will be evacuated.
- School buses will immediately be moved to the designated loading area. Students and staff will remain in the schoolrooms for protection against possible contamination from exposure to a nuclear release.
- When buses are in place, an announcement will be made over the intercom to evacuate the building and move quickly and orderly to the bus loading area.
- Teachers should elect two captains from their classes, one to lead the class from the building and the other to assist the teacher by assuring that all students are in line, then notifying the principal's office that the room is clear. The principal is responsible for assuring that these students are loaded on the bus.
- When the principal is assured that all of the students are clear of the building and loaded on buses or private cars, the buses and cars will move in convoy to their designated shelter.
- Teachers will ride on the buses and while en-route to the shelters will ensure all students are accounted for and have a student roster to provide to the shelter for registration. The principal or his/her designee will secure AGR card (or copies) and relocate to the appropriate shelter to aid in the processing and accounting of students.
- Upon arrival at the designated shelter, the teachers will assure that all students are registered in the shelter reception area.
V. Preparations for Emergency
A. The maintenance section will establish procedures for personnel to follow the buses with spare tires and tools.
B. Based on the number of students to be transported from each school, buses should be assigned to specific loading areas.
C. Students who are allowed to drive personal cars will pickup their cars at the first notification of evacuation and move to loading areas behind the buses and will accompany the buses to the shelter reception areas.
D. Students will not be released to parents or guardians once buses are loaded for evacuation. No children will be left at the school.
E. If the school has an AM radio, tune it to the EBS station for your area or to any local radio station and instructions will be given to you on prevailing conditions.

NOTIFICATION OF UNUSUAL EVENT
When officials at Comanche Peak issue a "Notification of Unusual Event":
This event classification indicates that some minor variation from the norm has occurred at the plant. This category of notification could be issued fairly frequently, since federal and industry standards of operation dictate that any variation be considered significant. Events in this category pose no immediate threat to anyone offsite or onsite. This notification will be issued to local governments in the area of the plant simply to advise them that some minor anomaly has been observed in the plant's operation, and to allow the local governments to be prepared in case the situation at the plant deteriorates to a more hazardous condition.
When officials at Comanche Peak issue an "Alert":
This event classification means that something has happened (or may happen) at the plant, which could cause a degradation of safety conditions at the plant. Incidents, which could generate an "alert", will pose no immediate threat to person offsite, and probably none to persons onsite. An example of an event in this category might be a fire, which threatens to damage one of the safety systems. Offsite local officials will be given an "alert" message to allow them to prepare for the possibility that the situation might worsen, and because the plant may need to call upon localities for assistance in some form.
SITE AREA EMERGENCY
When officials at Comanche Peak issue a "Site Area Emergency":
This notice signifies that something has occurred (or may not occur) at the plant, which involves possible failure of the systems necessary to protect the public offsite. It does not mean that there is an immediate threat to the public, or that such a threat will develop. Generally it indicates that some area of the plant site has a problem requiring an internal (company) response, such as the malfunction of a pump, or the threat of flooding from excess rainfall. While the offsite public is not threatened, onsite personnel may be facing a distinct threat of varying magnitude.
The local governments are given the "Site Area Emergency" notification to: 1) advise them that the plant is involved with an onsite emergency, and: 2) allow the localities time to prepare for the possibility that the situation may deteriorate.
When officials at Comanche Peak issue a "General Emergency":
This term indicates that events are in process or have occurred at the plant, which involve actual or imminent substantial damage of the reactor core (nuclear materials). In this instance there is a possibility that radioactive materials could be released from containment. While the offsite public may not be immediately threatened, events in this classification do pose a possible threat to the general public. As a rule, you may assume that personnel onsite are facing a distinct threat of some sort. A general emergency would usually be generated by one of two types of incident: 1) Either a set of circumstances that make possible release of large amounts of radioactivity in a short time, or: 2) the licensee's (company) loss of physical control of the facility, such as by terroristic intervention. Offsite local officials will be given a "General Emergency" message to allow them to prepare for large-scale response activities, in the event that the situation at the plant deteriorates. In this phase, local officials may be called upon to implement evacuation procedures, shelter procedures, and/or types of emergency protective measures.
