NEI 99-01, Rev. 4, "Methodology for Development of Emergency Action Levels," August 2000 DEFINITIONS Emergency Action Level (EAL):

A Plant specific system and/or effluent parameter values characteristic of a spectrum of off-normal conditions which, if exceeded, will initiate one of the two emergency classifications.

Event:

A category of EALs grouped according to plant systems or condition.

The magnitude of the event, as indicated by the EAL, dictates which class of emergency must be declared.

UNUSUAL EVENT:

Signifies events are in progress or have occurred which indicate a potential degradation of the level of safety at the plant.

ALERT:

An event which indicates an actual or potential substantial degradation in the level of safety to personnel on-site or to the safe containment of fuel.

Hurricane Warning:

An emergency category issued by the NWS indicating that sustained winds of 74 miles per hour or more are expected in a specified area in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or less.

DISCUSSION Attachment A provides a method to determine which event class is appropriate for the event(s) which is/are occurring.

In addition to specific Emergency Action Level (EALs),

nonplant-related events (e.g., aircraft crash on-site) are included.

If an event in progress requires assistance or additional resources, the Defueled Emergency Plan OP-3300 Rev.

21 may be implemented at the Shift Supervisor's discretion even though no EAL has been reached.

The methods of classifying an emergency include:

The use of specific plant instrumentation readings.

Review of system status.

Consideration of outside forces which could impact the plant.

Emergencies will be classified as one of the following:

UNUSUAL EVENT ALERT PRECAUTIONS None PREREQUISITES

1.

Perform this procedure concurrent with other emergency/operating procedures and operator actions which are in progress to mitigate and control the event(s) at hand.

PROCEDURE

1.

Identify the event category per Attachment A.

NOTE: When determining the class of the event, the EALs are to be used exclusively within the applicable event.

2.

Classify the event per Attachment A.

3.

Declare the most severe event class, consistent with the EAL that has been reached.

NOTE: Notification of off-site (state and federal) authorities is intended to be completed as soon as possible but within one hour.

This time is measured from the time at which operators declare an emergency.

4.

Once an event class has been determined, initiate OP-3315, Control Room Actions During an Emergency.

FINAL CONDITIONS

1.

An event has been classified and the Defueled Emergency Plan has been initiated as appropriate.

OR

2.

The event has been reclassified, if plant conditions have deteriorated/improved.

ALERT UNUSUAL EVENT III.

A fuel handling or component incident, resulting in radiation levels which indicate a degradation in the control of radioactive material, EAL A. Valid radiation monitor reading increases by a factor of 1000 over normal levels (Normal being the highest reading in the past 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> excluding the current peak value).
