TAB 2 EP-PS-245-2 EMERGENCY CLASSIFICATION CHECK 0 1.0 TIMING OF CLASSIFICATION o 1.1 UNUSUAL EVENT An UNUSUAL EVENT shall be declared within 15 minutes of having information necessary to make a declaration.

o 1.2 ALERT An ALERT shall be declared within 15 minutes of having information necessary to make a declaration.

O 1.3 SITE AREA EMERGENCY A SITE AREA EMERGENCY shall be declared within 15 minutes of having information necessary to make a declaration.

. 1.4 GENERAL EMERGENCY A GENERAL EMERGENCY shall be declared within 15 minutes of having information necessary to make a declaration.

EP-AD-000-200, Revision 16, Page 1 of 39

TAB 2 EP-PS-245-2 CLASSIFICATION OF EMERGENCY CONDITIONS USE OF EMERGENCY CLASSIFICATION MATRIX NOTE: CONFIRM THAT INDICATORS AND/OR ALARMS REFLECT ACTUAL CONDITIONS PRIOR TO TAKING ACTION BASED ON THE INDICATOR OR ALARM.

The matrix is worded in a manner that assumes parameter values indicated are the actual conditions present in the plant.

The matrix is designed to make it possible to precisely classify an abnormal occurrence into the proper emergency classification based on detailed Emergency Action Level (EAL) descriptions. It is impossible to anticipate every abnormal occurrence.

Therefore, before classifying any abnormal occurrence based on the EALs in the matrix, one should verify that the general conditions prevalent in-plant and offsite meet the general class description of the emergency classification. In addition, prior to classification, one should be aware of the ramifications in-plant and particularly offsite of that classification. Special consideration of offsite consequences should be made prior to declaring a GENERAL EMERGENCY.

EP-AD-000-200, Revision 16, Page 2 of 39

TAB 2 EP-PS-245-2 POLICY STATEMENT ON EMERGENCY DECLARATIONS Policy When an emergency action level (EAL) is exceeded but the plant quickly returns below the EAL, the emergency should be declared. If appropriate, the emergency can also be downgraded or terminated at essentially the same time and the Emergency Notification Form can say the emergency was declared and terminated (or downgraded) minutes later.

Example The main steam lines isolate on high radiation due to a large oil intrusion into the vessel. The isolation on high radiation is a trigger to declare an Alert. If it can quickly be determined that the cause was not damage to the fuel and we should not be in an Alert, then the Alert should be declared and terminated with the same notification report.

Basis Declaring the emergency will notify interested offsite personnel and will demonstrate that we recognize that we exceeded an EAL. Immediately terminating or downgrading will avoid activation of company and offsite facilities that are not required for this event.

EP-AD-000-200, Revision 16, Page 3 of 39

TAB 2 EP-PS-245-2 CLASS DESCRIPTIONS UNUSUAL EVENT Events that are occurring or have occurred which indicate a potential degradation of the level of safety of the plant. No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.

ALERT Events that are occurring or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant. Any releases are expected to be limited to small fractions of the EPA Protective Action Guideline exposure levels.

SITE AREA EMERGENCY Events that are occurring or have occurred which involve actual or imminent major failures of plant functions needed for protection of the public. Any releases are not expected to exceed EPA Protective Action Guideline exposure levels except inside the emergency planning boundary.

GENERAL EMERGENCY - Events that are occurring or have occurred which involve actual or imminent substantial core degradation or melting with potential for loss of containment integrity. Expectation is that releases will exceed EPA Protective Action Guideline exposure levels beyond the emergency planning boundary.

1) Click on the E-PLAN MENU button at the top right hand corner of the METNENT DATA screen.

2) On the E-Plan menu select and click on the MET DATA screen.

3) Obtain the Downriver Tower wind speed (Point ID VMS05B), wind direction (Point IDVMX09B), and sigma theta (Point ID VMXlOB).

4) Return to the E-Plan menu by clicking on the E-PLAN MENU button at the bottom right hand corner of the MET DATA screen.

d. Other options - see Step 6 below.

3. If the Primary Met Tower AT data is not available, determine the wind speed corrected stability class as follows:

a. Determine the initial (uncorrected) stability class using the measured value of sigma theta and the Supplemental Meteorological Information Table 1 (or page 2 of the PICSY screen).

b. Determine the wind speed corrected stability classification using the initial classification, the measured wind speed, and, as appropriate, either Table 2 or Table 3.

a. Select the PRINT option using the pull down menu (screen copy takes approximately 3 minutes to complete); or

b. Initiate the MET/VENT DATA LOG option as follows:

1) On the E-PLAN menu, select the FREE FORMAT LOG MENU.

2) To activate the TSC log, press [Fl], [22], and [ENTER].

To activate the EOF log, press [Fl], [9], and [ENTER]..

NOTE: Be sure to read the log description because there are 2 logs for the TSC and 2 logs for the EOF.

3) The log will start printing at the next quarter hour.

4) To deactivate the TSC log, press [F3], [22], and [E.NTER].

To deactivate the EOF log, press [F3], [9], and [ENTER].

6. If historical MET/VENT information is required, refer to the following instructions:

a. At command line, type: GD ^METVENT1 and [ENTER].

b. Group point display for that display file will come up. Press the [F3] key for history. (See bottom of screen for F key menu.) A dialog box will appear.

6. To exit the menu, select the [ESC] key.

B. Site-specific meteorological information can be obtained by contacting either ABS Consulting or the National Weather Service (NWS).

1. ABS Consulting ABS Consulting is the primary meteorological contractor for the Susquehanna Steam Electric Station (SSES). ABS Consulting has the ability to interrogate the primary and backup meteorological towers on a real-time basis and provide short and long-term weather forecasts for the site and surrounding area.

ABS Consulting provides this emergency service to PPL ONLY during normal working hours. The SSES Project Managers name, phone number and mailing address are as follows:

2. NATIONAL WEATHER SERVICE The National Weather Service's (NWS) primary meteorological support responsibility for a radiological emergency at SSES resides with the NWS office at Binghamton, New York. In the event the Binghamton office is unable to provide this support, the designated backup is the NWS office in State College, Pennsylvania.
