Tab 8 EP-PS-244-8 METNENT DATA ACQUISITION OPTIONS The following are sources of meteorological and ventilation data at Susquehanna SES:

A. ACQUISITION OF METNENT DATA FROM THE PICSY TERMINAL

1. From the SSES LOGO display, select E-PLAN MENU or type EPM and [ENTER].
2. All required meteorological and ventilation (METNENT) inputs for the MIDAS dose projections can be obtained by selecting the METNENT DATA display option on the E-PLAN menu.
a. Vent and Primary Met Tower Data is displayed on page 1 of this display.
b. Use the PAGE FORWARD command if the Back-up Tower data is required.
c. Should neither the Primary or Back-up Tower be available, obtain the Downriver Tower data as follows:
1) At the command line, type GDVMS05B and [ENTER] for Downriver Tower wind speed.
2) At the command line, type GDVMX09B and [ENTER] for Downriver Tower wind direction.
3) At the command line, type GDVMX1 OB and [ENTER] for Downriver Tower sigma theta.
4) Press Escape [ESC] to return to the SSES Logo display.
d. Other options - see Step 6 below.
3. Ifthe 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.

4. The PICSY QUALITY CODES for the display colors are as follows:

YELLOW: DATA ACCEPTABLE RED: DATA EXCEEDS WARNING LIMIT MAGENTA: DATA EXCEEDS ALARM SETPOINT WHITE: DATA SUSPECT

5. If a hard copy printout of the information is required you may either:
a. Select the PRINT option using the pull down menu (screen copy takes approximately 3 minutes to complete); or
b. Initiate the METNENT 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 [ENTER].

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

6. If historical METNENT information is required, refer to the following instructions:
a. At the command line, type: GD.AMETVENT1 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.

c. The work file name to be used is ARCHIVE.D, which is the default for that field.
d. Enter the desired retrieval time. Click on OK.
e. Group point display will return with values for the specified retrieval time.
f. Press the [F4] key to step through data points from the specified retrieval time to the current time.

NOTE: Not all desired data is likely to be available for any one particular point in time.

Tab 8 EP-PS-244-8

g. Press the [F4] key if you want to step slowly through the data. Press the [F5] key if you want to step quickly through the data. (See bottom of screen for F key menu for more options.)
h. The group point display will return to real time when history is complete. A message at the top of the screen will alert you that it is returning to real time.
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 Manager's name, phone number and mailing address are as follows:

ABS Consulting Mark Abrams (301) 907-9100 (301) 921-2362 (Fax)

ABS Consulting Suite 200 4 Research Place Rockville, MD 20850

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.

The role of the local NWS office is to provide weather information and forecasts in support of emergency response activities at SSES. The NWS can be consulted over the telephone if data interpretations, assessment, or forecasting assistance are needed.

This information will include the following:

b. Precipitation rate in inches per 15 minutes, and,
c. Boundary layer atmospheric stability described as STABLE, UNSTABLE, or NEUTRAL.
  • Estimates of current 10-meter and 60-meter wind speed and wind direction in the event of complete loss of onsite and offsite meteorological instrumentation.

  • Periodic weather updates at time intervals dictated by the on-going weather and emergency situation.

NOTE: The NWS should ONLY be contacted when meteorological support from ABS Consulting is not available (i.e., weekends, holidays, and during the overnight hours).

Whenever contacting the NWS, be sure to provide the following information:

  • Name, Title, Facility, and Location
  • Reason for the call
  • Status of the Emergency
