TAB 1 EP-PS-247-1 METIVENT DATA ACQUISITION OPTIONS The following are sources of meteorological and ventilation data at Susquehanna SES:
A. ACQUISITION OF METNENT DATA FROM THE PICSY TERMINAL
[ENTER].
- 2. All required meteorological and ventilation (METNENT) inputs for the MIDAS dose projections can be obtained by selecting the MET/VENT 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)
Click on the E-PLAN MENU button at the top right hand corner of the METNENT DATA screen.

- 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) 907-0050 (Fax)
ABS Consulting Suite 620 East 7315 Wisconsin Avenue Bethesda, MD 20814
- 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.
EP-AD-000-124, Revision 19, Page 3 of 8
TAB I EP-PS-247-1 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.

CHECK 0 1.0 Limits for EMERGENCY doses.
E0 1.1 An EMERGENCY DOSE AUTHORIZATION (see EMERGENCY EXPOSURE EXTENSIONS) may be granted in order to protect facilities, and or equipment to substantially limit the escape of radioactive effluents or control fires. The maximum planned doses are:
1.1.1 Whole body (TEDE)(1) dose shall not exceed 10 Rem.
1.1.2 Dose to any organ (CDE)(2), including the skin and extremity (SDE)(3),
shall not exceed 100 Rem.
1.1.3 Dose to the lens of the eye shall not exceed 30 Rem (LDE)(4).
0 1.2 An EMERGENCY dose authorization may be granted for life-saving actions or protection of large populations. The maximum doses are:
1.2.1 Planned whole body (TEDE)(1) doses shall not exceed 25 Rem.
1.2.2 Planned dose to any organ (CDE)(2), including skin and extremity doses, shall not exceed 250 Rem.
1.2.3 Dose to the lens of the eye shall not exceed 75 Rem (LDE)(4).
1.3 RARE situations may occur in which a dose GREATER THAN those specified in SECTION 1.2 above for emergency dose would be unavoidable to carry out a lifesaving operation or to avoid extensive exposure of large populations. It is not possible to prejudge the risk that one should be allowed to take to save lives of others, therefore no upper limit has been established.
(1) The sum of the Effective Dose Equivalent resulting from the exposure to external sources and the committed effective Dose Equivalent incurred from all significant inhalation pathways during the early phase.
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
(3) Shallow Dose Equivalent.
(4) Lens Dose Equivalent.

3.0 PROTECTIVE ACTIONS 0
3.1 Potassium Iodide 3.1.1 For emergency workers entering areas where a committed dose equivalent, (CDE)(2), to the thyroid from radioiodine could be 25 Rem or greater, the Consulting Radiological Physician should provide input concerning the administration and cessation of KI intake. (See Emergency Telephone Directory for telephone number.)
3.1.2 For thyroid exposures that are strongly expected to exceed 25 Rem, (CDE)(2), KI doses of 130 mg (100 mg - iodine) per day should be administered.
Unless the EMERGENCY DIRECTOR or RECOVERY MANAGER instructs personnel to do otherwise, the KI tablets should generally be taken as soon as possible after thyroid exposure exceeding 25 Rem (CDE)(2) is projected.
NOTE: Stable Iodine (KI) is most effective when administered immediately prior to exposure to radioiodine. Significant blockage of the thyroid dose can be provided by administration within one or two hours after uptake of radioiodine.

CHECK 0l 3.1.3 Onsite issuance of KI for iodine prophylaxis requires the approval of the EMERGENCY DIRECTOR. Issuance to EOF and FIELD EMERGENCY MONITORING/SAMPLING TEAM personnel requires the approval of the RECOVERY MANAGER when the EOF has relieved the TSC of emergency management activities. The EMERGENCY DIRECTOR will approve issuance prior to that time.
These approvals must be documented on the POTASSIUM IODIDE (KI) TRACKING FORM.
3.1.4 For an injured and/or contaminated worker sent to a hospital for treatment, the patient will be under the care of the attending physician.
As such, plant procedures no longer apply and KI issuance will be at the discretion of the attending physician. The physician can rely on a senior Health Physics Technician Level II or Health Physics Management to provide the in-plant radiological data on which to base their decision.
0 3.2 Protective measures should be implemented for EOF personnel at the direction of the DOSE ASSESSMENT SUPERVISOR.
0l 3.3. Exposures to members of local offsite support groups, (ambulance workers, fire fighters) shall not exceed 500 mrem (TEDE)(1) for the performance of support duties on the site of the Susquehanna SES.
4.0 EMERGENCY EXPOSURE NOTIFICATIONS AND A HEALTH CONSEQUENCE INVESTIGATION must be conducted for any emergency exposure as outlined in step 6 of the Emergency Exposure Extensions.

Review the following factors:
o Rescue personnel should be volunteers or professional rescuers.
O Other considerations being equal (e.g., skill, potential need for person on another mission) personnel above the age of 45 are preferred.
0 Rescue personnel should be familiar and briefed with the consequences of exposure.
O Women capable of reproduction should not take part in an effort requiring EMERGENCY exposure.
El Use of personnel with high lifetime cumulative exposure should be discouraged.
El All reasonable measures must be taken to control contamination and internal exposure.
El Exposure under these conditions shall be limited to once in a lifetime.
0l For exposures greater than 25 Rem whole body (TEDE), the persons undertaking any emergency operation in which the dose will exceed 25 Rem to the whole body (TEDE) should do so only on a voluntary basis and with full awareness of the risks involved, including the numerical levels of dose at which acute effects of radiation will be incurred and numerical estimates of the risk of delayed effects.
