1. Description of Change:

The table below provides a summary of the changes that are non-technical or editorial for clarification only and do not change the intent of the Emergency Plan.

STPEGS Emergency Plan Change ICN 20-22 No. Change Reason Section J.9, Exposure to Airborne Contamination The Emergency

1. Plan is being 4th bullet changed: updated to reflect the most recent FROM federal (FDA) guidance for the Potassium lodide should be issued to all onsite use of Kl for personnel on a voluntary basis at a General Emergency emergency or when dose projections onsite or survey results workers.

projected exceed twenty-five (25) rem Committed Dose Equivalent to the thyroid. The issuance shall be determined by the Emergency Director and Radiological Director.

TO Use of a thyroid-blocking agent (Potassium lodide (Kl))

may be authorized when the committed dose equivalent (CDE) to the thyroid of an emergency worker is estimated to exceed federal recommendations.

Considerations for authorizing Kl for emergency workers are provided in Emergency Response Procedure OERP01-ZV-IN10, Administration of Potassium lodide.

The Emergency Director has the responsibility for approval of issuing Kl to site emergency workers.

Attachment 2, Implementing Procedures, added This is a new

2. procedure which OERP01-ZV-IN10, Administration of Potassium lodide governs the station's use of Potassium lodide.
2. Eva I uation Summary of Change:

The STPEGS Emergency Plan, as changed, continues to make available a range of protective actions for plant emergency workers during emergencies, including the use of the radioprotective drug Potassium lodide (Kl). This change does not affect the type, quantity, availability, or assignment of responsibilities related to the administration of Kl at STPEGS; STI:34887668

NOC-AE-19003678 Enclosure 1 Page 2 of 2 therefore, the resources provided for controlling radiological exposures for emergency workers remain unchanged.

Specific to Kl, a new implementing procedure, OERP01-ZV-IN10, "Administration of Potassium lodide" has been created to consolidate the latest federal guidance on the safe and effective use of Kl to prevent or reduce the uptake of radioiodine by the thyroid gland.

The committed dose equivalent (CDE) dose threshold is being changed to reflect the updated federal guidance as presented in Food and Drug Administration (FDA) Center for Drug Evaluation and Research Guidance, "Potassium lodide as a Thyroid Blocking Agent in Radiation Emergencies," dated December 2001. This FDA guidance is referenced in the updated EPA PAG Manual EPA-400/R-17/001, "PAG Manual: Protective Action Guides and Planning Guidance for Radiological Incidents," dated January 2017, and provides a new technical basis for the safe and effective use of Kl as an adjunct to other protective measures against inhaled radioiodines for protection of emergency workers.

This change does remove a General Emergency declaration as a basis for consideration of Kl use, but now makes the recommendation and approval of Kl issuance subject only to estimated CDE doses which will exceed federal recommendations as provided in Table 1 of implementing procedure OERP01-ZV-IN10. This change reflects the methodology of the latest federal guidance and is based only on estimated CDE dose and not on plant conditions which

  • may or may not present an airborne radioiodine exposure risk.

Additionally, ingestion of Kl by individual emergency workers is unchanged and remains voluntary.

3. 10 CFR 50.54(a) Summary of Analysis Evaluation of Change:

The changes have been evaluated and the determination made that:

  • The change does not reduce the effectiveness of the emergency plan or its implementing procedures. The Emergency Plan as changed does not reduce the capability of the STPEGS Emergency Response Organization to perform any emergency planning function.
  • The change continues to comply with Appendix E to 10 CFR 50Emergency Planning and Preparedness for Production and Utilization Facilities requirements.
  • The change continues to meet the elements identified by NUREG-0654/FEMA-REP-1, Rev. 1, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in support of Nuclear Power Plants.

Based upon the evaluation, the changes do not represent a Reduction in Effectiveness of the Emergency Plan.

Enclosure 2 South Texas Project Electric Generating Station Emergency Plan Section J and Attachment 2 STI:34887668

SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION EMERGENCY PLAN SECTION J J RADIOLOGICAL EXPOSURE CONTROL Management commitment for an effective Dose Control Program (As Low As Reasonably Achievable) necessitates that detailed radiation protection measures be established and utilized during emergency situations as well as nonnal operating periods at the Station. These measures are described in Emergency Response Procedure OERP01-ZV-IN06, Radiological Exposure Guidelines. A description of applicable radiation control measures are outlined in this section.

J. 1 Personnel Exposure Monitoring The approved Station Radiation Protection Procedures provide the specific actions undertaken to determine and record individual occupational exposures on a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day basis.

The Radiological Director or his designee is responsible to ensure that all personnel entering the Station, including visitors, vendors, contractors, construction personnel, and employees, are properly monitored for exposure to ionizing radiation.

Allowable planned emergency exposures and accident exposures to individuals have been established by the Nuclear Regulatory Commission and the Environmental Protection Agency. In all cases and events, administrative control and restriction of exposure to radiation will be monitored by the radiation protection staff in accordance with OERP01-ZV-IN06, Radiological Exposure Guidelines.

J. 1.1 Emergency Exposure Guidelines Environmental Protection Agency-400-R-92-001, Manual of Protective Action Guides and Protective Actions for Nuclear Incidents, is used to establish additional exposure guidelines for lifesaving actions and protection of property.

J. 1.2 Emergency Exposure Limits All questions of radiation exposure limits for emergency workers above Code of Federal Regulations, Title 10, Part 20 limits will be directed to the Emergency Director. This individual has the nondelegable authority in an emergency to authorize volunteer emergency workers to receive exposures in excess of Code of Federal Regulations, Title 10, Part 20 limits. The methods of documenting the voluntary status of the workers are authorized in Emergency Response Procedure OERP01-ZV-IN06, Radiological Exposure Guidelines.

E-PLAN\SEC-J Page 1 of 8 Revision 20 05/01/02

SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION EMERGENCY PLAN SECTION J J.2 Measurement of Radiation Worker Exposure Twenty-four hour per day capabilities have been established for determining the exposure received by workers by utilization of the Radiation Protection staff. Radiation Protection personnel, under the guidance of the Radiological Manager, will issue dosimetry and maintain logs of activities. The Radiological Manager ensures the Emergency Director and Radiological Director are kept informed of the exposure of emergency responders.

J.3 Contamination Control and Preventive Measures Preventive measures will be taken to minimize direct exposure to or ingestion of radioactive materials. This will include timely processing of all solid, liquid, and gaseous wastes using the Station radioactive waste processing systems in accordance with established plant procedures or other waste processing systems as necessary. Other contamination control measures are described in detail in the Station's Radiation Protection Program, the Emergency Response Procedures, and are summarized as follows:

In order to avoid personnel contamination or the spread of contamination in the Station areas, contaminated areas will be designated and clearly identified. Access to these areas will be controlled and appropriate protective clothing will be specified to minimize personnel contamination and the spread of contamination. Limits for the use of protective clothing are specified in the Station Radiation Protection Procedures. Personnel and equipment leaving the controlled area are monitored to assure that the limits for contamination control are met. If personnel become contaminated. Station Radiation Protection operating procedures will be implemented.

In general, contaminated areas and materials are permitted to return to normal use when areas meet the Station Radiation Protection Program contamination limits. Some areas and equipment may be returned to service prior to achieving these limits. In such cases, special precautions and measures are taken to prevent personnel contamination and to limit the spread of contamination.

J.4 Drinking Water and Food Contamination Control Drinking water and food supplies are not allowed in contaminated or potentially contaminated areas. If the potential exists for food or water to become contaminated in normally clean areas, Radiation Protection personnel will perform appropriate surveys and sample analysis, respectively.

E-PLAN\SEC-J Page 2 of 8 Revision 20 05/01/02

SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION EMERGENCY PLAN SECTION J If contamination is found, appropriate actions will be taken based on the levels of contamination and its location.

J.4.1 Surveys of Emergency Response Facilities Radiological surveys of the emergency response facilities and the assembly area for habitability will be performed on a frequent basis. These surveys will include radiation levels and contamination and airborne radioactivity concentrations.

Drinking, smoking, and eating are prohibited during a radiological incident in areas where the potential for contamination exists.

J.4.2 Airborne Releases In the event of an airborne release of radioactive materials, samples will be collected by Station personnel, and State and other agencies. These samples are analyzed and the results recorded and reported to the Emergency Director and the Department of State Health Services for appropriate offsite protective action recommendation decisions.

J.4.3 Colorado River & Selected Wells Selected wells are analyzed for radioactivity as part of the Radiological Environmental Monitoring Program at the Station. Surface water from the Colorado River is sampled at several locations upstream and downstream of the Station's river discharge. These samples are analyzed for gross activity as part of the Radiological Environmental Monitoring Program.

J.5 Radiological Medical Considerations Responses to personnel injuries are in accordance with guidelines set forth in OPOP04-ZO-0004, Personnel Emergencies and OPGP03-ZA-0106, Emergency Medical Response Plan.

Normally, in the event a personnel injury occurs in a Radiologically Controlled Area and the person requires offsite medical aid, the person will be taken to the Radiologically Controlled Area Access Control Point. The person is monitored for contamination and, if found to be below the levels for personnel contamination, the person is treated as a normal industrial accident and first aid will be supplied by Station medical assistance personnel. If additional treatment is required, the Station shall transport the person to the Matagorda Regional Medical Center or Palacios Community Medical Center for treatment.

Transportation will be provided by the site with Station medical staff in attendance or a contractor ambulance service.

E-PLAN\SEC-J Page 3 of 8 Revision ICN 20-8 12/03/09

SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION EMERGENCY PLAN SECTION J J.5.1 Personnel Contamination In the event, the person is contaminated above the levels for personnel contamination, reasonable efforts will be made to decontaminate the person at the Radiologically Controlled Area Access Control Point. If this can not be done due to the nature of the injury and/or hospitalization is required immediately, medical treatment and transportation to the hospital will take priority. The person will be placed in clean protective clothing or wrapped in a clean blanket time permitting, to minimize the spread of contamination.

J.5,2 Health Physics Supervision A Radiation Protection Technician will accompany the individual to the hospital.

Health Physics Supervision should meet the person at the hospital. The medical facility will be notified when a contaminated patient is being transported for treatment to allow for establishment of the radiological treatment area.

J.5.3 Hospital Procedures When the victim arrives at the medical facility, the staff of the hospital will follow their procedures to handle this type of injury. Radiation Protection personnel will conduct surveys to ensure that contamination levels are kept to a minimum and will monitor for contamination until cleanup has been satisfactorily completed.

J.5.4 Contaminated Items Contaminated items belonging to the individuals will be returned to the Station for decontamination or disposal.

J.5.5 Radiological Surveys Radiation Protection personnel will perform radiological surveys and assist with establishing radiologically controlled area boundaries in the medical facilities.

J.6 Personnel Evacuation from Station

  • Personnel evacuated from the site due to a site evacuation shall go to an offsite Reception Center or home as determined by the Emergency Director.
