Title:

Emergency Exposure Levels / Protective Action Guides Page: 2 of 18 DESCRIPTION OF CHANGES Justification (required for major revision)

Clarification was required associated with the guidance for the issuance of Potassium Iodide. The procedure mentioned a name brand no longer in use at the site. The change supports the generic use of the term thyroid blocking agent instead of a name brand . Additionally, the most recent Kl received requires a dose of two tablets (65mg) each instead of the previous one tablet (130mg) .

Lastly, there was nothing in the procedure that addressed the basis for the number of Kl doses required during an emergency. Additional editorial changes were also completed . The changes are associated with AR-CR 00320600 Page(s) Description (including summary, reason, initiating document, if applicable) 7 Section 4.2.1.b. and 4.2.2.b., added Security Communications Center.

8 Section 4.2.5.b changed (State and County) to (State, Counties, and DOE-RL) for notification consistency.

Central Alarm Station. This was provided for clarification .

Added the following: The amount of thyroid blocking agent (Kl) maintained was determined as follows:

Identify the number of responding ERO personnel, double that number to represent two shifts, and multiply by 10 (10 day maximum dosage) to determine number of doses required.

NOTE: Number of dose boxes is dependent upon the number of doses contained in a box or package.

12 Attachment 7.3. Step C. changed THYRO BLOCK to thyroid blocking . Changed the first sentence to ... contains either 130mg or 65mg of potassium iodide (Kl) .

Change was made to support the receipt of a Kl product that is dispensed in 65mg tablets.

13 Modified Attachment 7.3. Step D.3. as follows: Only the TSC Manager and EOF Manager (or the Shift Manager acting as Emergency Director) can authorize the use of a thyroid blocking agent (Kl). The TSC Manager and EOF Manager (or the Shift Manager acting as Emergency Director) SHALL establish the extent and duration of the thyroid blocking agent (Kl) usage, based on radiological conditions and the advice of the Radiation Protection Manager or Radiological Emergency Manager, as appropriate. Removed reference to THYRO BLOCK, added thyroid blocking agent. Changes were made for clarification and consistency.

Emergency Exposure Levels / Protective Action Guides Page: 12 of 18 GUIDANCE FOR ADMIN ISTERING POTASSIUM IODIDE (Kl)

A. Purpose This attachment provides guidelines for recommending administration of potassium iodide (Kl) to all emergency workers both on and offsite as a thyroid-blocking agent to provide protection against airborne radioiodine .

B. Location of Kl Supplies

1. Control Room

2. Technical Support Center/ Operations Support Center

3. In-plant Emergency Equipment Cabinets

4. Emergency Operations Facility

5. Field Team Kits

6. Security Communication Center and Sweeper/Roadblock Kits in Protected Area Access Point (PAAP)

7. Central Alarm Station The amount of thyroid blocking agent (Kl) maintained was determined as follows :

Identify the number of responding ERO personnel , double that number to represent two shifts, and multiply by 10 (10 day maximum dosage) to determine number of doses required .

NOTE: Number of dose boxes is dependent upon the number of doses contained in a box or package.

C. Discussion Each thryoid blocking tablet contains either 130 mg or 65 mg of potassium iodide (Kl) . Certain forms of iodine help the thyroid gland work. The thyroid can "store" or hold only a certain amount of iodine. In a radiation emergency, radioactive iodine may be released in the air where it may be breathed or swallowed . It may enter the thyroid gland and damage it by overexposure. When potassium iodide is administered , it saturates the thyroid gland , thereby reducing the chance that harmful radioactive iodine will enter the thyroid gland.

Possible side effects include skin rashes, swelling of the salivary glands, and "iodism",

(metallic tastes , burning mouth and throat, sore teeth and gums , symptoms of a head cold ,

and sometimes upset stomach and diarrhea). A few people have an allergic reaction with more serious symptoms. These could be fever and joint pains, or swelling of parts of the face and body and at times, severe shortness of breath that requires immediate medical attention .

Taking iodine may rarely cause overactivity of the thyroid gland , underactivity of the thyroid Attachment 7.3, Guidance for Administering Potassium Iodide (Kl)

Title:

Emergency Exposure Levels / Protective Action Guides Page: 13 of 18 gland , or enlargement of the thyroid gland (goiter) . The only people who should not take potassium iodide are people who know they are allergic to iodine. One may take potassium iodide even if you are taking medicine for a thyroid problem (for example, a thyroid hormone or anti-thyroid drug) . Pregnant and nursing women can also take this drug.

D. Precautions

1. Potassium iodide should not be used by people allergic to iodine. In case of overdose or allergic reaction, refer the individual to medical personnel.

2. Doses recommended by these guidelines should be followed by all applicable personnel to avoid overdoses or insufficient protection.

3. Only the TSC Manager and EOF Manager (or the Shift Manager acting as Emergency Director) can authorize the use of a thyroid blocking agent (Kl) . The TSC Manager and EOF Manager (or the Shift Manager acting as Emergency Director) SHALL establish the extent and duration of the thyroid blocking agent (Kl) usage, based on radiological conditions and the advice of the Radiation Protection Manager or Radiological Emergency Manager, as appropriate.

E. Determination of Kl Use

• NOTE: If airborne Iodine concentrations have not been analyzed , consider plant conditions including the potential for unmonitored/unfiltered releases from the reactor coolant pressure boundary to occupied , or potentially occupied spaces.

In the event of a release involving radioiodine, the TSC Manager, in consultation with the Radiation Protection Manager, will issue instructions concerning the use of potassium iodide by in-plant emergency workers. The EOF Manager, in consultation with the Radiological Emergency Manager, will issue instructions to Energy Northwest environmental field teams and emergency workers in the Exclusion Area concerning the use of potassium iodide. The Emergency Director will notify offsite agencies (State, Counties, and DOE-RL) that the State of Washington's criteria for administration of Kl to Washington field teams has been met.

CAUTION The following criteria for recommending Kl for emergency workers applies to Washington State emergency workers only and not to Energy Northwest personnel.

The Energy Northwest criterion for dose is significantly higher and is presented later in steps E.2 and E.4 of this Attachment.

1. The EOF Manager, in consultation with the Radiological Emergency Manager, should notify the offsite agencies (State, Counties, and DOE-RL) authorities that the Washington State criteria for administering Kl based on the following criteria have been met:

• Air sample results > 1.4 x 10-7 µCi/cc 1-131 at 1.2 miles, OR

• Unfiltered or unmonitored release from a nuclear power plant

2. The TSC Manager, or the Shift Manager acting as the Emergency Director, in consultation with the Radiation Protection Manager, should recommend that emergency workers in any affected Protected Area location take Kl :

If the projected thyroid COE is 25 rem or more based on local air sampling and / or plant conditions . (See note.) 25 rem COE is 1000 DAC hours and is equivalent to an intake of approximately 25 microCuries of lodine-131.

NOTE: If airborne Iodine concentrations have not been analyzed , consider plant conditions including the potential for unmonitored I unfiltered releases from the reactor coolant boundary to occupied or potentially occupied spaces.

3. As directed by the Radiation Protection Manager, personnel within the Protected Area shall use appropriate respiratory protection , and/or Kl for thyroid protection.

CAUTION

• The following criteria for recommending Kl for emergency workers applies to Energy Northwest emergency workers only and not to Washington State personnel. The Washington State criteria for dose is significantly less and is presented in step E.1 of this Attachment.

4. The EOF Manager, in consultation with the Radiological Emergency Manager, should recommend that Energy Northwest emergency workers at affected locations outside the Protected Area (Security personnel , environmental field teams, etc.) take Kl:

• If the projected thyroid COE is 25 rem or more at 1.2 miles

• 25 rem COE thyroid is 1000 DAG-hours and is equivalent to an intake of approximately 25 µCi lodine-131

5. Determine the radiological conditions in occupied areas using the following methods, as applicable:

• Dose rate surveys

• Air samples

• Continuous Air Monitor (CAM) readings

• Area Radiation Monitor readings Attachment 7.3, Guidance for Administering Potassium Iodide (Kl)

• Plant effluent process monitor readings

• Offsite dose projection data

6. Determine if nonessential personnel could be evacuated from affected areas to prevent potential, large thyroid doses

7. Based on actual (or potential) radiological conditions , determine the projected thyroid dose to personnel in occupied , affected areas.

NOTE: The FDA's Bureau of Radiological Health and Drugs Bulletin Volume XVI ,

Number 7, recommends issuance of Kl to individuals projected to receive a thyroid dose of 25 rem COE or more.

8. If the projected dose to affected personnel has been exceeded, or is projected to exceed 25 rem COE thyroid , the RPM should recommend to the TSC Manager or the REM should recommend to the EOF Manager that Kl be administered (to affected personnel only).

NOTE: To be most effective, potassium iodide must be taken immediately prior to, or within a few hours after exposure to high concentrations of radioiodine.

9. If the TSC Manager or EOF Manager (or Shift Manager as Emergency Director) is advised to recommend administration of Kl to affected personnel, refer to Section F of this Attachment.

10. The EOF Manager should notify offsite authorities (State, Counties, and DOE-RL) when the State criteria for recommending Kl has been met.

NOTE: The use of potassium iodide is strictly voluntary.

F. Kl Issuance Instructions CAUTION Prior to issuing Potassium Iodide, personnel should be cautioned to NOT participate if they know that they are allergic to iodine.

1. Issue Kl to affected individuals as follows:

• Question personnel to determine if they know if they are allergic to iodine, and if so , DO NOT issue Kl to those individuals .

• Determine if individuals will voluntarily participate (by taking Kl) as directed.

• For participating individuals, issue one package of potassium iodide (Kl) tablets to each individual whose thyroid dose is projected to exceed 25 rem COE.

• Provide a thyroid blocking agent (Kl) information pamphlet to all individuals issued Kl and ensure personnel are aware of the following information :

The recommended Kl dosage is 130 mg daily (one 130mg or two 65mg tablets), for a period not to exceed 10 days Do not exceed the recommended dosage Begin taking Kl when advised to do so by the TSC Manager or Emergency Director.

To be most effective, Kl should be taken shortly before, or immediately after, exposure to radioiodine, however, the initial administration will still have substantial benefit if it is taken three or four hours after exposure If side effects are experienced, stop taking Kl, notify your supervisor and obtain medical attention

• Using the Personnel Accountability Log or other appropriate log, record the following information:

The name of the individuals contacted Whether the individual participated in Kl administration The date and time the individual began using Kl

2. Upon completion of Kl issuance to affected personnel, the RPM should inform the TSC Manager and the REM should inform the EOF Manager of any individuals that decline to use Kl .

3. Return all completed Personnel Accountability Logs or other logs used to issue Kl to the RPM and REM .

4. When directed, personnel should discontinue taking Kl and return the unused portion to the Plant for proper disposal.

I Use Category: REFERENCE Number: 13.2.2 Major Rev: 020 Minor Rev: 001 Title : Determining Protective Action Recommendations Page: 4 of 17 1.0 PURPOSE The purpose of this procedure is to provide instructions and guidance for the formulation of offsite Protective Action Recommendations (PARs) based on plant or radiological conditions and determining onsite protective action decisions. {R-1595}, {R-1596}

2.0 DISCUSSION 2.1 The responsibility for making PARs resides with the individual who has the responsibility of the Emergency Director. If the ERO is manned , The Emergency Director (ED) should obtain input from the Radiological Emergency Manager (REM) in the EOF for offsite PARs, and from the Radiation Protection Manager (RPM) in the TSC for recommendations for onsite protective actions, if possible .

2.2 PARs are based on plant or radiological conditions.

Recommendations for sections impacted are based on the following ;

• Plant Conditions - use attachment 7.1 note 6 "Downwind Section" table to define/select the downwind section(s) impacted.

• Radiological Conditions - use dose projection program to define/select the downwind section(s) impacted .

• 2.2.1 2.2.2 Evacuation - A type of protective action in which instructions are given to evacuation and control of access to an affected area can be the most effective protective action for reducing the dose to the public. However, constraints such as severe weather conditions, obstruction of roads and limited time may impact the benefits of evacuation.

Shelter In Place (SIP) - A type of protective action in which instructions are given to members of the public to remain indoors, turn off heating or air conditioning (as appropriate for the region and season) , close windows, monitor communication channels, and prepare to evacuate. Shelter in Place should be given to those sections where impediments to Evacuation exist or if a controlled release due to controlled venting of the primary containment is being performed.

2.2.3 Monitor and Prepare- A type of precautionary action intended to advise the public within the EPZ that a serious emergency at the nuclear power plant exits and that it should monitor the situation and prepare for the possibility of Evacuation, Shelter in Place, or other protective actions. Monitor and Prepare should be given to the 2 to 1O miles sections that are not affected by the downwind plume .

I Use Category: REFERENCE Number: 13.2.2 Major Rev: 020 Minor Rev: 001

Title:

Determining Protective Action Recommendations Page: 5 of 17 2.3 Additional EPZ sections should not be recommended for evacuation unless conditions make it necessary to do so. Expanding the evacuation zone when conditions do not require this action could present a greater hazard to evacuees than allowing them to remain in place. Needless evacuation also reduces the effectiveness of the offsite resources used to accommodate the evacuation.

2.4 Changes in wind direction may indicate that if a release beg ins, it would affect different downwind section(s) . If there are indications that containment may fail , a new PAR for new section(s) should be issued . If a radiological assessment shows that an ongoing release or ongoing containment source term is not sufficient to cause exposures in excess of EPA protective action guidelines, the PAR should not be expanded based only on changes in wind direction.

2.5 Industrial Development Complex personnel are evacuated at the Site Area Emergency classification per PPM 13.5.1.

2.6 There are precautionary offsite protective actions that are recommended automatically at the Site Area Emergency and General Emergency classifications. These are specified under the Site Area Emergency and General Emergency boxes on the Classification Notification Form (CNF) (Form 24075) . If there are PARs in addition to those that are automatic, they are addressed for the General Emergency in box# 6. Implementation of protective actions for offsite areas within the 10 mile EPZ is the responsibility of Benton and Franklin Counties and DOE-RL officials.

2.7 The protective actions outlined in this procedure are limited to actions for minimizing the exposure of the public within the 1O mile EPZ to external and internal radiation exposure from plume passage or inhalation of the radioactive plume and actions to determine PARs beyond the 10 mile EPZ. Other protective actions for minimizing public exposure via the ingestion pathway will be determined and implemented by Energy Northwest and Washington State.

2.8 Plant and offsite officials should continue assessment actions based on additional plant information, dose projections, and field monitoring results. After performing the initial early evacuation actions near the plant, licensee and offsite officials should modify their protective action recommendations as necessary based on field monitoring and dose projections, which indicate that EPA protective action guide doses may be exceeded in areas beyond those that have been evacuated. On the basis of this information , plant and offsite officials may expand the evacuations to encompass other areas in the plume EPZ and , for the worst case accidents ; protective actions may be required beyond the plume EPZ.

2.9 Once a PAR is made for evacuation of a 1O mile EPZ section and action has been taken by an agency to implement that recommendation as a Protective Action Decision (PAD) , do not replace the evacuation PAR with a sheltering PAR. {5.1.2}

This path is used for scenarios in which containment integrity can be determined as bypassed or immediately lost during a GE with core damage.

If this scenario cannot be immediately confirmed, assume it is not taking place and answer "no" to this decision block.

A rapidly progressing severe incident may be defined as:

1. The PAR is the first after a GE has been declared .

AND

2. There is loss of the containment barrier per the Emergency Action Levels AND

3. EITHER of the following :

a. Containment Radiation Monitor CMS-R1S-27E and CMS-R1S-27F reading GT 14,000 R/Hr.

OR

b. A significant radiological release (greater than PAGs at 1.2 miles) in about an hour.

Note 2: Known lmpediment(s) to Evacuation or Controlled Release

• If the General Emergency is due to Hostile Action, then this would be considered an Impediment to Evacuation . This impediment is effective until the Off-Site Incident Commander has determined that conditions are safe for evacuations to proceed and communicated this to CGS Emergency Director.

• If notified by OROs prior to beginning the PAR determination that; adverse weather, earthquake, wildfire, etc ... would preclude the safe or timely evacuation of the public at the time of the emergency, then that condition constitutes a known Impediment to Evacuation .

• Controlled Release , Primary Containment venting that is performed to prevent containment failure and can be terminated within one hour. Controlled means that the release was initiated by Operator Action and can be terminated by Operator Action .

Note 3: Evacuate; Evacuation and control of access to an affected area can be the most effective protective action for reducing the dose to the public unless circumstances as discussed in note 2 exist.

Title:

Determ ining Protective Action Recommendations Page: 16 of 17 Note 4: Shelter In Place (SIP) ; Shelter in Place should be given to those sections where impediments to evacuation exist or if a controlled release due to controlled venting of the primary containment is being performed . Given that a decision could be made to Shelter in Place for a short duration release (containment venting) , it should be recognized that Shelter in Place is a temporary measure and does not provide long-term protection from airborne radioactive materials. It loses effectiveness as interior air equalizes in concentration with the outside environment. Therefore , any recommendation for the public to Shelter in Place should be followed by additional instructions at the appropriate time.

Note 5: Monitor and Prepare ; The instruction to monitor and prepare is intended to engage the population within the plume exposure pathway emergency planning zone, inform them of the emergency, and advise them that they should monitor the situation and prepare for the possibility of Evacuation, Shelter in Place, or other protective actions. Monitor and Prepare should be given to the 2 to 10 miles sections that are not are not affected by the downwind plume.

Note 6: Downwind Section(s)

Sections for the surrounding 10-mile EPZ are divided into 4 - 90° sections.

Determining which section(s) that are impacted may be performed by:

• Using dose projections software, or

• Using the following table .

Downwind Sections Wind Direction Sections (from) Impacted 012° to 079° 3 080° to 124° 3, 4 125° to 146° 4 147° to 214° 1, 4 215° to 259° 1 260° to 304° 1, 2 305° to 326° 2 327° to 011 ° 2, 3 Note 7: Continue Assessments Radiological and meteorolog ical assessments should be continued and evacuation considered for any areas where dose projections or field measurements indicate that PAGs may be exceeded.

Note 8: Are lmpediment(s) to Evacuation Removed? And Controlled Release Stopped?

Both actions must be yes if either condition had occurred earlier (note 2) or the condition is not applicable.

OR 50 - 500 Rem skin Sheltering may be the preferred protective action when it will provide protection equal to or greater than evacuation , based on consideration of factors such as source term characteristics, and temporal or other site-specific conditions .

Evacuation vs. Sheltering Because of the higher risk associated with evacuation of some special groups in the population (e.g.

those who are not readily mobile) , sheltering may be the preferred alternative for such groups as a protective action at projected doses up to 5 Rem TEDE. In addition, under unusually hazardous environmental conditions, use of sheltering at projected doses up to 5 Rem to the general population (and up to 10 Rem to special groups) may be justified .

While Offsite Officials will determine when the use of Sheltering is appropriate, the CGS Emergency Director will consider these principles when deciding to recommend to Evacuate or Shelter in accordance with this procedure.

Title:

TSC Ventilation Radiation Monitor System Operations Page: 4 of 12 1.0 PURPOSE This procedure provides instructions for operating the Technical Support Center (TSC)

Ventilation System Radiation Monitoring System TSC-CP-RAD/1.

2.0 DISCUSSION The TSC Ventilation System Radiation Monitoring System continuously monitors and provides alarms for elevated airborne contamination levels in the TSC during an emergency.

TSC-RIS-1A is the TSC Airborne Particulate Radiation Monitor, TSC-RIS-1B is the TSC Airborne Radiation Monitor for Iodine and TSC-RIS-1C is the TSC Airborne Radiation Monitor for Noble gas.

Chemistry Calculation CH-98-002 provides the Setpoint information for these monitors. The setpoint value is selected to allow operating margin between the calculated limit and actual setpoint. The value in the calculation is based the requirement for posting areas above 0.3 DAC as an airborne radiation area. This will provide a High and Hi-Hi alarm set points equivalent to 0.3 DAC and 1.0 DAC, respectively, for a condition which affects TSC habitability.

3.0 RESPONSIBILITIES The OSC Health Physics Technician assigned to perform TSC Habitability functions is responsible for performing tasks controlled by this procedure.

4.0 PRECAUTIONS AND LIMITATIONS 4.1 TSC-CP-RAD/1 audible alarm is loud. Hearing PPE should be worn while working at this panel.

4.2 During Start-up and Operation of the TSC-CP-RAD/1 unit, the "FAIL" alarm may actuate (e.g.,

low flow, low counts, high voltage etc.).

4.3 The photomultiplier tubes are light sensitive and can easily be damaged from normal light intensities with high voltage to the detector. Do not remove the shield plug/filter housings potentially exposing the detector assemblies to light.

4.4 Air Handling Unit fan motors can start and stop at any time. Be aware of rotating equipment located behind equipment guards and shrouds.

4.5 During initial start-up phase, the RIS LOW COUNTS indicating lamps may illuminate for up to 30 minutes due to low down scale indication .
