Title:
Determining Protective Action Recommendations Page: 4 of 16 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. Ifthe 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 5 "Downwind Section" table to definelselect the downwind section(s) impacted.
- Radiological Conditions - use dose projection program to define/select the downwind section(s) impacted.
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 begins, 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 # 6a. Implementation of protective actions for
- ---*'offsite
- areas within the 10 mile EPZ is the responsibility of Benton and Franklin Counties and DOE-RL officials.

Title:
Determining Protective Action Recommendations Page: 5 of 16
- - 2.7 The protective actions outlined in this procedure are limited to actions for minimizing the exposureof the public within the 10 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 10 mile EPZ section and action has been taken by an agency to implement that recommnendation as a Protective Action Decision (PAD), do not replace the evacuation PAR with a sheltering PAR. (5.1 .2}
3.0 RESPONSIBILITIES 3.1 The Emercqency Director is responsible for:
3.1.1 Determining and making offsite Protective Action Recommendations (PARs);
3.1.2 Ensuring PARs are transmitted to the appropriate Offsite Authorities.
3.2 The Radiation Protection Mana~qer (RPM) is responsible for:
3.2.1 Assess offsite doses and make recommendations concerning protective actions to the TSC Manager until the Radiological Emergency Manager at the EOF takes over this function.
3.3 The Radiological Emergqency Managqer (REM) is responsible for:
3.3.1 Managing radiological dose assessment and field monitoring activities.
3.3.2 Assists in development of PARs and, during the late phases of the response, coordinates this activity with the States of Washington and Oregon and the US DOE and provides offsite radiological PARs to the EOF Manager.

Title:
Determining Protective Action Recommendations Page: 14 of 16 Note 1: Rapidly Progressing Severe Accident A rapidly progressing severe incident is a General Emergency (GE) with rapid loss of containment integrity (emergency action levels indicate containment barrier loss) and loss of
~ability to cool the core. 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:
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-RIS-27E and CMS-RIS-27F reading GT 14,000 RIHr.
- b. A significant radiological release (greater than PAGs at 1.2 miles) in about an hour.
Note 2: Known Impediment(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:
Determining Protective Action Recommendations Page: 15 of 16 Note 4: SHELTER (Shelter in Place)
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 season), close windows,
-- monitor communications channels, and prepare to evacuate.
... -.. Sheltering in buildings with windows and doors closed and ventilation turned off can provide partial protection from a passing radioactive plume. The extent of the protection depends on the duration and isotopic mixture of the release and the type of building.
Given that a decision could be made to Shelter for a short duration release (containment venting), it should be recognized that Shelter 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 should be followed by additional instructions at the appropriate time.
See also note 6.
Note 5: Downwind Section(s)
Sections for the surrounding 10-mile EPZ are divided into 4 - 900 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 0120 to 0790 3 080° to 1240 3, 4 125° to 1460 4 147° to 214° 1, 4 215° to 259° 1 260° to 304° 1, 2 35 05 to 3260 2 327° to 011 ° 2, 3 Note 6: Continue Assessments Radiological and meteorological assessments should be continued and evacuation considered for any areas where dose projections or field measurements indicate that PAGs may be exceeded.
Note 7: Are Impediment(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:
Determining Protective Action Recommendations Page: 4 of 16 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. Ifthe 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 5 "Downwind Section" table to definelselect the downwind section(s) impacted.
- Radiological Conditions - use dose projection program to define/select the downwind section(s) impacted.
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 begins, 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 # 6a. Implementation of protective actions for
- ---*'offsite
- areas within the 10 mile EPZ is the responsibility of Benton and Franklin Counties and DOE-RL officials.

Title:
Determining Protective Action Recommendations Page: 5 of 16
- - 2.7 The protective actions outlined in this procedure are limited to actions for minimizing the exposureof the public within the 10 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 10 mile EPZ section and action has been taken by an agency to implement that recommnendation as a Protective Action Decision (PAD), do not replace the evacuation PAR with a sheltering PAR. (5.1 .2}
3.0 RESPONSIBILITIES 3.1 The Emercqency Director is responsible for:
3.1.1 Determining and making offsite Protective Action Recommendations (PARs);
3.1.2 Ensuring PARs are transmitted to the appropriate Offsite Authorities.
3.2 The Radiation Protection Mana~qer (RPM) is responsible for:
3.2.1 Assess offsite doses and make recommendations concerning protective actions to the TSC Manager until the Radiological Emergency Manager at the EOF takes over this function.
3.3 The Radiological Emergqency Managqer (REM) is responsible for:
3.3.1 Managing radiological dose assessment and field monitoring activities.
3.3.2 Assists in development of PARs and, during the late phases of the response, coordinates this activity with the States of Washington and Oregon and the US DOE and provides offsite radiological PARs to the EOF Manager.

Title:
Determining Protective Action Recommendations Page: 14 of 16 Note 1: Rapidly Progressing Severe Accident A rapidly progressing severe incident is a General Emergency (GE) with rapid loss of containment integrity (emergency action levels indicate containment barrier loss) and loss of
~ability to cool the core. 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:
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-RIS-27E and CMS-RIS-27F reading GT 14,000 RIHr.
- b. A significant radiological release (greater than PAGs at 1.2 miles) in about an hour.
Note 2: Known Impediment(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:
Determining Protective Action Recommendations Page: 15 of 16 Note 4: SHELTER (Shelter in Place)
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 season), close windows,
-- monitor communications channels, and prepare to evacuate.
... -.. Sheltering in buildings with windows and doors closed and ventilation turned off can provide partial protection from a passing radioactive plume. The extent of the protection depends on the duration and isotopic mixture of the release and the type of building.
Given that a decision could be made to Shelter for a short duration release (containment venting), it should be recognized that Shelter 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 should be followed by additional instructions at the appropriate time.
See also note 6.
Note 5: Downwind Section(s)
Sections for the surrounding 10-mile EPZ are divided into 4 - 900 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 0120 to 0790 3 080° to 1240 3, 4 125° to 1460 4 147° to 214° 1, 4 215° to 259° 1 260° to 304° 1, 2 35 05 to 3260 2 327° to 011 ° 2, 3 Note 6: Continue Assessments Radiological and meteorological assessments should be continued and evacuation considered for any areas where dose projections or field measurements indicate that PAGs may be exceeded.
Note 7: Are Impediment(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.
