Procedure No El-6.13 Revision 11 Effective Date 12118/03 PALISADES NUCLEAR PLANT EMERGENCY IMPLEMENTING PROCEDURE TITLE: PROTECTIVE ACTION RECOMMENDATIONS FOR OFFSITE POPULATIONS Approved: NKBrott l

12116/03 Procedure Sponsor Date I'j New Procedure/Revision Summary:

Revision 11 Specific Changes This revision was initiated to clarify when the Minimum Protective Action Recommendation should be used. In addition, the evacuation time estimates in Attachment 4 were updated to include the new time estimates from the November 2003 Evacuation Time Estimate Study for Palisades.

Specifics:

6.3.1 A note was added to remind users not to automatically stop In the minimum recommendation box but to consider the core/containment and dose status boxes as well.

The wording MINIMUM INITIAL was eliminated to clarify for users the other boxes should be considered as well for initial recommendations.

6.3.1 a & b The word minimum was eliminated to remove the tendency of users to stop in the minimum box for initial recommendations.

6.3.2 b This section was added to include the guidance of Regulatory Issue Summary 2003-12. This gives the users additional instruction on changing protective action recommendations for an area which has already had a protective action ordered by the State of Michigan. was revised to make the flowchart clearer on the use of the minimum protective action box. The intent is to lead the user to consider all three protective action boxes for initial recommendations and not stop in the minimum box.

Additional changes to the wording in the protective action recommendations on the flowchart were made to include the use of the areas instead of only uradiusu. These changes were requested by the Operations Department as a result of procedure usage in license operator requalification training. Evacuation Time Estimates were updated based on the new evacuation time estimate study.

1.0 RESPONSIBILITIES AND AUTHORITIES This procedure provides protective action recommendations. The authority and responsibility for the selection and implementation of offsite response options rests fully with the appropriate state and local authorities. Nuclear Management Company (NMC) has no authority with respect to imposing protective response options beyond the boundaries of its site.

1.1 If the Technical Support Center (TSC) is not operational, the Shift Manager/Site Emergency Director is responsible for recommending protective actions to local or state authorities.

1.2 If the TSC is operational, but the Emergency Operations Facility (EOF) is not operational, Radiation Protection staff will be responsible for providing dose calculations and advising the Site Emergency Director on protective action recommendations. The Operations Support Group is responsible for providing core damage determinations. The Site Emergency Director is responsible for recommending protective actions to the local or state authorities.

1.3 If the EOF is operational, the Radiation Protection staff in that facility is responsible for providing dose calculations and advising the EOF Director on a protective action recommendation. A Reactor Engineer is available to provide core damage determinations. The EOF Director is responsible for making protective action recommendations and should discuss the protective action with the SED before recommending protective actions to the local or state authority.

2.0 PURPOSE This procedure provides guidelines for determining protective actions for the general public to be recommended to the appropriate local or state authorities in the event of a radiological emergency.

PALISADES NUCLEAR PLANT Proc No El-6.13 EMERGENCY IMPLEMENTING PROCEDURE Revision 11 Page 3 of 7 TITLE: PROTECTIVE ACTION RECOMMENDATIONS FOR OFFSITE POPULATIONS 4.0 INITIAL CONDITIONS AND/OR REQUIREMENTS 4.1 provides a flowchart of PARs and the recommended protective actions for the plume exposure pathway. The flowchart is divided into four sections:

EMERGENCY CLASSIFICATIONS - Protective actions that are required at the declaration of each emergency classification.

MINIMUM RECOMMENDATIONS - Minimum protective action recommendations when a General Emergency is being declared.

CORE/CONTAINMENT STATUS - Protective actions that are required whenever major core/containment failure has occurred, or is projected.

OFFSITE DOSE STATUS - Protective actions that are required when offsite doses exceed the EPA protective actions dose limits.

4.2 also includes tables for identifying affected areas.

s 4.3 is a map showing sectors and areas.

4.4 converts the direction the wind is coming from to the 3 affected downwind sectors.

4.5 provides evacuation time estimates for the 10 mile Emergency Planning Zone (EPZ).

PALISADES NUCLEAR PLANT Proc No El-6.13 EMERGENCY IMPLEMENTING PROCEDURE Revision 11 Page 4 of 7 TITLE: PROTECTIVE ACTION RECOMMENDATIONS FOR OFFSITE POPULATIONS 5.0 PRECAUTIONS AND LIMITATIONS This procedure is a guide for determining recommended protective actions. Since it is impossible to cover all potential situations, the judgment of the person responsible for recommending protective actions shall take precedence over the requirements of this procedure. However, since the protection of the general public is the ultimate concern, protective actions less stringent than those in this procedure should be recommended only if constraints make the actions a greater hazard to public health.

NOTE:

Severe core damage is indicated by:

1.

Loss of critical functions required for core protection (eg, loss of injection combined with a LOCA);

2.

High core temperatures;

3.

Very high radiation levels in area or process monitors.

Following the declaration of a General Emergency, the initial minimum protective action recommendation must focus on the status of the core. IF severe core damage cannot be ruled out, THEN the initial recommendation shall be to evacuate.

It may be concluded that severe core damage cannot be ruled out' if any of the following conditions exist:

a.

If there are symptoms of severe core damage, whether explainable or not.

b.

If there is not enough information to positively state that there is no severe core damage.

c.

If current plant conditions persist, severe core damage is projected, unless some improvement is seen in plant conditions.

Field surveys should be conducted to confirm dose projections. If these recommendations are available at the time a recommendation is made, they should be considered together with the dose projection. However, a protective action recommendation should not be delayed until field survey results are reported.

If Protective Action Guidelines are exceeded beyond 10 miles, consult with the state on ad hoc protective actions.

Where required, sign appropriate sign-off blanks to certify that all segments are complete.

6.1 DECLARATION OF UNUSUAL EVENT OR ALERT 6.1.1 Unusual Event - No protective actions required. Emergency Implementing Procedure El-3, "Communications and Notifications," Attachment 1, "Emergency Notifications Form,' should be used.

6.1.2 Alert - No protective actions required beyond accountability.

6.2 DECLARATION OF A SITE AREA EMERGENCY 6.2.1 Evacuate nonessential personnel from the site per Emergency Implementing Procedure El-13, Evacuation/Reassembly."

6.3 DECLARATION OF GENERAL EMERGENCY 6.3.1 Initial Recommendation I

NOTE:

The Initial recommendation that is formulated should evaluate whether the Minimum, Core/Containment, or Dose Status recommendation is applicable.

The declaration of a General Emergency requires that an INITIAL PROTECTIVE ACTION RECOMMENDATION be formulated (see Attachment 1, Pages 1 and 2) and communicated to offsite authorities.

a.

IF the State Emergency Operations Center is not activated, THEN the SED shall personally communicate the General Emergency and the initial protective action recommendation to Van Buren County.

I I

b.

WHEN the State Emergency Operations Center (EOC) is activated, THEN the General Emergency and the initial protective action recommendation shall be I

communicated directly (via telephone) from the SED/EOF Director to the State EOC Director.

PALISADES NUCLEAR PLANT Proc No El-6.13 EMERGENCY IMPLEMENTING PROCEDURE Revision 11 Page 6 of 7 TITLE: PROTECTIVE ACTION RECOMMENDATIONS FOR OFFSITE POPULATIONS 6.3.2 Follow-Up Recommendation

a.

Using available Plant status information, dose projections, and/or field surveys, and Attachment 1, 'Protective Action Recommendation Flowchart,'

evaluate and recommend a follow-up protective action. Notification to the appropriate state and local authorities shall be made as soon as the recommendation has been prepared (not later than 30 minutes after initial recommendations).

b.

Assess the conditions affecting the follow-up protective action and make revisions to the protective action recommendation that include appropriate consideration of the protective action orders given to the public by offsite authorities. For example: If a protective action order has been given to the public to evacuate an area, a change in protective action recommendation to shelter would not be appropriate until the source of the threat to the public is clearly under control.

c. provides a work sheet that may be used to assist in determining Projected TEDE, adult thyroid CDE, and/or skin DE from field survey data.

6.3.3 The Radiation Protection Group Leader should provide the protective action recommendation for SED/EOF Director approval.

6.3.4 Record the recommended protective action and affected area(s) on the Emergency Notification Form.
