9.1.1 Select the overlay corresponding to the atmospheric sta-

{ bility when that segment was released. .

9.1.2 Using the total broken path distance to the segment start-ing point (as recorded on the centerline plot), mark the segment starting point on the centerline of the stability overlay.

9.1.3 Place the overlay under the tracing paper bearing the cen-terline plot, aligning the segment starting points and centerlines.

l 9.1.4 Trace the bounding X/Q lines for the segment, connecting

} smoothly with the adjacent segment. (It is usually helpful i

i to extend the botndary lines en inch or so beyond the seg-ment endpoint).

I 9.2 Darken the plume outline.

9.3 Affix the tracing sheet to a 10-mile radius emergency planning map, aligning the north-south directions, and centering the starting point

) of the youngest plume segment over the plant site.

10.0 DOSE COMMITMENT INTEGRATICN 1

10.1 At the top, leftmost open column on Form 1904.06B, list the starting and ending times for the earliest segment not previously listed. Sub-tract the starting time from the ending tiae to determine the dura-tion of this integration period in hours. A separate set of forms must be maintained for whole body and for child thyroid doses.

10.2 Using the data tabulated on Form 1904.06A, record the child thyroid and whole body dose rates associated with the plume segment currently crossing the radii listed on Pages 1-5 of 1904.06B. Record the cen-terlme dose rate on the line for the sector where the intersectbn CCcurs.

DATE Owam 10.3 Multiply the dose rates obtained in Step 10.2 times the duration to determine the incremental whole body and child thyroid integrated doses. Record these in the 'A' Dose column on the whole body and child thyroid worksheets (Form 1904.06B), on the appropriate sector /

radius line.

NOTE: When the plume centerline falls between two sectors, add the incremental deses to both sectors.

10.4 For each sector / radius line on Form 1904.06B, add the entry in the current 'A' Dose column to the entry in the previous 'I' Dose column and record the new total integrated dose in the current 'I' Dose column. This will result in a running total being generated from left to right across the page.  ;

NOTE: The integrated doses at all offsite location's are assumed to be zero prior to an incident; therefore, the first 'I' Dose column of an incident will equal the first 'A' Dose column.

10.5 Circle the hignest integrated exposure value for each major radius (0.65,1.0, 2.0, 5.0, and 10.0 miles) and for both dose types (whole body and child thyroid).

,) 11.0 PROTECTIVE ACTION RECOMMENDATICNS 11.1 Recommend protective action in affected offsite subsectors when trends indicate that:

11.1.1 Whole body integrated dose may approach 1 R (1000 mR), or j

11.1.2 Child thyroid integrated dose may approach 5 R (5000 mR).

11.2 Recommend protective action in affected onsite (exclusion area) sub-sectors when trends indicate that:

11.2.1 Whole body integrated dose may approach 0.5 R (500 mR), or 11.2.2 Child thyroid integrated Cese may approach 1.0 R (1000 mR).
