Dear Mr. Keppler:
Commonwealth Edison and many others working for the States of
~
Illinois, Iowa and Wisconsin, the NRC Region III and FEMA Region V, have been trying to develop a convenient reference table of protective actions for nuclear station eme e ncies. The latest draft of this table is enclosed.
This version of the criterin is very similar to that used at the July 29th, Commonwealth Edison Zion exercise. The only differences are: (1) the inclusion of a new section (4) in the dose projection mlumn of General Emergency to cover the " low dose" situations, and (2) an expanded footnote (the one noted with an asterisk) to explain the evacuation policy in Iowa and Wisconsin.
This table still contains the " imminent" class of NARS form section 6 used in Illinois and does not address Iowa's use of the upper rather than t. e lower PAG's used by Illinois and Wisconsin. These two issues are yet unresolved.*
In the meanwhile, these criteria will be used at the Dresden September 30th exercise by Cor.monwealth Edison and will probably be incorporated into the next revision of our emergency plan. As currently drafted this table meets the criteria of NUREG 0654.
If you have any comments on these criteria I welcome them.
Sincerely yours, p
/
