Re: New Source Term

[LIPTONW@dteenergy.com]

The NRC published a "Federal Register" notice (Vol. 64, No. 47, March 11, 
1999, pages 12117 - 12126).  This proposed rulemaking refers to the source 
terms in NUREG-1465.  The notice states:  "Where TID-14844 [current source 
terms]  addressed three categories of radioniuclides, the revised source
terms 
categorize the accident release into eight groups on the basis of similarity 
in chemical behavior.  Where TID-14844 assumed an immediate release of the 
activity, the revised source terms have five release phases that are 
postulated to occur over several hours, with the onset of major core damage 
occurring after 30 minutes.  Where TID-14844 assumed radioiodine to be 
predominantly elemental, the revised source terms assume radioiodine to be 
predominantly cesium iodide (CsI), an aerosol that is more amenable to 
mitigation mechanisms..." 
 
The opinions expressed are strictly mine.   
It's not about dose, it's about trust.
