1. 4ALYSIS OF OCCURPaiG:

The safety significance connected with this occurrence is that any unusually large release of particulate activity during this period night not have been recognized until the conthly corpo-site analyses were complete. This i.s not a likely possibility as a spectne analysis was perforced to neasure releases of short-lived isotopes and if unusually large amounts of activity In addition,

-woro present, it would have been readily apparent.

a spectrum analysis of the charcoal filter had also been per-forned and norcal quantitics of Iodine were found.

COPECTIVE ,

ACTION: " = particulate filter was counted nine days after filter re-

~ upon discovery of the abnormal occurrence. The gross a, j

gro, p, and gross y values were companble to stcples recoved before and after this filter. lhis would indicate that there l

l was little or no change in plant gasecus effluents and that the l

plant was operating with releases less than 4% of the Technic .
