has resu1 ed 1 a une pectedly large nu ber of emergency declara io s by licensees and the concotr¢i& t large number of needless activations of local sta e, and federa emergen~y plans. For example during Janu ary 1983, there were 163 telephone notifications to the RC Operatio s Center pursuan to 10 CFR

indica ive of more serious condi io s which are no yet fully realized." In other ords, he U usual E ent no ifica ions are useful o e Co ission as onemergency reports but no as precursor notif'cat*ons of se ious a~cide s.

The Co,, *ssio tins a it would e int e interes of pu ic eal, and safety to remove the Unusual Event class fro t e emergency classes lea ing only three uc classes: Alert, Site Area Emergenc~and General Err~rgency.
