(2)

Reliable - event classification should be based

______________

upon dependable event indicators which are,

whenever possible, directly related to the

severity of the accident.

______________

(3)

Internally consistent - different events of a

similar severity should result in the same

classification and different indicators of the same

event should be recognizable as such and result

in the same classification.

(4)

Anticipatory - when deciding which classifica-

______________

tion level an EAL is assigned to, the response

level necessary to address the potential

consequences of the events in progress, rather

than just the severity of the event at the time it is

recognized, should be considered.

(5)

Redundant - repetition of EALs in procedures,

______________

checklists, control panels, etc. will increase the

probability that an event will be recognized and

the event classification process initiated

(6)

Complete - all events and associated observable

______________

indicators identified in the facility/site hazards

assessment should be incorporated in the event

classification system, including multiple contem-

poraneous events.

(7)

Conservative - conditions lacking detailed or

______________

quantitative indicators should be classified on

the assumption that the condition has either

challenged or failed the engineered barriers until

confirmed safe by more direct methods.
