Personnel Error This classification is assigned to occurrences attributed to human errors.

When errors are made as a result of following incorrect written procedures, the occurrence should.be entered under defective procedures (see Paragraph D below).

When er'rors are made because written procedures are not followed or because qualified personnel do not perform in accordance with accepted or approved practice, the occurrence should be classified under personnel error.

NOTE:

For occurrences attributed to this classification, the specific type of personnel involved (licensed and senior operators, non-licensed operations personnel, etc.)

must be designated under Item 13 of the LER form.

D'esi n, Manufacturin, Construction/Installation - This classifi-cation is assigned to occurrences reasonably attributed to design, manufacture, construction or installation of the system, component or structure resulting in the event.

For example, failures that are traced to such things as defective materials, significant breakdown in the quality assurance program or components otherwise unable to meet the specified functional requirements or performance specifications should be included in this classification.

NOTE:

For occurrences attributed to this classification, the specific assignable proximate

cause

(design, manufacturing, construc-tion/installation) must be designated under Item 13 on the LER form.

External Cause - This classification is assigned to occurrences attributed to natural phenomena.

A typical example includes an event such as loss of offsite power resulting from a lightning strike, tornado or flood.

Defective Procedures This classification is assigned to occurrences caused by inadequate or incomplete written procedures (see Paragraph A above) or instructions.

Com onent Failure This classification is assigned to occurrences or events attributed to component malfunctions resulting in failure of the equipment to perform its intended function.

The performance of equipment outside limits specified in the Technical Specifications, the Safety Analysis Report or other applicable requirements, should be included here unless the proximate cause clearly should 'be otherwise assigned.

This classification should be used whenever the cause of equipment failure cannot reasonably be attributed to

design, manufacturing, construction or installation errors (see Paragraph B above).

Considerable judgment is required to segregate equipment failures caused by operating or maintenance errors or deficiencies (see Paragraph A above).

NOTES:

1.

This classification is to be used

~oui when a component failure caused the event, with the details provided under cause descrip-tion. If one or more components fail because of some event, choose the appropriate proximate

cause

code and provide details of the component failures under the event description.

2.

For occurrences attributed to certain component failures, the specific component must be further categorized under Item 13.,

Other This.classification shall be assigned to occurrences for which the proximate

cause

cannot be identified or which cannot be assigned to one of the classif ications noted above.

Personnel Error>> This classification is assigned to occurrences attributed to human errors.

When errors are made as a result of following incorrect written procedures, the occurrence should be entered under defective procedures (see Paragraph D below).

When er'rors are made because written procedures are not followed or because qualified personnel do not perform in accordance with accepted or approved practice, the occurrence should be classified under personnel error.

NOTE:

For occurrences attributed to this classification, the specific type of personnel involved (licensed and senior operators, non-licensed operations personnel, etc.)

must be designated under Item 13 of the LER form.

'esi n, Hanufacturin, Construction/Installation - This classifi-cation is assigned to occurrences reasonably attributed to design, manufacture, construction or installation of the system, component or structure resulting in the event.

For example, failures that are traced to such things as defective materials, significant breakdown in the quality assurance program or components otherwise unable to meet the specified functional requirements or performance specifications should be included in this classification.

NOTE:

For occurzences attributed to this classification, the specific assignable proximate

cause

(design, manufacturing, construc-tion/installation) must be designated under Item 13 on the LER form.

External Cause - This classification is assigned to occu'rrences attributed to natural phenomena.

A typical example includes an event such as loss of offsite power resulting from a lightning strike, tornado or flood.

Defective Procedures - This classification is assigned to occurrences caused by inadequate or incomplete written procedures (see Paragraph A above) or instructions.

Com onent Failure - This classification is assigned to occurrences or events attributed to component malfunctions resulting in failure of "the equipment to 'perfo'rm its intended function.

The.perfotmance of equipment outside limits specified in the Technical Specifications, the Safety Analysis Report oz other applicable requirements, should be included here unless the proximate cause clearly should be otherwise assigned.

This classification should be used whenever the cause of equipment failure cannot reasonably be attributed to

design, manufacturing, construction or installation errors (see Paragraph 3 above).

Considerable judgment is required to segregate equipment failures caused by operating or maintenance errors or deficiencies (see Paragraph A above).

NOTES:

1.

This classification is to be used

~onl when a component failure caused the event, itvh the details provided under

cause

descrip tion.

Zf one or more components Eaii because of some event, choose the appropriate proximate cause code and provide details of the component failures under the event description.

2.

For occurrences attributed to certain component failures, the specific component must be further categorized under Item 13.

Other.

This classification shall be assigned to occurrences for which the proximate

cause

cannot be identified or which cannot be assigned to one of the classifications noted above.
