SUBJECT: NRC Systematic Test Performance Team Inspection '

Inspection Report Nos. 50-361/93-27 and 50-362/93-27

This refers to a-special test team inspection conducted'at the San Onofre

Nuclear Generating Station, Units 2 and 3, by Mr. P. P. Narbut and a team of ,

'

.

NRC and contractor personnel, .from September 20 through October 22, 1993. At ~

the conclusion of the inspection, the findings were discussed with those (

members of your staff identified in the enclosed report.

Areas examined during this inspection were post-maintenance testing, post-

modification testing, technical specification surveillance testing, ASME- ,

inservice testing, predictive maintenance testing and testing associated with

Generic Letter 89-13, " Service Water System Problems Affecting Safety-Related

Equipment." Within these areas, the inspection consisted of selective

examinations of procedures and records, interviews with personnel, and 3

observations of activities by the inspectors.

Bas ~ed on the results of this inspection, certain of your activities appeared

to be in violation of NRC requirements, as specified in the enclosed Notice of l

Violation (Notice). These violations, taken in aggregate, create a concern  :

for the possibility that complacency, or less than quality performance, is j

being accepted from some craft and first or second line supervisors.

The violations involved a failure to follow a procedure requirement to

personally verify any work signed for, failure to follow procedure (five -

examples), inappropriate acceptance criteria in procedures (two examples),

procedures that were not appropriate to the circumstances, failure to do a 10

CFR 50.59 safety evaluation, and failure to implement piping code

requirements. Of particular note were two violations that dealt with ,

personnel signing for work that they did not personally perform, and with a ,

f ailure to follow procedure for verifying a gap clearance, that led to damage

of a salt water cooling pump.

The inspection found that the procedure steps which were violated were

appropriate and if followed would have prevented the damage to the pump which

occurred. The inspection determined that, although the maintenance department '

generally had well written and detailed maintenance procedures, maintenance

personnel did not always follow the instructions specified in these procedures

or change the procedure when appropriate. The cases involving the failure to
