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

Within these areas, the inspection consisted of selective

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

The personnel performing verification signatures, in these cases, were not the
personnel who had performed or observed the specified ac' tion. Our concern was

heightened, since the people involved were supervisory.
The testing areas examined appeared to be performed in a manner which provides '
!
generally adequate assurance of system operability.
Strengths were noted in

your testing programs, particularly, the strong involvement of your

engineering organization in establishing testing requirements.
