SUBJECT: NRC INSPECTION REPORT 50-331/98-04; 50-362/98-04 AND NOTICE OF
VIOLATION
Dear Mr. Ray:
From March 15 through April'25,1998, a routine inspection was conducted at your San Onofre
Nuclear Generating Station, Units 2 and 3 reactor facilities. The enclosed report presents the
scope and results of that inspection.
During the 6-week penod covered by this inspection, your conduct of activities at the San Onofre
facilities was generally characterized by safety-conscious operation, sound engineering and
maintenance practices, and careful radiological work controls.
Four violations of NRC requirements were identified during this inspection. We have carefully
considered the perspectives you expressed at the exit meeting in arriving at our enforcement
decisions. We encourage open communication, as occurred during the exit meeting, to facilitate
a mutual understanding of the facts, your perspectives regarding the issues, and the basis for
our regulatory conclusions. We understand that you do not dispute the facts as discussed at the
exit meeting. The disagreement centered around the application of NRC's Enforcement Policy.
I personally discussed these issues with Mr. Russ Kneger of your staff to ensure a mutual
understanding of the issues. Subsequent to that discussion, my resolutica of the concerns
expressed at the exit meeting, as documented below, was reviewed by NRC's Office of
Enforcement to ensure the proper application of the Enforcement Policy.
Violation A, regarding a failure to follow procedures that resulted in a minor pressure and level
transient in two safety injection tanks had only negligible safety consequence. However, the
regulatory significance of the procedure noncompliance in this instance was not minor, because
the potential impact of consciously deviating from approved procedures without appropriate
review was of regulatory concem. In applying the guidance of Enforcement Guidance
Memoranda 97-12 and 97-12A to this issue, the NRC determined that the criteria for a noncited
violation were not met in that the noncompliance was revealed through a self-disclosing event
and that the cauce of the event was obvious.

Violation B, regarding another procedural compliance issue resulting from a cognitive
maintenance error, was also not considered minor becauee prompt operator response was
required to mitigate the reactor coolant system pressure transient induced by the maintenance
error. in applying the guidance of Enforcement Guidance Memoranda 97-12 and 97-12A to this
issue, the NRC determined that the criteria for a noncited violation were not met in that the
noncompliance was revealed through a self-disclosing event and that the cause of the event
was obvious.-
Violation C, regarding a failure to perform a safety evaluation required by 10 CFR 50.59, was
determined not to be minor because a plant modification was actually completed without
appropriate evaluation. Because the failure was identified by the NRC, the criteria for a noncited
violation were not met.
Violation D, regarding the failure to comply with contamination control procedures, was not
considered to be minor because of the potential spread of contamination, particularly if the
incident recurred several times. Because the failure was identified by the NRC, the criteria for a
noncited violation were not met.
The NRC has concluded that the information regarding the rcasons for the violations, the
corrective actions taken and planned to correct the violations and prevent recurrences are
already adequately addressed on the docket in the enclosed inspection report. T'1erefore, you
.
are not required to respond to this letter in regards to the violations unless the description therein
does not accurately reflect your corrective actions or your position. In that case, or if you choose
to provide additional information, you should follow the instructions in the enclosed Notice.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of thia letter, its
enclosures, and your response will b3 placed in the NRC Public Document Room.
Should you have any questions conceming this inspection, we will be pleased to discuss them
with you.
