Dear Mr. Murphy:
SUBJECT:
REACTIVE REVIEW 0F POTENTIAL TAMPERING EVENT
This refers to the inspection conducted by Mr. J.
.R. Creed of this office
between February 4 and April 21, 1994.
The inspection included a review of
authorized activities for your LaSalle Nuclear Power Plant.
Areas examined
during the inspection are identified in the report. ' Within these areas, the
inspection consisted of selective examinations of records, interviews with
personnel, and observations of plant equipment.
No violations of NRC requirements were identified during the course of this
inspection.
We concluded, however, that foreign material was intentionally introduced into
one of your lubricating systems. Although unable to be proven conclusively,
it appears more likely than not that this was the result of poor work
oractices rather than a malevolent act. However, despite early indications of
intentional tampering, your Problem Identification Program and event screening
!
process were apparently not initially effective in highlighting this issue.
1
Consequently, adequate security evaluation of this matter was delayed.
The
l
corrective action taken to address the first incident by your site staff was,
l
l
by your own . evaluation, inadequate.
Clear initial indications of intentional misuse or tampering with systems ~ need
be addressed more aggressively and more timely, with a team capable of
evaluating both the operational and security aspects of the facts. Better
-coordination between site operating staff, security specialists and corporate
investigators should be developed.
This might include criteria for action, a
method or procedures providing guidance for determining whether an abnormal
plant condition could have a reasonable explanation or could be intentional.
A stronger questioning attitude may help in developing accurate evaluation of
potential tampering events sooner.
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of
this letter and the enclosed inspection report will be placed in the NRC
,
)
Public Document Room.
