The following is in response to NRC Inspection Report 50-155/87010 (DRSS) dated
September 4, 1987, regarding alleged tampering at the Big Rock Point Plant.
Corrective actions for deficiencies noted within the report are outlined in the
following.
1) Deficiency
"Neither the site nor Corporate Security departments were advised of the
verbal threat to a valve and the subsevent degraded mode of valve CV-4050
so they could determine if a reportable event was required under the
criteria of 10 CFR 73.71(c).
Security was advised only of the verbal
confrontations and graffiti incidents involving a worker."
Response
The Plant Manager has advised all employees by memorandum dated August 12, 1987,
of their responsibilities to report future incidents to site management in
a timely manner. Additionally, General Employee Training is being modified
to more clearly define individual security responsibilities.
Completion Date - The Plant Manager's memorandum was issued on August 12, 1987.
General Employee Training will be revised by November 9, 1987.
2) Deficiency
"A thorough investigation of the potential valve tampering event and the
threat against the valve was not performed by the Plant staff or the Field
Maintenance Services - West (FMS-W) group. Both agencies investigated the
verbal confrontations and graffiti incidents. Each agency thought the
other conducted an investigation of the potential valve tampering event."
Response
The Corporate Security staff is developing a procedure to outline investi-
gative responsibilities for incidents of potential tampering.
Completion Date - November 9, 1987.
3) Deficiency
"No effective procedures were in existence to address needed investigation
of deliberate acts directed against Plant equipment even though I&E Information Notice 83-27, dated Kay 4,
1983, identified the need for such procedures or
guidelines. The I&E Information Notice was sent to the site Security
Section for information purposes about four years ago."

Response
The Corporate Security staff is developing a procedure addressing investi-
gations of deliberate acts directed against Plant equipment.
Completion Date - November 9, 1987.
4)
Deficiency
"The Senior Resident Inspector (SRI) was not advised of the threat against
the valve or degraded mode of the valve even though the licensee later
--
characterized the incident as having the potential of interrupting Plant
operations and jeopardizing the Company's license to operate a nuclear
facility. The SRI was only advised that a person's site access was terminated
because of verbal confrontations and writing graffiti. The SRI was not
advised of the subsequent more significant licensee conclusions pertaining
to the individual and the event."
Response
The Corporate Security staf f is developing a procedure detailing individuals
to be notified, including the SRI, upon discovery of an incident.
Completion Date - November 9, 1987.
5) Deficiency
"The verbal threat against the valve which occurred on February 6, 1987,
was not immediately reported to the licensee's management by at least two
-
personnel who heard the threats. This represented the single greatest
failure on the part of the Plant staff."
Response
Timely notification to site management of potential tampering events to
site management was addressed in the Plant Manager's memorandum dated
August 12, 1987. Timely reporting of events will be outlined in General
Employee Training and a procedure being developed by the Corporate Security
staff.
Completion Date - The Plant Hanager's memorandum was issued on August 12, 1987.
The procedure and General Employee Training revision will be completed by
November 9,
1987.

6) Deficiency
" Management actions after the threat against the valve became known
(February 19, 1987), were not aggressive. A walkdown of the poison control
system on February 13, 1987, was completed prior to management knowledge of
the threat and complete knowledge of the degraded mode of the valve. No
subsequent check or inspection was conducted because of the incident.
Although the Plant Review Committee (PRC) reviewed the verbal confrontation
and graffiti incidents, the investigation found no evidence that the threat
against the valve and subsequent degraded mode of the valve was reviewed by
the PRC. Additionally, the two technicians work was just_ routinely reviewed,
no additional review actions were taken based on the threat or detected
degraded mode of the valve."
Response
The Corporate Security staff is developing a. procedure outlining management
responsibilities, provisions to inspect equipment and making this informa-
tion available to the Plant Review Committee.
Completion Date - November 9, 1987,
1
7) Deficiency
" Management's actions in reference to the valve incident indicated that
management was not aware of the true significance of tampering wich' Plant
equipment.
(Section 236.b of the Atomic Energy Act designates such an
offense of punishable by a $10,000 fine , imprisonment for up to ten years
or both.)
>
Response
The Plant Manager's memorandum dated August 12, 1987, stressed the signifi-
cance of tampering with Plant equipment. Additionally, General Employee
Training is being revised to reflect the significance of tampering events.
Completion Date - The Plant Managers's memorandum was issued on August 12, 1987.
General Employee Training will be revised by November 9, 1987.
