Dear Mr. Clark:

SUBJECT:
LETTER OF REPRIMAND
(NRC INSPECTION REPORT NO. 50-341/87027(DRS))
This refers to the inspection conducted during the period July 1-10, 1987, of
activities at the Fermi Power Plant, Unit 2.
The inspection focused on the
circumstances that led to an uncontrolled increase in reactor temperature and
an unplanned change from Mode 4 (cold shutdown) to Mode 3 (hot shutdown). As
a result of this inspection, the NRC staff has determined that you did not, in
all respects, comply with the requirements of your Senior Operator's License.
The details of the events that led to this problem are presented in the subject
inspection report which is enclosed with this letter. On July 31, 1987, we
held an enforcement conference in the NRC Region III office with you and others
of the Fermi Power Plant staff. During the conference, we discussed the event
and its root causes.
Tne inspection determined that, on June 26, 1987, while in the position of
Nuclear Shift Supervisor, you failed to remain cognizant of existing plant
conditions and did not take proper steps to ensure your subordinates properly
performed their assigned duties.
During this time, there existed an uncontrolled
increase in reactor water temperature at the rate of 10 decrees Fahrenheit per
hour and the temperature exceeded the 200 degree Fahrenheit Mode 4 limit.
Your failure to be cognizant of all reactor water temperature traces clearly
indicating a steady heat-up and to adequately discharge your supervisory
responsibility contributed to the plant experiencing an unplanned change
to Mode 3 in violation of the facility's Technical Specifications.
Your Senior Operator's License requires that you observe the operating procedures
and other conditions specified in the facility license which autnorizes operation
of Fermi Power Plant, Unit 2.
Fermi Technical Specification 6.8.1.a requires
that writt e procedures be established, implemented, and maintained covering
the applicable procedures recommended in Appendix A of Regulatory Guide 1.33,
Revision 2, February 1978. One of the procedures recommended in Appendix A
of Regulatory Guide 1.33 deals with Authorities and Responsibilities for Safe
Operation and Shutdown. Technical Specification 6.8.1.a is implemented by the
Detroit Edison Company Plant Operations Manual (POM). POM Procedure 12.000.57,
Nuclear Production Organization," Revision 3, Paragraph 5.2.3, requires that
the Nuclear Shift Supervisor (NSS) maintain the broadest perspective of
operational conditions affecting the safety of the plant as a matter of highest
priority.
Paragraph 5.2.3 further requires the NSS to supervise the operation
of the plant and control room to ensure compliance with Technical Specifications.

SEP 2 41987
The NRC staff has con' luded that your lack of attention to the reactor water
c
temperature,- one of the critical safety related parameters in cold shutdown
(Mode 4), and your failure to ensure that your subordinates properly performed
their assigned duties demonstrates a level of performance below that required
of a licensed senior operator to ensure the safe operation of the reactor and
,
to protect the health and safety of the public.
4
Accordingly, this " Letter of Reprimand" is issued to emphasize that your level
.
of performance as a licensed operator on June 26, 1987 was unacceptable and
that similar conduct in the future could result in significant enforcement
i
sanctions. These sanctions could include:
a Notice of Violation, suspension,
i
modification or revocation of your license and/or the issuance of a civil penalty.
1
In the future the NRC will, in accordance with its Enforcement Policy, take
l
!
whatever steps are necessary to ensure that you carry out licensed activities
in a manner that is consistent with plant safety as well as the health and
safety of the public. A copy of-this Letter of Reprimand will be placed in
l
your official file. Should future evaluation of your performance as a licensed
)
operator be necessary, this letter may be considered as part of that evaluation.
Should you choose to, you may file a written response to this letter which will
{
be included in your official file.
However, based on the information you
4
provided at the enforcement conference, a written response to this letter
{
is not required.
]
Enforcement action is also being taken against your employer, Detroit Edison
Compan.y, as well as three other licensed individuals who were directly involved
in the June 26, 1987 unplanned mode change event.
In accordance with
1
Section 2.790 of the NRC's Rules of Practice, Part 2, Title 10, Code of
Federal Regulations, copies of all this correspondence will be placed in
the NRC Public Document Room. Copies are also enclosed for your information.
Sincerely,
W
A. Bert Davis
Regional Administrator
