Dear Mr. Trimai:
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 the 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.
The inspection determined that, on June 26, 1987, while in the position of
Assistant Nuclear Shift Supervisor, you failed to remain cognizant of existing
plant conditions and did not take proper steps to ensure your subordinates in
the control room properly performed their assigned duties. During this time,
there existed on uncontrolled increase in reactor water temperature at the
rate of 10 degrees 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 Technical Specifications.
Your Senior Operator's License requires that you observe the operating procedures
and other conditions specified in the facility license which authorizes operation
of Fermi Power Plant, Unit 2.
Fermi Technical Specification 6.8.1.a requires
that written 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 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).
P0M Procedure 12.000.57, " Nuclear
Production Organization," Revision 3, Paragraph 5.2.4.5, requires that the
Nuclear Assistant Shift Supervisor (NASS) assist the Nuclear Shift Supervisor
(NSS) in the operation of the plant and control room under all conditions,
ensuring compliance with all applicable procedures and regulations.

The NRC staff has concluded that your lack of attention to the reactor water
temperature, one of the critical safety related parameters in cold shutdown
(Mode 4), and your failure tc, 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
protect the health and safety of the public.
l
Accordingly, this " Letter of Reprimand" is issued to emphasize that your level
l
of performance as a licensed operator on June 26, 1987 was unacceptable and that
similar conduct in the future could result in significant enforcement sanctions.
'
l
These sanctions could include:
a Notice of Violation, suspension, modification
l
or revocation of your license and/or the issuance of a civil penalty.
In the
future the NRC will, in accordance with.its Enforcement Policy, take 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 your official
file.
Should future evaluation of your performance as a licensed opert. tor
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 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
Company, as well as three other licensed individuals who were directly involved
in the June 26, 1987 unplanned mode change event.
In accordance with
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,
hhAbb
