Dear Mr. Koralewski:
l
SUBJECT:
LETTER OF REPRIMAND
(NRC INSPECTION REPORT NO. 50-341/87027(DRS))
l
l
I
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
l
the circumstances that led to an uncontrolled increase in reactor temperature
end 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
Contrcl Room Nuclear Supervising Operator, you failed to remain cognizant of
plant conditions and you delegated your responsibility for monitoring and
controlling reactor water temperature to a trainee, an unlicensed individual,
without any further supervision. During this time, there existed an uncontrolled
increase in reactor water temperature at the rate of 10 degrees Fahrenheit per
hour and the temperature exceeded the 200 degrees Fahrenheit Mode 4 limit. Your
failure to be cognizant of all reactor water temperature traces clearly indi-
cating a steady heat-up contributed to the plant experiencing an unplanned
change to Mode 3 in violation of the facility's Technical Specifications.
Your Senior Operation's License requires that you observe the operating pro-
cedures 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 addressed in
Appendix A of Regulatory Guide 1.33 deals with Authorities and Responsibilities
of Safe Operation and Shutdown. Technical Specification 6.8.1.a is implemented
by the Detroit Edison Company Plant Operations Manual (P0M).
POM Procedure
12.000.057, " Nuclear Production Organization," Revision 3, Paragraph 5.2.5,
requires that the Nuclear Supervising Operator (NS0) remain continuously
cognizant of the reactor power level and plant status.

The NRC staff has concluded that your delegation to a trainee,'without adequate
- supervision, of the monitoring and logging of reactor water temperature, one.
.
of the critical safety related parameters in cold shutdown (Mode 4), 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.
'1
i
Accordingly,. this " Letter of Reprimand" is issued to emphasize that your level
1
'
of performance as a licensed operator on June 26, 1987 was unacceptable and
i
'
that similar conduct in the future could result in significant enforcement
sanctions. These sanctions could. include:
'a Notice of Violation, suspension,
modification 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 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 % formation 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 and uncontrolled made change event.
In accor-
dance 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,
a8AW

Regional Administrator
