Dear Mr. Liu:
SUBJECT: NRC ENFORCEMENT CONFERENCE, REPORT NUMBER 50-331/93013(DRP)
This refers to an Enforcement Conference conducted by Mr. J. B. Martin and
other members of the Region III staff on July 29, 1993, regarding activities
at the Duane Arnold Energy Center and to the discussion of our findings with
your staff.
This Enforcement Conference was conducted as a result of the
findings of an inspection conducted from May 22 through July 7, 1993, and of
an event which occurred on July 22, 1993, in which two apparent violations of
NRC regulations were identified.
Inspection report (IR) 50-331/93009(DRP),
dated July 23, 1993, documented the results of the inspection conducted from
May 22 through July 7,1993, and the enclosed report documents the event which
occurred on July 22, 1993. The enclosed report summarizes the conference.
Based on the information presented in the Enforcement Conference and on
further review by the NRC, we have determined that escalated enforcen,ent is
not warranted for these matters.
However, certain of your activit ies appeared
to be in violation of NRC requirements, as specified in the enclosed Notice of
Violation (Notice). The first violation involved the "A" standby diesel
generator (SBDG) being inoperable for a time in excess of that allowed by
technical specifications.
However, the significance of the event was reduced
because the "B" SBDG was operable, all emergency core cooling systems were
operable, and the "A" SBDG could have been started by locally resetting the
j
Furthermore, the cause of the
"A" SBDG being inoperable
pG
j
appeared unavoidable by reasonable management controls or quality assurance
measures. Although the violation met the crite~ia for enforcement discretion,
we have chosen not to exercise this option because of the significance we
igI
attach to an emergency source of electrical power being inoperable for an
extended time period.
The second violation consisted of two examples of failure to follow procedures
by control room operators.
In the first example, a control room operator
incorrectly performed a step in a surveillance test procedure.
Due to this

failure, control room operators were naaware of the status of an important
emergency core cooling system compon a for about 14 hours1.62037e-4 days <br />0.00389 hours <br />2.314815e-5 weeks <br />5.327e-6 months <br /> even though the
condition was indicated on the "B" core spray mimic panel in the control room.
In the second example, on July 22, 1993, an operator omitted a portion of a
step in a surveillance test procedure. The step was correctly performed only
,
i
after the error was pointed out by the NRC inspector who witnessed the
surveillance test. These failures, combined with other recent problems
'
identified with shift briefings and inappropriate annunciators, raised
significant concerns that your control room operations have not been conducted
with an appropriate attention to detail and sensitivity for safety.
This
-
performance does not conform to the high standards of professionalism and
quality normally present and expected in the control room of a nuclear power
