SUBJECT:
SAFETY SYSTEMS OUTAGE MODIFICATION INSPECTION (DESIGN)
i
50-285/85-22
'
This letter conveys the results and conclusions of the design portion
of the Fort Calhoun Station Safety Systems Outage Modification Inspection
-
,
conducted by the NRC's Office of Inspection and Enforcement.
The
i
inspection team was composed of personnel from the NRC's Office of
Inspection and Enforcement and consultants.
The inspection took place at
4
i
the Fort Calhoun Station and at your offices in Omaha, Nebraska.
This
'
inspection was part of a trial NRC program being implemented to examine
the adequacy of licensee management and control of modifications performed
during_ major plant outages.
!
The purpose of this portion of the Safety Systems Outage Modification
Inspection Program was to examine, on a sampling basis, the detailed design
and engineering which was required to support the outage.
Coordination with
. teams conducting other portions of the inspection, including vendor inspections,
installation inspection, and the preoperations inspection, was required.
At
the conclusion of these inspections the NRC will provide a report summarizing
i
L
these efforts.
The items identified by the team during the inspection have been classified as
deficiencies, unresolved items, and observations,
Deficiencies regarding errors.,

~
procedural-violations and inconsistencies are identified in the report.
'
Unresolved items are identified where more information is needed-to reach
. '.
, conclusions.
Other observations are identified where it_was considered appropriate
'
'to. cal 1~your attention to matters which are not deficiencies or unresolved items,
but which are recommended for your consideration.
Chapter 1 of the report provides a summary of the results of the inspection
I
and the conclusions reached by the inspection team.
There appear to be
several significant weaknesses which were identified in your design control
processes.
One of these was your failure to obtain, maintain and use design basis
information to assure that the original design margins are not unintentionally
abrogated.
We are also concerned that post-modification testing procedures
were inadequate to confirm that the physical modifications fulfill the
functional design requirements of the system or component.
Several problems
relating to your performance of safety evaluations required by 10 CFR 50.59
and handling of emergency modifications were also identified.
One finding
identified that you had failed to modify a support and adequately analyze a

piping subsystem in the auxiliary feedwater system in accordance with your
specific commitments to the NRC.
During the installation portion of this inspection, the NRC performed a
preliminary review of your planned corrective actions for the significant
findings which were identified at the interim status briefing on October 8,
1985.
These included both short term actions to be completed prior to return
.
to operation and long term corrective actions.
A more detailed review of your
corrective actions, both long term and short term, will be conducted after the
60 day period allowed for your response to this inspection report.
You should respond in writing to the deficiencies and unresolved items within 60
days after receipt of this letter.
In your assessment of individual deficiencies
identified in the inspection report, you are requested to address the cause, the
extent to which the condition may be reflected in the unreviewed portion of the
design, actiori'to correct the existing condition, action to prevent recurrence,
and any other information you consider relevant.
For unresolved items, the
response should provide information needed to reach conclusions concerning accept-
ability of the specific feature or practice involved.
Comments on observations
may be included in your response.
Several of the items identified by the team may
be considered Potential Enforcement Findings.
Formal enforcement actions,
including any further actions required, will be identified subsequent to the
60 day period allowed for your response.
These will be included in the summary
report of the trial outage inspection.
In accordance with 10 CFR 2.790(a), a copy of this letter and the enclosures
will be placed in the NRC Public Document Room.
