Attention:

Gentlemen:
SUBJECT:
NRC INSPECTION OF WASHINGTON NUCLEAR PLANT UNIT'2
This refers to the maintenance
team inspection
conducted
by Mr; A. Toth and
other members of our staff during May 21 through June
15,
1990.
This
inspection
examined your activities
as authorized
by
NRC License
No.
Discussions
of our findings were held with Mr.
C.
Powers
and other members of
your staff at the conclusion of the inspection
and
an exit meeting
was held at
the
WNP-2 site
on June 26,
1990.
Areas examined during this inspection are described
in the enclosed
inspection
report.
Within these
areas,
the inspection consisted of selective
examinations
, of procedures
and representative
records,
interviews with personnel
and
observations
by the inspectors.
Ins ection Overview
The purpose of this inspection
was to determine the effectiveness
of the total
integrated
maintenance
process at the Washington Nuclear Plant Unit 2,'to
assure that components,
systems,
and structures of the facilities are
adequately
maintained
so that they are available to perform their intended
functions.
Specific inspection
emphasis
was focused
on the following
objectives:
~ ~
1.
Assess the effectiveness
of the maintenance
program to avoid challenges
to'afety
systems
from transients initiated or made more severe" by equipment
failures
due to maintenance
weaknesses":
=-
.2.
Assess
the effectiveness
of quality verification organizations
in
contributing to the identification, resolution,
and prevention of safety
significant technical
problems
and deficiencies
in plant systems
and
'perations.
3.
Assess
the effectiveness
of problem identification and resolution
processes,
including awareness
and actions regarding industry initiatives
in equipment performance monitoring and preventive maintenance.
4.
Assess
the status of corrective actions
for, self-assessment
efforts in the
maintenance
area.

Overall
Conclusi ons
The overall maintenance
program for WNP-2 appeared
to be adequately
defined
and
addressed
current industry maintenance
program initiatives.
The maintenance
program reflected
management
support
and involvement as well as
a commitment to
improved standards
of performance.
Significant resources
appear to have
b'een
allocated to current programs
which should
improve maintenance
work control
programs.
The team also observed that many of the observations
of this
inspection
agreed with the results of licensee
self-assessment
activities
and
management
overview programs.
Continued
management efforts in this regard are
strongly encouraged.
Although 'a program to improve maintenance
procedures
and instructions
has
been
initiated, delays in implementation
appeared
to have contributed to
instances'f
poor control of work during the current outage.
The team noted that the
maintenance
program was not fully effective in preventing incorrect work
practices.
Detailed examples of these
observations
are discussed
in the
attached
report.
During the exit meeting,
the team also noted
a recent event
which appeared
to indicate
a need for closer attention to equipment performance
trending.
Specifically, the team noted that proper trending of bearing oil
consumption
would likely have resulted in more timely repair of a Division I
emergency diesel
generator,
which recently failed because
of lubrication
problems.
This appears
to be
an area requiring additional
management
involvement.
The team acknowledged that current efforts to develop
a
Reliability Centered
Maintenance
(RCM) program appeared
to address
the trending
concern
and should provide for more timely detection of equipment problems.
The discovery of unauthorized electrical splices in a temperature
indicating
circuit in containment,
as well as improper grounding of 25KV bus-work,
indicated
a need for improved work control procedures
and additional
emphasis
on procedure
compliance.
The event involving unauthorized splices,
although
not safety related work, was caused
by failure to comply with plant procedures
by both supervisory
and engineering
personnel,
as well as by the directly
involved craft technicians.
This was of particular concern
from a programmatic
standpoint,
since the involved personnel
appeared
to believe that they were
working on safety related,
environmentally qualified equipment
cover'ed
by the
equality Assurance
program.
Nevertheless,
the workmen deviated
from their work
instructions without first obtaining proper authorization
and,
even worse,
.
documented that the task was accomplished
in accordance
with the procedure
and
did not document their actions.
Furthermore,
the work activity was apparently
not monitored or checked
by the craft supervisor
and involved gC personnel
did
not react to a bypassed
gC hold point.
These actions
appear to be indicative
of, an attitude
by these
personnel
which is inconsistent with your plant policy
and procedures.
We urge you to assess
whether this attitude is wide-spread
and
take corrective action accordingly.
The team observed that you have delayed repair of a safety related Control
Room
emergency chiller unit for approximately
27 months,
on the basis that the unit
was not specifically covered
by plant Technical Specifications.
Since this
specific problem was determined to not be particularly s'afety significant,
we
have not issued
a Notice of Violation, however,
we consider that you did not
implement appropriate corrective actions in accordance
with the requirements
of
your equality Assurance
program.

Ma 'or Concerns
Hi hli hted
b
this Ins ection
As summarized
below and discussed
in detail in the attached
report,
the
inspection
team identified concerns
that:
l.
In some instances
plant personnel
appeared willing to accept
inadequate
work instructions
and to depart
from work instructions without proper
authorization.
2.
In some instances
plant personnel
appeared
to fail to recognize
needed
corrective actions.
3.
Plant personnel
appeared willing to defer
needed corrective actions.
In this regard,
the team noted that, in some instances,
the plant staff
appeared
to rationalize regulatory requirements
at the expense
of
timely corrective action,
Me would appreciate
your comments
addressing
the above concerns,
including
the expected
date for restoring operability of chiller CCH-CR-1A.
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.
Should you have
any questions
concerning this in'spection,
we will be glad to
discuss
them with you.
Sincerely,
~
