Gentlemen:
<
' Enclosed .for your review, prior to our scheduled meeting of January 4,1990,
'
is the Initial SALP'8' Report for the Zion Nuclear Plant, covering the period
.
June 1,-1988 through September 30, 1989.
,
In accordance with NRC policy, I have reviewed the SALP Board Assessment and
!
concur with their ratings.
It is my view that your conduc.t of nuclear
'
y
activities 'in connection-with the Zion facility is satisfactory. The areas.
of. Plant Operations, Maintenance / Surveillance, and Radiological Controls
each received a SALP Category 2, remaining at a -consistent- level of perform-
ance.
I- note that o)erations management still occasionally continues to
narrowly interpret tie Technical Specifications and does not routinely consult
the Final Safety Analysis Report for operability considerations, as: also noted-
in the previous SALP Report. As a result, non-conservative decisions' on
system operability have occurred on several occasions.
For example, the-
o)erations staff did not consider the containment, spray system inoperable
'
wien.the suction path to one train used during the recirculation phase was
inoperable. This resulted in the unit exceeding the 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> LCO action
..'
statement. More recently, the operability of the Emergency Diesel' Generators
was not questioned when the ventilation system that serves a support function
was found inoperable..
Engineering / Technical Support continued to be rated a Category 3.
There
were many examples of deficient operational conditions where engineering
involvement was lacking. Weaknesses were observed in engineering support
for maintenance and surveillance activities. Specifically, weaknesses were
noted in evaluation of problem root-cause, response to industry information
and vendor recommendations,'and formulation of post-maintenance testing
requirements. This resulted, for example, in accepting repeated failures
g
of battery-to-bus circuit breakers and failure to adequately test the

auxiliary feed water pump overspeed trip function.
In a number of instances,
oversight and management of contractor services were inadequate.
For example,
failure'to establish a correlation between Main Steam Safety Valve testing
methods performed by.a contractor resulted in the plant cperating outside the_
i
.{
design basis twice during this assessment period. Management oversight of
preparations for the licensed operator requalification exam was insufficient
and the station's requalification program was found to be unsatisfactory.
Finally, weaknesses were noted in performance of safety evaluations, in
technical quality of many licensing submittals, and in the completeness of
surveillance procedures. We recognize that actions have been taken to
address many of these weaknesses.
You should continue to give close
management attention to your engineering and technical support activities.
Security was rated a Category 2 with a declining trend compared to a Category 1
during the previous assessment period. The performance decline was apparent
in the failure to adequately evaluate the impact of the new service building
construction on security barriers, and in management weaknesses associated
i
with this and other security matters. The Regulatory Effectiveness Review
i
(RER) of the security program also indicated significant performance weaknesses.
Emergency Preparedness was rated a Category 2, a decline from the previous
assessment period. The decline was attributed to plant performance weaknesses.
We acknowledge your aggressive actions to correct these weaknesses and that
the exercise was challenging. A new functional area, Safety Assessment / Quality
Verification, was rated a Category 2.
On the positive side, I note that extensive programs are )resently in place
to address weaknesses identified during this period. Altlough it is too
early to assess the effectiveness of these programs, improvements have been
noted in the areas of housekeeping, material condition and station personnel
communication and cooperation.
At the SALP meeting you should be prepared to discuss our assessments and
your plans to improve performance. The meeting is intended to be a candid
dialogue wherein any comments you may have regarding our report are discussed.
Additionally, you are requested to respond in writing specifically addressing
corrective actions planned to improve your performance in the areas of
Engineering /T.echnical Support and Security. This response should include
specific actions and dates by which these actions will be taken.
Your written
response should be provided within 30 days after the meeting. Your comments,
a summary of our meeting, and my disposition of your comments will be issued as
the Final SALP Report.
In accordance with Section 2.790 of the NRC's " Rules of Practice", Part 2,
Title 10, Code of Federal Regulations, a copy of this letter and the Initial
SALP Report will be placed in the NRC's Public Document Room.
