SUBJECT: SYSTEMATIC ASSESSMENT OF LICENSEE PERFORMANCE (SALP)
SEQUOYAH NUCLEAR PLANT REPORT NO. 50-327/93-43 AND 50-328/93-43
The NRC Systematic Assessment of Licensee Performance (SALP) has been
completed for your Sequoyah Nuclear Plant. The facility was evaluated for the
period of August 2, 1992, through October 9, 1993. The results of the
evaluation are documented in the enclosed SALP report. This report will be
discussed with you at a public meeting to be held at the Sequoyah site on
December 14, 1993, at 2:00 p.m.
-
This SALP was conducted under the revised SALP process that was implemented by-
the Nuclear Regulatory Commission on July 19, 1993. The revised SALP process
rates licensees in four functional areas: Operations, Maintenance,
Engineering and Plant Support. The Plant Support area includes: radiological
controls, security, emergency preparedness, fire protection, chemistry, and
housekeeping controls.
The performance of Sequoyah has declined in the Operations and Maintenance
functional areas, and the improving trend observed in Engineering in the
previous assessment period was not sustained. The second half of the
assessment period was characterized by an increased emphasis by licensee
management on this decline and establishment of a restart plan to correct
problems in the areas of operations, technical programs, backlogs, balance of
plant material condition, and other management issues.
In.the Operations area, a lack of management involvement and safety
sensitivity was noted early in the assessment period. Configuration control
issues due to poor personnel performance and procedural problems continued to
be a challenge throughout the period.
Late in the assessment period,
management involvement in addressing these and other Operations concerns was
observed. As in the previous assessment period, operators continued to
perform well in responding to plant transients.
~
In the Maintenance area, it was noted early in the assessment period that
plant management had not provided sufficient oversight, resources, and
emphasis in maintaining secondary equipment, resulting in several plant

transients. Although the overall condition of the safety related portion of
the plant was generally adequate, improvement could also be achieved there as
well. A lack of attention to detail and procedural problems during
maintenance indicated that management involvement and oversight have not been
fully effective in instilling the appropriate sensitivity among plant
personnel as to the importance of procedural adherence and quality of.
maintenance activities.
Lack of configuration control during maintenance and
fragmented management of the inservice inspection program were also
identified. TVA management should closely monitor progress regarding the
above weaknesses.
Overall, performance in the area of Engineering was adequate.
Engineering
assessments of balance of plant systems during the dual .unn outage identified
,
modifications and repairs to improve the reliability of the 3e systems. The
quality of design change packages, the technical support provided to
operations, and the performance of system engineers was found to be
satisfactory. Weaknesses were identified in engineering evaluations, and
operators were challenged by some design deficiencies.
In the Plant Support area, effective programs were implemented in areas of
radiological controls, chemistry, emergency preparedness and security.
Strengths were noted in the ALARA program and accomplishments in the area of
,
exposure control. Also noted as a strength was the overall processing of
radwaste, including shipping.
Effective training programs'in Security and
Emergency Preparedness were reflected by well performed drills and exercises.
Room for improvement was noted in procedural adherence in radiation controls.
The fire protection program was adequately implemented, however, continued
support should be given to program improvements and system material condition.
Our reviews of your self-assessment efforts indicate that early in the
assessment period, plant management did not fully recognize the magnitude of
1
longstanding problems that existed at the site. These self-assessment
inadequacies resulted in an extended dual unit outage. Actions taken by
management resulted in programs that were proven to be generally effective
late in the assessment period. The internal and external assessments provided
meaningful input to the site management during Unit 2 restart efforts.
Plant
'
management was receptive to the identification and resolution of longstanding
problems. The continuation of critical self-assessments throughout your
organization over the long term is essential to address the many challenges
that have been identified throughout the SALP period.
Please provide a written response within 30 days to address the weaknesses
identified in the functional areas of Operations and Maintenance.
In
addition, please be prepared to discuss performance and planned actions in
these functional areas during the SALP presentation of December 14, 1993.
In accordance with Section 2.790 of the NRC's " Rules of Practice," a copy of-
this letter and its enclosure will be placed in the NRC Public Document Room.
