SUBJECT: NRC INTEGRATED INSPECTION REPORT NO. 50-327/99-04 AND
50-328/99-04
Dear Mr. Scalice:
'
On July 17,1999, the NRC completed an inspection at your Sequoyah 1 & 2 reactor facilities.
' The enclosed report presents the results of this inspection. The results of the inspection were
discussed on July 26 and again on August 9,1999, with Mr. M. Bajestani and other members of
- your staff.
The inspection was an examination of activities conducted under your license as they relate to
L safety and compliance with the Commission's rules and regulations and with the conditions of
your license. Within these areas the inspection consisted of a selective examination of
procedures and representative records, observations of activities, and interviews with
personnel. Because the Sequoyah facility is participating in the NRC's Power Reactor
Oversight Pilot Plant Study, the evaluation of regulatory issues documented in this inspection
repost were evaluated and dispositioned in accordance with Appendix F: Interim Enforcement
Policy for Use During the NRC Power Reactor Oversight Process Pilot Plant Study, of the NRC
Enforcement Policy.
Based on the results of this inspection, one potentially safety significant issue was identified.
On June 30,1999, inadequate performance of the storm drain system caused water from a
heavy rainfall to backup and flood the turbine building railroad bay where the 6.9kv unit boards
were located, creating the potential for a loss of offsite power. Three findings were identified I
during the event review and are discussed in the enclosed inspection report. One of these
issues is identified as an apparent violation for failure to incorporate the storm drain system into
the Maintenance Rule program. This apparent violation is pending completion of a
_ determination of significance for the flooding event, under the NRC Significance Determination
Process (SDP). Another issue, involving corrective action from a previous flooding event, is
unresolved, pending further NRC review. Upon completion of our review, we will inform you of
our final significance determination of these issues and any associated enforcement action.
!
One apparent violation was identifiexf associated with the implementation of procedural changes
to leave three containment penetrations open during fuel movement. These procedure j
changes were implemented without prior Commission approval, as required by 10 CFR 50.59,
;and, in effect, resulted in a change to the technical specifications. As discussed in Appendix F T

 of the NRC Enforcement Policy, violations at facilities participating in the pilot plant study that
 impact the NRC's ability for oversight of licensee activities, such as those involving 10 CFR
 50.59 issues, are not evaluated by the SDP. Instead, these issues will be dispositioned in
 accordance with the current NRC Enforcement Policy. Therefore, the significance and
 characterization of this apparent violation is pending NRC review, and you will be contacted at a
 later date regarding the results of our deliberations.
 The NRC also identified six additional issues of low safety significance that have, as appropriate,
 been entered into your corrective action program and are discussed in the summary of findings
 and in the body of the attached inspection repor1. Of the six issues, five were determined to
 involve violations of NRC requirements, but, because of their low safety significance, the
 violations are not cited. If you contest these non-cited violations, you should provide a response
 within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear
 Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with
 copies to the Regional Administrator, Region ll; the Director, Office of Enforcement, United
 States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident
 Inspector at the Sequoyah facility.
 In accordance with 10 CFR 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.
